Good Practice Information

Ecofoot is a spin-off founded in 2012, with the goal of bringing H2COLOR and other exclusive products to the market. The basis of the technology is to produce highly efficient ionic pigments for exhaustion dyeing, based on their unique affinity for natural fibres, and aimed at ecological processes and non-toxicological final products. None of the materials used contains any harmful substances
such as heavy metals, formaldehyde or halogens. Above all, the technology is considered to follow the main principles of ‘Green Chem’. H2COLOR particle dyes save energy by not needing hot washing-off after dyeing; they do not damage the environment when discharged into the effluent and can even be totally recovered in wet processes, such as those used in textile dyeing.

Evidence of success

Much less water is used since there is only one rinse. As pH is neutral, no sodium carbonate is used. Less time is used since 6-8 rinses are saved. The great advantage of H2COLOR is relative to dyeing cellulosic fibres is that the washing-off procedure at the end of dyeing is not needed; this saves more than 70% of water (95% if the water is reused), 70% of time and 60% of energy.
