  Abstract

This research investigates the formation progression of fi bers with beaded and grooved structures, as well as the eff ect of electric fi eld on jet motion and fi ber morphology for three circumstances: no auxiliary electrode, 12 kV auxiliary electrode, and 18 kV auxiliary electrode. The observations discover that adding auxiliary electrode and modifying the voltage of the auxiliary electrode can infl uence the electric fi eld in the jet area, aff ecting the fi ber morphology. The auxiliary electrode with 12 kV voltage provides a uniformly distributed strong electric fi eld in the jet area which can balance the jet's surface tension, generating bead-free fi bers with a grooved structure on the surface. An increase of auxiliary voltage to 18 kV induces the linear section of the jet to enlarge, the whipping zone to narrow, and the instability of the jet, resulting in the reappear of the beaded structure as in the case without the addition of an auxiliary electrode. This research indicates that optimizing the electric fi eld produces more delicate fi bers and enhance fi ber collection at a high production rate. Furthermore, the inhomogeneous and unstable electric fi eld during the spinning process causes the fi bers to develop a hierarchical structure.
