Problems solved by technology

Therefore, there is a problem that if the slider is repeatedly slid, the weft yarn will be cut off from the lower flange and the chain tape will be damaged. Therefore, the slide fastener cannot withstand long-term use.
[0024] In particular, in this case, no matter how much the density of the warp is increased at the part of the belt in contact with the lower flange, the weft may be stretched, and it is difficult to prevent warp misalignment caused by the contact of the slider, and it has not become fundamental. The means to solve the problem of weft yarn being cut

Embodiment 1

[0092] figure 1 is a schematic diagram showing the slide fastener of the present embodiment 1, figure 2 It is a perspective view showing the bag using the zipper. also, image 3 It is a structure diagram which schematically shows the knitting structure of a part of the fastener tape. and, Figure 4 is a cross-sectional view of the zipper.

[0093] In addition, in the following description, the front-back direction means the longitudinal direction of a fastener tape, and is the same direction as the sliding direction of a slider slide. In particular, the direction in which the slider slides so that the left and right zipper elements mesh to close the zipper is defined as the front, and the direction in which the slider slides so that the left and right zipper elements are separated to open the zipper is defined as the rear. .

[0094] In addition, the left-right direction means the width direction of the fastener tape, and is a direction parallel to the tape surface of ...

Embodiment 2

[0143] Figure 11 It is a main part cross-sectional view enlargedly showing the main part of the slide fastener of this Example 2.

[0144] The slide fastener 2 of the present embodiment 2 is constituted as a usual type of slide fastener, and it has a pair of fastener stringers 40 in which spiral fastener elements 51 are sewn along the belt inner edges where the left and right fastener tapes 41 face each other. The unshown first stopper and second stopper at the front end and the rear end of each fastener chain 40 , and the puller disposed so as to be slidable along the continuous element rows of the fastener chain 40 . Head 60.

[0145] Here, in the slide fastener 2 of this Example 2, the fastener element 51 has the structure similar to the conventional spiral fastener element, and the 1st stopper, the 2nd stopper, and the slider 60 have the same structure as a conventional spiral fastener element. The conventional 1st stopper, the 2nd stopper, and the slider used for the s...

Embodiment 3

[0156] Figure 12 It is a sectional view which shows the invisible slide fastener of this Example 3.

[0157] The concealed slide fastener 3 of the third embodiment has a pair of concealed type fastener chains 70, a first stopper and a second stopper (not shown) arranged at the front end and the rear end of each fastener chain 70 , and the slider 90 arranged so as to be slidable along the continuous element row of the fastener chain 70 .

[0158] The concealed type fastener chain 70 of the present embodiment 3 has a chain belt 71 and a continuous chain element row arranged along the chain element mounting portion 71c of the chain belt 71. A belt bending portion 71b extending from one side edge and bent into a letter U shape, and a chain tooth mounting portion 71c further extending from the belt bending portion 71b.

[0159] The continuous element row is formed by sewing the helical zipper element 81 on the fastener tape 71 with a multi-thread chain stitch of sewing thread 87...

Abstract

This slide fastener (1, 2) is configured such that a fastener tape (11, 17, 18, 19, 41) comprises a single-ply woven structure and has a double-ply woven region (13, 13a, 43) formed along the longitudinal direction of the tape, the double-ply woven region (13, 13a, 43) comprising a double-ply woven structure. An inner single-ply woven region (14, 14a, 14b, 44) and an outer single-ply woven region (15, 45), which have a single-ply woven structure, are formed on the tape inner edge side and tape outer edge side of the double-ply woven region (13, 13a, 43). As a result of the configuration, weft yarns (9) arranged in the double-ply woven region (13, 13a, 43) are less likely to be cut even if the fastener tape (11, 17, 18, 19, 41) makes contact with ridge line sections (34c, 64a) on the lower wing plate side of a slider (30, 60) when the slider (30, 60) is slid, and consequently the lifetime of the slide fastener (1, 2) is extended.

Description

technical field [0001] The present invention relates to a slide fastener and a concealed slide fastener, and particularly to a slide fastener and a concealed slide fastener configured so that the weft yarn of a fastener tape woven by a slider is not easily cut by a slider even if the slider is repeatedly slid. Background technique [0002] Conventionally, in order to smoothly open or close an opening of a bag or the like, a slide fastener is attached to the opening, and the slide fastener is opened or closed by sliding a slider along the element row in a separating direction or a meshing direction of the element row. [0003] In such slide fasteners, in general, in order to perform smooth opening and closing operations, it is desired to improve the slidability or operability of the slider, and to prevent other members from being caught in the tape penetration gap of the slider when the slider is slid. [0004] In addition, in slide fasteners, problems such as friction betwee...
