Abstract:
1. A composition for treating carpets, the composition comprising: a film forming polyurethane dispersion including (i) a first film forming polyurethane dispersion and (ii) a second film forming polyurethane dispersion, wherein the film forming polyurethane dispersion forms a film when applied to a polyester fiber carpet, and the film, upon drying, forms a topcoat on the polyester fiber carpet, wherein the first film forming polyurethane dispersion forms a hard component of the topcoat, and wherein the second film forming polyurethane dispersion forms a soft component of the topcoat; and a solvent for coalescing particles of a carpet colorant and causing the particles to flow into carpet fibers when the composition is applied to the polyester fiber carpet, wherein the composition seals and protects a portion of the polyester fiber carpet to which the colorant is applied such that, after the polyester fiber carpet is walked on by 30,000 steps and vacuumed by 600 strokes, the ΔE wherein the composition imparts wear resistance to a nylon carpet such that an average width of free ends of carpet fibers that form the nylon carpet increases by less than about 10% when the nylon carpet is subjected to a simulated wear test that includes contacting the carpet fibers to a steel bearing bar, covered with nylon, in a drum rotating at thirty-five rotations/minute for seventy-two hours; and wherein the composition is formulated as an aerosol spray.
