CARTASOL K Dyes: Cationic direct dyes with superior performance
Although cationic in nature these dyes offer vastly superior properties to traditional basic dyes. They are structurally closer to Cartasol F anionic direct dyes and are applicable in the same industry segments, namely fine paper, board and particularly tissue.
Due to their cationic charge they have excellent substantivity and affinity for the fiber and have a very rapid exhaustion, meaning they only require a short contact time to achieve full dye yields with clean backwaters. Due to this short contact time required the Cartasol K dyes can be added very late in the system, which allows for rapid colour correction and cleaner stock systems and thus shorter shade changeover times. An added benefit is that Cartasol K dyes do not require any fixative, saving on costs and complexity.
