From the Sector

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.

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 8 years of leading the way to a sustainable world, with innovations and solutions aimed at creating added value sustainable for its partners, consumers and the planet.

Archroma came to life on 1st October 2013 from textile, paper and emulsions businesses acquired from Clariant by SK Capital Partners.
Building on decades of commitment to developing safer eco-friendlier chemistry, Archroma has become in the past 8 years a prominent name for more sustainable colors and performance, collaborating with leading brands such as Primark, G-Star, Patagonia, Esprit and more.

Archroma has introduced innovations, such as the EarthColors® made from non-edible plant waste from the food and herbal industry, Denisol® Pure, an indigo for aniline-free* denim, aniline being a category 2 carcinogen substance, and Smartrepel®, a PFC-free* water repellent solution. The company is also about to launch a new plant-based softener.

The company started to develop holistic solutions designed to bring innovation and performance, whilst reducing the impacts on water, energy and other natural resources. The savings generated by these 70+ system solutions are demonstrated by Archroma's proprietary ONE WAY Impact Calculator, a tool launched in 2012 and continuously upgraded to simulate and optimize the footprint of application processes.

Archroma also recently launched CASUAL X SMART, a sulfur dyeing system for trendy wash-down effects to make clothes that look smart at home and at work. The colors won't fade in the washing cycle, and the application process allows resource savings of up to 33% water, 21% energy and 35% chemical usage compared to a benchmark reactive & pigment garment dyeing.

With ONE WAY, a brand can calculate how much impact their current production and the Archroma Way collection will have on water, energy, chemical, raw material or CO2 footprint.

Archroma, a global leader in specialty chemicals towards sustainable solutions, announced the release of its Sustainability Report for its fiscal year 2020.

Prepared again in accordance with the Global Reporting Initiative (GRI) standards, and building on a strong track record, the report outlines the company’s progress on its priority sustainability topics, such as human health and environmental safety, resource efficiency, sustainable sourcing and product stewardship, as well as diversity & inclusion, and talent management.

For the first time Archroma conducted a survey with its stakeholders to confirm the relevance of the sustainability topics covered in the report. These include biodiversity, occupational and product safety, and fair labor practices, as well as maybe less expected topics such as compliance, economic performance, and culture.

Archroma, a global leader in specialty chemicals towards sustainable solutions, and Jeanologia, a world leader in sustainable and efficient technology development, today announced the launch of ‘Pad-Ox G2 Cold’, a water-saving dyeing process at room temperature for casual looks.

Archroma initially introduced its eco-advanced Pad-Ox dyeing process for woven fabrics, and then used it as part of its ADVANCED DENIM concept. By combining the oxidation and fixation steps, it is possible to shorten the dyeing process and thus realize substantial resource savings in water, wastewater, cotton waste, and energy.

Over the years the company has worked with its textile manufacturers and partners to improve the Pad-Ox process, in particular woven applications such as chinos and casual wear. To achieve maximum positive impact, Archroma is using its Diresul® range of low sulfide sulfur dyes and, more recently, its innovative plant-based range of EarthColors®. A wide selection of dyes from these two ranges have received the Cradle-to-Cradle Product Innovation Institute’s Platinum Level Material Health Certification.

Meanwhile, Jeanologia has been working on the technology side, with laser and eco-finishing solutions for more than 25 years, accompanying the textile industry on their way to producing with zero discharge. In 2008, the company introduced its G2 Dynamic the first ozone treatment for continuous fabric that dramatically reduces the amount of water and chemicals used, while at the same time saving costs at the mill and eventually at the garment finishing facilities. This technology makes fabric more stable and consistent and prepares the fabric better for the use of other technologies like laser. This machinery can be used along with Pad-Ox technology to help cleaning fabric thus improve fastness results. While it allows process to work at room temperature.

Project focus on water saving
Archroma and Jeanologia therefore understandably decided to team up and combine their expertise in sustainable dyeing and finishing technologies. The objective of the project was to improve the Pad-Ox dyeing process even further, in particular in one area that still offered room for positive impact: temperature and fastnesses.

The new ‘Pad-Ox G2 Cold’ dyeing process works thanks to the insertion of very small machinery into the existing finishing range process, using cold processing and thus operating with much less water, carbon footprint and energy than traditional benchmark fabric finishing processes, whilst retaining the water and other resource savings offered by the Pad-Ox technology.

Maximum savings can be achieved by mills and garment manufacturers who wish to switch from a conventional dyeing process straight to ‘Pad -Ox G2 Cold’ to obtain high quality fabrics for comfortable and casual wear.

Reinach, Switzerland, and Westlake, Ohio, 2 February 2021 - Archroma, a global leader in specialty chemicals towards sustainable solutions, today announced a strategic partnership with technology innovator CleanKore, aiming to advance sustainable dyeing processes throughout the denim supply chain.

The agreement will allow Archroma and CleanKore to promote the benefits of each other’s technologies. This includes Archroma’s robust catalog of dyes and specialty chemicals along with CleanKore’s patented process of dyeing yarns at the denim mill that completely eliminates the need for potassium permanganate (PP) spray and laser booster to achieve the bright white abrasion effect in the garment finishing process. The result is a large and circular bright white core with a small ring of indigo dye. The technology does not just eliminate the chemicals associated in the PP spray and laser process, which is much safer for denim workers, it also allows to save significant amounts of water and energy throughout the manufacturing process from fabric to garmenting.

