Abstract
A method for defibrating waste paper and dispersing contained asphalt and wax contaminants within the fibers. The waste paper is initially pulped with water and the resulting stock is then contacted with a high pressure stream of steam having a velocity in the range of 1200 to 1600 ft./sec. The mixture of steam and stock is passed through a mixing tube under highly turbulent conditions to defibrate the waste paper and disperse any asphalt, waxes, and other contaminants throughout the separated fibers. The resulting stock can be used in papermaking processes, particularly for the production of paperboard products.
