Fabric materials offer an effective means for the removal of dust from gas streams. The fabric is arranged in the equipment in such a way that the dust laden gas has to pass through the small openings of the fabric. Due to different physical phenomena, the dust particles impinge on the surface of the fabric material and adhere to it. Fig. 1 shows limestone particles adhering to a fiber; the particle size is between 3 and 10 μm; the diameter of the fiber is about 50 μm . A photograph of a needle felt, that was exposed to tobacco smoke for a very short time, is shown in Fig. 2.
