Treating composition containing fluorochemical compound mixture and textiles treated therewith

A treating composition comprising

• (a) at least about 0.7 parts by weight of a compound having the formula ##STR4## where R.sub.f is a fluorinated aliphatic radical;
• A is a divalent radical obtained by eliminating the carbonyl groups of a dibasic organic acid or an organic anhydride selected from the group consisting of tetrachloro phthalic, tetrabromo phthalic and chlorendic;
• and
• M is a cation selected from the group consisting of NH.sub.4 .sup.+, Na.sup.+, K.sup.+, Li.sup.+, H.sup.+, or a protonated alkyl amine having from 1-6 carbon atoms in the alkyl group;
• (b) at least about 0.1 part by weight of a normally liquid or low melting solid, water soluble or dispersible, fluoroaliphatic radical-containing poly(oxyalkylene) compound, or composition comprising a mixture of such poly(oxyalkylene) compounds, said poly(oxyalkylene) compound having one or more of said fluoroaliphatic radicals and one or more poly(oxyalkylene) moieties, said fluoroaliphatic radicals and poly(oxyalkylene) moieties being bonded together by hetero atom-containing groups or organic linking groups or combinations of said groups;
• and
• (c) the balance of 100 parts of a substrate-inert liquid vehicle capable of dissolving and/or dispersing said compound and said fluoroaliphatic radical-containing poly(oxyalkylene) in at least the amounts specified.
