A method of manufacture of a nonwoven cellulose fabric involves the fibres being formed by extruding a solution of cellulose through at least one spinning jet and subjecting the extrudate fibre to a high velocity gas flow. The fibre passes through a vapour mist which at least partially coagulates the fibre prior to collection as a fibre web. By use of such method, a fabric having a high loft and a relatively low density may be obtained.

Procédé servant à fabriquer un non-tissé à base de cellulose et consistant à produire des fibres par extrusion d'une solution de cellulose à travers au moins une filière de filage et à soumettre les fibres extrudées à un écoulement de gaz très rapide. La fibre traverse une brume de vapeur qui la coagule au moins partiellement avant d'être recueillie sous forme de voile. Ce procédé permet d'obtenir un non-tissé possédant un gonflant important et une densité relativement basse.
