METHOD FOR COOKING OF COTTON FABRICS Russian patent published in 2007 - IPC D06B3/10 

FIELD: textile industry, in particular, cotton fabric cooking technology used in textile material dyeing process.

SUBSTANCE: method involves dividing fabric cooking reservoir of material washing machine, wherein fabric is impregnated, into two chambers by means of partition featuring properties of fine filter for water; introducing electrodes into said chambers; filling with water, said chamber with negative electrode, which is defined as cathode chamber, being filled with water containing (mg/l): sodium nitrate 3-5; sodium bisulfate 2-3; surfactant 1-2; charging the same cathode chamber with edible salt in an amount of 30-60 g/l; directing running water through chamber incorporating positive electrode; supplying electrodes with electric potential difference of 5-35 V; charging fabric into cathode chamber; impregnating fabric with cooking solution of indicated composition; squeezing fabric to moisture content of 100-110%; boiling in boiling cooking apparatus under saturated steam atmosphere at temperature of 100-105 C during 1 hour; washing with hot and cold water in material washing machine.

EFFECT: reduced expenses for cotton fabric cooking process, and improved safety conditions during fabric cooking process.
