REGENERATED CELLULOSIC FIBERS AND PROCESS FOR PRODUCING THE SAME

摘要

High-quality regenerated cellulosic fibers reduced in fibrillation, which is believed to be a drawback of solvent-spun regenerated cellulosic fibers, and improved in dyeability and hand is produced from a dope which is obtained by dissolving cellulose in a solvent containing N-methylmorpholine N-oxide and in which the average degree of polymerization of the cellulose is 400 or lower and 5 to 30 % by weight of the cellulose has a degree of polymerization of 500 or higher to thereby cause a liquid-crystal-like phenomenon during spinning and stretching.
