Abstract
In a waterproof slide fastener, fastener elements are formed using a synthetic resin which contains a silicone resin or a fluorine-based resin, and a water repellant agent is applied to waterproof tapes and the fastener elements and hence, the waterproof slide fastener can exhibit a water-repellent effect brought about by the waterproof tapes and a water-repellent effect brought about by the fastener elements. Accordingly, it is possible to properly prevent the intrusion of a liquid through a gap formed between the left and right fastener elements and a gap formed between the fastener element and the waterproof tape.
Claims4
A waterproof slide fastener including:
- a pair of fastener stringers where a plurality of synthetic-resin-made fastener elements are attached to opposing tape edge portions of left and right waterproof tapes having a synthetic-resin-made waterproof layer on at least one of first and second tape surfaces;
- and a slider which is attached to element rows each of which is formed of the plurality of fastener elements, wherein each of the left and right fastener elements has an engaging portion which engages with the fastener element of an engaging counterpart, projects from a tape edge of the waterproof tape and is brought into contact with the tape edge portion of the engaging counterpart at the time of engaging of the element rows wherein
- a silicone resin or a fluorine-based resin is contained in the fastener element, and
- a water repellant agent is applied to the waterproof tape and the fastener element.
