[0053] The present invention also provides a method for preparing an antibacterial and antipruritic catalytic fiber based on metal phthalocyanine, comprising:
[0054] Refluxing the modified cellulose fiber containing mercapto group in the metal phthalocyanine solution to obtain the modified cellulose fiber loaded with metal phthalocyanine;
[0055] The modified cellulose fiber loaded with metal phthalocyanine in NaIO 4 After treatment in the solution, the cross-linking reaction was performed in the glucose oxidase solution, and the obtained reaction product was prepared in NaBH 4 After being treated in the solution, the antibacterial and antipruritic catalytic fiber is obtained.
[0056] In the present invention, the modified cellulose fibers and metal phthalocyanines containing mercapto groups can be referred to above, and the present invention will not be repeated here.
[0057] see figure 1 , figure 1 It is a schematic diagram of the preparation process of the antibact...
Embodiment 1
[0063] Weigh 7.5g of viscose fiber, add it to 300mL of 0.3mol / L carboxyethanethiol N,N-dimethylformamide solution, ultrasonically disperse for 0.5 hours, add 0.8g of DCC, put it into a constant temperature oscillator (Set the initial temperature to 30°C, then heat up) Rotate, oscillate and stir. After 15 hours, take out the fiber, dry it at 80°C, put it into a 0.2mmol / L tetrahydrofuran solution of cobalt phthalocyanine at 70°C and reflux for 8 hours, take out the cellulose fiber loaded with cobalt phthalocyanine after the reaction is completed, Use the reaction solvent to wash repeatedly until the washing solution is colorless, then wash with ethanol and water three times respectively, and dry at 80°C to obtain cellulose-based biomimetic catalytic fibers with high catalytic activity. The catalytic activity of the cellulose-based biomimetic catalytic fiber prepared by this method is dozens of times higher than that of the direct bonded phthalocyanine on the carbon fiber.

Embodiment 2
[0066] Weigh 12g of viscose fiber, add it to 300mL of 0.3mol / L carboxypropanethiol N,N-dimethylformamide solution, ultrasonically disperse for 0.5 hours, add 1g of DCC, put it into a constant temperature oscillator (setting The initial temperature is 30°C, and the temperature rises) and stirs with rotation and vibration. After 12 hours, the fiber was taken out, dried at 90°C, put into a 0.2mmol / L zinc phthalocyanine tetrahydrofuran solution at 75°C, and refluxed for 9 hours. After the reaction was completed, the cellulose fiber loaded with zinc phthalocyanine was taken out. Use the reaction solvent to wash repeatedly until the washing solution is colorless, then wash with ethanol and water three times respectively, and dry at 80°C to obtain cellulose-based biomimetic catalytic fibers with high catalytic activity. The catalytic activity of the cellulose-based biomimetic catalytic fiber prepared by this method is dozens of times higher than that of the direct bonded phthalocyani...
