Product Description
Polyester Needle Felt is a widely used filtration material manufactured by needle punching polyester fibers onto a supporting fabric. It is designed for normal-temperature dust collection and can be used in a broad range of industrial filtration systems.
The supplied technical document describes polyester needle felt as a commonly used normal-temperature filtration material with good wear resistance, flex resistance, air permeability, and easy dust release after finishing treatment.
Key Features
Good Air Permeability
A filter needs to capture dust without unnecessarily restricting airflow.
The polyester needle-punched structure provides good air permeability, making it suitable for dust collectors that need a balance between filtration and airflow.
01
Resistant to Wear and Repeated Flexing
Filter bags are repeatedly exposed to airflow, dust loading, and cleaning cycles. Polyester filtration felt offers good resistance to wear and flexing, making it suitable for demanding day-to-day industrial use.
02
Smooth Surface for Easier Cleaning
The supplied material notes that normal-temperature needle felt can receive finishing treatments that create a smooth surface and improve dust-cleaning performance.
For a bag-house operator, this matters because easier dust release can help maintain effective filtration during cleaning.
03
Suitable for High-Dust Industrial Environments
Polyester needle felt is intended for normal-temperature dust filtration and is widely used as a filter bag material in industrial dust collectors.

FAQ
Q: What are the main advantages of polyester filter felt?
A: Its main advantages include good air permeability, wear resistance, flex resistance, and a stable nonwoven structure. Proper finishing can also improve surface smoothness and dust-release performance.
Q: What temperature can polyester needle felt withstand?
A: The supplied technical table lists polyester needle felt with a temperature resistance of approximately 150°C. Actual operating limits should be confirmed according to the specific product grade and working conditions.
Q: Can the felt surface be specially treated?
A: Yes. The supplied product range includes easy-cleaning, PTFE membrane, anti-static, and oil/water-repellent needle-punched filtration materials.
