ABSTRACT The invention relates to reinforcing and/or process fibers based on plant fibers, obtainable thereby that plant fibers from which the wood components have been removed are treated with an aqueous solution of at least one metal compound selected among metal oxides, hydroxides, carbonates, sulfates, thiosulfates, sulfites, silicates or phosphates, subsequently washed and treated with an inorganic or organic binding agent or the fibers which have not been washed are neutralized with a mineral acid or that plant fibers from which the wood components have been removed are treated with an oxidation agent or that non-pretreated plant fibers are treated at 250 to 350°C with the controlled addition of air so that carbonization of the fibers takes place.
