Anionic surfactants - added to cationic dye baths for anionically modified synthetic fibres, esp polyacrylonitrile

摘要

Level shades are obtd. by dyeing anionically modified synthetic fibres, esp. polyacrylonitrile, also polyester and polyamide fibres modified with COOH-, sulpho-, sulphate- or phosphate gps. with cationic dyes in the presence of 2.5-5 (esp. 3) wt. % anionic surfactants, /wt. textile, pref. alkyl sulphates and/or alkyl sulphonates and/or alkylaryl sulphonates. Pref. the anionic surfactants are added with the dye at max. dyeing esp. boiling-, temp.
