摘要： The present invention relates to an electrospinning apparatus comprising a spinning tube having a plurality of spouting holes, in which the spinning tube which is rotatable and having a plurality of spouting holes instead of conventional nozzles is employed as means for electrospinning a spinning solution in the direction of a collector. According to the present invention, electrospinning is performed using both electrostatic force and centrifugal force, thereby increasing discharge amount of unit polygonal tube per unit time and thus significantly improving productivity. Compared to conventional electrospinning apparatuses that use nozzles, the necessity of replacing and cleaning nozzles is eliminated and production processes are thus simplified. As the collector is located above the spinning tube having the plurality of spouting holes, a phenomenon (drop phenomenon) in which the spinning solution in a solution state not a fibrous state drops onto the collector during electrospinning is prevented to improve the quality of the nanofiber web being produced.
摘要翻译：本发明涉及一种电纺丝装置，其特征在于，包括：具有多个喷出孔的纺丝管，其中可旋转的纺丝管和代替常规喷嘴的多个喷射孔用作将纺丝溶液沿着方向静电纺丝的装置的收藏家根据本发明，使用静电力和离心力两者进行静电纺丝，从而增加单位时间的单位多边形管的排出量，从而显着提高生产率。与使用喷嘴的常规静电纺丝装置相比，消除了更换和清洁喷嘴的必要性，从而简化了生产工艺。当收集器位于具有多个喷射孔的纺丝管上方时，防止了在静电纺丝期间溶液状态不纤维状态的纺丝溶液滴落到收集器上的现象（下落现象），以提高纳米纤维的质量正在生产网页。
