METHOD FOR HYDROPHOBISATION OF CELLULOSE SUBSTRATE

摘要

FIELD: technological processes.;SUBSTANCE: method for hydrophobisation of cellulose substrate (1) having a first side and a second side facing away from a first side. Method includes steps of drying cellulose substrate (1) to dryness of more than 80 %, preferably more than 85 %, adding an evaporated fatty acid halide to a first side of the cellulose substrate and at the same time vacuum suction from the second side of the cellulose substrate so that the evaporated fatty acid penetrates through cellulose substrate (1) in a certain direction.;EFFECT: disclosed is a method for hydrophobisation of a cellulose substrate.;10 cl, 2 dwg
