High voltage at 20kV to 40kV will be applied to a spinneret and polymer solution jet will be injected to a collector when electrical attraction exceeds surface tension of polymer solutions.&nbsp; Solvents in jets are gradually volatilized and jets will reduce to nanometer level when they reach a collector.
