Abstract
Abstract Carpets having a primary backing and a pile consisting essentially of polyamide fibers stitched into the primary backing are described. The fibers are characterized in being stain resistant and the backing is characterized in being impervious to water. The carpet is easy to maintain since its fibers are stain resistant and water can be used to clean the carpet without fear of the water penetrating the backing and being absorbed by the padding, a situation which leads to rotting of the carpet and wooden floors.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
96 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 sulfonated phenol- or naphthol-formaldehyde condensation product to render the carpet stain resistant and said adhesive composition contains a fluorochemical in an amount sufficient to render said primary backing substantially impervious to water.
Claim 2
Dependent Claim
96 words
