  In recent years, due to the development of swimwear technology, the required performance for swimwear is increasing, and for example, swimsuits for swimming are required to have higher adhesion to swimwear wearers. From such a point, for example, a swimsuit provided with an anti-slip material having a higher anti-slip effect is required for the swimsuit disclosed in Patent Document 1.

  This invention is made | formed in view of the said situation, The objective is to provide the swimsuit provided with the anti-slip | skid material which has a high anti-slip | skid effect.

  The swimsuit of the present invention capable of solving the above-described problem includes an anti-slip material having a woven fabric formed by using a yarn containing nanofibers having a fiber diameter of 1 μm or less as either a warp or a weft. It has the characteristics in the place. The swimsuit of the present invention includes an anti-slip material having a woven fabric formed by using a yarn containing nanofibers as either a warp or a weft, so that the swimsuit adheres to the skin of the wearer and fits. Sexuality is enhanced. Further, since the woven fabric is configured by using the yarn containing nanofibers for either one of the warp and the weft, the anti-slip material having the woven fabric has sufficient durability. Therefore, even if a non-slip material is attached to a highly stretchable material such as a swimsuit, the anti-slip material is not easily broken, and even if the anti-slip material is used in a situation where it rubs against the skin etc., the nanofiber is difficult to break. Become.

  The anti-slip material is preferably provided on the inner surface of the swimsuit along the edge of the opening of the swimsuit. If the anti-slip material is provided in this manner, the end of the swimsuit is in close contact with the wearer's skin and the like, and the end of the swimsuit is less likely to be displaced or drowned.

  In the woven fabric, it is preferable that the warp is composed of yarn containing nanofibers, and the weft is composed of yarn formed of fibers having a fiber diameter of 2 μm or more. If the warp of the woven fabric is composed of yarns containing nanofibers, the nanofibers are less likely to be cut during the production of the woven fabric, and the anti-slip material tends to have a good anti-slip effect.

  In the woven fabric, it is preferable that warp yarns protrude more on the inner surface of the swimsuit than the weft yarns. If the anti-slip material is made of such a woven fabric, the yarn containing nanofibers comes into more contact with the wearer's skin and the like, and the anti-slip effect of the anti-slip material is enhanced.

  The yarn containing the nanofibers is preferably oriented along the edge of the opening of the swimsuit. If the yarn containing the nanofibers is oriented along the edge of the opening of the swimsuit, the yarn containing the nanofibers is oriented substantially perpendicular to the direction in which the end of the swimsuit falls, and the yarn containing the nanofibers The anti-slip effect by increases.

  The anti-slip material is provided, for example, in contact with the wearer's skin. In this case, the anti-slip material acts so as to enhance the adhesion and fit of the swimsuit to the wearer's skin.

  The swimsuit of the present invention is composed of an upper garment member worn on the upper body and a lower garment member worn on the lower body, and the anti-slip material contacts the lower garment member when the swimsuit is worn on the inner surface of the upper garment member. It may be provided. Such a swimsuit is preferably used for a woman who wants to suppress exposure of the abdomen because the upper garment member is difficult to roll up. Moreover, when exercising with a swimsuit, the upper garment member is less likely to be rolled up, making it easier to exercise.

  The upper garment member may have an exterior part and an interior part that is attached to the inner side surface of the exterior part and extends downward from the hem of the exterior part. At this time, it is preferable that the anti-slip material is provided on the inner surface of the exterior portion so as to come into contact with the lower garment member when the swimsuit is worn. Thus, when the upper garment member has a double structure of an exterior part and an interior part, the anti-slip | skid material may be provided in the inner surface of the exterior part. Also in this case, by providing the anti-slip material, the outer part of the upper garment member is hardly rolled up.

  The swimsuit of the present invention includes an anti-slip material having a woven fabric formed by using a yarn containing nanofibers as either a warp or a weft, so that the swimsuit adheres to the skin of the wearer and fits. Sexuality is enhanced. In addition, since the anti-slip material has sufficient durability, even if the anti-slip material is attached to a highly stretchable material such as a swimsuit, the anti-slip material is not easily broken, and the anti-slip material is Nanofibers are difficult to cut even when used in a situation where they are rubbed.

The schematic of a one-piece type swimsuit is shown as one embodiment of the swimsuit of the present invention. The schematic of a spats type swimsuit is shown as one embodiment of the swimsuit of the present invention. The schematic of a two-piece type swimsuit is shown as one embodiment of the swimsuit of the present invention. The modification of the upper garment member of the swimsuit shown in Drawing 3 is expressed.

