Enhancing strength properties of recycled paper with TEMPO-oxidized nanocellulose

Recycled fibers used in the manufacturing of paper and board are associated with strength deficiencies. This study investigated use TEMPO-oxidized nanocellulose from oil palm empty fruit bunch (OPEFB-TEMPO) for reinforcing papers made such fibers. Strength properties tensile tear were enhanced addition OPEFB-TEMPO, strong correlations, as indicated by R2 values. The reinforcement capability was supported scattering coefficient-percent relationship. only drawback is that it reduces pulp drainability, which can be minimized adding drainage aids. Because a relatively small amount required, OPEFB-TEMPO has potential to strengthening agent, particularly production low grammage papers.
