Metal Fibre Blending for Antistatic Textiles
topic
Antistatic textile fabrics blend 0.5 to 2 percent by count of stainless steel or carbon fibres into polyester and cotton yarns at defined spacing intervals of 5 to 10 millimetres to create a conductive grid that dissipates static charge through the fabric, achieving surface resistivity below 10 to the 9th power ohms per square and body voltage below 2000 volts peak during simulated walking under EN 1149 test conditions.
Role
Prevents static charge accumulation on workers in explosive atmosphere zones classified ATEX Zone 0, 1, and 2 by integrating sufficient conductive fibre into garment fabric to continuously dissipate triboelectric charge generation below ignition threshold levels, satisfying EN 1149-5 garment system requirements without compromising fabric aesthetics, comfort, or textile processability.
