Non-woven filter material: Green guardian in the field of air purification

With the increasing environmental pollution, air purification has become an indispensable part of our daily life. In the field of air purification, non-woven filter materials, with their unique advantages, have become the core materials of air filters, masks and other products, building a solid line of defense for our living environment.

Non-woven fabrics, a seemingly ordinary but technological material, shine in the field of air purification with its efficient filtering performance and good air permeability. Compared with traditional textile materials, non-woven fabrics have higher fiber density and smaller pore size, which enables them to more effectively capture harmful substances such as particulate matter, bacteria, viruses and other harmful substances in the air. At the same time, the air permeability of non-woven materials also ensures the smooth flow of air during the filtration process, providing users with a fresh and odor-free air environment.

Among the many non-woven materials, polylactic acid non-woven fabrics are particularly prominent in the air filtration industry with their unique environmental protection characteristics. Polylactic acid is a bio-based, degradable material that comes from renewable resources such as corn starch and sugarcane, and has excellent biocompatibility and biodegradability. This means that when masks or air filters made of polylactic acid non-woven fabrics are discarded, they can be decomposed by microorganisms in the natural environment and eventually converted into water and carbon dioxide, which greatly reduces the pressure of discarded masks on the environment.

In addition to its environmental protection characteristics, polylactic acid non-woven fabrics also have excellent filtering performance and breathability. Its fiber structure is fine and can effectively block tiny particles in the air while maintaining the free flow of air. This makes polylactic acid non-woven fabrics an ideal material for making masks and air filters, providing users with a safe and comfortable breathing experience.

In addition, ultrafine non-woven fabrics have also been widely used in the field of mask filter materials due to their soft, breathable and wear-resistant characteristics. The fiber diameter of ultrafine non-woven fabrics is usually less than 1 micron, which makes its surface area larger and the porosity higher, so that it can more effectively capture harmful substances in the air. At the same time, ultrafine non-woven fabrics also have good softness and breathability, making masks more comfortable to wear and reducing the user's breathing resistance.

In the medical field, ultrafine non-woven masks have become essential protective equipment for medical staff and the public. They can not only effectively block bacteria and viruses in the air, but also prevent the spread of droplets, providing better protection for medical staff and patients. During the epidemic, ultra-fine non-woven masks have become an important material for fighting the epidemic and have made great contributions to epidemic prevention and control.

Non-woven filter materials play an irreplaceable role in the field of air purification with their efficient filtering performance, good air permeability and unique environmental protection characteristics. With the continuous advancement of science and technology and the improvement of environmental awareness, the application of non-woven filter materials will be more extensive, bringing more green and health to our living environment.
