Fibrous filtration materials play a significant role in the filtration domain due to their simple structure, uniform porosity, exceptional filtration performance, high throughput, and cost-effectiveness. By combining different types of fibers, a synergistic blend of strengths and efficiency can be achieved, resulting in robust and highly effective filtration materials. Various manufacturing processes, such as different weave patterns in textiles, the knitting methods in knits, and the reinforcement techniques in nonwovens, can produce filtration materials adaptable to a variety of environments.

Woven filtration materials are formed through the intertwining of warp and weft yarns. While they offer convenient cleaning, high strength, and long lifespan, their relatively large straight-through pores make achieving high-precision filtration challenging, resulting in relatively high filtration resistance. Knitted filtration materials, on the other hand, can block smaller particles due to internal channel bending but are prone to structural changes and yarn breakage, affecting their lifespan and filtration stability.

Nonwoven filtration materials are widely popular for their simple production processes, high speed, high yield, and low cost. Compared to traditional woven filtration materials, nonwoven materials feature a unique three-dimensional mesh structure with a large internal surface area and high porosity, making them the most commonly used filtration materials currently available.

Composite filtration materials combine the advantages of multiple materials to provide efficient filtration performance. For example, SMS composite materials combine the excellent filtration performance of meltblown materials with the high strength of spunbond fabrics, while film materials like PTFE film offer uniform pore sizes and high temperature resistance, acid and alkali resistance, and prolonged lifespan.

Fiber raw materials are diverse, including glass fibers, polyimide fibers, quartz fibers, ceramic fibers, and more. These fibers and their composite materials are particularly suitable for high-temperature and corrosion-resistant filtration applications, and have been widely applied in various industries such as power, chemical, and steel, bringing significant economic and environmental benefits.
