Abstract
Abstract A textile material for use in connection with a carrier includes a non-woven fibrous layer which has an irregular surface, and a plurality of separate, round, fiber aggregates, each composed of substantially spherically intermingled fibers. A multiplicity of connecting fibers connects the fiber aggregates to one another.

Claims Analysis
Total Claims: 35
Claim 1
Independent Claim
156 words
A textile material comprising a non-woven fibrous layer having an irregular surface formed by needle bonding a plurality of separate fiber aggregates, each aggregate having, prior to needle bonding, a substantially spherical to elongated shape with a smallest diameter of no less than 3 mm, said aggregate is formed from intertwined fibers which include fibers having a length of at least 15 mm, said aggregate also having a density ranging from about 0.01 to about 0.1 grams per cubic centimeter, the intertwining being such that a needle commonly used in needle processing technology to stitch material together may penetrate said aggregate and grip and withdraw a fiber from said aggregate free from encountering any substantial resistance by the aggregate so that the withdrawn length of fiber extends out of the aggregate without losing its cohesion with the aggregate; and a multiplicity of needle processed connecting fibers interconnecting said fiber aggregates to form said non-woven fibrous layer.
Claim 2
Dependent Claim
156 words
A textile material comprising a non-woven fibrous layer having an irregular surface formed by needle bonding a plurality of separate fiber aggregates, each aggregate having, prior to needle bonding, a substantially spherical to elongated shape with a smallest diameter of no less than 3 mm, said aggregate is formed from intertwined fibers which include fibers having a length of at least 15 mm, said aggregate also having a density ranging from about 0.01 to about 0.1 grams per cubic centimeter, the intertwining being such that a needle commonly used in needle processing technology to stitch material together may penetrate said aggregate and grip and withdraw a fiber from said aggregate free from encountering any substantial resistance by the aggregate so that the withdrawn length of fiber extends out of the aggregate without losing its cohesion with the aggregate; and a multiplicity of needle processed connecting fibers interconnecting said fiber aggregates to form said non-woven fibrous layer.
