A revolutionary compound that works by releasing highly anionic products during washing-off.
Dyeing cotton can reach 100 liters of water/kilogram of fiber.
Dyeing cotton fibers with reactive dyes requires the process of washing-off of hydrolysed dye. This usually is a lengthy and difficult to achieve process, with heavy consumption of water, energy and time.
Generally, the most part of consumption occurs during the post-washing phase (rinse), necessary for extracting the hydrolysed dye that doesn't fix to the fiber during the dyeing phase.
THE H2AUX TECHNOLOGY
H2COLOR complexes with the hydrolyzed dye, removing it it in a more efficient way from the fiber during washing-off.
SAVES UP TO
H2COLOR is applied in conventional machines and can be integrated in production immediately.
State-of-the-art processes use an average of 8-10 washes for medium to dark colours, often at temperatures up to 100ºC, to remove the excess dye. By using H2COLOR, this number is reduced to 4-6 rinses at a maximum temperature of 60ºC.
Thus, only a short and low temperature washing-off is necessary, saving an estimate of 70% of the total water used, 60% of the total energy consumed and 50% of the total process time for medium to dark colours.
