Sensitivity of Viscoelastic Melt Spinning Processes with respect to Operation Conditions and Material Constants

Abstract

The sensitivity of the viscoelastic melt spinning process with respect to parameters has not been reported yet in the literature. The study on the sensitivity of the melt spinning process is quite important industrially because it is closely connected with the subject of productivity and product quality of the industrial process. In this study, we investigated sensitivity of the viscoelastic melt spinning process with respect to the velocity and temperature of the quench air, fiber length and the fluid characteristic relaxation time. Maxwell-Oldroyd model is used to describe the rheology of the polymeric materials. It has been found that the quality of the final product depends on the values of the parameters. Further, we have found that it is not possible to change the parameters arbitrary because it may yield irregular fiber or induce breakage of the individual filaments of the spinline.
