Dyeing
process.
Materials.- All materials come from Switzerland. All coloring
materials have the OEKO-TEX Standard 100 ecological certification.
Biodegradable colors.
Additional materials.- conventional water, salt with 90% of absorption and
acetic acid aproximately 1.5%.
Residues elimination.- 0%. Water with neutral PH, without
acidification.
Residues elimination process.- The vapors of water is treated by using cotton
filters following Austrian evironmental regulations. After that, water is
treated by using three filter tanks. The first one, uses cotton again to filter
the water. In this tank the water is heavy. In the sencond tank, we add an
acid named "acido formico". The mixture of acids (formico and
acetic) makes several particles wich go to the deepest of the tank. From
here, just water goes to the third tank. This water in the third tank is soft
water and it is recycled to be used is other dyeing process (specially for
dark colors).
