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...

Description

technical field [0001] The invention relates to the technical field of textile processing, in particular to a preparation method of antibacterial polyester fibers. Background technique [0002] Polyester fiber is an important variety of synthetic fibers. It is a fiber made of PET polyester by spinning and post-processing; the fabric woven from polyester fiber filament has good strength, good elasticity, not easy to deform, corrosion resistance, etc. Excellent performance such as insulation, smoothness and stiffness, easy washing and quick drying, etc., are deeply loved by people. Polyester has a wide range of uses and is widely used in the manufacture of clothing and industrial products. [0003] However, polyester fiber fabrics also have disadvantages such as hard hand feeling, poor touch, not soft luster, poor air permeability and hygroscopicity. On the one hand, the accumulation of sweat and oil stains can easily accumulate dust and become dirty and airtight, leading to...
