Antistatic needle punched filter felt is usually used in situations where it is necessary to filter tiny particles in the air or liquid, while also requiring the product to prevent static electricity accumulation. This type of filter felt usually uses special fiber materials or adds antistatic agents to ensure that during the filtration process, static electricity will not absorb more particles or cause harm to the product.

We use leading technology in the Anti-static needle punched filter felt and guarantee the stability of our products:

  • Material: Polyester needle felt.

Description

Why use Anti-static Needle Felt Filter Cloth?

Usually, when the concentration of industrial dust reaches a certain level (that is, the explosion limit), it is very easy to cause explosion and fire if it encounters factors such as electrostatic discharge sparks, such as: flour dust, chemical dust, coal dust, etc. If these dusts need to be collected by cloth bags, the manufactured filter bags are required to have anti-static function. In addition to the process of producing ordinary needle felt, the production of antistatic filter material also requires the incorporation of conductive fibers into the warp yarn of the base fabric for the production of needle felt or the mixing of conductive fibers into chemical fibers.

Comparison of properties of different anti-static needle felt

Polypropylene (PP) with Conductive Fibers High Up to 90*C (194°F) Excellent Moderate Moderate
Polyimide (P84) Moderate Up to 260*C (500°F) Very Good High High
PTFE (Polytetrafluoroethylene) High Up to 250*C (482°F) Excellent High High
Aramid (Nomex) Moderate Up to 200*C (392°F) Good High High

Polyester

anti-static needle felt has a wide range of uses in industrial applications. It has the following advantages:

  • Excellent antistatic performance: Polyester antistatic needle felt has good antistatic performance through special process treatment or adding antistatic materials. It can effectively prevent static electricity accumulation and discharge, and is suitable for industrial environments that require antistatic.
  • Wear resistance and durability: Polyester needle felt is made of polyester fiber, which has excellent wear resistance and durability. It is not easy to wear or deform after long-term use, and is suitable for long-term work in high-intensity use environments.
  • Strong chemical stability: Polyester has good chemical stability, good acid and alkali resistance, and is not easily corroded by chemical substances. It is suitable for filtration and separation in a variety of industrial environments.
