Disclosed is a process for treating cellulosic fibers using an alkali metal hydroxide. The process first prepares the cellulosic fibers as a high consistency mixture with water and then adds an alkali metal hydroxide. The high consistency process is quite efficient and has been found to produce cellulosic fibers that are essentially uniformly treated. Also disclosed is a handsheet prepared from the treated cellulosic fibers for use is disposable absorbent products.

L'invention concerne un procédé permettant de traiter des fibres de cellulose par un hydroxyde alcalin. Selon le procédé, on prépare les fibres de cellulose de façon à obtenir un mélange à haute concentration avec de l'eau, puis on ajoute un hydroxyde alcalin. Ce procédé à haute concentration est très efficace et s'est révélé produire des fibres de cellulose traitées de manière sensiblement uniforme. L'invention concerne également une feuille d'essai préparée à partir des fibres de cellulose traitées et destinée à être utilisée dans des produits absorbants jetables.
