    • 1,160,723. Coated porous textiles. L.W.S. NOMINEE CO. Ltd 22 Aug., 1966 [1 Sept., 1965], No. 37449/66. Heading B2E. [Also in Divisions C6 and D1] An imitation leather material is made from a porous textile substrate such as a non-woven wool felt, or a woven and felted wool fabric, to which an elastomeric polymer or plastic surface layer, such as polyether or polyester urethane or polyvinyl chloride, is applied in a liquid state. The free ends of the hairs of animal skins are straighteend by electrostatic or other means and embedded in the polymeric layer. The polymeric layer is then partially dried and/or cured and the animal hairs pulled out leaving a surface with tiny holes or follicles after which drying and/or curing is completed. Alternatively, the drying and/or curing can be completed with the animal hairs still embedded in the polymeric layer and the hairs then cut off flush with or just above the surface, leaving the hair ends embedded in the polymeric layer. In both forms the material is finally dressed as by buffing to produce a smooth leather-like surface.
