Interest in near-field electrospinning for high-precision positioning in additional material manufacturing has expanded in recent years. In order to increase the high-precision production rate, a methodology has been proposed to add the number of jets by using nozzle arrays in near-field electrospinning. To define the mutual influence of the jets, deposition characteristics of the double-nozzle near-field electrospinning have been observed. This paper described the work and results of the experimental investigation and the theoretical derivation. Experimentally, such effects are demonstrated through use of a 4 % polyethylene oxide solution. The deposition rule of double nozzle near-field electrospinning has been learned in accordance with Coulomb's law. Experimental results showed that the mutual distance of the deposition becomes larger with increases in the voltage, needle spacing, and working distance. Theoretical derivation based on the net electric field environment has been studied to verify accuracy of the experimental conclusion.
