Electrostatic flocking is applied to general goods, clothes and to various parts of industrial products. The object of this work is to develop an anti-electrostatic mat using an electrostatic flocking technology. Conductive flock and conductive adhesive are necessary as the flocking materials to make the anti-electrostatic mat. Electrostatic flocking proves to be difficult if the flock has a low resistance, this is because the high-voltage power supply tends to get cut off frequently. Lowering of flocking intensity becomes troublesome if the conductive carbon powder is added to the flocking adhesive, because the carbon powder causes a lowering of the gluing intensity. These two tasks were discussed and solutions were discovered. We made the anti-electrostatic mat using a conductive adhesive which contains carbon powder with a ratio of 25% and a mixed flock which contains a conductive flock with a ratio of 5%. The flocking conditions included a flocking distance of 10cm and a flocking voltage of 25kV. The resistance of the anti-electrostatic flocking mat is 105Ω and the electrostatic potential of the human body employing a walking method is under 1.1kV. These measurement results show that the mat have an anti-electrostatic function.
