Development of a New Evaluation System of Frictional Static Charge

Abstract

The static charge (voltage) and it's decay curve of rubbed fabric are measured and recorded automatically by the newly developed KB system. The accuracy and reproducibility of the KB system have been compared with those of existing Rotary Static Tester and Faraday's Cage Method prescribed in the Japanese Industrial Standard (JIS). It has been proved that the KB system has higher accuracy, higher reproducibility and lower variation than those of the existing methods.
