Description

technical field [0001] The invention belongs to the technical field of melt-blown materials, in particular to a high-efficiency and low-resistance melt-blown material and a preparation process thereof. Background technique [0002] With the aggravation of air pollution and the increase of respiratory infectious diseases, people are facing a severe air environment and hidden dangers of respiratory infectious diseases. From the perspective of national development planning, how to control the existing atmospheric environment and how to reduce air pollution in terms of personal health The hazards of pollutants and respiratory infectious viruses have become the focus of attention in today's society. People have paid more and more attention to their own respiratory health, and more and more masks and air purifiers have set off a wave of consumption in the market. [0003] Whether it is an air purifier for household appliances or a mask for personal protection products, it uses me...
