À quoi servent les Fixateurs de colorants ?
Après teinture en tambour ou par pulvérisation, la teinture non fixée peut migrer pendant le graissage et la finition — provoquant une variation de teinte et une mauvaise solidité. Les fixateurs de colorants forment des associations avec les molécules de teinture et les sites fibreux, verrouillant la couleur avant… Venus Ethoxyethers fabrique et fournit en Inde ; demandez un devis pour vos besoins.

Rôle dans la teinture du cuir
Après teinture en tambour ou par pulvérisation, la teinture non fixée peut migrer pendant le graissage et la finition — provoquant une variation de teinte et une mauvaise solidité. Les fixateurs de colorants forment des associations avec les molécules de teinture et les sites fibreux, verrouillant la couleur avant les processus humides ultérieurs et l'application du vernis de surface.
Intégration au processus
Les fixateurs de colorants sont utilisés aux côtés des syntans liquides, syntans en poudre et graisses dans la gamme de produits chimiques pour cuir Venus. Le prétraitement en tannerie avec les produits de tannerie assure une absorption uniforme de la teinture dès le départ.
