Abstract: A process for the manufacture of a triboelectrically charged nonwoven, wherein a fiber blend made of polyacrylnitrile fibers with a titer of ≦1.7 dtex and of polyolefine fibers with a titer of ≦1.7 dtex is freed from lubricating agents and antistatic agents by washing, is dried down to a moisture content of <1% by weight and is carded on a longitudinal or randomizing card into a triboelectrically charged web with a mass per area unit of 15-80 g/m2. This web is taken off by two simultaneously running rolls and a transfer roll, so that the web is laid on to a conveyor in machine direction, and bonded directly inside a bonding set, the unbonded web being forwarded via 1 to 3 points of transfer only.
