Title (EN) METAL-CROSSLINKABLE OXIDIZED CELLULOSE-CONTAINING FIBROUS MATERIALS AND PRODUCTS MADE THEREFROM
(FR) MATIERES FIBREUSES CONTENANT DU CELLULOSE, OXYDEES ET RETICULABLES PAR METAUX, AINSI QUE PRODUITS CORRESPONDANTS
Abstract:
(EN) The present invention relates to crosslinked cellulose-containing fibrous material, wherein hydroxy groups are oxidized at the C(6) of glucose units of the cellulose into aldehyde and/or carboxy groups crosslinked with a metal-containing crosslinking agent selected from transition metals of groups IVa (preferably Zr), Va VIa, VIIa and VIIIa, aluminum and zinc; and a paper or nonwoven (product), e.g. tissue (product), which comprises this fibrous material. These paper or nonwoven (products) are distinguished by high wet and dry strength.
(FR) La présente invention concerne une matière fibreuse réticulée contenant du cellulose, dans laquelle les groupes hydroxy sont oxydés à C(6) des unités de glucose du cellulose pour former des groupes aldéhyde et/ou carboxy réticulés avec un agent de rétuculation contenant des métaux, sélectionné parmi les métaux de transition des groupes IVa (de préférence, Zr), Va, VIa, VII a et VIIIa, aluminium et zinc; et un papier ou un produit non tissé tel qu'un tissu qui comprend de la matière fibreuse. Ce papier ou ces non tissés se distinguent par une résistance élevée à l'état humide et sec.
