An injection-molded zipper cloth tape and a manufacturing method thereof

Abstract

The invention discloses an injection-molded zipper cloth tape and a manufacturing method thereof. The method comprises the following steps: 1) weaving a common injection-molded zipper blank tape according to a normal process; 2) sewing a wire penetrating the blank tape on the blank tape, and the seam holes of the seam line penetrate the blank belt are correspondingly distributed according to the small holes of the injection moulding chain teeth to be arrange by the zipper cloth tape. 3) finalizing, winding, dyeing and drying the sewn blank tape to obtain the finished cloth tape. The inventionadopts an innovative design concept to form small holes in the cloth tape, and the small holes are not damaged and kept intact in the molding process, so as to ensure the effective high-strength bonding of the injection moulding chain teeth and the quality of the injection moulding chain teeth zipper cloth tape. Moreover, the invention can form one row, two rows or more rows of small holes by simply changing the needle spacing and the needle number of the sewing machine, and realize the effect of simple and variable hole spacing, and can also form the tape small holes with controllable size bydifferent thickness of the sewing machine, the transformation is very flexible, and the practicability and the application value are very prominent.

Description

technical field [0001] The invention relates to the technical field of zipper tape, in particular to an injection molded zipper tape and a manufacturing method thereof. Background technique [0002] The traditional injection molding zipper tape has a thicker centerline on one edge of the tape, and the injection molded chain elements embrace the centerline to form a bonding force. However, this binding force is weak, and the teeth are easily detached from the centerline of the tape during the zipper test. Aiming at this problem, a main solution at present is to provide a small hole inside the center line, and a reinforcement column will be formed in the small hole when the chain element is injected, which can well avoid the problem of the chain element falling off. At present, the holey cloth tape is mainly realized in the following ways: 1, referring to the disclosed "zipper tooth chain and its manufacturing method" of CN200510084983.2, adding water-soluble warp yarns in th...

AI Technical Summary

Problems solved by technology

[0003] The several technical methods mentioned above all form small holes when weaving the ribbon, and then after the subsequent processes of shaping, winding, dyeing, and drying, the small holes formed by the ribbon in the early stage are squeezed out by other yarns, causing the small holes to be incomplete. stable or disappearing problems

Moreover, at present, only small holes with a single fixed and unchangeable pore size and pore distribution form can be formed, which cannot be adapted to different chain types, and the applicability is not good.
