Abstract

Kraft long fibres were found to improve tear strength much more effectively than mechanical long fibres despite having similar coarseness (roughly the same number of fibres per gram). Pure primary TMP fines had relatively high bulk corresponding to newsprint quality TMP. By freely combining the three furnish fractions from kraft and mechanical pulps, scattering of LWC base paper was improved by 27% and tear index by 7-24%. Handsheet bulk was unchanged but, due to improved smoothness, lighter calendaring was enabled, thus offering a possibility for improved paper bulk. Another means identified for improving bulk at a given tensile level is to mix a high number of mechanical long fibres with well-bonding mechanical fines. The produced data offers possibilities to design paper furnish in several ways depending on the desired critical properties.
