ABSTRACT:
A continuous dyeing, space dyeing or printing process for dyeing cationic dyeable polyamide fibers comprising the steps of applying a premetalized acid or acid dye to the fiber at a pH of 2.5 and below, and the dyed polyamide fiber resulting therefrom. The dyeing process generates cationic dyeable polyamide fiber dyed or printed in light to deep shades without bleeding and without producing badly contaminated dye water effluent.
