Ecofoot has also developed Hybrid Pigments, based on a dye chemically linked to a reactive particle, appropriate for Garment Dyeing of cotton garments at low temperatures (25ºC) and no salt.
Garment Dyeing of Denim is traditionally done with Indigo, a very polluting process. Ecofoot-Indigo is a specific H2COLOR-Pigment, that is applied in Denim and tops (fabric or knitwear) in an ecological process, that avoids reducing agents.Oher colours of H2COLOR-Pigments are applied in the same way as indigo.
H2COLOR-Pigments can also be applied to wool, in a more ecological process than than the standar wool dyeing. No heavy metals aare present and no ammonia is used.
For printing H2COLOR pigments behave like reactive dyes, since there is a reaction involved. The washing-off is easier than for standard reactive dyes, saving in water and in energy. It does not need boliing to remove hydrolysed dye. It is specially recommended for knitwear, where washing.off in jet machines is specially inefficient.
