In contrast, the tear index and tensile index, important parameters representing the mechanical properties, of PVA fiber paper were far lower than those of cellulosic paper. The discrepancy can be explained by the fact that the PVA fiber paper obtained herewas made from the PVA fiber instead of PVA solution, the latter of which can be indeed used to make paper sheet with the tear indexand tensile index similar to those of cellulosic paper. As a matterof fact, PVA fiber possesses inherently poor mechanical proper-ties, which makes it inferior to cellulosic paper when applied tomake paper. However, in our present work, significant improvement in the mechanical properties of PVA fiber paper using CNCC as strength agent was successfully achieved, which would set an attractive base for an ecofriendly and cost-effective manufacturing potential for the production of PVA fiber paper sheet with desired mechanical properties.
