NOVELTY - Regenerated cellulose fibers comprises graphene structure, and elements other than oxygen and carbon such as iron, silicon and aluminum. The amount of elements other than oxygen and carbon is (0.03-1 wt.%). USE - Regenerated cellulose fibers for preparing civilian clothing, textile fabric, ultra-violet protective fabric or special protective clothing (claimed). ADVANTAGE - The regenerated cellulose fibers has high and far infrared effect and bacteriostat effect. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method for preparing composite containing the carbon nanostructure, which involves treating biomass carbon source with catalyst to obtain a precursor; insulating the precursor under the protective gas at 140-180 degrees C for 1.5-2.5 hours to obtain a first intermediate; raising the temperature of first intermediate to 350-450 degrees C for 3-4 hours to obtain a second intermediate; heating the second intermediate to 1100-1300 degrees C for 2-4 hours to obtain a third intermediate; and washing the third intermediate with caustic soda and acid to obtain a complex, where the heating rate is 14-18 degrees C per minute; and (2) a method for preparing regenerated cellulose fibers, which involves impregnating pulp, squeezing, crushing, aging, yellowing, dissolution, aging, filtering and degassing, where the graphene structure, and elements other than oxygen and carbon are introduced after degassing.
