Abstract
A direct application process by spray, pad, foam, flood or roller coating of a chemical composition of Novolak resin, polymethacrylic acid, sulphated or sulphonated surfactants and a fluorochemical to provide stain resistance/release to fibrous material, particularly nylon and wool carpets. The finish offers desirable oil, water and dry soil repellency and acid dye stain release without adverse effect on texture (handle) and pile opening. The invention relates to the use of diethanolamine lauryl sulfate as a foaming surfactant that also has stain release property against artificial coloring material commonly found in food and beverages.
