Description

  The present invention relates to a garment in which a shirt hem, a pant foot, a stocking waist, and the like are knitted into a bag for underwear such as shirts and pants and socks and stockings formed by molding.

  As a conventional technique, in underwear such as shirts and pants formed by molded knitting, socks and stockings, the bottom of shirts, pants feet, waist of stockings, etc. are knitted into a bag knitting (Make- up) Processing of clothing openings by knitting is known. (Patent Document 1 and Patent Document 2)

  FIG. 15 is a perspective view showing a cross section of a main part in the body length direction of a pant knitted by a conventional cylindrical forming circular knitting machine, wherein 70 is a body part, 71 is a waist part, and 72 is the waist part. Reference numeral 71 denotes a bag knitting portion, 75 denotes a skirt portion, 76 denotes a bag knitting portion of the skirt portion 75, and 77 denotes a connecting portion of the upper edge of the bag knitting portion 76 of the skirt portion 75.

  The make-up knitting of the skirt 75 is as follows.

  The problem to be solved is that the knitting end edge knitting part, the bag knitting part and the body part are integrally sewn by over-sewing etc. over the entire circumference of the hem, so that the sewing part is convex. And the feeling of wearing is reduced because the touch of the sewn part is poor. Furthermore, sewing together the knitting end edge knitting part, the bag knitting part and the body part requires extra sewing work, which leads to a decrease in production efficiency, resulting in improvements in quality and efficiency. That is not enough.

The present invention relates to a garment having an opening that is knitted one by one by a circular knitting machine, the knitting end portion of the opening portion is constituted by a bag knitting, and the knitting end edge knitting portion of the bag knitting is heat-sealed. The heat-fusible elastic yarns are heat-sealed at the intersections of the knitting loops by knitting the elastic elastic yarns and further heat treatment by wet heat or dry heat.
Here, the heat-fusible elastic yarn is heat-bonded to each other by heat treatment by wet heat or dry heat, and has high stretchability (elasticity) without losing stretchability (elasticity) at the heat-welded portion. An elastic yarn having
The heat-fusible elastic yarn is preferably knitted over 2 to 10 courses of the knitting end edge knitted portion of the bag knitting, and more preferably knitted over 3 to 6 courses. .

Further, according to the present invention, the flat knitted fabric knitted by the circular knitting machine tends to curl easily due to the characteristics of the knitting structure, and also curls at the knitting end edge knitting portion of the bag knitting. The heat-sealable elastic yarns are knitted inside and heat-treated to heat-seal the heat-sealable elastic yarns facing each other.
The heat-fusible elastic yarn is preferably knitted over 2 to 10 courses inside the knitting end edge knitting portion of the bag knitting by plating knitting, and knitted over 3 to 6 courses. More preferably.

  According to the present invention, in the garment, a heat-fusible elastic yarn is knitted into the knitting end edge knitted portion of the bag knitting, and a non-heat-sealing covering elastic yarn is further knitted by adding 1 to 3 courses. It is a feature. As a result, the stitches at the knitting end edge knitting portion become dense, and the most easily unraveled end end curls inward due to its stretchability, making it even more difficult to unravel.

  The present invention provides a knitted loop knitted with a heat-fusible elastic yarn in a knitting end edge knitting portion of a bag knitting portion as described above and knitted with the heat-fusible elastic yarn through heat treatment by wet heat or dry heat. The heat-bonding elastic yarns are heat-sealed together at the intersection of the knitted fabric, and the knitting end edge knitted portion, the bag knitted portion and the body portion are spread over the entire circumference of the hem as in the past. Eliminating the need to sew together eliminates the feeling of touch due to the convex sewing site, improving the feeling of wearing and eliminating the needless conventional sewing process, improving production efficiency. It is done. In addition, by using heat-fusion elastic yarns, the heat-sealed part does not harden like ordinary fusion yarns, and because it is rich in elasticity, it feels soft when worn and follows the body well. An excellent wearing feeling is obtained.

