Reactive Dyes
Before going further let us first understand what is reactive dyes?
Reactive dyes are extremely coloured organic substances that are utilized for colouring textiles. The word ‘reactive’ itself refers to the chemical reaction that takes place when a reactive dye is applied to fibre. The particle of the dye formulates a covalent bond with the fibre – this is one of the toughest types of reactive dyes, and guarantees that the colouring is long-lasting. Unlike other dyestuffs that adhere to the material by absorption, fibre reactive dyes have a strong attachment and are hardly ever removed by washing.
The reactive dyes in textile constitute the most frequently used class of dyes for dyeing cellulosic textiles. Because of the decent versatile reactive dyes properties, such as ease of application, water solubility, variety of application techniques, availability of diverse shades, brightness of colour shades, good to excellent wash, light retreat and reasonable price.
Reactive dye usage is pretty popular in the textile printing industry and takes part in printing on nylon, cotton, wool, silk, blended, and many other fabrics. Properties of reactive dyes offer a cost-efficient, simple dyeing procedure and useful applications with an extensive range of colours and vibrant shades. The current applications of reactive dye include continuous and semi-continuous dyeing, exhaust dyeing, inkjet printing, direct printing, discharge printing, resist printing, and more.
To find the right Reactive dye and dyeing procedure for your business, we invite you to explore one of the best Reactive Dyes Manufacturers in India i.e. Megha International.

Reactive Dyes Manufacturing Process
The manufacturing process for reactive dyes involves the following steps:
The first step in the reactive dyes process is synthesizing the dye in a laboratory using various chemicals and reagents. The resulting product is then purified and tested to ensure its quality meets the required specifications.
The synthesized dye is then made into a liquid form, which is mixed with other chemicals to create a dye solution. The solution is then tested and adjusted to ensure its consistency and colourfastness properties are optimal.
Once the dye solution is ready, it is applied to the fabric through various dyeing techniques such as exhaust, pad batch, or continuous methods. The choice of dyeing technique depends on the fabric type, the desired colour, and other factors.
After dyeing, the fabric is washed and treated to remove excess dye and improve its colourfastness properties. The treatment involves rinsing the fabric in water, treating it with an alkali solution, and then washing it again.
After treatment, the fabric is dried and inspected to ensure that it meets the required quality standards. The inspection involves checking the colour, shade, and colourfastness properties of the fabric.
Finally, the fabric is packaged for shipment. The packaging process involves folding the fabric neatly, labelling it, and packing it in a manner that ensures it does not get damaged during transit.
Types of Reactive Dyes
Reactive dyes classification depends upon their properties and then they are used in different applications accordingly. Let us understand them in detail.
Cold Brand Reactive Dyes
The cold brand dyes are formulated with a reactive system based on “Dichloro Triazine.” These dyes are highly reactive and are usually applied at a temperature of around 40°C. They are suitable for dyeing cellulose materials using various dyeing methods, such as exhaust, pad batch, pad dry steam, and pad dry thermofix.

Hot Brand Reactive Dyes
Hot brand dyes are a type of dye that uses a “Monochloro Triazine” reactive system to bond with fibers during the dyeing process. They are applied at high temperatures, typically above 60°C, and are suitable for dyeing cellulosic materials such as cotton, rayon, and linen. The hot brand reactive dyes are known for their high colour fastness, brightness, and excellent wash-fastness. They are commonly used in the textile industry for dyeing fabrics and garments.

HE Dyes
These dyes mostly referred to as HE dyes are fit for cellulosic materials and dyeing cotton. Highly Exhausted Dyes possess considerably higher fixation and exhaustion efficiency, which results in high reduction in cost, when compared to conventional reactive dyes. Good build up and high fixation is of precise importance when dyeing cellulosic blends/polyester. The exhaustion of these dyes can be controlled with particular temperature and salt addition in order to give level dyeing, before Alkali is added.

Vinyl Sulfone Dyes
Vinyl Sulphone Brand Dyes utilize a reactive system based on “Vinyl Sulphone Ester.” These dyes are suitable for dyeing cotton and other cellulose-based materials using exhaust, batch wise, continuous, and thermolixation processes. Vinyl Sulfone Dyes are suitable for printing using one or two-phase application methods. The dyes have an excellent white effect on dyed grounds and can be used with discharge and resist printing methods. Moreover, they have easy wash-off properties and do not stain as the hydrolyzed dye does not have an affinity for the substrate.

To know more in details about the classification of Reactive Dyes
Reactive Dyes Properties
- Reactive dyes are anionic dyes that are used for dyeing cellulose, protein and polyamide fibres.
- During dyeing the reactive group of this dye forms covalent bond with fibre polymer and becomes an essential part of the fibre.
- Reactive dyes are soluble in water and are found in liquid, power and print paste form.
- Textile materials dyed with reactive dyes have a decent wash fastness with rating about 4-5 due to robust covalent bonds formed between fibre polymer and reactive group of dye.
- Reactive dyes have an extremely good light fastness with rating about 6. The dyes have very stable electron prearrangement and can protect the degrading effect of ultraviolet rays.
- Reactive dye gives brighter shades and has reasonable rubbing fastness.
- Dyeing method of reactive dyes is simple and easy. It needs less time and low temperature for dyeing.
- Reactive dyes are comparatively cheap and have good perspiration fastness with rating 4-5.
Advantages of Reactive Dyes
- Due to its ability to react with the medium gives a massive advantage to reactive dyes as they become much more long-lasting as well as visually different. This feature gives it a strong benefit over prohibited colours as well as cellulose colours.
- Reactive Dyes have another solid advantage that is its wet speed, attained through an effective and straightforward colouring procedure.
- The fibres that are dyed with reactive dyes can be safely dyed even with white garments without the risk of colouring it.
- Reactive dyes are appropriate for dyeing a new type of cellulose fibre products like Lyocellfibres.
Reactive Dyes Uses
Reactive dyes are primarily used for dyeing cellulose fibres such as viscose and cotton, but they are also progressively gaining significance for wool and polyamide. The wide range of available reactive dyes is extensive and allows a large number of dyeing techniques to be used.
Some of the common reactive dyes examples include:
Textile Colouring
Reactive dyes for cotton and other natural fibers are widely utilized in the textile industry for their colouring properties on fabrics such as cotton, wool, silk, and others. They are also used to dye synthetic fibers such as polyester, nylon, and acrylic.
Printing
Reactive dyes can be used to print designs on fabrics using different printing techniques such as screen printing, roller printing, and inkjet printing.
Paper Colouring
Reactive dyes are also used to colour paper and paper products. They are used in the production of paper for books, magazines, and other printed materials.
Leather Colouring
Reactive dyes are used to colour leather and leather products such as shoes, bags, and belts.
Food Colouring
Some reactive dyes are also used as food colouring agents, although their use in food is highly regulated and limited.
Overall, reactive dyes are versatile and widely used in various industries for their excellent colour fastness and durability.
