Definitions
- the present invention relates to the technical field of non-woven fabrics, in particular to an antibacterial non-woven fabric, a preparation method thereof, and a mask with the antibacterial non-woven fabric.
- air pollutants are mainly divided into harmful gases and particulate matter.
- air pollutants there are more than 100 kinds of air pollutants known.
- Haze is an aerosol system formed by water vapor and particulate matter in the atmosphere.
- Atmospheric particulate matter refers to a multiphase system mixture composed of solid or liquid particles suspended in the air.
- the sources of atmospheric particulate matter are mainly divided into natural pathways and human activities; sand and dust storms in nature are the main source of atmospheric coarse particles, and natural actions such as volcanic eruptions also emit a certain amount of atmospheric particulate matter.
- the anthropogenic sources of particulate matter mainly refer to various combustions. Reactions, transportation and industrial processes, etc. There are obvious differences in the damage caused by fine particles of different sources, properties, and composition to the body. According to a study in the United States, for every increase in the concentration of fine particles from automobile exhaust by 10 ⁇ g/m3, the total mortality rate increases by 3.4%; There is no correlation between fine particulate matter, whose main source is ground dust, and total mortality.
- the physical, chemical and optical properties of atmospheric particulate matter are closely related to the particle size, and the particle size of the atmospheric particulate matter can determine the atmospheric life of the particulate matter and the location and toxicity of the final entry into the human body.
- the particle size of atmospheric particles generally adopts the effective diameter notation, that is, the aerodynamic diameter.
- the total suspended particles with a particle size of 10-100 ⁇ m cannot be breathed into the nasal cavity.
- the coarse particles with a particle size of 2.5-10 ⁇ m mostly stay in the nose and pharynx.
- the fine particles with a particle size of less than 2.5 ⁇ m are often heard.
- PM2.5 and PM2.5 can reach the alveoli deeply.
- the particle size of fine particles is small and the surface area is relatively large.
- the surface adsorbs a large amount of organic pollutants, acid oxides, nano-quartz and other minerals, toxic heavy metals, bacteria and germs, etc. It enters the human body through the respiratory tract, especially the ultrafine particles of about 0.1 ⁇ m are deposited in the lungs, and can even penetrate the alveoli and enter the blood circulation, which is the most harmful to human health.
- the dust blocking efficiency of a mask is based on its blocking efficiency for fine dust, especially for respirable dust below 5 microns. Because dust of this particle size can directly enter the alveoli, it has the greatest impact on human health.
- General gauze masks the principle of dust blocking is mechanical filtration, that is, when dust hits the gauze, it passes through layers of barriers, blocking some large particles of dust in the sand cloth. However, some fine dust, especially dust less than 5 microns, will pass through the mesh of the gauze and enter the respiratory system.
