What is anti-static fabric?

The static electricity on the insulator surface can disappear in three ways:

(1) disappear through the air (mist);

(2) disappear along the surface;

(3) disappear through the insulator body.

Elimination of static electricity through the air, mainly rely on the opposite sign in the air of charged particles flying with the surface of the insulator electrostatic or charged particles to obtain kinetic energy and flying. The use of cutting-edge discharge principle, made of high-voltage corona static eliminator, has been in the chemical fiber production applications.

The rate at which static electricity disappears along the surface of the insulator depends on the size of the surface resistivity of the insulator. Increase the humidity of the air can be hydrophilic

The surface of the insulator forms a continuous water film, which, coupled with the dissolution of CO2 and other impurities in the air, greatly enhances the surface conductivity. A further approach is to use antistatic agents, mainly ionic or non-ionic surfactants.

Electrostatic charge through the insulator body leakage rate, mainly depends on the size of the insulator resistivity, in general, when the polymer resistance is less than 107Ω · m, the electrostatic charge will soon leak out. In order to increase the volume conductivity of the polymer, the most convenient way is to add carbon black, metal powder or conductive fibers.

Fiber polymer material is theoretically the insulator, but the actual fiber conductivity is higher than the theoretical estimate, because the fiber is not a pure polymer material, which contains water, impurities and other low molecular weight substances, fiber conduction depends mainly on the fiber Of the appendages, followed by the fiber itself and the conductivity of the external conditions of the role. In the surface of the ionizing material with higher conductivity and water vapor pressure greater circumstances, the conductivity of the fiber will be greatly enhanced.
