Abstract
Loop materials are provided for touch fastening. Some loop materials include a flexible sheet-form substrate, and hook-engageable fibers secured individually and directly to the substrate, the fibers being disposed in discrete fastening regions of the substrate, leaving fiber-free substrate between adjacent fastening regions. Methods of making and using such loop materials are also provided.
