PROCEDURE FOR MANUFACTURING CELLULOSE CARBAMATE FIBRES OF FILMS

摘要

The production of cellulose carbamate fibers or films by reacting cellulose with urea to form cellulose carbamate which is dissolved in alkaline solution to form a spinning solution which is spun through an acid precipitation bath is improved by subjecting the cellulose carbamate prior to dissolution in alkaline solution to irradiation of about 0.05-10 Mrad. After dissolution in alkaline solution the same may be subjected to further mild irradiation.
