Embodiment 1

[0040] The antibacterial polyester fiber is prepared by the following method:

[0041] (1) Mix hexamethylene diisocyanate and triethylenediamine at a volume ratio of 95:5 to obtain a mixed solution. Polyester chips and the mixed solution are mixed at a solid-to-liquid ratio of 1g:8mL, soaked at 25°C for 3 hours, and used 200 Filter through a mesh filter cloth, mix the filter cake and deionized water at a solid-to-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) 100 parts of pretreated polyester chips, 6 parts of kaolin, 6 parts of medical stone powder, 0.5 parts of modified carbon nanotubes, 1 part of γ-aminopropyltriethoxysilane, and 1 part of polyethylene wax are mixed, Stirring at 600 rpm for 30 minutes, drying at 50°C for 6 hours to obtain a mixture;

[0043] (3) Melt and extrude the mixed material through a twin-screw extruder, spray through a spinneret for spi...

Abstract

The invention discloses a preparation method of antibacterial polyester fiber. The method comprises the following steps that (1) a polyester chip is mixed with a mixed solution and soaked for 2-4 hours, and then filtered; the polyester chip is soaked in water for 2-4 hours, then filtered, and dried to obtain a pretreated polyester chip; (2) the above pretreated polyester chip, kaolin, medical stone powders, a carbon nanotube, gamma-aminopropyltriethoxysilane and polyethylene wax are stirred and mixed, and dried to obtain a mixture; and (3) the above mixture is fused, extruded and spun to obtain the antibacterial polyester fiber. The antibacterial polyester fiber of the invention has good antibacterial performance.

Description

technical field [0001] The invention relates to the technical field of textile processing, in particular to a preparation method of antibacterial polyester fiber. Background technique [0002] Polyester fiber is an important variety of synthetic fibers. It is made of PET polyester through spinning and post-processing; the fabric woven from polyester fiber filaments has good strength, good elasticity, not easy to deform, corrosion resistance, Excellent properties such as insulation, smoothness, 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, soft luster, poor air permeability, and poor hygroscopicity. On the one hand, the accumulation of sweat stains and oil stains can easily accumulate dust and become dirty and airtight, leading to the growth of...
