Abstract

New strategy to determine the draw resonance instability using the frequency response method, first devised by Kase and Araki1) has been developed in the spinning process considering the viscoelastic nature of polymer melts. Numerical technique for efficiently evaluating the complex-valued frequency response system has been revamped in this study. By adopting the Nyquist stability criterion into frequency response, stability windows of the viscoelastic spinning system have been successfully predicted in both isothermal and nonisothermal cases. This stability-determining method as a useful analysis tool can be applied equally well to other extensional deformation processes.
