Description

technical field [0001] The invention relates to the field of electrostatic spinning. More specifically, the present invention relates to continuous collection devices for electrospinning for use in situations where the solvent in the polymer solution is not volatile. Background technique [0002] Electrospinning is a special fiber manufacturing process. This method can produce polymer filaments with nanometer diameters. The basic principle can be simply summarized as the effect of electric field force on polymer solution or melt in a high-voltage electrostatic field. The jet spinning is carried out under the capillary or the end of the bubble to form a jet and fly to the receiving device. The general electrospinning device includes a high-voltage power supply, solution storage, spraying and receiving device, where the receiving device corresponds to the receiving of the fiber, and the jet reaches the receiving device. In the process of high stretching, the fibers become thi...

AI Technical Summary

Problems solved by technology

[0003] In the existing electrospinning device, when the solvent is not easily volatile, the solvent in the polymer solution is dissolved in the coagulation liquid in the water bath mainly through the docking of the water bath and the spraying device, so that the fibers are separated out. The shape and thickness of the fiber cannot be controlled. At the same time, the coagulation liquid in the water bath is a non-flowing fluid. After processing a part of the fiber, it is necessary to suspend the work of the electrospinning device and continue after replacing the coagulation liquid, so that the electrospinning work Discontinuous, unnecessary time wasted, and the coagulation rate will decrease after the coagulation solution in the water bath processes a part of the fibers, prolonging the coagulation time
