Abstract

The invention belongs to the field of zippers, and discloses a waterproof zipper and a manufacturing method thereof. The waterproof zipper comprises a pair of zipper belts, zipper tooth rows are arranged on the inner side faces of the two zipper belts respectively, the two zipper tooth rows can be meshed with each other, the inner side faces of the zipper belts comprise first areas and second areas, and the first areas and the second areas are arranged on the two sides of sewing lines of the zipper belts and the zipper tooth rows respectively. The two first areas are located between the two second areas. The waterproof zipper further comprises a first waterproof layer, wherein the opposite sides of the two zipper belts are each provided with a first waterproof layer; a second waterproof layer, wherein the first areas of the two zipper tapes are respectively provided with a second waterproof layer; and a waterproof block which is arranged between every two meshed zipper teeth of the two zipper tooth rows. When the waterproof zipper is soaked in water for a long time or the middle seam of the waterproof zipper expands under the action of transverse tension, the waterproof zipper still has a good waterproof effect.

Description

technical field [0001] The invention relates to the field of zippers, in particular to a waterproof zipper and a manufacturing method thereof. Background technique [0002] A zipper generally includes a pair of zipper tapes, a row of fastener elements disposed on the zipper tape, and a slider for pulling together / opening the two rows of fastener elements. The outer surface of the zipper tape (the side not provided with the chain element row) is laminated with a first waterproof layer with a waterproof function, such as a polyurethane film layer. Core wires are threaded through the two chain element rows. The surface of the core wire is wrapped with the second waterproof layer to form a waterproof core wire. Under the combined action of the first waterproof layer and the waterproof core thread, the zipper has a waterproof function. The first waterproof layer is used to block most of the external water. A small amount of external water enters between the occlusal gaps of t...
