Abstract
Abstract Carpets having stain resistant pile fibers and a backing that is substantially impervious to water are described. The imperviousness of the backing prevents water from passing through the carpet and into the underpad where its presence causes rotting and mildewing of the underpad and carpet components, and thus, permits the carpet to be washed with generous amounts of water without wetting the underpad. Also, aqueous substances which spill onto the carpet will not penetrate the carpet and wet the underpad.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
93 words
A carpet comprising a primary backing stitched with closely spaced loops or cut loops of nylon 6 or nylon 66 yarn which extend upwardly from the top surface of the primary backing to form a pile, wherein the underside of the primary backing is coated with a carpet backing adhesive composition, characterized in that said yarn is coated with a sufficient amount of a fluorochemical to improve the soil resistance of the carpet and said adhesive composition contains a fluorochemical in an amount sufficient to render said primary backing substantially impervious to water.
Claim 2
Dependent Claim
93 words
A carpet comprising a primary backing stitched with closely spaced loops or cut loops of nylon 6 or nylon 66 yarn which extend upwardly from the top surface of the primary backing to form a pile, wherein the underside of the primary backing is coated with a carpet backing adhesive composition, characterized in that said yarn is coated with a sufficient amount of a fluorochemical to improve the soil resistance of the carpet and said adhesive composition contains a fluorochemical in an amount sufficient to render said primary backing substantially impervious to water.
Claim 3
Dependent Claim
14 words
The carpet of claim 1 wherein said adhesive composition includes a carboxy styrene-butadiene latex.
Claim 4
Dependent Claim
12 words
The carpet of claim 1 wherein said fibers are nylon 66 fibers.
Claim 5
Dependent Claim
11 words
The carpet of claim 3 wherein said fibers are staple fibers.
