Embodiment 1

[0033] A preparation method of antibacterial far-infrared health-care cotton cellulose fiber, which comprises the following steps:

[0034] (1) Surface modification of Taichi stone nano-powder. Disperse 1g of commercially available Taichi stone nanopowder in a mixed solvent of 120mL deionized water and toluene, and add 0.05g of poloxamer 188, stir to fully disperse, and then dropwise add 0.1% of the volume fraction of the mixed solution γ-methacryloyloxypropyltrimethoxysilane was stirred and mixed, and reacted at room temperature for 12 hours. After the reaction was completed, anhydrous ethanol accounting for 1 / 5 of the volume of the solution after the reaction was added as a precipitant for centrifugal purification. After purification, the final product is dried in a vacuum oven at room temperature to obtain the modified Taichi stone nanopowder. Such as figure 1 As shown, the surface of Taichi stone contains a large number of -OH functional groups. In the toluene solution, ...

Embodiment 2

[0038] A preparation method of antibacterial far-infrared health-care viscose cellulose fiber, which comprises the following steps:

[0039] (1) Surface modification of Taichi stone nano-powder. Disperse 2g of commercially available Taichistone nanopowder in a mixed solvent of 320mL deionized water and methanol, add 0.15g of poloxamer 188, stir and disperse fully, and the Taichistone nanopowder needs to be fully dried before being dispersed in the solvent Surface moisture, so that the Taichi stone nano powder can be fully dispersed in the solvent, after dispersion, add dropwise γ-methacryloxypropyltrimethoxysilane that accounts for 1% of the volume fraction of the mixed solution and stir and mix, pass Add dilute nitric acid, acetic acid or phosphoric acid to adjust the pH value to 4, react at room temperature for 18 hours, add anhydrous ethanol accounting for 1 / 4 of the solution volume after the reaction as a precipitant for centrifugal purification, and centrifuge and purify ...

Embodiment 3

[0043] A preparation method of antibacterial far-infrared health-care lyocell cellulose fiber, which comprises the following steps:

[0044] (1) Surface modification of Taichi stone nano-powder. Disperse 5g of commercially available Taichi stone nanopowder in a mixed solvent of 1000mL deionized water and ethanol, add 0.5g of polyvinylpyrrolidone, stir and disperse fully, and the Taichi stone nanopowder needs to be fully dried to remove surface moisture before being dispersed in the solvent , so that the Taichi stone nano powder can be fully dispersed in the solvent, after dispersion, dropwise add oleyl alcohol phosphate with a volume fraction ratio of 2% of the mixed solution and stir and mix, and adjust the pH value by adding dilute nitric acid, acetic acid or phosphoric acid 6. React at room temperature for 24 hours. After the reaction is completed, add absolute ethanol accounting for 1 / 3 of the volume of the solution after the reaction as a precipitant for centrifugal purif...

Abstract

The invention relates to an antibacterial far infrared health care cellulose fiber as well as a preparation method and application thereof. In the method, firstly, a coupling agent is used for modification; double bonds are introduced onto the surfaces of nanometer powder molecules of taichi stones; then, nanometer cellulose fiber is treated by an ammonium ceric nitrate water solution; polymerization free radicals are triggered on cellulose fiber molecular chains; finally, the modified taichi stone nanometer powder subjected to pretreatment is dispersed into an organic solvent to obtain the modified taichi stone nanometer powder solution; the free radical triggered cellulose fiber is added into the modified taichi stone nanometer powder solution to react under a certain condition; drying is performed; the antibacterial far infrared health care cellulose fiber is prepared. The fiber can be applied to underwear, briefs, socks, shirts or home textile fabrics; the taichi stone powder is uniformly distirubted on the surface of the cellulose fiber material in a covalent bond mode; the obvious and durable anti-bacterial far infrared performance is given to the fiber; the far infrared rayemission rate reaches a value being higher than 92 percent; the general anti-bacterial performance is 93.8 percent or higher.

Description

technical field [0001] The invention belongs to the field of fiber processing, and in particular relates to an antibacterial far-infrared health-care cellulose fiber and a preparation method and application thereof. Background technique [0002] Tai Chi Stone is a natural ore whose main component is silicon dioxide, a small amount of titanium dioxide, and various trace metal mineral elements. Its high-frequency resonance frequency is quite close to the resonance frequency of human cell molecules, which can promote the body to absorb and gather positive energy. It has many excellent functions such as far-infrared radiation performance, anti-ultraviolet performance and certain antibacterial performance. [0003] According to investigations and studies, it is found that wearing underwear made of Tai Chi stone can significantly promote the microcirculation of human blood and enhance metabolism. With the discovery of the natural health function of Tai Chi Stone, a variety of tex...
