Ecofoot has also developed Hybrid Pigments, based on a dye chemically linked to a polymer 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 are present and no ammonia is used.
For printing H2COLOR pigments behave like reactive dyes, since there is a reaction involved. It can be applied as a pigment with a thickening agent and a binder, not needing a fixing agent for improving fastness, since it reacts with cellulosic fibres. Digital printing formulation works in the same way, the pigments being applied to cellulosic fibres on a fabric pretreated with a propietary binder, not needing a fixing agent for fastness improvement.
