From the Sector

International technology group ANDRITZ will present its innovative nonwovens and textile technologies at the booth of its Indian representative PRN Techtex at Techtextil India 2021 in Mumbai, India, from November 25 to 27, 2021. A special focus will lie on its technologies for air-through bonding, needlepunch, textile recycling, and processes for biodegradable wipes, like spunlace and WetlaceTM.

Air-through Bonding
Air-through-bonding lines are the preferred choice for producing nonwovens with the best quality of softness and bulk for acquisition distribution layers, top sheets, and back-sheet products. With ANDRITZ carding machines and the new flat belt oven, customers benefit from high-performance fabrics from 16 to 80 gsm, produced with bicomponent fibers. Several Chinese customers have already invested in ANDRITZ aXcess carding machines, which provide perfect web uniformity. In addition, the CETI (European Center for Innovative Textiles) in Lille, France, has installed an air-through-bonding oven from ANDRITZ.

Textil-recycling Technologies
Recently, ANDRITZ acquired Laroche SAS, a leading supplier of fiber processing technologies such as opening, blending, dosing, airlay web forming, textile waste recycling, and decortication of bast fibers. The product portfolio further complements and increases the ANDRITZ Nonwoven product range. One focus of this product range lies on complete recycling lines for post-consumer and industrial textile waste to produce fibers for re-spinning and/or nonwoven end uses.

Needlepunch Technologies
Driven by the dynamic market for durable nonwovens, ANDRITZ has developed an elliptical pre-cylinder tacker – the PA3000. With this modern machine, ANDRITZ is responding to customer demands for higher capacities and lighter products. The PA3000 is an optimized cylinder pre-needleloom, which offers greater speeds and widths and has been specially developed for lighter webs. There is no friction between the web and the rolls, and there are no issues with the visual appearance.

ANDRITZ is also focusing on its latest needling technology for producing veloured felts, mainly for applications in the automotive industry.

In addition, ANDRITZ will be presenting the next generation of its batt-forming technology, the ProWin system. ProWin is a further development of ProDynTM and ProWidTM, which have achieved a high level of acceptance on the market with around 200 systems installed. This technology improves the current weight-profiling options and increases the actual production capacity.

Production of Bio-Wipes
For many years now, ANDRITZ has offered different nonwoven processes, such as spunlace and Wetlace, with one goal in mind: reduction and elimination of plastic raw materials while maintaining the high quality of the desired product properties. The latest development in this field is the ANDRITZ neXline wetlace CP line. This is a fully engineered production line, combining the benefits of wetlaid and drylaid technologies to produce a new generation of biodegradable wipes. This process achieves high performance entirely with plastic-free raw materials. The added benefit of using a blend of fibers, like wood pulp, short-cut cellulosic fibers, viscose, cotton, hemp, bamboo, or linen, without chemical additives, results in a 100% sustainable fabric.

Indorama Ventures Public Company Limited (IVL), a global sustainable chemical company, announced its inclusion in the Dow Jones Sustainability World Index (DJSI World) and the Dow Jones Sustainability Emerging Markets Index (DJSI Emerging Markets) for the third and fifth consecutive year respectively.

Jedes Jahr unterstützt der Förderverein des Fraunhofer UMSICHT zwei Projekte mit einer Anschubfinanzierung. Die finanzielle Starthilfe ebnet den Weg, um vielversprechende Forschungsvorhaben zeitnah zu realisieren. Sein Engagement um den wissenschaftlichen Nachwuchs unterstreicht der Verein mit der Prämierung herausragender Bachelor- und Masterarbeiten. Die diesjährigen Auszeichnungen erfolgten im Rahmen der gestrigen Mitgliederversammlung, auf der evo-Vorstand Christian Basler als neuer Vorstandsvorsitzender des Fördervereins gewählt wurde.

