Abstract
A centrifugal spinning system and method for forming a fibrous web containing nanofibers, microfibers, or a combination thereof from a molten polymer composition or an aqueous spinning solution is provided. Through careful control over the arrangement of the system, a fibrous web can be formed that is relatively defect free. To help accomplish this feature, at least two centrifugal spinning chambers, each containing a charged forming plate, are utilized. To minimize the present of defects in the fibrous web, the charge applied to the first spinning chamber has a polarity that is opposite the polarity of the charge applied to the second spinning chamber.
