▎ 摘　　要

NOVELTY - Preparing a flame-retardant regenerated cellulose fiber involves preparing viscose spinning solution, preparing a graphene-flame retardant dispersion, mixing the graphene-flame retardant dispersion with the viscose spinning solution, and subjecting to wet spinning. USE - Method for preparing a flame-retardant regenerated cellulose fiber (claimed). ADVANTAGE - The method enables to prepare a flame-retardant regenerated cellulose fiber in a cost-effective way, which has good strength, good synergistic effect because of graphene and inorganic flame retardant, and enhanced fiber flame retardant effect, contains greatly reduced amount of inorganic flame retardants, and has excessive mechanical properties, and improved fiber quality.
