Embodiment 1
[0037] S1. Cut the dried camellia husk into small pieces, add it to the mixed solution of NaOH and Na2SO3, heat it to 85°C for 90 minutes to obtain helicocellulose; the mass fraction of NaOH and Na2SO3 in the mixed solution is 4wt%, and the mixed solution The mass ratio of NaOH to Na2SO3 is 10:1.
[0038] S2. Add the hemcellulose obtained in step S1 into the KOH solution, heat to 70° C. for 90 minutes to react to obtain cellulose; the mass fraction of the KOH solution is 15 wt%, and the mass ratio of hemcellulose to KOH is 15:1.
[0039] S3. Disperse the cellulose obtained in step S2 into distilled water, add an appropriate amount of H2O2 solution dropwise for bleaching, and obtain bleached cellulose; the H2O2 solution mass concentration is 30wt%, and the mass ratio of cellulose to H2O2 is 5:1. The time is 90min, and the bleaching temperature is 65°C.
