B.I.G. Yarns unveils its new “SustainableYarns” platform, with Clerkenwell Design Week visitors the first to be invited to get on board and focus on what matters most for the design and manufacture of sustainable soft floorings.

The expert in polyamide (PA) 1 step 3 ply yarns offers a range of options for manufacturers to introduce sustainable yarns into carpet solutions and reach sustainability targets faster and more efficiently.

The Sustainable Yarns range creates opportunities to design with recycled content yarn (EqoCycle), to work with renewable resources (EqoBalance), and, following the launch of new polyamide 6 (PA6) EqoYarn at Clerkenwell Design Week, to also leverage the low-impact value chain.

New addition EqoYarn is a new low-impact PA6 carpet yarn based on the most recent innovations in polymer production, which enable yarn manufacturers to lower their carbon footprint by nearly 50% and give carpet manufacturers more options to reduce their impact.

For its EqoYarn Bulk Continuous Filament (BCF) production process, B.I.G. Yarns has selected the few best-in-class partners that have made major steps forward in terms of sustainability, and reduced their greenhouse gas emissions thanks to continuous investments in process efficiency, green energy, heat optimization and waste reduction. The result is EqoYarn with a carbon footprint of 4 kg CO2 eq/kg yarns, which is a CO2 reduction of up to 50% compared to conventional PA yarns.

EqoBalance PA6 yarns enable customers to reach an even higher CO2 reduction of up to 75%. Manufactured with polymers made from renewable resources such as organic waste from cooking oil instead of virgin or fossil feedstock, these yarns have a carbon footprint of 1.98 kg CO2 eq./ kg yarns. They help carpet manufacturers to create products with an extremely low carbon footprint.

EqoCycle PA6 yarns are fully recyclable and incorporate 75% recycled content originating from recycled and regenerated PA6 granules. With a carbon footprint of 4.64 kg CO2 eq./ kg yarns, they deliver the same high-quality performance of virgin PA6 yarn with the benefit of 37% CO2 reduction. EqoCycle yarns offer carpet manufacturers a sustainable alternative to help reduce the ecological footprint of their products and move towards a circular economy without jeopardizing the end-product quality.

In addition to the different CO2-reducing options, B.I.G. Yarns’ customers can access an unlimited colour range to elevate their designs. Its BCF technology for polyamide yarns, twisted and heat-set yarns, one-colour to multi-colour, between 650 and 15000 dTex, along with its colour studio, are available to support their creation of customised collections.

At ITMA 2023 in Milan from June 8-14 this year, Monforts is organising two free-to-attend seminars and discussions on the potential of green hydrogen as a new energy source for textile finishing, drying and related processes.

Monforts is currently leading a consortium of industrial partners and universities in the three-year WasserSTOFF project, launched in November 2022, that is exploring all aspects of this exciting and fast-rising new industrial energy option.
The target of the government-funded project is to establish to what extent hydrogen can be used in the future as an alternative heating source for textile finishing processes. This will first involve tests on laboratory equipment together with associated partners and the results will then be transferred to a stenter frame at the Monforts Advanced Technology Center (ATC).

To be considered “green”, hydrogen must be produced using a zero-carbon process that is powered by renewable energy sources such as wind or solar. Currently, the cleanest method of hydrogen production is electrolysis, using an electrically-powered electrolyzer to separate water molecules into hydrogen and oxygen. The purity of the hydrogen is also important, and impurities must be removed via a separation process.

“Despite all its advantages, there are obstacles to overcome on the way to widespread, economically-feasible green hydrogen use,” explains Monforts Textile Technologies Engineer Jonas Beisel. “Until there are widely available, reliable and economical sources of this clean power, the cost of producing it will remain prohibitive. The infrastructure is not yet there, and hydrogen also has a tendency to make steel brittle and subject to fracture, which is something that requires further investigation in both its transportation and use in industrial processing.
“Green energy’s potential as a clean fuel source is tremendous, but there is much we need to explore when considering its use in the textile finishing processes carried out globally on our industry-leading Montex stenter dryers and other machines.”

At its Advanced Technology Center (ATC) in Mönchengladbach, Monforts will be carrying out intensive tests and trials to assess the reliability of both processes and final products when different natural gas and hydrogen mixtures – up to 100% green hydrogen – are employed. The results will be closely analysed by the consortium partners because there are many parameters that at this stage remain unknown.

The aim, Beisel adds, is to both reduce CO₂ emissions and – following the rising prices and industry turbulence experienced by manufacturers over the past year or so – to further reduce a dependency on natural gas.

The three-year WasserSTOFF project is sponsored by Germany’s Federal Ministry for Economic Affairs and Climate Action, and with Monforts at the helm brings together industrial partners Pleva and NTB Nova Textil, with academic input from the Hochschule Niederrhein and the Technical University of Freiberg.

adidas has announced a new milestone in its journey towards replacing virgin polyester with recycled polyester . 96% of all polyester used in adidas products is now recycled polyester. The achievement of the ambition that adidas first set in 2017 – to replace all virgin polyester with recycled wherever possible by the end of 2024 – is on track to be achieved earlier than expected.

Since the first adidas high-performance shoe was made with recycled materials in 2015, the brand has been working towards reducing its dependency on virgin polyester. Last year it announced that in 2021, more than 90% of the polyester used in adidas products was recycled, which – if it had been virgin polyester - would have accounted for 390 thousand metric tons of CO₂e – the equivalent to the greenhouse gas emissions generated to provide power to 50 thousand homes in the US^[1].

