The modes of action of the important commercial wet strength additives for paper are explained in terms of the physics and chemistry of the interfibre bonding areas therein. The theoretical principles expounded are then used to provide the experimentally-verified prediction that the naturally-occurring biodegradable aminopolysaccharide, chitosan, can function effectively to mitigate the adverse effect of water in papers.
