The micromechanical description of nonisothermal flow‐induced crystallization of a polymeric liquid with rodlike molecules is the main part of the fiber spinning model described here. Solutions of the governing equations show that an increase in winding velocity leads to the appearance of an on‐line flow‐induced crystallization zone in a fiber. This zone manifests itself in accelerated formation (necking) due to the release of heat of crystallization which results in the decrease of viscosity. Liquid crystallinity grows very rapidly in the necking region, which, in turn, leads to the growth of viscosity after some minimal value, which finally arrests fiber deformation.
