Bamboo refers to a manufactured cellulose fiber that is made from bamboo pulp with a solvent spun process. As part of the rayon fiber family, bamboo fiber can be produced in filament or staple form. It is not inherently antibacterial. Bamboo is a renewable resource and is more ecofriendly than other members of the rayon family. Commonly used for bedding and apparel, bamboo fiber is soft to the touch, lightweight, and breathable.
