A non-linear integral constitutive equation, finite-element discretization and Newton iteration were used to analyse the fibre spinning process of viscoelastic liquid. The process was set up and studied in two ways: as an initial value problem which required the drawing force to be specified, and as a two-point boundary problem which required the draw ratio to be specified. Solutions were attained up to high elasticity, high draw ratio and large drawing force. The results were in agreement with available experimental data on the spinning of low-density polyethylene at 150 degrees C and polystyrene melt at 170 degrees C, with existing numerical solutions in the limiting case of the upper-convected Maxwell liquid, and with the analytic asymptotic solution for Newtonian liquid.
