【Abstract】 In this paper the mathematical model of PET molt spinning process using multihole spinnerets is presented. By means of this model the V, T, F, velocity gradient,solidification distance, tensile stress and birefringence along spinning path in each fiber layer can be obtained and the results computed are in agreement with the data measured.更多还原
