  • Patent number: 6811862
    Abstract: The present invention provides a resin composition for a slide fastener. In one embodiment, upon setting, the resin composition does not melt even upon contact with a hot surface. In addition, the fastener provides low sliding resistance or friction, as well as durability and structural strength to withstand repeated opening and closing operations. Finally, the fastener can be dyed with cloth in the same bath.
