Abstract:
1. A method of manufacturing substantially waterproof moisture vapor permeable cover material comprising the step of: a. providing a hydrophilic fabric layer comprising a nonwoven material, or a combination of woven and non-woven materials, including two layers with an inner layer of lower hydrophilicity and an outer layer of greater hydrophilicity; b. applying an adhesive to the fabric layer; c. applying flocked fibers to the adhesive layer to form an inner side of the cover material designed to contact an item to be covered; and d. extrusion coating a substantially waterproof, moisture vapor permeable polymeric top layer to the fabric layer on the side opposite the adhesive and flocked fibers to form an outer side of the cover material configured to be exposed to an external environment, and said moisture vapor permeable polymeric top layer being extruded on said fabric, the outer layer of fabric being adjacent the moisture vapor permeable polymeric top layer.
