Aqueous cleaning compositions providing water and oil repellency to fiber substrates

Claim 1

Aqueous cleaning compositions which impart oil and water repellent characteristics to fibrous substrates which comprise: (a) a fluoroaliphatic oligomer or polymer according to the general formulae (3): C.sub.a F.sub.2a+a N(CH.sub.3)(W).sub.3 (A).sub.n B.sup.31` X.sup.+( 3) in which: B is a water soluble group selected for sulfate, sulfonate, carboxylate, phosphate, phosphonate or halogen group; W is a lower alkyl group especially a --CH 2 --, --CH 2 CH 2 -- and/or --CH 2 CH 2 CH 2 --; A is an ethoxy (OC 2 H 4 ), propoxy (OC 3 H 6 ), and/or butoxy (OC 4 H 8 ) or is a mixture of two or more such groups; X+ is a salt forming organic counterion, or an inorganic counterion; n represents a value of between 1 and 8; a represents a value of between 1 and 12, (b) anionic surfactant selected from alkyl sulfates, alkyl benzene sulfates, and alkane sulfonates as well as salt forms thereof; (c) organic solvent; (d) water; and further optionally; (e) one or more additives selected from preservatives, coloring agents; fragrances, anti-foaming agents, pH adjusting agents, buffer compositions, anti-soiling agents and resoiling inhibitors, chelating agents, optical brighteners, further solvents or surfactants, one or more further fluorosurfactant compositions, and one or more nonionic surfactants selected from alkoxylated primary alcohols and alkoxylated secondary alcohols as well as salt forms thereof.
