  • Patent number: 8399086
    Abstract: A mold-in fastening member which is composed of a strip of substrate, engaging elements formed on one surface of the substrate, and an elastomer layer completely surrounding the engaging elements, the substrate having slits or notches which extend from a widthwise central portion of the substrate to a widthwise end portion of the substrate. The mold-in fastening member bends in conformity with a two- or three-dimensionally complicated shape of a molded article. The mold-in fastening member prevents the surface having the engaging elements from being covered with a foamable liquid molding resin during a mold-in process, thereby preventing the engaging elements from losing the engaging function.

  • Patent number: 8381370
    Abstract: Provided is a fusion-bondable surface fastener which includes a surface fastener and a fusion-bondable film partly fixed to the surface fastener. The surface fastener includes a base fabric made of a knitted or woven fabric and has fastening elements outwardly extending from base fabric, where the base fabric has a first region, a second region and a third region each of which have fastening elements. In the first region, the fastening elements are overlaid with the fusion-bondable film and the fusion-bondable film is fusion-bonded to the surface fastener. In the second region the fastening elements are overlaid with the fusion-bondable film and the fusion-bondable film is not fusion-bonded to the surface fastener In the third region the fastening elements are not overlaid with the fusion-bondable film. The first region and the second region form a fusion-bondable area.

  • Patent number: 8263204
    Abstract: A hook surface fastener excellent in the heat resistance, flame resistance, retention of hook shape, and pull-out resistance of hook engaging elements (fibers). The hook surface fastener is composed of a base fabric and the hook engaging elements formed on the base fabric. The base fabric is a woven fabric composed of warp yarns, weft yarns and fibers constituting the hook engaging elements. The warp yarns and the fibers constituting the hook engaging elements are polyphenylene sulfide fibers. The weft yarns are substantially non-twisted, paralleled yarns of polyphenylene sulfide fibers and heat-fusible fibers having a melting point or softening point each being 230° C. or lower. The polyphenylene sulfide fibers constituting the hook engaging elements have a crystal orientation of 85.0 to 90.0% and a crystallinity of 32.0 to 42.0% so that the retention of hook shape is good. The fibers constituting the hook engaging elements are anchored to the base fabric by fusion of the heat-fusible fibers.

  • Publication number: 20120133194
    Abstract: An engaging member for attaching an upholstery material to a cushion member, which has a positioning member at least one lengthwise terminal end. The positioning member places the starting end of loop engaging element portion in precise position in the groove of the cushion member. The engaging member is long and flexible and bends in conformity with the complicated shape of the curved groove. The method of producing an upholstered cushion molding using the engaging member improves the working efficiency.

  • Publication number: 20110290395
    Abstract: A pneumatic tire with a surface fastener having engagement elements that are prevented from being crushed during curing, and a method of producing such a pneumatic tire. Uncured rubber is filled between the engagement elements of the surface fastener to form a protective rubber layer in which the engagement elements are buried. Then, the surface fastener having the protective rubber layer is placed on an uncured tire so that the surface opposite the surface having the engagement elements is in intimate contact with the inner surface of the tire, and after that the uncured tire having the surface fastener is cured by a curing machine equipped with a bladder.

  • Patent number: 8039083
    Abstract: A fabric separable fastener member is provided which comprises a fiber for a base fabric and a fiber for a fastening element firmly anchored by the fused fiber for the base fabric and which is excellent in flexibility and durability without a back-coated layer. The separable fastener member comprises (?1) a ground warp, (?2) a ground weft containing a binder fiber, and (?3) a pile yarn, and the pile yarn (?3) is anchored by the fused binder fiber. In the separable fastener member, each of the ground warp (?1), the ground weft (?2) and the pile yarn (?3) comprises a polyester fiber, the mass ratio of the ground warp (a1) relative to the ground weft (a2) is 40/60 to 80/20, and the mass ratio of the total amount of the ground warp (a1) and the ground weft (a2) relative to the pile yarn (a3) is 90/10 to 50/50.
