From the Sector

Denim manufacturers employing Monforts technologies showcased their latest activities, including sustainable fabric manufacturing, new advances in fibres, dyes and chemicals, as well as process and supply improvements and recycling options, at Première Vision’s Digital Denim Week, held from July 5-9.

The users of Monforts equipment included AGI Denim (Pakistan), Azgard 9 (Pakistan), Berto (Italy), Bossa (Turkey), DNM (Turkey), Kilim (Turkey) and Orta (Turkey).

The new Naveena Denim Mills (Pakistan) Holistic collection, for example, employs a suite of sustainable materials such as organic cotton and post-consumer and post-industrial waste cotton that has been shredded and recycled at its in-house unit in Pakistan.

Supply chain transparency is also becoming increasingly important, and Turkey’s Bossa is now sharing information on its dyes, energy sources and recycled content use with its customers. For organic cotton in particular, Bossa provides QR codes with which brands can identify the names of individual farms and their locations, as well as details such as the origins of specific seeds and the use of irrigation by growers.

Turkey’s Orta’s new Denim Route – inspired by the historical Silk Road for trade between the East and West – is an interactive supplier map detailing the regions from which it sources cotton, dyestuff, chemicals and various fibres to complement its other transparency initiatives.

Meanwhile, a living and breathing piece of clothing that absorbs carbon dioxide while simultaneously producing oxygen was introduced at Digital Denim Week 2021 by Azgard 9 (Pakistan) .

• Borealis deepens partnership with innovative recycling solutions provider Renasci N.V., acquiring a 10% minority stake in the Belgium-based creator of the Smart Chain Processing (SCP) concept
• Deal supports Borealis integrated approach to achieve a true circular economy of plastics in the most eco-efficient way, as defined by its circular cascade model
• EverMinds™ in action: Game-changing collaboration to accelerate plastics circularity

Borealis announces that it has entered into a multi-dimensional partnership with Renasci N.V., a provider of innovative recycling solutions and creator of the novel Smart Chain Processing (SCP) concept. The partnership is another key enabler for Borealis to realise its ambitions to bring circular base chemicals and polyolefins to market, and to deliver on its promise to bring 350 kilotons of recycled polyolefins into circulation by 2025.

SCP concept leaves no waste behind
The SCP concept developed by Renasci is a proprietary method of maximising material recovery in order to achieve zero waste. It is unique because it enables the processing of multiple waste streams using different recycling technologies – all under one roof. At the newly-built Renasci SCP facility in Oostende, Belgium, mixed waste – plastics, metals, and biomass – is automatically selected and sorted multiple times.

After sorting, plastic waste is first mechanically recycled, and then in a second step any remaining material is chemically recycled into circular pyrolysis oil and lighter product fractions, which are used to fuel the process.

Other types of sorted waste such as metals and organic refuse are further processed using other technologies. In the end, only 5% of the original waste remains, and even this residual material is not landfilled, but used as filler in construction materials. Because of this extremely efficient way of processing, the overall CO2 footprint of these waste streams is greatly reduced – yet another advantage of the circular SCP concept.

The cascade model is Borealis’ integrated circular approach
Borealis circular cascade model sits at the heart of its ambition to achieve a truly circular economy, by combining carefully chosen technologies in a complementary and cascading way to achieve full circularity. In this way, Borealis aims to give plastic products multiple lifetimes in the most sustainable way possible. Starting with optimising product design, first for eco-efficiency, then for re-use and finally for recycling. Once a product has reached its end of life, we must close the plastics loop: first with mechanical recycling to make products with the highest possible value, quality and lowest carbon footprint; then utilising chemical recycling, as a complement to mechanical recycling, to further valorise residual streams which would otherwise go to incineration, or even worse to landfills. The valorised material from mechanical and chemical recycling is then processed with Borealis Borcycle™ recycling technology consisting of Borcycle M for mechanical recycling and Borcycle C for chemical recycling, providing high quality solutions for more sophisticated applications, such as food packaging and healthcare.

The SCP concept is aligned to Borealis’ ambition to close the loop on plastic waste as encapsulated in its circular cascade model.

