Description

  The present invention relates to a method for attaching an extension eyelash. In particular, the present invention relates to a method for attaching a flat-shaped extension eyelash to a ground eyelash.

  There is a false eyelash as one of the items to give length and volume to the eyelashes and to produce larger, beautiful and attractive eyes. False eyelashes can give length and volume to the user's eyelashes by putting together a plurality of artificial eyelashes, providing an adhesive part at the end and attaching the adhesive part to the user's eyelid (for example, Patent documents 1, 2 etc.). Since the false eyelashes adhere to the skin of the user, the feeling of wearing is poor and in some cases the skin may be covered.

  On the other hand, in recent years, an artificial eyelash called a so-called eyelash extension having a volume and a length substantially equal to that of a single eyelash has been proposed (for example, Patent Document 3). This eyelash extension (eyelash extension or extension eyelashes, artificial eyelashes) adheres directly to the eyelashes using an adhesive without adhering to the eyelids, so it has a good feeling of wearing and is less likely to be covered with the skin. In addition, since the eyelash extensions are adhered one by one to one eyelash, it is possible to give the eyelashes a length and volume with a natural feeling as compared with the eyelashes.

  The structure of a typical eyelash extension 1000 is shown in FIG. The eyelash extension 1000 shown in FIG. 1 is composed of an artificial eyelash main body 110 having a distal end 111 and a distal end 115. The artificial eyelash body 110 is made of chemical fiber and is made of a resin material (in particular, polybutylene terephthalate (PBT)). The cross-sectional shape of this eyelash extension 1000 (artificial eyelash main body 110) is circular (substantially circular).

  The eyelash extension 1000 shown in FIG. 1 is attached to the eyelashes 50 of a user (user) 55 as shown in FIGS. 2 (a) to 2 (c). First, as shown in FIG. 2A, a part of the eyelash extension 1000 (artificial eyelash main body 110) was grasped with the tweezers 60, and an adhesive (glue) 117 was applied to the end 115 of the eyelash extension 1000. In the state, bring the eyelash extension 1000 close to the eyelash 50.

  Next, as shown in FIG. 2B, the adhesive 117 of the eyelash extension 1000 is attached to the eyelash 50, and the eyelash extension 1000 is adhered to the eyelash 50. Then, when the adhesive 117 is cured and the eyelash extension 1000 is fixed to the eyelash 50, as shown in FIG. 2C, the tweezers 60 are removed, and the attachment of the eyelash extension 1000 is completed. Do this for each eyelash 50.

  The eyelash extension 1000 is housed in a case 2000 as shown in FIG. 3 before attachment to the eyelash 50 (treatment). The case 2000 shown in FIG. 3 is composed of a container portion 2100 for storing a large number of eyelash extensions 1000 and a lid portion 2200 for covering the container portion 2100. When taking out the eyelash extension 1000 from the container (container for eyelash extension) 2100 shown in FIG. 3, the lid portion 2200 of the container 2100 is opened, and a large number of eyelash extensions 1000 are put in the container portion 2100 carelessly. Then grasp only one with tweezers (60). Thus, after grasping one eyelash extension 1000 with the tweezers 60, it is attached to the eyelash 50 via the adhesive 117 as shown in FIGS. 2 (a) to 2 (c).

  However, it is difficult to properly grasp each of the thin and curved eyelash extensions 1000 with the tweezers 60, and furthermore, if not grasping at the correct position, the eyelash extensions 1000 in FIGS. 2 (a) to 2 (c). Installation (treatment) does not go well. Therefore, a container 2500 for selling the eyelashes extensions 1000 properly aligned and stored as shown in FIG. 4 is sold instead of randomly placing the large number of eyelashes extensions 1000 into the containers 2100.

  The container (container for eyelashes extension) 2500 shown in FIG. 4 includes a container portion 2300 for storing a mount 2350 to which a plurality of eyelash extensions 1000 are attached, and a lid portion 2400 serving as a lid of the container portion 2300. There is. In the container 2500, the eyelash extension 1000 is aligned in a row of blocks 1500 and affixed to a backing 2350. Then, the blocks 1500 of the eyelash extension 1000 are attached to the mount 2350 in a number of rows.

  Since the eyelashes extensions 1000 stored in the container 2500 shown in FIG. 4 are cleanly aligned, it is very easy to grasp one eyelashes extension 1000 with the tweezers 60. Specifically, by gripping and lifting a part of the eyelash extension 1000 (around the tip 111), the end 115 of the eyelash extension 1000 can be removed from the adhesive layer of the backing 2350, and only one eyelash extension 1000 can be easily removed. And can be picked up well. In addition, it is possible to easily grasp a desired part (a predetermined part in the central part from the tip part 111 of the artificial eyelash body part 110) accurately. Therefore, the installation (treatment) of the eyelash extension 1000 proceeds smoothly, and the burden on the practitioner and the person receiving the treatment is reduced.

  Also, one row of blocks 1500 has the same type of eyelash extension 1000 (the same length, curl curvature, color, etc., ie, the same part number), and the other row of blocks 1500 has a different type of eyelash extension 1000 It is possible to align. In this case, since a plurality of types of eyelash extensions 1000 can be placed in one container 2500, it is convenient because it becomes easy to meet the user's (user's) request.

  In the case of the container 2100 shown in FIG. 3, it is sufficient if a predetermined number of large number of eyelash extensions 1000 are stored in the container portion 2100. However, in the case of the container 2500 shown in FIG. You need to As shown in FIG. 5, the alignment of the eyelash extension 1000 (the alignment of the block 1500) is quite precise. Specifically, the tip 111 of the eyelash extension 1000 is against the reference line (reference height) 1300. Only those that are within ± 0.2 mm are considered good.

  Such extremely high-precision alignment work (alignment of eyelash extensions 1000) can not be performed by a machine, but is all performed manually, and requires a great deal of labor, cost, and skill of the worker. It has become. As a reference, although implantation of toothbrush bristles can be performed automatically by a machine, the alignment accuracy of the bristle tips is about ± 1 mm, and the alignment of highly accurate hair tips beyond that is currently automated. It is impossible with technology.

  The inventors of the present invention have made various studies in order to somehow reduce or avoid such alignment work, but no good method has been found. Specifically, first, if the alignment operation of the eyelash extension 1000 on the backing 2350 is simplified and the alignment is allowed even if the tip end portion 111 of the eyelash extension 1000 is broken with respect to the reference line 1300, The appearance of the container (product to be sold) 2500 storing the extension 1000 is not good, and it becomes an unsold item. On the other hand, we examined automation by machines capable of performing higher precision alignment, but we investigated to Japan and overseas, but such high precision alignable machines were not found. Since the eyelash extension 1000 is thin, light and soft, it is difficult to automate alignment by a machine. After all, depending on the shape of the hair and the type of the product, one by one eyelash extension 1000 should be manually attached to the backing 2350 or the uncurled hair should be stacked in a box-shaped container etc. The fact is that the quality is not stable, such as aligning in a row, aligning the ends of the hairs, and putting together a plurality of hairs at one time and attaching them to a tape.

  Furthermore, in the block 1500 of the eyelash extension 1000 (alignment of the eyelash extension 1000), it is necessary to uniformly align the curls of all the eyelash extensions 1000. In some cases, if the curled and uneven eyelash extension 1000 is mixed, the block 1500 and the product (container 2500) to which the plurality of blocks 1500 are attached will be defective. Therefore, it is necessary to control the curl of each of the eyelash extensions 1000 with high accuracy.

  In addition, in the eyelash extension industry, a lighter eyelash extension 1000 is required because of the wearing comfort. As a method of reducing the weight of the eyelash extension 1000, the artificial eyelash main body 110 may be made thinner, or the artificial eyelash main body 110 may be grooved to have a cross-sectional shape of a star. If the eyelash extension 1000 (artificial eyelash main body 110) becomes lighter, then the artificial eyelash main body 110, which is only light and difficult to handle during manufacture, becomes more difficult to handle. Also therefore, it becomes very difficult to cleanly align the lighter eyelash extensions 1000.

  Under such circumstances, the inventor of the present invention flattens the cross-sectional shape of the eyelash extension 1000 and develops the eyelash extension 100 which is lighter than the ordinary eyelash extension 100 having a circular cross section. Disclosed in the specification. According to the flat-shaped eyelash extension, a lighter eyelash extension can be made, and the alignment operation of the eyelash extension can be improved, and furthermore, the shape control of the curl can be facilitated.

  With the development of the inventor of the present application, the step of aligning the flat shape eyelashes extension has become easy, and the active use of the flat shape eyelashes extension has been opened up. As an essential problem of the eyelash extension 1000, there is a problem that the eyelash extension 1000 comes off the ground eyelash 50 for a fixed period. Of course, if the adhesive 117 with high adhesive strength can be used to suppress the detachment of the eyelash extension 1000, the adhesive 117 with high adhesive strength is often a highly stimulating high-intensity adhesive, There is a possibility that the user (user) 55 can avoid using the adhesive 117. On the other hand, although the mild stimulus type adhesive is preferred by the user (user) 55, the durability of the eyelash extension 1000 is reduced as compared with the high stimulus type adhesive.

  This invention is made in view of this point, The main purpose is to provide the attachment method of the extension eyelashes which can improve the persistence of an extension eyelash (lashes extension).

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In the following drawings, components having substantially the same functions are denoted by the same reference numerals for the sake of simplicity of the description. Further, matters other than the matters specifically mentioned in the present specification and matters necessary for the implementation of the present invention can be understood as design matters of a person skilled in the art based on prior art in the field. The present invention can be implemented based on the contents disclosed by the present specification and the drawings and technical common knowledge in the field. In addition, the present invention is not limited to the following embodiments.

  With reference to FIG. 6 to FIG. 10, an extension eyelash (hereinafter referred to as “extension” or “eyelash extension (matsuek)”) 100 according to an embodiment of the present invention will be described. FIG. 6 is a perspective view showing the configuration of the eyelash extension 100 of the present embodiment. 7 and 8 are a side view and a top view showing the configuration of the eyelash extension 100, respectively. FIG. 9 is a cross-sectional view showing the configuration of the distal end surface 15 a (or a portion in the vicinity thereof) of the eyelash extension 100. In FIG. 10, the upper surface side (or the lower surface side) of the eyelash extension 100 according to the present embodiment is the front side (100a) and the side surface side of the eyelash extension 100 is the front side so that the structure of the present embodiment can be easily understood. It shows what has been arranged by overlapping with the one (100b).

    The eyelash extension 100 according to this embodiment includes an artificial eyelash body 10 having a tip 11 and an end 15. The end 11 is a pointed end, but it does not have to be sharpened and may be shaped like a cut of the end. The end portion (root portion) 15 is a portion to which an adhesive (glue) is applied, and is a portion located in the vicinity of the end face 15 a of the artificial eyelash main body portion 10. The artificial eyelash main body 10 has a shape of eyelash type, and the artificial eyelash main body 10 is formed with a curve (curved portion 10c) that has a natural angle when attached to the eyelash 50 There is. The artificial eyelash body portion 10 of the present embodiment is made of a resin 12.

  The cross-sectional shape of the artificial eyelash body portion 10 of the present embodiment has a flat shape, and as shown in FIG. 9, the thickness (T) is half or less of the width (W) of the flat shape. . The cross section of the artificial eyelash body portion 10 of this embodiment is significantly flatter than that of the circular (substantially circular) shape of the eyelash extension 1000 shown in FIG. In the example of the present embodiment, the cross section of the artificial eyelash main body 10 is not formed with irregularities such as grooves, peaks and valleys, and the cross section of the artificial eyelash main body 10 has a smooth surface. ing.

