PHYSICAL CHEMICAL PROCESS FOR PRODUCTION OF VEGETABLE FIBERS

摘要

The invention regards a process through which it is possible to extract cellulose fibres contained in the Liberian vessels of vegetable species such as linen, ramie, hemp, Spanish broom, kenaf, jute, etc. The process is composed principally of a stage of digestion of the initial material in a hot aqueous alkaline solution, of a stage of compression in an autoclave with hot air, and a stage of rapid decompression. A further stage can consist in an ulterior softening of the fibre, by processes of enzymatic digestion or by processes of the mechanical kind.
