Influence of the auxiliary electrostatic gradient field on the fiber deposition area (setting 1) for a spinning time of 100 s: (a) Uaux = −5 kV, (b) Uaux = −10 kV. (c) Superposition of spinning on the target from experiment (b) with auxiliary electrodes turned at 30° and 60°, at Uaux = − 10 kV. The scale bar is 1 cm for all images.
