• Circular economy at Kelheim Fibres: Examples of innovation from raw material, product design and all the way to “end of life”

Kelheim Fibres, the world's first viscose fibre manufacturer with an EMAS-certified environmental management system, is continuously working on optimising its special fibres. These can be functionalised as needed - in many cases to save further processing steps (such as dyeing or coating) and thus energy, water and chemicals - and are completely biodegradable at the end of their product life in a short time (according to OECD Test 301 B).

Currently, the specialists in Kelheim are working on the development of alternative raw materials for the production of viscose fibres, such as recycled cellulose as well as other cellulose-containing starting materials. One approach to closing the product cycle in the textile sector is the use of pulp produced from recycled post-consumer waste materials.

In production, Kelheim Fibres focuses on resource conservation by minimising emissions and waste through closed-loop recovery systems, as well as through highly efficient energy generation and the corresponding operation of the plants.

Dr. Roland Scholz, Project Manager Fibre and Application Development at Kelheim Fibres, will present details of this on Wednesday, 15 September, at 5.50 p.m., in Hall B of the 60th Dornbirn GFC WEBINAR WEEK.

• A new capsule collection colored only using plants and natural elements, signed together by Tonello and WRÅD

A capsule collection of exclusive garments was born, happy, totally natural, healthy and sustainable, free of chemicals hazardous for the environment or humans, hypoallergenic and gentle on the skin, the result of a responsible process, 100% GOTS certified organic cotton.

A collection made possible by the talents of WRÅD and Wake, the innovative organic dyeing system developed by Tonello: healthy for people and for the environment, because it uses only plants and vegetable waste, such as flowers, berries, peels and roots, which are left to dry and then infused, without using harmful chemical additives. It is easy to use, almost like preparing an herbal tea: it is, in fact, a radical paradigm shift.

The naturalness of the pigments used and the desire to create a support that would highlight the real color of emotions: these were the points that unite WRÅD and Tonello, realities that are also physically close, united by the authenticity of their evolutionary promises of change and transformation.

The colors on the garments are alive. Sensitive to light, over time they tend to fade to a lower tone, becoming increasingly sober and authentic, like those who choose to wear these manifesto-garments, which invite, quietly, and with grace and subtlety, a gentle revolution: in the name of respect for the environment and the equilibrium between people and nature.

Archroma announced that the soon-to-be 5’760 color references of its Color Atlas library are made available within its ‘Datacolor TOOLS’ platform, an easy-to-use color quality control application for industries where color accuracy is a critical component of overall product quality.

Datacolor® provides color management solutions that empower customers to make objective, cost-effective and smart color decisions, in applications such as textile & apparel, paint & coatings, plastics, photography, design and many others. The perfect integration of its instruments and software help formulate, measure, control and communicate color, and its state-of-the-art algorithms reproduce color on materials and displays.

The Color Atlas was launched in 2016 to provide fashion designers and stylists with off-the-shelf color inspiration that can be implemented in production with just a few clicks.

Today, the Color Atlas contains 4’320 colors applicable on cotton poplin, almost the double compared to similar tools available to textile and fashion specialists. Technical support is available to designer, manufacturers, as well as brands and retailers, through Archroma’s global offices - for every single color from its selection to its implementation in production. Engineered color standards empowered by NFC technology are also available for all colors and reproducible in production.
Archroma also just launched a similar tool with 1,440 colors on polyester. Both libraries will be available in the ‘Datacolor TOOLS’ platform for color searching.

Each color from the Color Atlas by Archroma® is available for purchase from Archroma as an ‘Engineered Color Standard’, precise digital data and access to global dyeing technical support.

With that, the brands, designers and mills using the ‘Datacolor TOOLS’ platform will have at their disposal the ability to search the 5’760 colors of the Color Atlas by Archroma®, to quickly find colors for their seasonal color palettes.

Combining expertise for more sustainable fashion
Ever wonder how much water was used to make your favorite cotton T-shirt? About 2,700 liters, or roughly three years of drinking water. What first comes to mind is probably the water that was essential to growing the cotton crop. Surprisingly, cotton is a drought-tolerant plant, and often less recognized is the strain that can be put on water resources to dye cotton textiles.

Progress is being made across the industry to lessen the strain on our precious water resources. Over the past several years, Dow collaborated with Cotton Incorporated to research and validate their product, ECOFAST™ Pure Sustainable Textile Treatment, that can help drastically reduce water and chemical use during the dyeing process. Major fashion brands are integrating it into their supply chain to dye more sustainably, without sacrificing color or quality.

