Improvement of bleached wheat straw pulp properties by using aspen high-yield pulp

Bioresource Technology, 2012
The bleached wheat straw pulp (BWSP) accounts for about 25% of the virgin fiber supply in the Chinese Pulp and Paper Industry. As a non-wood chemical pulp, BWSP is known to have low bulk, low light scattering coefficient and poor drainage due to its high content of parenchyma cells.

The apparent yield stress of pulp fiber suspensions

Journal of Rheology, 2010
The apparent yield stress is one of the most important rheological properties of pulp suspensions in designing process equipment for the pulp and paper industry. Therefore, determining a reliable apparent yield stress measurement technique is of importance, not only for pulp suspensions but for any fluid exhibiting yielding behavior.

Production of high yield bleached hardwood kraft pulp: Breaking the kraft pulp yield barrier

TAPPI Journal, 2011
A modified kraft pulping process has been developed that successfully breaks the traditional hardwood kraft pulp yield barrier. The process produces fully bleached, high brightness hardwood kraft pulp with a yield of greater than 53% on wood. Details of the development and processing steps, along with various recovery cycle impacts, are discussed.

Evaluation of current methods to estimate pulp yield of hemp

Industrial Crops and Products, 1994
Abstract Large-scale evaluation of hemp stems from field trials requires a rapid method for the characterization of stem quality. The large differences between bark and woody core in anatomical and chemical properties, make a quantification of these two fractions of primary importance for quality assessment. This paper evaluates accuracy and power of

Effects of Pulped Soybean Silage on the Milk-yield of Cows

Nature, 1961
As a result of co-operative investigations carried out with the Research Institute for Animal Physiology, a report has already been published1 on the summer feeding of green soybeans, in which it was shown that the relative protein-deficiency in green maize silage having a high dry-matter yield may be compensated by the flowering, pod-forming soybean ...

Brightening of mechanical and high-yield pulps

TAPPI Journal, 2013
This work lays out the general principles of the brightening of mechanical pulp. The author presents a practical discussion of the brightening processes for both reductive (sodium hydrosulfite or dithionite) and oxidative (hydrogen peroxide) chemicals. Each of these chemicals has its advantages, disadvantages, and most suitable applications.
