NOVELTY - Method for preparing a nanocarbon black modified viscose fiber, involves (a) adding 0.01 part mass sodium hydroxide to 25 parts mass aqueous dispersion of graphene oxide having concentration of 2 mg/g, mixing and stirring to obtain mixed solution, (b) mixing low dibutyl phthalate value nano-carbon black and high dibutyl phthalate value nano-carbon black in a mass ratio of 3-5:1 to obtain mixed nano-carbon black, and adding 0.12-0.2 part mass mixed nano-carbon black to obtained mixed solution, and stirring at 100 degrees C for 1 hour to obtain mixed dispersion, where the dibutyl phthalate value of the high dibutyl phthalate value nano-carbon black is 360-400, and the dibutyl phthalate value of low dibutyl phthalate value nano-carbon black is 200-280, and (c) adding 100 parts mass viscose spinning solution having 9-12 wt.% nail fiber to the mixed dispersion, and uniformly mixing, forming, holding, washing, desulfurizing, oiling, spinning in a coagulation bath by spinneret, drying and packing. USE - The method is used for preparing nanocarbon black modified viscose fiber. ADVANTAGE - The method maintains excellent dispersion, anti-static function, anti-UV effect and anti-bacterial property, has stable function and does not decay with water washing.
