METHOD FOR DYING OF FIBROUS MATERIALS AND DEVICE FOR ITS REALISATION Russian patent published in 2010 - IPC D06B3/02 D06P1/00 

FIELD: textile industry.

SUBSTANCE: in device reservoir is divided into the first chamber and the second chamber of equal volumes by electroconductive and grounded membrane; anode is inserted into the first chamber, and cathode is inserted into the second chamber, while anode is located from membrane at the distance of 5-20 more than cathode. The following components are added into water of the first chamber (g/l): salts of sulfuric acid 5-30, dye 30-50, powder of aluminium silicates 5-20 vol. %, producing a dispersion mixture (DM). Fibrous materials are charged into the first chamber; DC voltage is applied to cathode and anode to create intensity of electric field with value of 50-200 V/m; besides potential applied to cathode is 5-20 times less than potential applied to anode. Fibrous materials are soaked at the temperature of 100°C for 0.3-0.6 hr; DM is mixed in the first chamber. Water is mixed in the second chamber. Fibrous materials are washed, discharged from the first chamber, squeezed.

EFFECT: reduced dimensions of device, lower production costs.
