FIELD: dye-finishing production.
SUBSTANCE: the present innovation deals with delivering dyeing composition heated up to about 35-40°C into the tank with ultrasound emitter at frequency being 104-106 Hz followed by the impact upon it for the period of about 1-5 min; guiding it into the tank for dyeing supplied with ultrasound emitter at frequency ranged 104-106 Hz with a substrate located in it, which was pre-subjected for ultrasound impact in this tank in the mentioned frequency range; availability of a substrate in the mentioned activated dyeing composition at excessive pressure of about 0.5-1.0 atm for the period of about 3-15 min followed by washing with water subjected to ultrasound impact in the tank for water activation in frequencies ranged 104-106 Hz followed by drying. Waster water should be guided into the tank for water purification supplied with ultrasound emitter at frequency being 104-106 Hz at excessive pressure ranged 2.5-5.0 atm with subsequent return of the purified water into the cycle of dyeing process. The innovation provides intensification of dyeing process and shortened expenses of dyestuff and supplementary substances.
EFFECT: higher efficiency.
