Aramid filament yarn provided with a conductive finish

摘要

The invention pertains to an aramid filament yarn provided with a finish comprising >1.5 wt. % of an organic substance with a conductivity of >4 mS/cm, measured as a 50 wt. % finish composition in water at 20° C., having a specific electric resistance of the yarn <2.5.10⁴ Ohm.cm, and to a method of making said yarn. Further, the invention pertains to the use of said finish for making conductive cables, particularly for making elevator cables.
