[0053] The second aspect of the present invention provides the preparation method of antibacterial functionalized fiber, and described preparation method comprises the steps:
[0054] A: Dissolve the hydrophilic polymer material in water at 90-98°C for 3-6 hours, then add nano-silver particles and nano-silver particle protective agent, stir for 30-60 minutes, filter and defoam to obtain component A for spinning stock solution;
[0055] B: Dissolve the organic fiber-forming high molecular polymer in dimethyl sulfoxide, add dispersant and filler and stir for 30 minutes, filter and defoam to obtain component B spinning stock solution;
[0056] C: Put the spinning stock solution of component A into the inner cylinder of the sleeve storage bin, and put the spinning stock solution of component B into the outer cylinder of the sleeve storage bin, meter the metering pump, and then use it at the same speed to pass through the sleeve infusion tube Transport to the double-ring sleeve-sh...
