Evaluating hardness and the S-test, TAPPI Journal March 2019

ABSTRACT: The corrugated industry typically quantifies crush resistance using the Concora corrugated medium test (CMT) on fluted medium or flat crush on combined board. These tests compress the materials until the point of complete failure of the flutes. Combined board elastically resists crushing forces until a certain point, the hardness of the structure, while additional load causes permanent damage and deformation. This study investigates how hardness can be measured directly from a load curve collected during CMT (or flat crush) testing and how it varies throughout the North American paper supply. It also explores how hardness corre-lates with the values obtained from the newly developed S-test. This new test method deserves further study as a potentially more appropriate specification for crush resistance of corrugated medium.

Controllable anisotropic properties of wet-laid hydroentangled nonwovens, TAPPI Journal March 2019

ABSTRACT: For nonwovens, fiber orientation distribution is an important structural characteristic that directly influences the anisotropic properties of the materials. Different Vslurry/Vbelt ratios were adopted to fabricate nonwovens during the wet-laid process. The results indicated that fiber orientation distribution of nonwovens can be regulated by adopting different Vslurry/Vbelt ratios owing to the web-forming principle of wet-laid techniques. Mechanical tests showed that both wet and dry tensile strength of nonwovens in different angle directions present anisotropy under different Vslurry/Vbelt ratio parameters. A liquid spreading distribution experiment proved that liquid spreading length and area of nonwovens could be manipulated using different Vslurry/Vbelt ratios in the fabrication process. Therefore, specific anisotropic properties of wet-laid hydroentangled nonwovens can be realized by controlling the process parameters for particular end-use applications.

Size distribution analysis of microstickies treated by enzyme mixtures in papermaking whitewater, TAPPI Journal March 2019

ABSTRACT: Microstickies present a formidable challenge for papermakers. Many strategies have been explored o control them. Enzyme treatment is a promising technology, but the mechanism of its action has not been determined, thus inhibiting further application of this new technology. This study investigated characteristics and size distributions of microstickies treated by esterase-cellulase mixtures. Determination of particle size and number was accomplished using a modified flow cytometer, which combined streaming capillary flow, laser-based particle size analysis and fluorescent dye tracing. The results showed that treatment of samples with enzyme mixtures induced size reduction of the larger microstickies. This effect was most dramatic for 1:1 ratios of esterase to cellulase. The treated particles were more stable than untreated ones. The smaller microstickies treated with some ratios of esterase and cellulase tended to aggregate over time.

Editorial: TAPPI Journal reinstates the “Technical Brief” short-form research paper, TAPPI Journal June 2019

ABSTRACT: For many years, TAPPI Journal (TJ) accepted submissions of “Technical Briefs” (also known as Technical Notes or Brief Notes) in addition to the full-length papers peer-reviewed papers that you have typically seen in more recent years. The TJ Editorial Board is once again accepting these short-form papers, as readers may have noticed in the last issue with publication of Tom Lindstrom’s short nanocellulose re-view (TAPPI Journal 18[5]: 308[2019]). Another Technical Brief appears on p. 391 of the current issue.