Problem
Cotton dyeing is very resource-intensive and puts strain on local waterways. A large amount of water is used in the dyeing process – up to 5 trillion liters a year, or nearly enough to supply all of humanity with drinking water. Significant amounts of chemicals and dye are needed to get the desired colors consumers expect too. This is part of the reason textile mills account for 20% of industrial water pollution globally. Wastewater from the dyeing process can be polluting and require costly treatment and these challenges are found in regions that already face water scarcity.

Solution
Reforming processes in an industry as established as textiles is no easy feat. Collaboration across the sector is needed to bring about sustainable change. With that in mind, Cotton Incorporated approached Dow. They wanted help scaling a cotton technology to support more sustainable textile dyeing.Leveraging Cotton Incorporated’s industry expertise and Dow’s material science knowledge, they worked together to understand and validate the benefits of our patented ECOFAST™ Pure Sustainable Textile Treatment.

How can colors be more responsible?  
ECOFAST™ Pure is a pretreatment applied before the dyeing process to produce cationic cotton. This means the charge of cotton is permanently changed from negative to positive, so it acts like a magnet to attract negatively charged dye to the material. How does that benefit the textile mill? It significantly decreases the amount of water, chemicals, dye and energy needed to color cotton. A third party reviewed and validated life cycle assessment, available by request, helped further prove the benefits.

• 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⁾.

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⁾.

(1) Below limits of detection according to industry standards (tested & proven).
(2) Based on 15 minutes of work to produce one pair of jeans, produced over 8-hour working days and 300 working weeks per year.

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.

Flexibility, product uniformity and automation are the keys to success for coating businesses in today’s rapidly-changing technical textiles industry, explained Jürgen Hanel, Monforts Head of Technical Textiles, at the recent 1st World Congress on Textile Coating.

Introducing the latest Montex®Coat magnetic roller coating option to virtual delegates from around the world at the conference organised by International Newsletters, Hanel explained why this technology makes perfect sense now

“The magnetic roller system allows a wide range of coatings and finishes to be carried out, while being easy to handle for operators and much easier to clean at the end of the process,” he said. “It provides textile finishers with an expanded range of options due to the fully-adjustable positioning of the magnet within the roller and with four different magnet positions possible, can be set to operate both as a direct coating system and as an indirect coater.”

With traditional dip coating systems, he added, as well as with many standard knife coating technologies, there is always a difference in the tension between the centre and the edges of the wide width fabrics being treated – and hence the amount of pressure with which the coating is applied. With the use of a magnetic roller, equal pressure is applied across the full width of the fabric, with consistent results even at wide widths of over 2.4 metres. In addition, adjusting the roller surface, rather than changing the coating formulation to match the required add-on and viscosity for each coating effect required, leads to much higher output from the line.

Cleaner and less wasteful
The contribution of such flexible and resource-saving new technologies to a cleaner and less wasteful textile industry was a key theme at the congress – held virtually across the four afternoons of February 11th, 12th, 18th and 19th – as was digitalization and the many advantages it is providing.

“A typical integrated Monforts coating line is automated from the inlet feed to the winder,” Hanel told delegates. “Adjustments can also be made simply and easily from the touchscreen and with the new hand-held remote controller which has recently been introduced for the Montex®Coat unit.”

Manual adjustment, he added, is time consuming and needs the attention of an experienced operator or the reproducibility will not be accurate between coating operations. The adjustment by motors allows each coating to be stored and downloaded again for 100% reproducibility.

The motors can be fully controlled from the touchscreen and all necessary adjustments carried out remotely, making switching from one process to another extremely quick and easy.
The accuracy that is now being demanded by today’s most exacting customers is met with an optional carbon fibre roller – especially in dealing with the winding tension required in the processing of materials such as prepregs for composites and other heavyweight fabrics. Typical applications for the Montex®Coat include the finishing of tents and awnings, black-out roller blinds and sail cloth, automotive interior fabrics and medical disposables. Full PVC coatings, pigment dyeing or minimal application surface and low penetration treatments can all be accommodated.

“The World Congress on Textile Coating was characterised by some very stimulating presentations and forums between the speakers and a global audience of textile specialists,” Jürgen Hanel concluded. “It truly reflected the high level of positive changes now taking place in not just textile coating, but the entire textile industry. I look forward to the next edition, which hopefully will be a face-to-face event for even deeper level discussions and debate.”

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."
