Effect of precipitation bath composition on the swelling of viscose textile yarn

Conclusions The dependence of the degree of swelling of freshly spun viscose textile yarn (primary swelling) and of the finished yarn (secondary swelling) on precipitation bath composition has been investigated by the mathematical planning method, using a three-factor experiment.The optimum precipitation bath composition has been found, which ensures a minimum degree of swelling of viscose textile yarn and, consequently, a more uniform distribution of yarn properties over the cake layers, which has made it possible to increase cake weight.Translated from Khimicheskie Volokna, No. 4, pp. 26–28, July–August, 1985.
