Cotton is the most common natural fiber in the world. It is a plant-based fiber that is almost pure cellulose, with softness and breathability that have made it popular for textiles. Cotton is versatile and used in a wide variety of market applications from apparel to bed linens and towels, as well as nonwoven hygiene products and medical and dental supplies. Other plant-based fibers include bast fibers like hemp, core fibers like jute, leaf fibers like sisal, and fruit fibers like coconut. Animal-based fibers like wool or hairs and silk fibers are also used for textiles.
