Popis:	The major concern on this study is the possibilities of polymer solution being continuous fiber form or separate small polymer bid form under the high electric field. Former case is the electrospinning and latter is the electrospraying. A formability model for electrospinning is suggested considering physical properties of the polymer solution and process parameters. This formability model is developed to predict onset of electrospinning. Formability is based on spinnability theories of C. D. Han and Ziabicki’s works. The results show that formability is determined by surface tension, viscosity of solution and radius of nozzle. The fiber diameters calculated through this newly developed formability model is presented and compared with the experimental data using electrospun PVP polymer solution.
