Description

Socks and their manufacturing method {HOSIERY AND METHOD OF MANUFACTURING THEREOF}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to socks, such as socks and stockings, which are knitted by a sock knitting machine, and in particular, a sock characterized by the configuration of the heel portion, and a manufacturing method thereof.

For example, socks such as socks, stockings (including pantyhose), and sock knitting machine using a circular knitting machine, that is, socks having a forward and backward cylindrical cylinder in which a plurality of knitting needles are arranged to move up and down Knitting by knitting, for example, in the case of a sox consists of an upper opening, a leg, a heel, an instep, a sole and a toe portion (Japanese Utility Model Publication No. 3058783 and Japanese Utility Model Publication No. 3061334). number).

In the piece of socks, the leg part 22, the heel part 23, the instep part 24 and the sole part 25, and the toe part from the side of the opening part 21 used as the inlet of the sock shown in FIG. By knitting in the order of (26), the edge portion of the leg portion 22 and the heel portion 23 is knitted in a tubular shape by one direction rotation (forward rotation) of the cylinder, and the heel portion 23 In the rotation angle range (about half the circumference) of the side which knits the instep part 24 next to the said leg part 22, the knitting needle is held so that a knitting is not performed and the side which knits the heel part 23 is By the knitting needle of about half a circumference, the cylinder is reciprocated in the reverse direction (inverted) in each course, so-called inverted pieces are knitted and knitted to form the necessary bulge as the heel portion 23. At this time, in order to maintain the strength as the heel portion 23 and the like, it is common for the heel portion 23 to switch and knit the knitting yarn to another yarn having strength. Then, when the knitting of the heel portion 23 is completed, it is switched to the original knitting yarn, and is continuous to the instep portion 24 and the heel portion 23 continuous to the leg portion by the forward rotation of the cylinder. The sole 25 is knitted in a tubular shape, and the toe part 26 is knitted, and finally, the knitting is completed by closing the opening of the toe part 26.

As described above, in the conventional knitting of the socks, since the heel portion is formed by the inverted piece by the reciprocating rotation of the cylinder and also requires the switching of the yarn, the improvement of the knitting efficiency cannot be expected, and the switching of the yarn material can be expected. For this reason, there is a possibility that snuffing, cutting off, etc. may occur on the piece, and the productivity is impaired. In addition, the color difference due to the difference of the thread material occurs in the leg part and the heel part, which is not preferable in appearance, and the seam due to the change of the thread material at the boundary part between the heel part, the leg part and the sole part (27, 28) becomes weak and easy to occur, there is a problem in durability.

The present invention has been made in order to solve the problem caused by the inversion of the heel or the switching of the thread in the piece of the conventional socks, the whole is the same or plural combinations of the same knitting in a plurality of combinations without requiring the inversion By knitting in a tubular shape, the heel portion forming a bulging shape can be formed, and the knitting efficiency can be improved while also reducing the amount of squeezing or stretching of the knitting pieces, and the unity with other parts such as the heel portion and the leg. This good and no noticeable color difference is generated, and the present invention provides a sock excellent in appearance and durability, and a manufacturing method capable of efficiently producing the sock.

Socks of the present invention to solve the above problems is made of the leg portion, the heel portion, the foot portion and the sole portion of the sock in successive knitting in a cylindrical shape, at least the foot in the leg portion, the foot portion and the sole portion The area around the heel is knitted into a large-tissue knitting tissue, and at the same time, the heel is knitted into a tissue that is less shrinking than the knitting tissue of the area around the heel, thereby giving bulging to the heel. Characterized in that made. Usually, the said leg part, a heel part, a foot part, and a sole part are knitted continuously by the same knitting yarn by the same or multiple combination.

According to the sock of the present invention, even though the entire body from the leg to the instep and the sole, particularly the entire heel, is knitted in a continuous shape in the squeezed state, in the squeezed state, The heel portion exhibits a bulging shape in comparison with the region around the heel portion of the knitted fabric having a larger contraction than this, and the heel portion by the conventional inverted piece and the heel portion without inferiority are formed in appearance and strength.

In addition, on the knitting piece of the sock, the heel portion can be easily knitted simply by changing the knitting structure without requiring the switching of the inverted piece or the thread for reciprocating the knitting machine cylinder. Therefore, there is no seam due to the change of the thread at the boundary between the heel portion, the leg portion and the sole portion, and there is no fear of snuffing or pulling-out on the piece, and the risk of loosening in use, and the heel There is no noticeable difference in color due to the difference in material between the part and the other part.

