PROCEDURE FOR OBTAINING filterable viscous GOOD AND PROPER PAR ARTIFICIAL FIBER

摘要

Procedure for obtaining well filterable viscous suitable for the production of artificial fibers with more than 7% cellulose less alkaline relationship by action of carbon disulphide on alkali cellulose characterized in that the alkali cellulose obtained by impregnation with caustic soda lye without squeezing the alcalinizadora lye is prepared from a cellulose having a degree of polymerization of 250-400 and alkalinization is carried out with a caustic soda lye to 16 to 26% at temperatures above 18 ° and sulfurization is effected at 20-40 ° .
