Abstract

The melt spinning process for artificial fibers has been studied by many research groups throughout the world during the last four decades. However, comparison of flow-induced crystallization melt spinning processes has not yet been treated in the literature. In this study, we analyse the dynamics of the flow induced crystallization melt spinning process. Further, we study the sensitivity of the process with respect to fluid shear modulus. Non-Newtonian and Maxwell-Oldroyd models are used to describe the rheology of the polymer the fiber is made of. It has been found that the flow-induced crystallization Maxwell-Oldroyd model has an upper bound for the final velocity.
