Verfahren zur Herstellung eines Vliesstoffes, Vliesstoff und dessen Verwendung

摘要

The invention relates to a method for the production of non-woven fabrics, in which a lyotropic solution of cellulose carbamate in N-methylmorpholine-N-oxide (NMMNO) is spun into a plurality of filament yarns by means of extrusion through a nozzle beam containing a plurality of openings via an air gap into a regenerating bath, said filament yarns being intermingled subsequently by being subjected to a flow with gaseous medium and/or fluid. The invention likewise relates to non-woven fabrics of this type and the use thereof.
