Archroma and Jeanologia Launch Eco-conscious Denim Cleaning

Archroma, a global leader in specialty chemicals towards sustainable solutions, and Jeanologia, a world leader in sustainable and efficient technology development, joined forces to launch an eco-advanced alternative to the denim fabric washing process, including in some cases the mercerization, one of the most water-intensive and pollutant processes of denim fabric finishing.

It all starts with the spinning step where the cotton is turned into yarn. The second step is a pretreatment that will prepare the yarn for the dyeing step. The dyed yarn then goes through the sizing process, which is a treatment preparing it for weaving. At this stage, we have obtained a denim fabric that will go through a few more steps. First, the fabric may undergo a washing treatment or, in some cases, mercerizing treatment which consists of treating it with caustic soda in order to obtain a more lustrous, flat and less reddish blue and black denim.

First, the fabric may undergo a washing treatment or, in some cases, mercerizing treatment which consists of treating it with caustic soda in order to obtain a more lustrous, flat and less reddish blue and black denim.

In both traditional ways to clean the fabric, washing or mercerizing, multiple highly water intensive washings are required in order to restore optimal fabric pH and remove unfixed dyestuff and any undesired deposits or impurities from the fabric. One of such impurities released in the washing process is aniline, a substance that is classified as a category 2 carcinogen and considered toxic to aquatic life.

That is why Archroma and Jeanologia decided to team up and develop an alternative to the traditional fabric cleaning process and its subsequent water-intensive and water-polluting washings.

  • The breakthrough alternative to the fabric cleaning concept presented by Jeanologia and Archroma combines the use of the aniline-free* PURE INDIGO ICON dyeing system of Archroma, and the water-free** and chemical-free “G2 Dynamic“ finishing technology of Jeanologia.
  • The Archroma/Jeanologia solution allows to create aniline-free* denim, and improve the final aspect of the fabric through a fully chemical-free and almost water-free** cleaning alternative treatment.
  • The Archroma/Jeanologia solution can also be used with additional Archroma coloration systems such as INDIGO REFLECTION or PURE UNDERTONES.

Umberto Devita, Business Development Manager at Archroma’s Competence Center for Denim & Casual Wear, who was the project leader for this new development, comments: “At Archroma, we strive to develop solutions in line with our principles of “The Archroma Way to a Sustainable World: Safe, efficient, enhanced, it’s our nature”. It was therefore very inspiring to work with a partner who shares the same values of developing efficient new processes to bring all know-how to our customers to maximize value – for denim that looks as good as the good it creates.”

For Jean-Pierre Inchauspe, Business Director of G2 Dynamic at Jeanologia, “this association is another step to change traditional, more polluting and water consuming processes in the textile industry for new ones using technology, improving, and boosting subsequent production stages up to the finishing of the garment, making them more efficient and allowing companies to be more competitive, increase productivity and offer a product that is completely sustainable with high quality.”

Archroma celebrates 3 years of working with aniline-free Indigo Heroes

  • 18+ metric tons of aniline are estimated to have been removed from the denim supply chain in about 3 years(2).
  • That represents 300'000'000+ pairs of jeans free of aniline, with 18'000+ garment workers, and aquatic life, protected from its toxicity(2).

Archroma celebrates nearly 3 years of successfully converting the denim industry to aniline-free(1) pre-reduced liquid indigo.

Archroma launched its aniline-free(1) Denisol® Pure Indigo in May 2018(3).

Archroma launched its aniline-free(1) Denisol® Pure Indigo in May 2018(3).

Aniline is a key ingredient to make the indigo molecule. Unfortunately, during this process some aniline impurities are carried through into the indigo dyestuff. When the indigo is dyed on the fabric, a lot of the aniline impurity is locked into the pigment in the fabric. The remainder of the aniline impurity, approximately 300 metric tons annually, is discharged during dyeing. This can be an issue as aniline is toxic to aquatic life. In addition, exposure levels to factory workers can be high. The new Denisol® Pure Indigo 30 liq was therefore developed as an aniline-free(1) indigo solution for designers, manufacturers and brand owners who long for authentic indigo inspiration.

Since the launch of Denisol® Pure Indigo, several denim manufacturers, such as front-runner Absolute Denim, as well as Advance Denim, Azgard 9, Kilim Group, Nuevo Mundo, Rantex, Shasha Denim and Tuong Long, have taken the matter in their hands and converted their production or dedicated lines to aniline-free denim to brands and retailers.

The innovation is also supported by denim partners such as Be Disobedient and The Denim Window.

Archroma evaluates that, based on the total quantity of Denisol® Pure Indigo sold until its introduction, its partners helped remove almost 18 metric tons of aniline from the denim supply chain. That represents an equivalent to about 300’000’000 pairs of jeans free of aniline and more than 18’000 garment workers protected from its toxicity(2).

Absolute Denim to become first denim manufacturer to convert 100% of its production to ground-breaking Aniline-free* indigo solution by Archroma

Archroma, a global leader in color and specialty chemicals towards sustainable solutions, today announced that Thailand-based Absolute Denim will be the first denim manufacturer to switch 100% of its production to aniline-free* indigo dyeing.

