Cationic starch represent high performance starch derivatives widely used by paper manufactures to increase strength and retention.
Cationic starch apparently improve the retention of fillers are frequently incorporated in the furnish of a paper machine to improve the opacity of high grade printing paper, writing paper, and light weight paper. With increasing filler retention, the sheet lose strength, apparently because the inert filler reduces the number of sites for fiber-to-fiber bonding. Because Cationic starch acts both to improve strength properties and filler retention, it gives high strength properties at high level of filler retention. A reduced BOD & COD are also achieved.
Cationic starch is also added at the beater to improve drainage on the wire, better sheet formation, and enhancement of the sizing efficiency of an alum-rosin size.