According to Textile Exchange^[2], global recycled polyester fiber production volume increased in 2021, but still accounts for just 14.8% of all global polyester production.

Sport is about meeting challenges head-on and finding ways to overcome those – material innovation is no different. For the team at adidas, the road to 96% has been long and full of challenges. The confirmation of its polyester commitment in 2017 was a crucial step in helping to initiate a transformation across adidas and its entire supply chain. This transformation has been made possible through creating technical solutions and imagining new possibilities that previously didn’t exist.

To accompany the announcement, adidas has created a short film about its new ‘PB’, featuring star athlete Jazmin Sawyers. The film highlights the sports brand’s pride in making progress, and its determination to push further.

As the brand looks ahead to 2024 and beyond, it will continue to expand its focus beyond recycled polyester. It will be doing this through three main areas of focus: changing materials by testing and scaling new raw materials, rethinking entire processes to design products that have a circular end-of-life solution, and reducing its carbon footprint.

Ein neuartiges, ebenso umweltfreundliches wie kostensparendes Verfahren zur Herstellung von Carbonfasern aus Lignin ist an den DITF entwickelt worden. Es zeichnet sich durch hohes Energiesparpotential aus. Die Vermeidung von Lösungsmitteln und die Nutzung natürlicher Rohstoffe machen das Verfahren umweltfreundlich.

Carbonfasern werden im industriellen Maßstab gewöhnlich aus Polyacrylnitril (PAN) hergestellt. Die Stabilisierung und die Carbonisierung der Fasern geschieht dabei mit langer Verweildauer in hochtemperierten Öfen. Das erfordert viel Energie und macht die Fasern teuer. Dabei entstehen giftige Nebenprodukte, die aufwendig und energieintensiv aus dem Herstellungsprozess abgetrennt werden müssen.

Ein neuartiges, an den DITF entwickeltes Verfahren ermöglicht hohe Energieeinsparungen in all diesen Prozessschritten. Lignin ersetzt dabei das Polyacrylnitril für die Herstellung der Präkursorfasern, die in einem zweiten Prozessschritt zu Carbonfasern umgewandelt werden. Lignin als Ausgangsmaterial für die Herstellung von Carbonfasern hat bisher kaum Beachtung in der industriellen Fertigung gefunden. Lignin ist ein günstiger und in großen Mengen verfügbarer Rohstoff, der als Abfallprodukt in der Papierproduktion anfällt.

Im neuen Verfahren zur Herstellung von Ligninfasern wird zuerst Holz in seine Bestandteile Lignin und Cellulose getrennt. Ein Sulfit-Aufschluss ermöglicht die Erzeugung von Lignosulfonat, das in Wasser gelöst wird. Die wässrige Lösung von Lignin ist das Ausgangsmaterial für das Spinnen der Fasern.
Der Spinnprozess selbst erfolgt im sogenannten Trockenspinnverfahren. Dabei presst ein Extruder die Spinnmasse durch eine Düse in einen beheizten Spinnschacht. Die entstehenden Endlosfasern trocknen im Spinnschacht schnell und gleichmäßig. Das Verfahren benötigt weder Lösungsmittel noch giftige Additiven.

Die anschließenden Schritte zur Herstellung von Carbonfasern - die Stabilisierung in Heißluft und die anschließende Carbonisierung im Hochtemperaturofen - ähneln denen des üblichen Prozesses bei Verwendung von PAN als Präkursorfaser. Allerdings lassen sich die Ligninfasern im Ofen besonders schnell mit Heißluft stabilisieren und benötigen nur relativ niedrige Temperaturen in der Carbonisierung. Die Energieersparnis in diesen Prozessschritten gegenüber PAN liegt bei rund 50% und bedeutet einen echten Wettbewerbsvorteil.

Aus Wasser gesponnene Ligninfasern bieten Vorteile
Neben der umweltfreundlichen, da lösemittelfreien Herstellung, und der Energieeffizienz bietet das neue Verfahren weitere Vorteile gegenüber PAN: Lignin ist ein überaus günstiger und leicht verfügbarer Rohstoff, der aus Holz gewonnen wird. Die Verwendung eines natürlichen Rohstoffes für die Erzeugung von hochfesten Carbonfasern folgt dem Nachhaltigkeitsgedanken in der Produktion.

Der Trockenspinnprozess erlaubt hohe Spinngeschwindigkeiten. Hierdurch wird in kürzerer Zeit deutlich mehr Material produziert, als es mit PAN-Fasern möglich ist. Das ist ein weiterer Wettbewerbsvorteil, der dennoch keine Kompromisse an die Qualität der Lignin-Präkursorfasern zulässt: Diese sind äußerst homogen, haben glatte Oberflächen und keine Verklebungen. Solche strukturellen Merkmale erleichtern die Weiterverarbeitung zu Carbonfasern und letztlich auch zu Faserverbundwerkstoffen.

Zusammenfassend lässt sich sagen, dass die in dem neuen Spinnverfahren gewonnenen Präkursorfasern aus Lignin gegenüber PAN deutliche Vorteile in der Kosteneffizienz und in ihrer Umweltverträglichkeit zeigen. Die mechanischen Eigenschaften der aus ihnen hergestellten Carbonfasern sind hingegen nahezu vergleichbar – sie sind ebenso zugfest, widerstandsfähig und leicht, wie es von marktgängigen Produkten bekannt ist.

Besonders interessant dürften Carbonfasern aus Wasser gesponnenen Ligninfasern für Anwendungen in der Bau- und Automobilbranche sein, die von Kostensenkungen im Produktionsprozess in hohem Maße profitieren.
