Abstract (en)
[origin: WO9850619A1] A process is described which imparts exceptional antisoiling, anti-staining and repellent properties to carpets. The process makes use of a water-based exhaustion process wherein the water-based treating solution contains (1) glassy fluorochemical material, glassy hydrocarbon material, or combinations thereof; (2) a stainblocking material; (3) a polyvalent metal salt, acid, or combinations thereof; and (4) water. Subsequent to exhaustion, the wet treated carpet is heated, usually in a steaming step, rinsed, and dried in a dry heat oven.
