Description

  The present invention relates to a support garment formed of a stretchable material and worn in close contact with a wearer's skin surface. More specifically, the present invention relates to a garment used for compressing or tightening a wearer's muscles, ligaments, tendons, joints or the like and applying tactile stimulation to protect, limit, reinforce, strengthen, or the like.

  Recently, in order to treat or prevent pain in muscles, ligaments, tendons or joints (hereinafter simply referred to as “muscles”) due to disease or fatigue, and to maintain posture or support exercise, the muscles are compressed or tightened. Inner wear with the function to do has been developed.

  These inner wears are designed so that a higher pressure (tightening force) is applied to parts corresponding to muscles or the like than other parts when worn. Then, by compressing or tightening the muscle or the like with this wearing pressure, the load on the muscle or the like is dispersed and the load is reduced to prevent pain, fatigue or injury of the muscle or the like.

  For example, Patent Document 1 is formed of a stretchable material as a whole and has a high pressure region with a strong tightening force and a low pressure region with a weak tightening force, and the high pressure region corresponds to at least the back of the wearer. A shirt for supporting the movement of the upper body of the wearer, characterized in that it includes a first region, is disclosed.

  In Patent Document 2, the upper body wear is manufactured in a seamless integrated shape using a stretchable material, and the upper body wear is used to apply pressure to the necessary part of the body and take a posture with a taping effect. Ware for controlling and correcting body shape is disclosed.

  The innerwear with these compression and tightening functions can be used as it is, so it can be worn more easily than conventional belt-like supporters or taping tapes that are pressed or supported by belts or stays. The appearance after mounting is also good.

  However, in these inner wears, unlike conventional supporters, taping tapes, etc., the wearing position cannot be firmly fixed by belts, stays, tapes, etc. There is a problem that “displacement etc.” is likely to occur. If a shift or the like occurs during wearing, the set wearing pressure cannot be applied to a desired muscle or the like, and a sufficient effect may not be obtained. This is a problem particularly when the inner wear is used for sports with a lot of movement, or when used for a long time for daily use.

  In order to prevent the occurrence of a shift in the wearing position or the like, it is considered to increase the pressure applied to the part corresponding to the muscle or the like or the pressure applied to the entire wear. However, in this case, the feeling of wear deteriorates due to excessive pressure, or considerable force is required for wearing, which makes the wearing inconvenient.

  As a solution to such a problem, for example, Patent Document 3 proposes a stocking in which the surface of an elastic cuff that presses the buttock is covered with a non-slip material such as silicone.

  On the other hand, in connection with the present invention, Patent Document 4 discloses that a sea-island composite fiber unstretched yarn having an extremely large number of islands is fluidly stretched, or the stretched yarn after fluid stretching is further stretched or heat-treated. Nanofibers having a fiber diameter of 10 to 1,000 nm are disclosed. This nanofiber is a fine polyester fiber that has excellent mechanical strength and is effective for applications requiring light weight, heat retention, and moisture absorption.

  Patent Document 5 describes an ink-jet printing method in which an image is printed by ejecting ink-jet ink for textile printing onto a fabric. Patent Document 6 discloses a method of manufacturing a fabric having a fine three-dimensional pattern in which a fiber-exhaust processed region and a surrounding fiber-extracted unprocessed region are clearly divided using inkjet printing. It is disclosed.

JP 2004-263362 A JP 2007-138335 A JP 2000-510743 A JP 2005-325494 A JP 2007-247109 A JP 2006-219809 A

  In order to effectively exert the function of innerwear with compression and tightening functions, prevent the occurrence of displacement of the wearing position due to exercise or prolonged wearing, and set the desired pressure It is necessary to give it properly to muscles.

  The stocking disclosed in Patent Document 3 prevents a wearing position from being shifted by a non-slip material such as silicone. However, this type of anti-slip material may cause stuffiness or itchiness when used for a long time, and there is a problem that it stops wearing on the way because of poor wearing feeling. If it is not worn continuously, the functions of the innerwear will not be exhibited effectively.

  Therefore, the present invention prevents the occurrence of a shift in the wearing position in the clothing such as the innerwear having a function of compressing or tightening the joint or the like, and the wearing feeling does not deteriorate even when worn for a long time. The main purpose of the present invention is to provide clothing that can be quickly recognized by the wearer when there is a shift in the wearing position or a change in posture.

