Embodiment 1
[0025] Weigh 3g of Tris and dissolve it in 150ml of water to prepare a Tris buffer solution, dissolve dopamine hydrochloride in the Tris buffer solution, the concentration of the dopamine solution is 0.2mol / L, adjust the pH value of the solution to 8.5 with hydrochloric acid, and then take 5g Put the cleaned cotton fabric into the reaction bath, control the reaction temperature to 30°C, take it out after reacting for 24 hours under the condition of magnetic stirring, clean it with distilled water, and then put it into the silver nitrate solution with a concentration of 0.3mol / L , with a bath ratio of 1:60, taken out after immersion for 8 hours, rinsed with distilled water, and dried under vacuum at 40°C. The cotton fabric with antibacterial function containing nano-silver particles can be obtained.

Embodiment 2
[0031] According to the method described in Example 1, nano silver-loaded antibacterial fabrics were prepared, the concentration of the dopamine solution was adjusted to 0.1 mol / L, the concentration of silver nitrate was adjusted to 0.1 mol / L, and other conditions were unchanged. The prepared cotton fabric containing nano-silver particles with antibacterial function has a nano-silver content of 27 mg / g. After being washed 30 times, the silver content can still reach 11 mg / g, and the bactericidal rate can reach 100%.
Embodiment 3
[0033] According to the method described in Example 1, nano silver-loaded antibacterial fabrics were prepared, and the impregnated cotton fabrics were changed to hydrophobic polyester fabrics, and other conditions were unchanged. The prepared polyester fabric containing nano-silver particles with antibacterial function has a nano-silver content of 10 mg / g. After 30 times of washing, the silver content can still reach 3 mg / g, and the bactericidal rate can reach 100%.
