Wool

Wool is the textile fiber obtained from sheep and other animals, including cashmere and mohair from goats, qiviut from muskoxen, hide and fur clothing from bison, angora from rabbits, and other types of wool from camelids.[1] Wool consists of protein together with a small percentage of lipids. In this regard it is chemically quite distinct from the more dominant textile, cotton, which is mainly cellulose.
