Abstract

Cellulose filaments were produced from cellulose solution of 9% LiCl/DMAc solvent using a laboratory scale wet spinning machine. The tenacities of spun cellulose fibers were increased with increasing cellulose concentration of spinning solution, draw ratio and LiCl concentration in coagulation bath, and they were decreased with increasing bath temperature. The crystalline structure of spun cellulose fiber was similar to that of viscose rayon and its crystallinity and orientation were increased with increasing draw ratio.
