1. Process for producing a fibrous composition, which contains a first component which comprises vegetable fibres and a second component that consists of a synthetic, electrically conductive polymer, according to which method:

  • the vegetable fibres comprise porous, loose and separate fibres, and the electrically conductive polymer used is an independently electrically conductive polymer which has been doped in order to generate charge carriers in the polymeric material, and the synthetic polymer is produced by in situ -polymerization within the fibres and on their surfaces, and whereby the electrically conductive polymers are attached so firmly to the fibres that they cannot substantially be washed out by water, characterized by using as a doping agent an organic sulphonic acid, which is allowed to absorb into fibres in an aqueous medium, and then a monomer corresponding to the polymer is brought into contact with the fibres and polymerized.
