The main purpose
Under laboratory conditions, evaluate the electrostatic characteristics of the fabric after it is charged in the form of friction, that is, test the surface density of the fabric.
Instrument characteristics
Rub the sample with the specified friction material, after charging the sample, measure the potential of the sample after putting it into the Faraday cylinder, and then convert it to the amount of charge per unit area.
1. The measuring device consists of a friction device and a potential measuring device.
2. The friction device includes a friction rod, a backing plate, a cushion seat and an insulating rod.
3. The potential measuring device is composed of Faraday tube, capacitor and potentiometer.
Technical index
1. Measuring range of electrostatic charge: ±0.001μC -9.999μC
2. The friction cloth is nylon or acrylic, the size is: 400mm×450mm
3. Three pieces of sample in warp and weft directions, sample size: 250mm×350mm