  In the configuration of the present embodiment, the upper surface 10a-1 (first surface 10a) defining the flat thickness (T) and the lower surface 10a-2 (second surface 10a) are substantially parallel surfaces. ing. In addition, since the artificial eyelash main body 10 is entirely curved, the upper surface 10a-1 and the lower surface 10a-2 are not parallel surfaces extending in a horizontal plane, but are relatively parallel surfaces (substantially parallel surfaces) It is what has become. In the illustrated example, the upper surface 10a-1 and the lower surface 10a-2 extend as substantially flat surfaces. When the artificial eyelash body portion 10 of the present embodiment is linear, the upper surface 10a-1 (first surface 10a) and the lower surface 10a-2 (second surface 10a) are flat surfaces and are parallel to each other. When the upper surface 10a-1 (first surface 10a) and the lower surface 10a-2 (second surface 10a) are flat (or substantially flat), since they are flat, the adhesive can be more easily applied, and the adhesion becomes easy. There is an advantage that the alignment operation of the artificial eyelash body 10 is facilitated.

  Further, the first side surface 10b-1 (right surface 10b) defining the flat width (W) and the second side surface 10b-2 (left surface 10b) are configured to be substantially symmetrical. In the illustrated example, the first side surface 10 b-1 and the second side surface 10 b-2 are a part (circular arc) of the outer edge of a circular shape, but may have other shapes. In addition, the first side surface 10b-1 and the second side surface 10b-2 may be substantially flat (substantially straight in cross section), or the first side surface 10b-1 and the second side surface 10b-2 may be asymmetric. It is also possible to make things. When the first side face 10b-1 and the second side face 10b-2 are a part (or a curved shape) of the outer edge of a circle, the artificial eyelash body portion 10 compared to the straight line (the side face of the plane). Even if the eyelash extension 100 slightly deviates to the side, there is an advantage that adhesion can be held by the curved shape (side surface of the curved surface), and adhesion on such side is not originally desirable, but the technology of eyelash extension treatment is It can reduce the mental burden for unskilled workers. The width (W) of this embodiment is, as shown in FIG. 9, the dimension at which the distance between the first side surface 10b-1 and the second side surface 10b-2 is long (or the diameter of the artificial eyelash body 10) It means that.

  In the eyelash extension 100 of the present embodiment, the thickness (T) when the width (W) of the flat shape is 100 units is, for example, 50 units or less, typically 40 units or less. In the illustrated example, a configuration example of width (W) 0.2 mm and thickness (T) 0.07 mm is schematically shown, and in that case, the width (W) of the flat shape is 100 units. The thickness (T) is 35 units, but it is also possible to make the shape flat (for example, 30 units or less, 25 units or less). If the thickness (T) is half or less of the width (W) of the flat shape, it is possible to use other ratios including the absolute dimension (mm). Since many eyelash extensions 100 become thinner along tip 11, it is desirable to determine based on the dimension of end 15 (or end face 15a)

  To explain further, the width W (or the diameter when assuming a circular shape) of the end 15 of the artificial eyelash body 10 shown in the drawing is thicker than the width W (diameter) of the tip 11. However, the width W of the artificial eyelash body 10 can be made constant (or substantially integral). The artificial eyelash body 10 is slightly curved and the top of the tip 11 is pointed. In other words, the thickness T of the end 15 of the artificial eyelash body 10 is thicker than the width T of the tip 11. However, the top (tip) of the tip 11 may not be sharpened. The length of the artificial eyelash body portion 10 of this embodiment is, for example, 5 mm to 20 mm, and the width W of the end face 15a of the end portion 15 can be, for example, 0.07 mm to 1.0 mm. The thickness T of the end face 15a of the end portion 15 is equal to or less than half the width W of the end face 15a (in one example, 0.1 mm or more).

  The artificial eyelash body portion 10 of the present embodiment is made of a resin 12. In other words, the artificial eyelash body 10 is made of chemical fiber and made of resin material. The resin which comprises the artificial eyelash main-body part 10 of this embodiment is comprised from a polybutylene terephthalate, polyester, an acryl, a vinyl chloride, and nylon, for example. The artificial eyelash body portion 10 in this example is made of polybutylene terephthalate (PBT). The artificial eyelash body portion 10 of the present embodiment is composed of 95% or more (mass%) of polybutylene terephthalate (PBT).

  In addition to the black color, the artificial eyelash body 10 may be made of a colored material. The artificial eyelash body portion 10 can be made of colors such as, for example, dark brown, purple, blue, pink, silver, green, light orange, light gold, red, wine red, white, yellow, whereby color extension It is possible to realize

  According to the eyelash extension 100 of this embodiment, since the cross-sectional shape of the artificial eyelash main body 10 is flat, the weight (mass) of the eyelash extension 100 (artificial eyelash main body 10) is light (for example, half or less) )can do. Therefore, the wearing comfort can be improved. Furthermore, the eyelash extension 100 of this embodiment has the advantage of being both light and soft, as compared to the case in which the weight is reduced by making holes or grooves in the artificial eyelash main body. That is, the eyelash extension 100 (artificial eyelash main body 10) of the present embodiment is easier to bend than the case of the circular (substantially circular) eyelash extension and has a thinner portion, which improves the comfortability. Let Until now, even when trying to design a soft eyelash extension, it was only possible to change the material and review the manufacturing process, and it was difficult to construct a soft eyelash extension that could be said to be good at the product level. According to the configuration of the embodiment, a soft (and light) eyelash extension 100 can be realized. That is, according to the configuration of the present embodiment, light and soft hair (artificial hair, eyelash extension) can be realized.

  FIG. 11 is a view showing how the eyelash extension 100 of this embodiment is attached to the eyelash 50 of a user (wearer) 55. As shown in FIG. The eyelash extension 100 of the present embodiment is an artificial eyelash that extends the length of the eyelash 50 of the user 55, and is fixed to the eyelash 50 by an adhesive (glue) 20. As shown in FIG. 11, in the case of the eyelash extension 100 of this embodiment, the side of the wide surface (10a) in the flat shape of the end portion 15 of the artificial eyelash main body 10 is brought into contact with the eyelash 55 and fixed. This is because when the narrow surface (10b) side of the artificial eyelash body portion 10 is brought into contact with the eyelashes 55, the contact area is small and the eyelash extension 100 can be easily removed.

  Although the eyelash extension 100 according to the present embodiment is adhered to the eyelash 50 by the adhesive (glue) 20, the following force is applied as a factor to reduce the durability. The first is the force 500 (and 501) applied to the root of the eyelash extension 100 (and the ground eyelash 50). The force 500 applied at the base is generated when the eyes are closed and rubbed, and the peeling force (501) is strongly applied to this portion, which causes a decrease in the sustained force. Since the adhesive 20 is weak to the peeling force (501) and the impact (500), this force (500, 501) reduces the persistence of the eyelash extension 100. The longer the eyelash extension is, the more easily the durability is reduced. Therefore, in the case of the flat eyelash extension 100 of this embodiment, the effect of the force 500 can be reduced more than the thick circular eyelash extension. Even in the flat eyelash extension 100 of the embodiment, the force 500 is a factor of the reduction of the sustainability.

  Next, the force 550 for peeling off to roll is also a factor to reduce the durability. The curling-off force 550 is the force applied to the gap between the bond at the tip of the hair (the gap between the eyelash extension 100 and the ground eyelash 50), and the thick and hard eyelash extension (and the ground eyelash) The force to remove 20 becomes stronger. In the case of the flat eyelash extension 100 of the present embodiment, the effect of the force 550 can be reduced because it is thinner and softer than the thick circular eyelash extension, but the force of the flat eyelash extension 100 of the present embodiment is 550 Is the cause of the decline in sustainability. Also, the more closely the eyelash 50 is fitted, the less force this force 550 will take.

  Here, adhesion strength and how stress is applied will be described. FIGS. 12 (a) to 12 (d) illustrate four types of stress, and are diagrams for explaining that the adhesive strength varies depending on the type of external stress.

  FIG. 12 (a) shows tensile stress 600 acting between the first member 601 and the second member 602. An adhesive is applied to the contact surface between the first member 601 and the second member 602, and the adhesion in this case is about 1000 (relative value). Further, FIG. 12 (b) shows tensile shear stress 610 acting between the first member 611 and the second member 612. An adhesive is applied to the contact surface between the first member 611 and the second member 612, and the adhesion in this case is about 400 (relative value) when the stress 600 is 1000. In the case of an eyelash extension, the finger exerts this tensile shear stress 610.

  FIG. 12 (c) shows the split stress 620 acting between the first member 621 and the second member 622. An adhesive is applied to the contact surface between the first member 621 and the second member 622, and the adhesive strength in this case is about 100 (relative value). 12 (d) shows a peeling stress 630 acting between the first member 631 and the second member 632. FIG. An adhesive is applied to the contact surface between the first member 631 and the second member 632 and the adhesive strength in this case is about 1 to 25 (relative value). In the case of eyelash extensions, most of them are detached by this peeling force. In addition, this adhesive force is estimated and calculated from the approximate theoretical value of the glue for eyelash extensions.

  The inventor of the present invention examined a method for improving the durability further while using the flat eyelash extension 100, and as a result, a mounting method (sandwich method) for sandwiching the flat eyelash 50 from above and below two flat eyelash extensions 100 I created it. In the case of the flat eyelash extension 100, since the thickness is thin as compared with the circular eyelash extension, even if the ground eyelash 50 is sandwiched vertically, it does not give much discomfort. Then, by bonding the two flat eyelash extensions 100 to the ground eyelashes 50, the bonding surface by the glue 20 can be increased, and the durability can be improved. In addition, by attaching two flat eyelash extensions 100 to the top and bottom of one earth eyelash 50, one of the two leaves remains even if it is dislodged, so the time period for which the appearance after installation is beautiful can be increased. .

  FIG. 13 is a schematic view (perspective view) showing the configuration of the sandwich type eyelash extension structure 100W in the present embodiment. FIG. 14 is a side view showing the configuration of the eyelash extension structure 100W. In addition, in order to give priority to ease of understanding, the correspondence (shape, size, etc.) between the structure (perspective view) of FIG. 13 and the structure (side view) of FIG. 14 is not the same.

  The eyelash extension structure 100W of the present embodiment has a structure in which flat eyelash extensions 100A and 100B are mounted on the upper and lower sides of a ground eyelash 50. The flat eyelash extension 100A is bonded to the upper side of the ground eyelash 50 by glue 20, while the flat eyelash extension 100B is bonded to the lower side of the ground eyelash 50 by glue 20. Here, “upper side” and “lower side” mean a direction along the vertical direction 90 when the user stands upright and the eyeball is directed in the horizontal direction 91, and when the user sleeps ( Or, when it is slanted, it changes according to it.

  In the configuration of the present embodiment, the flat eyelash extensions 100A and 100B are attached to the upper and lower sides of the ground eyelash 50, and not attached to the side face of the ground eyelash 50. In addition, although it does not prohibit mounting | wearing with the side of the ground eyelash 50, mounting | wearing with the upper and lower sides of the ground eyelash 50 is preferable. Further, the end portions (root portions) 15 of the flat eyelash extensions 100A and 100B are attached to the same portion (upper and lower surfaces of the same portion) in the vertical direction of the ground eyelash 50. Although it is possible to attach to different sites, it is preferable to attach to the same site in the vertical direction of the ground eyelashes 50 in consideration of ease of adhesion and adhesive strength (and appearance) of the glue 20. In the example shown in FIG. 13 and FIG. 14, the flat eyelash extension 100A is located immediately above the ground eyelash 50 and the flat eyelash extension 100B is located directly below the ground eyelash 50. However, since the eyelash extensions 100A and 100B are attached by the operator's hand, their positions may be slightly shifted.

