<p>A method of producing non-woven elements made from a raw material comprising grass plants. A first intermediate product is made of per-prepared, damp natural fibers having a dry substance concentration of between 30%-50%, more preferably approximately 40%. The invention also relates to the production of a second intermediate product from the first intermediate product according to the following steps. The natural fibers are predried, thermoactive binding fibers are added thereto, additives are sprayed thereon and the order of the step can vary and/or individual steps may be carried out simultaneously with one another. Preferably, the raw material is silated grass and, in order to produce the first intermediate product, the raw material is defibered and the digestible components of the raw material are separated therefrom.</p> |
