ABSTRACT:
Process of silvering articles such as textile articles in order to make them conductive and the articles silvered by this process.
The articles are subjected to the action of a reducing agent which swells the substrate and then to the action of an ammoniacal silver nitrate solution. When a polyamide is used as a substrate, a polyphenol is an acceptable reducing agent. Yarns and fibers treated by the process can be used for the manufacture of floor coverings, wall coverings, and articles of clothing as well as for the manufacture of heating articles.