  In the illustrated example, the thickness of the ground eyelash (human eyelash) 50 is about 0.05 mm, and the thickness of the flat eyelash extension 100 is 0.1 mm or more. In the case of the round eyelash extension 1000 as shown in FIG. 1, since the thickness of the root portion 115 is large, the attachment with a glue that is weak to peeling stress is often detached by the hook of a finger or a towel. In addition, the use of the thin eyelash extension 1000 of the root portion 115 with few hooks causes problems such as a decrease in the adhesive surface and a decrease in durability, and that the appearance does not have a voluminous feel. In the case of the eyelash extension structure 100 W using the flat eyelash extension 100 of the present embodiment, the thickness of the root portion 15 of the flat eyelash extension 100 (artificial eyelash main body 10) is thin, and the artificial eyelash main body 10 is also Because it is softer compared to the shape, it is possible to suppress the decrease in persistence with respect to the force (500 and 550 in FIG. 11) applied to the eyelash extension 100. In addition to that, since it has a sandwich structure, the adhesive area of the glue 20 at the root portion 15 is larger than that of the structure shown in FIG. ing. Furthermore, since the lower flat eyelash extension 100B is attached, the force 550 for peeling off as shown in FIG. 11 is not directly applied to the upper flat eyelash extension 100A, but the lower flat eyelash extension Since it is added to the extension 100 B, it works to compress the lower flat eyelash extension 100 B toward the ground eyelash 50. Therefore, in the case of the eyelash extension structure 100W of the present embodiment, the bonding strength and durability become greater than that of the structure shown in FIG.

  Further, since the eyelash extension structure 100C according to the flat eyelash extensions 100A and B shown in FIG. 13 is mounted in such a manner that the tip end (hair tip) 11 is separated, a sense of volume appears well. In particular, even if the number of eyelashes 50 is small, many eyelash extensions 100 (A and B) can be attached, and the sense of volume can be greatly increased.

  Furthermore, according to the configuration (100 W) of the present embodiment, since the adhesive strength / persistence is improved, even when using a hypoallergenic type glue 20 whose adhesive strength is weaker than that of the high stimulation type, It can exert its long-term sustainability. In the case of adhesion on one side with the round eyelash extension 1000, it has become less than half after 20 to 30 days, but in the configuration of the present embodiment, the durability is 30 to 40 days (or more) Can be stretched.

  The eyelash extension structure 100W of this embodiment can be modified as shown in FIG. In the eyelash extension structure 100W shown in FIG. 15, the tips 11 of the flat eyelash extensions 100A and 100B are configured to close (or stick to each other). According to the illustrated configuration, the flat eyelash extensions 100A and 100B with curls 10c stronger (or weaker) than the false eyelashes 50 sandwiching the false eyelashes 50 with the false eyelashes 50, even if the false eyelashes are not applied to the false eyelashes 50 50 curls can be made strong (or weak). That is, adjusting the curl of the ground eyelash 50 by attaching the above and below the ground eyelash 50 by selecting the flat eyelash extensions 100A and 100B having the desired curl 10c without perming the ground eyelash 50. Can.

  In addition, in the case of the structure 100W in FIG. 15, the gap between the flat eyelash extension 100A and 100B and the ground eyelash 50 is small (or substantially zero), so it resists the peeling off force 550 as shown in FIG. Adhesion is stronger, and the durability is improved. Also, if you want to lengthen the short eyelashes 50, it is difficult to obtain an adhesive surface, and therefore the persistence tends to be reduced, but in this structure, the flat eyelashes 50 are flat to cover almost (or completely) Since the eyelash extensions 100A and 100B are mounted, even with a short eyelash 50, it is possible to prolong the durability.

  In the eyelash extension structure 100W shown in FIG. 13 (FIG. 14) and FIG. 15, the upper and lower flat eyelash extensions 100A and 100B may have the same length or different lengths. It is also good. The upper and lower flat eyelash extensions 100A and 100B may have the same curl (10c) or different curls (10c). Furthermore, the upper and lower flat eyelash extensions 100A and 100B may be of the same nature (thickness, material, color, characteristics, etc.) or may be different.

  FIG. 16 shows a further modification of the eyelash extension structure 100W. In the eyelash extension structure 100W shown in FIG. 16, the upper flat eyelash extension 100A (here, 100A1 or 100A2) uses a strong curl (10c). The lower upper flat eyelash extension 100A uses a weak curl (10c). Thus, by changing the curl (10c) of the upper and lower flat eyelash extensions 100A and 100B, the impression of the appearance can be largely changed.

  Further, as shown in Fig. 16, the upper flat eyelash extension 100A may have a plurality of steps (here, two steps of 100A1 or 100A2). In addition, if there is a desired user, it is possible to make the lower flat eyelash extension 100B into a plurality of stages (e.g., two stages).

  Furthermore, the eyelash extension structure 100W of the present embodiment may be modified as shown in FIGS. 17A and 17B. 17A and 17B are a schematic view (perspective view) and a top view showing a modified example of the sandwich type eyelash extension structure 100W in the present embodiment. It should be noted that the correspondence (shape, size, etc.) between the structure of FIG. 17A (perspective view) and the structure of FIG. 17B (top view) is not completely the same in order to prioritize the ease of understanding. .

  In the eyelash extension structure 100W shown in FIGS. 17A and 17B, the tips (hair ends) 11 of the flat eyelash extensions 100A and 100B attached to the ground eyelash 50 are from the tip 51 (or the extension direction) of the ground eyelash 50. It is arranged to shift. The upper flat eyelash extension 100A and the lower flat eyelash extension 100B are not on the same side. In the illustrated example, the upper flat eyelash extension 100A extends to the left, and the lower flat eyelash extension 100B is bonded by a glue 20 so as to extend to the right. By doing so, it is possible to change the impression of the appearance by making the hair tips look like a plurality of them in one ground eyelash 50.

  The eyelash extension structure 100W shown in FIGS. 18A and 18B is a modification of the structure of FIGS. 17A and 17B. In the eyelash extension structure 100W shown in FIG. 18A and FIG. 18B, different upper flat eyelash extensions 100A and lower flat eyelash extensions 100B are used. In the illustrated example, the short artificial eyelash main body 10 (100S) is used as the lower flat eyelash extension 100B. In addition, not only the length but also thickness and curl may be changed. Further, which of the upper and lower flat eyelash extensions should be changed may be determined according to the user's (55) 's request.

  Further, in the modified example 100W shown in FIG. 19, the flat eyelash extension 100C having a different color is stacked on the upper flat eyelash extension 100A. Furthermore, in the modified example 100W shown in FIG. 20, the lower flat eyelash extension 100B is changed to a short one (100S). Thus, various variations can be constructed, and according to the eyelash extension structure 100W of this embodiment, the decoration of the eyelash extension of various impressions is performed according to the request of the user (55). can do.

  In the case of the eyelash extension structure 100W of the present embodiment, the glue (adhesive) 20 has poor wettability to the artificial eyelash main body 10 (mainly fibers made of PBT), and often tends to repel. Therefore, as shown in FIG. 21, the contact surface of the lower surface 10a (“10a-2” in FIG. 9) of the upper flat eyelash extension 100A and the ground eyelash 50, and the upper surface 10a of the lower flat eyelash extension 100B (FIG. A glue 20 is provided to cover between “10a-1” in 9 and the contact surface of the ground eyelash 50 and also to cover their side surfaces 10b (“10b-1”, “10b-2” in FIG. 9). Is preferably applied.

  FIG. 23 is a cross-sectional view (schematic view) of the root 15 region in the eyelash extension structure 100W shown in FIG. 22; In the example shown in FIG. 22, the glue 20 is formed to cover the entire contact surface (wide surface 10a) and the side surface 10b of the flat eyelash extensions 100A and 100B, as well as the opposite wide surface 10a. Of course, even if the glue 20 is not applied (and cured) in such a form to cover the whole, the glue 20 can be applied centering on the contact surface with the ground eyelash 50, but in order to increase the sustainability more As shown in FIG. 22, it is possible to select a fixing method such as covering the whole with glue 20.

  FIG. 23 shows that each of the upper eyelashes 50 has the eyelash extension structure 100W formed. As shown in FIG. 23, a number of extensions 100 are attached to the upper eyelash 50. It is preferable for the user (user) 55 that the eyelash extension 100 be attached to the eyelash 50 for as long as possible in such a state. And with the eyelash extension structure 100W using the flat eyelash extension 100 (100A, 100B, or 100S, 100C) of the present embodiment, it is possible to provide one that exhibits long-lasting durability.

  According to the method of attaching the eyelash extension 100 of the present embodiment (or the method of manufacturing the eyelash extension structure 100W), the cross-sectional shape of the artificial eyelash main body 10 constituting the eyelash extension 100 (100A, 100B) has a flat shape. And the artificial eyelash body 10 having the flat shape is adhered to both the upper side and the lower side of the ground eyelash 50. Therefore, the weight (mass) of the eyelash extension 100 (100A, 100B) can be made light (for example, half or less) by the artificial eyelash body portion 10 having a flat shape, and the wearing comfort is achieved. By bonding the ground eyelashes 50 from above and below in a sandwich structure, the durability of the eyelash extension 100 (artificial eyelash main body 10) can be improved.

  Note that the user (wearer) 55 prefers to face upward rather than downward in order to make the eyelashes extend the eyes with the eyelash extension 100. In order to maintain the upward state for a long time, the eyelash extension 100 of the present embodiment constitutes the artificial eyelash main body 10 not from human hair or animal hair but from synthetic fiber (fiber made of resin), and the artificial eyelash main body Preferably, 10 is heated to store the curled shape. Here, when human hair or animal hair is a natural material, and the shape (curved shape) is changed only by heating, the curl becomes loose immediately due to water absorption by water or hot water and returns to straight (straight hair) It will In addition, it is desirable for the eyelash extension material to be uniform in length, shape and color and luster, but human hair and animal hair are natural materials, so it is difficult to find such uniformity, and in fact If level uniformity is required, the manufacturing cost is increased, and it is not preferable to perform treatment with non-uniform eyelash extension materials because the operation skill of the beautician becomes sophisticated. Furthermore, consumers sometimes do not want such uneven eyelash extension materials, and natural eyelash extensions are also difficult in terms of hygiene, and when the preparation is not sufficient, the eyes Care should be taken as it may increase the risk of eye disease.

  Next, a method of manufacturing the eyelash extension 100 of the present embodiment will be described with reference to FIGS. 24 to 29. FIG. 24 is a flowchart for explaining the manufacturing method of the present embodiment.

  As shown in FIG. 24, in the case of manufacturing the eyelash extension, first, a resin for eyelash extension (polybutylene terephthalate: PBT) is prepared (step S110). Next, the resin (PBT) is extruded from a mold for producing a fiber for eyelash extension to produce a fiber (step S120). Thereafter, the fiber (fiber for eyelash extension) is cut into a predetermined length (length for easy processing of the eyelash extension) (step S130).

  In the present embodiment, the extrusion port (opening) of the mold of step S110 is flat. That is, the opening of the mold of the present embodiment is a flat opening having a dimension of half or less of the vertical dimension (T) with respect to the width dimension (W). Thus, it is possible to obtain a flat-shaped fiber for eyelash extension. Further, in step S110, after using a mold having a circular (or substantially circular) opening, a fiber for eyelash extension for circular shape is produced, and then the fiber for eyelash extension is processed to form a flat eyelash extension It is also possible to obtain an eyeglass (or an artificial eyelash body with a predetermined length). Specifically, by removing (cutting, polishing, etc.) the upper surface / lower surface of the circular shape eyelash extension fiber, it can be processed into a flat shape eyelash extension fiber.

