The lingnocellulose was pre-treated by alkaline-peroxide treatment with 12% hydrogen peroxide solution. The holocellulose was prepared by Wise method, and the pure cellulose was obtained from the obtained holocellulose by 5% KOH treatment. Lignocellulose nanofibril (LCNF), holocellulose nanofibril (HCNF), and pure cellulose nanofibril (PCNF) were prepared by wet-disk milling and high-pressure homogenizing from the lignocellulose, holocellulose, and pure cellulose. Filament fibers were obtained by wet-spinning with the 3.5wt% CNF suspensions with different chemical composition. The CNF suspensions were wet-spun in tert-butanol and acetone at 5, 10, and 20 ml/min of spinning rate though the needle of 0.2, 0.3mm. The defibrillation efficiency was improved when the lignin and hemicellulose was removed, and smaller fibers with diameters in the order of PCNF > HCNF > LCNF were produced. The diameter of wet-spun fibers were in the range of 200-300 ㎛. The tensile strength of the wet-spun fibers was higher in order of HCNF > PCNF > LCNF. In all samples, the tensile strength was increased as the spinning rate was increased from 10 ml/min to 30 ml/min. The Orientation index was approximately 0.62.