  In order to deal with such problems, the present inventors first focused on the wearer's somatic sensation, particularly tactile sensation and pressure sensation, as an index for comfortably wearing clothes for a long time. Then, subjective data such as a feeling that the wearer receives when a predetermined friction or pressure is applied, for example, a feeling of support, a feeling of pressure, a feeling of comfort, a feeling of fit, a feeling of strangeness, and a feeling of stability were analyzed. As a result of this analysis, the present inventors have found that the perception pattern of the sensation received by the wearer greatly depends on tactile stimulation.

  Furthermore, the present inventors have also paid attention to the skin structure and the tactile receptor in the skin. There are innumerable fibrous crevice on the skin surface. The skin groove has a depth of several tens to several hundreds of μm and a width of several hundreds of μm, and functions to actively receive tactile stimulation by increasing the surface area of the skin. In addition, it is known that the tactile receptor on the skin can recognize irregularities of several μm to several tens of μm, and receptor molecules such as TRPV3 and TRPV4 that are supposed to accept mechanical stimuli are one epidermal cell having a size of several tens of μm. It has been shown to exist in one.

  From these facts, the present inventors appropriately control tactile stimulation in consideration of functions such as skin structure and tactile receptors in order to set the perception pattern of the sensation received by the wearer to a desired pattern. I thought it was necessary. Then, we examined the relationship between tactile stimulation and sensory perception patterns for the fabric characteristics of various clothes. As a result, it has been found that the skin contact surface of the clothing can be made into a predetermined form, and a tactile stimulus can be applied to the tactile reception function of the skin, so that the wearer can effectively perceive a sense of support and the like, thereby completing the present invention. It came to.

That is, the present invention is a garment that is formed of a stretchable material and is worn in close contact with the skin surface of the wearer, and is one or more sites selected from the wearer's muscles, ligaments, tendons, or joints Is provided with an action region that can contact the skin surface of the part to give a tactile stimulus, and a pattern made of a fibrous body having a line width of 10 to 50,000 nm is provided on the skin contact surface of the action region. The present invention provides a garment formed and provided with frictional characteristics different from those of other areas other than the action area. The action area of the clothing exhibits a frictional characteristic different from that of the other area by a pattern made of a fibrous body formed on the skin contact surface, and gives a tactile stimulus different from that of the other area to the wearer. Thereby, in this clothing, it becomes possible for the wearer to easily recognize tactile stimulation from the skin contact surface of the action area.
The line width of the fibrous body is 10 to 50,000 nm, and preferably 10 to 1,000 nm. By forming a pattern with a fibrous body having a line width of 10 to 50,000 nm on the skin contact surface of the active region, the pattern can be brought into close contact with the skin surface and tactile stimulation can be imparted to a wide skin surface area. . Furthermore, by forming a pattern with a fibrous body having a nano-order line width of 10 to 1,000 nm, it becomes possible to further enhance the adhesion to the skin surface and effectively impart tactile stimulation.
In the garment according to the present invention, the pattern can be formed by weaving or knitting fibers as a fibrous body. In addition, this pattern may be formed of a fibrous body formed by applying coating and / or powder by spraying on the skin contact surface of the working area.
These patterns may comprise a plurality of pattern shapes. Furthermore, when the said action | operation area | region provided separately in the area | region corresponding to two or more site | parts selected from a wearer's muscle, a ligament, a tendon, or a joint is formed in the skin contact surface of each action area | region. The patterns may have different pattern shapes.
In the garment according to the present invention, the action area is composed of a fabric made of fibers having a larger line width than the fibrous body, and the pattern formed on the skin contact surface of the fabric by the fibrous body. It is preferable that
This working region preferably has a higher tightening force than other regions and preferably supports one or more sites selected from the wearer's muscles, ligaments, tendons or joints. The landing pressure in this working region can be set to 40 hPa or less.
The clothing according to the present invention covers one or more parts selected from an ankle, knee, calf, thigh, forearm or upper arm.

