Fiber bundle comprises many regenerated cellulose fibers having many sides, whose cross section having at least three sides, where at least 10%, preferably at least 50% of the cellulose fibers having many sides are asymmetric fibers, in which at least one of the side with respect to its length differs from the other sides, where the length of at least one side is greater by a factor of 2-10 than the length of the side or shortest side. An independent claim is also included for producing the fiber bundle comprising (i) providing a viscose spinning mass, and (ii) spinning the viscose spinning mass through multiple orifices of a spinneret in a spinning bath to form spinning threads, where all the openings of the spinneret comprises at least three sides, in which at least 10% of the openings are asymmetrical openings. |
