| Outline of Final Research Achievements |
In this study, we attempted to develop low density paper with high mechanical strength. We changed the morphology and the size of recycled pulp fiber using the aqueous counter collision (ACC) method. Thereafter, fiber sheets were prepared from the modified recycled pulp fiber. These sheets exhibited higher strength and lower density under the same ACC treatment condition, compared to sheets made from modified virgin pulp fiber. Furthermore, pulp sheets mixed with cellulose nanofibers (CNFs) made from recycled pulp fiber tend to have a similar strength and lower density to the pulp fiber sheets mixed with CNFs made from virgin pulp fiber.
