Abstract: The electrospinning and drawing of polymer solution into fibers is simulated using the bead-chain model.The diameters of fibers electrospun under different process conditions are obtained by computing the dynamic variations of the thickness of the polymer jet.PVA solution is spun on a pilot electrospinning apparatus to investigate the effect of the collection distance on the fiber diameter.The fiber diameter decreases as the collection distance increases from 14 cm to 40 cm.The results indicate that the experimental data agree with the simulation values when the collection distance is shorter than 30 cm.
