A plant substrate (I), made of predominantly fibers that are longer than 15mm and thinner than 7, preferably 3dtex, especially made of waxy raw materials, is new. A plant substrate (I), made of predominantly fibres that are longer than 15mm and thinner than 7, preferably 3dtex, especially made of waxy raw materials, is new. (I) is enclosed in an area of between 10 - 100kg per m<3>, so that the fibers are built in a vertical orientation with a constant thickness. The height of (I) and the presence of air holes with a radius of no more than 200 mu m forms a distinctive vertical capillary movement. (I) is fixed through thermal solidification with natural organic binding materials such as proteins, tannins, lignins and carbohydrates, or with binding fibers and/or other thermo- or duroplastic or soluble binding systems, or a mixture of these. (I) has a moisture storage capacity of at least 40 volume % and a minimum air storage capacity of at least 10 volume %, without additional moisture absorption from the total capillary storage and from the spaces and substances of the single fibers. |
