Abstract: A slide fastener includes a pair of waterproof stringers comprising a pair of woven and/or knitted fastener tapes, a pair of coil elements respectively secured to opposing side-edge portions of the pair of fastener tapes, and waterproof films respectively overlaid via adhesives on tape top surfaces of the fastener tapes of the pair of fastener tapes, and a slider that moves forward to engage the pair of coil elements and moves rearward to disengage the pair of coil elements. Each of the waterproof films has a film edge positioned over a space between the opposing side-edge portions of the pair of fastener tapes, the film edge supported by a supporting portion made of the adhesive solidified, the supporting portion partially occupying the space between the opposing side-edge portions of the pair of fastener tapes, and the supporting portion having a thickness greater than a thickness of the film edge.

The adhesive penetrates into a structure of the fastener tape such that the waterproof film and the fastener tape are in direct contact at least partially.

Abstract: A method for manufacturing a waterproof fastener tape includes the steps of: forming a viscous waterproof layer on a releasable substrate; attaching the viscous waterproof layer formed on the releasable substrate to a fastener tape base fabric, and peeling the releasable substrate off the viscous waterproof layer that has been attached to the fastener tape base fabric; promoting curing of the viscous waterproof layer formed on the fastener tape base fabric to form a reduced-viscosity waterproof layer; and after the promoting of curing of the viscous waterproof layer, covering an exposed surface of the reduced-viscosity waterproof layer formed on the fastener tape base fabric with a releasable cover.
