连续电纺纳米纤维自动调匀控制方法

Automatic Even Control Method for Continuous Electricity Spinning Nanofiber

目前在连续电纺纳米纤维的制备过程中,难以保证纤维直径的高均匀度,制备的纳米纤维在高性能场合应用需要进行第二道调匀工序。为了解决这一问题,通过建立纳米纤维收集辊运动控制模型,提出一种偏振误差补偿方法,有效解决了由纤维收集辊转动微偏震造成的纤维直径不均匀的问题,实现了纳米纤维的自动调匀,制备的纳米纤维直径均匀度达到99.9%。

At present during the fabrication process of continuous electricity spinning nanofiber,the fiber diameter high evenness is difficulty to guaranteed.When the prepared nanometer fiber is used in high performance occasions,the second process of even control is needed.In order to solve this problem,through establishing the motion control model of nanofiber collect roller,a kind of polarization vibrating error compensation method was put forward.The uneven problem of fiber diameter caused by small slant vibration of the fiber collect roiler was solved effectively.The automatic even control for nanofibre is realized,and the diameter evenness of prepared nanometer fiber reaches 99.9％.
