Two technical articles on preparing wool for spinning, apparently from a British trade or textile-institute publication. W. L. Thomas describes industrial raw wool scouring: the four-bowl washing set, soft water, soda ash, soap and synthetic detergents, suint washing, solvent cleansing, and backwashing after carding. P. P. Townend then covers carding wool for woollen yarns: the functions of the card, hand cards, the history of carding machines from Bourn, Paul and Arkwright, methods of condensing slivers, automatic feeds, and the action of a modern carding machine.
