Summary: | An apparatus for continuous needleless electrospinning of a nanoscale or submicron scale polymer fiber web onto a substrate includes an electrospinning enclosure that includes at least one liquid polymer coating device and an electro spinning zone and a wire drive system located external to the electro spinning enclosure. The wire drive system drives a plurality of continuous electrode wires through the electrospinning enclosure. A liquid polymer recycle and feed system is located external to the electrospinning enclosure and includes a recycle and feed tank that supplies liquid polymer to and receives overflow liquid polymer from the at least one liquid polymer coating device. A vapor collection and solvent recovery system includes at least one exhaust stream, collects and processes vapors generated in the electrospinning enclosure, and maintains a pressure in the electrospinning enclosure that is lower than atmospheric pressure. |
