1. Bamboo charcoal fiber
Bamboo charcoal fiber is another brand-new environmental protection material with excellent performance developed by using bamboo resources. After the bamboo is processed by a high-temperature drying and carbonization process at 800°C, bamboo charcoal is formed, and then micronized by nanotechnology (nano-level bamboo charcoal powder) through high-tech processing, and then using the traditional chemical fiber preparation process, it can be spun into shape. Prepare qualified bamboo charcoal fiber. The black lacquered bamboo charcoal fiber has the reputation of "black diamond" in the Japanese market. Bamboo charcoal is mainly composed of carbon, hydrogen, oxygen and other elements. It has a hard texture, fine and porous, and strong adsorption capacity. The function of deodorization, antiseptic and odor absorption. Nanometer bamboo charcoal powder also has good antibacterial and sterilization effects. Bamboo charcoal can absorb and neutralize the acidic substances contained in sweat, achieving the effect of whitening the skin. Moreover, bamboo charcoal is also a good far-infrared and negative ion emission material. It not only has natural and environmental protection characteristics, but also has many functions such as far-infrared emission, negative ions, heat storage and warmth, and is suitable for wearing clothes. The function of bamboo charcoal is permanent and will not be affected by the number of washings.
Bamboo charcoal is made of moso bamboo that has been grown for more than 5 years and is fired in a kiln. Bamboo charcoal is born with finer pores and honeycomb, and then melt-spinning with polyester modified chips that have a honeycomb microporous structure trend. production. The difference of the fiber is that each bamboo charcoal fiber has a honeycomb-like microporous structure that penetrates the inside and outside. The superiority of the bamboo charcoal fiber is derived from the microporous structure inside.
It can be seen that the far-infrared emission rate of bamboo charcoal fiber is as high as 0.87, which is 0.05 higher than that of far-infrared emission materials. Infrared emissivity is high.
2. Research as a wave absorber
Bamboo charcoal fiber has super adsorption performance. The bamboo charcoal fiber and polymer are compounded to form a bamboo charcoal fiber polymer composite. Magnetic medium is added to the composite to adjust the electromagnetic performance parameters, thereby preparing a wave-absorbing composite material. The bamboo charcoal core shell can also be mixed and sintered with spinel ferrite, for example, mixed with Ni.sZnFe2O4 to prepare a wave-absorbing material.
