Embodiment 1
[0037] A preparation method of antibacterial and anti-mite far-infrared health-care cotton cellulose fiber, which comprises the following steps:
[0038] (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 tolu...
Embodiment 2
[0043] A preparation method of antibacterial and anti-mite far-infrared health-care viscose cellulose fiber, which comprises the following steps:
[0044] (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 centrifu...
Embodiment 3
[0049] A preparation method for antibacterial and anti-mite far-infrared health-care lyocell cellulose fiber, which comprises the following steps:
[0050] (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 ce...
