From the Sector

Stahl, an active proponent of responsible chemistry, has published its 2021 Environment, Social, and Governance (ESG) Report. The report outlines the company’s sustainable development ambitions and its achievements over the year. It also features Stahl’s ambitious climate mitigation targets for 2030, such as the transition to more renewable feedstocks.

The 2021 Stahl ESG Report is a cornerstone of Stahl’s commitment to reporting transparently on its progress toward a more sustainable chemicals value chain. This acknowledges the important role that industry must play in tackling climate change while enabling a higher quality of life for more people. A key focal point of the new report is a progress update on Stahl’s ESG Roadmap. Introduced last year, this ten-year plan outlines the company’s ESG commitments and targets for 2023 and 2030.
 
Climate action
Stahl is focused on mitigating climate change by reducing greenhouse gas (GHG) emissions from all activities over which it has influence. This includes investing in renewable energy and process efficiencies to lower the GHG emissions caused directly by Stahl’s own operations and the energy used to power them. On this point, progress was made toward the 2023 and 2030 targets in 2021, including a reduction in Scope 1 and 2 CO2 emissions of 15%. Also covered are Stahl’s indirect value-chain impacts, for example, from the raw materials it buys. Looking beyond Stahl’s direct environmental impacts and fostering greater supply-chain transparency will be vital for tackling emissions on a wider scale.

Creating responsible chemistry, together
In 2021, advances were made regarding the company’s diversity and safety targets, which are areas of continuous improvement. Stahl is committed to ensuring a safe working environment, as well as nurturing a diverse and inclusive workplace to continuously improve employee skills.

EcoVadis Gold rating
Fostering ethical behavior through exemplary leadership and governance is key to Stahl’s ambitions. Achieving the EcoVadis Gold rating was an important milestone in this respect. This well-established award reflects the company’s ongoing commitment to supply chain transparency and working with partners to improve the sustainability of its products and operations.

Archroma and Stony Creek Colors (“Stony Creek”), a manufacturer of traceable natural indigo dyes, announced that they have entered a strategic partnership to produce and bring to the market Stony Creek’s IndiGold™ high-performance plant-based pre-reduced indigo at scale.

Stony Creek extracts its dye from proprietary Indigofera plant varieties grown in partnership with family farms as a regenerative rotational crop.

Stony Creek Colors developed the new IndiGold™ concept as on of the world’s first pre-reduced natural indigo dyes, which was then developed with Archroma to offer a plant-based alternative to synthetic pre-reduced indigo. The dyestuff will be sold as a 20% concentration in a soluble liquid form that displays similar performance to comparable synthetic indigo products available on the market.

Stony Creek Colors evolved into an innovative leader in plant-based indigo due to its complete development of an improved agricultural value chain, from seed breeding and production to biomass harvest and extraction. The company has been selling its US grown indigo to denim mills since 2015.

The pre-reduced plant-based indigo partnership took root in 2020 when Stony Creek was looking to work with like-minded partners to produce the new dyestuff at scale. Archroma emerged as the ideal partner as the company is well known for its expertise in indigo manufacturing and application, as well as for its commitment to transform the denim industry towards creating better blue jeans.

Archroma immediately offered to support the idea of Stony Creek Colors with extensive pilot scale manufacturing trials and engaged with its network of denim machinery manufacturers to test the first samples in industrial conditions. The trials showed excellent coloration and the typical indigo wash down, as with synthetic indigo. Archroma will produce the first batches of IndiGold™ in Salvatierra, Mexico, and has other locations where the product could be made. The company will support Stony Creek Colors through its manufacturing and logistics capabilities, and its expertise in denim dyeing with customers using pre-reduced indigo.

While this development was underway, the global innovation platform Fashion for Good selected Stony Creek Colors as an innovator in its global Innovation Program. The program connects brands with innovators to work together to test, validate and ultimately scale disruptive innovations in the fashion industry to drive positive impact. Through the program, Fashion for Good facilitated a collaboration between brand partner Levi Strauss & Co. and Stony Creek Colors which was announced in December 2021. The partners will pilot the use of IndiGold™ in denim mills at scale, with the goal of unlocking key learnings around shade application and other efficiencies of this new dyestuff.

