In the textile industry, a hank is a coiled or wrapped unit of yarn or twine (as opposed to both other objects like thread or rope as well as other forms such as in a ball, cone, bobbin(cylinder like structure), spool, etc). This is often the best form for use with hand looms, compared to the cone form needed for power looms. Hanks come in varying lengths depending on the type of material and the manufacturer. For instance, a hank of linen is often 300 yards (270 m), and a hank of cotton or silk is 840 yards (770 m).
