Zipper manufacturing method and zipper

Abstract

The invention provides a manufacturing method of a zipper and the zipper, and the manufacturing method of the zipper comprises the following steps: S1, processing a cloth belt, weaving the cloth belt by using dark-color original lines, and arranging a side edge part on one side of the cloth belt in the width direction of the cloth belt; S2, machining a tooth chain belt; S3, fixing the tooth chain belt to the side edge part of the cloth belt, and obtaining a to-be-machined product; and S4, printing and dyeing the to-be-processed product, wherein the printing and dyeing color is different from the color of the cloth belt. The cloth belt is formed by weaving the dark-color original lines, so that the cloth belt has the same color as the original lines and is also in a dark color, the color of the cloth belt is not greatly influenced by printing and dyeing dyes in the subsequent printing and dyeing process, and meanwhile, the tooth chain belt is printed and dyed into an expected color. Therefore, the finished products of the cloth belts and the tooth chain belts with different colors can be manufactured, compared with the prior art, the manufacturing process is greatly simplified, waste parts do not exist, and then the manufacturing cost of the zipper is greatly reduced.

Description

technical field [0001] The invention relates to a method for manufacturing a slide fastener. [0002] The present invention also relates to a slide fastener produced by the above slide fastener manufacturing method. Background technique [0003] A zipper is a connecting piece that relies on a continuous arrangement of zipper teeth to realize the merging or separation of items. It is widely used in clothing, bags, tents and other items. And with the development of human social economy and science and technology, the material, structure and performance of zippers have undergone a long evolution process. In the direction of development, small zippers play an increasingly important role in people's lives, showing its importance and vitality more and more. [0004] According to the material of the zipper, zippers are mainly divided into three categories: metal zippers, resin zippers and nylon zippers; among them, the zipper teeth of the metal zipper are discharged through the t...
