发明名称 Sawdust alkaline pulp having low average degree of polymerization values and method of producing the same
摘要 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.), wherein greater than 4% of pulp fibers have a length-weighted fiber length of less than 2.0 mm. 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 short fibers. The present invention also provides lyocell fibers and molded bodies made from the compositions. An advantage of the compositions are their quick dissolving nature.
