To address the issue of low yield in the preparation of nanofiber materials using single-needle electrospinning technology, multi-needle electrospinning technology has emerged as a crucial solution for mass production. However, the mutual interference of multiple electric fields between the needles can cause significant randomness in the morphology of the produced nanofibers. To better predict the influence of electric field distribution on nanofiber morphology, simulation analysis of the multi-needle arrangement was conducted using finite element analysis (FEA) software. Nanofiber-coated yarn was produced continuously with the core yarn rotating. The water bath was utilized as the receiver of nanofibers on self-made water bath electrospinning equipment. The electric field distribution and mutual interference under seven different needle arrangements was simulated and analyzed by FEA software ANSYS Maxwell. The results indicated that when the needles were arranged diagonally in a staggered pattern and directly above the core yarn, the simulated electric field distribution was relatively uniform, with less mutual interference. The produced nanofibers exhibited a finer diameter and the diameter distribution was more concentrated. In addition, the nanofiber coating showed higher crystallinity and better mechanical properties.
为解决单针静电纺丝技术制备纳米纤维材料产量低的问题，多针静电纺丝技术已成为大规模生产的关键解决方案。然而，针之间多个电场的相互干扰会导致所生产纳米纤维形态出现显著随机性。为更好地预测电场分布对纳米纤维形态的影响，使用有限元分析（FEA）软件对多针排列进行了模拟分析。在芯纱旋转的情况下连续生产纳米纤维包覆纱。在自制的水浴静电纺丝设备上，将水浴用作纳米纤维的接收装置。通过FEA软件ANSYS Maxwell对七种不同针排列下的电场分布和相互干扰进行了模拟和分析。结果表明，当针以交错的对角线模式排列并位于芯纱正上方时，模拟的电场分布相对均匀，相互干扰较小。所生产的纳米纤维直径更细，直径分布更集中。此外，纳米纤维涂层表现出更高的结晶度和更好的机械性能。
