Abstract
Cette invention a trait à un procédé de traitement de fibres cellulosiques faisant intervenir un fractionnement thermomécanique à la vapeur qui permet de produire avantageusement des fibres cellulosiques modifiées faisant montre de caractéristiques souhaitées, notamment des valeurs de courbures à l'état humide. Ce procédé de fractionnement thermomécanique à la vapeur se révèle des plus satisfaisant, s'agissant de produire des fibres cellulosiques traitées de manière sensiblement homogène. L'invention concerne également une feuille de laboratoire produite à partir de fibres cellulosiques traitées à utiliser dans des articles absorbants jetables.
