The performance of cationized pulp fiber as paper making wet-end additive
In this study, Cationic Pulp Fiber (CPF) was prepared using three levels of 0, 2, 4% (3-chloro-2-hydroxy propyl) trimethyl ammonium chloridein and three temperatures of 40, 60 and 80 °C. Then the CPF fibers were blended with virgin pulp fibers to make handsheets.The results showed that the effect of...

| Sumario: | In this study, Cationic Pulp Fiber (CPF) was prepared using three levels of 0, 2, 4% (3-chloro-2-hydroxy propyl) trimethyl ammonium chloridein and three temperatures of 40, 60 and 80 °C. Then the CPF fibers were blended with virgin pulp fibers to make handsheets.The results showed that the effect of temperature, CHTMA and CHTMA*temperature interaction on cationizing the fibers was statistically significant. Maximum absorption of cationic CHTMA on pulp fibers with the average of 53.33%was obtained by application of 2% CHTMA at 60 °C temperature. The mixture of 70% long fibers , 30% short fibers, 1% cationized pulp fiber, 5% PCC and three levels of C-PAM (0, 0.05 and 0.1%) was used to prepare handsheets. Freeness of blended pulp and mechanical properties of produced paper such as tensile index, tear index and burst index was determined. Statistical analysis of results showed that the effect of applied treatments was statistically significant. The highest freeness and mechanical properties obtained in different conditions were as follow; freeness (669 mlCSF): CPF 1%, C-PAM 0.05%, PCC 5%; tensile index (15.25 N.m/g): CPF 1%, C-PAM 0.1%, PCC 5%; tear index (12.3 mN.m2/g): CPF 1%, C-PAM 0.1%, PCC 5%; burst index (0.68 kPa.m2/g): CPF 1%, C-PAM 0.05%, PCC 5%. |
