This research investigated the effect of the size of nano fibers from the fiber spinning process with electric static. The experimental procedure to change the distance between the tip of the needle and the scene, 15 10 supports 5,, and 20 cm. Concentration of polyvinyl alcohol 10 percent by weight, volume, the electric potential 15 kV and the time used in the experiment 6 minutes. Display the size of nano fibers from the electrospinning technique of micro mobile camera รศน์ electron microscopy Considering the effect of the distance between the needle tip with the support when concentrated polyvinyl alcohol. The electric potential and the time used in the experiment were fixed. It was found that the fiber is a different size that 5 cm. Fiber is the uneven, there are relatively large 10 cm. The fiber has a small line arranged together regularly 15 cm. Fiber is the uneven. The fibers are both large and small, together, support 20 cm fiber is the uneven. The fibers are both large and small, together. The distance between the needle tip to accommodate higher scene will help stretch of fibers. However, when the distance between the tip of the needle and the scene for much higher, it will make the appearance of the fibers bigger. Because of the distance between the needle tip to the scene to support related to voltage.
