I came across a shirt made out of this in the goodwill. It turns out the fabric is very hardous to make so there are many rules for importing it. I actually own a lot of Nomex clothing with carbon in them to make them antistatic. These are designed for power line workers. But I wonder if the carbon can be washed out or nullified by chemical reactions. If you can see the copper color it should work. It may be an effective Farraday cage. Every little bit helps.
