Abstract
This research was carried out to study the influence of acetylation on paper dimensional stability. Specimens from printing paper and Texon paperboard were oven dried and then treated with acetic anhydride at 120°c for 30 and 60 min without catalyst. Acetylated papers were soaked in water for 2 and 24 h. Afterwards, bulking effect of the acetylation and thickness swelling of the specimens as well as anti-swelling-effect (ASE) were determined in the treated specimens.
Results revealed that the bulking of the specimens were increased by reaction time. However, in case of Texon, it was slowed down after 30 min of the reaction time. The thickness swelling of the treated specimens was significantly reduced after soaking in water for 2 and 24 h compared with untreated samples. As it was expected the acetylation increased ASE in Texon and the printing papers.
