Abstract
A drapable, water vapor permeable, wind and water resistant composite fabric including a fabric substrate, a layer of a foamed water vapor porous adhesive in the surface area of one side of the fabric substrate and a layer or fabric material suitable for exposed use on the other is provided. The fabric material is preferably a layer of flocked fibers. The cellular structure of the foamed adhesive permits water vapor to pass through, however, wind and liquid water is inhibited from passing through the foam barrier. The foamed adhesive is inhibited from penetrating deeply into the fabric substrate during manufacture by an adhesive barrier material on the fabric which may be substantially removed during later processing. The resultant fabric is drapable and particularly suited for use in apparel, replacing two or more single purpose fabric layers within one multipurpose fabric layer.
