Abstract

A process for the production of metal coated melamine-formaldehyde fibers is disclosed. Prior to coating, the fibers are first activated. Activation consists of applying a metal layer to the fibers by reducing a water soluble cobalt, copper or nickel salt with either: 1) a less noble metal or metal salt or 2) a hydride compound and a complexing agent. The desired metal coating is then applied to the pretreated fibers by reducing a water soluble salt of the metal with a reducing agent in the presence of a complexing agent.
