The H2COLOR-AUX is made up of polymer particles.
The H2COLOR-AUX has affinity for the dyestuff and attaches itself to the hydrolysed reactive dye.
The particles are designed in a way as to be dissolved at temperature higher than 50℃ and at high pH (alkaline environment) a process that starts during the first wash-off stage. The polymer decomposes and releases highly anionic products, leading to formation of a layer between the dye and the fibre.
This layer repels the hydrolysed dye and promotes a simple and effective removal right from the first wash-off stage of hydrolysed dye.
