TEXTILES ATTACHED WITH LOW DENSITY POLYURETHANE FOAMS MADE USING A COMBINATION OF FROTHING AND BLOWING METHODS

摘要

Textiles backed with a polyurethane cushion are produced by applying a layer of frothed polyurethane-forming mixture to a surface of the textile. The mixture contains both water and a physical blowing agent. The layer expands due to the action of the water and the physical blowing agent and cures to form an attached cushion having a density of 176 g/L or less.
