Incorporated slide fastener

Abstract

The invention relates to an incorporated slide fastener (110) that is incorporated simultaneously with the weaving of the fastener tape (130) for a zigzag-type continuous element chain (121). The weft yarns (135) of the fastener tape (130) are woven with a single yarn traversing and doubling back in the tape width direction, forming a two yarn set, through the same openings created between the warp threads (133, 134, 136). The fastener elements (120) formed from a synthetic resin monofilament have: engaging heads (122) that engage with the opposing continuous element chain (121); first and second legs (123, 124) that each extend on the first surface and the second surface of the fastener tape in the direction of tape width from the engaging heads (122) and pinch the edge of the tape therebetween; first connecting parts (125) that connect, parallel to the tape surface, first legs (123) that are adjacent in the longitudinal direction of the tape; and second connecting parts (126) that connect, parallel to the tape surface, second legs (124, 124) that are adjacent in the longitudinal direction of the tape. Of the two yarns (135-1, 135-2) configuring the weft yarn (135), one yarn (135-2) is woven diagonally straddling the first surface of a first leg (123) and the second surface of a second leg (124) of adjacent fastener elements (120).

Description

technical field [0001] The invention relates to a weaving zipper, which is formed by weaving a zigzag zipper tooth row into one side edge of the zipper tape while weaving it into a zipper tape. The monofilament made of synthetic resin is molded into a zigzag shape, and the center of the width direction of this zigzag fastener element row was folded in half along the longitudinal direction. Background technique [0002] A technique for producing a slide fastener is known in which continuous fastener elements obtained by molding a synthetic resin monofilament are woven along one side edge of the tape and fixed along with weaving the fastener tape. Typical examples of the fastener elements woven at this time include coil-shaped continuous fastener elements and zigzag continuous fastener elements. These continuous zipper teeth have an engaging head engaging with the teeth of the facing fastener stringer, a connecting portion connecting adjacent teeth, and a pair of upper and lo...

AI Technical Summary

Problems solved by technology

However, for a conventional general slide fastener in which zigzag continuous fastener teeth are woven into the fastener tape while weaving, the weft thread is sometimes woven from the outside across the connecting portion connecting adjacent teeth. In some cases, the weft thread is likely to be cut due to the sliding contact between the inner surface of the slider and the above-mentioned weft thread, and it cannot withstand long-term use.
