摘要： A method of making a touch fastener (10, 11, 50) includes coextruding, side­by-side, a plurality of lanes of polymeric material to form a sheet-form base (12). The sheet-sheet form base (12) includes a lane (14) of a first polymeric material disposed between two lanes (16) of a second polymeric material, the second polymeric material is different from the first polymeric material. The method further includes molding a plurality of discrete fastener element stems (212) extending outwardly from and integral with the sheet-form base (12) in each of the two lanes (16) of the second polymeric material and forming engageable heads (18, 214) on the stems (212).

摘要： A method of manufacturing a composite fastener material (102, 140), the composite fastener material, and products (300, 430, 500) derived from the composite fastener material. The method includes providing two longitudinally continuous sheets (108, 110) of material (104, 106), positioning the two sheets to form a longitudinal, continuous interface (120) between the two sheets, joining the two sheets by introducing one or more molten plastic resins (124) in at least one lane (122, 146), one lane of the resin extending across the interface (120) under conditions that cause the resin to bond to the two sheets (108, 110), molding an array of stems (132) from at least one lane of the resin, the stems extending from an exposed surface of the composite material, and forming engageable heads on the stems to form fastener elements (132), wherein the two sheets differ from one another by one of material composition, thickness, texture, stretchability, breathability, and compressability.

摘要： A bi-stable hook component (20) of a touch fastener can bend into, and remain in, a stable concave position. Another stable position enables initial engagement with a mating component (e.g., a loop component 22). The concave position applies engagement-enhancing tension to the engaged loops (28), and in some cases forces end portions (38) of the hooks (24) into close proximity with one another to secure the fastening and to produce a curved touch fastener that, as engaged, can better conform to an underlying curved surface, such as the contour of a wearer's body. Absorbent articles are provided with such a bi-stable fastening system (48).

摘要： Touch fasteners with different portions having different material properties, and methods and apparatus for making such a product. In one embodiment, the fastener includes a cross-linkable polymer, and a first portion of the fastener is cross-linked and a second portion of the fastener is not cross-linked or is cross-linked to a degree less than said first portion. In another embodiment, the fastener is made in a continuous process on a rotating mold roll (40) having a plurality of fastener element mold cavities (42) extending into the mold roll (40) from its outer circumferential surface. The method includes applying a first polymer to the mold roll (40) and forcing some of the first polymer into the mold cavities (42), with some of the first polymer remaining on the surface of the mold roll (40) in the form of a film having thickness; with a doctoring blade (44), removing at least some of the first polymer remaining on the surface of the mold roll (40) to at least reduce the thickness of the film of the first polymer on the mold roll (40) surface (in some cases, substantially all of the polymer on the mold roll surface is removed); and applying a second polymer to the mold roll (40), the second polymer being compatible with, and adhering to, the first polymer.

摘要： A skin-friendly hook component (20, 86, 94) of a hook and loop fastener that reduces or eliminates the occurrence of red-marking and/or irradiation if brought into contact with a wearer's skin. In one embodiment, the hook component can have a relatively large top surface area among the hooks (24) with respect to a surface area of the hook backing (26). In another embodiment, the hook backing (26) is highly flexible, attributable to a flexible resin and/or modified topography. In yet another embodiment, a highly flexible polymer, or polymers, can be used to make individual hooks (24) such that the hooks bend in response to a minimum amount of pressure. Various illustrated hook tapes have features (74, 78, 88, 98) along their edges to enhance skin-friendliness. A skin-friendly hook component results any combination of the disclosed embodiments. The hook component is particularly beneficial when used in absorbent articles.