  Next, the tip of the fiber is dipped in a medicine in a state of bundling the fibers of the predetermined length, thereby dissolving a part of the fiber to produce the tip of the eyelash extension (step S140). FIG. 25 shows an artificial eyelash main body in which a tip end portion is formed by impregnation with a drug in a state where fibers 3000 of a predetermined length are bundled by a band 3100.

  Next, the artificial eyelashes main body 3000 formed with its tip is aligned on a flat plate (step S150). In FIG. 26, the artificial eyelash main body 3000 is placed on the lithographic plate 3200, and the weight 3300 is placed on the artificial eyelash main body 3000 to align the artificial eyelash main body 3000. As shown in FIG. 26, with the tip 3111 of the artificial eyelash main body 3000 aligned (with the tip 3111 as a reference), the end 3115 B may not have the same length. I have to.

  Next, as shown in FIG. 27, the tape 3400 is attached in a state in which the end portions 3111 of the artificial eyelashes main body 3000 are aligned, and fixed in a state in which the artificial eyelashes main body 3000 is aligned (also step S150). Next, as shown in FIG. 28, the root (end 3115 B) of the artificial eyelash main body 3000 is cut cleanly to make the length of the eyelash extension product (defined in the unit of 1 mm). The artificial eyelash main body 3000 is obtained (step S155).

Thereafter, the artificial eyelash main body 3000 having a predetermined length is subjected to curling with a predetermined curvature (step S160) to produce the eyelash extension 100 having the eyelash shape. The curled eyelash extension 100 is shown in FIGS. 29 (a) to (d).

  As shown in FIGS. 29 (a) to 29 (d), the eyelash extension 100 of this embodiment can be formed into various curled shapes. In FIGS. 29 (a) to (d), I curls, J curls, C curls and D curls are shown, respectively, but CC curls, SC curls, and other curls (MIX) are also shown. There are also curls, SSC curls, L curls, etc.) eyelash extensions 100.

  The eyelash extension 100A shown in FIG. 29 (a) is an I curl eyelash extension. I Curl Eyelash Extension 100A is a curl-free eyelash extension that is suitable for people who do not want to be very flashy and want a natural finish. In particular, the eyelashes 55 originally grow upward, and are directed toward those who do not need the eyelash curlers.

  The eyelash extension 100B shown in FIG. 29 (b) is a J curl eyelash extension. J Curl's Eyelash Extension 100B is a gentle, natural curled eyelash extension that is suitable for people who want to make it look like their own eyelash. It is a curl that looks good on the face of a Japanese, and when you are blind, you can produce the most beautiful eyes. In particular, the eyelashes are directed to those who are level with the ground, and the cool eyes that look up from the front and the tips of the hairs are too high are directed to the person who likes them.

  The eyelash extension 100C shown in FIG. 29C is a C curl eyelash extension. C curl eyelash extension 100C is a eyelash extension with a curl that looks like a burger. Seen from the front, you can see the hair tip moderately, so that you can make your eyes look bigger, and the curl can make the eyes lovely. In particular, the eyelashes are originally directed slightly downward, and the cute eyes look like they look from the front, because the hair tips look up.

  The eyelash extension 100D shown in FIG. 29 (d) is a D curl eyelash extension. The D curl eyelash extension 100D is an eyelash extension having a curl that is more rounded than the C curl. The image with a strong Buhler can produce a dazzling look that looks like a doll, so you can make your eyes look bigger. In particular, the eyelashes are originally directed downwards, and when viewed from the front, the tips of the hairs are raised directly above, so the more cute and round eyes are directed to the user.

  In order to curl the artificial eyelashes main body 10 (step S160), the artificial eyelashes main body 10 (refer to the artificial eyelashes main body 3000 shown in FIG. 18) aligned with high accuracy based on the tip 11 is heated. The shape of the portion 10 is curved, and the shape is stored (fixed).

  For example, the artificial eyelash main body 10 is pressed against a mold so that the artificial eyelash main body 10 has a curled shape (see, for example, FIGS. 29A to 29D), and heating and cooling are performed. Form a curl of shape. Specifically, a curl (10c) is formed on the artificial eyelash body portion 10 by winding the artificial eyelash main body portion 10 with a tape or the like around a cylindrical metal pipe (aluminum pipe) or a glass rod and heating for a predetermined time. The strength of the curl is adjusted by decreasing or increasing the diameter of the winding pipe. The conditions change depending on the thickness and material of the artificial eyelash body 10, but the heating temperature is, for example, 160 to 190 ° C., the heating time is, for example, 3 to 30 minutes, and then the cooling time is 3 to 30 minutes. Depending on the thickness of the bristles, the same operation may be repeated several times by adjusting the heating and cooling times. This is an exemplification, and suitable ones may be adopted as appropriate depending on the materials and conditions to be used or the required properties.

  In addition, it is difficult to form the curl as described above uniformly and easily with a natural material. In order to curl with a natural material, due to the structure of the hair, its shape can not be maintained unless its physical properties are changed with an ammonia-based drug (a so-called "perm" is applied). If you are merely heating to reduce the moisture and maintaining the shape without soaking it (so-called curl formation by the drier), the curl will become loose immediately in summer or rainy days when the humidity is high.

  Then, by attaching the eyelash extension 100 having a uniform shape (length, cross-sectional shape, curl) to the backing sheet 150 (step S170), the product shown in FIG. 30 (container 200 containing the eyelash extension 100) can be obtained. . The container 200 shown in FIG. 30 is composed of the eyelash extension 100 closely aligned and pasted on a backing 150 and a container main body 215 for housing the backing 150. In addition, when making it in the state of being separated (for example, when putting in the case 2000 or a bag shown in FIG. 3) without sticking on the backing sheet 150, when producing the eyelash extension 100 in the curling step (S160), remove it from the tape 3400 , You may pack cases (packing).

  More specifically, in order to produce the product shown in FIG. 30, a block of eyelashes extension 100 with the desired curl (10c) is formed (the eyelashes extension 100 aligned in a row) is applied to a backing sheet and the eyelashes extension is made. Fix 100 blocks. Specifically, the block of the eyelash extension 100 is attached to a backing sheet 150 stored in a case 200 (case for eyelash extension according to the present embodiment) as shown in FIG. As shown in FIG. 31, an adhesive layer 155 is formed on the surface of the backing sheet 150, and the end portion 15 of the eyelash extension 100 is affixed to the adhesive layer 155 by fixing. In a state of being fixed on the backing sheet 150, the tip end 11 (pointed tip) of the eyelash extension 100 maintains a state of being aligned with high accuracy with respect to the reference line 130. In the present embodiment, the eyelash extension 100 is aligned with an accuracy of, for example, ± 0.5 mm (preferably ± 0.2 mm) with respect to the reference line 130.

  The case 200 of the present embodiment includes a mount 150 to which the eyelash extension 100 is to be attached, and a container main body 215 for storing the mount 150. In the case 200 shown in FIG. 32, a mount stopper 211 for holding a mount 150 is provided. The backing sheet 150 is a member made of paper (or resin), and the container body 215 is made of resin (in this example, transparent resin). The case 200 may be a combination of a container portion (210, 215B, 215B) connected in a hinge format as shown in FIG. 32, and a mount 150 on which the eyelash extension 100 is attached.

  FIG. 32 shows the structure when the case 200 of this embodiment is opened. The container main body 215 of the case 200 is composed of the first cover 215A and the second cover 215B, and when each is closed in order, the form of the container main body 215 shown in FIG. 30 can be obtained. . The first cover 215A and the second cover 215B are connected to each other by the pedestal 210, and the mount 150 is disposed on the pedestal 210. The mount 150 is fixed by the mount stopper 211 so as not to move as much as possible in the case 200. That is, in the state shown in FIG. 19, the base sheet 150 to which the eyelash extension 100 (a plurality of rows of a plurality of eyelash extension blocks are attached) can be stored in the pedestal portion 210 of the case 200.

  It is the alignment step (S150) of the artificial eyelash main part that takes a lot of trouble in this series of manufacturing steps. At this stage of the alignment process, if the artificial eyelashes (3000) are not properly aligned (ie, the tip 3111 has an accuracy of ± 0.2 mm), then there is a high possibility of defects. I will. In addition, in this alignment process, it is difficult to automate the machine, and it is necessary to rely on a human hand, which requires time and cost, and requires the skill of the worker to be proficient. This process becomes a bottleneck, making it difficult to shorten the delivery time of manufacturing, and to make it even more difficult to reduce costs.

In addition, in the case of the structure (shape) of the eyelash extension 100 according to the present embodiment, the artificial eyelash main body 10 is not circular but has a flat shape as shown in FIG. 6 and FIG. There is also a restriction that the portion 10 can not be rolled and the step of aligning the artificial eyelash body (S150) can not be performed. That is, in the case of a circular artificial eyelash main body, a curling process (
Since the shape is the same even if it is rotated before S160), the alignment operation (S150) can be performed by rotating the artificial eyelash main body (rotation about the axial direction). However, since the artificial eyelash body portion 10 of this embodiment has a flat shape, it can not be rotated because the vertical and horizontal shapes are different. Therefore, it takes time by the alignment step (S150) of the artificial eyelash main body.

  Under such circumstances, the inventor of the present application worked on the improvement of the alignment step (S150) of the artificial eyelash main body, considering that the artificial eyelash main body 10 has a flat shape. Certainly, if the artificial eyelash main body 10 has a flat shape, it is difficult to mix and rotate the vertical and horizontal directions, but the flat horizontal surface (that is, the wide surface 10a (10a-1, 10a- 2) is easier to stabilize than longitudinal (narrow surface 10b), so in the state shown in Fig. 26, the flat artificial eyelash body (3000) is not rotated but aligned By chance, I found that it was easier to align than rotating the artificial artificial eyelash body (3000) and aligning it by tapping it several times with the weight 3300 loaded.

  When aligning the circular artificial eyelashes main body (3000), in the state shown in FIG. 26, a large number of artificial eyelashes main body (3000) are stacked (for example, a stack of 5 cm or more) to perform the alignment operation However, in the case of the flat-shaped artificial eyelash body portion (3000, 10) of the present embodiment, the alignment operation does not work well when stacked so high. A flat-shaped artificial eyelash body (3000, 10) is made into a single layer, and the weight 3300 is placed (with the hand of a person) and vibration is applied with the ton- ton, and alignment can be performed well. Although a single layer is ideal, it is also possible to arrange the arrangement by the weight 3300 in a state in which flat artificial eyelashes (3000, 10) are stacked at a height of 1 cm or less. Although 2 cm or less may work well, it is preferable not to stack too high. In addition, by adding vibrations and vibrations, it is possible to carry out an alignment operation that can properly align the arrangement of the artificial eyelashes (3000, 10), which facilitates the introduction of mechanization as well as the operation of human hands. Become.

  In addition to the blocks 170 shown in FIGS. 30 and 31, it is also possible to construct a block 150 as shown in FIG. In the block 150 shown in FIG. 33, the artificial eyelash body portions 10 of this embodiment are not independent one by one, but the end portions (root portions) 15 of the artificial eyelash main body portions 10 adjacent to each other are adhered It has a structure. That is, in the block 170 shown in FIG. 33, the end portions 15 of the artificial eyelashes main body portion 10 are adhered to each other (for example, fusion bonding, pressure bonding, adhesion fixing with an adhesive / adhesive agent, etc.). Therefore, the artificial eyelash main body 10 according to this embodiment can be removed one by one with the artificial eyelash main body 10 by a tweezers or a hand. Then, the artificial eyelash body 10 thus removed can be attached to the eyelash 50.

