In this study, I have investigated the effect of Sodium Chloride (NaCl) salt on the spinnability of Polyethylene oxide (PEO) nanofibers and electrical current which is carried on jets via roller (needleless) electrospinning method. At first, solution properties were determined and then the results were analyzed. According to results, NaCl salt concentration has an important effect on conductivity, viscosity, spinning performance, fiber diameter and morphology. Conductivity and diameter of fibers increase with salt concentration. Polyethylene oxide with 0,3wt% NaCl gives the best spinning performance (throughput). During spinning process, process was recorded by camera and electrical current has been measured, afterwards, current, which was carried through per a jet was calculated. Eventually fabric throughput per current carried by Taylor cone was extrapolated.
