Antistatic how to identify the type of fabric

Antistatic fabric root ordinary fabric the same, but added a conductive wire.
Therefore, anti-static cloth to distinguish according to the following rules:
1) Base material polyester, nylon, polyvinyl alcohol, or composite
2) the structure of knitted fabric (minute number) weight thickness, woven (usually 1/1, 1/2) the structure and weft density.
3) the surface conduction type of yarn (each electrically conductive wire has a different structure of the material) and the density of mercerizing (0.5cm stripes, grids, etc. 0.25) and the surface friction resistance and voltage and its decay time.
4) the density of the material and the moisture vapor permeability capacity
