Polyester needle felt is a filter cloth made of polyester fiber, which is made by non-woven needle punching process. The polyester staple fibers are combed and laid on the fiber cloth and then needled into felt. The dense fabric is formed by mechanical needle punching. Due to its high filtration efficiency, good wear resistance and chemical compatibility with a variety of substances, this fabric is widely used in solid-liquid separation processes in various industries.

Description
Polyester Needle Felt Filter Fabrics Offer a Number of Key Properties
- High Filtration Efficiency: Polyester has excellent particle retention, effectively capturing fine particles and dust.
- High Temperature Resistance: Polyester can withstand moderate temperatures, typically up to about 130-150°C (266-302°F).
- Mechanical Strength: It has good tensile strength and dimensional stability.
- Abrasion Resistance: The fabric is resistant to abrasion, prolonging its service life even in demanding filtration applications.
- Ease of Cleaning: Polyester needle felt can be cleaned and maintained easily, either through mechanical shaking, air pulsing, or washing.

Post-Treatment of Polyester Needle Felt
We can treat it with different post-processing according to different working conditions. There are mainly the following post-processing treatments:
- Anti-Static (line type, cross line type, blend type).
- Anti-Spark.
- Water & Oil Repellent.
- Anti-Abrasion (Acrylic coating).
- PTFE Membrane.
- PTFE Impregnation.

Advantages of Filmedia® Polyester Needle Felt
- The pores of polyester needle punched filter felt are evenly distributed, with a porosity of 70%, which is twice that of woven filter cloth. High dust removal efficiency and low gas emission concentration.
- The surface of the polyester needle-punched filter felt is hot-rolled, singed or coated, making it smooth and smooth, not easy to block or deform, easy to clean, and has a long service life.
- Anti-static needle punched felt has the function of preventing corrosion and discharging electrostatic discharge generated by blast furnace gas and cement plant coal mill.
- The capable of manufacturing 15,000 square meters per day (standard PE product). You can choose pure PE needle felt, PE blending needle felt , anti-static needle felt and water and oil proof needle felt. We also have SGS Qualifications of PE series product.
Application of Polyester Needle Felt
Some common applications include:
- Dust Collection: Used in baghouse systems to capture dust and particulate matter in industries such as cement manufacturing, asphalt production, and woodworking.
- Air Pollution Control: Deployed in air filtration systems to reduce emissions from industrial processes and power generation facilities.
- Wastewater Treatment: Employed in filter presses and other filtration equipment to separate solids from liquids in municipal and industrial wastewater treatment plants.
- Chemical Processing: Used for filtering and separating chemicals and pharmaceutical products in manufacturing processes.
- Food and Beverage: Used in filtration systems for clarifying liquids, such as wine, beer, and fruit juices, to remove impurities and improve product quality.
- Metal Processing: Applied in metalworking industries to filter coolant fluids and remove metal fines and debris from cutting and grinding operations.
- Power Generation: Utilized in power plants for filtering ash and particulates from flue gases in coal-fired boilers and other combustion processes.
- Environmental Protection: Used in environmental remediation projects to filter contaminants from soil and groundwater.
- Pharmaceutical Industry: Applied in pharmaceutical manufacturing for sterile filtration and clarification of liquids and gases.