  The swimsuit of the present invention is provided with an anti-slip material. The anti-slip material is provided on the inner surface of the swimsuit, that is, the surface on the side facing the wearer's skin when the swimsuit is worn. Since the swimsuit of the present invention is provided with an anti-slip material, the fit of the swimsuit to the wearer is enhanced, and the swimsuit is less likely to shift during swimming.

  The shape of the swimsuit of the present invention is not particularly limited. Men's swimsuits include briefs, trunks, spats, etc. Women's swimsuits include one-piece, two-piece (for example, bikini, tank top bikini, and separates). .

  The mounting position of the non-slip material is not particularly limited as long as it is provided on the inner surface of the swimsuit. The anti-slip material is provided so as to be in contact with the wearer's skin, for example. In this case, the anti-slip material acts so as to enhance the adhesion and fit of the swimsuit to the wearer's skin. In the case where the swimsuit is composed of two or more separated members and one of the members is worn so as to overlap the other member, the anti-slip material is placed on the inner surface of the one member on the other member. It may be provided at a position in contact with. In this case, the anti-slip material acts to increase the adhesion of one member to the other member, and as a result, the one member is less likely to roll up or shift.

  The anti-slip material is preferably provided on the inner side surface of the swimsuit along the edge of the opening of the swimsuit. Swimwear openings include leg openings through which the wearer's legs pass, waist opening through the wearer's torso, arm openings through the wearer's arm, and neck around the wearer's neck (head) An opening etc. are mentioned. Furthermore, the opening part of a swimsuit is not restricted to the part which passes a part of a wearer's body, For example, the opening formed in the back of a swimsuit is also contained. For example, in the case of a swimsuit worn by lacing like a bikini-type swimsuit, an opening formed by lacing corresponds to the opening of the swimsuit. If anti-slip material is provided on the inner surface of the swimsuit along the edge of the swimsuit opening, the end of the swimsuit will be in close contact with the wearer's skin, etc. Become. When the anti-slip material is provided along the edge of the opening of the swimsuit, the anti-slip material may be provided with a width of about 3 mm to 50 mm.

  The anti-slip material provided in the swimsuit of the present invention has a woven fabric configured by using a yarn containing nanofibers having a fiber diameter of 1 μm or less as either a warp or a weft. Hereinafter, the “yarn containing nanofiber” may be referred to as “nanofiber yarn”.

  In the present invention, nanofiber means a fiber having a fiber diameter of 1 μm or less. The “fiber diameter” of the nanofiber means the diameter of a single fiber. When the cross-sectional shape of the single fiber is an irregular cross-section, the average value of the diameters of the circumscribed circle and the inscribed circle of the irregular cross-section of the single fiber is defined as the fiber diameter. The fiber diameter of the nanofiber is preferably 900 nm or less, and more preferably 800 nm or less. The lower limit of the fiber diameter of the nanofiber is not particularly limited, but the fiber diameter of the nanofiber is preferably 100 nm or more, and more preferably 200 nm or more from the viewpoint of ease of production of the nanofiber.

  The kind of nanofiber is not particularly limited, and recycled fiber such as rayon, semi-synthetic fiber such as acetate, or synthetic fiber can be used. When the nanofiber is a synthetic fiber, examples of the material of the nanofiber include polyesters such as polyethylene terephthalate, polytrimethylene terephthalate, and polybutylene terephthalate; polyamides such as nylon 6 and nylon 66, and the like. The cross-sectional shape of the nanofiber is not particularly limited, and examples thereof include a circle, an ellipse, a polygon, and a star.

  In the present invention, a plurality of nanofibers are bundled to form a yarn for forming a woven fabric. That is, the nanofiber is arranged in the woven fabric as a multifilament yarn. In the multifilament yarn containing nanofibers, the number of nanofibers in the cross section of the yarn is preferably 500 to 20000, and more preferably 1000 to 15000. The multifilament yarn containing nanofibers may contain fibers having a larger fiber diameter than nanofibers. Multifilaments containing nanofibers can be produced, for example, according to the methods described in JP-A-2005-325494 and JP-A-2007-9339.

  The fineness of the multifilament yarn containing nanofibers is not particularly limited, but the fineness is preferably 10 dtex or more, more preferably 20 dtex or more, preferably 500 dtex or less, and more preferably 300 dtex or less. If the multifilament yarn containing nanofibers has such a fineness, the multifilament yarn has an appropriate strength, and a woven fabric can be easily formed from the multifilament yarn.

