Methods and apparatuses are provided for producing fibers via electroblowing. In an embodiment of the present invention, a polymer stream, formed from a spinning nozzle, passes through a first temperature zone for a first residence time, and subsequently passes through a second temperature zone for a second residence time, where the second zone has a higher average temperature than the first zone. In an embodiment of an apparatus of the present invention, the apparatus has a region between the spinning nozzle outlet and collector that includes at least two zones through which a polymer stream passes, where the second zone has a higher average temperature than the first zone. |
