A nonwoven cellulose fiber fabric (102), in particular made directly from a lyocell spinning solution (104), wherein the fabric (102) comprises a network of substantially infinite fibers (108) differing relative to to fiber diameter, so that a ratio between a larger fiber diameter and a smaller fiber diameter is greater than 1.5, in which those different from the fibers (108) are located at least partially in different layers (200 , 202) distinguishable, in which at least 80 mass percent of the fibers (108) have an average fiber diameter in the range 3 μm to 40 μm, and in which at least some of the fibers (108) are mutually aligned side-by-side over at least a portion of their length to form an upper fiber structure (206) having a larger diameter than the individual fibers (108) of the upper fiber structure (206) . |
