Abstract

The fines character impact on sheet strength and density was studied by isolating fines from five mechanical pulps, adding them to the same base fibre fraction and making hand sheets. A threefold difference in strength contribution was found depending on fines character. Flow cytometry as used as a rapid method to quantify shape factor and size distribution of fines. Varying lignin distribution in different size classes of fines was detected with an automated fluorescence microscope.
