Abstract
The invention provides a fastener stringer for a hidden slide fastener. Each of the fastener tapes includes a main tape body, a folded tape portion which is folded into a U-shape, and an element attaching portion. The folded tape portion includes at least two multiple-weave portions in which warp yarn forms a multiple-weave structure, and a single-weave portion arranged at least at one location of an intermediate portion of the folded tape portion. According to this, it is possible to enhance rigidity of the folded tape portion in a lateral direction of a tape, and to prevent a position of the warp yarn from being misaligned at the multiple-weave portion. Therefore, hiding performance of the hidden slide fastener can be enhanced.
Claims26
A fastener stringer for a hidden slide fastener, comprising:
- a pair of left and right woven fastener tapes having a front tape surface and a back tape surface, and continuous fastener elements attached to the left and right fastener tapes, in which
- each of the left and right fastener tapes includes a main tape body, a folded tape portion which extends from one side edge of the main tape body in a lateral direction of a tape and which is folded into a U-shape, and an element attaching portion which further extends from the folded tape portion and to which the fastener element is attached,
- the fastener element includes a coupling head, upper and lower legs extending from the coupling head, and a connecting portion which connects between the fastener elements which are adjacent to each other, wherein
- the folded tape portion includes at least two multiple-weave portions comprising a multiple-weave structure in which two or more layers of weave portions formed of warp yarn and weft yarn are laminated on each other from the front tape surface to the back tape surface, and
- a single-weave portion arranged in at least one location of an intermediate portion of the folded tape portion in which warp yarn and weft yarn forms a single-weave structure.
