Fabric yarn contains a certain proportion of conductive yarn which is made of a certain proportion of metallic oxide fibers or other conductive fibers blended with ordinary fibers. Its conductivity is higher than Japan's "Anti-Static Safety Guidance" requirement. The density of charge of antistatic fabric is less than 7uc/m2. It’s known as the "permanent" anti-static fabric. Also the performance of flame resistance can reach EN1161, EN11612 and NFPA2112 standards.
