An encyclopedia article on the history and processes of wool and worsted manufacture. It covers early history from antiquity through England and the United States, the structure of the wool fibre, and the steps from scouring, carbonizing, mixing, oiling, carding and gilling through to spinning. It also describes fulling, teaseling and finishing of woolen cloth, utilization of wastes (shoddy, mungo, noils), and weighting of fabrics. Statistical tables give U.S. wool production, imports and supply 1906-1915 and world wool production since 1870, with a short bibliography.
