    Description

    In order to circumvent the problem of altering the sheet composition to increase bonding, in this study the bonding was increased by wet pressing and press drying sheets to various levels of RBA. The operating regime problem was then studied by interpreting the tear relative to bonding (where bonding is measured as T/Z, Tensile index/Zero span tensile index) relationship in whole TMP, its fractions and mixtures of these fractions. In addition the effect of fiber length on the tear strength at various bonding levels was studied using the data obtained from the mixture studies.
