Abstract:
1. A method of making a sheet-form loop product, the method comprising placing a layer of staple fibers on a first side of a substrate, the layer of staple fibers comprising first staple fibers and second staple fibers that are intermingled with one another, wherein 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.
