The invention discloses a preparation method of carbon black and bamboo pulp composite fibers, which comprises the following steps: weighing bamboo pulp, dispersing in water, adding a sodium hypochlorite solution to perform polymerization reduction on the bamboo pulp, squeezing after polymerization reduction is completed, adding hydrochloric acid and sodium hexametaphosphate to remove ash and iron, squeezing and cleaning after ash and iron are removed, adding enzyme to treat cellulose after cleaning is completed, squeezing after enzymolysis, and performing alkaline leaching to obtain the carbon black and bamboo pulp composite fibers. Squeezing after alkaline leaching, and aging to obtain bamboo alkali fibers; adding cellulose into the alkali/urea/ZnO aqueous solution, fully mixing, freezing, and stirring and grinding to prepare a cellulose solution; adding the carbon black powder into an alkali/urea/ZnO solvent, and stirring and dissolving to obtain a carbon black solution; mixing the cellulose solution and t
