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