Pixabay Because of the textile industry, we have clothes on our back, linens and towels in our households, and a source of livelihood for many. While it provides one of the most basic commodity, the textile industry can also have a grave impact on the environment. Next to agriculture, textile industry is the second polluter of clean water. More so, there are 72 toxic chemicals that can reach water bodies through textile dyeing.
Share via Email Textiles have one of the largest water footprints. Dyeing is a big problem both in terms of water use and pollution.
Martin Godwin Textiles leave one of the largest water footprints on the planet and dyeing poses an especially big problem. Dye houses in India and China are notorious for not only exhausting local water supplies, but for dumping untreated wastewater into local streams and rivers.
So what can companies do to mitigate the effects of this timeless, yet toxic, dyeing process? A 1-to ratio is common. Diluting a dye, she countered, simply means wasting more water: Various fabrics require different manufacturing processes, so one best technology does not exist for low-water or waterless dyeing.
Colouring fabric using this waterless method could be feasible for polyester; natural fibres such as cotton and wool, however, can become damaged undergoing a similar process.
Another US firm, AirDye, insists its technology uses a sliver of the water and energy compared to traditional dyeing processes, and has several niche designers and manufacturers as customers.
Other than nebulous talk about partnering with NGOs to reduce water consumption, few large companies currently consider new waterless or near-waterless technologies. One that does is Adidas. The CO2, which takes on liquid-like properties, is contained in stainless steel chambers. After the dyeing cycle the CO2 becomes gasified, and dye within the cotton fibres condenses as it separates from the gas.
The CO2 is then recycled and pumped back into the dyeing vessel. Adidas claims using CO2 is a safe and environmentally-friendly option because the gas is contained and can be used repeatedly without the risk of any emissions.
Although dyeing using compressed CO2 has existed for over 25 years, Adidas claims a supplier in Thailand operates the only factory with the ability to scale this technology. So can this process transform the textile industry?
Not quite yet according to Christian Schumacher, an expert in textile dyes and chemicals, who points out that investment in such equipment is still costly. Nevertheless, assumptions water is integral to dyeing are crumbling. We discovered an answer that not only solved the intended goal, eliminating water, but also had multiple positive side effects, including a reduction in energy and chemicals.
And among large global brands and retailers, few have aggressively ventured into waterless dyeing technology. The answer in part lies in TirupurIndia, home to scores of factories and workshops where workers dye materials for t-shirts and other garments marketed around the world.
Local dye houses have long dumped wastewater into the local river, rendering groundwater undrinkable and local farmland ruined.Aug 25, · Green process cuts water use, pollution in textile industry.

The textile industry, which has been using copious amounts of water to dye garments for hundreds of years, may be reluctant to embrace this change.
After all, this new technology is expensive to install and only works on certain fabrics. The textile industry contributes to water pollution, but there are ways to lessen its environmental footprints. Here are four ways businesses can do so. Water Pollution.
