The present invention relates to a cellulose fiber composed of 500 to 2,000 filaments, the strength of the multi-filament is 4 to 9 g / d, the elongation at break is 4 to 15%, characterized in that it has a uniform physical properties. More specifically, the monofilaments extracted from each part after 100 parts of the whole filaments are a) the average strength is 3 to 9 g / d, the average elongation at break is 7 to 15%, the average birefringence is 0.035 to 0.055, b) The average strength, elongation at break, and denier of the three parts are 1.0 g / d or less, 1.5% or less, and 0.7 denier or less, respectively.c) Average strength, elongation at break, and CV (%) of the denier (coefficient of variation) D) 10% or less, and d) a difference in the average birefringence value of the three parts, respectively, 0.004 or less.n n n Multifilament, Property Deviation, Cellulose Fiber, N-Methylmorpholine N-Oxide |
