FIELD: textiles, paper.
SUBSTANCE: method of dyeing wool fibre with active dyes by its preliminary modification in the aqueous solution, extracting, processing with dyeing solution, washing, neutralisation, washing and drying, when the preliminary modification of fibre in the aqueous solution is carried out by exposure to ultrasound at a frequency of 20-22 kHz, power of 3.0-6.0 kW for 3-10 minutes.
EFFECT: significant reduction in damage of the wool fibre, increase in dyeing intensity and reduction in processing duration.
