Polyester felt is a non-woven felt fabric mainly made from short polyester (PET) fibers. It is produced through opening, blending, carding, web laying, needle-punch reinforcement, heat setting, and finishing processes. With a uniform pore structure and good air permeability, it delivers excellent dust-release performance. It is resistant to weak acids and weak alkalis, and offers wear resistance and tensile strength at room temperature, with strong value for money.

Features
1. Good air permeability with uniform pores for easy dust release and anti-clogging.
2. Resistant to weak acids & alkalis, wear-resistant, with high tensile strength and toughness.
3. High cost-effectiveness—economical and widely applicable.
4. Available for finishing: water-oil repellency, anti-static treatment, lamination, singeing, and hot rolling.
5. Stable dimensions, less deformation, long service life.
6. Widely used in dust removal, filtration, sealing, gaskets, polishing, geotextiles, and other applications.
1. Industrial dust removal: filter bags for cement plants, mines, woodworking, flour mills, foundries, feed mills, normal-temperature boilers, plastic processing, and more.
2. Air filtration: factory ventilation purification, dust recovery, and air-conditioner filtration.
3. Liquid filtration: chemical industry, water treatment, oil-water separation, and oil filtration.
4. Mechanical sealing & gaskets: shock-absorbing pads, dust-proof pads, wear-resistant gaskets, and cushioning materials.
5. Polishing & grinding: polishing felt wheels and polishing discs for metal and stone.
6. Geotechnical engineering: highway subgrade, water conservancy anti-seepage, isolation protection, and slope protection.
7. Packaging protection: shock-proof pads for hardware, glass, and furniture.
8. Others: DIY crafts, toy filling, inner lining of storage bags, automotive interiors, sound insulation and thermal insulation, and civil dust-proof materials.
