Bamboo Charcoal fiber is a natural and environmentally friendly recycled fiber derived from bamboo. Bamboo, known for its rapid growth and minimal need for management, can be easily decomposed by natural organisms. Through a high-temperature firing process, bamboo is transformed into bamboo charcoal, which is then finely ground and added to the fiber using precision techniques. Bamboo Charcoal Yarn boasts a rich mineral content and offers far-infrared rays, antibacterial properties, deodorization, anti-UV protection, excellent breathability, and wearing comfort. Its exceptional deodorizing function has earned it the moniker "breathed fiber."