In the present invention, the “fibrous body” is a long and thin line, that is, a line having a sufficient length compared to the width (thickness), and the line width is 10 to 50,000 nm. Refers to things. Specifically, the fibrous body may be a fiber (fiber), or may be a fibrous structure formed by application by spraying paint and / or powder.
The fiber as the fibrous body includes natural fiber and chemical fiber. Among these, chemical fibers include synthetic fibers (polyester synthetic fibers, polyamide synthetic fibers, polyurethane synthetic fibers, polyacrylonitrile synthetic fibers, polyolefin synthetic fibers) and semi synthetic fibers (cellulose semi synthetic fibers, Protein-based semi-synthetic fibers), regenerated fibers (cellulose-based regenerated fibers), inorganic fibers (glass fibers / carbon fibers) and the like are included.
The fibrous structure formed by application of the paint and / or powder by jetting includes an uneven structure formed on the surface of the fabric by the printed paint (ink) itself, and the surface of the fabric by the printed discharging agent. The concavo-convex structure formed in is included.

  The “line width” of the fibrous body refers to a width in a direction perpendicular to the longitudinal direction of the fibrous body. When the fibrous body is a fiber, the line width means a fiber diameter that is an inscribed circle diameter of the fiber cross section. In addition, when the fibrous body is a fibrous structure formed by applying paint and / or powder by spraying, the line width is the width of the linear concave or convex portion that forms the fibrous structure. Means.

  Furthermore, the “pattern” is defined as a pattern formed by setting the thickness, material, density, form, fabric structure (knitted fabric, woven fabric, non-woven fabric, etc.) of the fibrous body to certain conditions. The This pattern may be formed by arranging the fibrous bodies regularly so that a predetermined form appears repeatedly, or the arrangement of the fibrous bodies is not regular, but is designed and decorated. It may be formed so as to exhibit a predetermined form.

  According to the present invention, in a clothing having a function of compressing or tightening a joint or the like, the occurrence of a shift in the wearing position is prevented, and a comfortable wearing feeling is exhibited even when worn for a long time. When a change in posture or the like occurs, clothing is provided that allows the wearer to quickly recognize this.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments for carrying out the invention will be described with reference to the drawings. In addition, embodiment described below shows an example of typical embodiment of this invention, and, thereby, the range of this invention is not interpreted narrowly.

1. Calf Clothing (1) Overall Shape of Clothing FIG. 1 is a schematic view showing clothing used for calf support according to a first embodiment of the present invention. (A) is a front view and (B) is a rear view.

  In the figure, the clothing denoted by reference numeral 1A is formed of a stretchable material, and is formed into a cylindrical shape that can cover the wearer's calf. The clothing 1A is worn while being in close contact with the skin surface of the wearer's lower leg (front shin and calf) due to the stretchability of the material.

  The material of the clothing 1A is, for example, a polyamide synthetic fiber, a polyester synthetic fiber, a polyurethane synthetic fiber, a polyacrylonitrile synthetic fiber, a polyolefin synthetic fiber, a filament yarn made of a cellulose fiber, a spun yarn, a blended yarn, Twisted yarn, processed yarn and the like can be used. These materials are formed into the overall shape of the clothing 1A by a conventionally known method.

(2) Action area | region Clothing 1A is equipped with the action area | region 10 which contacts the skin surface of this site | part in the area | region corresponding to parts, such as a wearer's muscle. The action region 10 functions to support the wearer's muscles and the like and to apply tactile stimulation to the skin surface such as the muscles.

  Specifically, the action area 10 of the clothing 1A according to the present embodiment has a function of supporting the wearer's gastrocnemius muscle and providing tactile stimulation by contacting the skin surface of the calf.

  For this reason, the action area 10 of the clothing 1A is formed in a substantially Y shape, and a base part covering the skin surface of the Achilles tendon and a branch part extending from the base part in two directions along the outer edge of the gastrocnemius muscle The shape which consists of.

  The action area 10 can be provided, for example, by separately creating the cloth of the action area 10 and the cloth of another area, and combining them by sewing, welding, or the like. Further, for example, after the entire shape of the clothing 1A is formed, the action region 10 may be formed by inserting / removing a predetermined thread, sewing a predetermined fabric, or the like.

