COMPOSITION FOR SEALING A COLORANT TO A SURFACE AND/OR FOR PROTECTING A SURFACE

摘要

A composition for treating a surface such as carpets. The composition includes a film forming polyurethane dispersion having first and second film forming polyurethane dispersions. The film forming polyurethane dispersion forms a film when applied to a surface such as a polyester fiber carpet, and the film, upon drying, forms a topcoat on the surface (e.g., the polyester fiber carpet). The first film forming polyurethane dispersion forms a hard component of the topcoat, and the second film forming polyurethane dispersion forms a soft component of the topcoat. The composition also has a solvent that coalesces particles of a surface colorant and causes the particles to flow into the surface, such as carpet fibers, when the composition is applied to the surface. The composition seals and protects a portion of the surface, such as polyester fiber carpet, to which the colorant is applied.

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 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 ΔECMC (l:c=2:1) of the portion of the polyester fiber carpet to which the colorant is applied is less than about 6.0, and the ΔCCMC of the portion of the polyester fiber carpet to which the colorant is applied is less than about −3.0 D, 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.
