Dyeing with H2COLOR-Denim is a simple short process that does not need reduction nor oxidation. The indigo pigment is in the form of a liquid dispersion of Indigo pigment complexed with H2COLOR-AUX
particles. The dispersion is stable and homogeneous, something that cannot be achieved using indigo alone. It is then ready to be applied by an exhaustion process, using a proprietary fixing agent. It is a simpler process and level colors are obtained on fabric or garment dyeing.
Dyeing is performed at 60ºC for 1 hour at neutral or weakly basic conditions, followed by 2 rinses of 10 minutes each, at a liquor ratio of 1:10, at room temperature, and then proceed to washing to wash-down the excess indigo.
Process for a mild washing effect is in washing machine with the abrasion caused by the tumbler of the machine itself.