  The anti-slip material composed of the nanofiber yarn has a large specific surface area of the fiber and a large number of fiber gaps. Therefore, the anti-slip material composed of the nanofiber yarn has a high adsorptivity to the skin and the like and exhibits a high anti-slip effect. However, nanofibers have very small fiber diameters, so the strength of the fibers themselves is weak, and if the structure of the anti-slip material is not devised, a lot of nanofiber fragments will peel off from the anti-slip material, or the anti-slip material will have sufficient durability There is a risk that it will not have sex. Furthermore, there is a possibility that the touch of the anti-slip material may be deteriorated by cutting the nanofibers. For example, when a non-woven fabric is formed from nanofibers, each nanofiber breaks and the surface of the non-woven fabric tends to fluff. In other words, when using non-woven fabric formed from nanofibers as an anti-slip material, the anti-slip material feels worse, or the fiber gaps between nanofibers are less likely to be formed. The stopping effect tends to decrease.

  Therefore, in the present invention, a woven fabric is formed using nanofiber yarns, and this woven fabric is used as an anti-slip material. By using nanofibers in this way, each nanofiber is difficult to break and the nanofibers are likely to exist as long fibers, and the fiber gaps of the nanofibers are well formed, and slipping of the anti-slip material is prevented. The stopping effect is enhanced. Furthermore, by using the nanofiber yarn for either one of the warp and weft of the woven fabric, the anti-slip material has sufficient durability. That is, even if the anti-slip material is attached to a highly stretchable material such as a swimsuit, the anti-slip material is difficult to break. Further, even when the anti-slip material is used in a situation where it rubs against the skin or the like, the nanofibers are difficult to cut.

  The woven structure of the anti-slip material is not particularly limited, and a known woven structure may be employed. Examples of the woven fabric include plain weave, twill weave and satin weave. The woven fabric may be composed only of nanofiber yarns, or may be composed of nanofiber yarns and yarns not containing nanofibers.

  Specifically, in the woven fabric constituting the anti-slip material, one of the warp and the weft is constituted by a nanofiber yarn, and the other is constituted by a yarn not containing the nanofiber. Preferably, the other of the warp and the weft is composed of a yarn formed of fibers having a fiber diameter of 2 μm or more (more preferably 5 μm or more, and further preferably 10 μm or more). In addition, the thread | yarn formed from the fiber whose fiber diameter is 2 micrometers or more means the thread | yarn formed substantially only from the fiber whose fiber diameter is 2 micrometers or more. The yarn formed from a fiber having a fiber diameter of 2 μm or more may be a monofilament yarn or a multifilament yarn, but the yarn formed from a fiber having a fiber diameter of 2 μm or more is a multifilament yarn. It is preferable for enhancing the anti-slip effect.

  The nanofiber yarn is preferably used as a warp for a woven fabric. More preferably, the warp is composed of nanofiber yarns, and the weft is composed of yarns formed of fibers having a fiber diameter of 2 μm or more. If the warp is composed of nanofiber yarns, the nanofibers are less likely to be cut during the production of the woven fabric, and the antiskid material tends to have a good antiskid effect.

  When the warp is composed of nanofiber yarns, it is preferable that the warp yarns protrude more on the inner surface of the swimsuit than the weft yarns. Specifically, when the anti-slip material is viewed from the inner surface of the swimsuit, the number of warps straddling over the wefts (number of wefts) is less than the number of passing under the wefts (number of wefts). Preferably there is. That is, a woven structure in which m / n> 1 is preferable, where m is the number of warps straddling the weft and n is the number of warps passing under the weft, and m / n ≧ 2. More preferred is a woven structure. Such weaving structures include twills (2/1 twills), four weaves (3/1 twills), etc .; five-ply satin weave, eight-ply satin weave, ten-ply weave Examples include satin weaving such as satin weaving. If the anti-slip material is composed of such a woven fabric, the nanofiber yarn comes into more contact with the wearer's skin and the like, and the anti-slip effect of the anti-slip material is enhanced.

