Problems solved by technology

[0010] However, if the yarn has no stretch and is used in a normal zipper tape material, when applied to a zipper tape constructed with a normal weave structure, the main part of the tape has no stretch due to the weave structure
Therefore, once a wrinkle occurs in the zipper tape, the zipper vertical bar cannot correct its wrinkle state to a linear state
Therefore, when the fastener tape is sewn to garments etc., the sewing process becomes complicated
In addition, after sewing, the zipper attached to the garment etc. is not flat in its longitudinal direction, which results in many poor-quality products in a wavy state

Embodiment Construction

[0024] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0025] figure 1 The weaving structure of the fastener tape which is a typical example of the basic structure of this invention is shown. Simultaneously, figure 1 The braided structure shown is only roughly represented for the sake of understanding, in fact, as figure 2 As shown, it is a dense structure.

[0026] Usually, such woven zipper tapes are woven by a narrow weaving machine, which is called a knitting machine. Thus, the individual threads are reciprocated in the gap so that two parallel threads are inserted into a single weft thread 2 . Although in this figure, the two inserted yarns 2a, 2b constituting the weft yarn 2 are separated from each other in the vertical direction, actually, they are in close contact with each other in the vertical direction. Then, the loop end formed at the return end of the weft yarn 2 is wound with the l...

Abstract

A zipper tape (1) having a tape main part (5) obtained by weaving and a component mounting edge part (4) in which core threads (7a, 7b) are braided, for the base warp of the tape main part (5) (6e, 6f...6m, 6n) have a lower coefficient of thermal contraction than the other warp yarns (6a to 6d). The core wires (7a, 7b) have a high coefficient of thermal contraction. The warp yarns (6c, 6d) adjacent to the inside of the core wires (7a, 7b) have a lower coefficient of thermal contraction than that of the core wires (7a, 7b). It is thereby possible to obtain a zipper vertical bar (8) in which, even after the component (E) is mounted, wrinkles do not occur in the component mounting edge portion (4), thus ensuring straightness.

Description

technical field [0001] The invention relates to a zipper tape obtained by weaving. More particularly, it relates to a zipper tape which is unlikely to produce so-called creases which cause the tape to protrude in one plane towards the component mounting side or its opposite side, thereby deforming the tape into an arc, even in the connection of the parts After various heat treatments and installed on the belt. Background technique [0002] A zipper tape is a tape specially used for zippers having a number of engaging or mating parts fixed at regular intervals along the side edge portion of the tape, fitted with sliders and top / bottom end plugs, and manufactured in its Sew to garment or various pockets after required length. [0003] After the zipper tape is woven, it is cut to the required length through a series of steps such as heat setting, dyeing, drying, and component installation. Sliders are placed to pass between opposing parts and connect the top / bottom end plugs...