• Long-awaited metal-free* and halogen-free* NYLOSAN® S NAVY and BLACK COLORS for Sportwear
• Iconic black and navy polyamides of major sportswear brands can finally be perfectly matched with safer dyestuffs
• Significant resource savings when dyeing with Archroma new signature CONSCIOUSLY DEEP system

Archroma, a global leader in specialty chemicals towards sustainable solutions, today announced the addition of two new metal-free* and halogen-free* acid dyes in its Nylosan® S range.

Dark shades represent approximately 80% of the outdoor and sportswear textile market, which is also under pressure to offer more sustainable articles. In this context, the new Nylosan® Navy S-3R and Black S-3N, especially developed by Archroma for polyamides and blends, meet four long-standing market demands for blacks and navies.

• First, the Nylosan® S range offers metal-free* alternatives to dyestuff generally used to dye polyamide and nylon and which usually contain metals. The new Nylosan® Navy S-3R and Black S-3N are taking the industry standard one step further by offering a halogen-free* option to those manufacturers, brands and retailers who are looking to offer the safest grade available.
• Second, the Nylosan® S range now comprises a wide gamut of colors, with these new dyes targeting the color matching and fastness specifications of the iconic blacks and navies of major sportswear brands. In order to support this color matching process, Archroma makes available the colorimetric dye primaries for the mills in order to (re)match the color standards.
• Third, the new navy and black dyes display the same color constancy as the dyes used in many leading color standards, which means the navy and black colors created with Nylosan® S range will be non-metameric to the color standard under multiple light sources, whether artificial or natural, indoor or outdoor.
• And fourth, the introduction of the new Nylosan® Black S-3N makes dyeing a metal-free* black on polyamide finally possible – something that was not available before.

Both dyes display the other usual features allowed of the Nylosan® S range, i.e., high fastness and buildup, and a wide shading gamut for industry-leading metal-free* acid dyes. They are REACH registered and bluesign® approved.

In addition, with the new Nylosan® Navy S-3R and Black S-3N at the core of its new CONSCIOUSLY DEEP system, Archroma is offering another very welcome benefit in the production of polyamide articles: resource saving. As most sportswear manufacturers and brands know, creating durable dark colors on nylon is a complex process that uses massive amounts of water and energy. Archroma therefore designed the new CONSCIOUSLY DEEP system to allow a highly efficient scour dyeing process reduced from 6 to 2 baths. This results into reducing the process time by up to 36%, water consumption by up to 64%, energy by up to 46%, and CO2 emissions by up to 41% compared to conventional benchmark process.

Sustainability has become a major trend in the global home textiles industry. It is more common nowadays to find natural and sustainable fibres in an extensive range of home furnishing products. From this angle, the Lenzing Group (Lenzing) will take led in a brand new pavilion at Intertextile Shanghai Home Textiles – Spring Edition. Lenzing is the world’s leading manufacturer of renewable specialty fibres, and will highlight the latest eco-friendly fibres that can meet the ever-rising sourcing demand. The fair is set to take place from 14 – 16 April 2022 at the National Exhibition and Convention Center (Shanghai).

As an upswing from the growing public awareness of environmental issues, consumers are now more willing to switch to sustainable products. According to a CottonWorks’ survey, 90% of the interviewed Chinese consumers want their home textiles to be environmentally friendly[1]. It also found that more consumers are paying attention to the fibre content that can deliver safe and sustainable home textiles.
Furthermore, the Chinese government’s ‘Outline Of the Development of the Textile Industry during the 14th Five Year Plan’, also encourages the acceleration of low cost, functional and sustainable renewable fibres in the local textile industry.

The Lenzing satellite pavilion: a one-stop platform for green home textile materials
To help home textile suppliers source a variety of eco-friendly materials efficiently, one of the fair’s long-time exhibitors is set to form a new pavilion at the upcoming Spring show. Lenzing, the Austrian brand widely known for its ecologically responsible production of specialty fibres made from renewable raw material wood, gathers seven of its local downstream supply chain manufacturers to showcase their renewable products.

Mr David Dai, Senior Commercial Director Textile China of Lenzing spoked about why they decided to organise a new pavilion at the show: “As we received positive feedback from our pavilion at Intertextile Shanghai Apparel Fabrics, our business partners from the home textile supply chain were hoping for a similar arrangement in this sector. We believe all the participating manufacturers can benefit from this pavilion by finding ways to better serve their clients and consumers.”

