Problems solved by technology

This scheme uses relatively special materials, which will increase the corresponding cost (material cost, management cost, etc.), and the water-soluble fiber dissolved during dyeing will affect the dyeing accuracy or add new costs to the wastewater treatment after dyeing, and because the cloth tape The weft yarn still exists in the warp exclusion area, so it is difficult for the injection material to penetrate effectively on both sides of the zipper tape during the production of the injection molded zipper, and the improvement of the bonding force between the elements of the injection molded zipper and the tape is limited.

Embodiment 1

[0045] Depend on figure 2 It can be seen that the injection molded zipper tape 6 of the structure of the present invention includes: the center line 5 of the edge of the tape, a group of warp yarns 3 and continuous weft yarns 2; figure 2 The centerline 5 and some warp yarns such as 31, 32...36, 37 are located in the area of ​​the joint surface between the tape 6 and the fastener element 1, and the rest of the warp yarns 38, 39... are located outside the joint surface. Such as figure 2 As shown, the warp yarns 33 and 35 are set to a structure of one up and one down circulation, and the middle warp yarn 34 is set to a structure of three down and three up cycles; while the warp yarns 36, 38 and 37 are opposite to the warp yarns 33, 35 and 34 , set to a structural organization of one-up-one-up and three-up-three-down cycles. The fabric tape woven under such a structural structure, due to the influence of the warp yarn tension, the interweaving points of the weft yarns 21, 23 ...

Embodiment 2

[0047] As a further improvement of the structural cloth tape of the present invention, another improved setting is made to the warp structure in the area of ​​the joint surface of the cloth tape and the zipper element, and the structural organization of the three warp and weft threads is formed into a small hole, which is improved to The structure of four warp yarns and weft yarn loops forms small holes; image 3 As shown, the warp yarns 32, 35 are set to a structure of one up, two, one, up, two, up, and down cycles, and the middle warp yarns 33, 34 are set to a four-down, four-up cycle structure; and the warp yarns 36, 39 and 37, 38 is opposite to warp yarns 32, 35 and 33, 34, and is set to a structure of one, two, one, one, two, one, four, four, four. The cloth tape woven under the same principle as in Example 1, due to the influence of warp and weft tension, the interweaving points of warp yarns 35, 36 and weft yarns 24, 25 are shifted, and small holes 4 are formed in the m...

Embodiment 3

[0049] As a further improvement of the structural cloth tape of the present invention, the warp yarns in the area of ​​the joint surface of the cloth tape and the zipper elements are thinned. Change it to 167dtex, so that the number of warp yarns in the joint area will increase; as Figure 4 As shown, warp yarns 31, 32...310, 311 are located in the joint surface area, and warp yarns 33, 34, 35, 36, 37, 38, 39, 310, 311 are set according to embodiment 1; The cloth tape that weaves out after fixing forms two rows of small holes between warp yarns 35,36 and 38,39, and two rows all form intervals every three weft yarns evenly, and the size is consistent.

Abstract

The invention discloses a novel injection zipper cloth strap comprising a central line (5) at the edge of the cloth strap, a group of warp (3) and continuous wept (2). Continuous and alternately-arranged small holes (4) are arranged in a joint surface zone of the cloth strap and the injection zipper teeth and formed by setting the structural tissue of the warp of the cloth strap through the mutual influence of tension between the warp and the wept while braiding. The holes in the injection zipper cloth strap are formed without special tools, special procedures or special materials, and the warp and the wept of the cloth strap are kept to be integral with uninfluenced appearance and strength. The invention has the advantages of convenient and simple production and can enhance the binding force between the zipper cloth strap and the zipper teeth, and the like.

Description

technical field [0001] The invention relates to a cloth tape for an injection-molded zipper, in particular, after using the cloth tape, the binding force between the elements of the injection-molded zipper and the zipper tape can be significantly improved. Background technique [0002] The traditional injection molded zipper is composed of cloth tape and chain teeth, such as Figure 7 As shown in the cross-section of the traditional injection molded zipper, the tooth body 12 of the zipper element is located on both sides of the zipper tape 6. At the same time, the tooth body 12 wraps the thicker center line 5 at the edge of the tape. The combination of the element and the tape is mainly It is realized by enclosing the center line 5 of the chain tooth body 12; the combination of the cloth tape and the chain element in such a structure, coupled with the characteristics of the injection molding material of the chain tooth, so relatively speaking, the injection molded zipper chai...
