Because clothing usually is electrically insulated or isolated from the body, charges on clothing fabrics are not necessarily dissipated to the skin and then to ground. ESD jackets and lab coats offer protection from electrostatic fields generated by clothing on the user’s body. ESD garments are worn whenever static damage is a concern.
ESD jackets differ from common work garments because they contain a grid of conductive fibers imbedded throughout the garment. The grid creates a “Faraday Cage” effect around the body of the operator, that shields charges generated from the operator’s clothing that could damage devices that are sensitive to static electricity.

In industries such as electronics, aerospace, medical device, pharmaceutical and automotive, manufacturers place significant emphasis on the cleanliness of their products. The shrinking geometries of devices combined with the need for higher product yields have increased the demand for clean packaging materials over the last several decades.

We begin by discussing the particle contamination issues in gown up rooms. Operating personnel enter gown up rooms to prepare for entry into the final clean room environment where items are processed. Without any static mitigating techniques, the operators and their clothing are statically charged causing substantial particle attraction.
