[0021] Example 1:
[0022] A preparation method of high water absorption and antibacterial blended cotton gauze includes the following steps:
[0023] (1) Carry out swelling treatment on cotton gauze, the cotton gauze is made by blending seaweed fiber and cotton fiber, the weight ratio of seaweed fiber and cotton fiber is 1:2; the swelling treatment includes 20wt.% hydrogen Sodium oxide solution is a swelling agent, and the cotton gauze is soaked in the swelling agent for 10 minutes at 26°C.
[0024] (2) Carry out carboxymethylation modification treatment on the cotton gauze after swelling treatment, the carboxymethylation rate is 5%.
[0025] (3) Use 37℃ warm water to wash cotton gauze;
[0026] (4) Use 1wt.% dilute hydrochloric acid to pickle cotton gauze to neutralize residual caustic soda;
[0027] (5) Wash the cotton gauze with cold water for many times until the pH of the cotton gauze is neutral;
[0028] (6) Put the cotton gauze treated in step (5) soaked in absolute ethanol for 5...
