REGENERATED CELLULOSE FIBRE

Regenerated cellulose fiber in the form of a solid viscose flat fiber, is claimed. The fiber is made of more than 98% cellulose. The ratio of the width to the thickness of fiber is >= 10:1. The fiber surface is substantially smooth and the fiber is transparent. Independent claims are also include...

Beschreibung
Zusammenfassung:	Regenerated cellulose fiber in the form of a solid viscose flat fiber, is claimed. The fiber is made of more than 98% cellulose. The ratio of the width to the thickness of fiber is >= 10:1. The fiber surface is substantially smooth and the fiber is transparent. Independent claims are also included for: (1) fiber bundle comprising a number of cellulose fibers; (2) producing the cellulose fiber or the fiber bundle, comprising providing a viscose spinning mass, spinning the viscose spinning mass through at least one slot-shaped orifice of a spinneret in a spinning bath to form filaments, where the viscose spinning mass contains a coagulation retardant, preferably polyethylene glycol, where the ratio of length to width of the nozzle slot is 10:1-30:1, preferably 15:1-25:1, and a content of sulfuric acid in the spinning bath is 110-140 g/l, preferably 120-130 g/l, removing the spun filaments with a nozzle lag of 2-3, and stretching the spun filaments after leaving the spinning bath in a proportion of 20-35%, preferably 25-35%; and (3) a paper comprising cellulose fiber and fiber bundle.
