Simple dyes exhibit superior brilliance and dye uptake but commonly have decrease durability in terms of lightfastness and washfastness. Their steadiness might be improved by conversion into insoluble pigment sorts by means of reactions with tannins or heteropoly acids.

We have introduced in a few colors which have been similar to other companies, simple to use, with good shades, at far better costs. Now we have also introduced in some hues not Commonly available to the home dyer that happen to be a lot more Sophisticated in addition to a little bit much more complex to implement (Pre-metalized Acid Dyes), but supply better washfastness and lightfastness.
