Abstract

The invention belongs to the technical field of electrostatic spinning, and discloses an electrostatic spinning device. The device comprises a propulsion mechanism, wherein the propulsion mechanism isused to feed a spinning solution stored inside an injector into a spray nozzle by controlling the movement of a piston core rod inside a syringe barrel of the injector, the spray nozzle is arranged on a spinneret slab, the spinneret slab is connected with a moving mechanism, the moving mechanism is used to control the spinneret slab to move in the axis direction of a winding roller and adjust thedistance between the spinneret slab and the winding roller, both ends of the winding roller are arranged on an adjusting mechanism, and the adjusting mechanism is used to adjust the height differencebetween the winding roller and the spinneret slab. The invention further discloses a spinning method of the electrostatic spinning device.

Description

technical field [0001] The invention relates to the technical field of electrostatic spinning, in particular to an electrostatic spinning device and a spinning method. Background technique [0002] Electrospinning is an electrohydrodynamic process in which droplets are charged to create a jet, which is then stretched and elongated to create fibers. During electrospinning, liquid is extruded from the spinneret plate due to surface tension, producing pendant droplets, which, when charged, are deformed into Taylor cones by electrostatic repulsion between like surface charges, from which they are ejected A charged jet, the jet initially extends in a straight line, then undergoes a violent stretching motion due to bending instability, as the jet stretches to a finer diameter, it solidifies rapidly, causing solid fibers to deposit on the grounded collector . Electrospinning technology, as a simple and effective new spinning processing method, plays a huge role in air purificatio...
