NOVELTY - Preparing regenerated cellulose composite fiber involves adding sodium hydroxide, urea, dry regenerated cellulose into water according to mass ratio of 7.5-10:10-15:1-10:100, stirring and placing in cryohydrate bath at 0-15 degrees C, mixing spherical graphene oxide powder into dispersion liquid with constant stirring under 50-100 revolutions/minute, regulating stirring speed to 300-400 revolutions/minute by continuing stirring to obtain graphene oxide, spraying spinning solution and coagulating from porous spinning by injector at 50 degrees C, where stretching ratio is 2.1 and second level water bath temperature is 90 degrees C and drafting ratio is 1.6, third-level water bath temperature is 100 degrees C, drafting ratio is 1.4, temperature of high temperature steam stretching is 150-200 degrees C, stretching ratio is 1.2 to obtain graphene oxide composite regenerated cellulose fiber. USE - Method for preparing regenerated cellulose composite fiber used in textile industry. ADVANTAGE - The method enables to prepare regenerated cellulose composite fiber has excellent mechanical property, bactericidal, anti-ultraviolet performance, good air permeability and moisture absorption property.
