Abstract
The present invention is directed at a hook mechanical fastener/fibrous composite comprising hook elements on hook containing backing elements or a netting embedded in a fibrous web. The hook elements preferably are on backing elements that are connected or integral and can be strands oriented at angles to each other in a net form. The backing elements generally have a first outer face and a second outer face. The backing elements on at least one of the first or second outer faces have a plurality of hook elements. The hook containing backing elements are embedded within a fibrous web, preferably by hydroentangling the fibers around the backing element, preferably without use of auxiliary attachment means such as adhesives or point bonding.
