Types and Characteristics of Industrial Filter Fabrics: There are many types of industrial filter fabrics, and generally, 12 different kinds are commonly available on the market. So, what exactly are these 12 types of filter fabrics, and what functions do they each serve? Let’s take a detailed look at this topic together.
1. Polyester industrial filter cloth
It features high strength, excellent wear resistance, low elongation, good acid resistance, and is soluble in high-temperature, strong alkaline solutions. Under certain conditions, it may undergo hydrolysis and become brittle. It exhibits good resistance to dry heat up to 150°C and maintains its shape well. Its primary applications include dust collection from high-temperature gases in cement, ironmaking, and iron-carbon plants; filtration of refined white earth in oil refineries; and filtration in oil and fat processing plants, wineries, and chemical plants.
2. Polypropylene industrial filter cloth
Lightweight and easy to handle, it exhibits excellent resistance to both acids and alkalis but is prone to aging. It is primarily used for the purification of dyes and pigments, as well as for filtering clays, ceramic soils, chemical substances, and various industrial applications such as sugar refining, beer production, refined oil processing, and the treatment of industrial wastewater and municipal sewage systems.
3. Vylon Industrial Filter Cloth
It exhibits good alkali resistance but relatively poor temperature resistance, and shrinks when wet—especially when heated. The primary applications of industrial filter cloths include filtration in the dye, pigment, ceramic clay, and pharmaceutical industries.
4. Acrylic industrial filter cloth
It exhibits excellent chemical resistance and is primarily used for dust collection from corrosive gases, among other applications.
5. Nylon industrial filter cloth
It features high strength, excellent wear resistance, a smooth surface, outstanding slag-release performance, and good alkali resistance. However, it is susceptible to erosion by inorganic acids, exhibits significant elongation, and is prone to deformation. It is primarily used in mineral processing, wax melting in refineries, filtration in chemical plants, treatment of industrial wastewater and municipal sewage, and the production of sodium silicate.
6. Cotton industrial filter cloth
It primarily leverages the swelling property of cotton fibers and is well-suited for capturing fine particulate matter. Its main applications include general liquid filtration and dust collection. What are the types and characteristics of industrial filter fabrics?
7. Vinyl chloride industrial filter cloth
It exhibits excellent wear resistance, resilience, antistatic properties, and flame retardancy. It is primarily used for manufacturing flame-retardant filter fabrics.
8. Polyvinylidene chloride industrial filter cloth
It features high wear resistance, mold resistance, and decay resistance; it does not absorb moisture and does not expand when immersed in water. It is primarily used for filtering corrosive liquids and gases.
9. Glass fiber industrial filter cloth
It exhibits high tensile strength, low elongation, high temperature resistance, excellent thermal stability, good electrical insulation, and strong resistance to chemical corrosion. However, its torsional strength and shear strength are relatively lower compared to other fibers. Its primary applications include dust collection from high-temperature gases and the recovery of valuable industrial products.
10. Aramid industrial filter cloth
High strength and excellent heat resistance—can be continuously used at temperatures ranging from 180 to 200 degrees Celsius. It exhibits outstanding chemical resistance, is mold-resistant, has good radiation resistance, and is flame-retardant. Primarily used as filter bags for filtering gases and separating solid particles under high-temperature conditions, such as in stone powder plants, highly explosive aluminum powder plants, and other industrial filtration applications.
11. Carbon fiber industrial filter cloth
It has a high elastic modulus, low density, high tensile strength, excellent heat resistance, good resistance to chemical corrosion, excellent dimensional stability, and outstanding electrical conductivity. Its main applications include chemical filtration at high temperatures and activated carbon fiber felts used for air purification.
12. Fluorine-containing fiber industrial filter cloth
It exhibits excellent chemical corrosion resistance, good thermal stability, low electrical and thermal conductivity, superior electrical insulation, and excellent flame retardancy. Its coefficient of friction is among the lowest of synthetic fibers. It is primarily used for filtration in high-temperature and chemically aggressive environments, such as the fluoropolymer felt filter media employed in titanium dioxide plants.
