Abstract: In general, two jets bend outward because adjacent electric fields interfere with the other in the double-needle electrospinning process. Therefore, the continuity of electrospinning process and the evenness of fiber web decrease. This paper focuses on dual-nozzle electrospinning device, and two in the spinning process the fiber spray nozzle with the same charge as the mutually exclusive, exacerbated the instability of the jet, making the fiber web distribution uneven. On this basis, we designed a variety of auxiliary electrodes to stabilize the jet, uniform fiber network. By Ansoft Maxwell 3D electromagnetic field analysis software for modeling and analysis to explain why the auxiliary electrode can play such a role for the further development of electrospinning.