CleanKore initially looked at eliminating potassium permanganate due to its being classified as hazardous if inhaled or ingested, or in case of contact with the skin or the eye. It is also considered very toxic to aquatic life. No new equipment or capital expenses are needed to implement the CleanKore technology, which works on all denim fabric, including dark indigo, sulfur top/bottom and sulfur black.

This is where Archroma comes into the picture. Its global technical team of denim coloration specialists will provide support to denim mills seeking to implement the CleanKore technology and develop the desired looks and effects - with the right colors and chemical systems for their production set-up.

CleanKore estimates that the technology allows to save up to 15 liters of water per garment, or the equivalent to the drinking needs of 5 people per day, and up to 0.51 kWh of energy per garment, or the equivalent of five 100-watt light bulbs on for 1 hour. The CleanKore technology also leads to a 10% to 20% increase in production throughput, as a result of a faster garment wash-down and the elimination of PP spray.

For CleanKore CEO Darryl Costin Jr., the announcement comes at an ideal time for CleanKore: "We have successfully proven the technology with mill partners such as Arvind and other denim mills in Pakistan, Bangladesh, China, Vietnam, Thailand and the United States. The response from the industry has been overwhelmingly positive. Having a partner in Archroma, one that is highly respected for their innovation and emphasis on sustainability throughout the industry, will allow us to take CleanKore to the next level.”

Umberto Devita, Global Indigo Manager at the Archroma Global Competence Center for Denim & Casualwear, adds: "CleanKore is perfectly aligned with the 3 pillars of 'The Archroma Way to a Sustainable World: Safe, efficient, enhanced'. 'Safe' through the elimination of a potentially harmful substance and the protection of the denim workers, 'Efficient' through the reduction of resource consumption, improved productivity and cost-effective profile. And 'Enhanced' through the gorgeous colors and effects allowed with Archroma's innovations and systems, in particular our aniline-free* Denisol® Pure Indigo and Diresul® sulfur dyes. We look forward to help promoting an innovation that will help with many of the challenges facing our denim customers throughout the world. Because it’s our nature."

Archroma, a global leader in specialty chemicals towards sustainable solutions, today announced the release of its third Sustainability Report.

Prepared again in accordance with the Global Reporting Initiative (GRI) standards, and covering Fiscal Year 2019, the report outlines the company’s progress on its priority sustainability topics, such as human health and environmental safety, resource efficiency, sustainable sourcing and product stewardship, as well as diversity & inclusion, and talent management.

All activities described in the report support the 3 pillars of “The Archroma Way to a Sustainable World: Safe, efficient, enhanced. It’s our nature." This approach is the company’s guiding light in challenging the status quo to making its operations and its value chains sustainable.

“As our industries navigate through the COVID-19 pandemic, the temptation for some will be to push back on the urgent need to address the climate crisis. We cannot allow that. Because after all, it's our nature”, Heike van de Kerkhof, CEO of Archroma, comments.

• Esprit selects EarthColors® by Archroma for its newest ‘I AM SUSTAINABLE’ capsule collection

Archroma, a global leader in color and specialty chemicals towards sustainable solutions, today announced a new collaboration with Esprit, the global fashion clothing brand, who selected the EarthColors® range for its ‘I AM SUSTAINABLE’ capsule collection.

Esprit creates laid-back, high-quality essentials that reflect its core values of sustainability, equality and freedom of choice. The brand developed its first eco-conscious collection made of 100% organic cotton, back in the early 90’s.

Archroma’s EarthColors® range came to public attention for being the Gold Winner of the OutDoor Industry Award 2017, Sustainable Innovations category.

The range is regularly featured by brands such as Kathmandu, G-Star and Ternua, who are willing to explore truly innovative and authentic color options for more eco-conscious casual wear collections.
Archroma’s EarthColors® is a line of patented plant-based dyes, sourced from up to 100 percent renewable resources.

Archroma developed EarthColors® using non-edible waste products, from agriculture and herbal industries, to replace petroleum derived raw materials; which are the conventional raw materials used to synthesize dyes currently. This gives brands an alternative when looking for more natural ways of dyeing garments.
The collection is available online: www.esprit.eu/earthcolors.

After an intense dialogue and a series of meetings during the past year between the ZDHC Board of Directors and the GCIRT, an alignment was gained on ZDHC organisational commitments and a mutual understanding of the role of chemical suppliers within the ZDHC Programme. This opens the doors for broader, more active distribution of chemistry expertise and implementation support of textile dye and leather chemical manufacturing industry in the ZDHC Programme.

The Global Chemical Industry Round Table (GCIRT), sent an open letter to ZDHC in May 2018 and is a group of the leading chemical solution providers in the textile and leather industry with the collective aim of driving the industry further to become more sustainable. GCIRT’s signatory’s engagement into the ZDHC Programme will support a faster transformation of the industry by taking complexity out of the supply chain and to find appropriate solutions for the industries’ requirements.

The GCIRT members are: ARCHROMA (Switzerland); CHT Germany GmbH (Germany); Colourtex Industries Private Limited (India); DyStar Singapore Pte Ltd (Singapore); Huntsman Textile Effects (Singapore); KISCO (Korea); Pulcra Chemicals Group (Germany); RUDOLF GmbH (Germany); TANATEX Chemicals B.V. (Netherlands).

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!”
