Rheological behavior of magnetic pulp fiber suspensions, TAPPI Journal June 2021

ABSTRACT: This paper is focused on the rheology of magnetic pulp suspensions in absence and presence of an external magnetic field. Magnetic fibers were prepared by the lumen loading method using bleached eucalyptus fibers and cobalt ferrite (CoFe2O4) nanoparticles. The effect of mass consistency, temperature, concentration of magnetic fibers, and magnetic field strength on yield stress and apparent viscosity of the suspensions were investigated. In the absence of an applied field, a dependence of yield stress with consistency, as well as with the percentage of magnetic fibers present in the suspension, was found. In flow tests, all the suspensions exhibited shear-thinning behavior, showing that the viscosity is only affected by the consistency of the suspension. On the other hand, magnetorheological measurements show a negative effect of the applied magnetic field on the viscosity of the suspension.

Editorial: Let's talk tissue!, TAPPI Journal July 2019

ABSTRACT: In this issue of TAPPI Journal (TJ), researchers Olejnik and Pelczynski of Lodz University of Technology in Poland and researcher Bloch of the University of Gre-noble Alpes in France use an experimental device to measure the liquid absorption properties of tissue (p. 417). The device, called the eXtended liquid penetration analyzer (XLPA), was initially built at the Institute of Papermaking and Printing at the University of Lodz. Results from the study published here showed that the XLPA measurements were in good agreement with the ISO 12625:-8:2010 standard measurements. The researchers believe this method could ultimately help mills characterize the liquid absorption of their tissue in a better and faster manner.

Papermaking properties of bacterial nanocellulose produced from mother of vinegar, a waste product after classical vinegar production, TAPPI Journal April 2020

ABSTRACT: Bacterial nanocellulose (BNC) has gained a lot of attention in recent years due to its nano-size-derived properties. Although it is essentially chemically similar to plant-derived cellulose, it has smaller size and is enriched in free hydroxyl groups, which greatly improve mechanical properties of reinforced paper. However, although BNC has some unique features, it comes at a high price. In this paper, we introduce a new solution for BNC production. We have isolated bacterial nanocellulose directly from agro-industrial waste—mother of vinegar—and used it in the production of paper sheets. We show here that paper sheets made with the addition of only 10% bacterial nanocellulose from mother of vinegar substantially improved basic mechanical as well as printing properties of paper.

Editorial: TAPPI Journal research highlights from 2019, TAPPI Journal January 2020

ABSTRACT: As we move into 2020, it's interesting to look back at the research topics that were covered in TAPPI Journal (TJ) the previous year. Members of the TJ editorial board organized diverse special issues on lignin, coating ,forming, and diverse papermaking and biorefinery topics, which are discussed in the following sections.

Alternative “green” lime kiln fuels: Part II—Woody biomass, bio-oils, gasification, and hydrogen, TAPPI Journal May 2020

ABSTRACT: This paper is the second of a two-part series on “green” lime kiln fuels. The first part of this work reviews the use of pulp mill and recovery byproducts as either full or partial replacement of oil or natural gas in the kiln. The second part reviews the use of various forms of woody biomass, bio-oils, gasification and hydrogen as potential carbon neutral or carbon-free lime kiln fuels. Several of these options require specialized burners to supply the fuel to the kiln and high-quality metallurgy to withstand the acidic conditions of the fuel.
