Sizing behavior of handsheets, which were prepared from thermomechanical pulp (TMP) with alkylketene dimer (AKD), was studied in terms of conditions of the handsheet-making. AKD content in the TMP handsheets increased with increasing the AKD addition level, and the addition of a polyamideamine - epichlorohydrin resin (PAE) clearly enhanced AKD retention as well as the resultant sizing performance. Although drying
of the wet TMP webs at 20℃ led to no or quite low sizing
level, the AKD-sized TMP handsheets had higher sizing degrees with increasing the temperature of heat treatment. Scanning electron microscopic observations of the AKD-sized TMP handsheets showed that AKD emulsion particles were present on pulp fiber surfaces independently without coagulation in the TMP handsheets dried at 20℃. Heat treatment of the AKD-sized hand sheets resulted in disappearance of the AKD emulsion particles by their melting and spreading. The addition of calcium carbonate filler to the TMP suspensions did not influence on AKD content in the TMP handsheets. Nevertheless, their sizing degrees clearly
increased by the addition of CaCO₃) filler. Probably, AKD molecules adsorbed on the CaCO₃) filler particles contribute to the enhancement of sizing performance. Thus, AKD can give sizing features effectively to the TMP hand sheets, when they are made under suitable conditions.
