Aachen researchers develop sustainable artificial turf

The current European Football Championships 2024 in Germany will be played on natural turf, which is very costly to maintain, does not tolerate high frequency of use and has a limited service life of only 6 months in some cases. Artificial turf is easier to maintain and correspondingly popular. In Germany, there are estimated to be more than 5,000 artificial turf pitches and as many as 25,500 across the EU. The drawback: the enormous annual emission of microplastics in the form of infill material, the high CO2 impact and the not environmentally friendly disposal. Researchers in Aachen presented a sustainable alternative: BioTurf is a new artificial turf system made from bio-based polymers that no longer requires polymer infill material!

The current European Football Championships 2024 in Germany will be played on natural turf, which is very costly to maintain, does not tolerate high frequency of use and has a limited service life of only 6 months in some cases. Artificial turf is easier to maintain and correspondingly popular. In Germany, there are estimated to be more than 5,000 artificial turf pitches and as many as 25,500 across the EU. The drawback: the enormous annual emission of microplastics in the form of infill material, the high CO2 impact and the not environmentally friendly disposal. Researchers in Aachen presented a sustainable alternative: BioTurf is a new artificial turf system made from bio-based polymers that no longer requires polymer infill material!

"Every year, around 500 kilograms of plastic granules are produced per artificial turf pitch, which have to be refilled as infill. This also corresponds to the amount that potentially enters the environment as microplastics per sports pitch," explains Dr Claudia Post from TFI. With an estimated 25,000 artificial turf pitches in the EU, artificial turf in Europe alone produces 12,750 tonnes of microplastics that end up in the environment every year! The TFI - Institut für Bodensysteme an der RWTH Aachen e.V., Institute for Research, Testing and Certification in Europe for Indoor Building Products, has developed the innovative artificial turf system together with the ITA (Institute for Textile Technology at RWTH Aachen University) and in collaboration with the company Morton Extrusionstechnik (MET), a specialist in artificial turf fibres.

"New artificial turf pitches will be phased out by 2031 at the latest due to the ban on plastic granules. Even now, artificial turf pitches with infill material are no longer being subsidised," says Dr Claudia Post. For grassroots sports, clubs, cities and local authorities, converting their existing artificial turf pitches will be a mammoth task in the coming years, as artificial turf pitches have to be replaced every 10-15 years. With BioTurf, an environmentally friendly alternative is now available! The surface can be played on like any other, whether running, passing or kicking. Short, heavily crimped blades support longer blades and this simple approach increases playing comfort. BioTurf fulfils all quality requirements and standards for the highest footballing demands.

"BioTurf is an innovative, holistic solution," emphasises Dirk Hanuschik from TFI. "We use rapeseed oil and agricultural waste that does not compete with food production. BioTurf is also almost completely recyclable".
This is in stark contrast to conventional artificial turf, which can currently only be thermally utilised, i.e. burned to generate heat.

As BioTurf does not require the traditional latex process at all, the energy-intensive drying process can be dispensed with, which has a positive effect on the price. Latex is also difficult to recycle. In contrast, BioTurf uses the new thermobonding technology. Here, the thermoplastic pile yarns are thermally fused to the backing. Further development steps still need to be taken in the endeavour to develop a 100% mono-material artificial turf, as a few percent polypropylene still needs to be processed in the backing in addition to the polyethylene fibre material in order to protect it during thermobonding. However, this does not hinder its recyclability.

The participants had received basic information in advance through the 45 training videos and training sessions of the free and public Smart, Digital and Green Skills Academy at https://addtex.eu.

The hackathon at the Italian university PIN (Polo Universitario Città di Prato) was organised and held together with the technical textiles department of the Industrieverband Veredlung - Garne - Gewebe - Technische Textilien e.V. (IVGT). Eight teams competed to develop innovative, sustainable ideas in just a few hours for the German family business Schmitz Textiles GmbH & Co. KG, Emsdetten. Schmitz Textiles, an expert in complete textile solutions for indoor and outdoor use for over 100 years, plans to offer exclusively sustainable products in the medium term and is looking for solutions to continuously increase the existing recycled share of yarns to 100 per cent.