  A preferred embodiment of the action region 10 is an embodiment in which a pattern made of a fibrous body having a line width of 10 to 50,000 nm is formed on the skin contact surface of the base fabric using a fabric such as a woven fabric, a knitted fabric or a non-woven fabric as a base fabric. (The pattern formation will be described in detail later). In this aspect, it is preferable that the fabric used as the base fabric is composed of fibers having a large line width as compared with the fibrous body forming the skin contact surface pattern. Specifically, the fabric serving as the base fabric is preferably a fabric composed of fibers having a fiber diameter larger than 1,000 nm or yarns having a diameter larger than 50,000 nm. These fibers or yarns include polyamide-based synthetic fibers, polyester-based synthetic fibers, polyurethane-based synthetic fibers, polyacrylonitrile-based synthetic fibers, polyolefin-based synthetic fibers, cellulose-based fibers, etc., or filament yarns made from these fibers, spun yarns Blended yarn, twisted yarn and processed yarn can be used.

  As described above, the function region 10 is formed from a fabric composed of fibers having a large line width as a base fabric, and a pattern is formed on the skin contact surface by a fibrous body having a small line width, thereby supporting the function region 10. In addition, the tactile stimulation function can be stabilized and the degree of compression and stimulation can be easily controlled.

(3) Support function The action area 10 can exert higher tightening force (compression force) than other areas by giving it higher elasticity and elasticity than other areas of the clothing 1A. it can. Based on this tightening force, the action region 10 compresses or tightens the wearer's muscle or the like to protect, limit, reinforce, strengthen, or the like their functions. It should be noted that the tightening force (compression force) of the other region other than the action region 10 may be set higher than that of the action region 10 depending on the wearing part of the clothes and the purpose of use.

  Specifically, the action region 10 of the clothing 1A according to the present embodiment presses or tightens the gastrocnemius muscle and the Achilles tendon of the wearer to suppress the shake of the gastrocnemius muscle and support the Achilles tendon.

  In order to obtain a comfortable wearing feeling, the pressure applied in the action region 10 is preferably 40 hPa or less, more preferably 27 hPa or less, and particularly preferably 20 hPa or less.

  In the clothes according to the present invention, a pattern made of a fibrous body is formed on the skin contact surface of the action area 10, and the frictional characteristics different from other areas other than the action area are imparted, so that it is difficult for the wearing position to shift. In addition, even when a deviation or the like occurs, the wearer can quickly recognize this (details will be described later). Accordingly, in the clothing 1A, since it is not necessary to perform excessive compression or tightening in the action region 10, the pressure applied in the action region 10 can be set within the above numerical range. Thus, the clothing 1A can be smoothly worn without requiring a large force when worn, and a comfortable wearing feeling can be obtained without giving discomfort due to compression or tightening even when worn for a long time.

  Further, in the clothing according to the present invention, the portion that becomes the skin contact surface to which frictional properties are imparted is formed in a pattern made of a fibrous body having a very thin line width. Can be formed with a thin and lightweight fabric. As a result, the clothing 1A can reduce discomfort due to compression and tightening due to the bulk and weight of the fabric even when worn for a long time, and also provides stability, support, comfortable wearing, etc. to muscles etc. It becomes possible to make it easy to recognize. Furthermore, due to the high adhesion and adaptability of the action region 10 to the skin, it is possible to enhance the effect of protecting, limiting, reinforcing, strengthening and the like functions of muscles and the like even with a thin and lightweight fabric.

In order to obtain such a muscle reinforcement effect and a comfortable wearing feeling, the fabric constituting the action region 10 is preferably a fabric having a thickness of less than 0.6 mm and a weight per unit area of less than 250 g / m ^2. A fabric having a thickness of less than 0.3 mm and less than 150 g / m ² is more preferable.

  In addition, the measurement of a wearing pressure can be performed by measuring the compression pressure in the action | operation area | region at the time of wearing of clothes using an air-type pressure measuring device (made by AMI), for example. Specifically, a pressure sensor of a measuring instrument is installed between the action region of the clothes and the corresponding skin surface in the state where the clothes are worn, and the compression pressure measured at that time is calculated as the wearing pressure.

(4) Tactile stimulation function A pattern made of a fibrous body having a line width of 10 to 50,000 nm is formed on the skin contact surface of the action region 10, and friction characteristics different from those of other regions are imparted. That is, a predetermined pattern is formed on the skin contact surface of the action region 10 by setting the thickness, material, density, form, fabric structure (knitted fabric, woven fabric, non-woven fabric, etc.) of the fibrous body to certain conditions. This pattern exhibits frictional characteristics different from those of other regions. As a result, the skin contact surface of the working area 10 can give the wearer a tactile stimulus that is different from the other areas.

