Abstract

This study was carried out to evaluate the possibility of paper properties improvement by the use of GCC-MFC composite filler. Three different condition (GCC-c-starch, GCC-c-starch-MFC, GCC-MFC-c-starch) were applied to pretreat GCC. Two MFCs were prepared from HwBKP by the application of different two grinding number (30 and 60) in order to change the fibrillation degree. Although no significant differences in opacity were not observed by the GCC treatment conditions, the highest tensile index, burst index and stiffness in this study conditions were obtained by the application of GCC-c-starch-MFC sequence. The highest filler retention and formation index were obtained by GCC-c-starch sequence. Bulks obtained from GCC-c-starch and GCC-c-starch-MFC sequences were similar. However, the highest air resistance was obtained by GCC-c-starch-MFC sequence. The highest tear index was obtained by GCC-MFC-c-starch sequence, and the lowest tear index was obtained from GCC-c-starch sequence. It was found that GCC-MFC composite filler is helpful to improve the strength properties except for tear index.
