METHOD FOR CARBONISATION OF WOOL FIBRES AND DEVICE FOR ITS REALISATION Russian patent published in 2010 - IPC D06B3/02 

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 50-125 g/l, powder of aluminium silicates 5-30 vol. %, creating dispersion mixture (DM); wool fibres are loaded into the first chamber; DC voltage is supplied to electrodes, developing 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. Wool fibres are impregnated and soaked for 10-25 minutes; at the same time DM is mixed, as well as water in the second chamber; fibres are discharged from chamber, squeezed, dried; thermal treatment is carried out at 100-110°C, charged into the first chamber, washed with cold water, remains of sulfuric acid are neutralised in fibres in 2% solutions of soda, or ammonia or acetous sodium, again washed, discharged from the first chamber, squeezed.

EFFECT: simplification of device, reduced production costs.
