Abstract:
(DE) Die Erfindung betrifft ein Verfahren zur Herstellung von Vliesstoffen, bei dem eine Lösung von Cellulosecarbamat in N-Methylmorpholin-N-Oxid durch die Löcher eines Düsenbalkens gedrückt wird und durch einen Luftstrom um ein Vielfaches verstreckt wird. Der gebildete Faservorhang wird auf einem perforierten Transportband abgelegt, gewaschen und getrocknet. Ebenso betrifft die Erfindung derartige Vliesstoffe sowie deren Verwendung.
(EN) The invention relates to a method for producing bonded fabrics during which a solution of cellulose carbamate in N-methylmorpholine-N-oxide is forced through the holes of a nozzle beam and is stretched by a multiple by an air flow. The fiber curtain formed is placed onto a perforated conveyor belt, washed and then dried. The invention also relates to bonded fabrics of the aforementioned type and to the use thereof.
(FR) L'invention concerne un procédé de production de non-tissés, selon lequel une solution de carbamate de cellulose dans du N-oxyde de N-méthylmorpholine est pressée à travers les trous d'une rampe à buses et est considérablement étirée au moyen d'un écoulement d'air. La nappe de fibres ainsi formée est déposée sur une bande de transport perforée, est lavée et est séchée. L'invention concerne également de tels non-tissés, ainsi que leur utilisation.
