Description

      The present invention relates to a fabric for clothing.

      In general, fabrics frequently used for clothing and the like are woven fabrics and knitted fabrics, and are manufactured by weaving or knitting using yarns manufactured from fibers or the like as raw materials. Each property is made of warp and weft yarns that are crossed up and down according to certain rules, so there is almost no elasticity in the direction of the fabric, and a little stretch in the other directions. There is sex. On the other hand, a knitted fabric is one or one or more yarns that make a loop, and continue to make the next new loop by hooking on that loop. It has elasticity in any direction of 360 °. In addition, the cloth used for clothing as described above is a flat surface as it is, and a three-dimensional unevenness is formed by performing a processing process such as stitching, and a cloth product such as clothing is manufactured. ing. These are disclosed in Non-Patent Document 1.

Further, overlock stitching (edge stitching) may be applied to the fabric as described above at the end of the fabric end (stitch) to prevent unraveling. This overlock stitching (edge stitching) forms an overlock stitch structure with the needle thread 1, the upper looper thread 2, and the lower looper thread 3 in the case of an overlock sewing machine with one needle and three threads (see FIG. 1). . Unlike the lockstitch sewing machine, the overlock sewing machine cannot perform reverse stitching and it is not necessary. Therefore, the overlock sewing machine performs the idle stitching operation and cuts the thread leaving the thread foot. That is, even if there is no object to be subjected to overlock stitching (edge stitching), the overlock stitch structure is continuously formed if the idle stitching operation is continued. These are disclosed in Patent Document 1.

If overlock stitching (edge stitching) is applied to the fabric edge of a stretchable fabric such as a knitted fabric to prevent unraveling, the fabric edge may be stretched and wavy or shrunk too much. In that case, move the differential lever of the overlock sewing machine up and down to perform a sewing test, and adjust the differential lever to the best position. When the differential lever is lowered, the feed amount is increased and the cloth end is in the contracting direction, and when the lever is raised, the feed amount is decreased and the extending direction is reached. In other words, by adjusting the differential feed to the fabric edge of the non-stretchable fabric and applying overlock stitching (edge stitching), the fabric edge can be shrunk or stretched and wavy. . These are disclosed in Non-Patent Document 2.
JP-A-5-156539 Edited by Osamu Yumi, “Clothing Materials and Arrangement”, Asakura Shoten, April 20, 1980, P38-49 Kumasaki Takamichi, “Apparel Sewing Glossary” Channeler, September 9, 2002, P138-139

In order to form a three-dimensional unevenness on a conventional cloth for clothing, a process such as stitching has to be performed. Further, there is no conventional cloth for clothing or the like that is not stretchable only in one direction and stretchable in other directions. The present invention has been made to solve these problems.

The invention of claim 1 for solving this problem is formed of a needle thread 1, an upper looper thread 2 and a lower looper thread 3 which are obtained by causing a single stitch three thread overlock sewing machine to perform a blank stitching operation. Overlock stitching (edge stitching) is applied to the overlock stitch structure (see FIG. 1), and each overlock stitch structure is entangled (see FIG. 2). In this state, overlock stitching (edge stitching) is continued to produce a fabric.

The upper looper thread 2 is hooked on the needle thread 1 and the lower looper thread 3 to form a loop, and the lower looper thread 3 is hooked on the needle thread 1 and the upper looper thread 2 to form a loop, whereas the needle thread 1 Is moving up and down so as to cross the upper looper yarn 2 and the lower looper yarn 3, and no loop is formed. That is, the upper looper yarn 2 and the lower looper yarn 3 form a structure similar to a knitted fabric, and the needle yarn 1 forms a structure similar to a warp or weft yarn of a fabric. Therefore, the upper looper yarn 2 and the lower looper yarn 3 have the same properties as the knitted fabric, and therefore have elasticity in any direction of 360 °, and the needle yarn 1 has the same properties as the warp yarn or weft yarn of the fabric. There is almost no sex. Therefore, the overlock seam structure (see FIG. 1) has almost no stretchability only in one direction where overlock stitching (edge stitching) is applied, and has stretchability in the other directions. Because this fabric is manufactured by continuing overlock stitching (edge stitching) to this structure, there is almost no elasticity only in one direction where overlock stitching (edge stitching) is applied, and stretch in the other direction. There is sex.

      According to a second aspect of the present invention, the three-dimensional unevenness is formed in the fabric of the first aspect by adjusting the differential feed of the overlock sewing machine when performing overlock sewing (edge stitching). When forming a concave fabric, lower the differential lever of the overlock sewing machine and perform overlock stitching (edge stitching) with the feed amount increased to shrink the fabric edge. If the overlock stitching (edge stitching) is further applied to the contracted fabric end, the fabric end can be further contracted. By repeating this process, a concave fabric is gradually formed.

      When forming a convex fabric, raise the differential lever of the overlock sewing machine and perform overlock stitching (edge stitching) with the feed amount reduced to extend the fabric end. If the overlock stitching (edge stitching) is further applied to the stretched fabric end, the fabric end can be further stretched. By repeating this process, a convex fabric is gradually formed. By combining the operation for forming the concave fabric and the operation for forming the convex fabric, three-dimensional unevenness is formed on the fabric.

Since there is no elasticity only in the direction where overlock stitching (edge stitching) is applied, when used as clothing, if the direction where overlock stitching (edge stitching) is applied becomes the vertical direction, It is possible to produce clothing that is stable in shape and easy for the wearer to move when worn.

Since the fabric has three-dimensional unevenness, it is not necessary to perform a processing step such as stitching when manufacturing a three-dimensional fabric product such as clothing.

Overlock stitching (see Fig. 1) overlock stitch structure (see Fig. 1) formed from needle thread 1, upper looper thread 2 and lower looper thread 3 made by performing an empty stitching operation on an overlock sewing machine with one needle and three threads Edge over stitches) are entangled with each overlock stitch structure (see FIG. 2). Further overlock stitching (edge stitching) is continued in this state, and a differential feed is adjusted to form a fabric structure with three-dimensional unevenness.

      When overlock stitching (edge stitching) is applied to an overlock stitch structure (see Fig. 1) formed by performing an empty stitch operation on the overlock sewing machine, the needle thread 1, upper looper thread 2 and lower looper thread 3 are cut. If the overlock stitching (edge stitching) is continuously performed from the end of the thread that has started the idle stitching operation, a tubular fabric structure can be formed. In addition, a cylindrical fabric structure with three-dimensional unevenness can be formed by adjusting the differential feed and performing overlock stitching (edge stitching).

Since the fabric according to the present invention is manufactured by an overlock sewing machine, it has industrial applicability.

It is a figure of the overlock seam structure which made the overlock sewing machine of the 1 needle 3 thread used as the origin of the cloth concerning the present invention carry out empty stitch operation. FIG. 2 is a diagram showing a state in which overlock stitching (edge stitching) is applied to the overlock stitch structure of FIG. 1 and each overlock stitch structure is entangled.