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.

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

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.

Archroma, a global leader in specialty chemicals towards sustainable solutions, announced that it has become a The BHive® partner to help foster chemical compliance and management across the textile supply chain.

The BHive® is an innovative digital chemical management platform that provides at-a-glance information about chemical products to its users. It was developed by GoBlu International Ltd. to allow manufacturing facilities to easily create digital inventories of the chemical products used onsite using a smartphone. They can identify in a matter of seconds which products meet sustainability requirements of their brand and retail customers, who they can share this information with as well. This enables brands and retailers to achieve full transparency about the chemical use in their global supply chain. Now, over 30 international fashion brands and 500 factories are partnered with The BHive® to drive sustainable chemistry in the textile and fashion industry.

More than 2000 Archroma chemical products and dyes are now included in The BHive® database.
The company has been very active in the past few years in developing solution systems and innovations in line with the 3 pillars of 'The Archroma Way to a Sustainable World: Safe, efficient, enhanced. It’s our nature'.

Paul Cowell, Head of Archroma’s Competence Centers for Brand & Performance Textile Specialties, explains: "With the pandemic crisis, textile manufacturers are experiencing numerous logistic bottlenecks and challenges. With The BHive®, our partners have now an additional access path to the information about chemical usage and compliance for the Archroma products they keep at their facilities."

Swedish commission dyeing company 7H Färgeri is looking to propel itself to the forefront of sustainable fabric production with the installation of the first industrial scale imogo Dye-Max spray dyeing line.
Currently under construction, the line will be delivered in the first week of March to the 7H plant close to the Swedish city of Borås. It will have a full working width of 1.8 metres with an operating speed of up to 50 metres for the reactive dyeing of cellulosic fibre-based fabrics. In addition, it will be capable of carrying out the application of a wide range of fabric pre-treatments and finishing processes, providing the company with unbeatable flexibility in production.

A proven Mini-Max laboratory unit for pre-determining application volumes and colour matching will also be delivered as part of the contract.

With the potential to slash the use of fresh water, wastewater, energy and chemicals by as much as 90% compared to conventional jet dyeing systems, the DyeMax has gained considerable attention since the concept was outlined and a prototype machine constructed in 2019.

Pilot scale trials have subsequently been carried out with many well-known international textile companies and their brand partners.
The application unit of the Dye-Max consists of a closed chamber containing a series of spray cassettes with precision nozzles for accurate and consistent coverage, in combination with the patented imogo Pro Speed valve that controls the volume to be applied.

Control and precision
“We are achieving an extremely low liquor ratio of around 0.5-1 litres per kilo of fabric and we fully control the pickup, applying precisely what is required to the specific fabric,” says imogo founding partner Per Stenflo. “Compared to traditional padders there is no contamination of the dyebath or dilution of the dye liquor to worry about.
Fast changeovers with virtually no waste together with a high production speed enable a high productivity and unmatched production flexibility. The system is also equipped with an exhaust system and droplet separator to ensure that the environment around the unit is safe and free from particles.

The imogo Mini-Max meanwhile frees up valuable production time by avoiding wasteful pre-runs. The user simply sets the recipe with the Mini-Max and transfers the parameters to the Dye-Max recipe database for the system to be fully production ready.

7H Färgeri was founded in 1935 and has established itself as the Nordic region’s most complete dyeing and processing plant, specialising in technical and functional textiles for the automotive and soft furnishings sectors, as well as functional and protective clothing.

The family-owned business is now run by brothers Johan and Peter Engelmann.
“We are pleased to be pioneering a sustainable first for the dyeing industry,” said Johan Engelmann. “Our goal is to offer the market products and services with the highest quality in the most climate-smart and sustainable way, and imogo’s spray technology will give us the opportunity to offer innovative new services and products to both existing and new customers. It will be a very exciting journey.”

World Congress on Textile Coating
On February 12th Per Stenflo will make a presentation entitled ‘Transforming Textile Dyeing’ during the online World Congress on Textile Coating which is held over four days, between February 11th and 19th.
