Embodiment Construction

[0042] Hereinafter, the embodiments of the waterproof zipper of the present invention and the manufacturing method thereof will be described in detail with reference to the accompanying drawings.

[0043] In the zipper with the waterproof effect of the present invention, the zipper tape 3 is woven or knitted by synthetic resin fibers, such as polyamide fibers and polyethylene fibers, and is composed of a double-layer composite composed of a low-melting resin layer 12 and a high-melting resin layer 13. The resin composite film 4 is fused to one surface of the fastener tape by pressing and heating. Therefore, this zipper has a waterproof function.

[0044] In such figure 1 with figure 2 In the first embodiment of a zipper with a waterproof effect shown, a core thread 7 passes through the inside of a linear loop-shaped element 5 made of synthetic resin monofilament such as polyamide and polyethylene. The leg 15 is sewn on the surface of the side 11 of the zipper tape 3 with a sewing...

Abstract

The present invention intends to provide a waterproof slide fastener in which a synthetic resin film is fused to a fastener tape in order to prevent a perforation phenomenon that the synthetic resin film does not exist locally. A laminated synthetic resin film (4) composed of low melting point resin layer (12) having melting point of, for example, 100 DEG C - 140 DEG C and high melting point resin layer (13) having melting point of, for example, 150 DEG C - 230 DEG C is fused to a surface or both surfaces of a pair of the fastener tapes (3) with the low melting point resin layer (12) being in contact with and opposing the fastener tape (3) by heating with pressure. Fastener elements (5) are mounted onto a side edge (11) of the fastener tape (3) and the laminated synthetic resin film (4) is formed so as to protrude outward from the side edge (11) of the fastener tape (3) and a center point of coupling of the fastener elements (5). Because the high melting point resin layer (13) disposed on the surface of the fastener tape (3) is not melted, no perforation phenomenon occurs. Further, because the laminated synthetic resin film (4) protrudes from the side edge (11), waterproof function is secured.

Description

Technical field [0001] The present invention relates to a waterproof zipper used as an opening / closing device for ski shirts, sports bags, and other similar articles by providing a zipper tape with a waterproof function, and a method of manufacturing such a zipper with a waterproof effect. Background technique [0002] Conventionally, there is known a fastener tape in which a synthetic resin film is fused on the entire surface of a pair of left and right fastener tapes. According to a zipper disclosed in Japanese Utility Model Publication No. 40-17549, for example Figure 19 As shown, the synthetic resin film 4'is stacked and fused to the entire rear surface of the left and right zipper tape pairs 3', and a core 7'is fixed to one side 11' of the zipper tape 3'. Then, all the fastener elements 5'are installed to the core thread fixing part to make a zipper with waterproof effect. [0003] In the currently known zipper, the synthetic resin film is fused on the entire surface of the...
