Woven structure of belt form and method for production thereof

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 tape-shaped fabric structure that is soft, hard to twist, and excellent in productivity. Background technique [0002] Belt-shaped fabric structures with a predetermined width corresponding to the purpose are conventionally used as belts attached to clothing or bags, or medical traction belts, back pain belts, seat belts, and conveyor belts. body. Such a tape-shaped fabric structure is also required to have a certain strength and flexibility depending on its use, and to have characteristics that do not twist in the width direction. In addition, when used as a web for a seat belt, comfort during wearing, ease of storage and removal from the tensioner, and the like are particularly required. [0003] Therefore, in order to meet these demands, especially with regard to the tape for a seat belt, many proposals have been made. For example, it has been proposed that, as the weft yarn constituting the tape for a seat belt...

AI Technical Summary

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.