  When the warp is composed of nanofiber yarn, the warp yarn may include a yarn not containing nanofiber in addition to the nanofiber yarn. For example, an elastic yarn may be used as a yarn not containing nanofibers used for warp. Examples of the elastic yarn include polyurethane yarn. If the warp is composed of a nanofiber yarn and an elastic yarn, the elastic yarn contracts, so that the nanofiber yarn is relaxed and lifted, and the anti-slip effect by the nanofiber yarn is enhanced. In addition, in order to ensure the strength in the orientation direction of the warp of the woven fabric, the warp includes a general yarn (for example, a yarn formed from fibers having a fiber diameter of 2 μm or more) in addition to the nanofiber yarn. It may be.

  In addition to the nanofiber yarn, when a yarn not containing nanofiber is used as the warp yarn, the warp yarn may be doubled and used on the front side and on the back side. For example, it is preferable to use nanofiber yarns as warp yarns (surface warp yarns) that often appear on the inner surface of the swimsuit, and use yarns that do not contain nanofibers as warp yarns (back warp yarns) that often appear on the surface facing the swimsuit body. . By configuring the warp in this way, it is possible to configure the woven fabric so that a large amount of nanofiber yarns appear on the inner surface of the swimsuit while using yarns that do not contain nanofibers in the warp.

  The nanofiber yarn is preferably oriented along the edge of the opening of the swimsuit. If the nanofiber yarn is oriented along the edge of the opening of the swimsuit, the nanofiber yarn will be oriented substantially perpendicular to the direction in which the end of the swimsuit falls, and the anti-slip effect of the nanofiber yarn is enhanced. It is done. More preferably, nanofiber yarn is used as the warp of the woven fabric, and the warp (ie nanofiber yarn) is oriented along the edge of the swimsuit opening.

  The anti-slip material has a woven fabric composed of nanofiber yarns, but may have other members. For example, the anti-slip material may be formed by laminating a woven fabric composed of nanofiber yarns on another sheet member. In this case, an anti-slip material made of a laminate is attached to the swimsuit so that the woven fabric composed of the nanofiber yarn contacts the skin or the like.

  The non-slip material is configured as follows, for example. The anti-slip material is composed of a woven fabric using nanofiber yarn as warp. The nanofiber yarn is formed from about 8400 nanofibers having a fiber diameter of about 700 nm and has a fineness of about 110 dtex. For the warp of the woven fabric, a polyester yarn having a fineness of about 110 dtex and a polyurethane yarn having a fineness of about 940 dtex are used, a nanofiber yarn is used as a surface warp, and a polyester yarn and a polyurethane yarn are used as a back warp. A polyester yarn having a fineness of about 80 dtex is used for the weft of the woven fabric. Both polyester yarns and polyurethane yarns other than nanofiber yarns are formed from fibers having a fiber diameter of 2 μm or more. The woven fabric is formed by the warp nanofiber yarn straddling five weft yarns and one underneath the weft yarn, so that more nanofiber yarns are exposed on the inner surface of the swimsuit. Will be placed.

  Next, a configuration example of the swimsuit of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments shown in the drawings.

  FIG. 1 shows a schematic view of a one-piece type swimsuit. The swimsuit 1 has a leg opening through which the wearer's leg passes, a neck opening through which the wearer's head passes, and an arm opening through which the wearer's arm passes. The swimsuit 1 shown in FIG. 1 has an anti-slip material 3 along the edge 2 of the leg opening, an anti-slip material 5 along the edge 4 of the neck opening, and an edge 6 of the arm opening. An anti-slip material 7 is provided. These anti-slip materials 3, 5, 7 preferably have a woven fabric formed by using a yarn containing nanofibers having a fiber diameter of 1 μm or less as either a warp or a weft.

  FIG. 2 shows a schematic diagram of a spats-type swimsuit. The swimsuit 11 has a leg opening through which the wearer's leg passes and a trunk periphery opening through which the wearer's trunk passes. The swimsuit 11 shown in FIG. 2 is provided with an anti-slip material 13 along the edge 12 of the leg opening and an anti-slip material 15 along the edge 14 of the waist opening. These anti-slip materials 13 and 15 preferably have a woven fabric formed by using a yarn containing nanofibers having a fiber diameter of 1 μm or less as either a warp or a weft.

  The swimsuit shown in FIGS. 1 and 2 is provided so that the anti-slip material is in contact with the wearer's skin. By providing the anti-slip material in this way, it is expected that the adhesion and fit to the wearer of the swimsuit will be enhanced, the resistance when swimming will be low, and the swim will be fast.

  On the other hand, an embodiment in which an anti-slip material is provided on one member of the two-piece swimsuit and the anti-slip material is provided so as to contact the other member of the two-piece swimsuit will be described with reference to FIGS. 3 and 4. .

