Woven Filter Fabrics
Woven filter fabrics are one of the most important categories of industrial filtration media. Manufactured by weaving synthetic or natural fibers into precise fabric structures, they play a critical role in both solid-liquid separation and air filtration processes. Thanks to their excellent mechanical strength, dimensional stability, and customizable filtration performance, woven filter fabrics are widely used across numerous industrial filtration applications.

Fiber Structure Types
Different yarn structures have different filtration characteristics, and the appropriate filter material can be selected according to the specific working conditions.
Mono-filament Fiber Fabric
Monofilament yarns are single extruded synthetic filaments, produced in diameters from approx. 28 microns up to 2 or 3 mm. It has good properties of High flow rate, high filtration efficiency, Very smooth surface, free of clogging, easy cake release, Low cleaning rate, long lifetime, The absence of the danger of small pieces of filament separating from the multifilament or staple fibers and passing downstream and resulting in contamination of the product.
Multi-filament Fiber Fabric
A multifilament fiber consists of several fine monofilament fibers spun together. It has good properties of High filtration precision. Compact yarn structure with superior tensile strength and high filtration precision. It effectively intercepts microscopic particles and is highly suited for deep filtration scenarios requiring exceptional mechanical durability.
Staple Fiber Fabric
Staple fiber yarns consist of individual cut pieces of fibers that are spun into a continuous yarn. It has the advantages of Staple fiber specific surface area is large. Staple fiber interception ability is better than monofilament, multifilament, and mono-mult.
Weave Types
The weave pattern directly influences filtration efficiency, permeability, strength, and cake release performance.
Plain Weave
- Tight structure with high filtration accuracy
Twill Weave
- Balanced permeability and anti-clogging performance
Satin Weave
- Smooth surface for improved cake release
