Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a central point electrode electrostatic spinning device and a spinning method. Background technique [0002] Electrospinning technology is a method of using high-voltage static electricity to make polymer melt or solution into fibers, and the required equipment is simple. It is currently one of the most important methods for preparing polymer nanofibers. The traditional solution electrospinning device is that the capillary needle is connected to the high-voltage electrode, and the receiving plate is grounded. Melt electrospinning needs to be heated to maintain the melt temperature, and a heating device needs to be added. The spinning nozzle is grounded, and the receiving plate is connected to the high-voltage electrode. Reverse connection method . In these two wiring methods, the high-voltage electrode and the ground electrode are located on both sides, and the receiving device m...

AI Technical Summary

Problems solved by technology

In these two wiring methods, the high-voltage electrode and the ground electrode are located on both sides, and the receiving device must be connected to the electrode, which greatly limits the choice of the receiving device, especially the form of the receiving device connected to the high-voltage electrode, which requires the receiving device to be connected to high-voltage static electricity. Higher requirements are put forward for the insulation of equipment, and it is difficult to realize the method of roller receiving, etc., and it is impossible to realize fiber deposition and spraying on the surface of any object, which limits the application of electrospinning
