The dynamics and heat transfer on the spinning line during the air drawing process are discussed in detail, mainly relating the forces acting upon the polymer along the spinning line and the expressions of the air drawing coefficient C〓 and heat transfer coefficient h. By introducing the power-law model as the constitutive equation to describe the theological properties of polymer melt and considering the changing of the density and specific heat capacity of polymer melt at constant pressure with the polymer temperature, the former model of polymer air drawing is improved and a complete polymer air drawing model is established, which is integrated with the model of air jet flow field of dual slot die.
