Model to Predict Polymer Fibre Diameter during Melt Spinning

Polymeric materials were evaluated with regard to their spinnability and respective fibre diameters. A modified single spinning device was firstly used derive a novel generalised model, utilising process parameters (die diameter, throughput, stretching relevant take-up pressures) material properties (zero shear viscosity) predict the diameter of polymeric fibres on basis four different polymers. Further evaluation resulting power law dependence conducted filaments produced via conventional melt meltblown processes. Fibres pilot machines showed close agreement model equation only need adjust an easily calculable dependent factor. The outcome presented work is user-friendly high practical relevance, which can be amorphous semicrystalline fibres, independent machine sufficient accuracy for fast estimations.
