In a previous study, Hassan et al (2010a) found that nanopaper sheets made from MFC isolated from bagasse pulp had high wet and dry tensile strength and also high transparency. In addition, pretreating bagasse pulp with xylanase and dilute alkali resulted in MFC paper sheets with higher wet and dry tensile strength compared with those from untreated bagasse (Hassan et al 2010b). In the current study, MFC isolated from bagasse pulp that was pretreated with xylanase enzymes was used to improve the properties of paper sheets made from bagasse pulp.
