Embodiment 1～4 and comparative example 1～4

[0155] As a core component, "Hytrel" (registered trademark) 6347 (melting point: 215° C.) manufactured by Toray Dupont, which is a thermoplastic polyester elastomer, was used as a core component, and “Hytrel” (registered trademark) 4056 (melting point: 153° C.) was used as a sheath component. After each pellet was dried, it was melted with a separate extruder, and each was metered by a gear pump and flowed into a composite module, and supplied to the extruder to obtain a 700dtex product with a mass ratio of core: sheath = 70:30. Monofilament elastic yarn. The bending rigidity of this elastic yarn was 1.0 cN, and it was used as a weft yarn.

[0156] In addition, 10 167dtex-48 filament yarns of a cationic dyeable polyester yarn (LOCII manufactured by Toray Co., Ltd.) were spun. The obtained filament yarn with a total fineness of 1670 dtex-480 was twisted so that the warp twist coefficient was shown in Table 1, and the obtained yarn was used as the warp. Adjust the warp yarn te...

[0160] As a thermoplastic polyester-based elastomer, Toray Dupont "Hitorel" (registered trademark) 6347 (melting point: 215° C.) was prepared as a core component. In addition, "HITREL" (registered trademark) 4056 (melting point: 153° C.) was prepared as a sheath component. After drying each pellet, melt it with a separate extruder, meter it with a gear pump, flow it into a composite module, and supply it to the extruder to obtain a 400dtex product with a mass ratio of core: sheath = 70:30. Monofilament elastic yarn. The bending rigidity of this elastic yarn was 0.3 cN, and this elastic yarn was used as a weft.

[0161] Five 167dtex-48 filament yarns of cationic dyeable polyester yarn (LOCII manufactured by Toray) were spun. The obtained filament yarn of 835 dtex-240 in total fineness was twisted so that the warp twist coefficient became 2890, and the obtained yarn was used as a warp. Adjust the warp yarn tension and other weaving conditions, make the plain weave fabric reco...

Embodiment 6～8 and comparative example 5、6

[0164] Pellets of "HITREL" (registered trademark) 6347 (melting point: 215° C.) manufactured by Toray Dupont, which is a thermoplastic polyester elastomer, were dried. Then, it was melted by an extruder, metered by a gear pump, flowed into a composite module, and supplied to an extruder to obtain a monofilament elastic yarn of 700 dtex. This elastic yarn is used as a weft. In addition, as a warp, 10 167dtex-48 filament yarns of a cationic dyeable polyester yarn (LOCII manufactured by Toray Co., Ltd.) were spun. The resulting filaments of 1670 dtex-480 in total fineness were twisted so that the warp twist coefficients are shown in Table 1. Weaving conditions such as warp tension were adjusted to produce plain weave fabrics shown in Table 1. The obtained fabric was heat-treated at a temperature of 180° C. for 1 minute by using a pin tenter to make the in-and-out widths uniform, and the overfeed rate in the warp direction was 0%. Then, dyeing processing was carried out accordi...

Abstract

The object of the present invention is to provide a woven fabric which is less prone to mesh dislocation due to friction, has excellent abrasion resistance, has a smooth surface, and is excellent in touch. The present invention is that at least a part of any one of the warp or weft is a fiber (M) that is a monofilament (1), and the fiber (N) intersecting with the above-mentioned fiber (M) is at least a part of a multifilament (2). Fiber (N), and satisfy the following (1) or (2) of the fabric. (1) The above-mentioned monofilament (1) is fused with the above-mentioned multifilament (2), and the following (A) and (B) are satisfied at the same time. 1.0≤a / L≤1.5(A)0.5≤h / b≤1.0(B)(2) The above-mentioned monofilament (1) is not fused with the above-mentioned multifilament (2), and simultaneously satisfy the following (C), (D ). 1.0≤a / L≤1.5(C)0.7≤h / b≤1.0(D)a: the length of the fabric in the cross-section of the multifilament (2) b: the fabric in the cross-section of the multifilament (2) Length L in the thickness direction: distance h between the centers of adjacent multifilaments (2) with fibers (M) interposed therebetween: crimp height of monofilaments (1).

Description

technical field [0001] This invention relates to fabrics. More specifically, it relates to a fabric having excellent abrasion resistance and skin feel that can be preferably used for shoes, work clothes, bags, and the like. Background technique [0002] Conventionally, various fabrics have been proposed in which monofilaments are used for at least a part of either the warp or weft, and multifilaments are used for at least a part of fibers intersecting fibers including the monofilaments. For example, Patent Document 1 discloses a network in which polypropylene multifilaments are used as warp yarns and core-sheath composite polypropylene monofilaments are used as weft yarns. This is obtained by making the melting temperature of the sheath of the core-sheath type composite polypropylene monofilament higher than the melting temperature of the core, and heating the polypropylene after weaving to melt the polypropylene of the sheath to adhere the warp and weft.
