Anionic dyes can be used in dyeing of acrylic fibers with cationic nature (Creslan, Acrilan) or in case of acrylic fibers subjected to introduction of such basic groups into the polymer macromolecules by chemical treatments. In this paper are presented the possibilities of acrylic fibers dyeing with anionic dyes by pre-treatment, which lead to chemical structure modification. The samples treated with urea in addition with sodium hydroxide, hydrogen peroxide, ethylene carbonate (EC) and ethylene alcohol (EA) were further dyed with anionic dyes. A comparison was made between the colour intensity of acrylic samples pre-treated and dyed and that of acrylic fibers dyed without any chemical treatment. Experiments were made considering the influence of pre-treating time, urea concentration and additive concentration. Results obtained showed a good level of dyeing and high crocking and washing fastness.