Absolute Denim is a Thailand-based denim manufacturer producing high quality denim with a focus on eco-friendlier materials and processes. The company can produce up to 2 million meters of denim per month (that's approximately 1.5 million pairs of jeans!), for customers that include some of the biggest brands and retailers in the world.

Archroma’s Denisol® Pure Indigo 30 liquid dye was first launched in May 2018 as a non-toxic way to produce the traditional, iconic indigo blue that consumers associate with denim and jeans.

During production, some of the aniline stays locked into the indigo pigment and is difficult to wash off the fabric. The remainder of the aniline impurity, approximately 300 metric tons annually, is discharged during dyeing. This can be an issue as aniline is toxic to aquatic life. In addition, exposure levels to factory workers can be high. As a result of its toxicity (more hazardous than alkylphenols) it is now starting to feature on the restricted substance lists (RSL) of some major clothing brands and retailers.

The new Denisol® Pure Indigo 30 liq was therefore developed as an aniline-free* indigo solution for designers, manufacturers and brand owners who long for authentic indigo inspiration.

Archroma tested Denisol® Pure Indigo at Absolute Denim mill in Thailand. Archroma wanted to be sure that the new indigo dye would perform exactly the same as conventional indigo.

James Carnahan, Head of Sustainability at Archroma, comments: “At Archroma we continuously challenge the status quo in the deep belief that we can make our industry sustainable - but we cannot do it alone. Without forward-thinking manufacturers such as Absolute Denim to consciously adopt these eco-advanced innovations in their daily production, like our aniline-free* Denisol® Pure Indigo, we will not be able to move this industry forward on our resource-constrained world we live in. As consumers are increasingly aware of, and concerned about, climate change and ecological threats, this is not only the right thing to do - it is also good for business.”

“Deep down inside most of us want the world to be a better place for our loved ones and for future generations,” insists Vichai Phromvanich, Board Member, Absolute Denim, “starting with how we live, what we eat, what we wear, still trying to be cool, fashionable, still trying to be environmentally conscious. Archroma’s aniline free indigo project is therefore something we as a new generation manufacturer have supported from the beginning, by opening our doors for tests in the project phase, and now by sending out our articles to many of our customers. For us, after all, a nice pair of jeans looks even nicer without aniline!”

Archroma breaks new ground with new aniline-free* indigo for denim

Archroma, a global leader in color and specialty chemicals, has presented an aniline-free* denim indigo dye at the recent Planet Textiles 2018 Conference in Vancouver, Canada. The brand new dye provides a non-toxic way to produce the traditional, iconic indigo blue that consumers associate with denim and jeans.
Currently, aniline impurities are an unavoidable element of producing indigo-dyed denim. Unlike other chemical impurities, aniline is locked into the indigo pigment during the dyeing process and therefore cannot be washed off the fabric.

Currently, aniline impurities are an unavoidable element of producing indigo-dyed denim. Unlike other chemical impurities, aniline is locked into the indigo pigment during the dyeing process and therefore cannot be washed off the fabric.

Scientific testing has shown that aniline impurities are toxic to humans, causing skin allergies, damage to major organs and genetic defects, as well as being linked to cancer. Aniline is also toxic to aquatic life, which is an issue as two thirds of the 400 metric tons of aniline waste on an annual basis ends up in the environment as wastewater discharge. The toxic chemical is therefore starting to feature on the restricted substance lists (RSL) of some major clothing brands and retailers. “We have tested denim garments and found that aniline concentrations are frequently higher than expected,” says Alexander Wessels, CEO, Archroma. “This could put some manufacturers over the limits agreed on their RSLs.”

True to its commitment to take on innovation challenges, Archroma decided to take a closer look at the issue with its R&D experts, and developed an alternative system that is aniline free*.
“At Archroma, we continuously challenge the status quo in the deep belief that we can make our industry sustainable,” continues Alexander Wessels. “By removing a hazardous impurity from the denim supply chain, we aim to protect the workers who create denim, the consumers who wear denim, and the environment with cleaner waterways.” The Denisol® Pure Indigo 30 dye is the latest in a long line of sustainable innovations for denim started in 2009. That year, Archroma introduced its ‘Advanced Denim’ technology which uses up to 90% less water during the dyeing process. “Being not indigo but sulfur based, ‘Advanced Denim’ itself was an aniline free solution too!”, adds Alexander Wessels. For designers and brand owners who long for authentic indigo inspiration, the new Denisol® Pure Indigo 30 now also makes it possible to produce indigo-dyed denim without high levels aniline impurities. Archroma successfully tested Denisol® Pure Indigo 30 at Absolute Denim mill in Thailand. “During the testing everything performed exactly the same as it would with conventional indigo,” says Vichai Phromvanich, Board Member, Absolute Denim. “There was just one important difference: no aniline.”

“We’ve had an overwhelming positive reaction from the industry in sneak previews and during the launch at Planet Textiles,” continues Alexander Wessels. “As a responsible industry leader, we believe it’s important to actively look for eco-advanced solutions that are attractive and at the same time cost-efficient for clothing brands, retailers and end-consumers.”

Archroma will make the Denisol® Pure Indigo 30 dye in the most sustainable way as possible. The new dye will be produced in Archroma’s facility in Pakistan, a plant that made the headlines in 2012 for being what Archroma believed to be the industry’s first zero liquid discharge plant.
