Abstract
High-yield pulp (HYP) is gaining increasing interest in papermaking, the presence of anionic trash has been limiting its application in high-end paper products such as fine papers. In order to control the anionic trash of HYP, the performances of three anionic trash catchers in terms of charge control and fiber fines and filler retention enhancement were compared in a laboratory study. It was found that a poly-DADMAC based commercial product had the highest efficiency. The use of CPAM/Bentonite system resulted in highest fiber fines and filler retention. The best anionic trash control was achieved when HYP was treated separately.
