(FR) MATÉRIAUX CONTENANT DE LA CELLULOSE
Abstract
(EN)
Disclosed is a process for solubilising cellulose and coagulating the resulting solution to form a cellulose-containing material. The process comprises contacting a cellulose source with a solvent comprising zinc ions and formic acid to provide a solution, coagulating the solution to provide a solid material, treating the solid material, and isolating the solid material after treatment, to provide the cellulose-containing material. The process can further comprise solubilising protein and coagulating the resulting solution to form a cellulose/protein-containing material. The cellulose-containing materials and cellulose/protein-containing materials can be produced, for example, as reconstituted fibres and films.

L'invention concerne un procédé de solubilisation de cellulose et de coagulation de la solution obtenue permettant de former un matériau contenant de la cellulose. Le procédé consiste à mettre en contact une source de cellulose avec un solvant comprenant des ions zinc et de l'acide formique afin de fournir une solution, à coaguler la solution afin de fournir un matériau solide, à traiter le matériau solide, et à isoler le matériau solide après traitement, afin de fournir le matériau contenant de la cellulose. Le procédé peut en outre consister à solubiliser une protéine et à coaguler la solution obtenue, afin de former un matériau contenant de la cellulose/une protéine. Les matériaux contenant de la cellulose et les matériaux contenant de la cellulose/une protéine peuvent être produits par exemple sous forme de fibres reconstituées et de films.
