Most of the time, it isn't ! An antistatic fabric must have metal fibers or carbon fibers. It must therefore contain grey or black fibers.
Are your batch centrifuge grounded ? In theory yes, but how could they eliminate electrostatic charges through a non conductive bag ?
As the grid stands behind the fabric, the issue remains the same !
It is mandatory if your bag fabric is antistatic, otherwise ...
We have some antistatic fabrics, especially a PP multifilament including 316L stainless steel fibers, thick enough and tight enough to replace the commonly used fabrics.
