Abstract A study of fibre spinning using an equation of state which accounts for the finite extensibility of the macromolecule is described. The results in this study show the birefringence to increase in a less than linear fashion with spinning stress, which is in agreement with experimental data. Previous studies use equations of state which allow the macromolecule to extend infinitely and therefore predict birefringence to increase linearly with the spinning stress. Accounting for the finite extensibility allows the simulation to be performed at higher throughputs which are more representative of those encoutered in industry. Draw ratios are predicted which are greater than the limit imposed by the infinitely extensible macromolecule model.
