Types of Dye Used in Textile Industry

Color gives life. Whenever it is added to something faded or use to cover what could be considered insipid and ordinary, the first thing one would like to do to make it appealing, is to incorporate color into the lifeless form.

There are also different color hues, as there are different color combinations. If you are just looking for the right color to complement your day, you will find that the possibilities are endless.

You might be wondering then how do manufacturers come up with these colored-textiles that are used in making your favorite shirt or that faded jeans that you see often worn by a number of kids hanging on the burger shop across the street.

Different colors are actually incorporated in the yarn or fabric that are sewn together according to the design specified by the wearer. To incorporate these colors, fabrics and yarns go through a process where the fibers are colored with either natural or synthetic dyes.

What is dyeing?

Dyeing is a primeval art which existed before written records. Sources reveal that it was performed during the Bronze period in Europe. Primeval dyeing techniques undergo tedious tasks of sticking plants to fabric or wiping crushed pigments into cloth. Through time, the process became more sophisticated. Later, we see natural dyes from crushed fruits, berries as well as other plants. These were boiled into the fabric and gave light and also water fastness (resistance) to the thread fiber. Dyeing can be completed “at any phase of the manufacturing of textile- fiber, yarn, fabric or a finished textile product including garments and apparels.” Color fastness, the property that is produced in the fabric or yarn in the process of dyeing, is determined by two factors- the selection of appropriate dye according to the textile material on which the dye will be applied, as well as the selection of dyeing method.

Dyes and its Different Types

Dyes are incorporated into the fiber of the yarn or the fabric through chemical reaction, absorption, or diffusion. In addition to this, dyes differ in their resistance to a number of agents, including heat, perspiration, washing, gas, alkalies, and so on. It is also dependent on their resemblance to different fibers, their reaction to cleaning agents and processes employed; as well as their solubility and in the method of application.

Finally, there is what we call synthetic as well as natural dyes. Synthetic dies are man-made dyes and are classified according to their chemical composition as well as the method of their application in the dyeing process. Natural dyes, on the other hand, are categorized into three types: natural dyes that come from plants and are called Indigo; those that come from animals are called cochineal, and those that were gained from minerals are called Ocher.

Gerald Booth via Wiki classifies dyes “according to their solubility and chemical properties,” and list them as follows: acid dyes, basic dyes, direct dyes, mordant dyes, vat dyes, reactive dyes, disperse dyes, azoic dyes, and sulphur dyes.
