Process for processing natural cellulose fibers, particularly cotton fibers, comprising the steps of deposition of the fibers on a continuously moving cloth in order to form a lap from 100 to 800 g/m<2>, impregnation with a treatment solution, treating, and rinsing by means of an aqueous liquid, characterized in that the rinsing is carring out by applying said liquid in the form of jets directed towards a face of the lap perpendicularly to its displacement direction, with an energy from 2 to 60 kwh per ton of treated product. The rinsing station (100) comprises at least a needle injector (105, 115) arranged transversally to the lap and which applies the high pressure water jets onto its surface. The liquid is sucked through a transverse slot communicating with a sucking box (110, 125).

Procédé de traitement de fibres cellulosiques naturelles, notamment de fibres de coton, comprenant les étapes de dépôt des fibres sur une toile en défilement continu pour former une nappe de 100 à 800 g/m2, d'imprégnation avec une solution de traitement, de traitement, puis de rinçage au moyen d'un liquide aqueux, caractérisé en ce que le rinçage est réalisé par application dudit liquide sous forme de jets dirigés vers une face de la nappe perpendiculairement à son sens de défilement avec une énergie de 2 à 60 kwh par tonne de produit traité. Le poste (100) de rinçage comprend au moins un injecteur-aiguilles (105, 115) disposé en travers de la nappe et qui applique des jets d'eau à pression élevée sur sa surface. Le liquide est aspiré au travers d'une fente transversale communiquant avec une caisse aspirante (110, 125).
