Abstract

1,246,757. Dyeing polyamides. CHEMIEFASERKOMBINAT SCHWARZA WILHELM PIEK VEB. 6 May, 1970, No. 21881/ 70. Heading D1B. [Also in Division C3] The exhaustion of the dye from a non- aqueous dyebath used for dyeing polyamides is increased by adding to the dyebath an ester of an unsaturated aromatic carboxylic acid and/or a derivative of an aromatic ketone. The non-aqueous medium is preferably a chlorinated hydrocarbon, the ester is preferably a #-cyano-#-phenyl-acrylic acid alkyl ester with 1 to 6 carbon atoms in the alkyl group and the aromatic ketone preferably a 2-hydroxy-4- alkbxy-benzophenone with 5 to 18 carbon atoms in the alkoxy radical, the polyamides is preferably a polycapronamide.
