  • Dyeable polyolefin backing for tufted surface coverings
    Patent number: 4014645
    Abstract: The dye receptivity of polyolefin materials, used as backings for tufted surface coverings such as carpets and upholstery fabrics, is improved by coating the polyolefin material with a self-curing polymeric binder containing a quaternary ammonium salt.
