Fibre Spinning with Axial and Radial Viscosity Distributions as Viscoelastic Flow with Dominating Extension

  • Stefan Zahorski


It is shown that non-isothermal melt spinning with axial and radial viscosity distributions can be considered as a particular case of the flows with dominating extensions discussed elsewhere. The governing equations are solved for weak variability of the extensional viscosity function with respect to the extension rate. Validity of the so-called quasi-elongational approximation, widely used in numerous references, is justified, and possibility of any “skin-effects” excluded.