  Furthermore, the pattern of the skin contact surface of the action region 10 is formed by a fibrous body having a line width equal to or smaller than the depth and width of the skin groove, so that it can be easily adhered to the skin groove. That is, the pattern formed by the fibrous body by setting the line width of the fibrous body to 10 to 50,000 nm with respect to the depth of several tens to several hundred μm and the width of several hundred μm of the skin groove. It adheres to the skin groove and is adapted to the skin extension. Thereby, the skin contact surface of the working area 10 can effectively provide tactile stimulation to a large skin surface area. In addition, the skin contact surface of the working area 10 has a soft tactile sensation and excellent ventilation / sweat wicking function, and it is comfortable without causing stuffiness or itchiness due to the pattern formed with very thin fibrous bodies. Demonstrate a comfortable wearing feeling.

  In order to effectively exert the support function of muscles and the like by the action area 10, the wearing pressure of the action area 10 is appropriately prevented by preventing a shift in the wearing position of the clothes caused by exercise or wearing for a long time. It needs to be added to muscles.

  In clothing 1A, the skin contact surface of the action area 10 is configured to effectively apply a tactile stimulus that is different from other areas, so that the wearer can easily touch the tactile stimulus from the skin contact surface of the action area 10. To be recognized. Therefore, when a shift occurs in the wearing position of the action region 10, the wearer can easily recognize the shift and correct it.

  In addition, in the clothing 1A, the friction characteristics of the skin contact surface of the action area 10 are designed so that the surface friction is larger than that of other areas, thereby effectively preventing the displacement of the action area 10. Can do.

  Furthermore, in the clothing 1A, the tactile stimulation is effectively applied by the skin contact surface of the action area 10, so that the wearer feels supportive feeling by physiological reflex by the tactile stimulation without excessive tightening or compression. It is possible to effectively recognize and support the transition to an appropriate posture and the maintenance of an appropriate posture.

(5) Pattern The pattern formed on the skin contact surface of the action region 10 is not particularly limited as long as it is a pattern formed by a fibrous body having a line width of 10 to 50,000 nm. One or more fibrous bodies The outer shape can be configured. The pattern is preferably a pattern in which the fibrous bodies are regularly arranged so that a predetermined form appears repeatedly. However, the arrangement of the fibrous bodies is not regular, but the pattern is designed and decorated to have a predetermined shape. It may be formed to take the form of

  Only one type of pattern may be formed in one working region 10, or a plurality of different patterns may be formed. Further, as in the case of the clothes 1C described later, when the separate action areas 10 are provided in areas corresponding to two or more parts selected from the wearer's muscles, ligaments, tendons or joints, each action area 10 Different patterns can be formed on the skin contact surface. In this manner, by forming a plurality of different patterns in the action region 10, it is possible to apply an optimal tactile stimulus according to the site and purpose.

(5-1) Pattern formation by fiber The pattern of the skin contact surface of the action area 10 is a fibrous body having a line width of 10 to 50,000 nm. As the fibrous material satisfying the line width, natural fibers or chemical fibers which are conventionally known fibers can be employed. In particular, synthetic fibers such as polyester synthetic fibers, polyamide synthetic fibers, polyurethane synthetic fibers, polyacrylonitrile synthetic fibers, polyolefin synthetic fibers, semi synthetic fibers such as cellulose semi synthetic fibers and protein semi synthetic fibers, Regenerated fibers such as cellulose-based regenerated fibers, and chemical fibers such as inorganic fibers such as glass fibers and carbon fibers can be suitably used. The form of the fiber used is preferably a filament that is a single continuous long fiber, and more preferably a filament yarn composed of one or more filaments. As the filament yarn, a monofilament yarn composed of a single filament, a multifilament yarn composed of a plurality of filaments, an alignment yarn in which a plurality of filaments are aligned, a twisted strand, a filament processed yarn that has been stretched or bulked, A form such as a covered yarn obtained by winding a filament yarn around a filament yarn in a coil shape can be used, and a fiber-like pattern can be formed by using one or a plurality of these yarns.

  Among these, as the fibrous body, it is particularly preferable to employ a so-called nanofiber having a line width (fiber diameter) of 10 to 1000 nm. For example, the fine polyester fiber described in Patent Document 4 can be used.

