Abstract
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.
