Dust collector filter bags are carefully manufactured to achieve optimal filtration. These bags are made from virgin needle felt fabric, and are highly efficient to reduce dust emission levels.
The filter bags are placed inside dust collector systems with supporting filter cages. When the polluted or contaminated air comes in contact with these filter bags, the solid particles get deposited on the outer surface, and clean air passes through. The particles deposited on the outer surface get collected at the bottom when pulsing takes place.
Non-woven bags can be made using polyester, polyphenylene sulfide, meta aramid, homopolymer, and even polypropylene.

- Polyester
Polyester is one of the most durable and strong fabrics available, and it is created from 100% virgin polyester filaments. This fabric finds use in a wide range of applications like medical facilities, construction, cement plants, power plants, and aluminum plants , to name a few.
Polyester is good for applications with temperatures ranging from 140-150 degree Celsius, and a variety of treatment options are available to give the fabric additional characteristics.
Some of these treatments are:
- Antistatic treatment
- Oil and water repellent coating
- Flame retardant
- PTFE finish
- Homopolymer
Homopolymer finds application in ceramic plants and aluminum plants, especially when there is moisture. Homopolymer is a good alternative to polyester when there is a problem regarding hydrolysis. There are blends of acrylic and polyester available as well. Homopolymer is good for temperatures within 125 degree Celsius. A variety of treatment options available to give the fabric additional characteristics.
Some of these treatments are:
- Antistatic treatment
- Oil and water repellent coating
- Flame retardant
- PTFE finish
- Meta-aramid
Meta-aramid is a flame resistant and high temperature fabric and resists ignition. The fabric is resistant to a wide range of chemicals and finds use in many modern industrial applications. Meta aramid is good in high temperatures, as it can sustain up to 200-220 degree Celsius. The fabric has excellent chemical resistance to organic solvents and hydrocarbons, and has high tensile strength. However, meta aramid has a reduced life if sulfur dioxide or sulfur trioxide is present.
A variety of treatment options available to give the fabric additional characteristics.
Some of these treatments are:
- Antistatic treatment
- Oil and water repellent coating
- Flame retardant
- PTFE finish
- Polyphenylene Sulfide
Polyphenylene sulfide is commonly known as Ryton or PPS, and is a fabric that is highly resistant to acids, alkalines, and organic solvents. The fabric is flame and hydrolysis resistant as well, and apt for industries where environmental conditions vary. The fabric has high tensile strength and has good mechanical stability. PPS can sustain temperatures up to 190-200 degree Celsius.
A variety of treatment options available to give the fabric additional characteristics.
Some of these treatments are:
- Antistatic treatment
- Oil and water repellent coating
- Flame retardant
- PTFE finish
