Textile Yarns and Fibres, preferably on the basis of Synthetic Polymers with Permanent Conductive Properties, and the procedure for its manufacture

摘要

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/Ro is between 1 and 10, R being the electrical resistance after treatment for 400 hours at 60 DEG C. and at a humidity of 70%, and Ro 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.
