Metal fiber fleece

Metal Fiber Fleece is an innovative material made from fine metal fibers processed into a nonwoven fabric. This material offers a unique combination of high strength, flexibility, and excellent filtration properties, making it extremely useful for a variety of industrial applications.

Properties of Metal Fiber Fleece

  • High Strength: Metal fiber fleece is extremely robust and resistant to mechanical stress, making it ideal for demanding applications.
  • Flexibility: Despite its strength, metal fiber fleece remains flexible and can be easily shaped into various forms without losing its structural integrity.
  • Excellent Filtration: The fine metal fibers provide high filtration performance, allowing even the smallest particles to be effectively filtered. This makes it particularly useful in air and liquid filtration.
  • Heat Resistance: Metal fiber fleece can withstand high temperatures, making it suitable for applications in high-temperature environments.
  • Corrosion Resistance: Depending on the metal used, metal fiber fleece can exhibit high resistance to corrosion, extending its lifespan in aggressive environments.

Applications of Metal Fiber Fleece

  • Air and Liquid Filtration: Metal fiber fleece is often used in filtration systems to remove contaminants from air and liquids. It is used in the automotive industry, HVAC systems, and industrial filtration systems.
  • Catalysts: In the chemical industry, metal fiber fleece is used as a carrier material for catalysts to accelerate chemical reactions and improve process efficiency.
  • Sound Dampening: Due to its damping properties, metal fiber fleece is also used in sound dampening to reduce noise in industrial and commercial applications.
  • Heat Shields: In high-temperature applications, such as aerospace or the automotive industry, metal fiber fleece is used as a heat shield to protect sensitive components from extreme heat.
  • Separation Media: Metal fiber fleece is also used as a separation medium in the oil and gas industry to separate solids from liquids and ensure the purity of end products.

Processing of Metal Fiber Fleece

The processing of metal fiber fleece requires special techniques and technologies to maintain and optimize the unique properties of the material:

  • Fiber Production: The metal fibers are produced through various processes such as drawing, cutting, or atomizing. These processes create fine fibers that are then processed into a nonwoven fabric.
  • Consolidation of the Fleece: The loose fleece is consolidated through mechanical, thermal, or chemical processes. Mechanical consolidation can be achieved through needling or water jetting, while thermal consolidation is achieved by heating and melting the fibers. Chemical consolidation involves the application of binders.
  • Cutting and Shaping: The consolidated fleece can be cut into various shapes and sizes to meet the specific requirements of the application. This can be done through stamping, cutting, or laser cutting.
  • Coating and Finishing: Metal fiber fleece can be coated or finished with various treatments to further enhance its properties. This can include the application of protective coatings, hydrophobic or oleophobic coatings, or impregnation with special chemicals.

Filtration Fineness of Metal Fiber Fleece

The filtration fineness of metal fiber fleece is a crucial factor for its effectiveness in filtration applications. It refers to the size of the particles that the fleece can retain and is often measured in micrometers (µm). Here are some important aspects of filtration fineness:

  • Particle Size: Metal fiber fleece can be designed to effectively filter particles within a specific size range. This can range from coarse particles (several hundred micrometers) to very fine particles (less than one micrometer).
  • Adaptability: The filtration fineness can be varied by adjusting the fiber size and the density of the fleece to meet the specific requirements of the application.
  • Efficiency: Higher filtration fineness generally means higher filtration efficiency, as smaller particles can be retained. This is particularly important in applications where high purity is required, such as in the electronics or food industry.
  • Flow Rate: It is important to balance filtration fineness and flow rate. Very fine filtration can reduce flow, so the fleece must be designed to provide sufficient flow rate at the desired filtration fineness.

Advantages of Metal Fiber Fleece

  • Durability: The high strength and corrosion resistance of metal fiber fleece ensure a long lifespan, even under demanding conditions.
  • Maintenance Friendliness: Metal fiber fleece can be easily cleaned and reused, reducing operating costs and increasing efficiency.
