The effect of fiber dimensions of kuromatsu Asplund pulp on some properties of pulp, obtained by single-stage oxygen alkali pulping were studied. Yield, blightness, and kappa number were measured. With decreased fiber dimensions of Asplund pulp, yield, brightness and kappa number decreased and scattered respectively. So, it becomes evident that the reproducibility of the pulping results is affected significantly by the proportion of an fine size fraction (20 mesh pass fraction) in the starting materials. Therfore, to establish an generally accepted relationship between the cooking variables and pulp properties, (1) the fine size fraction should be removed as much as possible from the starting material, and (2) at least the amount of fine size fraction should be kept constant in the starting material.
