Although wood pulp is the main raw material for production of cellulose nanofibrils (CNF), seaweed, agricultural waste, and recycled can also be used as materials. Despite requiring thorough cleaning, offers a cost-effective alternative CNF production. This study aims to explore feasibility utilizing derived from pretreated by comparing its quality bleached kraft virgin pulp. The performance ch...

The adsorption of xylan on pulp fibers improves the strength properties of paper. However, the optical properties are decreased significantly. The objective of our research was to bleach hardwood kraft pulp with adsorbed birch xylan by hydrogen peroxide and study the effect of bleaching parameters on paper properties. The bleaching parameters studied included bleaching temperature, time, initia...

Environmental and economic concerns are driving tissue paper manufacturers to improve understanding of the relationships between fibres, networks they form, forming process, final properties. This work investigated how pulp fractionation, refining, or addition microfibrillated cellulose (MFC) affect compromise absorbency strength 33 ± 2 g/m² model papers made bleached eucalyptus kraft pulp. The...

Cellulase-poor crude xylanases of Coprinellus disseminatus, strains SH1 NTCC 1163 (enzyme-A) and SH-2 NTCC 1164 (enzyme-B) produced under optimum conditions of solid-state fermentation (SSF), were used in bio-bleaching of wheat straw soda-AQ pulp in totally chlorine free (TCF) bleaching sequences. Kappa number reductions of 56% and 58% with respect to oxygen-delignified pulps were obtained afte...

Stabilization against thermal and photo-induced brightness reversion of high-brightness BCTMP (bleached chemithermomechanical pulp) by various sulfur compounds was investigated. Ethylene glycol bisthioglycolate and 3mercapto-1,2-propanediol were the most effective additives that provided bleaching action and prevented thermal and light-induced brighmess reversion. The stabilizing activity of th...
