Abstract
The present invention is directed to lyocell fibers having a high hemicellulose content of at least 5%, a low lignin content as measured by a kappa number less than 2.0 and including cellulose that has a low average degree of polymerization (D.P.) in the range of 200 to 1100. Further, the lyocell fibers of the present invention have enhanced dye-binding properties and a reduced tendency to fibrillate.
