ABSTRACT:
An improved process for dyeing or printing water-swellable cellulosic fibers and mixtures of said cellulosic fibers with synthetic fibers by contacting the fibers throughout with a dye liquor or print paste which contains, as essential ingredients, water in an amount sufficient to swell the cellulosic fibers, a water-insoluble disperse dye and a water-soluble solvent for the disperse dye such as polyethylene glycol or boric acid esters of polyethylene glycols, and heating the contacted fibers to fix the dye, the improvement comprising the addition of from 0.5 to 5% by weight, based on the dye liquor or print paste, of a condensate of an aliphatic monocarboxylic acid of from 8 to 20 carbon atoms and a primary or secondary hydroxyalkylamine of up to 6 carbon atoms, which condensate may be ethoxylated with up to 20 moles of ethylene oxide per mole of condensate.
