Today, synthetic dyes have turned into an industry of very high dimensions. It is widely used for dyeing and printing in a wide variety of industries. There are over ten thousand dyes and they are produced in very large quantities.
The first man-made (synthetic) organic dye was found by accident in the 1850s, and thousands of synthetic dyes have been produced since then. Synthetic dyes quickly replaced traditional natural dyes. It costs less, is available in a wide variety of new colors, and gives painted materials better properties. Dyes are now classified according to how they are used in the dyeing process.
Almost all colors today are synthetic dyes. Synthetic dyes are used everywhere, from clothing to paper and from food to wood. These synthetic dyes, which are cheaper to produce, brighter, faster in color and easier to apply to fabric, find wide use in various industries. Scientists are formulating amazing new colors and natural dyes are no longer used in most applications.
Synthetic dyes are named according to the chemical structures of their special chromophoric groups. For example, diphenylmethane derivatives, triphenylmethane compounds, oxazine compounds and Azo dyes are one of the most popular varieties of synthetic dyes. Today, it is used up to 90 percent in dyeing units because it is versatile and easy to synthesize. With a few exceptions, most synthetic dyes are aromatic organic compounds that can be divided into groups such as nonionic (oil soluble), cationic, and anionic.
The main types of synthetic dyes are: acid dyes, azoic dyes, basic dyes, chrome dyes, enhanced (or diazo) dyes, direct dyes, disperse (or acetate) dyes, reactive (or fiber-reactive) dyes and sulfur dyes.
The main parameters used in the selection of synthetic dyes are: boiling, perspiration, fading, machine washing ability, gas fume fading, fastness evaluations, dry cleaning, hot pressing, steam pressing and salt water.
While synthetic dyes were used only in the textile industry, today these dyes serve many sectors such as medicine, chemistry, plastic, paint, printing ink, rubber, cosmetics and many other industries.
