Abstract

L'invention concerne un appareil pour fabriquer des fibres de cellulose dans un processus de filage au mouillé et un procédé de fabrication de fibres de cellulose. Pour fournir un procédé de fabrication de cellulose qui peut être utilisé à grande échelle industrielle et un appareil associé, un appareil comprenant les éléments suivants est envisagé : - un appareil de malaxage et d'évaporation qui est conçu pour recevoir une suspension de filage à base de cellulose et un liquide ionique et pour faire tourner la suspension de filage dans une solution de filage, - une unité de filage pour fabriquer des fibres de cellulose préliminaires continues, - un bain de coagulation pour précipiter des fibres de cellulose continues à partir des fibres de cellulose préliminaires, - une unité d'étirage pour appliquer une tension préliminaire aux fibres de cellulose provenant du bain de coagulation, - un bain d'étirage pour étirer et pré-laver les fibres de cellulose provenant de l'unité d'étirage, - une unité de lavage avec au moins un bain de lavage pour laver les fibres de cellulose après étirage, - au moins une unité de séchage pour sécher les fibres de cellulose lavées, et - une unité d'enroulement pour enrouler les fibres de cellulose séchées.
