Abstract: The present invention provides compositions, useful for making lyocell fibers, having a high hemicellulose content, a low lignin content and including cellulose that has a low average degree of polymerization (D.P.). Further, the present invention provides processes for making compositions, useful for making lyocell fibers, having a high hemicellulose content, a low lignin content and including cellulose that has a low average degree of polymerization. The present invention also provides lyocell fibers containing a high proportion of hemicellulose. Further, the lyocell fibers of the present invention have enhanced dye-binding properties and a reduced tendency to fibrillate.
