Abstract

Draw resonance instability in a bicomponent fiber spinning flow is investigated using a model in which a Newtonian and an upper-convected Maxwell fluid are the core and skin layers, respectively. This model is to consider a situation where the two fluids have very different extensional rheology. The results indicate a significant influence of the viscoelastic skin layer on the overall flow mechanics even when its relative flow rate is small. It is also predicted that under certain conditions the stability of the bicomponent fiber can be maintained to a higher draw ratio than obtainable with either fluids individually.
