摘要：

Currently, widely used methods of measuring surface properties of paper are air leakage-type methods such as the Bekk smoothness method and Bendtsen roughness method. Measurements of the surface of paper in this air-leakage method may have advantages for the purpose of comparing differences between paper samples, but they have limitation of understanding of the variation in roughness within one sample. To measure the characteristics of paper surface directly, the profile can be analyzed by measuring the hill and valley of the surface by using stylus tip. Based on the measured data, it is analyzed by fractal geometry theory. It is known that the paper surface is not a single dimensional line and is not two dimensional plane, the result value between 1 and 2 can be expected when the surface of the paper in thickness direction is analyzed using a fractal dimension (FD). Comparing fractal dimension, Bendtsen roughness, and Bekk smoothness with R2 value, most of the pressing handsheets had meaningful levels of correlation. However, correlation of the results of the 3 times pressing was lower than the results of the 1 time pressing and 2 times pressing. © 2019 Korean Technical Assoc. of the Pulp and Paper Industry.
