Abstract
Abstract A flocked foam having an embossed pattern provided by a high-frequency welder is disclosed. The foam comprises a partially cross-linked foam substrate (10 to 75% gel fraction in boiling toluene for 15 hours) formed from a 1,2-polybutadiene resin or a polymer blend including a 1,2-polybutadiene resin as one component thereof, and modacrylic pile fibers or a mixture thereof with other pile fibers flocked on the surface of the foam substrate.
