  • Tufted carpet with meltable-film primary-backing component
    Patent number: 4035533
    Abstract: A low-melting point layer of thermoplastic synthetic film is superimposed upon the rear side of a primary backing layer. Pile-forming yarns are then tufted from this rear side through both of these layers to form at the front side of the primary backing layer a pile, while forming at the exposed rear side of the film layer respective loops. The film layer is then exposed to heat, causing it to melt and to bond the loops to the primary backing layer.
