静电纺丝和熔喷是生产微纤维非织造布最常用的工艺。在本文中，我们研究了多针系统的静电纺丝大规模生产。为了在高生产率下获得均匀的纤维，使用了一个辅助板电极连接到三针系统以获得更均匀的电场。对具有两种针阵列（线性三针和三角形三针）的喷丝头进行了研究。静电纺丝实验和电场模拟的结果表明，带有辅助板的多针喷丝头能够生产出更细且更均匀的纳米纤维。并且有辅助板时纤维能够在更集中的区域收集。我们还关注了突出在板外的针长度的影响。这项研究表明，通过设计电场分布，我们有可能在高生产率下生产出更细的纤维以及更集中的收集垫。
Electrospinning and melt blowing are the most commonly used processes for producing microfibrous nonwovens. In this paper, we study mass production of electrospinning with a multineedle system. To achieve uniform fibers at a high production rate, an auxiliary plate electrode has been used to be connected to a three-needle system to obtain a more uniform electric field. The spinnerets with two kinds of needle array, linear three-needle and triangular three-needle, are studied. The results of electrospinning experiments and electric field simulation demonstrate that the multineedle spinneret with an auxiliary plate can produce finer and more uniform nanofibers. And the fibers can be collected in a more concentrated area with the auxiliary plate. We also focus on the effect of the needle length protruded outside the plate. This study shows a possibility that by designing the electric field distribution, we can produce thinner fibers and more concentrated collection mats at a high production rate.
