Abstract :
Propagating brush discharges (PBD), which are highly energetic and capable of igniting flammable gas, vapor and even dust cloud, occurring on an insulating thin film having electrically grounded anti-static fabrics for flexible intermediate bulk containers (FIBC) on its back side are observed and charge amounts relating to discharges are determined. It is found that thin metallic fiber woven on an insulating fabric drastically enhances the transferring of charge during a PBD presumably because of corona discharges emanating from the metallic fiber. Resistivity of fabric also greatly affects charge transferring. Finally, the incendivity of each mode of PBD is discussed
