Dissolving pulp from bamboo-willow
Cellulose, 2017The production of dissolving pulp from bamboo-willow (Salix salicaceae or Zhuliu in Chinese) was investigated. It is one of the new fast-growing tree species with strong cold resistance and can grow well in arid areas. Bamboo-willow chips were prehydrolyzed with phosphoric acid and subsequently pulped via the Kraft process.

Resin analysis in dissolving pulps
Bulletin des Sociétés Chimiques Belges, 1976AbstractA method based on gas and liquid chromatography was developed for analysis of wood pulp resins. Results obtained with sulphite and sulphate dissolving pulp resins are given and discussed.

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).

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.

Dissolving pulp from white press cuttings
TAPPI Journal, 2016Upgrading of white press cuttings into dissolving pulp was carried out by acidification followed by alkaline extraction. Acid treatment decreased ash content of white press cutting pulp from 11.25% to 0.33% at pH 2. The yield after acidification and screening was 87%.
