Experimental Study on Falling Process of Melt Electrospinning Fiber

摘要

As one directly method to produce nanofibers, electrospinning has been studied extensively. However, the buckling phenomenon is not understood completely especially to the process of melt electrospinning. The authors carried out a series of experimental study on this phenomenon with high speed video. This is the first article of the research, in which we defined three stages to the whole spinning process according to the time. The specialties of each stage were list out. The falling process was divided into straight-line movement, spiral swinging, and deposits on the collector three sections. The buckling reasons were provided.
