In this research work, the woven fabric samples of cotton, polyester PC blend, glass and silk materials have been selected to analyze the electrostatic discharge behavior of various woven fabrics using electrostatic discharge tester. The electrostatic discharge is mainly depends upon various controlled factors of electrostatic discharge tester hence, the controlled factors of number of rubbing cycle (20, 30 and 40 strokes), pressure (100,150 and 200 gms), speed (10, 20 and 30 mpm) were considered and analyzed the electrostatic discharge behaviors of various woven fabrics under various temperature and relative humidity using Box Behnken design and regression analysis. It was found that the glass and silk woven fabric have greatest tendency to give up electrons and gain a positive electrical charge but in case of polyester woven fabric have the greatest tendency to attract electrons and gain a negative electrical charge. It was observed that glass woven fabrics have more electrostatic discharge value than the polyester, PC blend, silk and cotton woven fabrics and it was also found that higher number of rubbing cycle, pressure and speed have significant effects on the electrostatic discharge properties of various types of woven fabrics.
