Embodiment Construction

[0026] See also Fig. 1~shown in Fig. 7, it is the preferred embodiment of slide fastener of the present invention and manufacturing method thereof, wherein, the manufacturing method of this slide fastener comprises the following steps:

[0027] a. Provide a zipper 1 with two cloth straps 2 .

[0028] b. Apply a liquid polymer on the surface of the tape 2 of the zipper 1 so that the liquid polymer penetrates into the tape 2 . as well as

[0029] c. The liquid polymer is solidified to form the waterproof layer 3 .

[0030] In step b, the liquid polymer is PVC (polyvinyl chloride) containing plasticizer or polyester solvent, PU (polyurethane) material or silica gel material, and the PU (polyurethane) material can be single liquid or double liquid type. When the liquid polymer is coated on the surface of the zipper 1 tape 2 by screen printing or dripping, the liquid polymer can directly penetrate between the fibers of the cloth tape 2 and solidify at room temperature to form a ...

Abstract

The present invention relates to waterproof zip fastener and its making process. During the making, one kind of liquid polymer is first coated to the surface of two cloth belts, so that the liquid polymer permeates into the cloth belts and form waterproof layer after curing; and one other kind of liquid polymer is then on the first waterproof layer to form the designed waterproof structure.

Description

technical field [0001] The invention relates to a slide fastener and a manufacturing method thereof, in particular to a waterproof slide fastener and a manufacturing method thereof. Background technique [0002] Zippers are widely used in various products such as garments, footwear, leather bags, suitcases or carrying bags. The easy-to-open and seal characteristics of zippers allow people to quickly access various small items more conveniently. . [0003] Please refer to Figure 8, the structure of a general zipper a1 is mainly to combine a group of chains a2 that can engage with each other on the top of a group of cloth belts a3, when the two cloth belts a3 are respectively sewn on garments, footwear, leather bags, etc. When the two sides of the openings of articles such as luggage, suitcase or carrying bag, can make the zipper a1 play the expected function. The structure of the above-mentioned slide fastener a1 is quite simple in use, but when the two chains a2 are meshed...
