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 ...

Studies on Dissolving Bamboo Pulp [PDF]
Bulletin of the University of Osaka Prefecture. Ser. B, Agriculture and biology, 1965 (1) Dissolving bamboo pulp can be manufactured by application of the processes of "sulphate pulping subsequent to prehydrolysis". When water cooking is applied for prehydrolysis, cooking conditions of 160℃ 4 hrs. and 165℃ 4 hrs.

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.

Enzymatically treated sulphite pulp to give dissolving-pulp characteristics
, 2013 Bleached cellulose with good end-properties (~90% ISO brightness, < 0.5 kappa number and substantially preserved cellulose integrity) was obtained by using a totally chlorine-free (TCF) biobleaching sequence. The initial pulp was subjected to an overall LQPo sequence.
