Reactive dyeings on textile materials containing cellulose fibers are aftertreated with aqueous solutions of benzylated resins which are obtainable

Aftertreatment of reactive dyeings on cellulose fibers

Dyed or printed synthetic fibers or materials consisting of synthetic fibers or of a mixture of synthetic fibers with other fibers are aftertreated with aqueous solutions which contain from 0.2 to 20 g/l of a mixture of one or more surfactants and a reductonate. The pH of the liquor is brought to above 8 and the aftertreatment is carried out at from 40.degree. to 100.degree. C.

After-treatment of dyed or printed synthetic fibers

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 which maintains swelling of the cellulose if water is removed and which is a solvent for the disperse dye, and heating the contacted fibers to effect fixation of the dye, the improvement comprising using as water-soluble solvent a mixture of
