Glossary: Antistatic Carpet

The term antistatic refers to a condition where static generation is inhibited when the antistatic material comes into frictional contact with another material—in flooring terms, inhibits static when people walk across the antistatic floor.

When referring specifically to carpet, the term “antistatic” has a slightly different meaning. Antistatic carpet is a generic term referring to any carpet product that generates less static electricity than standard carpet. Antistatic carpet is not conductive and cannot be grounded.

Illustration in three panels that explains the difference between standard low kv carpet, low kv carpet with permanent conductive fiber and ANSI/ESD compliant carpet tile. The first panel is headed “Standard Low kV carpet” and has an illustration of a thread cross section (labelled as such). The text underneath reads “Conductive fiber is buried inside each thread (elevation)”. Then follows an illustration showing a cropped leg/foot walking on carpet with a zoomed in section showing the shoe contacting the floor. At the bottom the text reads “Buried in the carpet thread, conductive fiber cannot make contact with the shoe, so there is no conductivity. Standard carpet tile cannot be grounded.” The second panel is headed “Low kV Carpet Tile with Permanent Conductive Fiber”. Underneath is an illustration showing the fiber integrated into the carpet weave (labelled thread cross section). The text underneath reads: “Conductive fiber is integrated into the fiber weave (elevation)”. Underneath is an illustration of a cropped leg/foot walking on the carpet. In a zoomed in close up, the fibers can be seen integrated into the thread. The text at the bottom reads: “The backing is insulate. Without a conductive backing, there is no path to ground. Even with the conductive fibers, the carpet cannot be grounded.” The third panel is headed “ANSI/ESD Compliant Carpet Tile”. Underneath is an illustration showing the fiber integrated into the carpet weave (labelled thread cross section). Below that is the text “Conductive fiber is integrated into the carpet weave (elevation). Underneath is an illustration of a cropped leg/foot walking across a carpet with the bottom layer showing as grounded (by the grounding symbol). In a zoomed in close up, the fibers can be seen integrated into the thread. At the bottom of the panel is the text: “ANSI/ESD compliant carpet tile provides four layers of conductivity. Under the conductive fiber is a conductive primary backing, a conductive pre-coat, and conductive fibreglass, with a static-dissipative PVC backing at the bottom.

Antistatic carpet usually contains bi-component yarns. The reason for specifying antistatic carpet is to establish a space that will be free of static shocks, or zaps. Most new antistatic carpet will prevent shocks as long as the relative humidity (RH) is above 25%.

Anti static carpets do not offer permanent static protection and should NOT be confused with conductive or ESD carpet.