Brands in the Lenzing satellite pavilion will include:
•    Lenzing Group will introduce the first Carbon-zero TENCEL™ fibres which are CarbonNeutral™ certified products by Natural Capital Partner.
•    Botou Jinglun Textiles Co Ltd focuses on new fibre yarns. The company develops multi-component yarns for cotton, wool, silk and linen with combinations of MODAL, TENCEL™ fibres and various functional materials.
•    Fujian Yongtai County Huaerjin Textile Co Ltd provides high-quality, natural, renewable pure and blended yarns including TENCEL™ fibres, US cotton, Australian cotton, acrylic cotton, silk and other plant-based yarns.
•    Jiangsu Dasheng Group Co Ltd has one of the largest cellulosic fibre yarn spinning mills in China and focuses on producing top-quality home textiles.
•    Qingdao Textiles Group produces natural fibres, cellulose fibres, copper antimicrobial fibres and other nature-based materials for home and contract textiles.
•    Suzhou Zhenlun Spinning Co Ltd is an advanced enterprise specialising in regenerated cellulose yarns like ECO VERO, FSC Viscose, Circulose, Carbon Zero Yarn and more.
•    Ton Design Industrial Co Ltd produces medium and high-end bedding fabrics. The brand’s TENCEL™ Lyocell fibres and TENCEL™ fibres blend cotton series products are certified by Lenzing.
•    Wuxi Tianmu Extra Width Printing Dyeing Co Ltd mainly produces extra-wide, high-count and high-density down-proof fabrics and fabrics for bedding. The technique can handle different procedures for dealing with pure cotton, bamboo fibres, TENCEL™ fibres and other fibre fabrics.

In addition to the new pavilion, a number of other featured exhibitors will also showcase their sustainable products at the fair. This includes Cotton Council International (CCI) promoting US cotton fibres and cotton products, and Zhangjiagang Coolist Life Technology Co Ltd bringing their unique bedding products made from organic and environmental-friendly materials.

Up to the age of three, a baby uses around 5,000 diapers. Despite the convenient handling of common disposable diapers, parents are increasingly looking for a healthy and sustainable alternative to these products to avoid waste. In Germany alone, 10 million diapers are disposed of every day.

Ways to solve this dilemma, would be disposable products that are made from bio-based or biodegradable materials, or reusable products with a longer life span replace disposable products.

Founding team Luisa Kahlfeldt and Caspar Böhme combine both with their "Sumo Diapers." These cloth diapers are made entirely of sustainable materials while offering high performance and innovative design.

The Sumo Diaper is a fitted cloth diaper that consists of a waterproof cover and absorbent inserts. The cover is sewn in such a way that a pocket is formed: this is where the absorbent pad is inserted to prevent slipping.

To further enhance the performance of this absorbent pad, the Sumo team partners with the viscose special fibre manufacturer Kelheim Fibres, who brings decades of experience from the hygiene sector, especially for sensitive applications where high absorbency is required (such as tampons). Together, Sumo and Kelheim Fibres have developed a high-performance absorbent pad that uses no fossil materials.

The basis are functionalised specialty viscose fibres with adapted cross-sections. Needle-punched / thermobonded nonwovens with a blend of specialty viscose and PLA bicomponent fibres were chosen to ensure the product's washability. PLA stands for polylactic acid made from natural and renewable raw materials. By combining nonwovens, usually found mainly in the single-use sector, with reusable products, Sumo and Kelheim Fibres have chosen a completely new approach.

Inside the pad, the speciality fibres from Kelheim score with their special properties: In the distribution layer (ADL), the trilobal cross-section of the Galaxy® fibre forms capillary channels that enable efficient and optimized liquid distribution and thus optimum use of the capacity of the absorbent core, offering the lowest rewet values.

In the absorbent core, the segmented hollow fibre Bramante stores liquid not only between but also inside the fibre. The liquid remains there even when pressure is applied to the construction, providing excellent rewet values. Bramante can absorb up to 260% of its own weight in liquid. Cotton only achieves values of around 50% here.

The innovative nonwoven construction with the speciality fibres from Kelheim performs significantly better in tests in terms of air permeability, liquid absorption and rewetting than commercially available solutions made of synthetic fibres or cotton in knitted structures, and has earned Sumo diapers a place among the finalists for the IDEA® Long-Life Product Achievement Award.

The launch is scheduled for the first of May.

