Abstract
A reinforcing tape for a slide fastener and a slide fastener having a pair of fastener tapes whose end portions are reinforced with the reinforcing tapes are disclosed. On the end portion of a fastener tape to which a pin-and-box separator of a slide fastener is fitted, a transparent film layer formed of a thermoplastic elastomer or a thermoplastic resin and a fiber reinforcement layer formed of either a reticular sheet of monofilaments or a thin-layer non-woven fabric of fibers manufactured from a thermoplastic resin of the same type as the transparent film layer are superposed through the medium of an adhesive layer, with the transparent film layer constituting itself a surface layer.

A reinforcing tape for attachment to a fastener tape of a slide fastener comprising (a) fiber reinforcement layer formed of either (a-1) a reticular sheet of thermoplastic resin monofilaments or (a-2) a thin-layer non-woven fabric of thermoplastic resin fibers and (b) at least one transparent film layer made of a thermoplastic elastomer or thermoplastic resin and adapted to be superposed on at least one surface of said fiber reinforcement layer, said fiber reinforcement layer (a) and said transparent film layer (b) being made of the same type of thermoplastic resin, said reticular sheet (a-1) being formed of thermoplastic resin monofilaments of a diameter in the range of 50 to 120 .mu.m and having a density in the range of 20 to 70 monofilaments/cm in each of longitudinal and lateral directions, said thin-layer non-woven fabric having a thickness in the range of 50 to 120 .mu.m.
A slide fastener comprising a pair of fastener tapes each having an end portion reinforced with a reinforcing tape, said reinforcing tape comprising at least one transparent film layer made of a thermoplastic elastomer or thermoplastic resin and a fiber reinforcement layer formed of either a reticular sheet of monofilaments or a thin-layer non-woven fabric of fibers manufactured from a thermoplastic resin of the same type as the transparent film layer and being secured to the end portion of the fastener tape through the medium of an adhesive layer in such a manner that the transparent film layer constitutes itself a surface layer, said reticular sheet being formed of thermoplastic resin monofilaments of a diameter in the range of 50 to 120 .mu.m and having a density in the range of 20 to 70 monofilaments/cm in each of longitudinal and lateral directions, said thin-layer non-woven fabric having a thickness in the range of 50 to 120 .mu.m.
A reinforcing tape for attachment to a fastener tape of a slide fastener comprising a fiber reinforcement layer formed of either a reticular sheet of thermoplastic resin monofilaments or a thin-layer non-woven fabric of thermoplastic resin fibers and at least one transparent film layer made of a thermoplastic elastomer or thermoplastic resin and adapted to be superposed on at least one surface of said fiber reinforcement layer, said fiber reinforcement layer and said transparent film layer being made of the same type of thermoplastic resin, said fiber reinforcement layer being superposed on one surface of said transparent film layer;
- and
- an adhesive layer superposed on said fiber reinforcement layer, said adhesive layer adapted to attach said reinforcing tape to the fastener tape of the slide fastener.
A reinforcing tape for attachment to a fastener tape of a slide fastener comprising a fiber reinforcement layer formed of either a reticular sheet of thermoplastic resin monofilaments or a thin-layer non-woven fabric of thermoplastic resin fibers and at least one transparent film layer made of a thermoplastic elastomer or thermoplastic resin and adapted to be superposed on at least one surface of said fiber reinforcement layer, said fiber reinforcement layer and said transparent film layer being made of the same type of thermoplastic resin, said fiber reinforcement layer being positioned within said transparent film layer and between opposite outer surfaces of said transparent film layer;
- and
- an adhesive layer being superposed on one side of said transparent film layer, said adhesive layer adapted to attach said reinforcing tape to the fastener tape of the slide fastener.
