Method for producing a cellulose product

A method for producing a cellulose product from a multi-layer cellulose blank structure, wherein the method comprises the steps;

• forming the multi-layer cellulose blank structure from at least a first layer of dry-formed cellulose fibres and a second layer of a cellulose fibre web structure, through arranging the at least first layer and second layer in a superimposed relationship to each other and in the superimposed relationship arranging the at least first layer and second layer in contact with each other;
• arranging the multi-layer cellulose blank structure in a forming mould;
• and
• heating the multi-layer cellulose blank structure to a forming temperature in the range of 100° C. to 300° C.,
• characterized in that the first and second layers have a fiber composition of 100% cellulose fibers and are free from thermoplastic fibers, and that the method further comprises the step;
• forming the cellulose product from the multi-layer cellulose blank structure in the forming mould, by pressing the heated multi-layer cellulose blank structure with an isostatic forming pressure of at least 4 MPa, wherein the multi-layer cellulose blank structure is shaped into a three-dimensional fibre composite structure having a single-layer configuration, wherein the first layer of dry-formed cellulose fibres and/or the second layer comprises one or more additives that are altering the mechanical, hydrophobic, and/or oleophobic properties of the cellulose product, or that one or more additives that are altering the mechanical, hydrophobic, and/or oleophobic properties of the cellulose product are added to the formed multi-layer cellulose blank structure, wherein the first layer and/or the second layer and/or the multilayer cellulose blank structure has a material composition of 70-99.9% dry wt cellulose fibres and 0.1-30% dry wt of the one or more additives,
• wherein the one or more additives of the first layer are starch compounds, rosin compounds, butanetetracarboxylic acid, gelatin compounds, alkyl ketene dimer (AKD), Alkenyl Succinic Anhydride (ASA), wax compounds, silicon compounds, calcium compounds, and/or fluorocarbons.
