The filtration principle of nonwoven fabrics

Yuzhimu non-woven fabric is one of the core materials of air filters, with excellent filtration performance. Through special structural design, our non-woven fabric can capture small particles in the air, such as dust, bacteria, pollen, and smoke.In people's daily lives, there are many sources of indoor pollution, such as smoke, odors, bacteria, etc. Non woven fabrics, as an important component of filters, can effectively intercept these harmful substances and provide fresh and healthy indoor air. Using Yuzhimu non-woven fabric can filter out harmful substances and reduce the impact of indoor air pollution on physical health.

一、The filtration principle of non-woven fabrics：

1. Interception effect: The fibers in non-woven fabrics are tightly arranged and have a short distance between them, which can effectively intercept various particles and liquids, such as dust, smoke, microorganisms, bacteria, etc. in the air.

2. Adhesion: The fiber surface structure of non-woven fabrics is complex, with certain adsorption and ion exchange properties, which can adsorb harmful substances such as pollutants and odors, thereby improving filtration efficiency.

3. Stretching effect: Non woven fabric materials have certain stretching properties, which can deform appropriately during the filtration process, increase mesh size and porosity, and thus improve filtration efficiency.

二、 Application of non-woven fabrics in the field of filtration：

1. Air filter: People's requirements for indoor air quality are increasing. The use of non-woven fabrics in air filters can effectively remove odors, fine dust, and harmful substances in the air, such as PM2.5 and respiratory viruses.

2. Liquid filters: Non woven fabrics can be made into various liquid filters, such as water treatment filters, automotive liquid filters cartridges, etc., which can remove impurities and harmful substances from them.

3. Food filter: Non woven fabrics are widely used in food processing, which can not only filter activated carbon and powder, but also effectively kill and filter microorganisms in food.In short, non-woven fabrics, as a material with excellent filtration functions, are widely used in filters in various fields.
