Description

[Technical Field]

[0001] The present invention relates to clothing such as underwear such as shirts and pants, socks, and stockings made of knitted fabrics, which have openings such as the bottom of a shirt, the leg openings of pants, the waist of stockings, and leg sections that cover the legs but do not have foot sections to cover the feet but have a bottom opening for inserting the feet, and more particularly to lower-body clothing such as leggings that have a panty section that covers the abdomen and buttocks and leg sections that extend from below the knee to the ankles and have a bottom opening for inserting the feet. Note that leggings, as mentioned above, are similar to pantyhose in shape but do not have foot sections that cover the feet from the ankles to the toes, and the lower-body clothing according to the present invention is not limited to leggings as long as they have a bottom opening for inserting the feet from the ankles to the toes because they do not have foot sections. [Background technology]

[0002] For example, there is a method of knitting a hem using a circular knitting milling machine that is suitable for producing knitted fabrics such as underwear. Generally, in a cylinder-dial type circular knitting milling machine, when producing knitted fabrics such as underwear, all of the multiple yarn feeders arranged in the circumferential direction are used for knitting the body, cotton yarn is supplied from these yarn feeders to needles, and the needles are driven by cylinder cams and dial cams arranged corresponding to each yarn feeder to continuously knit the knitted fabric.

[0003] This method allows knitted fabrics to be knitted efficiently, but when manufacturing camisoles, shorts, etc., it is necessary to cut the knitted fabric, fold the bottom end into a bag-like shape, and sew it to form a so-called double hem portion (bag-knitted portion).

[0004] Such underwear has a thick hem, which creates a difference in level between the body and hem, which can cause discomfort to the skin when worn and can be visible through outerwear.

[0005] For example, in Japanese Patent No. 4139880 (Patent Document 1), the hem of a foundation such as a girdle, which is the opening through which the legs are exposed, is made of elastic knitting and is double welted (hollow knit) with makeup knitting. Also, the waist part, which is the opening of the panty part that covers the abdomen and buttocks, is made of a tightening fabric with elastic thread inserted, and is doubled and sewn with double welt (hollow knit) (paragraph 0012 of Patent Document 1). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent No. 4139880 Summary of the Invention [Problem to be solved by the invention]

[0007] However, as disclosed in the above-mentioned Patent Document 1, when openings such as the hem are made with the conventional double welt (hollow knit), the fabric becomes thicker than the body, making the seam stand out and making it difficult to coordinate with other garments.In particular, for high-gauge leggings (which are knitted so tightly that the stitches are not noticeable, giving a neat impression and making them easy to coordinate), the hem is made with a neat single welt (single hem) to prevent the hem from rolling up.This is an example of extremely delicate and comfortable lower-body clothing that could not be realized with conventional knit fabrics.

[0008] The present invention was developed in view of the above-mentioned problems of the prior art, and its purpose is to provide lower body clothing (leggings, for example) that is extremely delicate and extremely comfortable to wear, which has a panty portion that covers the abdomen and buttocks and a leg portion that covers the legs, but does not have a foot portion that covers the feet, the leg portion is long enough to extend from below the knee to the ankle, and the feet come out from the hems of the leg portion, and the hems of the leg portion are single welted to prevent the hems from rolling up. [Means for solving the problem]

[0009] In order to achieve the above object, the lower body garment according to the present invention employs the following technical means.

[0010] In other words, the lower-body garment of the present invention comprises a panty portion that covers the abdomen and buttocks and a leg portion that covers the legs, but does not comprise a foot portion that covers the feet, the length of the leg portions is between below the knee and the ankles, and the feet emerge from the hem portion at the lower end of the leg portions, the hem portion of the leg portions is not tubular knitted, the lower-body garment is knitted from the hem portion, at least a portion of the hem is knitted using a plain knit in which single covering yarn and nylon yarn are plated at two of the four knitting nozzles of the knitting machine, and double covering yarn is supplied and knitted so as to be laid in at two of the four knitting nozzles, and the leg portions are knitted by modifying the double covering yarn that was laid in at two of the four knitting nozzles so that it is knitted in plain knit.

