Abstract

The surface roughness has been analyzed in various ways so far. The surface profile analysis method using stylus and the fractal dimension method have been applied to conduct a more detailed analysis at this study. Air permeability was increased when LBKP mixing ratio and fillers addition increased, and when fines addition decreased. Roughness was decreased when LBKP mixing ratio increased, and when fines and fillers addition increased. Roughness and fractal dimension values had very high correlation when fines (R²=0.8667) and fillers (R²=0.8245) addition were changed, but they were very low correlation (R²=0.0018) when NBKP and LBKP mixing ratio changed. Therefore, analysis of fractal dimension value is suitable for handsheet surface analysis of small size such as fines and fillers, but it is not suitable for longer size such as NBKP and LBKP fibers. When fines and fillers addition were increased, fractal dimension values decreased because roughness of handsheet surface was decreased.
