Abstract

Fabrics containing regularly spread conductive fibres introduced into their structure may storage an electric charge, what results in a characteristic surface potential distribution. The brush, electrostatic discharges may occur when the grounded conductive object approaches to the charged fabric surface. A simplified, charged fabric-grounded object model is proposed. A metal sphere as the conductive object and a synthetic fabric with conductive yarn (forming regular cells) are considered. The analytical model allows to connect the energy Wrel, that can be released during the discharge, with geometry of the fabric-object system. The model has led to the power type relation between the energy Wrel and the cell diameter of a.
