Abstract

The invention relates to the technical field of textile equipment and discloses an electrostatic spinning device. The electrostatic spinning device comprises an electrostatic generator, a spinneret box and N spinneret modules detachably arranged at the bottom of the spinneret box, wherein N is a natural number greater than or equal to 1. M spinneret holes are formed in the side of the spinneret module, backing to the spinneret box, wherein M is a natural number greater than or equal to 1. The electrostatic generator generates an electrostatic field at the exit of the spinneret holes. The spinning liquid is solidified and formed into the fibrous material when ejected from the spinneret holes under the effect of the electrostatic field. The elector spinning device is capable of conveniently adjusting the proportion of polymer in the woven fibers.

Description

technical field [0001] The invention relates to the field of textile equipment, in particular to an electrostatic spinning equipment. Background technique [0002] Electrospinning is a special form of electrostatic atomization of polymer fluid. Its principle is: under the action of electrostatic generator, a high-voltage electrostatic field is formed between the electrospinning liquid spraying device and the electrospinning fiber receiving device, and the polymer solution Droplets are formed at the nozzle and charged, and the charged droplets are accelerated at the top of the Taylor cone under the action of the electric field force. When the electric field force is large enough, the charged droplets overcome the surface tension to form a charged jet, and the charged jet runs in the electrospinning space When the solvent is volatilized, bent and stretched, it is finally collected by the receiving device to form randomly arranged electrospun fiber materials. [0003] Electros...
