Although the importance of measuring fines in the thickness direction of paper is well recognized, currently available measurements are limited in precision and accuracy. Hence, we developed a new method for precise quantification of fines as well as filler distribution in the thickness direction of paper. Compared to the Beloit sheet splitting technique, this method offers superior quantitative information about fines distribution, especially near the surface.
A paper sample is typically split into 8 to 10 layers and the following results can be obtained:
The new method offers unique diagnostic capabilities for troubleshooting related to printing, linting, and curl. In addition, it can be used to accurately quantify the effect of a former rebuild, fabric upgrade, new wet-end chemicals, and other paper machine parameters related to fines and filler Z direction profiles.
- Fines and filler distribution in Z direction
- Fibre orientation distribution in Z direction
- Paper curl prediction
