A micromechanical model of non-isothermal flow-induced crystallization of rod-like molecules in high-speed extrusion spinning is proposed. This model shows that a necking zone on a fibre may be switched on by the flow-induced crystallization of rod-like molecules. Crystallization and necking depend strongly on the values of polymer parameters characterizing its microstructure. The appearance of necking in some specific ranges of winding speeds may be characteristic only of some specific types of rod-like molecules. The rate of crystallization in a spinline is practically unaffected by an increase in winding speed beyond 2000-3000m/min.
