<p>Fibres of acrylonitrile (co)polymers are dyed with solns. of basic and/or disperse dyes in non-swelling solvents or solvent mixtures free of swelling agents at a dyeing temp. near the b.pt. of the solvent, and above 50 degrees C. The acrylonitrile (co)polymer fibres are dyed rapidly, as a good penetration of the dye in a relatively short time is obtained. The dyed fibres can be rapidly dried.</p> |
