NOVELTY - Preparing regenerated cellulose fiber coated with graphene oxide comprises (i) adding sodium hydroxide, urea and dried regenerated cellulose into the water, and stirring at -15 degrees C to 0 degrees C until completely dispersed in an ice salt bath, (ii) adding the spherical graphene oxide powder into the dispersion prepared in the step (i), stirring at -15 degrees C to 0 degrees C in an ice salt bath, where the initial rate is 50-100 revolutions per minute, stirring for a certain period of time, and adjusting the stirring rate to 300-400 revolutions per minute to obtain composite coating liquid, (iii) spraying the spinning solution prepared in the step (i) through the injector from the porous spinning into the coagulation bath, then stretching through a multi-stage water bath, applying the composite coating liquid prepared in the step (ii) to the surface of the fiber, then carrying out high temperature steam drawing at 150-200 degrees C, the draw ratio is 1.2, and receiving the wire on the reel to obtain final product. USE - The method is useful for preparing regenerated cellulose fiber coated with graphene oxide. ADVANTAGE - The regenerated cellulose fiber has excellent antistatic property, mechanical property, sterilization, and anti-ultraviolet and far infrared performance. DETAILED DESCRIPTION - Preparing regenerated cellulose fiber coated with graphene oxide comprises (i) adding sodium hydroxide, urea and dried regenerated cellulose into the water, where the mass ratio between sodium hydroxide, urea, dried regenerated cellulose and water is 7.5-10:10-15:1-10:100, and stirring at -15 degrees C to 0 degrees C until completely dispersed in an ice salt bath, (ii) adding the spherical graphene oxide powder into the dispersion prepared in the step (i), stirring at -15 degrees C to 0 degrees C in an ice salt bath, where the initial rate is 50-100 revolutions per minute, stirring for a certain period of time, and adjusting the stirring rate to 300-400 revolutions per minute to obtain composite coating liquid, (iii) spraying the spinning solution prepared in the step (i) through the injector from the porous spinning into the coagulation bath, then stretching through a multi-stage water bath, applying the composite coating liquid prepared in the step (ii) to the surface of the fiber, then carrying out high temperature steam drawing at 150-200 degrees C, the draw ratio is 1.2, and receiving the wire on the reel to obtain final product, where the first stage water bath temperature is 50 degrees C, the draw ratio is 2.1; the second stage water bath temperature is 90 degrees C, the draft ratio is 1.6; and the third stage water bath temperature is 100 degrees C, and the draft ratio is 1.4.
