Abstract

The invention discloses a high-strength injection-molded zipper. The high-strength injection-molded zipper comprises a zipper cloth belt, zipper teeth, a zipper tooth head, an upper zipper stopper anda lower zipper stopper; the zipper teeth are crossly and uniformly fixed on the zipper cloth belt in an injection molding manner; the upper zipper stopper is arranged at the uppermost part of the zipper teeth; the lower zipper stopper is arranged at the bottommost part of the zipper teeth; the zipper tooth head is arranged on the zipper teeth, can be pulled up and down on the zipper teeth, and meanwhile, can correspondingly enable the zipper teeth to be engaged or separated; in addition, a reinforced through hole is formed in the zipper cloth belt; the zipper cloth belt is formed by weaving natural fibers; and the natural fibers are subjected to special surface treatment before being woven. The injection-molded zipper is simple in overall structure, convenient to produce and manufacture,high in strength, stable in use quality and high in market competitiveness and popularization and application value.

Description

technical field

[0001] The invention belongs to the technical field of zipper processing, and in particular relates to a high-strength injection molded zipper. Background technique

[0002] The cloth tape used in traditional injection molding zippers has a thicker center line on the edge. During zipper production, the hot-melted injection molding material is injected into the zipper mold, and it is located on both sides of the cloth tape in the mold. After cooling, it clamps the thicker center of the cloth tape edge. Thread, forming the combination of chain teeth and cloth belt. Since the fastener elements are made of plastic materials, such a combination makes the bonding strength between the injection molded zipper fastener elements and the cloth tape weak all the time. In particular, injection-molded zippers are mostly used in down garments. In cold seasons and especially low-temperature occasions, the plastic material may be brittle at low temperature, so that the injec...
