QUE SIGNIFIE VAT DYE EN ANGLAIS
Colorant de vaisselle
Les colorants en cuve sont une classe de colorants qui sont classés comme tels en raison de la méthode par laquelle ils sont appliqués. La teinture de vat est un processus qui se réfère à la teinture qui se déroule dans un seau ou une cuve. Presque tout colorant, y compris les colorants réactifs aux fibres, les colorants directs et les colorants acides, peut être utilisé dans un colorant de cuve. Le coton, la laine et d'autres fibres peuvent être tous teints avec des colorants en cuve. Le colorant de cuve d'origine est l'indigo, une fois obtenu à partir de plantes mais maintenant produit synthétiquement.
