Fastener stringer for hidden slide fastener

Abstract

A fastener stringer (1) for a hidden slide fastener is provided with a left and right pair of fastener tapes (10, 40, 50) and fastener elements (20). The fastener tapes (10, 40, 50) are provided with main tape bodies (11), folded tape sections (12) folded in a U shape, and element mounting sections (13). The folded tape sections (12) are each provided with at least two multiple-weave sections (15, 45, 55) in which warp yarns (31) form a multiple-weave structure, and also with a single-weave section (16) provided at at least a portion in an intermediate section of the folded tape section (12). The configuration increases the rigidity of the folded tape sections (12) in the lateral direction of the tapes and prevents the positions of the warp yarns (31) from being displaced in the multiple-weave sections (15, 45, 55) in the lateral direction of the tapes. This causes, even if the fastener stringer (1) is subjected to lateral pulling force, the folded tape sections (12) to be less likely to move in the direction in which the folded tape sections (12) are separated from each other, and as a result, the hidden slide fastener (2) can be more effectively hidden.

Description

technical field [0001] The present invention relates to a fastener stringer for a concealed slide fastener that can be concealed so that the meshed tooth rows are not seen from the outside of the fastener stringer exposed outside the fastener stringer when the left and right tooth rows are meshed. Background technique [0002] In general, a zipper is roughly divided into a normal type zipper in which the engaged left and right dentition is arranged on the tape surface side of the zipper tape and exposed, and a method in which the engaged left and right dentition cannot be seen from the outside. There are two representative types of zippers (so-called invisible zippers) that perform concealment. Concealed zippers are suitable for various clothes, shoes and other products by making good use of the advantage of being concealed without hindering the design of the product. In addition, in recent years, they are also used for seat covers for seats in cars and trains. Wait. [00...

Problems solved by technology

Therefore, it is also considered that, for example, when using sewing thread to sew the fastener element to the element attachment portion, it is difficult for the sewing machine needle to penetrate through the element attachment portion, resulting in breakage of the sewing machine needle, etc.
