Naphthol Padding
The fabric is first impregnated with a Naphthol solution (Fast Colour Salt) prepared using caustic soda. This step ensures the dye precursor is thoroughly absorbed into the fibers.
Diazo Development
The treated fabric is then passed through a diazo solution (Fast Base), initiating the dye formation process.
Coupling Reaction
A chemical reaction occurs between the Naphthol and diazo components directly on the fiber, forming an insoluble azo dye within the fabric pores.
After-Treatment
The dyed fabric undergoes soaping and washing to enhance brightness and improve fastness, resulting in vivid and durable coloration.
