Background

Zippers (zippers), which are connectors for uniting or separating articles by means of a continuous arrangement of zipper teeth, are now widely used in clothing, bags, tents, etc.

The zipper is composed of zipper teeth, a zipper head, an upper stop and a lower stop (a front stop and a rear stop) or a locking piece and the like. The fastener elements are key parts, and directly determine the side pull strength of the zipper. Generally, a zipper has two fastener tapes, each fastener tape has a row of fastener elements, and the two rows of fastener elements are arranged in a staggered manner. The zipper teeth at two sides are clamped by the pull head, and the zipper teeth at two sides can be mutually meshed or separated by sliding the pull tab.

The zipper is divided into three types according to materials, including a nylon zipper, an injection molding zipper and a metal zipper.

The down jacket (down coat) is a jacket filled with down fillers, and has a huge and mellow appearance. The down jacket generally has more than half of the amount of the duck down, and meanwhile, some fine feathers can be mixed, the duck down is cleaned and disinfected at high temperature, and then the down jacket is filled in clothes. The down jacket has the best warmth retention property. It is usually worn by people in cold regions and is also commonly used by polar researchers.

The zipper that adopts on the present down coat is of a lot of varieties, the part that zip fastener and down coat sewed up is the strap in the zip fastener, it is the part that takes place the friction between the easiest and the down coat cloth also, for example, when daily dress down coat, can rub and produce static phenomenon between zip fastener and the down coat surface fabric or with inside clothing between, long-time use then can lead to down coat inside to follow and sew up the clearance department with the zip fastener cloth and bore out because of static and from, lead to the quality of down coat to descend greatly, and can appear frequently in daily use and draw the condition that the zipper head cliies inside surface fabric of down coat or other clothing surface fabrics at the removal in-process, handle improper then very easily can damage or lead to its deformation with drawing the zipper head, thereby influenced the life of whole zip fastener.
