Why is surface resistivity important in textiles?

In contrast to many bulk materials, textiles have high porosity and often show anisotropy. Therefore, the surface resistivity is not a valuable indication in most of the cases; instead, the surface resistance per unit area is more critical. Preferably, the resistance per unit area should be given with direction.
