Abstract This Thesis predict a relation between needle and needle-less electrospinning ,as the needle-less or roller electrospinning is a time consuming and expensive procedure .so Poly (ethylene oxide ) with different molecular weight ,concentration and additives was tested on needle and needle-less elctrospinning with changing solution and process parameters (Molecular weight,voltage supply ,distance between electrodes, addition of NaCl-salt) whereas the ambient parameters (temperature and humidity )were kept constant. The results were examined on SEM and shows a great relationship between needle and needle-less electrospinning particularly in terms of spinnability,fiber quality ,non-fiborous area ,fiber diameter, fiber diameter distribution and throughput. The result are usefull in predicting the behavior of polymers in needle-less electrospinning with results from needle electrospinning.
