A cascaded process to upgrade bleached bamboo pulp into dissolving pulp and arabinoxylan
Carbohydrate PolymersThe dissolving pulp preparation from bleached kraft pulp while realizing the high-value application of hemicellulose fraction is of great significance for improving the overall economics of the process. This work proposed a two-step cascaded process of deep eutectic solvent (DES) pretreatment combined with mechanical refining for the co-production of ...

The potential of biosulfite pulping in dissolving pulp production
Enzyme and Microbial Technology, 1998Abstract Biological alternatives which could aid the hemicellulose and lignin removal from dissolving-grade pulps imply the use of microorganisms to pretreat wood chips prior to pulping (biopulping) and/or use of enzymes to pretreat pulp prior to bleaching (biobleaching).

Dissolving pulp from jute stick
Carbohydrate Polymers, 2015Jute stick is woody portion of jute plant, which remain as leftover after extracting bast fibre. Presently, it is being used for fencing in the rural area. In this investigation, biorefinery concept was initiated in producing dissolving pulp from jute stick by pre-hydrolysis kraft process.

Enzymatic and alkaline treatments of hardwood dissolving pulp
Cellulose, 1998Dissolving pulp was solubilized in 9% NaOH, resulting in 32% solubilization of the pulp. Most of the pulp hemicelluloses were solubilized during this treatment. During the alkaline treatment the cellulose crystalline form was converted from cellulose I to cellulose II.

Production of Dissolving-Grade Pulp
2011Dissolving-grade pulps are commonly used for the production of cellulose derivatives and regenerated cellulose. To obtain products of high quality, these so-called “special” pulps must fulfill certain requirements, such as high cellulose content, low hemicellulose content, a uniform molecular weight distribution, and high cellulose reactivity.
