Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
The present invention provides a kind of electrospinning process of three free surface water-spraying fabrics to include the following steps：
Three free surface spray heads are placed according to position as shown in Figure 1, 2, 3 to the lower section of reception device respectively, are sprayed
Crown end free surface is apart from reception device 200mm.Free surface spray head uses diameter for the umbrella shower nozzle of 25mm, spray head spacing
It is set as 30-70mm, the reception device base fabric speed of service is set as 2m/min.
Three free surface spray head independent loads voltages apply voltage and free surface be inspired more completely to penetrate
Stream, attenuating drawing-down are received at nanofiber by base fabric.
According to the yield of four free surface spray heads in the nanometer fiber net areal calculation unit time being collected into base fabric.
The critical electricity of the free surface electrostatic spinning nozzle in embodiment is calculated below by way of electric field simulation software ansys
Pressure value.
When three spray head spinning, within the scope of certain distance, since its mutual electrostatic field makes electric field by dry
It disturbs.And there are certain interactive relations for the diameter of spray head spacing and spray head.In the present embodiment, analog parameter is as follows：Free liquid
Face spray head be it is cylindric, bottom cylindrical face diameter is 25mm, the high 50mm of cylindrical body, and the spacing between adjacent spray head is 30-70mm, material
Material is brass.Emulation voltage is 50kV, and region calculated is the cube that a side length is 200mm.
With the increase of head spacing, electric jamming weakens, and the weakening that spray head top field strength is subject to reduces, three kinds of arrangement modes
Critical voltage needed for spinning reduces with the increase of head spacing.After head spacing increases to 55mm, electric jamming is very
Weak, critical voltage drives in stabilization.Critical voltage needed for three kinds of arrangement modes is from big to small：Linear arrangement > isosceles right angle trigonometry
Shape arrangement > equilateral triangle arrangement.
