Class Information
Number: 162/21
Name: Paper making and fiber liberation > Processes of chemical liberation, recovery or purification of natural cellulose or fibrous material > Defibration by projection or explosion
Description: Processes combined with the separation of the fibers from each other (1) by subjecting them to a sudden and drastic release of pressure, or (2) by projecting the fiber clumps against a solid surface.