  Furthermore, in the eyelash extension 100 of the present embodiment, the plurality of artificial eyelash main portions 10 are formed into uniform curves (curved portions) 10c, but according to the method of the present embodiment, the curve shape can be controlled with high accuracy. You may form the block 170 containing several artificial eyelash main-body parts 10 including curve shape (curved part 10c). In the configuration of the present embodiment, the artificial eyelash main body 10 has a flat shape (10a, 10b), and as a result, the curl forming accuracy is excellent, so a block 150 including a plurality of types of curls is also manufactured. Can.

  In addition, in the eyelash extension 100 of the embodiment described above, although the resin 12 constituting the artificial eyelash main body 10 is exclusively polybutylene terephthalate (PBT) (for example, 95% or more), changes can be made thereto . For example, the resin 12 constituting the artificial eyelash main body 10 can be composed of polybutylene terephthalate (PBT) and a low temperature modified resin material which is modified at a lower temperature than polybutylene terephthalate. Here, when 50% by mass or more of the low-temperature modified resin material is contained when the entire resin is 100% by mass, the artificial eyelash main body 10 (or the curved portion 10c) in which the curved portion 10c is once formed. The artificial eyelash body portion 10) in which is not formed can be changed by the eyelash curler (viewer) to the desired curvature of the curl (second curl). Low temperature modified resin materials that are modified at lower temperatures than polybutylene terephthalate are, for example, nylon, polyvinyl chloride, and polytrimethylene terephthalate (PTT). One of these materials (low temperature modified resin material) may be used, or a mixture of several types of materials (low temperature modified resin material) may be used. The temperature characteristics of a low temperature modified resin material modified at lower temperatures than polybutylene terephthalate can be determined, for example, by the glass transition point (glass transition point) of the polymer, but physical and chemical properties are also important. But, with that, the temperature of whether it denatures by the eyelash curler becomes the point. If 50% by mass or more of the low temperature modified resin material is contained, the ratio may be suitably selected.

  In a preferred configuration of the present embodiment, polytrimethylene terephthalate (PTT) can be used as the low temperature modified resin material, and when the low temperature modified resin material is polytrimethylene terephthalate (PTT), polytrimethylene is used. About 70% by mass of terephthalate (PTT) may be included. Although 10% by mass of polytrimethylene terephthalate (PTT) can be used, it is more preferable than all the resin 12 to be polytrimethylene terephthalate (PTT) in consideration of characteristics required for shape stability and eyelash extension It may be mixed with polyethylene terephthalate (PET). In addition, although the low-temperature modified resin material is 50% by mass or more, the proportion of the low-temperature-modified resin material is 30% by mass or more depending on the material used for the low-temperature-modified resin material or the characteristics required for eyelash extension It does not matter if it is a range.

  When the eyelash extension 100 (artificial eyelash main body 10) is exclusively made of polybutylene terephthalate (PBT), the artificial eyelash main body 10 may have a curved portion (curl) 10c at a temperature of around 180 ° C. Heating for 120 minutes is performed according to the thickness of the hair. This is the same even if the eyelash extension 100 is circular. After the curling heat treatment, it is difficult to change the curl again, and it is difficult to control the curl shape with high accuracy even if the second curling is performed. In addition, when the eyelash extension 100 (artificial eyelash main body 10) is exclusively made of polybutylene terephthalate (PBT), the artificial eyelash may be generated by the eyelash hot curler (viewer) that curls at a relatively low temperature (about 120 °). The curved portion (curl) 10 c can not be applied to the main body portion 10. Here, according to the configuration of the modified example of the present embodiment, since the low temperature modified resin material is contained together with the polybutylene terephthalate (PBT) in the resin 12 constituting the artificial eyelash main body 10, the relatively low temperature ( Even with a hot curler for eyelashes (viewer) that produces curls at around 120 °, the curvature of the curl of the artificial eyelash body 10 can be changed.

  More specifically, if the resin 12 constituting the artificial eyelash body 10 contains 50% or more of the low-temperature modified resin material, the temperature of the eyelash curler (for example, 120 ° C. or less (or 130 ° C. or less)) Using a heating-type eyelash curler (or a pressure-type eyelash curler), weak curled eyelashes (see, for example, FIG. 29 (a)), slightly strong eyelashes (see, for example, FIG. 29 (b)), slightly strong eyelashes It can be adjusted to an extra (see, for example, FIG. 29 (c)) and a very strong eyelash extension (see, for example, FIG. 29 (d)). As a result, it is not necessary to prepare, as a stock, the eyelashes extensions according to the degree of curl (for example, the eyelashes extensions 100A to 100D in FIGS. 29A to 29D). Also, not only can the user attach a predetermined curled eyelash extension that is a ready-made product, but also allow the user to wear an eyelash extension with a curl that matches the user's detailed requirements (hobby, preferences). Become.

  When preparing a large number of curled eyelash extensions, it is necessary to keep unpopular products depending on the product as inventory, causing variations in shape within half a year to a year, or breeding of bacteria to cause mold Since the possibility of growing is increased, it is often disposed of in anticipation of it. In addition, even if the treatment is performed after mutually confirming the intention between the eyelash extension technician (practitioner) and the user (consumer), in rare cases, the user may not like the curl angle after wearing It could have happened. According to the modified eyelash extension of this embodiment, a curve having an arbitrary angle (curvature) can be attached to the artificial eyelash main body 10 by the hot curler (viewer) for eyelashes, so there is a problem of having a large variety of stock. Can be relaxed, and an eyelash extension having a curl desired by the user can be realized.

  In the case of the eyelash extension according to the modification of this embodiment, since the low temperature modified resin material is included in the resin 12 constituting the artificial eyelash main body 10 (at least 40%, typically 50% or more), In the curling step (step S160 in FIG. 24), the hair tips (tip portions 11) are thinner than the root portions (end portions 15), and thus may be melted. The same is true for the circular artificial eyelash main body 10, but the flat artificial eyelash main body 10 is more likely to melt the tip of the hair. Therefore, if curling is performed by winding the artificial eyelash body 10 (3000) around a metal pipe (for example, an aluminum pipe) with a heating source, the temperature of the tip portion (hair tip) 11 is lowered It is preferable to perform various temperature control. When performing such temperature control, it is preferable to adjust the thermal conductivity (or resistivity) of the metal pipe (or the heater applied thereto). Furthermore, since the portion of the tip (hair tip) 11 may melt, it is also possible to cut the melted tip (or a tip that may be melted) and align the tip 11 cleanly. it can.

Second Embodiment
The following modifications can be made to the eyelash extension 100 of the embodiment described above. In the alignment step (S150 in FIG. 24) of the artificial eyelash main body 10 (3000) of the present embodiment, there are also difficulties in the alignment due to static electricity of the artificial eyelash main body 10 (3000) as well as the alignment difficulty due to the flat shape. Do. That is, since the artificial eyelash body 10 (3000) is made of a resin (for example, PBT) and the resin is a dielectric (insulating material), it tends to have static electricity. If a thin resin fiber like an eyelash (artificial eyelash body 3000) has static electricity, each will stick with static electricity, and it will not be in a clean, easy alignment state. If the influence of static electricity can be mitigated, it is likely that it will be easier to put the artificial eyelashes 3000 in a clean alignment (uniform alignment) as shown in FIG. Therefore, along with the difficulty in alignment due to the flat shape, the difficulty in alignment due to static electricity can be resolved.

  However, since the artificial eyelash main body 3000 is made of resin (made of PBT), it is a physical property that the resin (dielectric) has static electricity, so the resin constituting the artificial eyelash main body 3000 will have static electricity It can not be helped. In addition, since the resin (PBT) is a hydrophobic material, even if it is sprayed with something like misting to prevent static electricity, it is possible to use resin only by attaching water droplets (atomized particles) to the surface of the resin. In addition to being sucked by the inside and attached by water, the process of drying is also required, and the number of manufacturing steps is increased. That is, it adversely affects the alignment operation.

  The inventor of the present invention first made an idea to try to adjust the generation of static electricity by raising the humidity of the work space in the alignment step (S150), but in fact, such a thing can not be done in a wide factory. However, if such a thing is done, the manufacturing cost of the eyelash extension will rise, which is not preferable. Further, even if water is introduced into the resin (PBT), the hydrophobic resin and water do not mix well, so it is not preferable as a material for an artificial eyelash main body (eyelash extension).

  Under such circumstances, it is possible to adjust or control the moisture content of the artificial eyelash main body by kneading a hydrophilic material (water-containing material) with the material (resin material) constituting the artificial eyelash main body (3000) When I thought of an idea and tried it, the alignment work of the artificial eyelashes whose moisture content was adjusted could be performed well by the effect of suppressing static electricity. Furthermore, when the step (S160) of curling the artificial eyelash body (3000) whose moisture content has been adjusted is performed, the duration of the curl (curvature) of the artificial eyelash body (eyelash extension) can be controlled. I also understood. Therefore, in addition to the feature of the curl shape control by the flat shape of the artificial eyelash body portion 10 in the embodiment described above, the characteristics of the curl can be further improved.

  FIG. 34 shows the structure of the eyelash extension 101 of the second embodiment. 35 and 36 are a cross-sectional view taken along the line A of FIG. 34 and an enlarged cross-sectional view of a portion B, respectively. Moreover, FIG. 37 is a flowchart for demonstrating the manufacturing method of the eyelash extension 101 of 2nd Embodiment.

  The eyelash extension 101 of the present embodiment (second embodiment) includes an artificial eyelash main body 10 having a tip 11 and an end 15, and the artificial eyelash main body 10 is made of a resin 12. In the configuration (101) of the present embodiment, the moisture content of the artificial eyelash body portion 10 is adjusted. By adjusting (increasing) the moisture content of the artificial eyelash main body 10, the generation of static electricity can be prevented / suppressed, and by adjusting the moisture content of the artificial eyelash main body 10 (specifically, By setting the upper limit, it is possible to control the persistence (duration) of the curl (curved portion 10c) of the artificial eyelash body portion 10.

  The moisture content (% by mass) of the artificial eyelash body portion 10 of the present embodiment is, for example, more than 0.1% and 10% or less. From the viewpoint of satisfying better prevention (prevention) of static electricity generation, the lower limit value (value serving as a reference value of “or more”) of the moisture content (mass%) of the artificial eyelash main body 10 is, for example, 0.2% or more Alternatively, it is preferably 0.3% or more. An example of the moisture content of the artificial eyelash body portion 10 of the present embodiment is 0.2% or more and 5% or less, or 0.2% or more and 1% or less, or 0.3% (± 0.1%) Or, 0.4% (± 0.1%), 0.5% (± 0.1%), 1.0% (± 0.1%) or 1.0% (± 0.5%) ). The measurement of the moisture content can be performed using a commercially available heat-drying moisture meter (for example, a device capable of measuring the moisture content of PET pellets). However, it does not exclude the official test method (heat drying method), near infrared spectroscopy, and other measurement methods of moisture content.

