Product Description
Polyester Staple Fiber is a versatile synthetic fiber used in filtration materials and other industrial textile applications where stable performance, good processability and cost-effective production are important.
Our polyester fiber products are supported by long-term experience in specialty fiber processing and filtration manufacturing. Rather than focusing only on the fiber itself, we work across the production chain from fiber materials to needle-punched filtration media and finished filter bags.
What Makes Polyester Fiber Suitable for Filtration?
Good Air Permeability
Proper airflow is essential for an efficient dust collection system. The supplied polyester needle-felt specification indicates an air permeability range of approximately 80–130 m³/m²·min, depending on the product specification.
01
Flexible and Wear Resistant
Industrial filter media experience repeated mechanical movement during operation and cleaning. Polyester needle-punched felt is described as having good flexibility and wear resistance, helping it withstand these working conditions.
02
Smooth Surface for Dust Cleaning
After finishing, polyester filter felt has a relatively smooth surface that supports effective removal of accumulated dust during filter cleaning.
03
Suitable for Normal-Temperature Systems
The supplied technical data gives polyester needle-punched felt a continuous and instantaneous operating temperature of around 150°C. Actual selection should always be based on the complete filter construction and the customer's operating conditions.
