A short dictionary entry defining cottonizing as the process of breaking down flax, hemp, jute, cane and similar fibers into a short staple that can be processed on cotton machinery. It describes two patents: P. Claussen's 1851 chemical process using carbonate of soda, potash and sulphuric acid, and Lyman's 1858 "fiber-gun," which uses high-pressure steam. It also notes that there are many variations of the alkali and acid treatment, with washing, bleaching and drying steps.