In the above socks, it is preferable that the heel portion is incorporated with a boss yarn separately from the knitting yarn for knitting the leg portion, the heel portion, the instep portion and the sole portion every one or more courses. In this case, the heel part can be reinforced by the said boss yarn, and the strength of a heel part can be raised.

Further, in the above socks, the knitting structure of the area around the heel portion at least in the leg portion, the foot portion and the sole portion may be a knitting structure in which a plurality of convex portions formed by a continuous float stitch of a plurality of courses are formed at every required interval. As a result, at least the area around the heel portion can be greatly contracted, and the inflated shape of the heel portion can be more clearly displayed.

It is preferable that the said sole part has a knitting structure in which many convex parts of the circumferential direction by a continuous float stitch were formed in parallel, and the number of courses of the said continuous float stitch which forms the convex part of the said sole part is 3-25 course. Thereby, the convex part by the said continuous float stitch can be formed comparatively large, shrinkage | contraction in a raised state becomes large, and this convex part gives an acupressure massage effect to a sole, and also shows an anti-slip effect.

The sole part is preferably formed by incorporating a boss yarn separately from the knitting yarn for knitting the leg part, the heel part, the instep part and the sole part every one or more courses, thereby reinforcing the sole part and at the same time the convex part. An appropriate hardness can be given to a part, and the said shiatsu massage effect and an anti-slip effect can be heightened further. Moreover, various functions can be given by selection of the raw material of a boss company. For example, by using an antibacterial deodorant, antibacterial and deodorizing functions can be imparted.

In the above socks, it is preferable that the knitting yarn for knitting the leg, the heel portion, the instep portion and the sole portion is made of an elastic yarn, whereby the elasticity can be imparted to the entire sock, and the adhesion and the pressure at the time of wearing are satisfactorily achieved. I can keep it.

In addition, the present invention is a manufacturing method of the socks, in the knitting of the socks by the socks knitting machine, the heel portion, the instep portion and the sole portion of the socks are knitted continuously in a tubular shape. And at least the periphery of the heel portion of the sole is knitted from the heel into a large tissue that has a large contraction, and at the heel portion, the contraction is organized systematically than that of the periphery of the heel portion. It is characterized by providing bulging to a heel part by knitting in this small knitting structure.

Thereby, the socks can be easily and efficiently knitted with the sock knitting machine, without making the heel part the inverted piece, and without changing the yarn, and giving the bulge to the heel part easily. have.

According to the sock of the present invention and the method for manufacturing the same, the whole is knitted in a tubular shape without requiring an inverted piece in the same knitting yarn and without switching the yarn, thereby easily forming an heel portion forming an expanded shape. In addition, it is possible to increase the efficiency of the cutting of the piece while reducing the amount of snares and cuts on the piece. In addition, since it does not require the switching of the yarn as described above, it is possible to obtain a sock having good unity with other parts such as the heel part and the leg part, and no outstanding color difference, and excellent appearance and durability. The productivity of these types of socks can be improved.

Next, embodiments of the present invention will be described with reference to the examples shown in the drawings. 1 is a schematic side view showing a sock of an embodiment of the present invention, FIG. 2 is a schematic front view as seen from the sole side of the sock as described above, and FIG. 3 is an enlarged organization chart of the area around the heel portion of the sock of the present invention. Doing. 4 is a schematic side view illustrating another embodiment. FIG. 5 is a structure explanatory diagram in the case of incorporating a boss yarn, and FIG. 6 is a structure explanatory diagram of a continuous float stitch.

The sock A of the illustrated embodiment shows the case of a sox, in which the numeral "1" in the figure represents an opening at the upper end, "2" is a leg, "3" is a heel, and "4" is Instep, "5" shows the sole, and "6" shows the toe.

The socks (A) is basically a sock knitting machine using a circular knitting machine in the same manner as in the prior art, the leg portion (2), the heel portion (3), the instep portion (4) and the sole part from the opening (1) side (5) and the toe part 6 are knitted one by one, but especially in the case of this invention, even in the knitting of the said heel part 3, the said leg part 2 is carried out without the so-called inversion piece which reciprocally rotates a knitting cylinder. The whole heel part 3, the instep part 4, and the sole part 5 are knitted continuously in the shape of a tubular shape, for example, by the same knitting yarn by one or a plurality of the same or a plurality of combinations. Usually, an elastic yarn is used for the knitting as described later.

