ABSTRACT:
Textiles, preferably yarns and fibers, based on synthetic polymers, with permanent conducting properties, which possess, on the surface, a uniform continuous layer consisting of at least 3% of copper sulphide, the composition of which is such that the atomic ratio Cu/S is between 1.5 and 2, and preferably more than 1.7, and of which the ratio R/R.sub.o is between 1 and 10, R being the electrical resistance after treatment for 400 hours at 60.degree. C. and at a humidity of 70%, and R.sub.o being the initial resistance of the treated textile. The synthetic polymer is based on polyamide or polyester, or is an aromatic polyamide or a polyamide-imide. Processes for the manufacture of these textiles and textile articles with permanent conducting properties, such as floor/wall coverings, containing between 0.01 and 5% of the treated textiles, are also disclosed.
