Description
Non-woven Fabric
Non-woven fabric is a kind of fabric that connects fibers together by other methods instead of weaving or knitting. It uses physical, chemical or thermal treatment to bond fibers together to form a fiber mesh structure. Non-woven fabric does not have a regular interwoven structure like traditional fabrics. It is formed by random or regular arrangement of fibers.
The excellent filtration efficiency, high durability and adaptability to various environmental conditions of non-woven filter bags make them an excellent choice for industries that require efficient dust removal and pollution control systems. Whether used in high temperature environments or chemical heavy applications, non-woven filter bags combine performance and cost-effectiveness that are difficult to match with other filtration technologies.

Common Applications
1. Dust Collection
- Cement industry: For capturing dust generated in kilns, mills, and cement packing.
- Steel industry: In blast furnaces, sintering plants, and electric arc furnaces (EAF).
- Mining and metallurgy: To filter fine dust produced during mineral processing, crushing, and grinding.
2. Air Pollution Control
Used in systems that help industries comply with environmental regulations by controlling emissions of particulate matter. Non-woven filter bags are ideal for handling fine particulate matter and controlling air pollution.
3. Food and Pharmaceutical Processing
In these sectors, non-woven filter bags are used for filtering powders, granules, and other materials to ensure product purity and safety.
4. Powder Coating and Paints
Non-woven filter bags are used in powder coating operations to capture fine particles and prevent contamination of the product.
5. Chemical and Waste Treatment
Non-woven filter bags are also used for filtering various chemicals, sludge, and wastewater in treatment plants, offering high filtration efficiency and chemical resistance.
