Abstract
Lightweight, non-woven loop products for hook-and-loop fastening are disclosed, as are methods for making them and end products employing them. The products are non-woven webs of entangled fibers of substantial tenacity, the fibers forming both a sheet-form web body and hook-engageable, free-standing loops extending from the web body. The product is stretched and stabilized to produce spaced-apart loop clusters extending from a very thin web of taut fibers. In some embodiments, the fibers include low denier fibers and/or bicomponent fibers.
