Problems solved by technology

However, due to the high rigidity and poor flexibility of the monofilament, if the monofilament is inserted as a weft yarn, when the monofilament bends at the end of the ear portion of the strip, yarn cutting is likely to occur, so frequent weaving occurs. The problem of production efficiency deterioration due to interruption
In addition, even if the yarn cut does not occur, the monofilament protrudes slightly from the ear end surface of the tape, resulting in a poor wearing feeling when worn as a seat belt.
[0011] In addition, in Patent Document 4, multifilaments having a large single-yarn fineness and multifilaments having a small single-yarn fineness are used for mixed weaving, but it is difficult to carry out the above-mentioned mixed weaving uniformly, and there are problems in that the process is complicated and the productivity is poor.
Therefore, it is considered to reduce the fineness of the single yarn to improve productivity, but the effect of increasing the rigidity in the weft direction becomes insufficient for the multifilament after the fineness of the single yarn is reduced.
In addition, the above-mentioned Patent Document 5 has the problem that the rigidity in the weft direction decreases sharply after long-term use because the thermosetting resin peels off and falls off during the use of the tape.

Embodiment 1

[0089] As the warp yarn, a black polyester multifilament dyed with a stock solution of 1670dtex / 144f, a breaking strength of 8.4cN / dtex and an elongation of 12% is arranged to a warp density of 390 threads / 2.54cm, and as a weft yarn, a sheath component of 280dtex / 16f It is a core sheath of polyethylene terephthalate copolymerized with 25 mol% isophthalic acid (softening point 185°C) and the core component is polyethylene terephthalate (melting point 240°C) with an intrinsic viscosity of 0.68 Type hot-melt polyester yarn (manufactured by Kanebo Kanebo Co., Ltd., Bellcouple [registered trademark], core / sheath ratio = 3 / 2), and 720dtex / 72f (softening point 240°C), breaking strength 6.5cN / dtex, elongation 20% polyester fiber is combined with silk, and the tape is woven with a knitting machine according to a width of 5cm and a weft density of 20 / 2.54cm. Next, the tape is heat-treated at a temperature of 200°C to melt the sheath component, and the surrounding polyester fiber is melt-fix...

Embodiment 2

[0091] As the weft yarn, instead of the core-sheath type hot-melt polyester yarn of Example 1, the total amount of 280dtex / 48f was used copolymerized with 5 mol% isophthalic acid and 5 mol% 2,2-bis[4-(2 -Carboxyethoxy)phenyl]propane copolymer component polyester multifilament (softening point 200°C, limiting viscosity 0.69, maximum heat shrinkage stress 0.23cN / dtex, BWS23%, 130°C dry heat shrinkage rate 21%, 180 ℃ dry heat shrinkage rate 30%), except that it is the same as the above-mentioned Example 1, to obtain the target belt-shaped fabric structure.

Embodiment 3

[0093]In place of the core-sheath hot-melt polyester yarn of Example 1, a 167dtex / 48f sheath component is polyethylene terephthalate (softening point 185°C) copolymerized with 25 mol% isophthalic acid and the core component is used It is a core-sheath type hot-melt polyester yarn of polyethylene terephthalate (softening point 240°C) with an intrinsic viscosity of 0.68 (manufactured by Kanebo Co., Ltd., Bellcouple [registered trademark], core / sheath ratio = 2 / 1 ), except that it was the same as in Example 1 above, and the target belt-shaped fabric structure was obtained.

Abstract

A band-form woven-fabric structure which is formed by weaving from non-fusion-bondable synthetic fibers and fusion-bondable synthetic fibers including in the fiber surface a fusion-bondable ingredient having a softening point lower by at least 30 DEG C than that of the non-fusion-bondable synthetic fibers, wherein the fusion-bondable synthetic fibers are used as at least part of the weft in the woven-fabric structure and have undergone a heat treatment at a temperature not lower than the softening point of the fusion-bondable ingredient, whereby the fusion-bondable synthetic fibers have been fusion-bonded to themselves or to the non-fusion-bondable synthetic fibers. According to this woven-fabric structure, a band-form woven-fabric structure, e.g., a webbing for seat belts, can be efficiently produced which, even when used repeatedly, retains the weft-direction rigidity over long and is less apt to twist and which is soft and easy to handle.

Description

Technical field [0001] The present invention relates to a belt-shaped fabric structure that is soft, hard to be twisted, and excellent in productivity. Background technique [0002] As belt ropes attached to clothing, bags, etc., or medical traction belts, low back pain belts, seat belts, conveyor belts, etc., conventionally used belt-like fabric structures with a predetermined width corresponding to the purpose are used body. For such a belt-shaped fabric structure, it is required to have certain strength and flexibility according to its use, and it is required to have the characteristic of not being twisted in the width direction. In addition, when it is used as a belt for a seat belt, comfort during wearing, ease of storage and removal with respect to a tightener, and the like are particularly required. [0003] Therefore, in order to meet these requirements, especially regarding the belt material for seat belts, many proposals have been proposed. For example, a proposal has b...