  The artificial eyelash body portion 10 of the present embodiment contains a component (30) for adjusting the moisture content. Further, since the resin (for example, PBT) constituting the artificial eyelash main body 10 is a hydrophobic material, it is difficult to knead water in the resin, and it is difficult to uniformly contain water. is there. In addition, if the resin contains water in a form separated from the resin instead of being impregnated with water, the water does not evaporate or does not evaporate from the artificial eyelash main body 10 containing water. In some cases, it is difficult to control the moisture content, and it becomes difficult to control the moisture content to a constant level. In the artificial eyelash main portion 10 of the present embodiment, a component for adjusting the water content (referred to as “water content adjustment component 30 or the like”) is blended in the resin 12.

  The moisture content adjusting component 30 of the present embodiment is a component capable of retaining water, and is preferably a component that is uniformly dispersed in the resin 12 when the component is kneaded into the resin 12. Such a moisture content adjusting component can be exposed on the surface 10 a of the artificial eyelash main body 10 but does not have to be completely uniformly dispersed, and the moisture content of the artificial eyelash main body 10 is adjusted (improved) If possible, they are present on the surface 10a (or 10b) of the artificial eyelash body 10 to prevent static electricity and not present (or density / concentration) in the central part (core) of the artificial eyelash main body 10 May be). The moisture content adjusting component does not have to be uniformly dispersed in the resin 12, but it is present at least on the surface (surface portion) 10a of the artificial eyelash main body 10 from the viewpoint of achieving the antistatic function. Is preferred.

  In the configuration of the present embodiment, the water content adjusting component is, for example, a naturally-occurring polymer component capable of holding water. Such naturally occurring macromolecular components may include proteins (in some cases also including peptides) or materials containing proteins, polysaccharides or materials containing polysaccharides, and among various proteins or polysaccharides, In addition to amino acids (or their derivatives), collagen, gelatin, hyaluronic acid, agar, alginic acid (or their derivatives), chitin, chitosan etc. It can be used. When a naturally-derived polymer component is used as the moisture content adjustment component, the user can feel at ease from the image of a natural material, but as the moisture content adjustment component, an artificial material capable of holding moisture (for example, (Hydrophilic / water-retaining artificial polymer material / hydrophilic polymer) can be used. It is also possible to use an inorganic material (for example, a hydrophilic inorganic material, a metal oxide material (metal oxide ion particles), a metal ion material (metal ion particles, etc.)) capable of retaining water. It is also possible to use combinations (mixtures) or derivatives of the above-mentioned materials (for example, esters, modified groups, salts etc.) or mixtures thereof In addition, artificial eyelashes 10 It is preferable that the water content adjusting component is in the form of particles, for example, having a particle size (average particle diameter) of about 30 μm or less, from the viewpoint of dispersing the water content adjusting component in the resin 12 of Preferably, the particle size is 20 μm or less (or 10 μm or less) and the particle size is as uniform as possible (the particle size distribution is clean), but in the particle form. Such figures it and particle size may be selected as preferred by eyelash Extended the manufacture / use, not intended to be limited to them.

  Next, with reference to FIG. 37, a method of manufacturing the eyelash extension 101 according to the embodiment of the present invention will be described.

  First, the step (S210) of adjusting the moisture content of the resin 12 is performed. The resin 12 is, for example, polybutylene terephthalate (PBT), polyester, acrylic, vinyl chloride, nylon, etc. as described above, and in the typical case of the present embodiment, the resin 12 is PBT, Resin may be used. Further, as described above, it is also possible to mix a low temperature modified resin material which is modified at a lower temperature than polybutylene terephthalate. Then, the moisture content adjustment component 30 (or moisture absorption / water absorption component) is added to the resin 12 (for example, PBT or the like) and kneaded. Alternatively, the resin 12 may be prepared in a state of being already kneaded. It is also possible to use the water content adjusting component 30 in a state in which water is contained in the water content adjusting component 30 or water is naturally absorbed.

  When polytrimethylene terephthalate (PTT) is included in the resin 12 constituting the artificial eyelash main body 10 (or when the artificial eyelash main body 10 is formed of polytrimethylene terephthalate (PTT)), You can get an advantage. As described below, first, polytrimethylene terephthalate (PTT) is, in the first place, artificial eyelash body portion 10 in comparison with polybutylene terephthalate (PBT) which is typically used as resin 12 constituting artificial eyelash body portion 10. In order to achieve this, there is a high technical barrier, and specifically, there is a problem that the cost is high and it can not be manufactured unless curl processing (high-temperature long-time heat treatment) is devised. Here, when polytrimethylene terephthalate (PTT) is used and the water content of the resin 12 is increased, the curing of the adhesive can be accelerated without decreasing the strength of the cyanoacrylate adhesive. Is obtained. And, it is possible to shorten the time until face washing and bathing after the treatment. In addition, the time when the person who receives the treatment feels stimulation is shortened, and the time when the technician who performs the treatment feels a pungent odor due to the steam until hardening is also shortened. Complete curing is accelerated and skin irritation by chemicals such as formaldehyde is reduced. Furthermore, the reduction of the stimulant also reduces the risk of developing contact irritations such as irritant contact dermatitis, allergic contact dermatitis, keratitis, conjunctivitis, eye congestion and the like. In addition, also in terms of production, when polytrimethylene terephthalate (PTT) is used, the curling time can be shortened compared to when polybutylene terephthalate (PBT) is used, and the production efficiency of the curling process (Productivity) can be improved.

  In the present embodiment, when the water content adjusting component 30 is 100 parts by mass of the resin (PBT) 12, for example, the compounding ratio (including the boundary value) is 0.01 parts by mass to 5 parts by mass. It is blended in 12. The mixing ratio of the moisture content adjusting component 30 is the water content of the artificial eyelash main body 10 in the step of aligning the artificial eyelash main body 10 (S250) and the step of curling the artificial eyelash main body 10 (S260) Determined according to the rate. Therefore, according to the desired moisture content as the target (target), and according to the type of moisture content adjustment component 30 used (or the amount of moisture contained in the moisture content adjustment component 30), appropriate value ( You should adopt ratio, mass). Since a large amount of water (moisture) may be retained even with a small amount of water content adjustment component 30, the proportion (mass% or mass proportion) of the water content adjustment component 30 is the proportion of water (water content) It does not necessarily become the value of the rate (%).

  In the configuration of the present embodiment, the blending ratio (mass%) of the water content adjusting component 30 to be contained in the artificial eyelash main body 10 (the total mass including the resin 12) is 10% or less (or 15% or less in some cases) It is less than 5% in consideration of practicality in actual products. If the proportion of the moisture content adjusting component 30 is too large, the physical properties of the mixture (the material in which the resin 12 and the moisture content adjusting component 30 are mixed) constituting the artificial eyelash main body 10 are changed as compared with those of the resin 12 alone. It is possible that the curve of the eyelash extension 101 can not be produced or the predetermined softness can not be produced. The blending ratio (mass%) of the moisture content adjusting component according to an example of the present embodiment is 2% or less, or about 1% or less (preferably, about 1%, or about 1%, for example, 1% ± 0) .3%, or 1% ± 0.5%, etc.). Also, in order to minimize changes in physical properties, the blending ratio may be determined in a range such as 0.5% ± 0.1%, with the upper limit being 1%. If the curve (curvature) of the artificial eyelash main body 10 can be taken out and other conditions (softness and the like) can be satisfied, the blending ratio of the moisture content adjusting component 30 is not limited to the above-mentioned numbers, and is suitably suitable It does not matter. In the present embodiment, the mass of the moisture content adjusting component 30 with respect to the total mass is represented by the compounding ratio in the artificial eyelash main body 10, but in some cases, the artificial eyelash main body 10 is not the whole standard but the resin 12 standard. If it is more convenient to determine the blending ratio, substitute the proportion of the mass of the moisture content adjusting component 30 (for example, 10 parts by mass or less (or 15 parts by mass or less)) with 100 parts by mass of the resin 12 I don't care.

  When coloring the eyelash extension 101 of this embodiment, coloring can be performed by adding a pigment to the resin 12 in the step of mixing the moisture content adjusting component 30 with the resin 12 (step S210). The coloring (or staining) of the resin 12 can be made black, for example, colors such as dark brown, purple, blue, pink, silver, green, light orange, light gold, red, wine red, white, yellow, etc. Can be The moisture content adjusting component 30 and the pigment (colorant) may be simultaneously mixed in the resin 12, or the pigment may be mixed in the resin 12 after the moisture content adjusting component 30 is introduced. Alternatively, the moisture content adjusting component 30 may be mixed with the resin 12 after the pigment is introduced. The white or transparent fiber (resin fiber) can also be dyed later.

  Next, the resin (water-containing resin) 12 containing the moisture content adjusting component is extruded from the mold (step S220). The mold is provided with an opening that defines the shape (cross-sectional shape) of the artificial eyelash body portion 10. In the present embodiment, a mold for defining an opening having a flat shape as shown in FIG. 25 is used. When the resin (resin mixture) 12 containing the moisture content adjusting component 30 is extruded from the mold, a fibrous material having the cross-sectional shape shown in FIG. 35 is obtained.

  Next, the extruded fibrous material is cut into a length that facilitates processing of the eyelash extension 100 (artificial eyelash main body 10) (step S230). That is, it is cut into a predetermined length corresponding to the eyelash extension 100. When cutting, a fibrous material may be cut by a cutter (cutting device) with a predetermined length. Thereafter, the distal end of the artificial eyelash main body 10 cut into the predetermined length (length corresponding to the eyelash extension 100) is attached to a drug to form the distal end 11 of the artificial eyelash main body 10 (step S240) . That is, by attaching a part (tip) of the artificial eyelash main body 10 to a drug that dissolves the resin 12, a part of the resin 12 is dissolved to narrow the diameter of the artificial eyelash main body 10 to form the tip 11 Do.

  Next, the artificial eyelash body 10 is aligned (step S250). Specifically, as shown in FIG. 26, an artificial eyelash main body 10 (3000) having a tip 11 (3111) is placed on a flat plate 3200, and then a weight (a paper-like device) 3300, The artificial eyelash main body 10 is aligned by suppressing the artificial eyelash main body 10 (3000).

  Here, since the water content (water content) of the artificial eyelash body portion 10 of the present embodiment is adjusted, the generation of static electricity is prevented (suppressed). In the case of a typical artificial eyelash main body 3000 (an artificial eyelash main body not containing a moisture content adjusting component), static electricity is generated in the typical artificial eyelash main body 3000. As a result, a plurality of light and thin artificial eyelashes 3000 come in close contact with each other due to the static electricity, and they can not be easily aligned. In addition, in order to prevent the generation of static electricity of a typical artificial eyelash main body 3000 (an artificial eyelash main body not containing the moisture content adjusting component 30), when water droplets are applied to the artificial eyelash main body 3000 by spraying or the like The light and thin artificial eyelash main unit 3000 becomes solid with water and can not be aligned.

  On the other hand, in the case of the artificial eyelash main body 10 of the present embodiment, since there is no generation of static electricity, the artificial eyelash main body 10 (3000) can be aligned easily and cleanly even with a light and thin artificial eyelash main body 10. be able to. When performing the alignment step of the artificial eyelash body 110 in which the moisture content is not controlled, this alignment step may be performed by a skilled worker, for example, 6 cm or more in 4 cm width x 8 cm width (in one example, 6 to 10 min) However, in the case of the alignment step (S250) of the artificial eyelash body portion 10 of the present embodiment, it can be performed, for example, in 3 minutes or less (2 to 3 minutes in one example) by a worker with the same skill. The work time can be reduced in the same way because even less skilled workers are not affected by static electricity. In addition, since the handling of the artificial eyelash main body 10 in the alignment step (S250) is simplified, the defective item occurrence rate of the artificial eyelash main body 10 can be reduced, that is, the yield can be improved.

