    Abstract

    The effect of eucalyptus chemical pulp fines on filler retention and paper properties was examined.
    Different quantities and qualities of fines were studied, and the benefit of pre-mixing fines and fillers before addition, compared to separate addition, was evaluated. As expected, fines enhanced paper properties, but retarded the drainage.
    The qualities of fines had a strong influence on paper strength properties and drainage of the pulp furnish. Fillers did not retard drainage; they had a positive effect on optical properties but impaired paper strength. In general, the retention of fillers was minor compared to fines.
    Retention, strength and optical properties of resultant paper were improved by addition of pre-mixed fines and fillers to pulp furnish. This improvement was achieved at the cost of significantly reduced drainage.