  By forming a pattern made of nano-order ultrafine fibers on the skin contact surface of the action area 10, the ultrafine fibers can be brought into close contact with the wearer's skin surface, and tactile stimulation can be effectively applied and recognized. Moreover, a comfortable wearing feeling such as a slimy texture and touch can be realized.

  In addition, by forming a pattern with nanofibers having a surface area many times that of commonly used fibers, the surface friction of the skin contact surface of the working area 10 can be increased, and displacement during wearing is suppressed. Further, tactile stimulation, compression, tightening, etc. can be applied continuously, discontinuously or intermittently to the target site.

  Formation of the pattern by the fiber can be performed by weaving, knitting, entanglement, alignment, bonding, or the like of the fiber (including the yarn made of the fiber), but it is preferably formed by weaving or knitting. As the yarn made of fiber, monofilament yarn, multifilament yarn, alignment yarn, twisted yarn, stretchable yarn, bulky yarn, covered yarn and the like can be used. The pattern formation with fibers may be formed using only one type of these fibers or yarns made of fibers, or may be formed using a plurality of types.

Further, as another example of pattern formation by weaving, a yarn 22 made of a plurality of fibers 21 obtained by plain weaving, twill weaving, satin weaving, or the like can be used. Fig. 2 (B-1) shows a plain weave pattern of yarn 22, (B-2) shows a twill weave pattern, and (B-3) a satin weave pattern. The yarn 22 is a multifilament yarn composed of a plurality of fibers 21, and can be used in the form of, for example, an alignment yarn, a twisted yarn, a stretchable yarn, a bulky yarn, or the like.

  Further, a pattern may be formed by a knitting structure by knitting using the same material as the fiber 21 and the yarn 22 shown in FIG. As pattern formation by knitting, pattern formation by warp knitting structure or weft knitting structure using fiber 21 or yarn 22 can be used. As a pattern by the warp knitting structure, a fabric pattern by tricot knitting, cord knitting, atlas knitting, chain knitting, etc. can be used. As a pattern by the weft knitting structure, a fabric pattern by flat knitting, rubber knitting, pearl knitting, etc. can be used. . In addition, these knitting structures may be appropriately combined with a double structure using two sheets, a tuck knitting, a transfer knitting, a floating knitting, a pile knitting, a splicing knitting, etc. to change the pattern of the skin contact surface. Good.

  When the skin contact surface of the action area 10 is formed of a knitted structure, by adjusting the material, thickness, number of inserted fibers (density), etc. of the fiber 21 or yarn 22, the knitted structure can be changed to easily adjust the friction characteristics. it can. In addition, by changing the yarn material, thickness, and the number of inserted yarns (density) as appropriate in a series of knitting steps, the action region 10 having a plurality of different friction characteristics by knitting knitting is formed on a single continuous fabric. It is possible to form, and a gradation of friction characteristics can be easily formed.

Furthermore, it is also preferable to form an opening by a knitted tissue on the skin contact surface of the action region 10. This hole is a recess formed on the skin contact surface by a double knitting structure such as a double raschel knitting or double tricot knitting (see the opening 30a in FIGS. 3A to 3C), mesh fabric or lace. A structure such as a through-hole (see FIGS. 3D to 3F) 30b formed in a fabric constituting the skin contact surface by a knitted tissue such as a fabric can be used. By adjusting the shape, size, area ratio, etc. of the openings formed on the skin contact surface of the action area 10 within a predetermined range, the contact area, contact area, contact pressure, etc. between the action area 10 and the skin can be easily adjusted. Thus, the tactile stimulus to be applied can be adjusted. The shape of the opening to be formed is not particularly limited, and examples thereof include a substantially circular shape, a substantially elliptical shape, a substantially triangular shape, a substantially rectangular shape, a substantially pentagonal shape, a substantially hexagonal shape, and a substantially octagonal shape. It is preferable to arrange.

(5-2) Pattern formation using application by spraying paint and / or powder The pattern of the skin contact surface in the action area 10 is formed on the skin contact surface using application by spraying paint and / or powder. It can also be constituted by a fibrous body.

