Effect of Electron Beam Irradiation on the Properties of Softwood Unbleached Kraft Pulp

Journal of Korea Technical Association of The Pulp and Paper Industry, 2015
Electron beam irradiation is also an eco-friendly treatment compared to other physical and chemical treatments. In this study, we attempted to evaluate the possibilities of energy savings by applying electron beam irradiation to the refining process. After softwood unbleached kraft pulp (UKP) was irradiated with electron beams at 50 and 100 kGy, it was

Fiber Modification of Unbleached Kraft Pulp with Laccase in the Presence of Ferulic Acid

BioResources, 2013
Unbleached kraft pulp fibers were modified with laccase and ferulic acid (FRC) to improve their physical strength properties in paper products. The optimal conditions of laccase-FRC modification were examined in terms of the physical properties of pulps. The effects of laccase-FRC modification on the carboxyl group content and surface lignin content of
