Modelling and numerical simulation of the polymeric extrusion process in textile products

Paola Francesca Antonietti, Nur Aiman Fadel, Marco Verani


We present the mathematical modelling and the numerical simulation of the polymer extrusion process of hollow and non-hollow yarns. In particular, the polymeric material flow has been modelled as non-Newtonian, incompressible, isothermal and steady. We attempt to develop a possible strategy for effective die design in profile extrusion and we numerically asses the validity of the model on both academic and real industrial test cases.
