Zusammenfassung:Method for hydrophobing 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 a cellulose substrate (1) to a dry content above 80%, preferably above 85%,adding a vaporized fatty acid halide, to the first side of the cellulose substrate, and, at the same time perform vacuum sucking at the second side of the cellulose substrate, such that, the vaporized fatty acid penetrates the cellulose substrate (1) in a predetermined direction through the substrate. 用于使纤维素基底(1)疏水化的方法,所述纤维素基底(1)包括第侧和面向背离所述第侧的第二侧。所述方法包括如下步骤:将纤维素基底(1)干燥至高于80%、优选高于85%的干含量,将汽化的脂肪酸卤化物加至纤维素基底的第侧,和,同时在纤维素基底的第二侧进行真空抽吸,使得汽化的脂肪酸以通过基底的预定的方向穿透纤维素基底(1)。
