The present invention relates to a modified fiber product and a method of producing same. According to the method, the cellulosic raw material is formed into a fiber suspension, into which components modifying the properties of the fibers are added, subsequent to which the fibrous material is dried in connection with, for example, web forming. According to the invention, alkyl derivative of cellulose is mixed into the fiber suspension in alkaline conditions, the derivative being at least partly dissolved in water, and the derivative is allowed to be sorbed into the fibrous material prior to drying such that the sorbed cellulose derivative can not be washed off with water. The strength properties or the water retention of paper and paperboard products can be improved by using the invention.

La présente invention concerne un produit fibreux modifié et un de ses procédés de production. Selon ce procédé, on obtient à partir d'une matière première cellulosique une suspension fibreuse, dans laquelle on ajoute des composants modifiant les propriétés des fibres. On sèche ensuite la matière fibreuse, par exemple, en association avec la formation de bande continue. Selon l'invention, on mélange à la suspension fibreuse en milieu alcalin un dérivé alkylé de cellulose, ce dérivé étant au moins partiellement dissous dans l'eau. Ce dérivé est absorbé par la matière fibreuse avant le séchage pour que le dérivé de cellulose absorbé ne puisse pas être délavé à l'eau. L'utilisation de cette invention permet d'améliorer les propriétés de résistance ou la rétention d'eau des produits en papier et en carton.
