The spinline behavior during electro spinning process was observed using high speed expose photography and line-laser scattering. The spinline was rotated with high speed around the nozzle after it was spun from the nozzle. Also it moved toward to the collecting plate at the same time. It resulted that the total spinline became similar to a bell shape having empty room inside. The electropsinning processing parameters such as concentration, applied voltage, air pressure and TCD showed significant influences on the spinline behavior.
