specific Embodiment

[0020]Specific embodiment: 98% sulfuric acid and Tai Chi stone are heated to 50-90 ° C and washed for 1-3 hours according to the ratio of 5-9% (w / w), filtered through a 100-500 mesh filter screen, and then added 2-10 times the mass Wash three times with several deionized water for 10-30min; after drying at 100-200 ℃ for 1-5h, add 2-5 times the mass of deionized water at room temperature, and grind at 50-600rpm for 1-3h with a nano high-speed stirring ball mill , and then under nitrogen protection, calcined at 400-600℃ for 1-4h, 600-800℃ for 1-4h, 800-1200℃ for 1-4h, 1200-1500℃ for 1-3h, and then added to 2- 5 times the mass concentration of 0.1-2% non-foam dispersant sodium polyacrylate dispersant aqueous solution and 0.1-2% cellulose-based viscosity-adjusting auxiliary are added at a stirring speed of 100-300 rpm. By pre-spinning injection, the suspension of Taiji stone, which has the functions of far-infrared, anti-ultraviolet, antibacterial, and the functions of improving h...

Abstract

The invention provides a preparation method of Taichi stone cellulose fiber. According to the method, a Taichi stone suspension with far infrared, uvioresistant and antibacterial functions and a cellulose sulfonate solution are mixed uniformly by injection before spinning, and a finished product is obtained by wet spinning and aftertreatment; according to the obtained Taichi stone cellulose fiber,Taichi stone content is 1%-8% (w / w), far infrared emission rate is higher than or equal to 90%, UPF (ultraviolet protection factor) is larger than or equal to 50, bacteriostasis rate is higher than or equal to 99%, breaking strength is larger than or equal to 2.5 cN / dtex, elongation at break is larger than or equal to 15%, color fastness to washing is higher than or equal to level 4, and the Taichi stone cellulose fiber can convert high-frequency beta waves (14-30 Hz) in human brain waves into brain wave theta waves (4-8 Hz) and alpha waves (8-14 Hz) with low frequency spectra. The Taichi stone cellulose fiber not only has excellent far infrared, uvioresistant and antibacterial functions, but also has functions of relieving depression and improving sleep, breaking strength and elongationat break are higher, performance is lasting and stable, besides, the technology is mature, the process is simple and easy to control, and industrial production is facilitated.

Description

technical field [0001] The invention specifically relates to a preparation method of taiji stone cellulose fiber. Background technique [0002] Taiji stone is a natural ore, silicic quartz ore, except that it contains 87.53% SiO 2 In addition, it also contains a large amount of K 2 O, CaO, TiO 2 and other oxides and various trace metal mineral elements such as titanium, potassium and germanium. Nano Tai Chi particles with a diameter of 97-189.2nm can refine water molecules, improve human blood microcirculation, promote cell activity, increase metabolism, and relax mood; Converted into low-spectrum brain waves theta wave (4~8Hz) and alpha wave (8~14Hz), the function of relieving depression and improving sleep; also has excellent anti-ultraviolet function, its line protection factor UPFAV reaches 232.87, UPF level 50 +; In addition, the Tai Chi stone also has good antibacterial function, the antibacterial rate of Klebsiella pneumoniae is 99.8%, and the bacteriostatic rate ...
