Metal fiber production and products
To produce fine fibers, several copper-coated wires are first bundled into a tube which is drawn through a die to further reduce its diameter.

The covering tube and copper are then dissolved in acid, resulting in individual long metal fibers. These are transformed into knitted, braided, woven or nonwoven products that resist high temperatures or provide electrostatic protection or electromagnetic shielding. Fibers can also be produced using other processes.