Stefan Schmidt from IVGT presented the challenge via Teams Conference: "We are looking for a new business model for textile recycling at awning manufacturer Schmitz-Textiles in order to increase the existing proportion of recycled yarns and go beyond the exclusive use of recycled PET bottles. Schmitz Textiles has had an awning fabric made from 100% recycled polyester in its range since the end of 2023. The medium-term goal is to switch the entire range of awning fabrics to 100% recycled yarns. The company is looking for suitable solutions to achieve this.

In small teams, the 30 students specialising in eco-design, textiles/sales and textiles/technology developed proposals and presented them in five-minute online pitches. Ralf Bosse for Schmitz Textiles and Iris Schlomski for the IVGT acted as the jury and assessed the individual presentations in the categories of degree of innovation, presentation, industrial application potential and potential for commercial success. Each idea presented and each presentation scored more or less points in the individual categories. In the end, the points scored were added up to determine the winning team, which can further develop its idea together with the company. For Schmitz Textiles, these are Eleonora Boccherini, Ilaria Ioja, Giorgio Gacci and Marianna Butera.

Saralon and STFI: Stretchable silver inks for e-textiles

With the next generation of soft and stretchable electronics, reproducible and stretchable conductive inks are playing an increasingly important role in areas such as smart textiles, medical textiles or wearables. Saralon produces a range of stretchable conductive inks including Saral StretchSilver 500 for e-textile applications.

While electronic applications integrated into textiles gain popularity, printed stretchable conductive inks emerge as a transformative alternative for the complicated approach of weaving conductive yarns and fibres.

Just like choosing the right fabric and additives is vital for smart textile development, selecting the right conductive ink matters too. There are challenges to consider, such as conductivity, ink penetration into the fabric, changes in physical properties most importantly stretchability, printing process controllability, and reproducibility. That's why research and analysis are essential when deciding on the best conductive ink for a project.

Together with the Saxon Textile Research Institute e.V. (STFI) Saralon conducted some performance tests benchmarking our Saral StretchSilver Ink against some competitor product.

Results:
Conductivity:

Saral StretchSilver 500 consistently demonstrated superior conductivity, regardless of line width.

Fluctuations at lower widths:
Both inks exhibited fluctuations at narrower printed lines, but the Alternative Ink displayed significantly higher variations.

Reproducibility Insights:
Saral StretchSilver 500 maintained stable resistance at 2mm and beyond, while the Alternative Ink noticeably struggled.

Elongation behaviour:
Saral StretchSilver 500 harmoniously coexists with the textile. Its application has minimal impact on the fabric's stretching properties, ensuring stability. The Alternative Ink, on the other hand, leads to significant changes in textile’s elongation properties. With this ink, stretching demands considerably higher forces.

Molotowcocktailschutzanzug – textiler Schutzanzug für Polizeieinsatzkräfte zum Schutz vor Molotowcocktails
Spezialeinsatzkräfte sind auf Schutzkleidung angewiesen, die vor vielfältigen Gefahren schützt. Meist schränkt eine höhere Schutzwirkung den Tragekomfort ein. Forscher des STFI und des ITA Aachen haben daher gemeinsam ein hitzebeständiges Gewebe entwickelt, das vor Angriffen mit Molotowcocktails schützt und dabei gleichzeitig einen hohen Tragekomfort gewährt. Molotowcocktails können schwerwiegende Verletzungen hervorrufen, die es zu verhindern gilt. Das Verletzungspotential hängt insbesondere mit der extrem hohen Verbrennungstemperatur von 800 °C – 1.700 °C zusammen, aber auch der starken adhäsiven Wirkung der Brandsätze. Die entwickelte Schutzkleidung zeichnet sich durch eine optimierte Faserzusammensetzung sowie durch eine spezielle Garn- und Gewebekonstruktion aus. Dar-über hinaus wurde die Funktionalisierung des Gewebes angepasst.

