Nano carbons extracted from the inside of the bamboo cane itself with pure oxygen at high temperature are added to the bamboo viscose. This modified functional system produces a thread that protects against UV rays, preserves heat, is antimicrobial and deodorising, and improves blood circulation. It has a porous structure similar to gas filters, therefore it absorbs and decomposes benzene, phenol, methyl alcohol and other harmful substances. Breathable and biodegradable fabric. The effects listed are permanent and are not affected by washing, the particles are incorporated into the fibre and therefore long-lasting. Thermal regulator: due to the porous nature of bamboo charcoal, it not only feels cool on hot days but is also a great insulator against the cold. It produces negative ions, therefore it stimulates the blood microcirculation.
