Description

Elastic nylon zipper

Technical Field

The utility model relates to the technical field of zippers, in particular to an elastic nylon zipper.

Background

The zipper is mainly matched with cloth in a sewing way and is widely used for various clothes such as clothes, bags and the like; while some elastic cloth (in particular four-side elastic cloth) exists in the existing market, the cloth has elasticity in all directions, and under the action of the elastic pulling action of the cloth, the zipper teeth and the cloth belt of the zipper can be pulled and deformed, so that the appearance shape and the use function of the zipper are seriously affected; in the existing market, although some elastic cloth belt zippers exist, the existing market has certain limitations; firstly, the elastic zipper has the elastic function only on cloth belts, and cloth belt varieties mainly belong to knitting cloth belts, and the cloth belts are seldom woven (woven without a woven belt loom); this is because the knitted fabric tape is liable to cause a difference in tightness in the knitted fabric; however, the knitting cloth belt has loose tissue structure and low physical strength, so that the cloth belt mainly used in the zipper industry is a relatively compact shuttle knitting cloth belt; finally, the element regions of these elastic zippers have no reasonable elastic function in both the warp and weft directions, and the main reason for the limitation of zipper elasticity is: under the existing manufacturing mode, the elastic function in the length direction of the zipper can lead the whole zipper to be under the loosening condition: the cloth belt main body can rebound to shorten, and the sprocket area has no elastic function or has partial elasticity, but the meshing interval of the sprocket can not support the required rebound distance; the zipper teeth area is more than the main cloth belt body in length, and the zipper teeth area is forced to arch to be wavy due to the pulling action of the main cloth belt body; the appearance and related functions of the zipper are severely affected. The nylon zipper, the injection molding zipper and the metal zipper are quite different in the structure of the zipper teeth and the installation mode of the zipper teeth on the cloth belt; the scheme is only developed, implemented and described for the nylon zipper, so that the elastic nylon zipper is arranged to solve the problems.

Chinese utility model patent publication No.: CN215075925U, disclosing: the nylon zipper is smooth, and is not suitable for elastic cloth, the cloth has elasticity in all directions, and under the action of elastic pulling of the cloth, the zipper teeth and the cloth belt of the zipper can be pulled and deformed, so that the appearance shape and the use function of the zipper are seriously affected.