  Align the alignment (alignment accuracy: within ± 0.2 mm) with reference to the pointed end 11 of the sharpened tip, and if the gap between the adjacent artificial eyelashes 10 is removed, the alignment (aligned The artificial eyelash body 10 block) is taped and fixed. Next, the root (end 15) of the artificial eyelash body 10 is cut. When the end 11 is melted, a process of cutting the end 11 may be added.

  Thereafter, the artificial eyelash body 10 is curled (step S260). This curling process is performed by heating the artificial eyelash main body 10 (3000) aligned with high accuracy based on the tip 11 to curve the shape of the artificial eyelash main body 10 and memorize (fix) the shape. . For example, the artificial eyelash main body 10 is pressed against a mold so that the artificial eyelash main body 10 has a curled shape (see, for example, FIGS. 16A to 16D), and heating and cooling are performed. Form a curl of shape. As described above, specifically, the artificial eyelash main body portion 10 is wound around a tubular metal pipe (aluminum pipe) or a glass rod with a tape or the like and heated for a certain period of time to curl the artificial eyelash main body portion 10 (10 c Form). The strength of the curl is adjusted by decreasing or increasing the diameter of the winding pipe. In addition, when the low temperature modified resin material is included in the resin 12, the artificial eyelash main body 10 (or the artificial eyelash main body 10 of the straight hair) of the curved portion 10c having a constant curvature is manufactured The curved portion 10c can also be formed by an eyelash curler.

  The value also changes depending on the thickness and moisture content of the artificial eyelash body 10, but the heating temperature is, for example, 160 to 190 ° C., the heating time is, for example, 3 to 30 minutes, and then the cooling time is 3 to 30 minutes. Depending on the thickness of the bristles, the same operation may be repeated several times by adjusting the heating and cooling times. Since the heating process is performed in the curling step (S260), it is necessary to keep in mind that when the water content adjusting component is displayed in mass%, the value may change if the total weight changes. For example, although the blending ratio (mass%) of the moisture content adjusting component immediately after the curling step (S260) is 0.01% to 5%, this is an example, and the materials, conditions, or necessity to be used Depending on the characteristics to be used, a suitable one may be adopted appropriately.

  Next, the block of the eyelash extension 101 having the desired curl (10c) (the lined-up eyelash extension 101) is attached to the backing sheet to fix the block of the eyelash extension 101 (step S270). This is similar to that shown in FIGS. 30 and 31 described above.

  The case 200 shown in FIGS. 30 and 32 has the following advantages as compared to the case 2000 shown in FIG. First, the case 2000 shown in FIG. 4 is fragile because it has a hinge structure portion, but the case 200 shown in FIG. 20 is structurally strong because there is no hinge structure portion, and the first cover 215A and Since the second cover 215B, the pedestal portion 210, and the mount stopper 211 can be manufactured by a series of members (resins), there is a merit also in terms of manufacturing. Further, in the case of the case 2000 shown in FIG. 4, when an impact is applied to the case 2000, the block 1500 of the eyelash extension 1000 which has been neatly aligned at the angle often collapses. In particular, when the container portion 2300 is made of a hard resin, an impact is easily transmitted to the eyelash extension 1000 and the alignment is likely to be broken. On the other hand, the case 200 shown in FIG. 32 (a series of continuous members consisting of the first cover 215A, the second cover 215B, the base portion 210 and the mount stopper 211) is made of soft resin (for example, PVC (polyvinyl chloride), PET (polyethylene terephthalate) And acrylic resin etc.), the impact is received entirely, and the alignment of the eyelash extension 101 (100) is less likely to break down. In addition to the fact that the alignment of the eyelash extensions 101 (100) is simplified by the manufacturing method of the present embodiment, if the case 200 of the present embodiment is used, the alignment is suppressed from being broken by an external impact. be able to. In addition, when it stores in the state of falling apart (for example, when putting in the case 2000 or a bag shown in FIG. 3) without sticking on a mount (for example, when putting in the case 2000 or a bag shown in FIG. You can make it and pack it in a case. Even in this case, it is possible to obtain the merits of the static electricity suppressing effect in the alignment step (S250 and S255) for properly aligning the lengths.

<Example>
Next, an experiment was conducted on the relationship between the moisture sensitivity in the artificial eyelash body 10, the alignment time, and the change in working efficiency with the sensation of sensation, and the results are shown in FIG. This experiment was performed as follows. That is, an uncurled PBT-based artificial eyelash main body (10, 3000) was prepared, and alignment work (S250) was performed to evaluate changes in the sensitivity of the electrostatic body by workers, the change in bodily sensation of alignment time, and work efficiency. Here, in order to focus on and verify the effect of the moisture content in the artificial eyelash main body 10, the cross-sectional shape of the artificial eyelash main body 10 is circular, but the static electricity suppressing effect is The same tendency is exhibited even when the cross-sectional shape of the artificial eyelash body portion 10 is flat.

  A sample having a moisture content (%) of "None" is an artificial eyelash main body portion not mixed with a moisture adjustment component. However, even if the moisture content adjustment component is not contained, samples with moisture content (%) of “None” are less than 0.1% (or less than 0.1%) due to the influence of ambient moisture and humidity. Water content was shown. The artificial eyelash main part 10 whose moisture content was adjusted by containing (blending) samples containing 0.20%, 0.30%, 1.00% and 5.00% of moisture content (%). It is. Perform the alignment process (S250) with two workers at the same time on the same day at the same place in the same place, in order to reduce the variation due to room temperature / humidity and the skill of the workers, electrostatic sensitivity during the process, alignment time ( The average change in the working efficiency was confirmed by experiment. As for static electricity, the sensitivity of the human hand is more meaningful than the measurement (numerical value) by the electronic device (that is, it makes sense as the evaluation of the alignment process, while the delicate one is understood) So, I adopted that.

  As shown in the table in FIG. 38, first, in the sample with the moisture content “absent”, the electrostatic body sensitivity was “strong”, and the alignment time (average) was 6 minutes and 30 seconds. This is a normal alignment process. As for the sense of work efficiency, it took about 2 minutes to get rid of the static electricity in the alignment.

  In the sample having a water content of 0.20%, the electrostatic body sensitivity was "strong", and the alignment time (average) was 5 minutes and 20 seconds. The alignment time was reduced by about 1 minute (a time reduction of about 20% could be achieved) as compared with the "none" sample. As a change in electrostatic body sensitivity, although there was no sensation of reduction in static electricity, the time to rework alignment was shortened.

  In the sample having a water content of 0.30%, the electrostatic body sensitivity was "weak", and the alignment time (average) was 2 minutes and 45 seconds. The alignment time was reduced by about 4 minutes (a time reduction of about 60% could be achieved) as compared with the “no” sample. As the electrostatic sensitivity changes, it is clearly easier to align, and the reworking time is significantly reduced.

  In the sample having a moisture content of 1.00%, the electrostatic body sensitivity was "weak" and the alignment time (average) was 2 minutes and 10 seconds. The alignment time was reduced by about 4 minutes and 20 seconds than the “no” sample (a time reduction of about 60% or more could be achieved). It is very easy to align, and the need for partial rework has been nearly eliminated.

  In the sample having a moisture content of 5.00%, the sensitivity of the electrostatic body was "none" and no static electricity was felt. Alignment time (average) was 3 minutes 00 seconds. The alignment time was shortened by about 3 minutes and 30 seconds than the "none" sample (a time reduction of about 50% was achieved). It was easy to align, but some rework was needed.

  As can be seen from this example, the alignment process of the artificial eyelash main body 10 in which the water content was adjusted by blending the water content adjusting component was significantly improved. In this example, in particular, the alignment time is improved in the range of 0.20% to 5.00% of the moisture content, and the reworking time is almost equal in the range of the moisture content of 0.30% to 1.00%. It was zero or could be shortened significantly.

  It should be noted that if the water content is increased, the influence of static electricity will be reduced, but on the other hand, the inventor of the present invention can see that the higher the water content, the shorter the period in which the curl (10c) is maintained. It was issued. In addition, since the adhesive (20) whose curing starts with moisture in the air is used, if the eyelash extension 101 (artificial eyelash main portion 10) with too high moisture content (moisture content) is used, curing of the adhesive Operation becomes difficult because the speed is higher than necessary. Furthermore, if the water content is too high, it may expand more easily than when the water content is low, which may lead to the destruction of the adhesive (20), thus reducing the wearing persistence of the eyelash extension. Increase the possibility. There is a relation that the longer the moisture content of the eyelash extension (artificial eyelash main body) is, the shorter the maintenance period of the curl (10c), so by setting the upper limit to the moisture content value (ie, less than a predetermined value) By setting the moisture content, it is possible to control the duration of curling (curvature) and to suppress the case where the curling shape is broken (loosely). In addition, when the flat-shaped artificial eyelash body portion 10 in the embodiment described above is used, even when such a curled shape is broken, it is possible to control with higher accuracy. In the configuration of the present embodiment, the water content (mass%) in the artificial eyelash body 10 is preferably 10% or less, for example 5% or less (in some cases, 3% or less, or 2% or less or 1%) The following is.

  In the method of manufacturing the eyelash extension 101 according to the present embodiment, after the moisture content of the resin 12 is adjusted (S210), the resin 12 is extruded from the mold (S220), and the extruded fibrous material is cut (S230) . As a result, when the artificial eyelash main body 10 is aligned after forming the artificial eyelash main body 10 having the tip 11 (S250), static electricity generated in the artificial eyelash main body 10 can be suppressed, and as a result The alignment step (S250) of the artificial eyelash body 10 can be easily performed. Although the alignment process of the artificial eyelashes main body 10 is a very time-consuming process, according to the manufacturing method of the present embodiment, the static electricity can be suppressed, so that the alignment process (S250) can be easily and cleanly performed. it can. Further, in the step of adjusting the moisture content of the resin 12, the moisture content adjusting component 30 (electrostatic suppressing component) is contained in the resin 12 so that water is directly introduced into the resin 12 to adjust the moisture content. Thus, control of the water content in the resin 12 can be easily performed.

  Furthermore, in the method of the present embodiment, the block (170) of the artificial eyelash main body 10 aligned in the alignment step (S250) is curled (in a batch) (S260), and the state is aligned with high accuracy. The eyelash extension 101 can be made into one block (one row of eyelash extensions) and then fixed (adhered) to the backing sheet 150 (S270). In addition, after fixing the eyelash extension 101 on the backing sheet 150 (for example, after delivery to the salon), it may be stored in a loose state, and may be used for the treatment from that state.

  In addition, the eyelash extension 100 according to the present embodiment contains a moisture content adjustment component (static suppression component) 30. This makes it easy to adjust the moisture content of the artificial eyelash body 10 according to the present embodiment (because it is possible to control the upper limit of the moisture content), so that control / control of the duration of curling of the eyelash extension 101 can be performed. As a result, it is possible to reduce the possibility that the curl (10c) of the eyelash extension 100 becomes defective by giving priority to the effect of suppressing static electricity (work efficiency of the alignment process), so that consumers (wearing Maintain the satisfaction of

  In addition, as a further modification of the present embodiment, the artificial eyelash body portion 10 can be made to contain an antibacterial component (antibacterial agent). The antimicrobial component (antimicrobial material) in the modified example of this embodiment is a metal particle (for example, metal fine particles (nanoparticles) of 1 micrometer or less) or an antimicrobial agent containing a metal (also including an antimicrobial agent of metal ion alone) It consists of For example, one example of the antibacterial component of the present embodiment is silver ion (Ag +), and specifically, silver nanoparticles, particles of silver colloid solution (silver colloid particles), and the like. Here, the silver ion (Ag +) having the antibacterial property can be used, for example, in the form of silver ion water, silver nanoparticles (silver nano solution containing silver nanoparticles), silver colloid particles, and the like. Silver ion (Ag +) is a silver ion which exists as a cation in which an electron is removed from silver (Ag) as an atom, and the size is approximately the same as that of a silver atom, and is a so-called atomic of about 200 picometers. It is a size. Silver nanoparticles are particles in which silver is on the order of nanometers. In addition, it is also possible to use silver nanoparticles in which the finely divided silver ions are held by alumina-silica, which is a mineral. Silver colloidal particles are colloidal silver particles, for example, those which are suspended in a semipermanently suspended state (colloidal state) in a deionized electrolyte. The diameter of the silver colloid particles may be, for example, 0.0001 μm, which corresponds to a size of 800,000 times smaller than the thickness of the hair (80 μm).

