An improved season cracking resistance of a metallic fastener member is provided and includes a copper alloy containing zinc as a base material. The metallic fastener member includes, as a base material, a copper alloy containing zinc, and the metallic fastener member has a surface to which a rust prevention treatment has been applied and has such a property that, when analyzed by a scanning X-ray photoelectron spectroscopy apparatus, a maximum value of an atomic concentration of Mn is detected at a depth of 100 nm or less from the surface.

A hook and loop fastener includes a first strip having one of loops or hooks and a second strip having another of the loops or the hooks. The first strip has a first longitudinal track orthogonal to the first strip. The second strip has a second longitudinal track, orthogonal to the first longitudinal track. A slider is provided that has an interface disrupting member extends outwardly. A gripping element is provided for manually moving the slider along the first longitudinal track and the second longitudinal track in a first direction and a second direction. Movement of the slider in the first direction brings the first strip into engagement with the second strip. Movement of the slider in the second direction draws the interface disrupting member through the interface between the first strip and the second strip, thereby separating the first strip and the second strip.

A reusable zipper system for allowing a zipper to be installed and removed onto different objects interchangeably. The reusable zipper system generally includes an inner member and an outer member. The inner member is removably secured to an object via adhesive around an opening to be fitted with the present invention. The outer member is removably secured over the inner member. After cutting a slit through the inner member, a zipper assembly which includes zipper tracks and a zipper head may be used to selectively open or close the flaps. When desired, the inner and outer members may be removed from the object to be used elsewhere.

A slider body of a slider includes a slider main member and a slider sub-member. The slider main member includes at least a portion of a first blade and at least a portion of a second blade which are connected to each other through a guide column. The slider sub-member includes a pair of first flange sections and is assembled with and fixed to the slider main member. The slider can easily be attached to a fastener chain. Since the slider stably has a predetermined distance between the first and second blades, it is possible to secure satisfactory sliding properties and operability of the slider.

This fabric fastener tape for a slide fastener is provided with an element mounting section and a tape main body section. The tape main body section is provided with a mesh section. The mesh section has a mesh structure having a framework formed by sets of warp yarns and weft yarns, and the mesh structure has openings formed among the sets of warp yarns and weft yarns. In the mesh section, the weave density of the outermost warp yarn and the outermost weft yarn of each of the sets of warp yarns and weft yarns is higher than the weave density of the warp and weft yarns which are on the inner side of the outermost warp and weft yarns. In the mesh structure of this fastener tape, mesh displacement can be prevented without thermally bonding the crossover points between the warp and weft yarns.

The slide fastener attachment method includes: integrating, by welding or bonding, a fastener chain to which a segmented slider has not been attached and a fastener receiving member, and attaching the slider to the fastener chain after the integration. Thus, welding work operation efficiency is improved, and reduction of production cost can be expected.

A slide fastener chain includes a first tape and a second tape. A row of coupling elements is fixed along an inner edge of the first tape. A row of coupling elements is fixed along an inner edge of the second tape. The coupling elements of the first and second tapes being arranged such that the coupling elements of the first tape interdigitate with coupling elements of the second tape so as to secure the first and second tapes together. The chain includes a bottom stop. At least one of the tapes is provided with an extension portion which extends beyond a bottom stop portion of the tape. A width of the extension portion is less than a width of a portion of the tape which does not form part of the extension portion.
