Abstract:

This paper emphasises the practical aspect of the maximum surface potential of fabric. The phenomenon of back discharges (back corona) was described, and the possibility of generating these discharges on polymeric fabrics was practically confirmed. The results obtained showed that in the case of high volume-resistivity fabrics the back discharges may be the basic mechanism responsible for the limitation of the maximum value of the surface potential of fabrics placed on conducting surfaces. The limited application of Paschen’s law for determining the surface’s potential maximum value was also shown.
