Thermoplastic resin paste impregnated substrates

摘要

A process for manufacturing porous textile substrates impregnated with thermoplastic polymeric pastes, especially fleeces or mats, with subsequent gelling out of polymeric paste, which comprises penetrating impregnating one side of a textile substrate with an evacuated paste comprised of a vinyl polymer and/or copolymers of vinyl chloride, while effecting complete displacement of air through the paste and compactly impregnating said substrate.
