Abstract

Adsorption of any chemicals over pulp stock during wet-end operations in paper manufacturing is extremely important for effectiveness, waste treatment, close system operation and so on. This paper investigates the adsorption characteristics of AKD emulsions over various pulp blends containing bleached, unbleached fibres and secondary fibres obtained from some waste paper grades. Fibre suspensions with different properties were mixed with various amounts of sizing emulsions under different conditions and the amount of adsorbed sizing agents were monitored by gas chromatography studies. The optimum amount of sizing adsorption needs to be achieved giving higher retention, clear drainage and good water repellent properties. Work is believed to offer some useful information to especially papermills utilising waste papers at neutral or alkaline conditions.
