Abstract The characteristics of cellulose nanofibers (CNFs) depend on many factors such as the raw material, type and intensity pre-treatment, severity mechanical defibrillation process. relationship among is complex but crucial in determining final, fit-for-use CNF properties. This study aims to find between properties morphology, aspect ratio, nanofibrillation yield, transmittance cationic de...

Abstract The effect on softwood fiber wall nanostructure of kraft cooking, oxygen delignification and refining was evaluated by X-ray scattering. A recently developed simulation method for modelling small angle scattering (SAXS) data used to estimate the apparent average sizes solids (AAPS) interstitial spaces in (AACS). Fiber saturation point wide were also calculate pore volume crystallite si...

Wheat straw pulp can be considered to be one of most important raw materials for specialty and functional paper products. Bleaching sequences involving laccase and xylanase were applied to bleach wheat straw pulp. The bleached pulp properties after a sequence of xylanase (X), laccase (L), and extraction (E), i.e. XLE, were compared with those of LE and LEX sequences. It was found that the XLE b...

Two woody legumes species (Chamaecytisus proliferus L.F. ssp. palmensis and Leucaena diversifolia) were evaluated for integrally exploitation. The raw material was subjected to autohydrolysis under variable operating conditions which provided a liquid phase rich in hemicellulose oligomers and a solid phase that was used to obtain cellulose pulp and paper sheets by using organosolv procedures. T...
