    摘要： Forming a fastener component having heads constructed to engage loops formed e.g. of fibers of a mating component, comprises forming, from a thermoformable material, a preform product having a sheet-form base and an array of preform stems integrally molded with and extending from the base to corresponding terminal ends, by a process having a machine direction and a cross-machine direction. Each molded stem has at least two terminal features spaced from one another in the cross-machine direction, the features having a transverse shape about which engaging fibers can bend, the features having a thickness of about 0.25 mm (0.010 inch) or less, preferably about 0.20 mm (0.008 inch), and for personal care products and the like preferably about 0.1 mm (0.004 inch) or less. The terminal ends of the features are heated to a predetermined softening temperature and the terminal ends are contacted to reform the terminal ends to form heads therefrom that overhang the sheet-form base sufficiently to engage loops.Also shown are molded stems that have at least two terminal features spaced from one another in the machine direction; molded preform having substantially parallel side surfaces on all sides, e.g., of “M” or crossed “M” profile of substantially thin fin or crossed thin fin form of molded stems that carry upwardly directed, spaced apart prongs.Preforms are shown having at least three prongs along at least one coordinate. Each prong of a group of at least two neighboring prongs is coalesced to form a head or all prongs of a stem are coalesced to form a single head.

    摘要： A sheet-form loop product includes a flexible paper substrate and a layer of staple fibers disposed on a first side of the substrate, exposed loops of the fibers extending from holes through the substrate to a second side of the substrate, with bases of the loops being anchored on the first side of the substrate. The loops can be fastening loops. The product is formed by needling the fibers through the paper and then bonding the fibers. Examples include loop fastener materials, towels, abrasive scrubbing pads and sanding materials.

    摘要： Methods of making a sheet-form loop product are provided. One method includes placing a layer of staple fibers against a first side of a substrate comprising a nonwoven web; needling fibers of the layer through the substrate by penetrating the substrate with needles that drag portions of the fibers through the substrate, leaving exposed loops of the fibers extending from a second side of the substrate; and anchoring fibers forming the loops by fusing the fibers to each other and to filaments of the nonwoven web on the first side of the substrate, while substantially preventing fusion of the fibers on the second side of the substrate. Sheet-form loop products are also provided, including for example a flexible nonwoven substrate and a layer of staple fibers disposed on a first side of the substrate, exposed loops of the fibers extending from a second side of the substrate, with bases of the loops being anchored on the first side of the substrate, wherein the fibers on the first side of the substrate are fused together to a relatively greater extent than the fibers on the second side of the substrate.