[0011] Preferably, the hem section is composed of a first hem section closer to the hem and a second hem section closer to the leg section, and the first hem section is knitted by supplying a plain knit in which single-covered yarn and nylon yarn are plated at two of the four knitting machine opens, and supplying a lay-in double-covered yarn at two of the four knitting machine opens; the second hem section is knitted by changing the double-covered yarn at one of the two four knitting machine opens from lay-in to plain knit, and changing one of the double-covered yarns that was laid-in at the first hem section closer to the hem to plain knit at the second hem section closer to the leg section.

[0012] More preferably, the nylon yarn used for the ground knitting can be configured to be wooly nylon yarn.

[0013] More preferably, the woolly nylon yarn can be configured as a two-ply yarn. [Effects of the Invention]

[0014] The lower-body garment of the present invention comprises a panty portion that covers the abdomen and buttocks and a leg portion that covers the legs, but does not comprise a foot portion that covers the feet, the leg portion is lengthened from below the knee to the ankle, the legs are extended from the bottom of the leg portion, and the bottom of the leg portion is single welted to prevent the bottom from rolling up, making it possible to provide an extremely delicate and extremely comfortable lower-body garment (typically leggings). [Brief explanation of the drawings]

[0015] [Figure 1] 1 is a schematic front view of leggings according to an embodiment of the present invention. [Figure 2] FIG. 2(A) is an enlarged view of an area 2A in FIG. 1, and FIG. 2(B) is a diagram showing knitting conditions for the knitted fabric in the leg portion and the hem portion. [Figure 3] FIG. 2 is a diagram for explaining a covering yarn used to knit the leggings of FIG. 1. DETAILED DESCRIPTION OF THE INVENTION

[0016] Leggings 1 according to an embodiment of the present invention will be described in detail below with reference to Figs. 1 to 3. These leggings 1 are described as an example of a very delicate and comfortable lower-body garment, with the cuffs of the leg sections where the legs are exposed being single-welted to prevent the cuffs from rolling up. The lower-body garment according to the present invention includes a panty section that covers the abdomen and buttocks and a leg section that covers the legs, but does not include a foot section that covers the feet. The leg sections are lengthened from below the knee to the ankles, and the legs are exposed from the cuffs of the leg sections, a garment typified by leggings. The garment is not limited to either men's or women's wear, and is not limited to outerwear or innerwear. However, like these leggings 1, they are typically lower-body garments that are lengthened from below the knee to the ankles (these leggings 1 are ankle-length) and are often worn as outerwear for women.

[0017] Leggings 1, an example of pants-type lower-body garments that reach the ankles and are primarily worn as outerwear, will be described with reference to Figures 1 to 3. Figure 1 shows a schematic front view of the leggings 1, Figure 2(A) shows an enlarged view of region 2A in Figure 1, Figure 2(B) shows a diagram illustrating the knitting conditions for the knitted fabric in leg portions 3 and hem portions 5, and Figure 3 is a diagram illustrating the covering yarn used to knit the leggings 1.

[0018] The leggings 1 are made by sewing a knitted fabric to form a torso section 2 (a single tubular section that is a panty section that covers the abdomen and buttocks) and two leg sections 3 into which the legs are inserted. The waist portion 4 has a structure in which a waistband is sandwiched and sewn in. It is also preferable to have an all-elastic (all-knit) waist portion 4 without a waistband so as not to constrict the waist. Furthermore, although not limited to this, the leggings 1 have a high rise so that underwear, etc., is not visible even when squatting.

[0019] Note that the leggings described as an example of lower-body garments according to the present invention can have a variety of structures, and even though the lower-body garments according to the present invention are leggings, they are not limited to a specific structure. As long as they have a very delicate and comfortable fit, such as a feature described below in which the hem of the leg portion where the leg is exposed is single-welted to prevent the hem from rolling up, any legging structure and any type of knit fabric or knitting yarn that constitutes the leggings are basically acceptable. Therefore, the structure of the leggings 1 described above is merely an example. Furthermore, even leggings that are not limited to this type are, as mentioned above, merely one example of lower-body garments according to the present invention.

[0020] The knitted fabrics of the leg portions 3 and the hem portions 5 constituting the leggings 1 according to this embodiment will be described in detail below with reference to Figs. 2 and 3.

