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. Cathode is inserted into the first chamber, and anode is inserted into the second chamber, while cathode is located from membrane at the distance of 5-20 more than anode. The following components are added into water of the first chamber by means of feeders (g/l): sodium silicate 15-20, hydrogen peroxide 20-25, surfactant 2-3, table salt 30-60, powder of aluminium silicates 5-30 vol. %, to develop a dispersed mixture. 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 anode is 5-20 times less than potential applied to cathode; cotton fabric is charged into the first chamber. Fabric is impregnated at the temperature of 85-95C, mixing dispersed mixture in the first chamber; water is mixed in the second chamber. Fabric is steamed at the temperature of 100-105C for an hour in steaming device, washed with hot and cold water, squeezed. ^ EFFECT: simplification, reduced dimensions and cost of device, lower production costs. ^ 2 cl, 1 dwg |
