Effect of Viscosity Ratio of Two Immiscible Polymers on Morphology in Bicomponent Melt Spinning Fibers

Bicomponent fibers were melt spun to investigate the effect of individual component viscosity on the cross section morphology. Two couples were tested, polypropylene MFI 18 (PP18) with polyamide 6 (PA6) and, polypropylene MFI 25 (PP25) with polyamide 6 (PA6). Viscosity versus shear rates was evaluat...
