摘要：A porous, breathable, polymer-coated fabric is produced by applying a layer offilm-forming flexible polyurethane solution to a carrier member; heating said layersufficiently to form a solidified film on said carrier member; cooling said film and carriermember; applying a second layer of film-forming polymer solution on the first film onthe member; applying to said second layer a fabric material; and heating the resultingstructure to form an unitary article comprised of the fabric and both polymer layers. Thecarrier member can be stripped from the first polymer layer. Plastic films can also beproduced.