  In this case, the fibrous body can have a fibrous structure formed by application by spraying paint and / or powder, and the working area 10 has friction characteristics that make it easier to perceive a tactile sense than other areas other than the working area. It can also be. Each of these fibrous structures has a shape that is extremely long with respect to the width (thickness), and the line width is 10 to 50,000 nm, and the line width is preferably 10 to 1000 nm. . If application by spraying is used, the working region 10 (fibrous pattern) having a predetermined shape and position can be formed easily and accurately. Specifically, (1) resin characteristics or powder characteristics of the coating material or powder itself to be applied, (2) uneven structure of the applied coating material or powder formed on the fabric surface in the working region, (3) coating The frictional characteristics of the working region can be easily adjusted by the uneven structure formed on the surface of the fabric by the extracted discharging agent.

  As a method of forming a pattern made of a fibrous body on the skin contact surface of the action region 10 using application by jetting, for example, (1) a paint is applied to the skin contact surface of the fabric of the action region 10 by jetting from a nozzle. Or a method of directly applying powder and forming a fibrous pattern according to the shape and position of the coated surface, (2) printing a pattern made of a fibrous body of a predetermined shape on another transfer sheet, etc. by nozzle ejection Alternatively, a method of transferring the transfer sheet to a predetermined position in the action area 10 can be employed. The coating material or powder to be applied is not particularly limited as long as it can be easily ejected from the nozzle and can make the action region 10 have a frictional characteristic that makes it easier to recognize the sense of touch than other regions other than the action region. For example, dyes, resins, powders, or a mixture thereof can be used. Moreover, you may use the aspect which coats paint coating and powder coating repeatedly. As the spray coating method, it is particularly preferable to use an ink jet printing method.

  Ink-jet printing processes the original pattern of the pattern to be formed with a computer and prints the result using an ink-jet method, so that various patterns can be created easily and at low cost.

  Therefore, if a fibrous body (fibrous structure) and a pattern made of this fibrous body are formed on the skin contact surface of the working area 10 by ink jet printing, a desired surface can be obtained depending on the part of the skin surface with which the working area 10 comes into contact. A pattern can be formed.

  Pattern formation by inkjet printing can be performed by a conventionally known method. For example, when forming a fibrous body by the inkjet ink itself for textile printing ejected by the inkjet method, (a) a step of pre-treating the skin contact surface of the action area 10 with a bleeding inhibitor, glue, etc. b) A step of directly or indirectly attaching the ink by an ink jet method, (c) a post-treatment step by heating color development, washing, drying, or the like. In each of these steps, a known pretreatment agent or ink disclosed in Patent Document 5, an ink jet ejection method, an ink fixing process, a cleaning operation, or the like can be used.

  In addition, for example, in the case where the irregularities formed by the discharge agent discharged by the inkjet method are made into a fibrous body, a drug that dissolves, contracts, or decomposes part of the skin contact surface of the action region 10 (so-called extraction). A method of forming a three-dimensional fibrous structure having irregularities by depositing an ink containing a (corrosive) by an inkjet method can be used (see Patent Document 6 above).

  The form of the pattern formed by inkjet printing is not particularly limited, and examples thereof include a striped pattern, a lattice pattern, a mesh pattern, or a combination of these.

  FIG. 4 is a diagram showing an example of a pattern formed by coating by spraying paint and / or powder. Here, a case where the fibrous body 20 is formed by the inkjet ink for textile printing itself is shown.

  4 (A) to 4 (D) are striped patterns, (A) is a pattern in which fibrous bodies 20 are arranged in parallel at regular intervals, and (B) is a plurality of fibrous bodies 20 having different line widths. A pattern arranged in parallel at regular intervals, (C) is a repeating pattern of parallel stripes from a wide fibrous body 20 to a narrow fibrous body 20, (D) is a fibrous body consisting of wavy lines A pattern in which 20 are arranged in parallel at regular intervals and a pattern in which fibrous bodies 20 made of zigzag lines are arranged in parallel at regular intervals are separately arranged in one action region.

  4 (E) to 4 (H) are fibrous patterns exhibiting a lattice pattern, (E) is a pattern in which a plurality of quadrangles are partitioned by the fibrous body 20, and (F) is a plurality of parallelograms having a fibrous body. (G) is a pattern in which a plurality of triangles are partitioned by the fibrous body 20, and (H) is a pattern in which a plurality of hexagons and triangles are partitioned by the fibrous body 20.
