ThenThe invention relates to a method for producing thermally stablenMolding or spinning solutions,nthe cellulose, an aqueous onenstable tertiarynAmine oxide, preferably N-methylmorpholine N-oxide (NMMO), a non-solventnfor cellulose,nin particular water, stabilizers and optionally differentnAdditives for modifying the properties and the afternthe dry-wet extrusion process into cellulosic fibers spunnor warped to films. It is characterizednone or more stabilizers in amounts of at least 0.01nMass%, based on the spinning solution,nare included, the polymer bound groups for metal ion binding and / ornfor aldehyde binding in a sufficiently basic spinning solution. |
