An elementary framework to describe the evolution of orientational order in melt spinning of polymers is presented. By dividing this process into fundamentally different zones of structure development (melt zone with T > temperature of initiation of crystallization T c ; crystallization zone with T c > T > T g ; static zone with T < T g ), it is shown that a generalized framework can be developed into which different homopolymers can be fitted on the basis of their physical transition temperatures. Sources of deviation from the simplified framework are also discussed.