In addition, in order to form the heel portion 3 to have a predetermined bulging shape, in the present invention, at least a region around the heel portion of the leg portion 2, the instep portion 4 and the sole portion 5 For example, as shown in the drawing, the entire area of the leg portion 2, the instep portion 4 and the sole portion 5 is knitted into a large tissue that has a large contraction apart from the contraction caused by the elasticity of the seal material. At the same time, the heel portion 3 is knitted into a plain knitted tissue having a smaller contractile structure than the knitting tissue in the region around the heel portion, usually a flat tissue that is hardly contracted systematically. In the heel portion 3 is given bulging.

The heel part 3 is said to have the width which can cover at least the sole side of a heel at the time of wearing, Preferably the width | variety which can cover from the sole side to near ankle bone, the shape is for example The present invention is not limited to an almost elliptical shape as shown in the drawing, and can be implemented by various shapes corresponding to the shape of the heel. Usually, the said sole part 5 is formed continuously from the said heel part 3 as shown in the figure. The heel portion 3 may be knitted only with the knitting yarn knitting the whole sock. However, in practice, the boss yarn is cutbossed separately from the knitting yarn for one or more courses, preferably for each course. It is preferable that the heel portion 3 be reinforced so that the heel portion 3 can be reinforced. Fig. 5 shows an example of the incorporation of the boss yarn, and the boss yarn Y2 is incorporated into the yarn knitting method using a separate boss yarn Y2 as a cut boss for the knitting yarn Y1 of the base knitting fabric. The end portion Y2a of the Y2 is cut into the required length and remains on the inner side (sock inner side) of the letter.

The knitted tissue having a large contraction may be any knitted tissue as long as the tissue is largely contracted than the heel portion 3 of the knitted tissue having a small contraction in a squeezed state. However, the continuous float as illustrated in FIG. It is preferable that a knitting structure having irregularities in which a plurality of convex portions 7 and 8 formed by stitches, that is, portions 7 and 8 formed by portions 11 of continuous float stitches forming a plurality of welt loops 11a are formed at required intervals. .

For example, as a piece of large-tissue contraction of the leg portion 2 and the instep portion 4, a welt loop having a plurality of courses, preferably 2 to 20 courses, is formed for each required course based on a flat plane. A portion of the continuous float stitch is arranged in the widthwise direction at appropriate intervals. After squeezing, a portion of the continuous float stitch contracts in the unidirectional direction to form a convex portion 7 in the circumferential direction. It is formed into a piece of uneven structure formed. In this case, the convex portion 7 can stimulate the wearer's leg to exert acupressure massage effect, and can also exert an effect such as eliminating edema of the leg. In the organization chart of FIG. 3 "11" shows the portion of the continuous float stitch which forms the convex portion 7 in the leg 2 and the sole 4, and "12" shows the portion of the flat. have.

The convex portion 7 does not necessarily need to form a concave shape that is continuous in a straight line in the circumferential direction, but is a convex portion that forms a continuous wave in the circumferential direction, a convex portion forming a diagonal concave shape, and a circumferential direction. It is possible to implement by various types of convex portions, such as a convex portion interrupted by a concave portion, a convex portion arranged in a ridge shape, or a combination thereof. In addition, the convex part 7 does not necessarily need to be formed uniformly over the whole area | region of the said leg part 2 and the instep part 4, For example, as shown in the example of FIG. What is necessary is just to arrange | position in a circumference | surroundings area | region of the said heel part 3, etc. to arrange | position in a pattern.

The heel portion 3 and the heel in the area of the course range slightly wider than the heel portion 3, as in the example of FIG. It is set as the range 9 containing the said instep part 4 on the opposite side to the part 3, and it is supposed that a bulge can be contracted in the heel part 3 by contraction of the said range 9.

