Wool, fiber made from the fleece of the domestic sheep. Elasticity resulting from the molecular structure of wool and resiliency from its crimp make wool fabrics crease resistant. Fine wool will stretch one-third its length. Wool is warm because its fibers are nonconductors of heat and its crimp per mits it to enmesh still air. It is highly absorbent and releases moisture slowly. Its tensile strength is one fourth greater than that of cotton. Sheet, usually of heavy woolen, or partly woolen, cloth, for use as a shawl, bed covering, or horse covering.
Technology and ingenuity are creating the capability of these fabrics to provide high quality and functional products.
