Continuous nanofiber yarns were prepared using the electro-blown and hanging yarn process. Unlike typical electrospinning devices, this method uniquely controls the spinning process to induce the hanging phenomenon, and the resulting hanging yarn is twisted to form nanofiber yarns. A polyvinylidene fluoride nanofiber yarn was successfully prepared using the electro-blown and hanging yarn process. Scanning electron microscopy observations confirmed that the nanofibers prepared by this method exhibited good orientation within the yarn. The results indicate that the conductivity of the polymer solution and the applied voltage are crucial for inducing the hanging yarn process, ensuring stable continuous spinning. A possible mechanism is proposed, suggesting that adjusting the solution’s conductivity and controlling the spinning voltage can utilize defects in the yarn-hanging process during spinning to prepare nanofiber yarns.
