Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
133 words
A fluorochemical finish composition for imparting antisoiling protection and lubricity to textile fibers and which is stable to the high shear environment of a finish application system, said composition having a pH less than 6 and being a uniform aqueous emulsion containing about 2 to 30 weight % active ingredients and being substantially free of fluorine-containing surfactants, said active ingredients comprising on a dry solids weight basis about: (a) 1 to 34.9% of nonionic fluorochemical textile antisoilant; (b) 65 to 95% of nonionic water-soluble or water-emulsifiable lubricant; (c) 0.05 to 15% of quaternary ammonium or protonated amine cationic surfactant; and (d) 0.05 to 15% of nonionic surfactant; the weight ratio of antisoilant to total surfactants being about 0.5 to 20:1 and the weight ratio of lubricant to antisoilant being about 2 to 25:1.
Claim 2
Dependent Claim
28 words
Composition according to Claim 1 wherein the fluorochemical textile antisoilant is selected from the group consisting of a fluorocarbonylimino biuret, a fluoroester, a fluoroester carbamate, and a fluoropolymer.
