Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art, aiming at the fact that the textile fiber nano-silver doped with nano-silver in the prior art is easy to fall off, endangers health and the environment, the antibacterial performance is not durable, and the silver particles are easy to agglomerate and cause the antibacterial effect to decline. Disadvantages, under the premise of mass production and manufacturing, design and seek a preparation method for antibacterial polyester staple fibers, so that polyester staple fibers have antibacterial properties and antibacterial durability

Embodiment 1

[0016] The preparation method of the antibacterial polyester staple fiber that present embodiment relates to, comprises the following steps:

[0017] (1) Treatment of silver powder: Mix and stir sodium nonylphenoxypropane sulfonate powder with silver powder to reduce the electrostatic force between silver powders. The weight ratio of sodium nonylphenoxypropane sulfonate to silver powder is 1:100 , the particle size of silver powder is 3-20μm; mix ethyl orthosilicate with deionized water and ethanol according to the weight ratio of 1:1:5, add hydrochloric acid to adjust the pH value of the solution to 3, and react at a temperature of 15°C for 50min , to obtain a transparent silica sol; add the mixed silver powder into the silica sol and stir, and when a uniform suspension is formed, add concentrated ammonia water with a mass fraction of 28% until stirring to form a gel state, and then use Ionized water cleaning; finally put the obtained gel into a vacuum drying oven for drying ...

Embodiment 2

[0021] The preparation method of the antibacterial polyester staple fiber that present embodiment relates to, comprises the following steps:

[0022] (1) Treatment of silver powder: Mix and stir sodium nonylphenoxypropane sulfonate powder with silver powder to reduce the electrostatic force between silver powders. The weight ratio of sodium nonylphenoxypropane sulfonate to silver powder is 8:100 , the particle size of silver powder is 3-20 μm; mix ethyl orthosilicate with deionized water and ethanol according to the weight ratio of 1:3:6, add hydrochloric acid to adjust the pH value of the solution to 5, and react for 15 minutes at a temperature of 40°C , to obtain a transparent silica sol; add the mixed silver powder into the silica sol and stir, and when a uniform suspension is formed, add concentrated ammonia water with a mass fraction of 28% until stirring to form a gel state, and then use Ionized water cleaning; finally put the obtained gel into a vacuum drying oven for d...

Abstract

The invention belongs to the technical field of processing of chemical fibers, and particularly relates to a preparation method of antibacterial polyester staple fibers. The preparation method comprises the following steps: (1) carrying out coating treatment on silver powder, wherein the particle size of the used silver powder is 3-20 mu m, so that the silver powder coated with SiO2 on the surfaceis obtained; (2) preparation of antibacterial polyester masterbatches: melting the coated silver powder and polyester slices, and cutting into antibacterial polyester masterbatches doped with the coated silver powder through a granulator; and (3) spinning process: preparing the antibacterial polyester staple fibers by melt conveying, spinning, side blowing, bundling, stretching, tensioning and heat setting, crimping, relaxation and shaping, cutting and packaging. By coating treatment of the used silver powder, agglomeration of the silver powder is relieved, the antibacterial effect of the produced polyester staple fibers is good, and the silver powder in the fibers is not easy to fall off.

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 staple fibers, which utilizes the bactericidal properties of silver ions to prepare polyester staple fibers with antibacterial functions. Background technique: [0002] Polyester staple fiber is a fiber obtained by spinning polyester (polyethylene terephthalate, PET for short) into tow and cutting it. Polyester staple fiber has a very wide range of applications, and its strength is nearly twice as high as that of cotton. , 3 times higher than wool, can be spun alone or blended with cotton, viscose fiber, hemp, wool, etc. The obtained yarn is mainly used for clothing weaving, and can also be used for home decoration fabrics, filling materials and thermal insulation materials, with softness , uniform thickness without knots, acid and alkali resistance and other functions. With the improvement of people's...
