摘要:
A molded plastic hook fastener product for use in hook-and-loop fastening systems, said product comprising:
a base (35); a multiplicity of hook elements (34c,34c') integrally molded with and rising from said base (35), said hook elements being arranged in rows extending lengthwise along a surface of said base and each of said hook elements defining a footprint on said surface where each said hook element joins said base; and a multiplicity of rip-stops (36a,36b,36c) integrally molded with and rising from said base, said rip-stops being arranged in rows extending lengthwise along said surface of said base and each of said rip-stops (36a,36b,36c) defining a footprint on said surface where each said rip-stop joins said base (35), said rows of rip-stops being interspersed among said rows of hook elements; at least many of said rip-stops (36a,36b,36c) being offset in the lengthwise direction relative to hook elements (34c,34c') in widthwise adjacent rows such that a substantial lengthwise portion of the footprints of the respective offset rip-stops and adjacent hook elements do not overlap lengthwise.

A fastening tape has a sheet-form base carrying an array of hooking members (10, 22, 24, 34) each having a height (h) of about 0.008 inch (0.2 millimeter) or less, as measured from the base, and fiber-engaging features, such as re-entrant tips (18, 32), disposed less than about 0.003 inch (0.08 millimeter) from their upper surfaces, as measured normal to the base. Such hooking members are employed to releasably engage directly into foams and fine denier non-woven materials, such as those of insulation, filters, construction moisture barriers, disposable gowns and diapers.

A distinctive article can include an elastomerically stretchable side panel having a longitudinal dimension and a lateral dimension. A member of hook material is operable connected to a first, laterally outboard edge portion of the side panel, and each member of hook material includes a hook base layer which has an appointed fastening region and an appointed grip region. The fastening region has a plurality of hook elements which are integrally formed with the base layer and extend away from a base plane of the hook base layer. The hook elements are configured to operably engage a selected, co-operating loop material. The grip region has a relatively lower density of the hook elements per unit area, as compared to the fastening region. The fastening region is interposed between the side panel and the grip region. The grip region provides a laterally terminal edge of the article.

摘要:
Medium members such as thread are provided between woven fabric sheet such as warp knitting serving as the other sheet and base member, forming linear raised portions in the woven fabric sheet. The density of woven fabric sheet at the inclined portions to either side of these raised portions becomes coarse and the gaps between fine filaments on the woven fabric sheet spread, so that retaining heads of one sheet can easily enter and so that the fine filaments easily become hooked to the base portion of the retaining heads. Consequently, the retaining of the one sheet and the other sheet in strengthened. and the peeling strength is improved.
摘要:
An enhanced flexibility fastener product (30) has a base (35) and hook elements (34a, 34b, 34c) integrally molded with and extending from the base (35). Hump-shaped formations (36a, 36b, 36c) (referred to as 'rip stops'), that are integrally molded with base (35), are offset relative to the hook elements to reduce widthwise stiffness of the fastener product (30). The edge margins (31) of the fastener (30) are feathered in that they taper or otherwise reduce in thickness over an extended distance, preferably from at or near the hooks (34a, 34b, 34c) to the edge, resulting in a softer, less irritating fastener tape (30). Fasteners products according to the invention are particularly advantageous on disposable absorbent garments (10) such as diapers, sanitary napkins, and other articles of wear which come into contact with the user's skin.
