A. Are Tyvek® IsoClean® garments anti-static or static dissipative? The fabric used to make Tyvek® IsoClean® garments is treated with a topical antistatic agent to help minimize static buildup and reduce nuisance garment cling. The topical antistat is water soluble, so antistatic performance is reduced in clean-processed garments. Sterilization may also impact anti-static performance. In situations where static dissipation level is a critical performance property, end-users should evaluate the performance of their entire ensemble, as worn, including outer garments, inner garments, footwear and other personal protective equipment (PPE). In order for any garment system to be static dissipative, it must be able to drain a charge buildup through proper grounding devices, such as, but not limited to, workstation grounding clips or static-dissipative floors.
