Eco-Thermal selected bamboo naturally grows in Szechuan, China. As a renewable resource, a bamboo forest regrows in 4–5 years, while a tree forest takes 60 years.
The bamboo is dried and heated at 800∘C until it becomes bamboo charcoal.
The bamboo charcoal is further processed to be turned into micro-particles.
Ultra-fine bamboo charcoal micro-particles are embedded into cotton or polyester fiber.
The fiber is then drawn into yarn, and processed into Eco-Thermal fabrics.