Holz/Textil-Faltwerke
Im abgeschlossenen Projekt wurden Holz-Textil-Faltwerken (HTF) entwickelt, die temporär zum Zweck des Schallschutzes, Sichtschutzes oder der räumlichen Abgrenzung aufstellbar sind. Unter Nutzung der Origami-Mathematik wurden mehrschichtige Holz-Textil-Verbunde entwickelt. Das Textil dient als zweidimensionales Scharnier der fertigen Konstruktion. Durch den Verbund aus biegeschlaffen textilen Materialien mit biegesteifen Holzelementen sind Faltbewegungen möglich, die eine selbsttragende Struktur entstehen lassen. Die HTF zeichnen sich durch kleines Packvolumen und Leichtbauweise aus. Gezeigt wird ein Tischmodell des Demonstrators.

Graviola
In der Naturmedizin werden die Blätter des tropischen Graviola-Baumes (Annona muricata) zur Verbesserung des Wohlbefindens und zur Behandlung zahlreicher Krankheiten eingesetzt. Die Wirkung der Graviolapflanze ist hauptsächlich auf die enthaltenen aktiven Wirkstoffe der Acetogenine zurückzuführen. Ziel des Projektes GRAVIOLA war die Entwicklung neuartig funktionalisierter Textilien, die mit Wirkstoffen der Graviolapflanze ausgerüstet sind. Gezeigt werden auf dem internationalen Pavillon des Innovationstag Mittelstand mit Graviola ausgerüstete Textilmuster auf Basis von Wirkstoffverkapselungen und Graviolaextrakten.

INTAKE – Entwicklung und Erprobung intelligenter Einbringungstechnologie für Datenkerne in der Wäschekonfektionierung
Im Projekt INTAKE haben sich aktuell sechs Forschungspartner das Ziel gesetzt, ein KI-gesteuertes Verfahren zu entwickeln, das RFID-Antennenfäden und -Chips während des Konfektionsprozesses in die Wäsche einbringt und so die Notwendigkeit des nachträglichen Patchens eliminiert. Die Wäsche selbst wird so zu einem individuell funktionalisierten RFID-Transponder gemacht. Gezeigt wird Flachwäsche wie z.B. Bettlaken oder Kopfkissen mit integrierter kleindimensionaler RFID-Fadentechnologie inkl. Datenkern und Textilantenne für eine gesteuerte Einbringung per KI und zukünftige Leasing-Szenarien

Teijin Frontier: Breathable, UV-blocking polyester material

Teijin Frontier Co., Ltd., the Teijin Group’s fibers and products converting company, announced the development of a new, multifunctional and comfortable polyester material that combines high breathability and UV protection. This new product reproduces the structure of a traditional Japanese "Sudare" blind (bamboo blind), which allows breezes to pass through while blocking out sunlight.

As extremely high summer temperatures become increasingly common, Teijin Frontier developed this new polyester to meet market demands for materials with enhanced heat protection functions. Heat protection encompasses breathability, UV resistance and anti-stickiness. However, until now, breathability – achieved by gaps between fibers – and UV protection were thought to be mutually exclusive.

To solve this dilemma, the company created a structure with slit-shaped, highly breathable areas in either the warp or weft direction of the fabric. These three-dimensional gaps, similar to those in a bamboo blind, allow the material to deliver both excellent breathability and high UV blocking performance of 85 percent or more. The structure allows air permeability of 50㎤/㎠・s or more.

This new product also offers sustainability benefits through the incorporation of recycled polyester in part. Its structure and elastic fibers provide stretch performance, while an uneven surface caused by differences in thread shrinkage and its structure avoid stickiness. Moreover, to achieve the combination of functions, Teijin Frontier also adopt special high-shrinkage technology and dying finishing technology. This material offers potential for use in both fashion and casual clothing.

Teijin Frontier will begin promoting this product for the 2025 spring and summer fashion and casual clothing collections in Japan, aiming for sales of 250,000 meters in fiscal 2024 and 750,000 meters in fiscal 2027.

First technical coloured flax fibre replacing carbon fibre?

British technology company Hypetex has been awarded a significant grant from Innovate UK to develop the world’s first technical coloured flax fibre, which will have applications in the sustainable manufacturing of cars, boats and other products that are usually made with carbon fibre.

