Abstract
Abstract A laminate structure, as in a carpet, in one form comprises a non-woven heat sealable fabric, heat sealed on one side, laminated with an adhesive to a facing layer of heat sealable fibers, applied as by an embossing roll which can be heated. The non-woven fabric can be a needle-punched assemblage of a scrim and fibers and the assemblage heat sealed on that side of the scrim from which the needles have emerged thus to lock the fibers into the scrim when heat sealing to provide a fibrous, non-heat sealed pad side of the assemblage. The adhesive can be a thermally responsive, i.e., a thermoplastic or thermosetting, film, powder or melt. In a modification a further backing can be present on the non-heat sealed pad side. Likewise, the second backing can be present. A non-slip structure is set forth.
