Embodiment 1
[0014] The preparation method of the present embodiment using rice straw as a raw material to prepare natural cellulose fibers comprises the following steps in sequence:
[0015] (1) Pretreatment: Mix rice straw and water at a mass ratio of 1:20, and treat for 2 hours at a temperature of 70°C;
[0016] (2) Mechanical rolling: mechanically rolling the pretreated rice straw twice, and washing with water after rolling;
[0017] (3) Alkali treatment: put the washed rice straw into a sodium hydroxide solution with a mass concentration of 10g / L, and treat it at a temperature of 80°C for 2 hours to obtain rice straw fibers, which are then taken out and washed with water ;
[0018] (4) Hydrogen peroxide treatment: put the alkali-treated rice straw fiber into 2g / L hydrogen peroxide solution, treat it at 50°C for 10 minutes, then take out the rice straw fiber and wash it with water;
[0019] (5) Softening treatment: weigh rice straw fiber and cellulose softener with a mass concentrati...
Embodiment 2
[0023] The preparation method of the present embodiment using rice straw as a raw material to prepare natural cellulose fibers comprises the following steps in sequence:
[0024] (1) Pretreatment: Mix rice straw and water at a mass ratio of 1:30, and treat for 1 hour at a temperature of 80°C;
[0025] (2) Mechanical rolling: the pretreated rice straw is mechanically rolled 3 times, and washed with water after rolling;
[0026] (3) Alkali treatment: put the washed rice straw into a sodium hydroxide solution with a mass concentration of 20g / L, and treat it for 2 hours at a temperature of 100°C to obtain rice straw fibers, which are then taken out and washed with water ;
[0027] (4) Hydrogen peroxide treatment: Put the alkali-treated rice straw fiber into 6g / L hydrogen peroxide solution, treat it at 60°C for 5 minutes, then take out the rice straw fiber and wash it with water;
[0028] (5) Softening treatment: weigh rice straw fiber and cellulose softener with a mass concentra...
Embodiment 3
[0032] The preparation method of the present embodiment using rice straw as a raw material to prepare natural cellulose fibers comprises the following steps in sequence:
