Abstract

ABSTRACT
Electrostatic charges building up on human skin and or clothes in direct contact with human body are very harmful and can create serious health problems. The electrostatic charge and friction coefficient of bare foot and foot wearing socks sliding against different types of flooring materials were investigated under dry sliding condition. The tested flooring materials were ceramic, marble, parquet, moquette and rubber.
 
It was found that rubber flooring showed the highest generated voltage among the tested floorings. The highest voltage values were displayed by polyester socks, while cotton socks showed the lowest one. This observation can confirm the necessity of careful selection of the flooring materials. Parquet flooring showed the lowest voltage among the all tested flooring, where the maximum voltage did not exceed 520 volts at 800 N load.  Friction coefficient displayed by sliding against rubber flooring represented the highest values of friction coefficient compared to the other tested floorings. Bare foot showed the highest values followed by cotton and polyester socks. The lowest values were 0.6 for polyester socks at 800 N.
 
Voltage generated from sliding against all the tested floorings significantly increased with increasing load. Bare foot conducts the electric static charge, while cotton and polyester socks as insulating materials could store the charge. It is expected that electrical field will be formed due the electric charge formed on the sock and floor surfaces.
