Bamboo charcoal is known as "black diamond" and is known as "the new guardian of environmental protection in the 21st century". Mao bamboo is used as raw material to form bamboo charcoal after bamboo is dried and carbonized at 800 degrees Celsius. Bamboo charcoal fibers are made by nano-technology. First, bamboo charcoal is powdered, then nano-bamboo charcoal powder is processed by high-tech technology. Then, the traditional process of chemical fiber preparation is used to spin and form the qualified bamboo charcoal fibers.

Bamboo charcoal has strong adsorption and decomposition ability, can absorb moisture, dry, deodorize and antimicrobial properties, and has negative ion penetration. The most distinctive feature of the fiber is that each bamboo charcoal fiber has a honeycomb-like micro-porous structure running through the inside and outside. This unique fiber structure design can make the function of bamboo charcoal play out 100%.
