Abstract:
A method of making garment material, the method having the steps: applying coagulant (34) to a substrate (32); applying a foam (38) of the polymeric material to the substrate (32); allowing the coagulant (34) to coagulate some of the foam (38); and removing uncoagulated foam (38) from the substrate (32) to leave a layer of coagulated polymeric material on the substrate (32).
Abstract:
Disclosed is a process for making a two or more component foam composite obtained by adhesion of a polyurethane foam onto a substrate comprising the steps of frothing an aqueous polyurethane formulation; applying the froth to a substrate and drying the froth into a foam wherein the foam has a dry density of 35 kg/m to 160 kg/m (2.2-10 Ibs/cft). The process allows the production of foam backed textiles without the need for a flame lamination step or the need for an adhesive layer between the textile and the foam layer and is optionally optimized for superior handling properties for covering polyurethane molded foam cushions.
