Curved zipper and manufacturing method thereof

Abstract

The invention discloses an arc-shaped zipper and a manufacturing method thereof. The manufacturing method of the arc-shaped zipper includes the steps of weaving an outer arc cloth tape and an inner arc cloth tape, and implanting the teeth forming side of the inner arc cloth tape during the weaving process. Enter the first high-temperature shrinkage line; the teeth molding, the injection molding of the teeth on the teeth forming side of the outer arc cloth belt and the teeth molding side of the inner arc cloth belt, and the two adjacent teeth on the inner arc cloth belt There is a first high-temperature shrinkage line between the teeth; teeth occlusion, the multiple teeth on the outer arc cloth belt and multiple teeth on the inner arc cloth belt are mutually occluded; high temperature shrinkage, the outer arc after the teeth are occluded The cloth tape and the inner arc cloth tape are placed in a heating device to be heated to a preset temperature and kept for a preset period of time, and the length of the first high-temperature shrinkage line between two adjacent teeth on the inner arc cloth tape shrinks by a first length. The manufacturing method of the arc-shaped zipper can effectively solve the problem of uneven stress on the teeth on the outer-curve cloth tape and the teeth on the inner-curve cloth tape of the arc-shaped zipper.

Description

technical field [0001] The invention relates to the technical field of daily necessities, more specifically, to an arc-shaped zipper and a manufacturing method thereof. Background technique [0002] With the rapid development of clothing design, people have higher and higher requirements for every detail of clothing. In order to show personality, many clothes are designed with curved zippers. The curved zipper in the prior art includes an outer arc cloth belt and an inner arc cloth belt, and a plurality of teeth are arranged on one side of the outer arc cloth belt, and a plurality of teeth are arranged on one side of the inner arc cloth belt, The width of the teeth on the outer arc cloth belt is greater than the width of the teeth on the inner arc cloth belt, so that when the teeth on the outer arc cloth belt and the teeth on the inner arc cloth belt are engaged with each other, the zipper forms an arc-shaped zipper. However, since the width of the teeth on the outer arc c...
