Abstract

The effect of the freeness of pulp slurries on turbidity and transmittance of papermaking stocks was investigated using beaten bleached hardwood pulp stocks with freeness ranging from 651 mL to 403 mL CSF. Also the influence of fiber length on the turbidity and transmittance was examined with fractionated pulp stocks. Increases in stock consistency increased the turbidity. Transmittance of stock samples decreased, however, with the increase of stock consistency. Second order equations and exponential equations have been obtained as regression equations for the turbidity and transmittance of these stock samples, respectively.
