Preferably, the pillow inner and/or the pillowcase are/is woven by nano silver thread stone needle fibers.
More preferably, the preparation method of the nano silver wire stone needle fiber material comprises the following steps:
1) dissolving polyvinylpyrrolidone, iodide and stone needle powder in ethylene glycol, wherein the mass ratio of polyvinylpyrrolidone to iodide to stone needle powder is 160-260: 1: 30-50, fully stirring and dissolving to obtain a solution A;
2) dissolving silver nitrate in an ethylene glycol solution, stirring until the silver nitrate is dissolved, wherein the mass ratio of the silver nitrate to the stone needle powder is 1: 1-3, obtaining a solution B;
3) stirring and heating the solution A to 140-180 ℃, turning off the heating, and uniformly adding the solution B into the solution A;
4) after full reaction, quickly cooling to room temperature, stopping the reaction, and washing the reaction by using an organic solvent to obtain superfine nano silver wires/stone needles;
5) dissolving 30-35 parts by weight of superfine nano silver wire/stone needle in 40-60 parts by weight of polar solvent, adding 25-30 parts by weight of chitosan, magnetically stirring at room temperature for 30-60 min, and fully mixing to prepare a uniform spinning solution; the concentration of the spinning solution is 1-65 wt%;
6) and spinning the spinning solution by using an electrostatic spinning device to obtain the superfine nano silver wire/stone needle fiber material.
According to the invention, the stone needle in the traditional Chinese medical therapy is used as a material to be added into the processing process of the antibacterial material, silver is a metal simple substance with a very good antibacterial and disinfection effect, and is widely applied to the antibacterial field, and the nano silver wire has better stability than nano silver particles and can be applied to the textile field; the superfine nano silver wire/stone needle fiber capable of releasing infrared rays and resisting bacteria is prepared by adding silver nitrate, so that the conductivity of the fiber is further improved, and the prepared superfine nano silver wire/stone needle fiber has the function of releasing infrared rays.
The invention provides a preparation method of a nano silver wire stone needle fiber material, wherein the nano silver wire has a larger specific surface area, so that more sites of the nano silver wire are in contact with bacterial colonies, and the antibacterial and bacteriostatic effects can be better achieved; according to the traditional Chinese medicine, the stone needle has the effects of soothing the nerves, regulating qi and blood and dredging channels and collaterals, certain treatment and health care functions are achieved through microcrystalline infrared rays and pulses, the stone needle fiber can promote blood circulation and help sleep, and the nano silver wire/stone needle fiber antibacterial material has the double functions of antibiosis and health care by combining the microcrystalline infrared rays and the microcrystalline infrared rays; the preparation process is relatively simple and easy to operate.
Although the pillowcase and pillow core in the current market have antibacterial function, the effect is general, and the pillow can not play a good role in protecting skin. The stone needle is less applied to the textile pillow, and the nano silver wire has larger specific surface area, so that more sites are in contact with bacterial colonies, and the antibacterial and bacteriostatic effects can be better achieved; the pillow can resist bacteria, promote the blood circulation of the head in the process of wiping the pillow with the skin and is helpful for sleeping through the double modification of the stone needle fiber and the nano silver; the combination of the two can make the pillow have the functions of antibiosis and health care.
