Using Cellulose Nanofibrils (CNF) for the production of filaments is a comparatively new application for CNF which can broaden nanocellulose applications in many ways. Nanocellulose filaments can be used to make textiles and thus can be used in the composite structures as well as high-tech textile and clothing applications. Different methods are proposed for spinning of filaments from cellulose nanofibrils which are mostly under two categories of dry-spinning and wet-spinning. In the dry-spinning method, the substrate will have significant influence on the properties of the filament as the as-spun filament will be firstly in contact with the substrate. In this work, the influence of different substrates on the properties of the nanocellulose filament is studied. Teflon tape, Teflon film and glass are used for this study and the influence of adding oil to decrease surface friction on the surface properties of the substrate were studied. The relationships between surface properties and the cross-sectional form of the filaments are evaluated.
