Abstract

La présente invention concerne un procédé pour produire des fibres de cellulose modifiées à partir d'une solution de cellulose dans du N-méthylmorpholine-N-oxyde. Ce procédé consiste à mélanger de la cellulose avec du N-méthylmorpholine-N-oxyde aqueux, à l'évaporer, puis à filtrer la solution de filage, qui est ensuite passée à travers les trous dans la filière, jusque dans le bain de filage aqueux, et enfin à rincer, sécher et conditionner. Cette invention est caractérisée en ce que l'on ajoute à la cellulose, au solvant ou à la solution de filage des substances de modification, telles que des oxydes céramiques, des oxydes métalliques ou des mélanges de ceux-ci, contenant si nécessaire des agents tensioactifs supplémentaires, du carbone, si nécessaire modifiés avec de l'argent, des agents bactéricides, des indicateurs acide-base ou des colorants thermochromiques à séparation nanomoléculaire ou supramoléculaire.
