Abstract The present disclosure relates to a continuous process for preparing hydrophobic regenerated cellulosic fiber. Said process comprises treating never-dried cellulosic fiber with a hydrophobic composition comprising 0.05 2.5 weight % of an alkyl ketene dimer based on weight of cellulose. The alkyl ketene dimer has a formula I: wherein both R1 and R2 are hydrocarbon groups having 8-40 carbon atoms and which can be both, saturated or unsaturated, straight-chained or branched. The hydrophobic composition further comprises 0.02 - 1 weight % of a cationic polymer based on weight of cellulose. After treatment with the hydrophobic composition, the treated fiber is subjected to a drying step to form hydrophobic regenerated cellulose fiber. La présente divulgation concerne un procédé continu de préparation de fibre cellulosique régénérée hydrophobe. Ledit procédé comprend le traitement de fibre cellulosique jamais séchée avec une composition hydrophobe comprenant de 0,05 à 2,5 % en poids d'un dimère d'alkyle cétène sur la base du poids de la cellulose. Le dimère d'alkyle cétène a une formule I : dans laquelle R1 et R2 sont des groupes hydrocarbonés ayant de 8 à 40 atomes de carbone et qui peuvent être tous les deux saturés ou insaturés, linéaires ou ramifiés. La composition hydrophobe comprend en outre 0,02 à 1 % en poids d'un polymère cationique sur la base du poids de cellulose. Après le traitement avec la composition hydrophobe, la fibre traitée est soumise à une étape de séchage pour former une fibre de cellulose régénérée hydrophobe.
