Abstract
A process for improving the dyeability of fabrics or fibers comprising polyhydroxylzed polymers by the use of at least one compound selected from the group consisting of a compound of the formula; ##STR1## and mixtures thereof, wherein R, R', R" and R"' are lower alkyl radicals having 1 to 20 carbon atoms and X is selected from the group consisting of sulfate, sulfonate and halide. The process requires that a dry cauticized fabric be treated with a dilute solution of a lower alkyl ammonium salt so that the fabric contains less than about 50% by weight of water prior to curing.
