As brilliant as a peacock’s plume or as subtle as a twilight sky, the colours we see in our everyday life owe their vibrancy to an unsung hero: Vat Dyes. This blog will take you on a fascinating journey through the world of Vat Dyes, VAT Pastes, their manufacturers, applications, and much more. We will focus particularly on Vat Green 1, a popular choice among Vat Dyes Manufacturers.

Pigments and dyes are both coloring materials but each of them have distinct characteristics and lend colors to the substrate differently. Dyes can be used as a solution as they hold on to the substrate whether it is textiles, wood, hair or food. Pigments are items that are insoluble and need to be blended in binders so that they hold on to the substrate.
Colours and their various shades form an important aspect of domestic, commercial and industrial world. It is colours that enhance the aesthetic appeal of clothes, homes, food, offices, automobiles, cosmetics, waxes, paints, etc. They can also be used to offer a safety feature. There is great diversity in the demands of the market for colours depending on the area of application.

Colorants have become an integral part of everyday life and we cannot do without them for fulfilling even the basic necessities of our lives. Food, clothing and shelter which form the three pillars of basic life requirements have an element of colour in some form or the other in them.

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.
