A METHOD FOR PRODUCING A CELLULOSE PRODUCT AND A CELLULOSE PRODUCT

A method for producing a cellulose product from an air-formed cellulose blank structure comprising the steps; providing a cellulose blank structure which is air-formed from cellulose fibres; applying, in a first application step (SA1), an alkyl ketene dimer (AKD) dispersion to the cellulose blank st...

Beschreibung
Zusammenfassung:	A method for producing a cellulose product from an air-formed cellulose blank structure comprising the steps; providing a cellulose blank structure which is air-formed from cellulose fibres; applying, in a first application step (SA1), an alkyl ketene dimer (AKD) dispersion to the cellulose blank structure, and applying, in a second application step (SA2) a latex dispersion to the cellulose blank structure arranging the cellulose blank structure with the applied alkyl ketene dimer (AKD) dispersion and latex dispersion in a forming mould; heating the cellulose blank structure to a forming temperature (TF) in the range of 100° C. to 300° C., and forming the cellulose product from the cellulose blank structure in the forming mould, by pressing the heated cellulose blank structure with the applied alkyl ketene dimer (AKD) dispersion and latex dispersion with a forming pressure (PF) of at least 1 MPa, preferably 4-20 MPa.
