Abstract

L'invention concerne un procédé pour préparer de la cellulose, pouvant être façonnée et des produits façonnés en cellulose. Pour préparer un produit en cellulose précipitée, on dissout de la cellulose dans un solvant contenant un N-oxyde d'amine tertiaire qui est de préférence le N-oxyde de N,N,N-triéthylamine ou un N-oxyde d'amine tertiaire ayant une structure moléculaire cyclique ou pseudo-cyclique et de l'eau et on précipite la cellulose avec de l'eau ou un autre non solvant de la cellulose; on peut ajuster la teneur en eau de la solution à une valeur quelconque d'au plus environ 29 % en poids et de préférence comprise entre 1,4 % et 29 % en poids (zone hachurée de la figure), la quantité d'eau incorporée au solvant diminue pratiquement de façon linéaire avec l'accroissement de la quantité de cellulose dissoute. L'invention s'applique en particulier à des solutions pratiquement dépourvues de cellulose non dissoute et de N-oxyde d'amine tertiaire solide convenant au filage, à l'extrusion ou au moulage, à une température inférieure au point de fusion du N-oxyde d'amine tertiaire.
