In the process, the coiled material 10 is subjected to four steps of electret treatment, so that the electret treatment time is greatly prolonged, the electret treatment time of the melt-blown non-woven fabric reaches about 20S, the filtration efficiency after treatment reaches a peak value, and the uniformity of the air permeability of the melt-blown fabric is improved. If the electret time is short, the charge surface density of the melt-blown surface is not uniform, and the charge repulsion action is strong at places with higher charge density, so that a larger open structure is formed on the surface of the filter material, the pores are enlarged, and the air permeability is increased; when the electret time is prolonged, the density of the deposited charges is relatively uniform, and the repulsion action of the charges in each tiny pore is not greatly different, so that the fiber is slowly restored to a uniform state, and the air permeability is enabled to reach a uniform state.

The melt-blown electrostatic electret device can still greatly improve the filtering effect under the condition of not increasing the thickness of the coiled material 10 (namely under the condition of breathing resistance).
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
