Abstract: The article focuses on the use of neutral rosin-alum size in paper-making. The use of rosin size is widely prevalent in paper mills in Egypt as it is inexpensive, abundant and easy to process. Rosin-sized paper has low thermal decomposition temperature. An experiment was carried comparing paper produced from a neutral rosin-alum size and those from acidic rosin-alum size and neutral-alkaline atkylketene dimer (ADK) size. ADK sizing resulted in higher permanence of paper and print.
