Abstract: The invention is lyocell fiber characterized by a pebbled surface as seen at high magnification and having a variable cross section and diameter along and between fibers. The fiber is produced by centrifugal spinning, melt blowing or its spunbonding variation. The fibers can be made in the microdenier range with average weights as low as one denier or less. The fibers have inherently low gloss and can be formed into tight yarns for making fabrics of very soft hand. Alternatively, the fibers can be formed into selfbonded nonwoven fabrics.
Abstract translation: 本发明是以高放大倍率观察到的具有卵形表面的莱赛尔纤维，并且在纤维之间和之间具有可变的横截面和直径。 纤维通过离心纺丝，熔融吹塑或其纺粘变体产生。 纤维可以在平均重量低至1旦或更小的微米范围内制成。 纤维具有固有的低光泽度，并且可以形成紧纱，用于制造非常柔软的手的织物。 或者，纤维可以形成为无粘结无纺织物。

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.