  FIG. 3 shows a schematic view of a so-called separate swimsuit among the two-piece swimsuits. The swimsuit 21 is composed of an upper garment member 22 worn on the upper body and a lower garment member 23 worn on the lower body. When the swimsuit 21 is not worn, the upper garment member 22 and the lower garment member 23 are separated from each other. However, when worn, the swimsuit 21 overlaps the lower garment member 23 around the waist of the wearer. To be worn. That is, the swimsuit 21 is worn so that the upper garment member 22 overlaps a part of the lower garment member 23 (the upper end portion of the lower garment member 23). Therefore, when the skirt of the upper garment member 22 is rolled up, the wearer's abdomen is exposed.

  On the inner surface of the upper garment member 22, an anti-slip material 25 is provided along the edge of the waist opening, that is, the hem 24. And the anti-slip | skid material 25 is provided so that the lower garment member 23 may be contact | connected when a swimsuit is worn. The swimsuit 21 provided with the anti-slip material 25 as described above is preferably used for a woman who wants to suppress the abdomen exposure because the upper garment member 22 is difficult to roll up. In addition, when exercising with the swimsuit 21 (including exercise on land and walking exercise in water), the skirt 24 of the upper garment member 22 is less likely to be rolled up, making it easier to exercise.

  Conventionally, in the so-called separate swimsuit as shown in FIG. 3, an anti-slip material has not been provided on the inner surface of the upper garment member at a position where it comes into contact with the lower garment member when the swimsuit is worn. Therefore, a conventionally known elastic body such as natural rubber, silicone, polyurethane, or the like may be used as an anti-slip material provided on the inner surface of the upper garment member. However, in order to have a higher anti-slip effect, it is preferable to use a woven fabric, a knitted fabric, or a non-woven fabric made of yarn containing nanofibers with a fiber diameter of 1 μm or less as the anti-slip material. It is more preferable to use a woven fabric composed of yarns containing nanofibers having a fiber diameter of 1 μm or less, and a woven fabric constructed using yarns containing nanofibers having a fiber diameter of 1 μm or less as either warp or weft More preferably, it is used.

  FIG. 4 shows a modified example of the upper garment member of the separate swimsuit shown in FIG. The upper garment member 22 shown in FIG. 4 has a double structure of an exterior part 26 and an interior part 27. Specifically, the upper garment member 22 includes an exterior portion 26 and an interior portion 27 that is attached to the inner surface of the exterior portion 26 and extends below the hem 28 of the exterior portion 26. The interior portion 27 is joined to the exterior portion 26 at a predetermined range from the upper end. In addition, in FIG. 4, although the upper end of the interior part 27 is located near a wearer's chest, the position of the upper end of the interior part 27 is not limited to this. On the other hand, the exterior portion 26 is not joined to the interior portion 27 in a predetermined range from the hem (lower end) 28, and the skirt 28 exists as a free end of the exterior portion 26 and can be rolled. The bottom 29 of the interior part 27 is located below the bottom of the exterior part 26. In order to wear the upper garment member 22 shown in FIG. 4, the inner portion 27 of the upper garment member 22 is placed inside the lower garment member, that is, between the skin of the wearer and the lower garment member, and the outer portion 26 of the upper garment member 22. Is placed on the outside of the lower garment member.

  The upper garment member 22 shown in FIG. 4 is provided on the inner surface of the exterior portion 26 so that the anti-slip material 30 contacts the lower garment member when wearing a swimsuit. By providing the anti-slip material 30 in this way, the skirt 28 of the exterior portion 26 of the upper garment member 22 is less likely to be rolled up. Thus, when the upper garment member has a double structure of the exterior part and the interior part, the anti-slip material is provided on the inner surface of the exterior part as the anti-slip material provided on the inner surface of the swimsuit (upper member). It may be.

  In the upper garment member shown in FIG. 4 as well, a conventionally known elastic body such as natural rubber, silicone, polyurethane or the like may be used as an anti-slip material provided on the inner surface of the exterior part. However, in order to have a higher anti-slip effect, it is preferable to use a woven fabric, a knitted fabric, or a non-woven fabric made of yarn containing nanofibers with a fiber diameter of 1 μm or less as the anti-slip material. It is more preferable to use a woven fabric composed of yarns containing nanofibers having a fiber diameter of 1 μm or less, and a woven fabric constructed using yarns containing nanofibers having a fiber diameter of 1 μm or less as either warp or weft More preferably, it is used.
