Characteristics of Wood Cellulose Fibers Treated with Periodate and Bisulfite
Wood cellulose fibers were oxidized by periodate to obtain dialdehyde cellulose(DAC)fibers.The aldehyde group content,degrees of crystallinity and polymerization,and fiber length of treated fibers were characterized.The tensile strength of the test sheets made of treated fibers was also measured.The results showed that periodate oxidation significantly increased the aldehyde group content and the dry and rewet tensile strengths of the test sheets.Suifonation of the oxidized fibers by bisulfite improved the undried fiber water absorbency and the dry and rewet tensile strengths of the test sheets.
