The present invention provides compositions, useful for making lyocell fibers, having a high hemicellulose content, a low copper number and including cellulose that has a low average degree of polymerization (D.P.) and a narrow molecular weight distribution. Further, the present invention provides processes for making compositions, useful for making lyocell fibers, having a high hemicellulose content, a low copper number and including cellulose that has a low average degree of polymerization and a narrow molecular weight distribution. The present invention also provides lyocell fibers containing a high proportion of hemicellulose.
L'invention concerne des compositions utiles pour produire des fibres Lyocell et présentant une haute concentration d'hémicellulose, un faible indice de cuivre et de la cellulose qui a un faible degré moyen de polymérisation et une répartition étroite de la masse moléculaire. La présente invention concerne en outre des procédés pour réaliser des compositions utiles pour produire des fibres Lyocell et présentant une haute concentration d'hémicellulose, un faible indice de cuivre et de la cellulose qui a un faible degré moyen de polymérisation et une répartition étroite de la masse moléculaire. Ladite invention porte également sur des fibres Lyocell constituées d'un pourcentage important d'hémicellulose.
