Abstract:
1. A method of making a sheet-form hook-engageable loop product, the method comprising placing a layer of staple fibers on a first side of a substrate, the substrate comprising a nonwoven web; needling fibers of the layer through the nonwoven web by penetrating the substrate with needles that drag portions of the fibers through the nonwoven web during needling, leaving exposed loops of the fibers extending from a second side of the substrate; and anchoring fibers forming the loops to the nonwoven web, wherein anchoring the fibers to the nonwoven web comprises laminating the fibers to the nonwoven web by applying heat and pressure to the fibers and the nonwoven web, wherein the layer of staple fibers placed on the nonwoven web has a total fiber weight of less than about 2 ounces per square yard (67 grams per square meter), and the hook-engageable loop product has an overall weight of less than about 5 ounces per square yard (167 grams per square meter), wherein the fibers are loose and unbonded to the nonwoven web and each other until needled.
