Abstract

L'invention concerne une machine numérique de teinture à jet d'encre, la machine comportant un dispositif de dévidage et d'alimentation, un dispositif à jet d'encre, un dispositif de séchage et un dispositif d'enroulement qui sont disposés séquentiellement dans une direction d'alimentation en tissu, le dispositif à jet d'encre comportant un corps de machine, un moyen de commande, un réservoir d'encre, un réservoir de liquide de nettoyage, un bac à liquide résiduaire et un module à jet d'encre; le corps de machine étant muni d'au moins deux ensembles de modules à jet d'encre, d'au moins un réservoir d'encre, d'au moins un réservoir de liquide de nettoyage et d'au moins un bac à liquide résiduaire; le module à jet d'encre comportant une tête de pulvérisation, un cadre de positionnement, et un mécanisme de soutien et de déplacement; et une pluralité de têtes de pulvérisation disposés parallèlement formant un ensemble de ensemble de têtes de pulvérisation, et chaque module à jet d'encre contenant au moins un ensemble de têtes de pulvérisation. La solution utilise des têtes de pulvérisation fixes monocanal pour déposer régulièrement des points d'une encre assortie en couleur d'un seule couleur sur un textile de façon à accomplir une impression numérique en couleur pure. Ainsi, la machine de teinture à jet d'encre ne cause pas la perception la plus gênante de particules ponctuelles, telle qu'observée dans une machine conventionnelle d'impression numérique, est considérablement améliorée en ce qui concerne l'effet de coloration comparé à l'effet de coloration de l'impression d'une couleur pure par la machine d'impression, et présente les avantages du nettoyage et de la rapidité.
