摘要：AbstractElectrospinning is a new type of free-end spinning built on the electric field. The electric force of PAN polymer solution overcomes the surface tension of the solution, and then it causes wave and forms jet flow. In the process of injection, the solution is evaporated or solidified, and eventually forming a fiber on the receiving device. Different from ordinary single needle head, in this study, a new type of three-dimension free surface nozzle is used to produce multiple jets at the same time, this will greatly improve production efficiency. In this paper the model of three-dimension free surface is analyzed by the theory of fluid mechanics, the relationship among the wave length and surface tension and the electric field is obtained. Through the experiment, the conclusion is verified, and the formula is correct.
