Comparison of Soda, Kraft, and DES Pulp Properties of European Black Poplar
Kraft pulping as the dominant pulping method contributes to several environmental problems. To overcome these problems, environmentally friendly pulping methods have been investigated. In the last years, deep eutectic solvents (DESs) have been identified

Tailor-made alkaliphilic and thermostable fungal laccases for industrial wood processing
Background During the kraft process to obtain cellulosic pulp from wood, most of the lignin is removed by high-temperature alkaline cooking, released in the black liquors and usually incinerated for energy. However, kraft lignins are a valuable source of

Modification of kraft wood-pulp fibre with silica for surface functionalisation [PDF]
A new science strategy for natural fibre modification was devised in which glass surface properties would be imparted to wood-derived fibre. The enhancements known from addition of silane reagents to glass fibre–polymer composites could therefore be ...

Relationship between wettability of pulp fibers and tensile strength of paper during recycling
The wettability of the paper surface is greatly affected by the wettability of the pulp fibers. We conducted this study in order to understand the relationship between the wettability of a single fiber of recycled pulp and the strength of recycled paper,
