Melt spinning structure-property relationship

The detailed proof of this conceptual model is difficult experimentally, although it is generally supported by the existing experimental data and melt spinning process model. The overall veracity of the model is less important than the utility of the model in predicting process-structure-property relationships. Important implications of the model are as follows ... 

The effect of the molecular weight of the PPS and parameters adjusted in the melt spinning process on the properties of the final fibers have been elucidated. Structure-property-relationships were established by the use of tensile testing, differential scanning calorimetry, polarized light optical microscopy, and wide-angle X-ray scattering. 

Melt spinning is not limited to the production of conventional polymeric filaments various developments in terms of type of filaments, structure-property relationships, introduction of nano materials, and advances in process characterization have evolved in the last few years. Some of these developments are briefly discussed below.
