Abstract: The present invention provides for method for spinning a reinforced cellulosic fibre or filament, comprising the steps of a. at a first point in time, forming a composite spinning solution comprising a first reinforcing particle, a cellulosic base material and a process solvent, and b. at a second point in time, extruding the spinning solution through an orifice into a regeneration fluid such as to form the reinforced cellulosic fibre or filament, wherein the composite spinning solution is formed by dissolving the cellulosic base material in the process solvent and distributively dispersing the first reinforcing particle in the process solvent.
