Manufacturing process for a waterproof zipper tape, and waterproof zipper tape

摘要

A method of making a waterproof zipper tape comprises the steps of: forming a viscous waterproof layer (72) on a separable substrate (71); Attaching the viscous waterproof layer (72) formed on the separable substrate (71) to a base fabric (210) of a zipperstring be and removing the releasable substrate (71) from the viscous waterproof layer (72) attached to the backing fabric (210) of the zipperstring be Promoting the curing of the viscous waterproof layer (72) formed on the base fabric (210) of the zipperstring belt to form a waterproofing layer (72) having a reduced viscosity; and after promoting the curing of the viscous waterproof layer (72), covering the exposed surface of the waterproof layer (72) formed on the base fabric (210) of the slide fastener tape with a reduced viscosity with a separable cover (73).
