Concentrated Formaldehyde Free Cationic Dye Fixing Agent
Cristofix Supreme FDF improves the wet fastness of reactive dyeings and prints. It also improves the storage stability of reactive dyeings, which under humid conditions tend to undergo hydrolysis, adversely affecting the wet fastness properties.
Cristofix Supreme FDF acts by combining with the reactive dye hydrolysates that have not been washed off and would have otherwise reduced the fastness of the dyeings. The extent of improvement in the fastness properties depends on the specific dyes present.
Cristofix Supreme FDF does not significantly affect the shade of reactive dyeings nor does treatment with Cristofix Supreme affect the fabric handle. The rub fastness is not impaired as long as the dyeings are well soaped and rinsed.
