Abstract

In order to unravel fundamental mechanisms governing property development during high consistency (HC) and low-consistency (LC) refining of thermo-mechanical pulping (TMP), characterization of pulp fibre development at the cell wall level was carried out. Both HC and LC refining significantly enhance the internal fibre development (IFD) with the latter being more energy-efficient. The lFD was identical between HC and LC pulps when compared at the targeted tensile strength 40 Nm/g of handsheets providing the basis for energy efficiency of LC refining. External fibre development and the resulting fines development were very different between the two processes. Mechanisms of fibre development during HC and LC refining were explored which appear to govern most physical and optical properties of the pulps.
