Embodiment 1

[0018] The preparation method of the skin-core structure antibacterial polyester involved in the present embodiment comprises the following steps:

[0019] (1) Coating treatment of silver powder: Use trihydroxyethylmethyl quaternary ammonium methyl sulfate and silver powder to mix and stir to eliminate the electrostatic force between silver powder The weight ratio is 0.5:100, and the silver powder particle size is 3-20 μm; mix ethyl orthosilicate with deionized water and ethanol according to the weight ratio of 1:1.5:4, add hydrochloric acid solution to adjust the pH to 3, and At 20°C, react for 45 minutes to obtain a transparent silica sol; add the mixed silver powder into the silica sol for stirring, and when a uniform suspension is formed, add concentrated ammonia water with a mass fraction of 28% until stirring forms gel state, and then washed with deionized water; finally put the obtained gel into a vacuum drying oven for drying treatment, that is, the surface-coated SiO ...

Embodiment 2

[0023] The preparation method of the skin-core structure antibacterial polyester involved in the present embodiment comprises the following steps:

[0024] (1) Coating treatment of silver powder: Use trihydroxyethylmethyl quaternary ammonium methyl sulfate and silver powder to mix and stir to eliminate the electrostatic force between silver powder The weight ratio is 2:100, and the silver powder particle size is 3-20 μm; mix ethyl orthosilicate with deionized water and ethanol according to the weight ratio of 1:2.5:7, add hydrochloric acid solution to adjust the pH to 6, and At 35°C, react for 10 minutes to obtain a transparent silica sol; add the mixed silver powder into the silica sol for stirring, and when a uniform suspension is formed, add concentrated ammonia water with a mass fraction of 28% until stirring forms gel state, and then washed with deionized water; finally put the obtained gel into a vacuum drying oven for drying treatment, that is, the surface-coated SiO 2...

Abstract

The invention belongs to the technical field of chemical fiber processing, and particularly relates to a preparation method of an antibacterial polyester fiber in core-spun structure. The preparationmethod includes (1), subjecting silver powder to a coating treatment to obtain the silver powder of which the surface is coated with SiO2 and having the grain size being 3 to 20 micrometers; (2), preparation of master batch of the antibacterial polyester fiber, to be specific, melting the coated silver powder and polyester chips, granulating to obtain the antibacterial polyester fiber mixed with the coated silver powder through a granulator; (3), supplying materials to core-spun spinneret assemblies through two screw extruding machines, taking polyester fiber as the core while the antibacterial polyester fiber master batch mixed with coated silver powder as the covering, spinning and finishing to obtain the antibacterial polyester fiber in core-spun structure. Since the silver powder is coated, aggregation of the silver powder is reduced, the obtained polyester fiber has better antibacterial performance, and the silver powder in the fiber is not easy to come off; since the fiber is ofthe core-spun structure, the antibacterial effect is guaranteed while the material cost is lowered.

Description

Technical field: [0001] The invention belongs to the technical field of chemical fiber processing, and in particular relates to a method for preparing antibacterial polyester with a skin-core structure. The polyester fiber with antibacterial function is prepared by utilizing the sterilizing properties of silver ions. Background technique: [0002] As one of the three main fibers in synthetic fibers, polyester has been widely used in textile and apparel fabrics and other fields because of its excellent physical and chemical properties. With the development of society and the improvement of people's living standards, traditional textile and clothing can no longer meet people's requirements for daily wear. Therefore, functional textile garments have emerged as the times require in recent years. Wearing textiles with antibacterial function can make people's travel and activities safer, and people are paying more and more attention to the antibacterial performance of clothing. ...