Called FlaxTex the material is strong, lightweight and 100 per cent biodegradable, having a net positive carbon footprint at point of manufacturing. It can be colourised whilst enhancing its performance properties, with the process adding some important manufacturing attributes compared to standard flax fibre.

As such, FlaxTex’s mechanical properties represent the closest sustainable substitute for robust and lightweight materials like glass fibre and carbon fibre in composite structures.  

The performance of standard flax fibre is often hindered by its high moisture absorption, resulting in reduced structural integrity when used in composite construction. In addition, the natural brown colour of flax has been deemed unappealing for product use.

The performance of standard flax fibre is often hindered by its high moisture absorption, resulting in reduced structural integrity when used in composite construction. In addition, the natural brown colour of flax has been deemed unappealing for product use.

Flaxtex solves these issues by removing moisture through the colouring process and sealing the fibres, which waterproofs them and enabling their core mechanical properties. Hypetex’s patented nano-pigment technology changes the colour adding an aesthetic quality to the material.  

This colouring process is set to transform industrial design possibilities of Flax natural fibres by enhancing the strength and performance while simultaneously reducing post-processing requirements and total energy usage. This also aligns with Hypetex's commitment to supporting the green transition and helping manufacturers meet government expectations on the path to UK Net Zero targets and the European Green Deal.

Over the course of a 12-month industrial research project, Hypetex will further optimize its resin systems and processes, expanding the use of FlaxTex across various markets.  

FlaxTex has a range of industry uses, including on construction, automotive, sports equipment and furniture products.

Digital Textile Micro Factory: on-demand and virtual products – on the path towards sustainable production
In cooperation with 12 partners from industry and research the DITF will demonstrate a Digital Textile Micro Factory live at drupa and, hence, a fully connected, integrated process chain from design to finished product. This will present new possibilities for digitalisation and direct customer involvement, for instance in the form of 3D apparel simulations complete with links to design networks for creative input. Digital workflows and virtual products are integrated directly in the manufacturing process. As a special highlight for all trade visitors the technology partners of this Micro Factory will demonstrate an automated on-demand production, textile printing, cutting and sorting – without any manual interaction. Such decentralised and digitally connected design and production chains will enable the textile industry to respond to customers’ requests and trends in a more targeted manner in future. This means, touchpoint textile 2024 technologically points the way to a future without shelf-warmers. In addition, the carbon footprint for the complete process from virtual development to finished product will be modelled and presented at the trade fair.  

2024 will see the design competition “drupa – textile design talents” being held for the first time. This was conceived of by the DITF and will be implemented by the partner Mitwill. This provides up-coming textile designers and newcomers with a unique opportunity to introduce their ideas and visions to a professional audience.

Broad industry support
A project as comprehensive as the Micro Factory requires many strong partners. The companies “on board” here include: Assyst/Germany (3D simulation for digital apparel twins), Mitwill Textiles Europe/France (creative design network), D.G.I. Digital Graphics Incorporation/South Korea, Multi-Plot Europe/Germany (large-format textile printing), LEONHARD KURZ Stiftung/Germany, Zünd/Switzerland (digital cutting), robotfactory/Denmark, Asco/The Netherlands (presenting an innovative buffer solution between digital printing and cutting, automated sorting of cut parts from the cutter by robotfactory) as well as Brother/Japan (for small-format textile printing and bonding technology). Vaude and berger textiles will be sponsoring the touchpoint. Another key partner is the Albstadt-Sigmaringen University that is supporting the project as a conceptual sponsor and which has set itself the clear mission to incorporate these new topics into its curriculum. This means the staff of the future will be geared up to the new challenges ahead.

