The approach in which the fabric is first treated with a remedy of the coupling element and then placed in a resolution of the diazonium salt to kind the dye on the fabric was patented in 1880. Alternatively, the fabric can be treated with a remedy of the diazo element ahead of diazotization, followed by immersion in a option of the coupling component this method was patented in 1887. After drying, the fabric is untied to reveal irregular circles, dots, and stripes. Varicoloured patterns could be made by repeated tying and dipping in extra colours. This hand method, common in India and Indonesia, has been adapted to machines.
