METHOD FOR TEXTILE DYEING PREFERABLY FROM WOOL FIBER WITH ACTIVE DYES

摘要

FIELD: dye-boarding industry, in particular textile dyeing preferably from wool fiber.;SUBSTANCE: invention relates to low-temperature wool fiber textile dieing with active dyes. Method includes pretreatment of textile with organic nitrogen containing additive selected from group including amino acid or nitrogen containing enzyme or enzyme selected from oxidoreductases (e.g. peroxidase) at concentration of 0.2-0.5 % in respect to mass of material to be dyed. Dieing is carried out for 120-130 min. Claimed additions to intensify the dyeing process are not-toxic, environmentally friendly, and effective at low concentration.;EFFECT: method for dyeing with improved technological characteristics; dyed protein and cellulose fibers with increased color intensity.
