초록

Dissolution of cellulose in N,N - dimethylacetamide(DMAA)/LiCl was investigated in view of solution propertied of cellulose and mechanical properties of cellulose fiber spun from those solutions. DMAA/LiCl solvent system showed the most powerful salvation on cellulose at which 9% (by weight) LiCl was contained in DMAA/LiCl. The cellulose solution showed optical anisotropy at 7.9-9.9% cellulose concentration on shear. The solution showed increased viscosity upon increasing LiCl content in DMAA/LiCl. When cellulose concentration was fixed at 4% in DMAA/LiCl, the cellulose fibers spun showed the maximum tensile strength at 7% LiCl concentration.
