Product Item: Polyester Anti-static Filter Felt
Product Introduction: Generally, if industrial dust achieves the certain consistence (explosive limit), it may explode when it meets anti-static flame or outside ignition. For example: flour powder, chemical dust, coal dust and so on, if they meet flame there will be risk of explosion. In the bag dedusting industry, these types of dust request filter bags with anti-static function. Our company adopts advanced overseas technique, and develops and products of anti- static needle punched felt and woven filter fabric according to the special demands.
Besides the craft of ordinary needle punched felt, it also requests anti-static scrim fabric or directly blends the electric conductive fiber or conductive material in the ordinary synthetic fiber. Our company can produce these two types of anti-static filter felt. Our company has reached the leading position in producing anti- static needle punched felt and filters cloth and has passed the related tests by authoritative departments.
Property Index:
1.Blended polyester anti-static needle punched felt
During the production, we proportionally add electric conduction or antic- static fiber to needle punched felt. It is prevalent in the world at present. It generally adopts the carbon fiber or the stainless steel fiber.

2.Basic scrim anti-static needle punched felt
It adopts the anti-static woven fabric for scrim. While weaving scrim, we add the conductive fiber in the warp direction to make the base scrim enable anti-static function. After forming needle punched felts, this function that can be extended to the felt. Our factory generally adopts the conductive fiber of stainless steel. This type is economical.
