Yuzhimu Filtration Support Fabric: High Air Permeability and Excellent Stiffness for Advanced Filter Manufacturing

To meet different filtration requirements, Yuzhimu offers a complete range of filtration support fabrics with basis weights from 65 g/m² to 90 g/m². The standard product lineup includes ATLBack-65B, ATLBack-70B, ATLBack-75B, ATLBack-80B, and ATLBack-90B, allowing filter manufacturers to select the most appropriate support layer according to airflow resistance, media structure, and product performance targets.

One of the key advantages of this series is its outstanding air permeability. The 65 g/m² fabric delivers approximately 5,400 L/m²/s (ISO 9237), providing exceptionally low airflow resistance for high-efficiency filtration systems. The 70 g/m² grade maintains 5,200 L/m²/s, while the 75 g/m² specification offers 5,000 L/m²/s. As basis weight increases, airflow remains consistently high, with the 80 g/m² fabric achieving 4,700 L/m²/s and the 90 g/m² version maintaining 4,500 L/m²/s. This carefully balanced performance enables excellent ventilation while providing sufficient mechanical support for multilayer filter constructions.

In addition to high airflow, the support fabric exhibits progressively increasing stiffness, making it highly suitable for pleating and automated filter production. The 65 g/m² grade has a stiffness value of 80 mg according to ASTM D6125, increasing to 90 mg for the 70 g/m² product, 100 mg for 75 g/m², 110 mg for 80 g/m², and reaching 120 mg for the 90 g/m² specification. The gradual increase in stiffness helps maintain pleat geometry, improves dimensional stability, and enhances manufacturing efficiency during high-speed production.

Yuzhimu also provides customized solutions to satisfy diverse market demands. The ATLBack-65Y model offers the same excellent airflow of 5,400 L/m²/s and 80 mg stiffness while being available in yellow or other custom colors, making it suitable for products requiring visual differentiation or brand-specific identification. For applications where hygiene is critical, the ATLBack-70BV antibacterial series combines 70 g/m², 5,200 L/m²/s air permeability, and 90 mg stiffness with antibacterial functionality to help reduce microbial growth on the support layer. For even more demanding environments, the ATLBack-70BVM version incorporates both antibacterial and anti-mould properties, providing additional protection for filtration systems operating in humid or challenging conditions.

The combination of high air permeability, optimized stiffness, lightweight construction, and functional customization makes Yuzhimu filtration support fabric an excellent choice for a wide range of filtration products. Whether used in activated carbon composite filters, cabin air filters, industrial ventilation systems, HVAC filtration, or multilayer filtration media, the fabric delivers reliable support while helping manufacturers achieve consistent product quality and production efficiency.

With basis weights ranging from 65–90 g/m², air permeability from 4,500 to 5,400 L/m²/s, stiffness values between 80 and 120 mg, and optional custom colors, antibacterial, and anti-mould treatments, Yuzhimu filtration support fabric provides a versatile and dependable solution for today's advanced filtration industry. Its balanced mechanical performance and excellent airflow characteristics make it an ideal support material for manufacturers seeking both high productivity and superior filtration performance.
