[0020] Example 1
[0021] The method for preparing an antibacterial webbing based on in-situ disclosed in the present invention includes the following steps:
[0022] a. Put the cotton fiber in a sodium periodate solution with a concentration of 0.1g / L to prevent light and oxidize for 200 minutes, at a reaction temperature of 80°C, and a bath ratio of 1:50 to obtain oxidized cotton fiber;
[0023] b. Immerse the oxidized cotton fiber in a polyacetimide solution with a concentration of 6g / L at a reaction temperature of 60°C and a bath ratio of 1:50 to obtain a polyacetimide grafted cotton fiber;
[0024] c. The polyacetimide grafted cotton fiber obtained after the step is immersed in a silver nitrate aqueous solution with a concentration of 0.15 mol / L at a bath ratio of 1:60, and reacted at 35°C for 14 hours. The silver nano-particle load is formed, washed with deionized water and absolute ethanol three times in sequence, and dried in vacuum at 40°C for 6 hours to obtain antibacterial ...

[0030] The method for preparing an antibacterial webbing based on in-situ disclosed in the present invention includes the following steps:
[0031] a. Put the cotton fiber in a sodium periodate solution with a concentration of 8g / L to prevent light and oxidize for 300 minutes, the reaction temperature is 100℃, and the bath ratio is 1:50 to obtain oxidized cotton fiber;
[0032] b. Immerse the oxidized cotton fiber in a polyacetimide solution with a concentration of 2g / L at a reaction temperature of 90°C and a bath ratio of 1:50 to obtain a polyacetimide grafted cotton fiber;
[0033] c. The polyacetimide grafted cotton fiber obtained after the step is immersed in a silver nitrate aqueous solution with a concentration of 0.05-0.25 mol / L at a bath ratio of 1:60, and reacted at 20°C for 20 hours. The surface of the fiber is loaded with silver nanoparticles, and it is washed three times with deionized water and absolute ethanol, and dried in vacuum at 40°C for 9 hours t...

[0039] The method for preparing an antibacterial webbing based on in-situ disclosed in the present invention includes the following steps:
[0040] a. Put the cotton fiber in a sodium periodate solution with a concentration of 10g / L for 60 minutes to avoid light and oxidize the fiber at a temperature of 30°C and a bath ratio of 1:50 to obtain oxidized cotton fiber;
[0041] b. Immerse the oxidized cotton fiber in a polyacetimide solution with a concentration of 1g / L at a reaction temperature of 30°C and a bath ratio of 1:50 to obtain a polyacetimide grafted cotton fiber;
[0042] c. The polyacetimide grafted cotton fiber obtained after the step treatment is immersed in a silver nitrate aqueous solution with a concentration of 0.05 mol / L at a bath ratio of 1:60, and reacted at 25°C for 3 hours. The silver nano-particle load is formed, washed with deionized water and absolute ethanol three times in sequence, and dried in vacuum at 40°C for 6 hours to obtain antibacter...
