The cationic starch is a highly operable starch derivative and is widely used in papermaking to increase the paper strength. The cationic starch is positively charged and hence it is compatible with negatively charged agents such as cellulose, paper pulp, some artificial fiber, water containing inorganic substances, clay and highly active biopolymers. The cationic starch increase the retention level of filler. Titanium dioxide, clay, talcum and calcium phosphate are often added to the papermaking machinery and equipment to improve the impermeability for high-quality photocopy paper, writing paper and light-weighted paper. However, the paper loses its stretch intensity due to the increase in retention of filler and it seems that inertia filler reduces the total area ​​between the bonding of fibers. As the cationic starch is used to increase the strength property and retention of filler, it provides the characteristics of high retention to the high quality fillers as well as reduces the biological oxygen demand (BOD) and chemical oxygen demand (COD). The cationic starch can also be added to the beating apparatus to improve drainage and produce the high-quality paper, as well as improve the effectiveness of alum rosin glue.
