The effect of coagulation conditions on the morphology of as-spun PVC fibers from wet-spinning was studied with two different coagulant system ($H_2O$/DMF and $H_2O$/MeOH). The morphology of as-spun fibers spun into $H_2O$/DMF became denser but more unsymmetrical in shape with increasing DMF concentration up to 40%. However, the maximum draw ratio, $DR_{max}$, of such as-spun fibers was too low to produce a PVC fiber successfully. On the other hand, the morphology of as-spun fibers spun into $H_2O$/MeOH changed from circular to kidney bean shape with less voids and their $DR_{max}$ also increased with increasing MeOH concentration. $H_2O$/MeOH=20/80 coagulant bath system was suitable for the production of better quality PVC fiber having a denser circular morphology and a high $DR_{max}$ resulted in stronger tensile strength.
