Preliminary Study on the Synthesis and Applicatin of Cationic Chitosan for AKD Neutral Sizing

摘要：

Cationic chitosan derivate was synthesized with water-soluble chitosan,acrylamide(AM)and methacrylic acid ethyl trimethylammonium chloride(DMC)by graft copolymerization,and it was used to make cationic AKD emulsion.Hardwood pulp,soft wood pulp and their mixed pulp were used to test the sizing effect of the AKD emulsion.The effects of monomer ratio(nAM:nDMC)and the curing time on its sizing performance were discussed.Preliminary studies indicated that using the cationic chitosan improved the sizing performance of the AKD emulsion and shortened its curing time.
