The apparatus is suitable for the determination of the electrostatic properties of fibers, yarns, fabrics, carpets, decorative fabrics and other fabrics or various kinds of finished products in the laboratory. The main engine consists of corona discharge device and probe detector. The use of high voltage electric field is given, the fabric fixed time discharge, so that the fabric of electrostatic induction, electrostatic charge size, electrostatic pressure decay half-life, electrostatic residues detection, to display the measured fabric with antistatic property.
