Abstract

Abstract: Jet whip is the main mechanical factor of fiber becoming nano-scale fiber, and its stability largely determines the stability and quality of spinning. This article analyzes the complex relationship of various forces on the jet, analyzes the motion process of the steady-state jet based on the conservation of momentum, establishes the controls equations, and analyzes the effect of the electrostatic field on the steady-state jet motion. Combining the finite element analysis software COMSOL Multiphysics 5.0 to optimize the electric field. A method space insulator method that is enhanced spatial electric field strength to suppress jet whip is proposed. By introducing a polar polymer as an electrode to enhance the field strength in the space region, the electric field force of the moving jet can be enhanced to eliminate the coupling of other forces other than the electric field force, and the effect of suppressing the unstable whip of the jet is enhanced and improved. The stability and quality of electrospinning is improved.
