Abstract: | A kind of antimicrobial fibers, a composite of Chitosan-Dialdehyde Cellulose (C-DAC) fibers, was prepared by using commercially elemental chlorine-free (ECF) bleached kraft softwood cellulose fibers oxidized by periodate and then further grafted by chitosan with different molecular weights. The characteristics of the C-DAC fibers and physical properties as well as antimicrobial activities of the handsheet made of C-DAC fibers were measured. The results show that the dry and rewet tensile indices, antimicrobial activity against Staphylococcus aureus and Escherichia coli, can be improved significantly as the molecular weight of grafted chitosan on the dialdehyde cellulose fibers decreases. |
