Abstract: A non-woven fabric of electret fibres is predominantly made of a fibre-forming polymer or polycondensate and 0.01-30, pref. 0.01-10, and esp. 0.1-5, wt.% of an organic or organometallic charge control agent. The fabric contains ≥ 2 sorts of electret fibres which are made from different materials. Also claims dust filters and dust wiping cloth made from the non-woven fabric; and the use of the non-woven fabric in fire dust filters and in dust wiping cloths.
