Woven Zipper Zipper Tether Tape

Abstract

In fastener stringers for knitting slide fastener (10, 20, 30 and 40), element fitting parts (2b and 2b') are provided with a chaining thread (17) woven to a wale (W1) on an outermost side and at least two fixing chaining threads (18). Base chaining threads (15 and 17) forming the wale arranged on a side of element engagement head parts (4a and 4a') in wales (W1 and W4) adjacent to the wales (W2 and W3) to which the fixing chaining threads (18) are knitted are provided with first warp knitting threads (11, 21, 31 and 41) which are confounded in respective courses with needle loops and are woof-inserted into at least one wale (W2 or W3) to which the fixing chaining thread (18) is knitted and is folded. The wale arranged in the side of the element engagement head can securely be reinforced. The wale and the wales (W2 and W3) to which the fixing chaining thread (18) is knitted are brought close and stitch density is improved. A form as knitting is stabilized. Since warp threads are not overlapped between the wales constituting the element fitting part, the element fitting part does not become bulky.

Description

technical field [0001] The present invention relates to a zipper stringer tape for a woven zipper, which is formed on one side edge of the zipper tape by weaving and fixing a continuous zipper string element row while knitting a zipper tape made of a warp-knitted weave. On the chain element installation part. Background technique [0002] In the past, many kinds of fastener stringers for woven slide fasteners have been proposed. In the fastener stringers for knitted zippers, while knitting the fastener tape by warp knitting, the continuous fastener element rows are knit in a chain shape for fixing. The yarn is continuously woven while being fixed to the element attaching portion of the fastener tape. [0003] For example, in the fastener stringer disclosed in Japanese Unexamined Patent Application Publication No. 2006-263315 (Patent Document 1), in order to avoid breakage of the needle during knitting, and to stabilize the fastener element row in terms of dimensions, it is ...

AI Technical Summary

Problems solved by technology

As a result, when the slider is attached to the fastener stringer 51 to manufacture a woven slide fastener, the friction between the element attachment portion 52a and the slider becomes large, so that burrs are likely to be generated on the element attachment portion 52a. question

[0018] In addition, since the friction between the element attaching portion 52a and the slider increases, the positions of the knitting yarns knitted into the element attaching portion 52a tend to shift when the slider is slid.

As a result, there is a problem that the form of the element attaching portion 52a cannot be maintained stably, resulting in a decrease in meshing strength.

[0019] Furthermore, in the fastener stringer 51 of Patent Document 1, in order to reinforce the wale W1 of the first row, it is necessary to increase the amount of knitting yarn used to knit the element attachment portion 52a and to increase the number of knitting machines. yarn guide, so as a result, there is also a problem that leads to an increase in manufacturing cost
