Highly substantive, anionic, direct dyes, specially developed for the paper industry
They are particularly suitable for dyeing wood-free paper and board in the stock and at the size press.
Advantages of Cartasol F dyes:
In some combinations of selected F and K-dyes (for example, tissue dyeings), the addition of a fixative is not necessary since the F dye is fixed by the K dye The usual Clariant recommendation when both K and F dyes are being used is to add K dye at an earlier addition point than F dyes as superior economics results. Colored two-sidedness can be reduced or eliminated. Cartasol F dyes are not sensitive to pH variations and can be applied in the range 4 to 9.
- High affinity, giving high color yield, clear backwaters and the possibility of adding the dyes late in the stock flow system
- The liquid dyes are particularly suitable for continuous addition
- Good bleedfastness
