Firstly, in the drying and setting process of the traditional polyester spray cotton, dozens of metal rollers are closely contacted with rubber for continuous friction, and the fabric has low moisture content at high temperature, poor conductivity and difficult leakage of charges, thereby causing the continuous accumulation of static charges. When the electrostatic voltage at the operation part is too high, the operator often receives a strong electric shock. In addition, the repulsion and attraction caused by static electricity can cause folding difficulty of the fabric, and influence the processing process and the product quality. At present, in the processing process of collodion cotton carding, a spraying mode is generally adopted for lubrication, so that static electricity and dust generated by friction are avoided. However, this operation mode is not only inefficient and has an insignificant effect of eliminating static electricity, but also the equipment is corroded by water, which affects the service life.

As shown in figure 1, the extrusion device 1 is connected with the liquid storage room 2, the liquid outlet device 14 is connected with the liquid storage room 2, and the liquid outlet device 14 is connected with the electrode 3. The electrode 3, the electrode slide rail 4, the conductive metal net 5 and the metal net slide rail 6 are located in the insulating box body, the electrode 3 is connected to the electrode slide rail 4, the conductive metal net 5 is connected to the metal net slide rail 6, and flocculus is laid on one surface of the conductive metal net 5, which is located on the same side as the electrode 3. The air inlet 7 is positioned on the insulating box body, the air inlet 7 is positioned at the same side of the electrode 3, the air suction opening 8 is positioned in the insulating box body space at one side of the conductive metal net 5, which is not contacted with the flocculus, and the air suction opening 8, the insulating box body and the air suction equipment 10 are sequentially connected through a pipeline. The air inlet 7 may also be provided with a heating device, which forms a heated air circulation with the air extraction device 10. The air suction opening 8, the insulation box body, the air suction device 10 and the air inlet 7 can be connected in sequence through pipelines to form a cycle. In this embodiment, the apparatus may further comprise an air outlet 12 and an air valve 11, wherein the air outlet 12 is located between the air inlet 7 and the connecting pipe of the air draft apparatus 10 and is communicated with the external environment; the air valve 11 is positioned in a pipeline which is communicated with the air inlet 7, the air extraction equipment 10 and the air outlet 12. The high voltage generator 9 is provided with a high voltage generator output 13, the high voltage generator output 13 being connected to the electrode 3.

The adhesive is stored in the liquid storage room 2, extruded out of the liquid storage room 2 through the extruding device 1 at a certain speed, and conveyed to the electrode 3 through the liquid outlet device 14 to be sprayed out. The electrode 3 is connected to the output 13 of the high voltage generator via a wire to charge the ejected droplets, which are dispersed into fine droplets due to charge repulsion. The liquid drops are moved in the direction of the conductive metal net 5 by the blowing air, and part of the solution is allowed to volatilize. The fine liquid drops transfer charges to the flocculus, and the fibers of the flocculus are mutually repelled by the charge repulsion action and become fluffy. Alternatively, a mode of alternately blowing and sucking through hot air circulation can be adopted, and the air speed can be intermittently controlled and coordinated with the infusion unit, so that the cotton cannot be excessively dried and hardened due to the action of wind power. The main purpose of the air suction is to help the liquid drops penetrate into the inner layer of the flocculus, to be primarily dried and to have a certain guiding effect on the fine liquid drops. The electrode slide rail 4 is used for moving the electrode 3, the metal mesh slide rail 6 is used for moving the conductive metal mesh 5, and the adhesive is uniformly spread on the wadding sheet in an auxiliary manner through mechanical and electrical control. The conductive metal net 5 is grounded or connected with a micro-voltage, and the high-voltage generator 9 can be grounded. When the air inlet 7 is circulated with the air extraction equipment 10, the air extraction opening 8 and the insulation box body through pipelines, the air valve 11 controls the pressure of the system, the air extraction equipment 10 controls the wind direction and the wind speed in the system, and the air outlet 12 ensures the exchange of air with the outside in the system. The air inlet 7 is provided with a resistance wire, a bathroom heater bulb and other heating devices for controlling the temperature inside the insulating box body and the surface temperature of the flocculus. Two or more pipelines can be arranged, and cold air and hot air alternately circulate to meet different process requirements. The size and the shape of the insulating box body can be adjusted, the internal environment temperature of the equipment is maintained, stable airflow is formed during air draft, charged liquid drops are prevented from being attracted by other grounded parts, and the influence of the external environment of the equipment is reduced. The air pressure and time of negative pressure air draft depend on temperature, flake thickness and adhesive viscosity.

The voltage connected to the electrode 3 and the conductive metal mesh 5 needs to form a large voltage difference, so that the adhesive droplets move along the direction of the voltage difference. The electrode 3 can be connected with a high voltage of-15 kV to 15kV, and the connected voltage needs to be adjusted comprehensively according to factors such as the viscosity of the selected adhesive, the liquid outlet speed, the system temperature and the like. The electrode 3 is connected with the negative high voltage and the positive high voltage with the same value, the dispersion effect of the liquid drops is similar, only the liquid spraying forms are different, and if the negative high voltage is applied, the fine liquid drops are not easy to scatter to the outside of the metal net communicated with the micro positive voltage.

The conductive metal mesh 5 can be grounded or connected with a micro-voltage, and the connected micro-voltage is-70V to 70V. If the conductivity of the processed flocculus is smaller, such as pure terylene, the conductive metal net 5 can be connected with a micro negative voltage or grounded; and like natural fibers such as pure cotton, the conductivity is larger, and in order to achieve the same fluffy effect, the conductive metal net 5 can be connected with a slight positive voltage.

The mass ratio of the raw material of the flocculus mainly considers the conductivity of the raw material fiber under the conditions of wetting and drying of the adhesive so as to realize the dynamic balance of charge transmission. The raw material fiber is flexible to select and can be mixed according to the required proportion to achieve the proper conductivity. The electric conductivity of the absorbent cotton and the modified cotton is less than that of natural raw cotton because the coated cotton grease is removed, the expected electric conductivity can be achieved by blending the natural raw cotton and the terylene, and the lower the electric conductivity is, the less electric charges are transferred by the liquid drops for achieving the dynamic charge balance and the fluffy effect.
