There are a number of options available in the process of dying fabrics and different kinds of dyes are used in the various processes. However one of the most effective and widely used dying processes is the one that is done using naphthols. The process of dyeing using naphthol is done in combination with insoluble azo dyestuffs. There is a complete cycle of steps that need to be followed in the dying process to be able to get the right results. The use of the naphthol dyes is most common for cotton fabrics apart from other cellulosic fibres such as jute, hemp, linen and even silk and rayon. The method and practice of dying using naphthols is most widely seen in African and wax prints. Understanding the process of dying using the combination of naphthols and azo dyes can help in establishing where the application is most suited.

Acid dyes are highly soluble in water and have good light fastness compared to simple basic dyes. The acid dyes are most effective for the protein fibers like silk, wool, modified acrylics, and Nylon. They have sulphonic acid groups that are normally present as the sodium sulphonate salts. It increases the solubility in water and gives the dye molecules a negative charge. So as a group, acid dyes are divided into two subgroups – acid leveling or acid milling.
