Abstract
A touch fastener loop material has a non-woven web of fibers forming both a base and a field of high-tenacity hook-engageable loops extending outward from one broad side of the base. The fibers are arranged with a particularly low density while maintaining hook-engageability and usefulness as a fastening material.
Claims21
A touch fastener loop material comprising a non-woven web of fibers forming both a base and a field of hook-engageable loops of a tenacity of at least 1.1 grams per denier extending outward from one broad side of the base, wherein the fibers are distributed such that the loop material has a Loop Loft Density of between 0.6 and 1.3 gram per cubic inch as determined based on a thickness of the loop material measured according to ASTM D1777.
A touch fastener loop material comprising a non-woven web of fibers forming both a base and a field of hook-engageable loops of a tenacity of at least 1.1 grams per denier extending outward from one broad side of the base, wherein the fibers are distributed such that the field of loops has a Maximum Fiber Volume Ratio of between 5 and 25 percent, and the loop material has a Loop Loft Density of between 0.6 and 1.8 gram per cubic inch as determined based on a thickness of the loop material measured according to ASTM D1777.