[0021] As shown in Fig. 2, the legs are inserted through a hem 5 at the bottom of the leg part 3 of the leggings 1. What is distinctive about the leggings 1 is that, as shown in Fig. 2(A) which is an enlarged view of area 2A in Fig. 1, the leggings 1 are provided with a leg part 3 and a hem 5 at the bottom end of the leg part 3 through which the foot (the foot part from the ankle through the heel to the toes) is inserted and removed.

[0022] The hem 5 is made up of, from the leg 3 downwards, a second dividing section 5E which forms the boundary between the leg 3 and the hem 5, a second hem 5D, a first dividing section 5C which forms the boundary between the second hem 5D and the first hem 5B, a first hem 5B, and a lowermost edge section 5A. Note that the second hem 5D area may be made up of the first hem 5B, and the entire hem 5 may be made up of the first hem 5B.

[0023] Here, an example of knitting yarn and knitting will be described. Knitting starts from the bottom edge. ·First hem opening 5B (hem opening side) 1. Double covering thread TD3311 / 5 is laid in. 2nd: Plain knitting with covering yarn TS2211 / 5 and woolly nylon two-ply yarn 21T / 2-20 as plating (plaiting yarn) 3rd hole: Double covering thread TD3311 / 5 laid in (poured) 4: Plain knitting with covering yarn TS2211 / 5 and woolly nylon two-ply yarn 21T / 2-20 as plating (plaiting yarn). Second hem 5D (Leg 3 side) 1. Double covering yarn TD3311 / 5 plain knit 2nd: Plain knitting with covering yarn TS2211 / 5 and woolly nylon two-ply yarn 21T / 2-20 as plating (plaiting yarn) 3rd hole: Double covering thread TD3311 / 5 laid in (poured) 4: Plain knitting with covering yarn TS2211 / 5 and woolly nylon two-ply yarn 21T / 2-20 as plating (plaiting yarn). Leg part 3 (body) 1. Double covering yarn TD3311 / 5 plain knit 2nd: Plain knitting with covering yarn TS2011 / 5 and woolly nylon two-ply yarn 21T / 2-20 as plating (plaiting yarn) 3rd: Plain knitting with double covering yarn TD3311 / 5 4: Plain knitting with covering yarn TS2211 / 5 and woolly nylon two-ply yarn 21T / 2-20 as plating (plaiting yarn).

[0024] where: Covering thread TS2211 / 5 is a single covering thread with a core thread of 22 decitex (20 denier) urethane thread and a five-ply, 11 decitex (10 denier) nylon thread. Woolly nylon two-ply yarn 21T / 2-20 is a two-ply yarn (40 filaments in total) of 21 decitex woolly nylon yarn (20 filaments), Double covering thread TD3311 / 5 is a 33 decitex (30 denier) urethane core thread with a 5-ply 11 decitex (10 denier) nylon wrap. are shown respectively.

[0025] Here, single-covered yarn and double-covered yarn will be described with reference to FIG.

[0026] As shown in FIG. 3(A), single covered yarn (SCY: Single Covered Yarn) 50S is a covered yarn in which a core yarn of a urethane-based elastic yarn (such as the above-mentioned 22-dtex urethane yarn 60) is wound with a wrapped yarn of a non-elastic yarn (such as the above-mentioned 11-dtex nylon yarn 70). Also, as shown in FIG. 3(B), double covered yarn (DCY: Double Covered Yarn) 50D is a covered yarn in which a core yarn of a urethane-based elastic yarn (such as the above-mentioned 33-dtex urethane yarn 60) is wound with a wrapped yarn of a non-elastic yarn (such as the above-mentioned 11-dtex nylon yarn 70). Here, as shown in FIG. 3(B), double covered yarn 50D is in which nylon yarn 70A and nylon yarn 70B, which are examples of non-elastic yarns, are wound twice around a core yarn of urethane yarn 60, with the wound directions being opposite (S twist and Z twist). The nylon yarn used as the wrapping yarn is composed of nylon yarn 70A, which is a first twisted wrapping yarn, and nylon yarn 70B, which is a top twisted wrapping yarn. This double covering yarn, which is wound twice so that the winding directions are opposite (S twist and Z twist), is preferable because there is no twist (direction) and therefore no diagonal rows are generated when knitting a lower-body garment.

