Abstract
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.
