用静电纺丝法从丙烯酸树脂的二甲基甲酰胺（DMF）溶液中纺出直径小于1 μ的纤维。高速摄影显示，从悬浮在金属毛细管上的带电液滴中拉出了一根纤维。计算表明，旋转速度可能达到甚至超过空气中的声速。电场图和其他理论研究表明，导电性在纺丝机制中起着重要作用。确定了溶液粘度、周围气体、流速、电压和几何形状对纤维直径和射流长度的影响。
Fibers measuring less than 1 μ in diameter were spun by electrostatic means from dimethyl formamide (DMF) solutions of acrylic resin. High-speed photographs showed that a single fiber was drawn out from the electrically charged drop which was suspended from a metal capillary. Calculations indicated that spinning velocity probably reached and perhaps exceeded the velocity of sound in air. Electric field maps and other theoretical considerations showed that electric conductivity plays an important role in the spinning mechanism. The effects on fiber diameter and jet length of solution viscosity, surrounding gas, flow rate, voltage, and geometry were determined.
