▎ 摘　　要

NOVELTY - Preparing white graphene regenerated cellulose composite fiber comprises (1) preparing an ethanol solution, adding dopamine, stirring, and adding white graphene to solution, ultrasonically dispersing, filtering and drying to obtain modified white graphene powder, (2) adding obtained modified white graphene powder to de-ionized water, adding a surfactant and an alkaline reagent, and performing sonication to obtain an aqueous solution of modified white graphene, (3) processing regenerated cellulose pulp: mixing regenerated cellulose pulp it with sodium hydroxide solution, and stirring with a mixer to make it completely mixed, placing into press to squeeze, aging pulp for treatment, and is yellowed, and (4) heating obtained solution, and mixing with obtained treated regenerated cellulose pulp, stirring uniformly by a mixer, and obtained white graphene regenerated cellulose fiber pulp is spun to prepare white graphene regenerated cellulose composite fiber. USE - The method is useful for preparing white graphene regenerated cellulose composite fiber. ADVANTAGE - The composite fiber: has good dispersion in subsequent production process, antibacterial, far-infrared, anti-ultraviolet and other functions. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for white graphene regenerated cellulose composite fiber.
