Abstract: In order to efficiently prepare high quality fiber membrane,a new type of needle roller differential electrospinning device was designed.The effect of spinning solution concentration and the needle piece spacing on fiber diameter distribution and fiber productivity were examined by taking PVA as a model polymer.The results showed that with the increase in the concentration of spinning solution (8wt%～11wt%),the average diameter of fibers was larger and the range of diameter distribution was wider.The electric field intensity distribution at the tip of the needle piece was mainly affected by the spacing of needle piece.With the increase in the needle piece spacing,the uniformity of electric field intensity distribution at each tip of needle piece were obviously improved,and the range of fiber diameter distribution was narrower.When the needle piece spacing was 10mm,spinning solution concentration was 8wt%,the fiber diameter was (161±67)nm.The fiber productivity increased with the increase in the concentration of spinning solution.The maximum spinning efficiency was 12.8g/h when the needle piece spacing was 10mm and the spinning solution concentration was 11wt%.