  Furthermore, by knitting a heat-fusible elastic yarn inside the knitting end edge knitting portion of the curled bag-like knitting, and further heat-fusing the heat-fusing elastic yarns facing each other, further prevention of unraveling can be achieved. Not only is it strong, but the curled knitting end edge knitted portion is flat, so that the bulkiness is suppressed. Further, since the heat-sealed portion is inside the curled knitting end edge knitted portion and is not exposed to the skin side, excellent appearance and comfort can be obtained.

  According to the present invention, in a garment knitted one by one by a cylindrical molding circular knitting machine and having an opening portion, the opening portion is constituted by a bag knitting, and the knitting end edge knitting portion of the bag knitting portion is provided. A heat-fusible elastic yarn is knitted at the part, and the elastic yarn is heat-sealed at the intersection of the stitches by heat treatment with wet heat or dry heat, or the knitting loops facing each other are heat-sealed. In the following, description will be made with reference to the drawings. 1 is a pant, 2 is a front body, 3 is a back body, 5 is a waist formed by a bag knitting portion 6, 7 is a skirt formed by a bag knitting portion 8, and 9 is formed by a crotch fabric 10. The crotch portions 11 and 12 are bag knitted portions provided at both ends of the crotch fabric 10, and 13 is a tubular knitted fabric, which is knitted one by one by a cylindrical molding circular knitting machine. The front body 2 and the back body 3 are knitted integrally with the molded circular knitted fabric of the pants 1. Furthermore, bag knitting parts 6 and 8 of the waist part 5 and the skirt part 7 are knitted on the upper and lower edges of the molded circular knitted fabric, respectively. Further, the crotch fabric 10 of the pants 1 is also knitted with a molded circular knitted fabric, and 11 and 12 are bag knitted portions having the same knitting structure as the hem portion 7, respectively.

  In FIG. 4, 15 is a connecting portion provided at the upper end of the bag knitting portion 8 of the skirt portion 7, 18 is a knitting end edge knitting portion of the bag knitting portion 8, and the knitting end edge knitting portion 18 is a flat knitting course. It is organized. In addition, as the thread use of the flat knitting course, it is designed to be appropriately knitted, such as plating knitting with ground yarn and heat-fusible elastic yarn, and as the ground yarn, nylon fiber, polyester fiber, etc. A synthetic fiber is used, or an appropriate blended yarn of natural fiber such as cotton or natural fiber and synthetic fiber is used.

  Furthermore, as the heat-fusible elastic yarn, polyurethane-based synthetic fiber is used, and it is excellent in stretchability (elasticity), and the heat-fusible elastic yarns are heat-bonded to each other, and in the heat-welded part, A material having a high degree of elasticity (elasticity) without losing elasticity (elasticity) is used. In addition, as heat-bondable elastic yarns, LYCRA T-178C manufactured by Operontex Co., Ltd. (“Lycra” is a registered trademark of Invista), Leuka SF manufactured by Asahi Kasei Fibers Co., Ltd. (“Royka” is a registered trademark of Asahi Kasei Fibers Co., Ltd.) ), Nisshinbo Co., Ltd. Mobilon RL ("Mobilon" is a registered trademark of Nisshinbo Co., Ltd.) is known.

  The knitting end edge knitting portion 18 of the bag knitting portion 8 is preferably knitted with a flat knitting by a plating knitting using a ground yarn and a heat-fusible elastic yarn. In addition, as means for heat-treating a flat knitted fabric with heat-fusible elastic yarn, there are wet heat treatment with steam or hot water, heat treatment with hot air drying, etc. It is more preferable because it leads to reduction.

  In addition, the knitting structure of the bag knitting parts 11 and 12 provided in the both ends of the bag knitting parts 6 and 8 of the waist part 5 and the skirt part 7 of the pants 1 and the crotch fabric 10 is knitted with the same knitting structure. However, application examples of the knitting structure of the present invention will be described below for the bag knitting portions 6 and 8, that is, the bag knitting portion 8 of the skirt portion 7.

  A first application example is shown in FIGS. Following the connecting portion 15 in the bag knitting portion 8 of the hem portion 7, three courses of flat knitting loops 20, 21, 22 for preventing unraveling are knitted, and the flat knitting loops 20, 21, 22 are knitted yarns 50, 51 is knitted by a known plating knitting or the like. 5 and 8, flat knitting loops 20 to 22 for preventing unwinding are immediately knitted from the connecting portion 15, but the knitted fabric similar to the bag knitting portion 8 continues from the connecting portion 15. The flat knitted loops 20 to 22 can be knitted later.

