Problems solved by technology

However, in this method, a special knitting machine with a jacquard mechanism must be used, and fabrics with different weaving patterns must be manufactured according to the style and size of the product, which lacks manufacturing adaptability.
In addition, in this method, since the weave is partially changed, it is easy to produce a thicker cloth
[0006] In addition, in Patent Document 3, although a method of corroding a cloth containing modified polyester fibers, nylon fibers, and elastic fibers is described, it does not describe how to increase the elasticity of the etched part and control the elasticity by using the fibers constituting the cloth. technical solution, these fibers are only used to enhance the design (decorative) effect

Embodiment 1

[0070] As the braided fabric, it was produced by using a compound obtained by copolymerizing 2.25 mol% of a compound having an alkali metal sulfonic acid group (sodium isophthalic acid-5-sulfonate) and 5.0 mol% of adipic acid. Polyethylene terephthalate fiber 33 decitex (dtex) / 12 filament (f) untwisted yarn as corrosive fiber a, and nylon 66 fiber 44dtex / 20f as non-stretchable non-corrosive fiber c The toriskin structure, using polyurethane fiber 44dtex / 1f and polyurethane fiber 156dtex / 1f as stretchable non-corrosive fiber b for the insert yarn, is stretched twice and woven to obtain a raschel knitted fabric. The raschel knitted fabric is heated from low temperature to high temperature to 80°C for open-width scouring, and then fixed to a specified width with a setting temperature of 180°C. The weaving warp is 46 inches, weft is 49 inches, and the fabric unit weight is 260 g / m 2 The basic knitted fabric of the processed cloth.

Embodiment 2

[0092] Except that the warp is 45 inches and the weft is 50 inches, the same as in Example 1, the basic knitted fabric for making the processed cloth, in the position where the middle elasticity needs to be obtained, forms the corroded part of the floret pattern with an area ratio of 50%, in addition, Under the same conditions as in Example 1, etching was performed.

[0093] The elasticity of the obtained Raschel knitted fabric was evaluated by the elongation and the stress at 30% elongation, and the elongation of the non-corroded part was 148% in the warp direction, 74% in the weft direction, and 30% elongation. The stress is 168cN / gf in the warp direction and 347cN / gf in the weft direction; the elongation of the corroded part is 119% in the warp direction and 245% in the weft direction, and the stress at 30% elongation is 80cN / gf in the warp direction , the weft direction is 51cN / gf; in addition, the elongation ratio of the corroded part relative to the non-corroded part is ...

Embodiment 3

[0099]In knitted fabrics, as the corrosive fiber a, the intrinsic viscosity (dissolve the polymer in a mixed solvent of phenol 1:tetrachloroethane 1, measured by Ubbelohde viscometer at 25°C) 0.6, 2mol% melting point 244 ℃ of isophthalic acid-5-sodium sulfonate and 5mol% of adipic acid and polyethylene terephthalate copolymerized polyester polymer as the sheath component, polyethylene terephthalate with intrinsic viscosity 0.72, melting point 256 ℃ Ethylene phthalate is used as the core component, and according to the ratio of core component 1: sheath component 2, the untwisted yarn of the core-sheath composite fiber of 56dtex / 24f obtained by core-sheath composite spinning and drawing at 290°C is used, Except not using the non-corrosive fiber c, it was woven into a triskin structure in the same manner as in Example 1 to obtain a raschel knitted fabric. Same as embodiment 1, this Raschel knitted fabric is scoured and shaped to obtain a weaving warp of 48 inches, a weft of 50 in...

Abstract

A fabric composed of regions different in stretchability which has relatively high-stretch regions and relatively low-stretch regions, wherein the former regions are constituted of stretch fibers and nonstretch fibers and exhibit an extension higher than that of the latter regions; and a process for the production of the fabric which comprises applying an etching paste containing an etching accelerator by printing to arbitrary portions of a stretch base fabric and removing part or the whole of etchable fibers (a) present in the portions with an etching agent and which satisfies the following requirements (1) to (4): (1) the stretch base fabric is constituted of the etchable fibers (a), unetchable fibers (b), and unetchable fibers (c); (2) at least part of the etchable fibers (a) are made of a polymer soluble in the etching agent; (3) the unetchable fibers (b) are insoluble in the etching agent and exhibit stretchability; and (4) the unetchable fibers (c) are insoluble in the etching agent and exhibit nonstretchability.

Description

technical field [0001] The present invention relates to a cloth having partially different elastic properties and a method for producing the same, more particularly, to a method for producing a cloth having partially different elastic properties after post-processing. [0002] This application claims the priority of Japanese Patent Application No. 2005-372767 filed with the Japan Patent Office on December 26, 2005 and Japanese Patent Application No. 2006-243664 filed with the Japan Patent Office on September 8, 2006, and Its contents are cited here. Background technique [0003] Conventionally, in clothing, in order to have a body shape correction function or a muscle support function by partially applying the pressure difference when the clothes are applied, the fabric and woven cloth as the basis are formed with other materials or tissues. elastic part. Patent Document 1 describes a method of overlapping and sewing a wide elastic band-shaped cloth from the inner side of ...
