A new mordant, interesting for dyeing cellulosic fibers, in replacement of aluminum acetate.
This aluminum lactate is produced from lactic acid obtained by fermentation of renewable materials.
Natural dyeing – mordant recommended for cellulosic fibers : This mordant is used in the same way and in the same proportions as aluminum acetate for the natural dyeing of cellulosic fibers. Its solubilization is complete at room temperature. The colors obtained are intense.
As a preliminary step, we also recommend a first bath of a low coloured tannin (oak gallnut, sumach gallnut or tara) or with a tannin that will bring a light background color (acacia, myrobalan, chestnut).
