Problems solved by technology

[0003] Due to the limitations of the electrospinning method, the polymer can only be extracted and landed on the receiving plate, so the fiber array is planar and cannot be formed in one piece. It needs to rely on multiple layers and multiple stacks to form. The forming is slow and requires time is also longer
The membrane stress of the textile is also relatively low and the thickness and pore size are uneven, and when the textile is used as a material such as a mask, the barrier rate of the textile is low

Abstract

The present invention relates to a 3D electrospinning method, comprising the following steps: S1, making polymer spinning liquid foam through a bubble generating device, the bubble generating device is a micro-nano bubble generating device; S2, applying an electrostatic field to the foam, and the electrostatic The field is used to provide an electric field force to guide the foam to flow into the operating cabin; S3, store the foam in the operating cabin, operate the operating cabin under negative pressure to rupture the foam; S4, obtain 3D electrospun fabrics. The invention changes the traditional working method of electrospinning. Firstly, foaming treatment is carried out on the textile liquid, and then the foam is guided into the cabin by static electricity, and the negative pressure operation is carried out in the cabin. The foam bursts instantaneously under negative pressure conditions, and the foam forms a 3D textile.

Description

technical field [0001] The invention relates to the field of electrostatic spinning, and specifically refers to a 3D electrostatic spinning method and equipment thereof. Background technique [0002] The traditional electrospinning method is the polymer jet electrostatic drawing spinning method. Firstly, the polymer solution or melt is charged with thousands to tens of thousands of volts of high-voltage static electricity. The Taylor cone apex is accelerated. When the electric field force is large enough, the polymer droplets overcome the surface tension to form a jet stream. The thin stream evaporates or solidifies the solvent during the spraying process, and finally falls on the receiving device, forming a fibrous mat like a nonwoven cloth. [0003] Due to the limitations of the electrospinning method, the polymer can only be extracted and landed on the receiving plate, so the fiber array is planar and cannot be formed in one piece. It needs to rely on multiple layers an...
