A mathematical model of the melt spinning process that includes crystallization has been used to compute the velocity, diameter, temperature, and birefringence as a function of distance from the spinneret. An improved inversion procedure is described and is shown to give better results for the computed apparent elongational viscosity and heat‐transfer coefficient data. The computed profiles have been compared directly to the experimental profiles determined earlier and reported in Part I of this paper. The results show that the model describes the major features of the melt spinning process. The reasons for the observed differences between experimental profiles and those computed from the model are discussed.
