Patent ID: 7329367

Claim:
A fibrous substrate having durable soil release, soil resist, stain resist, water and oil repellency and softness, the fibrous substrate having applied thereto a combination of five different components a), b), c), d) and e), in weight % based on the weight of the fibrous substrate: a. at least 0.01% of an anionic or non ionic fluorochemical to provide water and oil repellency, said fluorochemical being derived from an anionic or non ionic emulsion or dispersion of a fluoroalkyl acrylate copolyrner, fluorocarbon polymer or fluoroacrylate copolymer; b. at least 0.01% of a crosslinking agent to provide durability in the substrate, said crosslinking agent being a blocked isocyanate, oxazoline, styrene-acrylate, or aziridine polymer or copolymer; c. at least 0.01% of a soil release agent to provide soil release in the substrate, said soil release agent being a polyacrylate emulsion based on a copolymer comprising methylmethacrylate and ethyl acrylate; d. at least 0.01% of a soil resist agent to provide soil resistance in the substrate, said soil resist agent being a polymer of methacrylic acid or acrylic acid, and e. at least 0.01% of a stain resist agent, said stain resist agent comprising a sulfonated aromatic condensation resin selected from the group consisting of novolak, resole and naphthalene condensation resins.
