Abstract: This paper presents a new process to fabricate single polyvinyl alcohol (PVA)/nanofibrillated cellulose (NFC) filaments and measures their tensile properties at various NFC ratios (0.5 to 3 wt %). The fabrication process generally contains four steps: (1) NFC isolation, (2) pre-paration of the PVA/NFC solution, (3) gel spinning and drying, and (4) filament stretching. The ultimate strength of PVA/NFC increased by almost 2 times compared with stretched neat PVA filaments. In order to ensure that the NFC fibers dispersed well in the PVA solution, high shear processing was employed. To study the possible degrada-tion of PVA caused by high shear, a parallel plate rheo-meter was used to investigate the viscosity of the PVA/ NFC solutions. The PVA crystal orientation in the PVA/ NFC filaments was characterized by wide angle x-ray diffraction (WAXD).
