METHOD FOR PREPARING FLAX ROVE TO WET SPINNING Russian patent published in 1994 - IPC

Abstract RU 2008374 C1

FIELD: light industry. SUBSTANCE: method involves processing air-dry rove with aqueous solution of sodium tripolyphosphate, concentration 0.3-0.6 g/l and prevocel, concentration 0.2-0.3 g/l at a temperature of 60-65 C for 15 min. Boiling is performed at 93-95 C for 60-120 min in a solution containing 3.8-4.4 g/l alkali, 10-18 g/l sodium sulfite, raising temperature to 93-95 C in the course of 10-20 min. EFFECT: higher efficiency. 2 tbl
