It is necessary to study the electrification of engineering materials. The increased uses of polymeric materials raised the importance of studying that effect. It is well known that when two different materials contact each other, they may get charged. Electrostatic charges (ESC) generated from friction of engineering materials have a negative effect in the health of the peoples. In football, goalkeeper needs gloves to keep his hand safe and enhance his ability to catch the ball. The aim of the present work is to make quantitative measurements of the electrostatic charge generated from the sliding of the ball against the glove surface. The gripping ability of the glove is one of the main factors to evaluate its quality. It should provide an adequate grip and tactile response under a wide range of conditions. The other factor is the health of goalkeepers which is of great concern. The materials of the ball as well as the gloves of goalkeepers should be selected on the basis of generation of low ESC. The experiments showed that ESC generated on the glove surface could be controlled by proper selection of the materials of appropriate surface qualities for practical use. ESC values generated from the sliding of the ball on the gloves of the goalkeeper can be doubled and accumulated so that they affect his physical condition during the match.
