Doctoral Dissertations
A mathematical model was developed to describe the high speed melt spinning behavior of nylon-6. This model is based on the equations of continuity, momentum and energy. These equations are combined with a Newtonian model for rheology to describe the process dynamics and models for the development of birefringence, molecular orientation and crystallization kinetics to describe the structure formation during high speed melt spinning of nylon-6. Physical property relationships from the literature are input and used together with the processing conditions to calculate velocity, diameter, temperature, stress, birefringence and crystallinity profiles along the spinline.
