Elements are made of a polyacetal resin, which can effectively improve the chain crosswise strength while maintaining wear resistance. Provided is a fastener element made of a polyacetal resin composition containing 5 to 30% by mass of reinforcing fibers each having an average fiber diameter of 5 to 15 μm and a numeric average fiber length of 150 to 500 μm.

A magnetic closure system includes first and second opposing bodies with permanent magnets disposed on or in sloping surfaces of the bodies to keep the bodies in contact until being pulled apart. The bodies may be rigid, semi-rigid or flexible strips or elongated structures comprised of separate blocks, each block having two divergent sloping surfaces. Whether in strip or block form, each body may be adapted for attachment to a flexible material or fabric, such that the opposing bodies form a magnetic zipper. The magnetic closure system many be used in conjunction with many products, including clothing, curtains, bags, backpacks, purses, mats, tiles, or any other situation wherein materials or fabrics are joined.

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.

A water-proof fastener tape of an environment-conscious type fabricated using a reduced amount of an organic solvent is provided. The fastener tape includes a base fabric and a water-stop film laminated to at least one surface of the base fabric, the water-stop film includes a surface layer of a polyurethane film and an adhesive layer of a cured product of an aqueous polyurethane adhesive adjacent to the surface layer so that the fastener tape has a laminate structure.

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.

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.

Elements are made of a polyacetal resin, which can effectively improve the chain crosswise strength while maintaining wear resistance. Provided is a fastener element made of a polyacetal resin composition containing 5 to 30% by mass of reinforcing fibers each having an average fiber diameter of 5 to 15 m and a numeric average fiber length of 150 to 500 m.

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.

Provided is an injection molded element for a slide fastener which retains a high degree of practical strength, which does not cause undulation of a fastener tape after attachment thereto, and which has superior moldability. The present invention is an injection molded element for a slide fastener having as a material a polyamide resin composition containing a polyamide resin having a glass transition temperature from 40 to 70 C., the composition having a melt flow rate from 5 to 40 g/10 min, and containing from 40 to 60 parts by mass of the reinforcing fibers per 100 parts by mass in total of the polyamide resin and reinforcing fibers.
