Composition for sealing a colorant to a surface and/or for protecting a surface

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 first film forming polyurethane dispersion and the second film forming dispersion are in a ratio of from about 1:1 to about 1:2, 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 protects against color change in a portion of polyester fiber carpet such that, after the polyester fiber carpet is walked on by 30,000 steps and vacuumed by 600 strokes, the ΔECMC (l:c=2:1) of the portion of polyester fiber carpet is less than about 3.0, and the ΔCCMC of the portion of the polyester fiber carpet is less than about −2.0 D, and
• wherein the composition imparts the wear resistance to nylon carpet fibers having an initial average width of about 0.118 inches such that the average width of free ends of the nylon carpet fibers increases by less than about 0.010 inches when the nylon carpet fibers are subjected to a simulated wear test that includes contacting the nylon carpet fibers to a steel beating bar, covered with nylon, in a drum rotating at thirty-five rotations/minute for seventy-two hours.

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 is 12 wt. % or less of the composition, 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, 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 no colorant is applied such that, after the portion of the polyester fiber carpet is walked on by 30,000 steps and vacuumed by 600 strokes, the ΔECMC (l:c=2:1) of the no colorant portion of the polyester fiber carpet is less than about 3.0, and the ΔCCMC o the no colorant portion of the polyester fiber carpet is less than about −2.0 D, and
• wherein, the composition seals the colorant to the polyester fiber carpet such that the ΔECMC (l:c=2:1) of the portion of the polyester fiber carpet to which the colorant is applied is less than about 1.55 after the portion of polyester fiber carpet to which the colorant is applied is vacuumed by 100 strokes, and
• 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 beating bar, covered with nylon, in a drum rotating at thirty-five rotations/minute for seventy-two hours.
