preparation example Construction

[0033] Such as figure 1 Shown, described preparation method comprises the steps:

[0034] 100. Add the fiber substrate to the first solvent and stir at the first stirring temperature for a first time to obtain a first electrospinning base solution.

[0035] The fiber substrate is the polymer base material that constitutes the antibacterial fiber. Specifically, the corresponding high molecular polymer can be selected and used according to the needs of the actual situation (such as tensile properties, warmth retention or smoothness, etc.). In some embodiments, the fiber substrate is selected from polyacrylonitrile, polylactic acid, polyethylene, polypropylene, polystyrene, polyvinyl alcohol, polyethylene oxide, polycarbonate and polyvinylidene chloride One or more to prepare antibacterial fibers with different performances.

[0036] In some embodiments, the mass percentage of the fiber substrate in the first electrospinning base solution is controlled between 5-25% to avoid i...

Embodiment 1

[0059] 1) Dissolve polyacrylonitrile in an organic solvent mixed with N,N-dimethylformamide (DMF) and acetone (the volume ratio of the two is 1:1), and stir at 50°C for 2 hours to obtain the first An electrospinning base solution.

[0060] Wherein, polyacrylonitrile accounts for 10% by mass of the solution.

[0061] 2) Add the photocatalytic material and dispersant into the acetone solvent, heat to 35°C in a water bath, and stir for 2 hours to obtain the second electrospinning base liquid.

[0062] Wherein, the photocatalytic material is a non-metallic photocatalytic material, accounting for 10% by mass; the dispersant is polyvinylpyrrolidone, accounting for 3% by mass.

[0063] 3) Add the first electrospinning base liquid and the second electrospinning base liquid in proportion, and stir for 1.5 hours to form an electrospinning liquid.

[0064] Wherein, the proportion of the first electrospinning base liquid is 55%.

[0065] 4) Set the parameters of the electrospinning pro...

Embodiment 2

[0069] 1) Dissolving polyvinyl alcohol in water and stirring at 50° C. for 2 hours to obtain the first electrospinning base solution.

[0070] Wherein, polyvinyl alcohol accounts for 20% by mass of the solution.

[0071] 2) Add the photocatalytic material and dispersant into the acetone solvent, heat to 35°C in a water bath, and stir for 1 hour to obtain the second electrospinning base liquid.

[0072] Wherein, the photocatalytic material is titanium dioxide, accounting for 15% by mass; the dispersant is silica airgel, accounting for 3% by mass.

[0073] 3) Add the first electrospinning base liquid and the second electrospinning base liquid in proportion, and stir for 1.5 hours to form an electrospinning liquid.

[0074] Wherein, the proportion of the first electrospinning base liquid is 45%.

[0075] 4) Set the parameters of the electrospinning process, and spin the electrospinning solution to prepare antibacterial fibers.

[0076] Among them, the distance between the posi...

Abstract

The invention relates to the technical field of anti-bacteria, particular to a preparation method for an antibacterial fibre. The method comprises the following steps of: adding a fibre base materialinto a first solvent, and stirring at a first stirring temperature for a first time to obtain first electrostatic spinning base liquid; simultaneously adding a photocatalytic material and a dispersantinto a second solvent, and stirring at a second stirring temperature for a second time to obtain second electrostatic spinning base liquid; stirring and mixing the first electrostatic spinning base liquid and the second electrostatic spinning base liquid to form electrostatic spinning liquid; and performing spinning on the electrostatic spinning liquid to prepare the antibacterial fibre. According to the embodiment of the invention, the preparation conditions are mild; the photocatalyst activity is excellent; the cost is low; a production process is simple and easy to control; industrial production is facilitated; and the antibacterial fibre has excellent antibacterial effect on the bacteria, such as escherichia coli and staphylococcus aureus, and is suitable for the fabrics, such as clothing and socks, decoration fabrics, such as curtains and table cloth, outdoor products, such as field tents and quick-drying clothes, and the medical products, such as medical gauze and surgical masks.

Description

technical field [0001] The invention relates to the technical field of antibacterial materials, in particular to a preparation method of antibacterial fibers. Background technique [0002] With the development of society, the public has higher and higher requirements for the quality of life. Fibrous textiles (such as towels, clothing, and rags, etc.), as indispensable items in daily life, have a very high frequency of contact and use. As a result, these fiber woven products are prone to breed bacteria and viruses, and at the same time inevitably cause adverse effects on the health of its users. [0003] People usually adopt methods such as external disinfection or cleaning fiber fabrics to solve the problem of bacterial virus growth. However, excessive disinfection or cleaning frequency will cause unnecessary troubles in daily use. [0004] In the process of realizing the present invention, the applicant found that there are many fiber preparation methods, such as electro...
