Patent

CA 2204412

The moulding, especially a fibre or foil, of cellulose regenerated by the amino-oxide process, is characterized in that the cellulose contains 0.02 to 30 % mass of a polyalkylene imine derivative. Besides the stabilisation of the moulding compound, the mouldings/fibres exhibit improved properties like anion exchange capacity, fungistatic properties and improved hydroblast resistance.

L'invention concerne un corps de moulage, notamment une fibre ou un film, en cellulose régénérée par un procédé faisant appel à l'aminoxyde, qui se caractérise en ce que la cellulose contient entre 0,02 et 30 % en poids d'un dérivé imine de polyalkylène. Outre la stabilisation de la matière de moulage, les propriétés des corps de moulage/fibres, telles que la capacité d'échange anionique, le pouvoir fongistatique et la résistance au dessablage par voie humide, sont améliorées.
