| Abstract: |
| In this study, bulky paper was prepared by adding bulking promoters. The tensile strength of all handsheets decreased with the reduction of sheet density, decrease of the tensile strength of acidic handsheets was more significant than that of the neutralized handsheets. The Page equation was used to evaluate the contributions of single fiber and interfiber bond to tensile strength of the handsheet. As a result, the tensile strength of the handsheet decreased with the decrease of interfiber bond strength. The scattering coefficient of the handsheet increased with the reduction of paper strength. Improvement of sheet thickness was confirmed by the SEM observation. |
