METHOD FOR DESIZING OF COTTON FABRICS AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2007 - IPC D06B3/10 

FIELD: textile industry, in particular, cotton fabric desizing process and equipment.

SUBSTANCE: method involves dividing bath adapted for desizing of cotton fabrics into two chambers by means of partition featuring the properties of fine filter for water; introducing electrodes into both of said chambers and filling bath with water; introducing into bath chamber of larger size incorporating positive electrode and used as anode chamber sulfites in an amount of 3-15 g/l, powder of amphoteric aluminosilicates: montmorillonite, beidellite, nontronite, kaolinite, halloysite, talc in an amount of 1-30 g/l, each component being introduced individually or in random mixture thereof; charging cotton fabrics into bath; supplying constant potential difference of 5-35 V to electrodes; impregnating and holding fabric in anode part of bath at temperature of 30-40 C during 0.5-5 hours; washing fabrics with cold water; discharging fabrics from bath and squeezing.

EFFECT: simplified construction and reduced production costs, increased efficiency, and improved safety during operation of apparatus.