[0027] As described above with reference to Figures 1 to 3, the leggings 1 are an example of lower-body garments that include a torso portion (panty portion) 2 that covers the abdomen and buttocks and leg portions 3 that cover the legs, but do not include a foot portion that covers the feet, and the leg portions 3 are between below the knee and the ankles in length, with the legs emerging from hem portions 5 at the lower ends of the leg portions 3. The hem portions 5 of the leg portions 3 are not hollow knitted. Furthermore, knitting begins from the hem portions.

[0028] First, in the first hem section 5B close to the hem, plain knitting is performed in which single covering yarn and nylon yarn are plated at two of the four knitting jaws, and double covering yarn is supplied and knitted so as to be laid in at two of the four knitting jaws.

[0029] Next, in the second hem portion 5D near the leg portion 3, the double covering yarn that had been laid in one of two of the four passes of the knitting machine is changed from lay-in to plain knitting and knitted.

[0030] Next, in the leg section 3, the double covering yarn that had been laid in one of two passes out of four passes of the knitting machine is changed from lay-in to plain knitting and knitted.

[0031] That is, one of the double covering yarns that was laid in two places at the first hem section 5B near the hem is changed to plain knit at the second hem section 5D near the leg 3, and further, the double covering yarn that was laid in one place at the second hem section 5D is changed to plain knit at the second hem section 5D near the leg 3. That is, of the double covering yarns supplied to two of the four places, both places are knitted as lay-in at the first hem section 5B near the hem, one place is changed from lay-in to plain knit at the second hem section 5D near the leg 3, and another place is changed from lay-in to plain knit at the leg 3.

[0032] That is, one of the double covered yarns laid in the first hem section 5B, which is closer to the hem, is changed to plain knit in the second hem section 5D, which is closer to the leg section 3, and the other double covered yarn laid in the second hem section 5D is changed to plain knit and knitted in the leg section 3.

[0033] With this configuration, two DCYs are laid in the first hem section 5B, which is closer to the hem, so a single-welted hem that is not thick can be achieved without double-welting the first hem section 5B, and the two laid-in DCYs can prevent the hem from fraying. One of the double covering yarns laid in the first hem section 5B, which is closer to the hem, is changed to plain knit in the second hem section 5D, which is closer to the leg section 3, so the transition between the leg section 3 and the second hem section 5D can be made less noticeable.

[0034] As mentioned above, the second hem 5D may be made up of the first hem 5B, with the entire hem 5 being made up of the first hem 5B. In this case, the hem is knitted starting from the hem, and the entire hem 5 is knitted using a plain knit in which single-covered yarn and nylon yarn are plated at two of the four knitting machine ends, and double-covered yarn is laid-in at two of the four knitting machine ends. The leg section 3 is knitted using a plain knit in which the double-covered yarn is knitted at two of the four knitting machine ends. In other words, the entire hem 5 is made up of the first hem 5B. Even with this type of hem 5, the hem 5 is not tubular knitted, and two DCY yarns are laid-in, which means that the fabric is not thicker than the body and prevents the hem from being rolled up.

[0035] Here, the nylon yarn used for the ground knitting of the leg portion 3 (which may include the body portion 2) is preferably a woolly nylon yarn, and further, the woolly nylon yarn is preferably a two-ply yarn.

[0036] As described above, the leggings (a representative example of lower-body clothing) according to this embodiment comprise a panty portion that covers the abdomen and buttocks and a leg portion that covers the legs, but does not comprise a foot portion that covers the feet, the length of the leg portion is between below the knee and the ankle, and the legs are exposed from the bottom of the leg portion, and the bottom of the leg portion is single welted to prevent the hem from rolling up, making it possible to provide lower-body clothing that is extremely delicate and extremely comfortable to wear.

[0037] It should be noted that the embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. The scope of the present invention is defined by the claims, not by the above description, and is intended to include all modifications within the meaning and scope of the claims. [Industrial Applicability]

[0038] The present invention is particularly preferred in that it can provide lower body clothing (typically leggings) that is extremely delicate and extremely comfortable to wear, with a panty portion that covers the abdomen and buttocks and a leg portion that covers the legs, but does not have a foot portion that covers the feet, and the leg portion is long enough to extend from below the knee to the ankle, with the legs coming out from the bottom of the leg portion, and the bottom of the leg portion is single welted to prevent the hem from rolling up.
