Nano carbons extracted from the inside of the bamboo cane itself with pure oxygen at high temperature are added to the bamboo viscose. With this modified functional system a thread is obtained with the following characteristics: protection from UV rays, heat preservation and antimicrobial, deodorizes, 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 fiber and therefore long-lasting. Thermal Regulator Due to the porous nature of bamboo charcoal, they not only feel cool on hot days but are great insulators against the cold. It produces negative ions, therefore stimulators of blood microcirculation.
