Anping County Boli Hardware Wiremesh Products Factory, established in 1998 with an annual export value of US$5-10 million, is a professional manufacturer dedicated to high-quality filtration solutions. Our PET Filter Cloth for Belt Filter is a spunbond nonwoven fabric, thermally bonded, with a weight range of 200-800 gsm and filtration efficiency of 10-50 micron. This product is engineered to deliver consistent performance in solid-liquid separation processes, offering excellent durability, chemical resistance, and precise filtration. Trusted by clients across North America, Europe, Asia, and beyond, our filter cloth is a reliable choice for demanding industrial applications.
The fabric is made from 100% polyester (PET) fibers, which provide outstanding resistance to acids, alkalis, and organic solvents, ensuring long service life even in harsh environments. The spunbond manufacturing process creates a uniform, high-strength web with excellent dimensional stability, while thermal bonding enhances the fabric's integrity and prevents fiber shedding. Our filter cloth is available in a wide range of weights (200-800 gsm) and can be customized to achieve specific filtration ratings from 10 to 50 microns, making it suitable for various belt filter designs.
Key Features & Technical Specifications
- High Filtration Efficiency: Precise pore size control from 10 to 50 microns ensures effective capture of particles while maintaining good permeability.
- Thermal Bonded Structure: The fibers are fused together without chemical binders, providing a smooth, non-shedding surface that reduces clogging and facilitates easy cake release.
- Wide Weight Range (200-800 gsm): Choose the optimal weight for your application — lighter fabrics for higher flow rates, heavier fabrics for greater mechanical strength and longer life.
- Excellent Chemical & Temperature Resistance: PET material operates reliably in temperatures up to 150°C (302°F) and withstands common acids, alkalis, and solvents.
- Uniform Fiber Distribution: Spunbond technology ensures consistent web density, leading to predictable filtration performance across the entire fabric surface.
- Customizable Dimensions: Available in various widths (up to 6 meters) and lengths per roll, tailored to fit your belt filter equipment.
- Low Maintenance: The smooth surface resists particle adhesion, reducing downtime for cleaning and extending operational intervals.

Frequently Asked Questions (FAQ)
- What is the maximum temperature this filter cloth can withstand? The PET fabric can operate continuously up to 150°C (302°F). For higher temperature applications, other materials may be recommended — please consult our team.
- Is the filter cloth resistant to acids and alkalis? Yes, polyester has good resistance to most organic acids, alkalis, and solvents. However, strong oxidizing agents or concentrated acids may degrade the material. We can provide detailed chemical compatibility data upon request.
- Can you customize the width and length? Absolutely. We can produce rolls up to 6 meters wide, and any length per roll is available. Custom widths and lengths are our specialty.
- What is the minimum order quantity (MOQ)? MOQ depends on the weight and dimensions. Typically, we accept orders starting from 100 square meters. For specific requirements, please contact us.
- Do you offer samples for testing? Yes, we provide free samples (shipping cost may apply) for evaluation. Please send your inquiry with detailed specifications.
- How does the filtration efficiency compare to needle-punched felt? Our thermally bonded spunbond fabric has a smoother surface and lower pressure drop than needle-punched felt, while offering comparable filtration precision. It is particularly effective for fine particle retention and easy cake release.
- What industries commonly use this product? It is widely used in mineral processing, chemical & pharmaceutical, food & beverage, wastewater treatment, and industrial sludge dewatering belt filters.
- Can the fabric be welded or seamed? Yes, thermal bonding allows for ultrasonic welding or heat sealing. Mechanical seaming is also possible. We can provide pre-fabricated belts or sheets per your requirements.
