Fibres and films were formed from mesophase solutions of cellulose in ammonia/ammonium thiocyanate solvent. The physical properties of the fibres and films were discussed on the basis of the properties of the mesophase solutions used. Cholesteric and nematic phases were formed in the solutions. Fibres were extruded from both kinds of solution. The fibres from the nematic solutions were more highly oriented, had a more fibrillar texture and were apparently stiffer than those from the cholesteric solutions. The fibres spun from the nematic solutions using the technique of dry jet-wet spinning had moduli comparable to those of Fortisan ~.
