Abstract
Abstract The invention relates to a novel anticrease finishing composition which comprises at least (A) an O-cyanoethylated compound of the formula (1) R(O--CH.sub.2 CH.sub.2 CN).sub.n, wherein R is an n-valent aliphatic, cycloaliphatic or araliphatic radical, and n is 1 to 5, and (B) a carboxylated polypropylene oxide adduct, or salt thereof, which adduct is obtainable from (a) an aliphatic diol having an average molecular weight of at most 2600, (b) an aliphatic dicarboxylic acid, or anhydride thereof, containing 4 to 10 carbon atoms, (c) an adduct of propylene oxide and an at least trihydric aliphatic alcohol containing 3 to 10 carbon atoms, and (d) a fatty acid containing 8 to 22 carbon atoms, and optionally, (C) an aliphatic alcohol containing 5 to 18 carbon atoms, a siloxane-oxyalkylene copolymer, or a mixture thereof, and/or (D) a polar solvent. The novel composition is used in dyeing or whitening textile material which contains polyester fibres.
