Abstract: A process for forming a nonwoven composite begins with forming a first nonwoven from a plurality of primary fibers and optionally binder fibers. A second nonwoven layer is formed from a plurality of bulking fibers and binder fibers. A thermoplastic elastomeric film is placed between the two nonwoven layers, the film containing a thermoplastic elastomeric polymer having an elongation at break greater than 300% and a max softening point (thermomechanical analysis end point) between 150° C. and 200° C. as tested according to ASTM E2347-04. The layers are needled together creating a plurality of holes in the thermoplastic elastomeric layer and moving a portion of the primary fibers from the first nonwoven layer into the second nonwoven layer. The needled stacked layers are heated to alter the median size of the holes in the thermoplastic elastomeric film forming the nonwoven composite.

Abstract: Compositions and methods for treating textile substrates to obtain superior liquid repellent properties are disclosed. Durable microscopic surface structures imparted to the fibrous substrate allow liquids to bead up and roll off of its surface. Mechanical abrasion or sanding techniques may be used to create the microscopic surface structures on the surface of a fibrous textile substrate, without substantially breaking fibers, followed by a chemical treatment using, for example, fluorocarbon-containing repellent compositions. Particles may be employed in combination with repellent compositions to achieve superior repellent properties. A property of the roughened surface fibers, the Roughness Factor, is used to characterize the microscopic surface structures on the treated textile surface. Treated textile substrates are disclosed which achieve superior water and oil repellency, even after multiple abrasion or laundering cycles.
