Acid
dyes are the dyes that are water soluble anionic dyes
and are
applied to fibres such as silk, wool, nylon and
modified acrylic fibres from neutral to acid dye
baths. Acid dyes are not substantive to
cellulosic fibres. Acid dyes require the use of
an acid such as vinegar, acetic or sulphuric
acid to set the color. |

Acid dyes sound scary to some novices. In fact,
the dyes are non-caustic, are in many cases non-toxic, and are named for the mild acid (such
as vinegar) used in the dyeing process, and for
the types of bonds they form to the fiber. Some
of them are significantly more toxic than fiber
reactive dyes, while others are even safe enough
to eat, and are sold as food coloring.
Acid dyes fall into several categories:
1. leveling acid or strong acid dye
2. milling or weak acid dyes
3. super milling or fast acid or neutral acid
dyes.
