Description

technical field

[0001] The invention belongs to the field of filter materials and preparation thereof, in particular to a multi-layer spunmelt electret filter material containing energy-enhancing additives and a preparation method thereof. Background technique

[0002] The rapid development of modern industry has made my country's economy develop rapidly and the living standards of the people have been greatly improved, but the development of industry has brought us serious air pollution problems. The air contains a large amount of harmful gases and fine suspended particles, which cause serious harm to human respiratory tract, cardiovascular system and central nervous system, and directly threaten human health. Therefore, reducing harmful substances in the air is crucial for environmental protection and safeguarding human health. At present, the most economical and effective air filtration method is fiber filtration technology.

[0003] Due to the structure of the three-di...
