An agent effective for oleophobizing and hydrophobizing textiles is an aqueous anionic dispersion which comprises water and

Aqueous anionic dispersion

Hydrophobic textile materials exhibit reduced tendency to static charge buildup, significantly improved absorbency and reduced soiling tendency when treated with a water-dispersible polyester having structural units of the formula ##STR1## wherein A is, on statistical average, 80 to 100 mol percent of p-phenylene and 0 to 20 mol percent of divalent moieties of the formula ##STR2## and wherein G is, on statistical average, 30 to 90 mol percent of linear or branched divalent alkane moieties having 3 to 6 carbon atoms which may be interrupted by 1 or 2 oxygen atoms, 10 to 30 mol percent of divalent polyether moieties having an average molecular weight of 1,000 to 3,000, and up to 50 mol percent of ethylene moieties, and R is a straight-chain or branched alkyl or alkenyl having 6 to 8 carbon atoms.
