Paper Making Machine Polyester Woven Round Dryer Fabric for Paper Mills

Air permeability needs to be determined comprehensively based on paper type, drying speed, airflow in the drying section, and heat source. Common range: Cultural paper/thin paper is approximately 100-400 CFM; high-grammage packaging paper/paperboard can reach 700-1000 CFM or higher. We work closely with suppliers to provide detailed process parameters and make accurate selections.

There are many reason may cause this result:Improper installation: Non-parallel guide rollers, surface defects (burrs, corrosion) in the drying cylinder or rollers. Improper operation: Tension set too high or too low, severe wire misalignment, creases causing friction with the frame. Joint failure: Poor joint processing quality or improper installation.

Performance Degradation: Drying capacity remains consistently insufficient, even with optimized steam and ventilation; air permeability remains far below design values after cleaning. Physical Damage: Irreversible tears, delamination, severe wear, or permanent wrinkles occur. Chemical/Thermal Damage: The material severely hardens, becomes brittle, or suffers significant strength loss due to hydrolysis.

The minimum order quantity is 100 meters.
