Abstract: This paper explores the effect of addition of cationic starch and chitosan separately and in combination on some of the important paper properties of mixed hardwood pulp. By adding cationic starch at 5 kg/t, the increase in strength properties was less than that obtained with the addition of chitosan at 0.5 kg/t, while both produced 17-18% ash. At that same ash level, the improvement in strength properties was further increased when both cationic starch and chitosan were used together as strength additives. The results conclude that chitosan is a better strength additive than cationic starch at the same ash level. FTIR analysis was also undertaken to explore the modifications that occurred in the paper after addition of cationic starch, chitosan, and other wet-end additives. The results showed increased hydrogen bonding occurred with the addition of chitosan. © 2017, Appita Inc. All rights reserved.
