On the other hand , the collection on a rotating cylinder is helpful to the process of electrospinning , and it is furthersome to get the ordered mats , otherwise , because the velocity of cylinder rotating is far less than that of nanofiber depositing , the rotation of cylinder has not the function of drawing 另外,采用辊筒收集有利于纺丝工艺的顺利进行,而且辊筒收集能使纤维毡中的纤维较整齐排列,但辊筒的卷绕速度远远小于电纺丝速度,辊筒的旋转不能起到拉伸的作用。
