The role of hornification in the deterioration mechanism of physical properties of unrefined eucalyptus fibers during paper recycling, TAPPI Journal February 2024

ABSTRACT: Physical properties of cellulosic paper deteriorate significantly during paper recycling, which hinders the sustainable development of the paper industry. This work investigates the property deterioration mechanism and the role of hornification in the recycling process of unrefined eucalyptus fibers. The results showed that during the recycling process, the hornification gradually deepened, the fiber width gradually decreased, and the physical properties of the paper also gradually decreased. After five cycles of reuse, the relative bonding area decreased by 17.6%, while the relative bonding force decreased by 1.8%. Further results indicated that the physical property deterioration of the paper was closely related to the decrease of fiber bonding area. The fiber bonding area decreased linearly with the reduction of re-swollen fiber width during paper recycling. Re-swollen fiber width was closely related to the hornification. Hornification mainly reduces the bonding area of unrefined eucalyptus fiber rather than the bonding force. The work elucidates the role of hornification in the recycling process of unrefined eucalyptus fibers and the deterioration mechanism of paper physical properties, which will be helpful to control the property deterioration of paper and achieve a longer life cycle.

Editorial: Transform presentations to TAPPI Journal research papers by following basic steps, TAPPI Journal August 2024

ABSTRACT: Very often, important research findings are communicated in presentation form at industry conferences like those TAPPI holds. While this is a great way to highlight your work, it has some limitations when compared to a peer-reviewed TAPPI Journal paper. Presentations are limited to a specific event, while publishing papers in a peer-reviewed journal means that your work becomes part of scientific literature that is available to a broader audience. Also, a research paper allows for a more detailed explanation of the methods, data, and conclusions than the time-constrained format of a presentation.
