Abstract: | The present paper studies the effect of chitosan, cationic starch and polyvinyl alcohol (PVA) as sizing agents to enhance
surface properties of kenaf paper. The polymers were incorporated into the sheets by spray application. The results clearly
showed that the addition of chitosan to a sheet formed from beaten fibers had excellent improvement in surface properties,
compared to the effect of other additives. Sizing quality of cationic starch fairly matched with the sizing quality of chitosan,
however, it was able to reduce the water absorption potential of paper more than chitosan at a same concentration. In most
other properties, particularly the most important property for printing papers, surface smoothness, chitosan-sized papers
are superior to the paper sized with cationic starch or PVA. |
