Abstract
Abstract A flocked, foam-coated, fibrous-reinforced, water vapor permeable, bacterial barrier having the appearance of fabric, and being capable of filtering bacteria is disclosed. The barrier comprises a microporous polyolefin film coated on at least one surface with a foamed latex polymer, flocked fibers on the exterior surface of said foamed latex polymer, and a web of spunbonded fibers on the exterior surface of the flocked, foamed latex polymer.
