Method for application of liquid polymeric material onto spinning cords and a device for production of nanofibers through electrostatic spinning

摘要

The present invention relates to a method and apparatus for applying a liquid polymer material to an active spinning zone of a cord (2) of a spinning member of a spinning electrode by application means, said application means comprising at least one spinning electrode Moves reversibly along the active spinning zone of the cord (2) in an apparatus for the production of nanofibres through electrostatic spinning of liquid material in an electrostatic field with high intensity between oppositely disposed collecting electrodes.Characterized in that the liquid polymer material is applied to the cord (2) about the entire circumference of the cord (2) without any contact with the gaseous environment in the spinning space and the application means (6) The thickness of the layer of liquid polymeric material is reduced while leaving the application means 6 and the electrostatic spinning process of the liquid polymeric material applied to the cord 2 immediately after leaving the application means 6 It starts.
