摘要： Loop materials include a flexible sheet-form substrate (14) and hook-engageable fibers (12) secured individually and directly to the substrate, the fibers being disposed in discrete fastening regions (118) of the substrate, leaving fiber-free substrate (120) between adjacent fastening regions. Methods of making and using such loop materials are also provided.

摘要： Methods for forming loop fastener products, including applying heat and pressure to a carded web (10) in a manner which fuses fibers (12) of the web to a substrate (14), thereby forming a bonded web, and then embossing the bonded web to raise discrete regions (58) of the web, each raised region containing hook-engageable fiber portions that are exposed for engagement.

摘要： A method of making a sheet-form loop-engageable fastener product includes placing a layer of staple fibers on a first side of a substrate, needling fibers of the layer through the substrate to form loops extending from a second side of the substrate, removing end regions from at least some of the loops to form stems, and forming loop-engageable heads at free ends of at least some of the stems.

摘要： A method of making a sheet-form loop product can include placing a layer of staple fibers on a first side of a substrate, the layer of staple fibers including first staple fibers and second staple fibers that are intermingled with one another, where a diameter of the smallest circle capable of circumscribing one of the second staple fibers is greater than a diameter of the smallest circle capable of circumscribing one of the first staple fibers; needling substantially only the first fibers of the layer through the substrate by penetrating the substrate with needles that drag portions of the first fibers through the substrate during needling, leaving exposed loops of the first fibers extending from a second side of the substrate; and anchoring the loops of the first fibers by fusing the second fibers to each other on the first side of the substrate.

摘要： Methods of forming a loop product are provided. Some methods include (a) introducing a sheet-form substrate (14) and a layer of polymeric fibers (12) into a needle loom (18), with the fibers disposed on a first surface of the substrate, and (b) needling the fibers through the substrate to form hook-engageable loop structures (48) of the fibers extending from a second surface of the substrate through holes (38) formed in the substrate by the needling. Needling the fibers includes piercing the substrate with a plurality of needles (34) while advancing the substrate in a machine direction at a predetermined speed, while cyclically advancing the needles in the machine direction, during piercing of the substrate, in a manner that causes the needles to travel in a substantially elliptical path, such that while the needles extend through the substrate the needles are moving in the machine direction.
