  • Aqueous emulsion composition, method of backing carpet, and carpet
    Patent number: 6706800
    Abstract: A method of backing a carpet, comprising the steps of applying, to the back of a carpet, an aqueous emulsion composition prepared by adding a polyisocyanate compound to a specific high-solid-content emulsion compound, laminating a fabric to the composition-applied surface of the carpet, and thermally curing and then drying the emulsion composition applied; and a carpet backed by this method. The aqueous emulsion composition for use in this method is highly safe and easy to handle. Moreover, even when this emulsion composition is applied to the back of a carpet to a thickness of as great as 1 mm or more, it is cured and dried in a short time. The shortcomings in the conventional methods using aqueous emulsions can thus be successfully overcome by this method.
