Abstract

Employing the same kinematic wave theory used in the previous paper on Newtonian fluids (Part I), draw resonance in isothermal spinning is solved analytically for both power law and Maxwell fluids. The critical drawdown ratios at the onset of draw resonance are again found by equating twice the throughput wave residence time to the thread-line residence time yielding the same results reported by others through numerical calculations (Pearson and Shah, 1974; Fisher and Denn, 1976), thus confirming the premise that draw resonance is the result of the propagation of throughput waves.
