The low production rate of electrospinning process may limit the industrial use of single needle system. Multiple needles can be used to improve the throughput. But the jets bend outward because adjacent electric fields interfere with one another. In this paper, the electric field was analyzed by electromagnetic analysis software. The influence of needle distance on electric field interference and jets' bending was investigated. The results indicate that the incline of electric field direction near the needles is the major factor of jet's incline.
