Description

  In the present invention, in the underwear and underwear such as shirts and pants, the end edges of the knitted ends such as cuffs and hems formed by bag knitting are processed to release and give a sense of volume and stretch power. Related to clothing.

  FIG. 11 is a schematic perspective view of a pant knitted in a cylindrical shape by a conventional cylindrical forming circular knitting machine with a partial cross section based on the XX cross section in FIG. 72 is a bag knitting portion of the waist portion 7, 75 is a hem portion, 76 is a bag knitting portion of the skirt portion 75, and 77 is a connecting portion provided on the upper end side of the bag knitting portion 72 of the hem portion 75. 78, 80 is a knitting end edge knitting portion and is integrally knitted together with the connecting portion 77, and the knitting end edge knitting portion 80 is knitted on two courses of flat knitting courses 81 and 82. ing. Reference numeral 85 denotes a presser sewing portion in which presser sewing 85 is integrally applied to the flat knitting courses 81 and 82, the bag knitting portion 76, and the body portion 70.

  Since the flat knitting course 82 which is the final end course of the knitting end edge knitting portion 80 is particularly easy to unravel, as described above, the flat knitting course of the knitting end edge knitting portion 80 over the entire circumference of the hem. 81, 82, the bag knitting part 76 and the body part 70 are integrally formed with presser stitches 85 so as to surely prevent the unraveling. However, in the case of the bag knitting portion 72 of the waist portion 71, since the body portion 70 is continuously knitted following the knitting of the bag knitting portion 72, the knitting end edge knitting portion 80 is knitted like the hem 75. Certain flat knitting courses 81 and 82 are not required, and therefore it is not necessary to prevent unraveling.

  The problem to be solved is that, since the presser stitching is integrally performed on the knitting end edge knitting part, the bag knitting part and the body part over the entire circumference of the hem, the part of the presser sewing is convex. And the feeling of wearing due to the presser foot sewing is deteriorated and the feeling of wearing is lowered, and the presser stitching is integrally performed on the knitting end edge knitting portion, the bag knitting portion and the body portion, so that an excessive amount of sewing is required. There is a lack of improvement in quality and efficiency, such as requiring landing work and causing a reduction in production efficiency.

The present invention relates to a garment having openings that are knitted one by one by a cylindrical forming circular knitting machine, wherein the openings are constituted by bag knitting, and heat fusion is performed on the knitting end edge knitting portion of the bag knitting portion. The most important thing is that the heat-sealed yarn and the yarn other than the heat-welded yarn are welded at the intersection of the stitches and unclamped by knitting the yarn and further heat-treating it with wet heat or dry heat. It is a characteristic.

In the present invention, a heat fusion yarn is knitted into the knitting end edge knitting portion of the bag knitting portion, and the heat fusion yarn and a yarn other than the heat fusion yarn are knitted through heat treatment by wet heat or dry heat . By welding at the intersections and applying a release-preventing process, it is no longer necessary to perform presser foot stitching integrally on the knitting end edge knitting part, the bag knitting part and the body part over the entire circumference of the hem as in the conventional case. Therefore, the feeling of touch caused by the convex presser sewing is eliminated and the feeling of wearing is improved, and the conventional useless press stitching is integrally performed on the knitting end edge knitting portion, the bag knitting portion and the body portion. Sewing process is not required, production efficiency is improved, and further, the above-mentioned fusion processing prevents curling at the edge of the fabric, improving the feeling of volume (bulkiness) and stretchable power, etc. Clothing with excellent effects can be obtained.

According to the present invention, in a garment knitted one by one by a cylindrical forming circular knitting machine and having an opening, the opening is constituted by a bag knitting, and the knitting end edge knitting part of the bag knitting part It is characterized in that the heat-sealed yarn is knitted at the part and further heat-treated by wet heat or dry heat to weld the heat-fused yarn and the yarn other than the heat-fused yarn at the intersection of the stitches. Hereinafter, description will be made based on the example of the drawing. 1 is a pant, 2 is a front body, 3 is a back body, 32 is a tubular body fabric, and constitutes a front body 2 and a back body 3, and 5 is a waist formed by a bag knitting portion 6. , 7 is a hem formed by the bag knitting portion 8, 9 is a crotch portion formed by the crotch fabric 10, and 11 and 12 are bag knitting portions provided at both ends of the crotch fabric 10, respectively. .

  In FIG. 3, reference numeral 15 denotes a connecting portion provided at the upper end of the bag knitting portion 8 of the skirt portion 7 through a binding yarn 16, and reference numeral 18 denotes a knitting end edge knitting portion of the bag knitting portion 8. 15, and the knitting end edge knitting portion 18 is knitted with flat knitting courses 20 and 21. As the flat knitting course of the knitting end edge knitting portion 18, several courses may be knitted, but preferably the range of 1-2 courses is optimal. Further, as the yarn usage of the flat knitting courses 20 and 21, knitting is performed by using the aligned yarns of the ground yarn 22 and the heat-fusible yarn 23, and the ground yarn 22 is made of natural fibers such as cotton or natural fibers. An appropriate blended yarn made of synthetic fiber or the like is used, or a synthetic fiber such as polyester fiber is used alone. Further, as the heat-fusible yarn 23, nylon, polyester fiber, polyurethane fiber or the like is used. Used as appropriate.

  Further, as a means for heat-treating the aligned yarn made of the ground yarn 22 and the heat-fusible yarn 23, for example, the knitted fabric after knitting is in the range of 50 ° C to 70 ° C, preferably in the range of 55 ° C to 65 ° C. It is preferable to heat-treat. The heat treatment is preferably wet heat treatment with steam or the like (dyeing or the like) or dry heat treatment such as hot air drying. By heat treating the knitted fabric, the heat-fusible yarn 23 is melted and crosses the stitches. The ground yarn 22 and the heat-fusible yarn 23 are reliably melted and bonded.

  In FIG. 5, 30 is a forming circular knitted fabric for pants 1 knitted one by one by a cylindrical forming circular knitting machine, 32 is a cylindrical body fabric, and constitutes a front body 2 and a back body 3. Further, the upper and lower edges of the formed circular knitted fabric 30 are knitted with the bag knitting portions 6 and 8 of the waist portion 5 and the hem portion 7, respectively. The formed circular knitted fabric 30 is preliminarily heat-treated by wet heat treatment (dyeing or the like) or hot air drying to melt the heat-fusible yarn 23 and heat-melt the base yarn 22 at the intersection of the stitches. It is preferable that the adhesive yarn 23 is reliably melted and bonded. Reference numeral 35 denotes an arc-shaped crotch forming cutting line provided at the lower intermediate portion of the formed circular knit fabric 30. By cutting the fabric 30 along the line 35, the crotch portion 9 as shown in FIG. An arcuate cutting portion 36 is formed.

  In FIG. 7, 38 is a formed circular knitted fabric knitted by a cylindrical forming circular knitting machine in the same manner as described above, and is configured to form the crotch fabric 10 of the pants 1. The bag knitted portions 46, 46, 46... With the same knitting structure as the hem 7 are cutting lines for forming the crotch fabric, and by cutting the formed circular knitted fabric 38 along the line 46. As shown in FIG. 8, a rectangular crotch fabric 10 having bag knitting portions 11 and 12 is formed. Further, the crotch portion 9 is formed by sewing the crotch portion fabric 10 on the side of the arc-shaped cut portion 36 cut in a concave shape at the crotch portion 9 as shown in FIG.

  Apparel having an opening can be applied to underwear and underwear such as shirts and trousers that have cuffs and hems in addition to pants, and can also be applied to cylindrical abdomen.
