Abstract Deep eutectic solvents (DESs) offer an appealing green medium for the activation of cellulose fibres to promote their swelling, reactivity, hydrolysis, disintegration, and solubility further processing. Typically, DES treatments are carried out below 5 wt% consistency even though a higher solids content could enhance fibre reduce solvent consumption. In this work, high-consistency (HC) mechano-chemical bleached softwood kraft pulp was elucidated using simultaneous treatment with...
Regenerated cellulose products are attracting increasing attention as sustainable alternatives to petroleum-based materials, especially in the packaging and textile industries. Ionic liquids (ILs) often described "green" options for dissolution due low toxicity volatility. Most studies on regeneration of utilize high-purity dissolving pulps, which known be more "reactive" than kraft pulps. Therefore, we investigated influence hemicellulose content solubility ability softwood pulps well grade...
Plasticizers are widely used to improve the elasticity of regenerated cellulose films, but academic research has thus far ignored possibility plasticizer blending. We studied effects glycerol, sorbitol, and maltitol on film properties based a systematic design for mixture experiments determined regression models correlate blend composition with properties. Our results showed that blending enabled us control tensile strength water vapour oxygen permeabilities, which key indicators evaluate...
