Conclusions
-- The process of preparing viscose from radiation-modified cellulose using carbon disulfide in the range of 6–32% of the weight of α-cellulose in the xanthation has been investigated.
-- Equations have been given which describe the dependence of the degree of esterification of the cellulose xanthate, the ripeness index, the byproduct content, the viscosity, and the filterability of the viscoses on CS2 consumption in xanthation within the range 6–32% by wt.
-- It has been found that a decrease in consumption of CS2 primarily affects the viscosity of the viscoses obtained, and then it affects figures which characterize the content of byproducts, degree of esterification of the cellulose xanthate, ripeness, and the filterability of the spinning solutions.
