Abstract
Abstract A process for the production of metal-plated staple fibers comprising providing staple fibers having an areal weight of 0.5 to 5.0 kg/m2, activating said fibers by conventional means, and spraying an electroless metal-plating solution onto the activated fibers at a space velocity of 100 to 600m3 of the plating solution per m3 of the fibers per hour.
