Pigments are used in a wide variety of segments from the designs on your clothes to the colour of your shoes and bedsheets. But it is not complete yet, pigments are also used to color building material such as vinyl and brick cladding, plastic, medicine, cosmetic, the books and magazines we read, even the food we eat.

Dyes and pigments are the agents that are responsible for making our world so colorful today. In earlier times, dyes were sourced from plant and animal kingdom and even today some industries and applications still use such naturally sourced dyes. However, only a few of them have made it to the commercial markets.
A life without colors is just not imaginable! Color is at the very core of a vibrant and an inspiring life. From our attire to our houses to the food and even the packaging, color has become an integral aspect of our life. Providing a wide array of dyes and pigments that make our lives so colorful is a major task done by the manufacturers; acid dyes manufacturers, solvent dyes manufacturers, basic dyes manufacturers and many more are striving to bring out safe and stable colors.

Dyes and pigments are two types of colorants that play an important role in various applications. One of the greatest beneficiaries of these colorants has been the textile industry. Varied hued fabrics and prints to suit the mood and the occasion are being made available through these colorants. However, every variety of dyes and the pigments have their own characteristics that make them suitable for certain fabric types as against others.

Dyes and pigments have evolved tremendously over the years and today their importance is not limited to lending color to various substrates. They have also become a vital constituent of biomedicine and biotechnology industry. Their journey has been a long one beginning with research into devising varied colors and forms that would act as colorants to plastics, textiles, inks and printing, paints and every possible aspect of our daily lives.

The trend of today’s generation is towards focusing greatly on the health and wellness factors in their life. This applies to all aspects of their daily life including apparel and footwear. With respect to their clothing, they would prefer garments that remain fresh and odor-less for longer times. The textile industry capitalizing on this potential opportunity came out with a cutting edge technology that fulfills the desires of the millennial generation of today.

The world-wide colorant industry which comprises of pigments, dyestuffs and the intermediaries runs into billions of dollars. The textile sector is one of the major users of colorants and India is one of the leading suppliers of textile garments and furnishings world-wide. Therefore there is a greater emphasis by the marketing brands here to provide top quality products to the consumer. One way of doing this is to adhere to the quality norms laid down by the different stake holders like brands, consumers, regulatory authorities, colorant producers and textile processors.

Fashion is not only about designing costumes but also extends to fragrances and flavours. A garment with an aesthetic appeal can only be designed if there is a perfect combination of fabric with colour. The reactive dyes manufacturers, vat dyes manufacturers and those of acid dyes ensure a high quality product which gives strength, light fastness, washing fastness and rubbing fastness to the dye. Whereas the herbal extracts manufacturers extract products from natural sources which are used in fragrances and flavours. Their end use is in industries like cosmetics, food, perfumeries, Pharmaceuticals, etc.
Water is a scarce resource and should be used with minimum wastage both in household and industrial applications. Today, along with reducing the carbon imprint it has become utmost essential to sort out the water management problem. Scarcity of water and water pollution can derail your production process or the supply chain, lead to fights with other water users or damage corporate reputations.
Problems of large water consumption are closely related to the textile industry which has become a global industry in today’s times. Textiles adorn every single item of your daily life right from high fashion apparels and furnishings to the filters in your washing machines and vacuum cleaners. However, the same textiles leave maximum water footprints on Mother Earth and pose a big problem to the delicate ecological balance.
Polyester and cotton, two largest mass marketed textiles require large amounts of water in their dyeing process. Dye houses in the country not only consume huge quantities of water for the purpose and but also discharge large amounts of harmful effluents into rivers or the local streams. Using water friendly technologies or having efficient water management systems in place is one of the biggest challenges faced by the textile industry. It is essential for the industry to undertake major steps to mitigate the environmental harm that is being caused by the dyeing process which uses various dyes such as acid dyes manufacturers, reactive dyes manufacturers, vat dyes manufacturers, basic dyes etc.
Some steps in this regard have been undertaken by several manufacturers. One way is to reduce the dye-to-water ratio, however, the answer to this lies in the mechanisation of the factory’s manufacturing processes. Moreover, the natural fibres pose much of a problem for adopting waterless dyeing methods. Polyester can be coloured in airless environment where dyes are dispersed throughout the material under pressurized high heat. Wool and cotton however, undergo damage if they are passed through this environment.
Inspite of this, several companies have undertaken efforts in reducing water consumption to a great extent in dyeing natural fibres. One effort taken in this regard was changing the molecular structure of cotton such that it permitted the dispersion of dyes throughout the fabric using very less amounts of water. Energy as well as water consumption are said to have been drastically reduced with this technology.
Another technique used is to embed textile dyes within the fabric, all the while using air for the dye dispersion process. Yet another method that has found acceptance in the industry is use of pressurized and compressed carbon dioxide to disperse dye within the fabric. The carbon dioxide which is held in chambers of stainless steel assumes liquid-like properties. After the dyeing process is complete the carbon dioxide takes on its gaseous form and separates from the dye within the fibres. The dye within the fibres condenses and the carbon dioxide is recycled and used again for the dyeing process. However, this is simply said than done as the investment required for the technology is still huge.
Nevertheless, many large companies are aggressively finding ways and means to reduce or eliminate water consumption in their dyeing process and the day when all manufacturers use water-less or near-water-less technologies for dyeing will not be far off.
