A hydrophilic polyurethane composition comprising a reaction product of: n 1. 10 to 45 weight percent of an organic diisocyanate and, n 2. 35 to 89 weight percent of a compound containing one or two active hydrogen atoms selected from: n A. 75 to 100 weight percent of a compound of the general formula: n n R--(O--C.sub.x H.sub.x).sub.n -OH n n wherein n R is hydrogen or a hydrocarbon radical containing from 1 to 20 carbon atoms; n X is a number from 2 to 4; n n is a number to indicate that the molecular weight is between 300 and 10,000; and, n B. 0 to 25 weight percent of a diol and, n 3. 1 to 25 weight percent of a nitrogen-containing compound of the general formula: ##STR1## wherein R' is an alkyl radical containing from 1 to 5 carbon atoms; n X 1 and X 2 are hydroxyalkyl or amino alkyl radicals with the proviso that the overall ratio of NCO/active H is from about 0.7 to about 1. The composition when applied to textiles provides outstanding soil-release and anti-soil redeposition properties particularly with fibers and fabrics made of polyester and polyester blends. |