Industrietextilien müssen in der Nutzung hohen Anforderungen gerecht werden, was eine komplexe und oft auch ressourcenintensive Herstellung bedeutet. Wie sich in diesem Prozess Material und Energie sparen lassen, zeigt die Prozesskette „Industrietextilien“ des VDI Zentrums Ressourceneffizienz (VDI ZRE) anhand von Beispielen und aktuellen Forschungsvorhaben.

Die Anforderungen an Industrietextilien sind deutlich höher und vielfältiger als an solche Textilien, die im Alltag verwendet werden. Im industriellen Kontext eingesetzte Filterstoffe, Verpackungsmaterialien oder Beschichtungsträger werden meist aus hochspezialisierten Chemiefasern und unter hohem Einsatz von Energie und Wasser hergestellt. Oft besteht ein großes Einsparpotenzial.

Unternehmen bilden in der Regel nicht den kompletten Herstellungsprozess von der Faserherstellung bis zum fertigen textilen Produkt ab. Vielmehr spezialisieren sich die Unternehmen zunehmend auf einzelne Aktivitäten entlang der textilen Kette. Die Online-Prozesskette des VDI ZRE veranschaulicht den gesamten Herstellungsprozess und gibt gezielt Einblicke in die Einzelschritte. Beispiele verdeutlichen, welche Einsparungen andere Unternehmen bereits in einem ähnlichen Umfeld erreicht haben. Forschungsvorhaben zeigen, auf welche zukünftigen technischen Entwicklungen sich die Unternehmen einstellen sollten, um diese für ihre eigenen Innovationen nutzen zu können.

Natürliche Ressourcen sparen
Entlang des gesamten Herstellungsprozesses lassen sich Verbräuche von natürlichen Ressourcen reduzieren, unter anderem durch die Anpassung von Produktionsschritten oder den intelligenten Einsatz von Mess- und Regelungstechniken. Ein Beispiel zeigt, dass sich Schlichtemittel im Abwasser durch Ultrafiltration soweit anreichern lässt, dass es dem Schlichtmittelvorgang wieder zugeführt werden kann. Die Rückgewinnungsquote des Schlichtemittels beträgt in diesem Beispiel ca. 80 %. Dies hat zur Folge, dass auch der Chemische Sauerstoffbedarf (CSB-Fracht) im Abwasser um 30 bis 70 % sinkt.

Neben der konkreten Einsparung der Rohstoffe behandelt die Prozesskette auch, wie die eingesetzten Chemikalien verfolgt und analysiert werden können. So lässt sich ermitteln, auf welche Chemikalien aus Gründen des Umweltschutzes verzichtet werden sollte und welche Alternativen es gibt.

Die Prozesskette wird regelmäßig aktualisiert. Dabei ist das Kompetenzzentrum offen für einen Austausch mit Unternehmen, die Industrietextilien bzw. Teile davon herstellen. Erstellt wurde die Prozesskette im Auftrag des Bundesumweltministeriums.

• 76 KL/Day water saving by optimizing pH analysis process in dye vessels
• A step closer to achieving the ‘Huntsman Horizon 2025’ goal
• Potential savings of over Rs 10 crore or USD146,000 annually from the project

Huntsman Textile Effects, the global leader in innovative and environmentally sustainable dyes, chemicals, and digital inks, has successfully implemented a water conservation process to improve water efficiency and reduce net water usage at its Baroda facility, which is located in the western region of India. The initiative undertaken at the plant aims to save around 76 kilo liters of Reverse Osmosis water per day by modifying the phase sequence in the pH measurement program.

Water is used extensively throughout textile processing operations. The amount of water used varies widely in the industry, depending on specific processes operated at the plant, equipment used, and policies concerning water use. This conservation project at the Baroda Plant will have a potential savings of Rs 10 crore or USD146,000 a year for the organization.

Speaking on the development, Mark Devaney, Vice President Manufacturing and Operations Excellence, Huntsman Textile Effects said, “At Huntsman, we recognize the important role we play in creating a more sustainable future and are committed to the well-being of the communities where we operate, and the protection of the environment. We are continually looking for ways to improve the environmental footprint of our manufacturing sites and have been implementing numerous projects in recent years to reduce our water usage.”

