The filter cloth for bag house filters is a key component of the bag house filter. This kind of filter cloth is usually made of high-strength fiber materials, such as polyester fiber, polypropylene fiber or glass fiber. They feature a microporous structure that effectively traps dust particles in the air while maintaining good breathability.
- Material: Fiberglass, polyester, polypropylene, Nylon, etc.
- Application: Mining and metals, Waste processing, Chemicals, Bio-processing, Food industries, Pharmaceuticals, Petroleum and petrochemicals.
Description
Filmedia®’s woven filter cloths are adapted to the different needs of the customers, like plate dimension, cake weight, particle retention or productivity. As a result, Filmedia® has developed a wide range of standard and specific designs, making up options for fixations, barrel and rubber neck, or sealing.
Yarn Types
- Mono-filament synthetic 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 synthetic fiber fabric
A multifilament fiber consists of several fine monofilament fibers spun together. It has good properties of High filtration precision.
- Monofilament-Multifilament fiber fabric(Mono-Mult)
Mono-Mult fiber filter fabric is mixed weave by monofilament and multifilament. Mono-Mult fiber filter fabric is designed to filter very fine and sticky particles. This fabric combines the advantage of monofilament and multifilament filter fabric.
- 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.
Comparison of Various Yarn Types
| Characteristic | Very good | Good | Poor |
| Filter precision | Staple | Multifil | Monofil |
| Flow rate | Monofil | Multifl | Staple |
| Minimum moisture in cake | Monofil | Multifil | Staple |
| Easier cake release | Monofil | Multifil | Staple |
| Maximum fabric working life | Monofil | Multifil | Staple |
| Least tendency to blind | Monofil | Multifil | Staple |
