Summary The use of ionic liquid solvents for thespinning of regenerated cellulose fibres has thepotential to produce both technical and textile graderegenerated cellulose fibres. When spinning fibres,many parameters impact the material properties of thespun fibre. In this study, key wet spinning parametershave been investigated for the development of regeneratedcellulose fibres from ionic liquid solutions. Thecoagulation and associated diffusion equilibrium werecalculated for two imidazolium-based ILs, and it wasfound that the anion largely influenced the coagulationkinetics. This was likely due to the associationbetween the anion of the IL and cellulose. Theorientation of the polymer chains is known to influencethe mechanical properties greatly; previously, hotstretching was used to orientate cellulose acetate. Herewe investigated this influence on the mechanicalproperties of regenerated cellulose fibres by applying apost stretch at different stretch ratios.
