See HANK.

Hank swift

Hanking machine

A revolving frame on to which a number of hanks or skeins or reels of yarn or roving are wound simultaneously. The frame normally comprises a number of parallel bars (some or all of which collapse to facilitate removal of the wound hank) mounted circumferentially on a cylindrical form. Traversing yam guides provide a pattern which enables the hank to be leased so that it can be unwound without entanglement after storage or, e.g., wet processing.

Hardness

1. When used in reference to water hardness is the total parts per million (ppm) of calcium an CaCO3 plus the magnesium expressed as equivalent CaCO3 [ppm hardness (as CaCO3) = (ppm Ca x 2.497 + ppm Mg x 4.116)]. 2. Used in reference to pulp to denote the degree of delignification.

Hare fibre (hair)

Harness
