Title:
MANUFACTURE OF REGENERATED CELLULOSE PRODUCT
Document Type and Number:
Japanese Patent JPS564601
Kind Code:
A
Abstract:
A process for the preparation of regenerated cellulose shaped bodies from spinning dopes comprising solutions of methylol derivatives of cellulose in organic solvent selected from dimethylformamide, dimethylacetamide, dimethylsulphoxide and N-methyl-pyrrolidone is described. The cellulose derivative is coagulated from the spinning dope in a coagulating bath, the main component of which is a high-boiling alcohol capable of reacting with the free (para)formaldehyde and with the bound (para)formaldehyde of the methylol derivative to a degree varying with the temperature. It is possible to prepare filaments and yarns having excellent characteristics by starting from solutions having high CH2O and cellulose concentrations and high MS ratios.
