Document Type and Number:
WIPO Patent Application WO/2022/085166
Kind Code:
A1
Abstract:
A penetration hole (9) penetrating a fastener tape (21, 31), in which a tape ground fabric (25) is coated with a waterproof layer (26), is formed at a constant pitch along a lateral edge part (23, 33) of the fastener tape (21, 31). On one side or both sides of the fastener tape (21, 31), the lateral edge part (23, 33) of the fastener tape (21, 31) is subjected to plasma treatment or corona treatment to form an activating region on a surface of the waterproof layer (26). A fastener element (29, 39) is injection molded to be attached to the lateral edge part (23, 33) of the fastener tape (21, 31). A molten resin that turns into the fastener element (29, 39) after curing adheres to the activating region and fills in the penetration hole (9).
