Abstract: Process for lowering the dyestuff affinity of fibre materials manufactured from polyacrylonitrile of copolymers containing acrylonitrile consisting in treating or printing the fibre materials before dyeing with aqueous baths respectively aqueous pastes which contain water-soluble polyamides which have been obtained by reaction of aliphatic polyamines of formula

WHEREIN R and R1 independently of one another represent hydrogen, a C1 - C5-alkyl group or a hydroxyalkyl group with 1 3 C-atoms, X denotes a divalent optionally substituted aliphatic residue with 1 - 6 C-atoms and n represents an integer from 1 4, with Alpha , Beta -unsaturated aliphatic monocarboxylic acids or aliphatic polycarboxylic acids which optionally contain heteroatoms.
