Electrostatic cotton is a high-performance filter material. Made from short PP fibers, it undergoes carding and needle punching to form a web, followed by electrostatic electret treatment, giving it a powerful electrostatic adsorption capacity. Compared to ordinary filter materials, electrostatic cotton has a higher filtration efficiency, effectively adsorbing fine particles in the air, such as dust, pollen, and bacteria. Its filtration efficiency for 0.3μm NaCl aerosol particles can reach 60%-99%. Simultaneously, it has good resistance and dust holding capacity, allowing for stable operation over extended periods and reducing the frequency of cleaning and replacement. Electrostatic cotton is widely used in air purification, industrial dust removal, and other fields, playing a vital role in creating a clean air environment .
