Abstract
Textiles, particularly carpets, are endowed with oil and water repellency and soil resistance by treatment thereof with certain detergent-compatible fluorochemical compounds which can also be used in conjunction with anionic or nonionic detergents to provide cleaning/treating compositions for cleaning such textiles simultaneously with the treatment. The textile treating compositions of the invention comprise certain detergent-compatible fluorochemical compounds which are dissolved and/or dispersed in a suitable liquid vehicle. The textile treating/cleaning compositions of the invention also contain an anionic and/or a nonionic detergent.

A composition comprising a liquid vehicle containing from about 1% to about 25% by weight of a detergent-compatible organic fluorochemical compound containing about 10 to 60 weight percent carbon-bonded fluorine and having the formula (R.sub.f Q).sub.e (XCO).sub.m A(COOM).sub.p where R.sub.f is fluorinated aliphatic radical of at least three carbon atoms, "Q" is a divalent linking group, "M" is a cation selected from NH.sub.4.sup.+, Na.sup.+, K.sup.+, Li.sup.+, H.sup.+ or is a protonated alkyl amine having from 1-6 carbon atoms in the alkyl group, "A" is a polyvalent organic radical having a valency of m + p and is the residue of a polybasic organic acid or an organic anhydride, "X" is NR (wherein R is hydrogen or an alkyl group of from 1 to 14 carbon atoms), N or O and e, p and m are integers of 1 or 2.
A composition comprised of a liquid vehicle containing (1) from about 1% to about 25% of a detergent-compatible fluorochemical compound containing from about 10 to about 60 weight percent carbon-bonded fluorine and having the formula (R.sub.f Q).sub.e (XCO).sub.m A(COOM).sub.p where R.sub.f is fluorinated aliphatic radical of at least three carbon atoms, "Q" is a divalent linking group, "M" is a cation selected from NH.sub.4.sup.+, Na.sup.+, K.sup.+, Li.sup.+, H.sup.+ or is a protonated alkyl amine having from 1-6 carbon atoms in the alkyl group, "A" is a polyvalent organic radical having a valency of m + p and is the residue of a polybasic organic acid or an organic anhydride, "X" is NR (wherein R is hydrogen or an alkyl group of from 1 to 14 carbon atoms), N or O and e, p and m are integers of 1 or 2, and (2) compatible non-ionic or anionic detergent, said detergent being water dispersible at concentrations of at least 1% by weight and being capable of drying to a non-oily, non-tacky residue, the weight ratio of said detergent to said fluorochemical compound being on the order of 1:1 to 2:1.
