Description

TECHNICAL FIELD

[0001] The utility model relates to zip fastener technical field, especially in a zip fastener, invisible zip fastener and take zip fastener article. BACKGROUND

[0002] Because of the insufficient rigidity of the zip fastener, when the invisible zip fastener is installed on the article such as the car seat, the powerful tension of the seat skin can cause the deformation and everted of the cloth belt bending part of the zip fastener and the exposure of the zipper teeth, so that the left and right zipper teeth are easily separated when the zipper head pulls the zip fastener.

[0003] When the rigidity of the zipper tooth mounting part of the zip fastener is increased, the deformation and everted of the cloth belt bending part and the exposure of the zipper teeth can be solved, but in the process of sewing the zipper teeth to the zipper tooth mounting part, the sewing needle and the sewing thread need to be inserted into the zipper tooth mounting part continuously, and the too large rigidity of the zipper tooth mounting part can easily cause the breakage of the sewing needle or the sewing thread, thereby leading to the failure to realize the continuous normal production. In view of the above problems, the present case is produced after the problem is researched deeply. UTILITY MODEL CONTENTS

[0004] The utility model wants to solve the technical problem, in order to provide a zip fastener, invisible zip fastener and take zip fastener article, can reach the rigidity of zip fastener increase simultaneously, and make the sewing needle or sewing thread not be broken in the process of sewing zipper tooth.

[0005] The utility model is realized as follows:

[0006] Firstly, a zip fastener comprises a zip fastener cloth belt and zipper teeth, the zip fastener cloth belt is sequentially provided with a cloth belt main body part, a cloth belt bending part and a zipper tooth mounting part along the width direction, the zipper tooth mounting part specifically comprises a sewing needle insertion part and a single silk weaving part, the sewing needle insertion part uses yarn as warp, and the single silk weaving part uses single silk as warp, and the zipper teeth are sewn together with the sewing needle insertion part through the sewing thread.

[0007] Further, the sewing needle insertion part uses one-over-one weave.

[0008] Further, the single silk weaving part uses two-over-two weave.

[0009] Further, the cloth belt bending part uses one-over-one weave and two-over-two weave, and the cloth belt main body part uses two-over-two weave.

[0010] Further, the zipper tooth mounting part is provided with at least two sewing needle insertion parts and at least two single silk weaving parts along the width direction of the zip fastener cloth belt, and the sewing needle insertion parts and the single silk weaving parts are alternately arranged.

[0011] Furthermore, the monofilaments woven into the monofilament portion are made of PET monofilaments, and the diameter of the monofilaments is 0.20mm-0.35mm.

[0012] Furthermore, the warp yarns of the main body of the fabric tape, the folded part of the fabric tape, and the sewing needle insertion part are all made of polyester network yarn with a specification of 333-500dtex.

[0013] Furthermore, the weft yarn of the zipper tape is made of polyester yarn with a specification of 500dtex-1000dtex.

[0014] Secondly, an invisible zipper includes two zipper strips as described above and a zipper head that drives the two zipper strips to open and close.

[0015] Thirdly, a zippered item, wherein the zippered item employs the aforementioned concealed zipper.

[0016] By adopting the technical solution of this utility model, at least the following beneficial effects are achieved: The zipper tooth mounting part is specifically designed to include a sewing needle insertion part and a monofilament weaving part. The sewing needle insertion part specifically uses yarn as the warp yarn, and the monofilament weaving part specifically uses monofilament as the warp yarn. The zipper teeth are sewn onto the sewing needle insertion part. Because monofilament has stronger rigidity than yarn, the rigidity of the zipper tooth mounting part can be effectively improved, thereby increasing the overall rigidity of the zipper and ensuring that the zipper will not deform or turn outwards during use, or that the zipper teeth will be exposed. Simultaneously, because the sewing needle insertion part has lower rigidity, it ensures that the sewing needle or thread will not break during the sewing of the zipper teeth, thus enabling continuous and normal production and achieving the effect of increased production and reduced consumption.
