Abstract

When the disintegration of leather or other materials of fibrous structure e.g. paper, cardboard, cellulose, textile waste etc. the material to be fibrillated of normally occurring dimensions is disintegrated in a known type of cutter mill with addn. of water or aq. soln. This gives a prod. of optimum properties, free from the deterioration e.g. discoloration prod. by the tooth disc mills normally used in conjunction with the pre-disintegration in hammer or cutter mills of the as-received material e.g. leather scrap and the final refining in ball mills, Hollanders etc.
