Method for soaking water-proof zipper in waterproof material

Abstract

The present invention relates to a method for manufacturing penetrated water-proofing material for water-proof zipper. Said method includes the following steps: combining upper die and lower die, injecting PU adhesive into die cavity of upper die, making the zipper be passed through lower portion of die cavity so as to make the PU adhesive be penetrated into the tape cloth of zipper, and utilizing lower edge of upper die to form a doctor blade portion, when the zipper tape is conveyed, using said doctor blade to scrape off excessive liquid PU adhesive and make it be formed into a layer of film on said zipper tape so as to obtain the zipper with water-proofing function.

Description

technical field [0001] The invention relates to a method for making a waterproof zipper infiltrating waterproof material, which can make the general zipper tape penetrate into the cloth webbing tissue due to the impermeable rubber material on the belt cloth, so as to have a highly waterproof function and is suitable for processing. Manufacture of waterproof zipper tape and related similar waterproof cloth. Background technique [0002] Press, the known method of making waterproof zippers, such as U.S. Patent No. 6,105,214, is to attach the waterproof film to the surface of the zipper tape by sticking or hot pressing, because the zipper is a pair of zippers facing each other Composed of cloth tape, it can be linked or separated when the zipper head moves, so when the aforementioned waterproof film is attached to the cloth tape by sticking or hot pressing, another processing procedure must be used to cut the waterproof film to achieve It can be separated, so its manufacturing...

[0002] Press, the known method of making waterproof zippers, such as U.S. Patent No. 6,105,214, is to attach the waterproof film to the surface of the zipper tape by sticking or hot pressing, because the zipper is a pair of zippers facing each other Composed of cloth tape, it can be linked or separated when the zipper head moves, so when the aforementioned waterproof film is attached to the cloth tape by sticking or hot pressing, another processing procedure must be used to cut the waterproof film to achieve Can be separated, so its manufacturing and processing procedures are more complicated, relatively slower processing speed, and higher manufacturing cost

[0003] And because the waterproof film of the traditional waterproof zipper can only be attached to the surface of the zipper tape, it cannot be tightly integrated with the zipper tape. After repeated friction on the surface of the cloth, it is easy to cause the separation of the waterproof film and the zipper tape , resulting in a reduction in the waterproof effect in use
