Abstract

Many researches are carried out for developing the technology to substitute the surface sizing, although this process improves physical properties and water resistance of paper. This is because surface sizing has fundamental limitation to increase drying energy consumption and to restrict speed of paper machine. However, practical and effective technologies were not developed yet. In this study, we investigated the possibility of the substitution of surface sizing using internal starches, such as cationic starch and oxidized starch. To identify effects of internal starches on physical and optical properties, papers were not only made by adding internal starches into pulp slurry but papers surface sized with oxidized starch were also prepared to compare physical and optical properties. Consequently, tensile strength and internal bond of paper containing internal starches were higher than those of surface sized paper by controlling the type and addition level of cationic starch.