  Further, as the yarn of the knitting yarn 50, a polyurethane elastic fiber of about 110T (decitex, the same applies hereinafter) that is heat-fusible and rich in stretch elasticity is used. On the other hand, as the yarn of the knitting yarn 51, 44T / 2 ( Twin yarn) nylon fiber can be used. The material of the knitting yarn 51 is not particularly limited as long as it has the strength to maintain the flat knitted loop portion for preventing unraveling, but the material dyed in the same manner as the body fabric in the dyeing process does not become uneven dyeing. It is suitable in appearance.

  After the above knitting, by performing an appropriate heat treatment, the polyurethane elastic fibers 50 are fixed to each other at the intersections of the knitting loops 20, 21, and 22 by the knitting yarns 50 and 51 as shown in FIG. Unbreaking processing is performed. Moreover, since the heat-sealed part of each knitted loop is excellent in elasticity (elasticity), it has good flexibility and does not impair the wearing feeling. Further, unlike the conventional case, it is not necessary to integrally sew the bag knitting portion 8 of the hem portion 7, so that the production efficiency is improved, and a garment having excellent quality, efficiency, wearing feeling and the like can be obtained.

  A second application example is shown in FIGS. 6, 9, 11, and 12. In the same manner as in Application Example 1, following the connecting portion 15 in the bag knitting portion 8 of the hem portion 7, five courses of unraveling flat knitting loops 25, 26, 27, 28 and 29 are knitted, and the knitting yarn 50 11, the knitting loop of the knitting yarn 51 appears on the loop outer side (skin side) of the knitting end edge knitting portion 18 and the knitting yarn 50 on the inner side of the loop, as shown in FIG. The knitting loop is knitted so as to be positioned. In addition, as the yarn of the knitting yarns 50 and 51, the same material as that of the application example 1 can be used.

  After the above knitting, the polyurethane elastic fibers 50 are heat-bonded to each other at each intersection of the knitting loops 25, 26, 27, 28, and 29 by the knitting yarns 50 and 51 as shown in FIG. Then, each knitted loop is heat-sealed and fixed in the same manner as described above, and the unblocking process is reliably performed. Furthermore, for example, as shown in FIG. 12, the polyurethane elastic fibers 50 that form a part of the knitting loops 26 and 25 are formed so that the knitting loops 26 and 25 face the knitting loops 27 and 28, respectively. The knitted loops 25, 26, 27, 28, and 29 are formed by bringing the facing knitted loops together with the crossing points of the knitted loops and the facing knitted loops by heat fusing with each other. , Each of them is firmly fixed to each other and becomes harder to unravel.

  Further, as described above, the knitting loops are brought into face-to-face contact with each other and thermally fused, so that the convex shape due to the curl peculiar to the flat stitch can be flattened and the thickness of the knitting end edge knitting portion 18 can be reduced. Such a convex knitting end edge knitting portion brings about the poor feeling of touch and is difficult to unravel because the amount of seizure during wearing is reduced.

  A third application example is shown in FIG. 10, FIG. 13 and FIG. The knitting loops 30 and 31 are additionally knitted following the knitting loops 25, 26, 27, 28 and 29 in the application example 2. The knitting loops 30 and 31 are formed by knitting one covering yarn or two covering yarns, which are the same or different, by plating knitting. For example, polyurethane elastic fiber 20 denier with respect to nylon fiber 50 denier. Covered yarn, FTY of nylon fiber 50 denier and polyurethane elastic fiber 18 denier can be used. By knitting the knitting loops 30 and 31, in addition to the effect of the above application example 2, the knitting end edge knitting portion becomes denser due to the increased degree of stitches, and the final end that is most easily unraveled is curled by its elasticity. Then, it can be made harder to understand by entering inside.

  In addition to the pants, the garment having an opening has an underwear such as a pants or girdle having a foot or a waist, a shirt having a hem, a collar and a cuff, or a sock or a waist having a mouth. It can be applied to stockings, cylindrical belly wraps, and the like.
