Claims
- 1. A tufted pile carpet comprising:
- a) a primary backing having a surface tufted with pile yarns and an underside to which a water permeable latex has been applied;
- b) an optional water permeable secondary backing having a surface and an underside, wherein the surface of the secondary backing is adhered to the underside of the primary backing; and
- c) an underlay having a surface and an underside, wherein the surface of said underlay is coated with a pressure sensitive adhesive which cures at ambient temperature and affixed to the underside of either the secondary backing or the primary backing, and said underlay comprises a nonlatex fabric, said fabric being substantially impervious to liquids,
- wherein said carpet is substantially impervious to liquids.
- 2. The carpet of claim 1 wherein the underlay is polyester, polyolefin, polytrimethylene terephthalate, nylon, wool, cotton, acrylic, jute, mixtures thereof, or mixtures with a cellulosic.
- 3. The carpet of claim 1 wherein the adhesive used to affix the underlay provides a lamination strength of at least 8.9 kg/m.
- 4. The carpet of claim 1 wherein the adhesive adheres the undelay to the primary or secondary backing immediately upon contact.
- 5. The carpet of claim 1 wherein the adhesive remains adhered to the underlay and the primary or secondary backing when wet by liquid.
- 6. The carpet of claim 1 wherein the pile yarns are polyamide, polyester, polyolefin, polytrimethylene terephthalate, wool, cotton, acrylic, or mixtures thereof.
- 7. The carpet of claim 1 wherein the underlay has in or on it a repellent finish comprising a fluorochenmical, silicone, wax emulsion, naturally occurring oil, alkylacrylate resin, hydrophobic alkylmethacrylate resin, or a mixture thereof.
- 8. The carpet of claim 7 wherein said fluorochemicals are selected from the group consisting of polyvinylidene fluoride; polytetrafluoroethylene; perfluoroalkylethyl acrylates; perfluoroalkylethyl methacrylates; mixtures of the same; and blends of the foregoing compounds and polymers with polyalkyl acrylates, polyalkylmethacrylates, wax emulsions, and copolymers of vinylidene chloride, vinylidene fluoride, tetrafluoroethylene, perfluoroalkylethyl acrylates, and perfluoroalkylethyl methacrylates.
- 9. The carpet of claim 7 wherein said fluorochemical is selected from the group consisting of fluoroalkyl citrate urethane, a fluoroalkyl methacrylate/2-ethylhexyl methacrylate/2-hydroxyethyl methacrylate/N-methylolacrylamide copolymer, a fluoroalkyl methacrylate/lauryl methacrylate/N-metholacrylamide copolymer, a dimethylaminoethyl methacrylate/acrylic acid copolymer, a chloroprene/dichlorobutadiene copolymer, and a blend thereof.
