将聚合物纳米纤维静电纺丝到固定的接地目标上，可以产生一种非织造垫状材料。使用轮子或皮带形式的快速旋转的接地目标，可以生产出相当长的高度取向的电纺长丝纱线。当人们将电纺单丝的计算速度与接地目标的表面速度进行比较时，这种观察结果很难解释。这项研究就是试图回答这个问题。计算出的光纤速度正确吗？收集的电纺长丝真的是单丝吗？电纺长丝是否分裂成多根长丝，或者纤维是否在收集轮上以定向的方式成圈？波兰姆。英语。科学，47：1530-1535,2007。英国塑料工程师学会2007
Electrospinning of polymeric nanofibers onto a stationary grounded target produces a nonwoven mat-like material. Using a rapidly rotating grounded target in the form of a wheel or belt, it is possible to produce significant lengths of highly oriented yarns of electrospun filaments. This observation is difficult to explain when one compares the calculated velocity of an electrospun monofilament with the surface velocity of the grounded target. This study was undertaken to attempt to answer this question. Are the calculated fiber velocities correct? Is the collected electrospun filament really a monofilament? Does the electrospun filament split into multiple filaments or do fibers loop in an oriented manner on the collection wheel? POLYM. ENG. SCI., 47:1530–1535, 2007. © 2007 Society of Plastics Engineers
