Abstract

In this research, the effect of cellulose nanofibers on the properties of handsheet paper made from industrial bagasse pulp was investigated. Nanofibers, produced from alpha cellulose of softwoods using grinding method, were added 20 wt% to the handsheet paper. Nanopaper- handsheet composed of 100% cellulose nanofibers- was also prepared. Results indicated that using nanofibers increased water drainage time of the pulp. Addition of nanofibers to the handsheets increased the optical transparency and density while sheet thickness decreased. Papers made with 20 wt% nanofibers showed higher tensile strength than those prepared with pure bagasse fibers. Nanopaper possessed the highest tensile strength. Tear strength was negatively affected by using cellulose nanofibers in such a way that the lowest tear strength obtained for nanopaper. Never eless with Addition of nanofibers to the handsheets in said conditions tear strength decrease but this decreasing of statistical viewpoint wasn't meaningful.
