Abstract
The present invention relates to a process for producing high tensile strength nanofiber yarn by wet-extrusion on a slippery surface. In particular, the present invention discloses a method wherein individual nanocellulose fibers are aligned by high speed in-nozzle-alignment and on-surface-alignment, which comprise controlling the fiber width on a moving slippery surface.
