Example Embodiment

[0020] Embodiment 1.
[0021] A production process of nano-silver negative ion functional home textile fabric, comprising the following steps:
[0022] Step 1. Preparation of nano-silver particles:
[0023] The zeolite powder is soaked in a silver nitrate solution with a mass fraction of 20%, the mass ratio of the zeolite powder to the silver nitrate solution is 1:10, and microwave oscillation is performed for 20 hours, so that the silver ions in the solution are fully adsorbed in the voids of the zeolite particles;
[0024] The above solution with a mass ratio of 1:1 is mixed with an aqueous solution of the surface aid polyvinylpyrrolidone with a mass fraction of 5%, and the resulting mixed solution is added to the reactor, and then 20 times of deionized water is added; stirring, Add 1% hydrazine hydrate solution dropwise with a metering pump, stop adding hydrazine hydrate when the pH of the mixture reaches 7.0, and continue stirring for half an hour to reduce silver ions to silver element;
[0025] The reacted liquid was taken out, left standing for 3 days, fully settled and decantly filtered, the precipitate was washed with deionized water 5 times, and the filtrate was decanted to circulate precipitation and washing;
[0026] The accumulated precipitate is dried at 80° C. to remove moisture, and ball-milled to obtain nano-silver particles with zeolite as a carrier, wherein the nano-silver particle size is 15 nanometers and the content is 20%;
[0027] Step 2, the preparation of tourmaline particles:
[0028] First, the tourmaline is crushed to less than 1 micron, and then the ultrafine mill equipment is used for grinding. The grinding medium adopts alumina balls with a ball diameter of 2.0 mm, and the dispersing agent uses sodium hexametaphosphate with a solution concentration of 20% to obtain nanometers. grade tourmaline particles;
[0029] Step 3. Preparation of nanocapsules:
[0030] Make nano-spandex wrap nano-silver particles and tourmaline particles to prepare nano-capsules;
[0031] Step 4. Fabric production:
[0032] Apply the nanocapsules as the surface coating of the fabric; immerse the coated fabric in the saturated nano spandex solution for shaping, then dry and dry, so that the nano silver particles and the tourmaline particles are tightly bonded on the surface of the fabric , to complete the preparation of the fabric.
[0033] It has been verified that the bacteriostatic rate of the fabric in Example 1 is 99%, and the bacteriostatic rate is still more than 90% after 30 times of washing, reaching the FZ/T73023-2006 AAA level standard; the negative ion release under the static condition of the fabric is not less than 7000/ Square centimeter, there are still 3000 pieces/square centimeter after washing 30 times.
[0034] The invention can endow the product with strong antibacterial and negative ion functions, thereby effectively resisting the invasion of various bacteria to the human body without drug resistance, and at the same time improving the air quality in the home environment, promoting human metabolism, improving physical fitness and other multiple health care effects.
