EXTRACTION OF NANOFIBRILLATED CELLULOSE FROM KELEMPAYAN (<em>NEOLAMARCKIA</em> <em>CADAMBA</em>) AND ITS USE AS STRENGTH ADDITIVE IN PAPERMAKING

Abstract

Nanofibrillated cellulose (NFC) is a cellulose at nanoscale dimension that can offer multitude applications in various industrial sectors such as pulp and paper, composite, cosmetic, pharmaceutical and others. In this study, NFC was prepared from bleached kelempayan (Neolamarckia cadamba) pulp. The resulting NFC was added into laboratory handsheets (60 g m^-2) at 2, 4, 6, 8 and 10% of addition level. The results showed that incorporation of NFC in papermaking enhanced the strength in tensile, burst and fold with increasing dosage but exhibited reduction in tear and air permeability as more NFC was added.
