Embodiment 1

[0060] Cotton 60 / 1 was used as the veil, and MobilonR (22dtex: bare yarn) was used as the heat-fused polyurethane elastic fiber, and a circular knitting machine (28 gauge) was used to plate and knit to produce a jersey. This jersey fabric is subjected to dyeing processing in a normal process, and then to molding processing. Table 1 shows the details of the fibers used and the evaluation results of the molding process.

[0061] In the table, Mobilon R is a registered trademark of Nisshinbo Textile Co., Ltd., ROICA is a registered trademark of Asahi Kasei Fiber Co., Ltd., and ESPA is a registered trademark of Toyobo Co., Ltd. In addition, Bare means bare polyurethane elastic fiber, SCY means single covered yarn, PP means polypropylene, and PU means polyurethane elastic fiber.

Embodiment 2～6

[0063] Using the fibers shown in Table 1, processing was carried out in the same manner as in Example 1. In addition, the structure of the heat fusion polyurethane elastic fiber (SCY) used in Example 2 is as follows.

[0064] Core: heat-fused polyurethane elastane (Mobilon R), sheath: nylon (13dtex)

[0065] Draw ratio: 2.3 times, twist number: 600T / m

[0066] When making blanks, SCY weaves at equal magnification

[0067] Table 1 shows the details of the fibers used and the evaluation results of the molding process. In addition, Examples 2 to 6 are examples in which the fineness of the thermally fused polyurethane elastic fibers and / or the type of non-elastic fibers used in combination were changed and implemented.

Abstract

A woven and knitted fabric according to an embodiment of the present invention includes a yarn containing elastic fibers and at least one kind of non-elastic fibers. The woven and knitted fabric is subjected to mold processing. The elastic fibers contain heat-fusible polyurethane elastic filaments each having a fineness of 17 dtex or more, and at least part of the heat-fusible polyurethane elastic filaments is heat-fused in the woven and knitted fabric. The woven and knitted fabric is subjected to the mold processing at 120 to 190 DEG C.

Description

technical field [0001] The present invention relates to a molded woven product. In particular, the present invention relates to a woven product imparted with good molding processability by using thermally fused polyurethane elastic fibers. Background technique [0002] Attempts to impart moldability to woven or knitted fabrics by blending thermoplastic fibers are known. JP-A-2001-98446 (Patent Document 1) discloses a technique of molding using polyurethane elastic fibers having a high heat setting rate. JP-A-2006-225817 (Patent Document 2) discloses a technique of molding polyurethane elastic fibers and nylon fibers. [0003] However, neither technique can be said to have sufficient molding processability. Moreover, according to such a technique, since the molding process is performed with excessive heat, the thermoplastic fibers of the face yarn (face yarn) are hardened, and as a result, the obtained woven or knitted fabrics sometimes have poor hand feeling and may have ...