Another partner of touchpoint textile is the European Specialist Printing Manufacturers Association (ESMA), which is responsible for the lecture programme. ESMA represents industrial, functional and specialist printing and acts as an organiser of educational events in the field of textile printing. At drupa speakers from research, development, and industry will address issues related to printing and finishing techniques, workflows, market developments and sustainability, to name but a few. The focus will also be on trends and applications that unlock ever new potential through the interplay of digital printing and textile printing substrates. The lectures are divided into the categories Research, Finishing, Print Systems & Hardware, Substrates, Inks & Chemistry and Software & Electronics. Assyst, for example, will deliver talks on the virtual development of apparel as well as the research project ECOShoring, which is funded by the “Deutsche Bundesstiftung Umwelt” – DBU (German Federal Environmental Foundation) and focuses on personalised and on-demand sustainable manufacturing. Other speakers represent Adobe, Balta Group, Barbieri Electronic, Brother, Centexbel, CST, DITF, Fujifilm Speciality Ink Systems, HS Albsig, Kornit Digital, Meteor Inkjet, Mimaki, Mitwill, Multiplot, Print-Rite, RWTH Aachen, Seiko Instruments, Tiger Coatings, Xaar, Zünd and the list is updated on regular basis.

Graywater treatment with 3D textiles

The demand for water in Germany is increasing and used water is not being utilized sufficiently. Graywater in particular, i.e. wastewater from showers, bathtubs and washbasins, offers great potential for further use. It can be brought to service water quality on site and reused for flushing toilets or watering gardens, for example. Thanks to flexible 3D textiles, it can even be used in almost any building to save space.

Around 50 to 80 percent of all domestic wastewater is graywater. Until now, large containers and tanks have been needed to reprocess it and return it to the cycle, taking up a lot of space in the building. The German Institutes of Textile and Fiber Research Denkendorf (DITF) and their project partner ARIS have developed a biological, textile-based system.

Until now, large containers and tanks have been needed to reprocess it and return it to the cycle, taking up a lot of space in the building. The German Institutes of Textile and Fiber Research Denkendorf (DITF) and their project partner ARIS have developed a biological, textile-based system.

It is based on a 3D spacer fabric made of highly durable polypropylene. Its advantage is that it can be installed flat and is therefore extremely space-saving. Thanks to its special system geometry, it can be installed in places that would otherwise remain unused - for example in a new building under the floor of an underground garage, on a flat roof or in the garden. It can be modularly adapted to the water requirements and structural conditions in the respective buildings. "Even vertical solutions on facades are conceivable," explains DITF scientist Jamal Sarsour. This means that the graywater treatment system could be used in densely built-up cities in particular.

The system developed by the project partners requires little maintenance and is therefore particularly cost-effective. Compared to previous solutions, it is characterized by a long lifespan. It therefore contributes to sustainable water use and makes a valuable contribution to the circular economy.

ARIS plans to launch the new textile-based graywater treatment system on the market in 2024.

The project will be presented on June 13, 2024 at the SME Innovation Day of the Federal Ministry for Economic Affairs and Climate Protection in Berlin.

The research project with the number 16KN080829 of AiF Projekt GmbH, Berlin, was funded by the Federal Ministry of Economics and Climate Protection as part of the Central Innovation Program for SMEs (ZIM) on the basis of a resolution of the German Bundestag.

Gebr. Otto: Kreislaufwirtschaft zentrales Thema auf der Techtextil

„Kreislaufwirtschaft war Gegenstand der meisten Gespräche“, sagt Andreas Merkel, Geschäftsführer von Gebr. Otto. „Wir widmen uns diesem Thema speziell in Zusammenarbeit mit dem Recycling-Atelier ITA Augsburg. In einem Projekt arbeiten wir an der Entwicklung eines Baumwollgarns, das zu 50 Prozent aus Post-Consumer-Recycling-Baumwolle, kurz PCR-Baumwolle besteht.“ Überzeugend ist der ökologische Nutzen: Im Vergleich zu einem Kilo neuer Baumwolle erfordert ein Ringgarn mit 50 Prozent PCR-Anteil einen Bruchteil des Wassers und der Energie, die für neue Rohware nötig wäre.
Einfach ist das Verarbeiten von recycelten Fasern nicht, denn diese weisen ganz andere Eigenschaften auf als Virgin-Baumwolle: Die recycelten Fasern sind deutlich kürzer, sie haben eine andere Oberflächenstruktur und dadurch andere Haft- und Gleiteigenschaften. Eine Herausforderung ist, dem Vorgarn die richtige Drehung mitzugeben, so dass in der Ringspinnerei keine Fehlverzüge entstehen.
„An der technischen Umsetzung für die Spinnerei und die Spinnereivorbereitung arbeiten wir derzeit“, erklärt Andreas Merkel. „Für zwei Garnstärken haben wir schon erfreulich gute Ergebnisse erzielt.“

