The Dance of Colour (Dying of fabric.)

Colour is a catalyst for sales and success within the Textiles industry; it is the first thing that consumers observes the garments.
Before feeling the fabric, trying on for size, or considering the manufacturing processes, colour preference impacts the eye.
The development of natural dyes took place at the same time after the technique of weaving had been discovered in about 5000 BC. In India, the use of natural dyes for dyeing, painting and printing goes to the prehistoric periods. Ajanta paintings, dated as far back as 1st century AD, were painted with natural dyes.
India’s expertise in natural dyes dates back to ancient times, with even the Vedas referring to their properties. Weaving of and printing on fine textiles form part of a continuous tradition. 
India had a virtual monopoly in the production of dyed painted and printed textiles for a long time. The knowledge of which mordants (substances which are used to fix a dye to the fibre) to use and how to use them remained a closely guarded secret. From the 15th century onward, block printed textiles from Gujarat and Deccan adorned Europeans and their homes. Then, in the 19th century, the discovery of chemical dyes dealt a massive blow to the Indian textile industry.
Dyeing and printing are processes employed in the conversion of raw textile fibres into finished goods that add much to the appearance of textile fabrics.
Most forms of textile materials can be dyed at almost any stage. Quality woollen goods are frequently dyed in the form of loose fibre, but top dyeing or cheese dyeing is favoured in treating worsteds. Manufacturers prefer piece dyeing, which allows stocking of white goods, reducing the risk of being overstocked with cloth dyed in colours that have not been ordered.
At present, a higher demand is put towards the use of natural dyes due to increased awareness of the environmental and health hazards associated with the synthesis and use of synthetic dyes.
The quality of end products like fabrics depends on the quality of their components like yarns. Textile finishing processes are usually used to improve the quality of materials. Among these, mercerization is one of the most important wet finishing processes of cotton materials, as it improves handling and appearance of cotton fibers to simulate the superior properties of synthetic fibers. In addition, Mercerization treatment improves dye ability and luster required for appearance, smoothness and strength.
Textiles leave one of the largest water footprints on the planet and dyeing poses an especially big problem. Dye factories in India and China are notorious for not only exhausting local water supplies, but for dumping untreated wastewater into local streams and rivers.
The industry's challenge is to adopt more water-friendly technologies to dye cotton, silk and polyester, the three most mass marketed textiles. 
So what can companies do to mitigate the effects of this timeless, yet toxic, dyeing process?
The pollution of the environment has led to
Waterless dyeing is the process by which dyeing is perform without water. It is the process that used no water and requires less energy than traditional methods of dyeing, while still achieving impressive colors in solids and prints. Waterless dyeing process required less process, time, chemicals, & auxiliaries.
"Color! What a deep and mysterious language, the language of dreams."
