Description

Resin zipper

Technical Field

The utility model relates to a zip fastener field especially relates to a resin zip fastener.

Background

The zipper is a common article in daily life and is mainly applied to articles such as clothes, bags and the like. At present, zippers mainly comprise three types, namely a resin zipper, a metal zipper and a nylon zipper, wherein the manufacturing process of the resin zipper is relatively simple, and the resin zippers in different shapes can be manufactured only by manufacturing related dies. Therefore, in the entire zipper field, the shape of the resin zipper is the most varied and can satisfy different demands.

With the increasing demand of individuation of people, the resin zipper with changeable shape is difficult to meet the individuation requirements of people on clothes and the like, so that a technology of processing the outer surface of the resin zipper facing people again appears, the resin zipper obtains more changes, and the decoration aesthetic property of the resin zipper is improved. Such as: the chinese patent application No. 201810884457.1 discloses a slide fastener in which a transfer foil and a surface (i.e., a non-transfer portion) formed by removing a part of the transfer foil are transferred onto an upper surface (i.e., an outer surface facing a person) of a resin fastener element, so that the upper surface of the fastener element has the transfer foil and the non-transfer portion, thereby obtaining a fastener element having different visual effects, thereby improving the appearance of the resin slide fastener and improving the decorativeness of the resin slide fastener to meet the individualization requirements of the person for clothing and the like. However, the above slide fastener has the following drawbacks:

1. in the manufacturing process of the zipper, the zipper teeth in the zipper are firstly subjected to film pasting treatment and then physically ground to remove a part of the transfer foil, so that the manufacturing process of the zipper is increased, and the production difficulty is increased; in addition, the physical polishing is likely to cause variations, and the transfer foil after polishing is likely to be damaged at the edge where it is in contact with the non-transfer portion.

2. The above-mentioned slide fastener can only physically grind the fastener elements in the longitudinal direction of the slide fastener to form the non-transfer portion, which can only add different visual effects in the longitudinal direction of the slide fastener, but cannot add different visual effects in the width direction of the slide fastener.
