Beschreibung
Zusammenfassung:	A method of producing dimensionally stable paper and/or paperboard products by treating a hygroreactive cellulosic fiber matrix with a hydrophobic sizing agent solution; and drying the treated fibers using heat and/or pressure so that the hydrophobic sizing agent penetrates the fiber matrix making it hydrophobic. L'invention concerne un procédé de production d'articles en papier et/ou en carton présentant une stabilité dimensionnelle, ce procédé consistant tout d'abord à traiter une matrice de fibres cellulosiques réagissant à l'humidité avec une colle hydrophobe. Ce procédé consiste ensuite à sécher les fibres traitées, de sorte que grâce à la chaleur et/ou à la pression, ladite colle hydrophobe pénètre dans la matrice fibreuse, la rendant ainsi hydrophobe.
