Abstract (en)
[origin: WO2020100097A1] The present invention relates to a method for hydrophobizing a cellulose substrate (1), which comprising a first side and a second side, which faces away from the first side, the method comprising the steps of: -drying the cellulose substrate to a dry content above 80%, preferably above 85%; -providing a fatty acid halide in spray form; -converting said fatty acid halide in spray form into vaporized fatty acid halide; and -guiding said vaporized fatty acid halide to contact the first side of the cellulose substrate, and at least partially penetrate the cellulose substrate.
