An acid dye is a dye that is typically applied to a textile at low pH. They are mainly used to dye wool, not cotton fabrics. [1] Some acid dyes are used as food colorants, [2] [3] and some can also be used to stain organelles in the medical field. Acid dyes are anionic, soluble in water and are essentially applied from acidic bath.

Fiber-reactives dyes are relatively safe and simple to use, [3] and are the same dyes used commercially to color cellulosic fabrics. Protein-based fibers such as silk, wool, and feathers, as well as the synthetic polyamide fiber nylon, can be dyed with acid dyes. Acid dyes are effective at acidic (low) pH, where they form ionic bonds with
Although almost all dyeing can be done in a vat, the term vat dye is used to describe a chemical class of dyes that are applied to cellulosic fibre (i.e., cotton) using a redox reaction as described below. Because of the use of caustic soda, and the very high pH of the dye bath in the dyeing process, wool cannot be dyed using vat dyestuffs.
Natural dyes are dyes or colorants derived from plants, invertebrates, or minerals. The majority of natural dyes are vegetable dyes from plant sources—roots, berries, bark, leaves, and wood—and other biological sources such as fungi. [1] Archaeologists have found evidence of textile dyeing dating back to the Neolithic period.
This range contains a mixture of 3 different dyes - direct, acid and disperse. Direct dyes are for cellulose based fabrics, acid dyes for wool and nylon and disperse for some plastics. None of these are reactive dyes and are less wash fast than the other ranges. It comes in 26 colours. [3]
