Electron-processing technology: A promising application for the viscose industry

Electron beam irradiation of cellulose

“…From a mechanistic perspective, the electron beam treatment disturbs the crystalline structure of the cellulose, thus allowing the penetration of chemicals into the crystalline regions (Horio et al, 1963;Fischer and Goldberg, 1987;Stepanik et al, 1998Stepanik et al, , 2000. This results in a reduction of up to 50% in carbon disulfide and 30% caustic usage, according to Stepanik et al (1998). The DP of viscose pulp appears to remain relatively constant after a dose of 25 kGy (Stepanik et al, 2000).…”

Preparation and Characterizaiton of Fe3O4/Regenerated Cellulose Membrane

“…The process of cellulose dissolution using different cellulose solvents provides a new method for the production of regenerated cellulose and can be used in various applications. The cellulose morphology changed after the dissolution and regeneration processes which affected the properties of the regenerated cellulose produced (Mohd Saidi et al 2016;Stepanik et al 1998). Recently, hybrid composite materials have attracted more interest to many researchers in order to achieve excellent properties as compared to the parent material.…”

Improving enzymatic hydrolysis of industrial hemp (Cannabis sativa L.) by electron beam irradiation

“…There have been many studies on the degradation of lignocellulose by high-energy radiation (Wasikiewicz et al, 2005), a decrease in the degree of polymerization (Taká cs et al, 1999;Bouchard et al, 2006) and the micro-structural changes of irradiated cellulose pulp (Dubey et al, 2004), which lead to an increase in the carbonyl contents of cotton cellulose (Taká cs et al,2000;Lam et al, 2000;Borsa et al, 2003) and jute fiber (Khan et al, 2006), and the improvement of the accessibility of the cellulose crystalline regions to reagents (Stepanik et al, 1998). Those researches supported the technical feasibility of the irradiation as the pretreatment of biomass and resulted in the many works for the application of irradiations on the lignocellulose treatment (Smith et al, 1985;Rahayu et al, 1993;Awafo et al, 1995).…”