  Silver ions can be strongly adsorbed to various bacterial cells, and can block and kill bacterial cell enzymes. Thus, silver ions can control bacterial reproduction. In addition, silver ion has a feature that the antimicrobial effect is relatively strong, and it is also extremely safe for the human body. Therefore, the antimicrobial eyelash extension 100 (101) of this embodiment is wrong. Even if it enters the human mouth, there is an advantage that the problem caused by silver ions does not occur substantially.

  Moreover, the antibacterial component of this embodiment can use things other than a silver ion (Ag +). For example, gold colloid particles contained in a gold colloid solution or platinum colloid particles contained in a platinum colloid solution. Gold colloid particles are particles in a colloidal state in which fine particles (nanoparticles) of 1 micrometer or less are dispersed in a fluid. Platinum colloidal particles (platinum nanocolloid particles) are particles in a colloidal state formed by fine particles of platinum. In addition, in this embodiment, a nanoparticle may refer to a particle of nano order (for example, 1 to 1000 nm or 1 to 100 nm) in particle diameter, and may include particles of 1 nm or less. These nanoparticles may exhibit properties different from solid (bulk) materials of general size due to their extremely large specific surface area etc. One of their properties is that they exhibit antibacterial properties It can be used as an agent. Furthermore, although the antibacterial agent by a metal ion was demonstrated, it is also possible to mix | blend other antibacterial materials with the artificial eyelash main-body part 10 on the conditions which show an antibacterial effect. For example, titanium oxide can be blended into the artificial eyelash body 10 instead of (or together with metal ions (silver ions)) such as silver ions. In addition, it is also possible to use other antibacterial materials of silver ion and titanium oxide. Examples of the antimicrobial material include inorganic antimicrobial agents (those utilizing the bacteriostatic action of metal ions) and organic antimicrobial agents (antimicrobial agents utilizing organic substances, synthetic antimicrobial agents or natural antimicrobial agents).

  The effect of the antibacterial agent (for example, silver ion) in the modified example of this embodiment is not only the antibacterial effect when the eyelash extension 100 (101) is attached to the user, but also when the eyelash extension 100 (101) is stored. There is also an antimicrobial effect in that the inventory of the product is hygienic because it suppresses bacterial growth.

  In addition, although the above-described eyelash extension 100 (101) shows that the surface 10a (10b) of the artificial eyelash main body 10 is not formed with the uneven portion and the rough portion, the present invention is not limited thereto. It is also possible to modify the surface 10a (10b) of the eyelash extension 100 into a roughened one by forming the uneven portion and the rough portion on 10a (10b). By roughening the surface 10a (10b) of the eyelash extension 100, there is an advantage that the adhesive strength of the adhesive (glue) can be improved. As an example of such an eyelash extension, specifically, as shown in FIGS. 39 to 41, an eyelash extension 102 having a roughened surface portion (roughened surface portion) 40 can be used.

  FIG. 39 is a perspective view showing the configuration of the eyelash extension 102 of this embodiment. FIG. 40 shows a cross-sectional view along the line AA in FIG. FIG. 41 shows an enlarged cross-sectional view of a portion B in FIG.

  In the eyelash extension 102 of this embodiment, a rough surface portion 40 is formed on at least the wide surface 10 a side of the artificial eyelash body portion 10. In the example illustrated, it is formed not only on the wide surface 10 a side but also on the narrow surface 10 b side. Although it is preferable to form both (10a, 10b) in that the adhesion is more improved, it is the wide surface 10a that is mainly adhered to the eyelashes, so the surface portion that is exclusively roughened on the wide surface 10a side 40 (roughened surface portion) may be formed.

  Further, the roughened surface portion 40 (roughened surface portion) is formed with the roughened surface portion 40 on the end face 15 a side of the root portion 15 than the midpoint in the longitudinal direction of the artificial eyelash main body portion 10. In particular, the rough surface portion 40 may be formed in a region in contact with the eyelashes, and may be selectively formed only at the portion to which the adhesive 20 is applied.

  The rough surface portion 40 of the present embodiment includes a plurality of granular irregularities 41. In the illustrated example, the roughened surface portion 40 composed of the granular unevenness 41 is formed over the entire circumference of the root portion (end portion) 15. Therefore, the rough surface portion 40 is formed in all directions of the surface of the root portion 15, and the adhesive 20 is applied onto the rough surface portion 40 regardless of the direction in which the adhesive 20 is applied. be able to.

  In the configuration of the present embodiment, the roughened surface portion 40 of the artificial eyelash body portion 10 is formed by applying frost processing. In other words, the artificial eyelash main body 10 is formed with the unevenness 41 generated by the frost processing. Frosting refers to processing that makes the surface rough like frost (or processing that makes the surface rough like frosted glass), and in the present embodiment, asperities 41 are formed on the artificial eyelash body 10 by sandblasting. Sandblasting is a processing method in which an abrasive such as sand is sprayed on the surface. For example, a rough surface portion 40 can be formed on the root portion 15 by mixing an abrasive into compressed air from the compressor and spraying the root portion 15 of the artificial eyelash body portion 10. The sand (abrasive) used for sandblasting is not limited to so-called sand, and an abrasive suitable for forming the unevenness 41 on the artificial eyelash main body 10 can be used.

  The depth (difference in height from the convex portion to the concave portion) of the unevenness 41 of the present embodiment is, for example, about 0.01 mm to 0.1 mm, but is not limited thereto. Specifically, it is determined by the conditions of the frosting (for example, sand blasting) used to form the rough surface portion 40, and it is possible to appropriately form suitable irregularities 41 in accordance with the frosting used. It is.

  In addition, it is possible to form a through hole in the artificial eyelash body 10 and to form a rough surface 40 by the through hole. When the through holes are formed, there is also an advantage that the weight (mass) of the eyelash extension 102 can be further reduced. Even though the weight of each eyelash extension 102 is light, since they can be attached to the user's eyelashes, being able to lighten the weight of the extension affects the fit of the user (wearer) As a result, a comfortable extension can be realized.

  The rough surface portion 40 of the present embodiment can be formed by rubbing a sandpaper (specifically, a sandpaper). The paper file is a tool in which an abrasive is applied to a paper-like sheet used for polishing. In the case of forming the rough surface portion 40 by paper sanding, it is possible to adjust the shape, depth and the like of the unevenness 41 of the rough surface portion 40 by the roughness (count) of the paper sanding used.

  When forming the rough surface portion 40 on the root portion 15 of the artificial eyelash body portion 10, a large number of artificial eyelash main portions 10 are aligned, and then sandblasting is applied to the root portion 15 to roughen in one treatment. A large number of artificial eyelash body parts 10 having surface parts 40 can be formed. Moreover, it is also possible to form many artificial eyelash main-body parts 10 which have rough surface part 40 by processing at once by giving a paper file to root part 15 in the state where many artificial eyelash main-body parts 10 were arranged. It is. Of course, it may be possible to form a rough surface portion 40 by applying a sandpaper to one artificial eyelash main body portion 10. In addition, in the case of the eyelash extension 102 of this embodiment, the roughened surface portion 40 (concave and convex portion 41) may be formed by laser irradiation.

  In the eyelash extension of this embodiment, since the root portion 15 of the artificial eyelash body portion 10 has the rough surface portion 40, the rough surface portion 40 facilitates holding the adhesive 20, The adhesion between the user's eyelash 50 and the artificial eyelash body 10 can be improved. That is, in addition to the effect of the extension 100 (101) described above, the adhesiveness can be further improved. More specifically, in the case of the eyelash extension 102 of the present embodiment, the roughened surface portion 40 increases the surface area compared with the surface in the smooth case (or the unevenness 41) and the adhesive 20 is well retained. Therefore, the adhesive 20 is attached.

  In addition, the artificial eyelash main body 10 is modified to have unevenness, roughness, etc. (roughness, roughness) using a method such as heating, pressing, laser irradiation, etc. (or combining them). It can be done by forming one on the surface of the artificial eyelash body 10. The lines (segments) for unevenness and roughness may be formed along the longitudinal direction of the artificial eyelash body 10, or the direction on the non-longitudinal side of the artificial eyelash body 10 (for example, circumferential direction, It may be formed in the oblique direction).

  Although the present invention has been described above by the preferred embodiments, such descriptions are not restrictive and, of course, various modifications are possible. For example, in the example shown in FIG. 23, the eyelash extension 100 is attached to the upper eyelash 50, but the eyelash extension 100 may be attached to the lower eyelash. Moreover, it is also possible to apply the form of the modification mentioned above to each other (as long as there is no contradiction). Furthermore, in the above-described example, one eyelash extension 100 (101, 102) is attached to one eyelash 50, but a plurality of (two, three, four, etc.) artificial eyelash main body parts 10 The eyelashes 50 may be mounted with a single eyelash extension 100 (for example, a branched eyelash extension or a bifurcated eyelash extension). Also, although the eyelash extensions 100A and 100B are curved, for example, in some cases, it may be possible to make the eyelash extension 100B straight (or slightly curved). In addition, in the attachment method of the eyelash extension 100 mentioned above, fixation with an adhesive agent was mainly used, However, the adhesion method * fixation method (For example, it contracts with a cord, shrinkage by a band (ring), etc.) other than that may be sufficient. Of course, in the current technology, curing and fixing with the adhesive 20 is preferable.

  In the configuration of the above-described embodiment, the example in which the plurality of eyelashes extensions 100 are aligned on the backing sheet 150 has been described, but the eyelashes extensions 100 of this embodiment may be stored in a bag in a loose state. It may be housed in the case 2000 as shown in FIG. Specifically, after manufacturing the static electricity prevention (water content adjustment) eyelash extension 100 according to the present embodiment, it may be removed from the tape 3400 shown in FIG. It may be put in a bag or case 2000 after being attached once.

  In addition, although the technology or characteristics of the present embodiment is that the artificial eyelash main body 10 is more preferable to a flat shape, a circular (approximately circular) one is preferable, and a sufficient technology exists. And the active use of such features are also of high technical value. For example, a technology capable of forming any curl by blending a low temperature denatured resin material with the resin 12 constituting the eyelash extension 100 (artificial eyelash main body 10) is suitably applied to a circular artificial eyelash main body It is added that it is possible. In addition to the flat artificial eyelash main body 10, the upper and lower surfaces may be flat, the entire cross section may be curved, and the cross section may be rectangular (or substantially rectangular). Further, among the above-described techniques, not only the eyelash extension but also a technique applicable to false eyelashes may be possible. In addition, division of the above-mentioned embodiment and a 2nd embodiment is a thing for convenience, and each feature is mutually applicable to that point.

  According to the present invention, it is possible to provide a method of attaching the extension eyelashes, which can improve the wearing comfort of the extension eyelashes and improve the persistence of the extension eyelashes (eyelash extension).
