A nanotechnology based product for dyehouses that saves water, energy and time with the same machinery. 
 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.
Complexes with the reactive dye, avoiding hydrolysis to a great extent. In this way, there will be less hydrolyzed dye to remove in the washing-off process.
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.
