Virtues and Shortcomings of Reactive Dyes in Textile Industries

Posted by Bharat Patel on April 16th, 2018

Dyeing is a process of transforming a simple looking substrate into a luxurious one. Most brands have used and are using reactive dyes for pushing their brand name further. Dyeing is not just a colouring process instead they add value to the product. New dyeing technologies challenge the existing ones and try to frame a new experience. This keeps the manufacturers on their toes to deliver ultra-rich looks for the customers. Manufacturers like Sudeep Industries are known to extract the best by troubleshooting underlying quality problems.

Reactive dyes are known to be the best choice amid manufacturers to exclusively strengthen their presence in growing market. Like other dyes reactive dyes too have a bitter side that is likely to be not-liked. Here are some favorable and no-so-favorable aspects of reactive dyes.

Positives:

Most permanent of all dye types:

Reactive dyes have made their presence because of their permanency when linked with fibres. This is because of the covalent bonds they form with substrate molecules. Covalent bonds are known to be the strongest among all which is reflected in reactive dyeing process. Hence offering colour stability.

Wash resistant:

Although reactive dyes fall under synthetic dyes that are water soluble but they become water resistant after manufacturing. You can easily wash white clothes with them without any fear of colour transfer.

Better colour resolution:

As reactive dyes are water soluble they reach every bit of the substrate giving it opulent looks. They blend with the substrate completely giving it a rich uniform appearance.

Economical prices:

Even after being rich with the looks and quality they do not cost high. As they are affordable, manufacturers Visit reactive dyeing technique for high-class production.

Negatives:

Lack of light fastness:

Although reactive dyes have strong intermolecular bonds but they could not stand tough lights. Drying reactive dyed substrates under direct sunlight can harm their colour texture. They will lose their shade faster if dried under heavy lights.

Short life:

Reactive dyes have long life but they lose their stability under heavy UV light. Over exposure can degrade their quality and hamper the lifespan.