In addition, as the knitting structure with a large shrinkage of the heel portion 5, for example, a continuous float stitch in which a welt loop of 3 to 25 courses is formed for each required course on the basis of the flat, similarly to the leg portion 2 and the like. The convex part forming the convex shape in the circumferential direction slightly higher than the convex part 7 such as the leg part 2 by contracting the part of the continuous float stitch in one direction after squeezing into the tissues arranged at appropriate intervals. (8) is formed into a uneven piece consisting of irregularities. In this case, the slightly higher convex portion 8 stimulates the sole of the wearer, exerts a massage effect of a good feeling such as stepping on bamboo, and has an effect of alleviating fatigue. In the organization chart of FIG. 3, "13" represents the portion of the continuous float stitch forming the convex portion 8 in the sole portion 5, and "14" represents the portion of the flat surface.

The convex portion 8 of the sole portion 5 is not limited to forming a concave shape continuous in a straight line in the circumferential direction, but a convex portion intersecting a wave or a diagonal concave shape in the circumferential direction. Implementation by various convex parts, such as a convex part, the convex part arrange | positioned in the shape of a ridge, or the combination of these convex parts, is possible. In addition, the convex part 8 does not necessarily need to be formed in the whole area | region of the sole part 5, It can also be formed in part, and should just be arrange | positioned in the peripheral area of the said heel part 3 at least.

In the sole portion 5, the base and the knitted fabric piece are the same as in the heel portion 3, in the same manner as in the heel 3, in every one or more courses, preferably in each course. Apart from the yarn, it is preferable to incorporate a boss yarn (not shown) having a function different from the knitting yarn. That is, the sole portion 5 can be reinforced by the boss, and the acupressure massage effect and the anti-slip effect by the convex portion 8 can be enhanced, and various functions can be given by the boss. For example, by using an antibacterial deodorant, it is possible to give antibacterial and deodorizing functions.

The sole portion 5 corresponds to a portion except for the areas of the heel portion 3 and the toe portion 6 at the sole side, and may be almost the same width as the sole side, but in the case of the illustrated embodiment The convex part 8 is formed and / or a boss yarn is incorporated, and the area | region which changes knitting structure with the sole part 4 side is set to be slightly narrower than the width of the sole part, or to the shape of the sole. In correspondence, the side closer to the toe part 6 is set to a slightly wider width.

In addition, although not shown in the figure, the band region along the inner side of the boundary of the heel portion 3 with the other portions such as the leg portion 2 and the instep portion 4 serves as a buffer for tissue change. The float stitch to be performed can be carried out by being dotted.

As the knitting yarn used for said socks (A), elastic yarns, such as a single cover yarn or double cover yarn which covered the nylon filament to a polyurethane elastic yarn, are used preferably. By using an elastic yarn, elasticity can be appropriately applied to the whole sock, and adhesiveness and pressure at the time of wearing can be kept favorable. The thickness of the elastic yarn to be used can be set appropriately in accordance with the aspect of the sock to be manufactured. For example, a thread of 40 to several hundred dtex is used.

As described above, the sock A of the present invention is a forward rotation piece for rotating a knitting cylinder in the same direction in a piece of socks by a sock knitting machine, and the whole is continuously knitted in a tubular shape by the same knitting yarn. At least the area around the heel in the leg 2, the instep 4 and the sole 5 is knitted into a tissue with large shrinkage, for example, having irregularities as described above. In the heel portion 3, the heel portion 3 is knitted into a knitting tissue, for example, a flat tissue, which has a smaller contraction than the knitting tissue in the region around the heel portion.

For this reason, even though the whole including the heel part 3 is knitted continuously by the same knitting yarn, in the squeezed state, the heel part 3 of the knitting tissue with small shrinkage is more In addition, it exhibits a bulging shape compared to the region around the heel portion of the large-tissue large-shrinkage, and the heel portion 3 and the heel portion 3 without inferiority are formed in appearance and strength. In addition, in order to form the heel portion 3 on the knitting piece of the socks A, it is easy to knit simply by changing the knitting structure without requiring the switching of the inverted piece and the thread by the reciprocating rotation of the knitting machine cylinder. As a result, the seam by the change of a thread does not generate | occur | produce on the boundary of the heel part 3, the leg part 2, or the sole part 5, and the occurrence of a snuff or a rope shortening on a piece, and in use There is no fear of loosening, and no noticeable color difference occurs due to the difference in the yarn material between the heel portion 3 and the other portion. Therefore, the socks excellent in appearance and durability can be obtained, and the productivity of this kind of socks can be improved.

The present invention can be preferably used for various socks such as socks, stockings including pantyhose.
