product detail

What is an Anti-static water and oil repellent polyester filter bag?

The anti-static filter bags are made of anti-static needle felt. In the production process of needle punched felt. There are two anti-static procedures that can be used to manufacture anti-static needle punched felt.

The first one is to mix conductive fiber yarn with the warp of the base fabric .The second procedure is to mix conductive materials such as conductive fibers in chemical fibers.

These two types of anti-static filter fabrics have excellent performance. SFFILTECH offers both of these production procedures for anti-static filter bags. The product that shown in the picture is made using the first production procedure. The anti-static filter bag is made of different materials such as polyester, aramid, P84, PPS etc. Polyester anti-static filter bags are most commonly used in the market.

Afterwards the Anti-static filter bag receives water and oil repellent treatment same the treatment used to manufacture water and oil repellent needle punched felt. Thus combining the functionality of anti-static filter bag with water repellent and oil resistant filter bag.

What is the special production procedure for Anti-static water and oil repellent polyester filter bags?

The anti-static water repellent and oil resistant polyester filter bag is made of polyester filament and conductive fibers through a water repellent and oil resistant treatment process. The most traditional polyester needle felt on the market only requires needling, singeing, heat setting, and rolling before use. However, in complex working conditions with high filtration and other specific requirements. Special production procedure is required to improve the performance of filter bags.

Filter bags can be treated with singeing, calendaring, water and oil repellent coating, PTFE impregnation and lamination as per customers demand and configuration.

FAQ
    • Q
      What is “Striped Anti-Static” technology? How does it work?
      A
      “Striped Anti-Static” is a highly effective conductive technology. Black conductive yarns are woven into the base fabric of the filter material at regular intervals along a specific direction (typically the warp direction), forming distinct conductive stripes on the filter surface. These stripes create a complete, low-resistance conductive network within the filter bag, rapidly guiding and dissipating static charges generated during filtration to completely eliminate static buildup.
    • Q
      What are the unique advantages of striped anti-static compared to blended anti-static?
      A
      The primary advantage of the striped anti-static structure lies in its clearer, more efficient, and cost-effective conductive pathways. It achieves optimal charge dissipation with minimal conductive material while creating a visible “safety indicator” on the fabric surface. This facilitates customer identification and ensures proper grounding connections during installation.
    • Q
      How does this product simultaneously achieve anti-static and water/oil-repellent functions? Do they interfere with each other?
      A
      These are two independent and complementary advanced processes. First, conductive yarns are woven into the base fabric during manufacturing to provide permanent anti-static properties. Then, the finished filter material undergoes impregnation or coating for water and oil repellency (hydrophobic/oleophobic) post-treatment. This treatment occurs at the molecular level without clogging conductive fibers or filter pores, allowing both functions to operate synergistically without interference.
    • Q
      For which operating conditions are these multifunctional filter bags most suitable?
      A
      They are specifically designed for complex environments involving flammable/explosive materials, high humidity, or oil mist. Typical applications include:
      - Moist food dusts such as grain, flour, and starch.
      - Explosion-risk conditions with potential condensation, e.g., pulverized coal preparation and pulverized coal injection systems.
      - Process points in chemical and pharmaceutical industries requiring both explosion protection and handling of hygroscopic or oil-laden dust.
      - Dust collection systems in foundries and metallurgical workshops with unstable humidity levels.
    • Q
      What specific benefits does the water and oil repellency provide?
      A
      The water and oil repellency (hydrophobic and oleophobic) function enables:
      - Prevent bag clogging: Effectively resist moisture and oil mist penetration, preventing dust from caking on filter bag surfaces.
      - Stabilize resistance: Maintain filter media air permeability for smoother equipment operation.
      - Facilitate cleaning: Dust cannot firmly bond with filter fibers, enabling more thorough pulse cleaning.
      - Extend lifespan: Reduce filter bag caking and corrosion caused by moisture and oil contamination.
