The present invention relates to cellulose fiber containing 500 to 2000 of filaments and having homogeneous physical properties and the multi-filaments according to the present invention is characterized in that the strength and the breaking elongation of the mufti-filaments are 4 to 9 g/d and 4 to 15 %, respectively. In particular, t he present invention is characterized in that each mono-filament selected 100 strands from every three part divided from mufti-filaments has properties as following: (a) 3 t o 9 g/d in average strength, 7 to 15 % in average breaking elongation and 0.035 to 0.05 5 in by birefringence, (b) the differences of the above three parts are below 1.0 g/ d in average strength, 1.5 % in breaking elongation and 0.7 denier in denier, (c) the CV (%)(coefficient of variation) of the above three parts are below 10%, and (d ) the birefringence differences of the above three parts are below 0.004. |
