bamboo fabrics are made from heavily pulped bamboo grass. making clothing and textile from bamboo is considered sustainable due to the lack of need for pesticides and agrochemicals. naturally disease and pest resistant, bamboo is also fast growing. compared to trees, certain varieties of bamboo can grow 1–4 inches long per day, and can even branch and expand outward because of its underground rhizomes. like cotton fibers, bamboo fibers are naturally yellowish in color and are bleached white with chemicals during processing.
