Wool Washing

Wool Washing
WOOL WASHING
The process of cleansing raw wool by a washing process conducted in a large machine generally with four bowls. The most usual detergents are soap and alkali used in various proportions for different wools in a considerable quantity of water. The temperature of the washing liquors is important and might be 120 deg. F. or 130 deg. F. in the first and second bowls with successive lower temperatures in the third and fourth bowls. The impurities removed are considerable, and might be 50 per cent or more of the greasy weight of the wool.
