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.
Claims27
A loop material for touch fastening, the loop material comprising:
- a flexible sheet-form substrate;
- and
- hook-engageable staple fibers needled through the substrate only in discrete fastening regions of the substrate, to form loops extending from a front side of the substrate in the discrete fastening regions,
- areas of the front side and an opposite back side of the substrate being free of staple fibers between adjacent discrete fastening regions;
- the staple fibers being secured to the back side of the substrate to anchor the loops.

A loop material for touch fastening, the loop material comprising:
- a flexible sheet-form substrate;
- and
- hook-engageable staple fibers needled through the substrate and secured to a back side of the substrate,
- wherein the fibers are secured to the back side of the substrate only in discrete fastening regions of the substrate, leaving areas of the back side and an opposite front side of the substrate free of staple fibers between adjacent discrete fastening regions.

A loop material for touch fastening, the loop material comprising:
- a flexible sheet-form substrate;
- discrete, spaced apart regions of male fastener elements extending from a first surface of the substrate;
- and
- staple fibers needled through the substrate from a back surface of the substrate to form hook-engageable loops extending from the first surface of the substrate and secured to the back surface of the substrate,
- wherein the fibers are secured to the substrate only in discrete loop bearing regions of the substrate, leaving areas of the first and back surfaces of the substrate free of staple fibers between adjacent discrete loop bearing regions.
