Abstract

Cellulose(cell)/dimethylacetamide(DMAc)/lithium chloride(LiCl) solutions were prepared and spun to fibers in coagulants. Then, obtained fibers were annealed in appropriate chemicals. The fibers from cell/DMAc/LiCl showed cell III morophology prior to annealing without differenciating the kind of coagulants. Morphology of crystallite, however, was affected by annealing. Annealed fibers at 17$0^{\circ}C$ showed cell IV morphology and had better mechanical properties than others.
