Patent ID: 7815690

Claim:
A method of providing stain resistance and soil resistance to a pre-wetted carpet comprising application in a single step to said pre-wetted carpet of the composition of Formula 1 wherein D is at least one vinyl monomer selected from the group consisting of aryl olefin, vinyl ether, allyl ether, alpha olefin and diene; each M is independently H, NH 4 , Ca, Mg, Al, or a Group I metal; R is H, a C 1 -C 16 alkyl group, or an arylalkyl group; R f is a fully fluorinated straight or branched C 2 to C 20 aliphatic radical, or mixture thereof, which is optionally interrupted by at least one oxygen atom; x is 1 to about 10, or a mixture thereof; k and h are each independently a positive integer; i and j are each independently a positive integer, or i is zero and j is a positive integer; such that the molar ratio of k to (h+i+j) is from about 3:1 to about 1:3, and the molar ratio of h to (i+j) is from about 1:99 to about 22:78; wherein said composition is applied as an aqueous dispersion or solution which is applied to said pre-wetted carpet at a wet pick up of from about 20% to about 60%; further comprising the steps of drying said pre-wetted carpet at from about 150° F. to about 180° F. and curing said pre-wetted carpet at from about 250° F. to about 300° F.
