ABSTRACT:
The present invention provides an improved method for scouring wool. The method comprises differential heating of grease contaminants in the unscoured wool to at least partially liquefy the grease, absorbing the grease by the addition of a grease-absorbing material, and separating the grease-absorbing material from the wool. The method of the invention involves substantially less water consumption than current methods and is a more efficient means of producing wool.
