ColorZen® is a breakthrough technology that transforms the cotton dyeing process, making it significantly more efficient and environmentally friendly. Cotton is the most popular fabric on the planet, and once treated by ColorZen, it can be dyed using far less water, energy, dye, salt, and toxic chemicals, thus revolutionising the global cotton dyeing industry. ColorZen is on a scaling path to treat hundreds of millions of pounds of cotton and potentially billions of garments over the next few years.

Basically, the company has created a holistic and sustainable solution for cotton dyeing, one of the most inefficient and environmentally problematic links in the textile supply chain today. In doing so, the company has also given the industry a remarkable new innovation that allows for both beautiful new design, as well as rapid speed to market. Here we are giving an overview of this whole concept and how it’s going to be beneficial for the industry.

We all wear colored cotton

Until now, there has been no way to dye it without using enormous amounts of water, energy, and chemicals. The current process is not only inefficient but it has a deadly toxic output. In many cases, our precious environment is polluted by this process. Our rivers run hot pink and canary yellow with its poisonous effluent, killing aquatic and wildlife, while rendering fresh water unsafe to drink for millions of people. Change your clothes, change the world.

Cotton is the most popular fabric on the planet

By positively affecting its environmental footprint, we can make a huge difference, leading the fashion industry and its consumers into a new era of sustainability. We can grow cotton responsibly, but until now, we haven’t been able to dye it without using toxic chemicals. ColorZen technology allows your favourite brands to produce truly responsible, sustainable garments, for the first time. Raw cotton is grown, harvested, and ginned to remove impurities. The raw fibres are then spun into yarn. A mill knits or weaves the yarn into fabric, and that fabric enters the dyeing process.

How was cotton dyed before ColorZen?

The dye bath conventionally requires a large amount of water, dye, salt, and chemicals, in order to force a chemical reaction that binds the dye to the cotton fabric. Its treatment adjusts the molecular composition of cotton, allowing it to accept dye without the use of toxic chemicals. With ColorZen, cotton not only dyes cleaner, it can achieve bolder, brighter colours than ever before.

How does ColorZen do it?

The ColorZen dye bath requires just 10 per cent of the water conventionally used.

ColorZen dyes with no chemicals

Plus, a 50 per cent reduction in dyestuff, with 97 per cent dye retention means the water left over after a ColorZen dye cycle can be reused. Traditional cotton dyeing techniques require toxic chemicals, which are often dumped into fresh water sources, contaminating the ecosystem for aquatic life, and poisoning our drinking water. ColorZen dyeing is a closed-loop, non-toxic process, which means the water from the dye bath can be reused over and over again.

How is this possible?

ColorZen achieves 97 per cent dye exhaustion, leaving the dye bath water clean to recycle. ColorZen™ heather yarns are produced by blending a percentage of ColorZen™ cotton fibre with conventional cotton fibre. The ColorZen™ fibre absorbs the dye while the conventional fibre doesn’t. The fabric (or garment) can be dyed as one piece with one colour and a single dye cycle, which results in a multi-coloured heather fabric.

This will accelerate speed to market for heather and patterned garments. ColorZen™ fabrics can be stocked in an undyed form and dyed upon demand. Additionally, unlike conventional heathers, ColorZen™ heather fabrics can also be pre-bleached so bright heather colours or even pastel colours can be produced.

Sourcing it in India

In India, ColorZen is represented by its agent ‘Tangibles’, which is Coimbatore, Tamil Nadu based company. Tangibles is headed by Kumareswar, who has over 28 years of experience in the apparel industry.
