Title:
REGENERATED CELLULOSE FIBER AND PRODUCTION THEREOF
Document Type and Number:
Japanese Patent JP3852631
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain the subject fiber having a good dyeability and an excellent touch feeling and excellent in resource saving property and environmental adoptability by performing a dry and wet type spinning of a spinning stock solution obtained by dissolving a specific cellulose by using N methylmorpholine-N-oxide as a solvent.
SOLUTION: This method for producing a regenerated cellulose fiber is to use a stock solution obtained by dissolving 10-25 wt.% cellulose by using N-methylmorphorine-N-oxide as a solvent so as to use ≤450 mean degree of polymerization of the cellulose, 5-20 wt.% of which is the cellulose having ≥500 mean degree of polymerization and contain 1-10 wt.% lignin based on the total weight of the cellulose for obtaining an objective fiber.
