Problems solved by technology

Chain stitches woven in this way are also easily stretched in the longitudinal direction and therefore do not provide sufficient shape stability for fastening the fastener
Due to the above reasons, it is difficult to achieve a smooth lock between two rows of opposing fasteners

Embodiment Construction

[0025] Some preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. See attached figure 1 , which shows a point diagram of a braided zipper according to a first embodiment of the present invention.

[0026] Woven zippers are knitted on a universal warp knitting machine with a single needle board. This zipper comprises warp-knitted zipper tape 1, and its base structure adopts (1-0 / 1-1 / 1-2 / 1-1 (attached Figure 2B )) type crochet stitches 13, (1-0 / 0-1 (attached Figure 2C )) type chain stitches 16, and zigzag or zigzag padding wefts that pass through the width direction of the zipper tape 1 on each course. The fastener tape 1 has three adjacent warp threads extending along one longitudinal edge portion thereof to form a fastener support area 2 to which a row of continuous helical loop fastener elements 5 are secured. A single synthetic resin monofilament reciprocates transversely across the above-ment...

Abstract

The invention provides a knitting zipper which is provided with a row of continuous spiral fasteners and a connecting chain-typed stitch. The fastener is knitted on a longitudinal edge part of the warp knitting fastener tape in the fastener tape knitting process; the connecting chain-typed stitch 1 and the substrate structure of the fastener tape are knitted together along a supporting area, thus fixing a row of fasteners 5 on a supporting part and leading thereof to have enough structural stability.

Description

technical field [0001] The present invention relates to a woven slide fastener having a row of continuous fasteners woven on one side longitudinal edge portion of the zipper tape when the zipper tape of the zipper is woven. Background technique [0002] A known woven slide fastener disclosed, for example, by Japanese Patent Laid-Open No. 38-11673 comprises a fastener tape woven from chain stitches and padding weft threads, and a row is woven along one side longitudinal edge portion of the fastener tape. Fastenings made of nylon monofilament. The nylon monofilament passes transversely through the above-mentioned longitudinal edge portion of the fastener tape and forms a row of fastener elements which are continuously woven in the chain stitch during the weaving of the fastener tape. U.S. Patent No. 5035125 discloses another kind of known woven zipper, and it comprises the zipper tape that is woven by chain stitch and a backing weft, along the longitudinal edge portion of one...
