Embodiment 1

[0028] A preparation method of antibacterial far-infrared health-care acrylic fiber, which comprises the following steps:

[0029] (1) Taichi stone surface antibacterial enhancement modification. Disperse 10g of commercially available Taichi stone nano powder in 100mL deionized water, add sodium tripolyphosphate accounting for 1wt% of Tai Chi stone nano powder, stir to make it fully dispersed to form a uniform dispersion, and then stir in In the dispersion, add antibacterial enhancer trimethyl [3-(trimethoxysilyl) propyl] ammonium chloride 0.5g dropwise, then add dilute nitric acid or acetic acid or phosphoric acid, after adjusting the pH to be 4, at 60 Continue to react for 12 hours under the condition of ℃, trimethyl[3-(trimethoxysilyl)propyl]ammonium chloride contains cationic antibacterial groups, and the antibacterial performance is stable, and the silicon-oxygen-carbon bonds in its molecules are easy to dissolve in water. Hydrolysis reacts with hydroxyl groups on the su...

Embodiment 2

[0032] A preparation method of antibacterial far-infrared health-care acrylic fiber, which comprises the following steps:

[0033] (1) Taichi stone surface antibacterial enhancement modification. After fully drying 15g of commercially available Taichistone nanopowder to remove surface moisture, disperse it in 100mL of deionized water. Sufficient drying facilitates rapid dispersion of Taichistone nanopowder in an aqueous solution with a dispersant. Add Zhan Taichistone nanopowder 3wt% sodium hexametaphosphate, stirring to make it fully dispersed to form a uniform dispersion, and then adding the antibacterial enhancer trimethyl[3-(trimethoxysilyl) propane to the dispersion while stirring. Base] ammonium chloride 0.8g, then add dilute nitric acid or acetic acid or phosphoric acid dropwise, after adjusting the pH to 6, continue the reaction at 75°C for 16 hours, trimethyl[3-(trimethoxysilyl)propyl ] Ammonium chloride contains cationic antibacterial groups, and its antibacterial per...

Embodiment 3

[0036] A preparation method of antibacterial far-infrared health-care acrylic fiber, which comprises the following steps:

[0037] (1) Taichi stone surface antibacterial enhancement modification. After fully drying 20g of commercially available Taichi Stone nanopowder to remove surface moisture, disperse it in 100mL of deionized water, add sodium pyrophosphate accounting for 5wt% of Taichistone nanopowder, and stir to make it fully dispersed to form a uniform dispersion. Then, in the dispersion liquid, drip antibacterial enhancer trimethyl [3-(trimethoxysilyl) propyl] ammonium chloride 1.2g while stirring, then add dilute nitric acid or acetic acid or phosphoric acid dropwise, adjust the pH After it is 7, the reaction is continued for 24 hours at 80°C. Trimethyl[3-(trimethoxysilyl)propyl]ammonium chloride contains cationic antibacterial groups, and its antibacterial performance is stable. The silicon in its molecule Oxygen-carbon bonds are easily hydrolyzed in water and react...

Abstract

The invention relates to an antibacterial far infrared health care acrylic fiber and a preparation method and application thereof. The method comprises the following steps: firstly performing surfaceantibacterial reinforcement and modification on Tai chi stone nano-powder by adopting a non-polar dispersant and and antibacterial reinforcing agent, trimethyl [3-(triethoxy silicyl) propyl] ammoniumchloride, then forming a dispersion solution from the modified Tai chi stone nano-powder and an amidogen coupling agent as well as deionized water, soaking acrylic fiber in the dispersion solution according to a certain bath ratio and reaction conditions, and after reaction is ended, firstly flushing and washing with a large amount of organic solvent deionized water, and then airing in a natural condition, so as to obtain the antibacterial far infrared health care acrylic fiber. The fiber can be applied to fabrics of underwear, briefs, sock, sport suit, swimsuit, sun-proof clothing and home textile, and is remarkable and lasting in antibacterial and far infrared efficacies, with the far infrared emissivity reaching more than 93%, and the overall antibacterial property reaching more than 94.2%.

Description

technical field [0001] The invention belongs to the field of fiber processing, and in particular relates to an antibacterial far-infrared health-care acrylic 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 texti...
