Method for Manufacturing A Watertight Zipper
The present disclosure provides a method for manufacturing a watertight zipper for solving the problem of production difficulties. A method for manufacturing a watertight zipper according to the present disclosure includes: forming a waterproof tape by extruding a polymeric material in melted state wrapping around an outer surface of a cloth tape, cutting a side of the waterproof tape that is covered by the thick waterproof layer by laser to form a side surface of the thick waterproof layer in a plane form as an abutting surface, forming a plurality of apertures at the waterproof tape, wherein each of the plurality of apertures extends through the cloth tape and the thick waterproof layer, and forming a plurality of scoops corresponding to the plurality of apertures by injection molding. The waterproof tape includes a thick waterproof layer and a thin waterproof layer both formed by the polymeric material in solidified state. The thick waterproof layer covers a side surface, an upper surface and a lower surface of the cloth tape. The thin waterproof layer connects with the thick waterproof layer. Each of the plurality of scoops spaces from the thin waterproof layer. An end of each of the plurality of scoops extends beyond the abutting surface of the thick waterproof layer.
Waterproof zipper and process of manufacturing same
A waterproof zipper is provided with two halves, each including a half tape member and a row of protruding teeth along an inner edge of the half tape member; and a waterproof layer is secured to an inner surface of the halves. A process of manufacturing the waterproof zipper is also provided, including the steps of: (a) guiding the waterproof layer to a position above the two halves on a continuous flow production line, each half having a half tape member and a row of protruding teeth along an inner edge of the half tape member; (b) coating a waterproof layer on a releasing layer; (c) drying both the waterproof layer and the releasing layer in an oven.

Waterproof Zipper and Process of Manufacturing Same
A waterproof zipper is provided with two halves, each including a half tape member and a row of protruding teeth along an inner edge of the half tape member; and a waterproof layer is secured to an inner surface of the halves. The waterproof layer coated on the inner surfaces of the halves may prevent the liquid from penetrating into the interior of the waterproof zipper, and simplify the structure of the waterproof zipper. A process of manufacturing the waterproof zipper is also provided.
Waterproof fastener stringer and method of producing the same
Through-holes are formed at a constant pitch along a side-edge portion of a fastener tape where a tape base fabric is covered by a waterproof layer, the through-holes piercing the fastener tape. Plasma treatment or corona treatment is applied to the side-edge portion of the fastener tape so as to form an activation region on a surface of the waterproof layer on one or both sides of the fastener tape. Injection molding of fastener elements is performed to attach the fastener elements to the side-edge portion of the fastener tape. Melted resin adheres to the activation region and fills the through-hole before solidifying into the fastener element.