Von Haus aus nachhaltig
Dem Thema Recycling widmet sich Gebr. Otto bereits seit langem – bisher im Bereich pre-consumer waste. Die Otto-Garninnovation recot2 besteht zu 25 Prozent recycelter und zu 75 Prozent aus GOTS-zertifizierter Virgin-Bio-Baumwolle. Das spart auf ein Kilogramm recot2-Textilien rechnerisch rund 5.000 Liter Wasser. Beim wiederverwerteten Material handelt es sich bei recot2 um Webkanten und Spulenreste.  Auf den Markt gebracht hat Gebr. Otto dieses Garn schon vor 15 Jahren. „Im Markt aktiv nachgefragt wird das Recycling-Garn allerdings erst seit einigen Jahren“, sagt Andreas Merkel. Mittlerweile kommt es bei Wäsche- und Bekleidungsherstellern zum Einsatz und verhält sich, so die Kunden, nicht anders als ein Baumwollgarn aus neuen Fasern.

Innovationspartnerschaft mit Kelheim
Gemeinsam mit dem bayrischen Faserspezialisten Kelheim Fibres hat Gebr. Otto ein Konzept für nachhaltige wie leistungsfähige Periodenunterwäsche entwickelt. Dabei kommen biobasierte Materialien zum Einsatz, die sich durch überzeugende Performancewerte auszeichnen. Die eingesetzten verschiedenen Viskosespezialfasern stammen von Kelheim. In der jeweils passenden Zusammensetzung verspinnt sie Gebr. Otto. „Aufgrund der Anforderungen und der Testergebnisse, die Kelheim für die verschiedenen Schichten der Panty ermittelt hat, entwickeln wir unsere Garnmischungen“, erklärt Andreas Merkel, Geschäftsführer von Gebr. Otto. „Auf kurzfristige Anforderungen, auch für Spezialanfragen von Wäsche-Brands, also den Verwendern, können wir binnen kurzer Zeit die gewünschten Garne liefern.“   

Baumwolle-Hanf Mischung
Neu ist eine Mischung aus Bio-Baumwolle und nativem Hanf aus Deutschland. „An sich gibt es Fasern aus Hanf schon lange“, erklärt Andreas Merkel. „Die Faser ist etwas gröber und ‚störrischer‘ als Baumwolle.“ Mit einem neuen Aufschlussverfahren – vorgenommen durch einen regionalen Partner – kann Otto den Hanf nun mit langstapeliger Bio-Baumwolle verspinnen. „Wir konnten gute Garnwerte erreichen und haben auf der Techtextil verschiedene Anfragen zur Bemusterung bekommen.“ Eingesetzt wird die neue Hanf-Baumwoll-Mischung für Gestricke genauso wie Gewebe oder im Sockenbereich.  

„Wir hatten über alle Messetage eine sehr hohe Frequenz an Besuchern auf unserem Stand“, sagt Andreas Merkel. „Wir konnten direkt vor Ort einige Abschlüsse erzielen. Außerdem haben wir Aufträge für Bemusterungen und Anfragen für Projekte mit nach Hause genommen“, fasst Merkel zusammen. „Das darf allerdings über die schwierige Marktlage nicht hinwegtäuschen: Wir erleben eine Zeit hoher Kaufzurückhaltung, sehen Insolvenzen von Marktbegleitern und Partnern. Auch wir von Gebr. Otto verzeichnen im Vergleich zum Vorjahr einen Umsatz- und Mengenrückgang. Wir sind allerdings auf einem sehr hohen Niveau gestartet, was bedeutet, dass wir auch heute profitabel arbeiten können.“
