Description

technical field [0001] The invention relates to a centrifugal coaxial electrostatic spinning machine, which belongs to the field of electrostatic spinning and the field of machinery. Background technique [0002] Electrospinning is a method of preparing micro-nano fibers by using the drawing effect of electrostatic force on polymer jets. According to the different spinning media, electrospinning is divided into solution electrospinning and melt electrospinning. Traditional melt or solution electrospinning has relatively low spinning efficiency. Centrifugal spinning is a method of using centrifugal force to throw polymer jets out to prepare micro-nano fibers. Although centrifugal spinning improves the output of fibers to a certain extent, due to the thicker fibers prepared, the diameter distribution is not uniform. applications of nanofibers. By combining with electrospinning and improving centrifugal spinning, a centrifugal electrospinning technology is obtained, which ov...
