The modern techniques try to replace the complicated, labor-intense treatment of the fibers with harsh chemicals – boiling in hot, concentrated alkaline or acidic concoctions under pressure. Catalytic Advanced Oxidation developed by Hydrogen Link finds application in the treatment and upgrading of natural cellulosic fibers extracted from plants – such as hemp, flax, jute ramie, kenaf, banana, sisal, etc. According to the article, Bast fiber up-gradation is made sustainable by the Catalytic Advanced Oxidation method, which involves hydrogen peroxide (H2O2) combined with Oxycatalyst to obtain clean, white natural cellulose fibers. The article claims that this method causes zero pollution due to the characteristics of chemicals used. The process also does not require the use of expensive instrumentation since it takes place at room temperature and neutral pH. The company states that the Catalytic Advanced Oxidation is capable of full degumming and delignification of the fiber-bearing plant (bast fiber or leaf fiber), thus resulting in clean cellulose fibers of high quality. This selectivity feature of Catalytic Advanced Oxidation represents the principal advantage in comparison to the typical "etching" processes with harsh chemicals. According to the company, the treatment of bast fibers is very flexible: it can be done on unrented, fresh plants, without preparation such as decortication (i.e. separating bast from hurd) or field- or water seasoning. Alternatively, it can be performed as a finishing step on pre-prepared, mechanically cleaned, decorticated, and retted bast strips of raw fibers.
