Abstract
There is disclosed a process for imparting to cellulose or cellulose-containing textile materials durable press properties by treating cellulose or cellulose-containing textile materials by applying to the textile materials a treating composition of (a) about 1-25% by weight, based on dry weight of the material, of an activated water-soluble bisvinyl compound and (b) about 0.2-25% by weight, based on dry weight of material, of (1) a copolymer having a Tg<20.degree. C., said copolymer being produced from a monomer mixture containing (i) about 0.25-99.5% by weight, based on weight of copolymer, of a quaternary monomer obtained by reacting an epihalohydrin having the formula, ##STR1## with an ammonium salt having the formula CH.sub.2 .dbd.C(R)C(O)O-A-N(CH.sub.3).sub.2 HY, wherein R is H or methyl, A is a (C.sub.2 -C.sub.6) alkylene group having at least two carbons in a chain between adjoined O and N atoms or A is a polyoxyethylene group, (CH.sub.2 CH.sub.2 O).sub.n CH.sub.2 CH.sub.2, wherein n is an integer of at least 1, X is iodine, bromine, or chlorine, and Y is an anion, and (ii) at least one copolymerizable ethylenically unsaturated monomer, or (2) the reaction product of a copolymer of said ammonium salt and the epihalohydrin, and (c) sufficient aqueous base solution to effect a pH of about 9-12; drying the treated textile material; and heating the treated textile material at a temperature and for a time sufficient to cure the treating composition.
