Polyester anti-static needle felt (blended with electric fiber)
According to the need of coal milling collecting dust of blast furnace gas, cement plant and other industries at domestic market, we absorbed foreign technology, then developed and produced the anti-static filter cloth.
It needs not only the technology of common needle punched felt, but also combining the conducting fiber into the transversal yarn in the needle punched felt base cloth or the conducting fiber and conducting material into the chemical fiber. Our factory could produce both of anti-static filter cloth.
The specification of our anti-static needle felt and filter cloth takes a leading position at home, otherwise, the authority department has already tested them.
