Abstract
Aqueous liquids, such as water, can normally penetrate through conventional carpet. Thus, in cases where water is spilled on conventional carpet, it typically seeps through and ultimately reaches the flooring below. This trapped water can lead to bacterial or fungal growth which can further cause odors and/or deterioration of the carpet backing or flooring. This invention relates to a technique for treating carpet to render it impervious to aqueous liquids. This invention specifically discloses a process for treating carpet which is comprised of a pile and a backing to render said carpet impervious to aqueous liquids, said process comprising the steps of (1) coating the bottom side of said backing with a water-resistant coating composition which is comprised of (i) a latex of a polymer which is comprised of repeat units which are derived from (a) about 30 weight percent to about 84 weight percent vinyl aromatic moochers, (b) about 15 weight percent to about 65 weight percent alkyl acrylate moochers and (c) about 1 weight percent to about 6 weight percent unsaturated carbonyl group containing moochers, (ii) a coalescing solvent and (iii) a thickener; and (2) allowing the water-resistant coating composition to dry on the bottom side of said backing to produce the treated carpet which is impervious to aqueous liquids.
