Embodiment 1
[0040] Antibacterial polyester fiber is prepared by the following method:
[0041] (1) Mix hexamethylene diisocyanate and triethylene diamine in a volume ratio of 95:5 to obtain a mixed solution. The polyester chips and the mixed solution are mixed at a solid-to-liquid ratio of 1g:8mL, soaked at 25°C for 3 hours, using 200 Filter with mesh filter cloth, mix the filter cake and deionized water at a solid-liquid ratio of 1g:8mL, soak at 25°C for 3 hours, filter, and dry the filter cake at 50°C to constant weight to obtain pretreated polyester chips;
[0042] (2) Mix 100 parts of pretreated polyester chips, 6 parts of kaolin, 6 parts of medical stone powder, 0.5 part of modified carbon nanotubes, 1 part of γ-aminopropyl triethoxysilane, and 1 part of polyethylene wax, Stir at 600 rpm for 30 minutes, and dry at 50°C for 6 hours to obtain a mixture;
[0043] (3) melting and extruding the mixture through a twin-screw extruder, spinning, winding through a spinneret to obtain primary...
