## Abstract

A composition for treating carpets. The composition seals and protects a portion of a polyester carpet to which a colorant is applied such that, after the polyester 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 carpet to which the colorant is applied is less than about 6.0. The ΔCCMC of the portion of the polyester carpet to which the colorant is applied is less than about −3.0 D. 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.
