Embodiment 1
[0022] (1) Preparation of Salix wood powder: Peel the Salix, crush it, pass a 100-mesh sieve, dry at 80°C, cool, and put it in a desiccator for later use;
[0023] (2) Extracting Salix cellulose: Add the Salix wood powder in step (1) to the autoclave, and add anhydrous ethanol-nitric acid mixture, where the addition amount of nitric acid is 3%wt, and the solid-liquid ratio is 1: 10. After heating to 120°C, stir for 3h, cool, filter, wash with absolute ethanol 5 times, rinse with deionized water repeatedly, and dry;
[0024] (3) Preparation of Salix Pulp: Use 10%wt NaOH to cook, bath ratio is 1:10, cooking temperature 200℃, time 3h, then 20%wt hydrogen peroxide bleaching, bleaching temperature 100℃, bleaching time 2h;
[0025] (4) Preparation of nano-composite powder-Salixo spinning solution: According to the volume ratio of 1:10, slowly add 1%wt nano-composite powder to the 10%wt salix cellulose solution, and add titanium Ester coupling agent, stirring at 80°C for 10 hours, the nan...