“The team has done a detailed assessment of the pH analysis process in dye vessels, mapping the existing water usage and potential conservation method. After a brief study and several brainstorming sessions, we were able to adjust the phase sequence, resulting in conservation of Reverse Osmosis water by almost 76 kilo liters of water per day.” said Kavishwar Kalambe, Site Director, Huntsman Textile Effects. “This project directly contributes to Huntsman’s Horizon 2025 goals to reduce net water usage at facilities in water-stressed regions,” he added.

The current energy crisis is impacting on the competitiveness of the European textile and clothing industry. Because there are limited alternatives to the use of gas in different parts of the production process, production costs increase sharply. EURATEX asks the European Commission and Member States to urgently support the industry to avoid company closures. At the same time, we need a long term vision to move towards climate neutrality, while keeping the T&C industry internationally competitive.

EURATEX presented ten key requirements to Kadri Simson, European Commissioner for Energy, to develop such a vision:

1. The apparel and textile industry needs a safe supply with sufficient green energy (electricity and gas) at internationally competitive prices.
2. The transformation of industry requires access to very significant amounts of renewable energy at competitive costs. Additional investments in infrastructure will also be needed to guarantee access to new renewable energy supplies.
3. Until a global (or at least G 20 level) carbon price or other means for a global level playing field in climate protection are implemented, competitive prices for green energy must be granted at European or national levels (e.g. CCfDs, reduction on levies, targeted subsidies).
4. As the European textile and clothing sector faces global competition mainly form countries/regions with less stringent climate ambitions, it is of utmost importance that the European textile and clothing companies are prevented form direct and indirect carbon leakage.
5. EU-policy should support solutions, e.g. through targeted subsidies (for hydrogen, energy grids, R&D, technology roadmap studies etc.).
6. A dedicated approach for SMEs might be appropriate as SMEs do not have the skills/know-how to further improve their energy efficiency and/or becoming carbon neutral.
7. CAPEX and OPEX support will be necessary for breakthrough technologies, like hydrogen.
8. The Fit-for-55-Package must support the European Textile and Clothing industry in decarbonization and carbon neutrality. The EU must therefore advocate a global level playing field more than before. The primary goal must be to establish an internationally uniform, binding CO2 pricing, preferably in the form of a standard at G-7 / G-20 level.
9. EU-policy must not hinder solutions, e.g. we need reasonable state aid rules (compensating the gap between national energy or climate levies and a globally competitive energy price should not be seen as a subsidy).
10. The European Textile and Clothing industry has made use of economically viable potentials to continuously improve energy efficiency over many years and decades. The obligation to implement further measures must be taken considering investment cycles that are in line with practice. Attention must be paid to the proportionality of costs without weakening the competitive position in the EU internal market or with competitors outside the EU.

Over 400 employees work hard every day to improve the environmental performance of Radici Yarn’s site. Through teamwork and continuous improvement in energy efficiency, Radici Yarn has obtained ISO 50001 Energy Management Systems certification, which attests to the organization’s commitment to contain and progressively reduce energy consumption.

Radici Yarn, one of the companies in the RadiciGroup Advanced Textile Solutions Business Area, is engaged in the production and sale of polyamide 6 polymer, PA6 and PA66 continuous filament and staple yarn, and other synthetic fibres, including products made of recycled or bio-based materials.

All the processes - polymerization and spinning (Villa d'Ogna plant), as well as warping and draw-warping (Ardesio plant) - are run under constant monitoring with the goal of achieving maximum energy efficiency and lower consumption. Both sites are powered by two hydroelectric power plants owned by Geogreen, a RadiciGroup partner and energy supplier. The share of energy consumption from renewable sources and reduced environmental impact (natural gas) sources  is constantly increasing.

The energy issue has always been a priority for Radici Yarn, whose products serve numerous sectors, including automotive, clothing and furnishings.

"Already at the beginning of the 1990s, Radici Yarn started investing in cogeneration, the simultaneous production of electricity and steam,” pointed out Laura Ravasio, energy manager of Radici Yarn SpA. “We have recently started up an advanced trigeneration plant – a highly efficient system that produces not only electricity and steam, but also chilled water for our production processes. One of the first results recorded in 2021 was a 30% reduction in water consumption. Thus, ISO 50001 certification seemed like the next logical step to take in formalizing a long-term approach to energy.”

The ISO 50001 certification, which is voluntary and valid for a period of three years, was added to the ISO 14001 Environmental and ISO 9001 Quality Management system certifications previously achieved by Radici Yarn.

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.”
