1. Conductive fiber:
A general term for fibers made of conductive materials or sub-conductive materials such as metal or conductive organic matter and antistatic agents in whole or in part.
It is generally understood that the conductivity of the conductive fiber>10-7Ω·cm, or the resistivity<107Ω·cm.
2. Anti-static fiber
A general term for a type of fiber produced by physical, chemical or physical chemical methods and processes to meet the requirements of static electricity (such as fibers made with antistatic agents or treated with antistatic agents).
3. Electrostatic conductor
Under any conditions, materials with volume resistivity ≤106Ω·cm (ie, conductivity ≥10-6s/m) and solid surfaces with surface resistivity ≤107Ω.
4. Electrostatic subconductor
Under any conditions: objects with volume resistivity ≥ 106Ω·m but less than 1010Ω·m.
Solid surface with surface resistivity>107Ω and <1011Ω.
5. Electrostatic non-conductor
Under any conditions, materials with volume resistivity ≥1010Ω·m (ie, electrical conductivity ≤10-10s/m) and solid surfaces with surface resistivity ≥1011Ω.
6. Surface resistance and surface resistivity
After a given energization time, the ratio of the DC voltage applied to the two electrodes on the surface of the material to the current between the two electrodes is called surface resistance, and the possible polarization on the two electrodes is ignored.
Surface resistivity is a physical quantity that characterizes the surface conductivity of an object. It is the resistance value between two opposite sides of a square material, independent of the thickness of the object and the size of the square.
Note: The unit of surface resistivity is ohm (Ω).
7. Volume resistance and volume resistivity
After a given energization time, the ratio of the direct current voltage between the two lead electrodes that are in contact on two opposite surfaces of a piece of material to the current between the two electrodes is called the volume resistance. The polarization phenomenon is ignored.
Volume resistivity is a physical quantity that characterizes the electrical conductivity of an object. It is the resistivity of the material per unit cross-sectional area and unit length.
Note: The unit of volume resistivity is ohm·m (Ω·m)
