Image analytical monitoring of paper quality - a feasibility
ABSTRACT: We evaluated 14 selected paper quality parameters using new image analytical techniques for characterization and monitoring of paper quality (multivariate AMT regression). We tested the technique on six major paper types. Of the parameters tested, 13 could be modeled with only minor optimization of the initial experimental image recording parameters. Although this analysis was performed in the laboratory with static sheets of paper, this new “remote sensing” image technique shows promising application potential for online product monitoring of the specified physical qualities.

Anthraquinone pulping of kudzu (pueraria lobata), TAPPI Journal December 2024
Authors: Peter W. Hart, Brian N. Brogdon, and Jeffrey S. Hsieh | TAPPI J. 76(4): 162(1993) - ABSTRACT: Kudzu was pulped underpulping conditions for kraft, kraft-AQ, soda, and soda-AQ processes. Anthraquinone addition increlased the carbohydrate content of the brownstock pulp for all cooks. Anthraquinone addition lowered the broumrtock kappa number while reducing the chemical demand. Brownstock ~om selected pulping sequences was tested to determine tear strength, tensile strength, burst strength, and~eeness. The broumstock was also subjected to a CED bleaching sequence. For the bleached pulps, viscosity and average fiber length were determined.
