The hook surface fastener (A) has hook fastener elements made of monofilaments on a surface of a base fabric. The loop surface fastener (B) has loop fastener elements made of multifilaments and capable of engaging with the hook fastener elements on a surface of a base fabric. The mixed surface fastener (C) has hook fastener elements made of monofilaments and loop fastener elements made of multifilaments on the same surface of a base fabric. The monofilaments are made from a polyethylene terephthalate-based polyester resin, and the multifilaments are made of a polybutylene terephthalate-based polyester resin.

Abstract: Disclosed is a surface fastener with a plurality of male engaging elements installed on the surface of a plastic substrate. Specifically disclosed is a molded surface fastener wherein the male engaging elements have a stem that rises from the plastic substrate and protrusions for engaging that protrude from the stem to the side. The ratio (D/H) between the height (H) of the engaging elements from the substrate and the length (D) from the peak of the engaging elements to the lower end section of the protrusions is 0.35-0.75 and the rate of substrate coverage by the engaging elements is 25%-45%. The disclosed male molded surface fastener is an improvement on surface fasteners, particularly male molded surface fasteners, that engage when simply overlapped which makes positioning extremely difficult. The disclosed male molded surface fastener almost never engages when positioning and has a high engaging force after final fastening.

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.

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.

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.

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.

Abstract: A tape-shaped engaging member F for fixing an upholstery material to seats, which includes a hook surface fastener composed of a double Raschel-knitted base fabric 1 and projecting mushroom-type fastening elements 2 on the surface of the base fabric and a foamed resin layer 3 integrally united to the back surface of the hook surface fastener, and a method of producing a resin molded article equipped with the engaging member. The tape-shaped engaging member is easily set to a mold, has good in-plane flexibility and deforms in good conformity with three-dimensionally curved surfaces.

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.
