ABSTRACT:
A procedure is provided for producing a laminate having a textile backing, a crushed, thermoset plastic foam bonded thereto, and a transparent polymeric film, preferably also a thermoset, which may be printed or colored overall overlying the foam. The structure is self-bonded, i.e., no adhesive is used to bond the laminate to one another. The preferred procedure is to apply a thin layer of foamed latex of a thermosettable polymer on a textile followed by drying the foam, the thickness of the foam being between about 10 mils and 150 mils. The transparent film, preferably thermosetting, is suitably formed by casting a latex upon a release surface such as silicone release paper and drying the same without causing thermosetting (if a thermosettable polymer is utilized). The dry film, still on the release paper, is then suitably coated or printed with a decorative design. The decorated side of the film is then placed against the dried foam layer and bonded thereto by pressure. The thermosetting may be done simultaneously with bonding or subsequently thereto.
