high voltage was then applied between the polymer solution 203 and the collector 206 to form a plurality of polymer jets on the top surface of the discs 212 the formation of jets filaments was found to be mainly influenced by the applied voltage and the polymer concentration of the polymer solution 203 a spinneret 218 can also include more than one tubular coil to increase the productivity of the electrospinning apparatus a two coil setup is illustrated in fig2 the illustrated spinneret 218 includes two tubular coils 220 221 each mounted on a separate central axle 222 223 the central axles 222 223 are radially spaced apart by a distance of from the coil radius to 10 times of the coil radius the coils can rotate either in the same direction or opposite direction this spinneret 218 operates in an electrospinning apparatus in a similar manner as described for a single coil spinneret 12 in relation to the electrospinning apparatus 10 shown in fig1 and 2 the basic spinneret 230 air flow setup is illustrated in fig2 this spinneret 230 operates in a spinneret 218 in an electrospinning apparatus in a similar manner as described for the disc spinneret 114 in the electrospinning.