Der UMSICHT-Förderverein ist ein wichtiger Partner des Oberhausener Forschungsinstituts und verfügt über ein großes Netzwerk aus Politik, Wirtschaft und Industrie. Neben der Verleihung des UMSICHT-Wissenschaftspreis ist die gezielte Nachwuchs- und Projektförderung ein zentrales Anliegen des mittlerweile über 30 Jahre bestehenden Vereins. So werden auf der jährlichen Mitgliederversammlung Menschen ausgezeichnet, die innovative Projekte bearbeiten und besondere Arbeit geleistet haben. In diesem Jahr erhielten die UMSICHT-Forschenden Laura Huwald und Tobias Rieger eine finanzielle Zuwendung von je 10 000 Euro für ihre Forschungsvorhaben. Die beiden Studentinnen Sonja Frerich und Hannah Brenner freuten sich über insgesamt 750 Euro Preisgeld für ihre herausragenden Bachelor- und Masterarbeiten.

Neuartige Brennstoffzellen
Laura Huwald, Abteilung Elektrochemische Energiespeicher, untersucht die »Entwicklung und Charakterisierung kohlenstoffbasierter poröser Transportlagen für Brennstoffzellen«. Dank der Substitution durch kohlenstoffbasierte Materialien kann das neuartige Zellkonzept mittels kostengünstiger und langzeitstabiler Komponenten realisiert werden. Ihre Arbeit bietet die Grundlage zur Initiierung eines Nachfolgeprojekts mit Industriebeteiligung, in dem ein Prototyp des neuartigen Brennstoffzellenkonzepts mit den am Fraunhofer UMSICHT entwickelten Bipolarplatten realisiert werden soll.

Innovative Recyclingverfahren für Kunststoffabfälle
Tobias Rieger überprüft im Projekt SubForceH2 das »Chemische Recycling von Kunststoffabfällen zur Substitution fossiler Rohstoffe in der chemischen Industrie und der Erzeugung von Wasserstoff«. Dadurch können z. B. CO2-Emissionen eingespart werden, da der in Kunststoffabfällen gebundene Kohlenstoff nicht durch konventionelle Müllverbrennung freigesetzt, sondern durch die Umsetzung zu chemischen Grundstoffen im Kreislauf gehalten wird. Als Nebenprodukt entsteht zudem Wasserstoff, welcher in zahlreichen industriellen Anwendung benötigt und zur Speicherung von Energie zunehmend an Bedeutung gewinnt.

Masterarbeit: Kunststoffe in Böden
Im Rahmen ihrer Masterarbeit »Entwicklung, Validierung und Anwendung einer Methode zur Untersuchung von Kunststoffemissionen auf landwirtschaftlichen Nutzflächen« entwickelte Hannah Brenner eine praxisorientierte Methode, mit der Bodenproben nach ihrer Entnahme auf dem Feld aufbereitet und hinsichtlich ihres Mikroplastikgehalts analysiert werden können. Ziel ist die Einschätzung der Belastung von Feldflächen durch Kunststoffemissionen und der anschließende Vergleich mit anderen Habitaten. Dadurch soll eine schnellstmögliche Reduzierung des Mikroplastikeintrags in terrestrische Ökosysteme erreicht werden.

Herausragende Bachelorarbeit
Hauptbestandteil von Sonja Frerichs Bachelorarbeit war es, die mechanische Eignung eines neuartigen, am Fraunhofer UMSICHT entwickelten Materials für den Einsatz in Brennstoffzellen zu untersuchen. Im Fokus stand die Umformbarkeit von thermoplastbasiertem Folien-BPP (BPP: Blasextrudiertes Polypropylen), um Gasverteilungsstrukturen für Wasserstoff und Sauerstoff einprägen zu können. Die Vermessung der eingeprägten Strukturen wurde unter anwendungsnahen Bedingungen durchgeführt.

In the Canopy’s 2021 Hot Button Ranking, Kelheim Fibres once again occupies a leading position: With a increase of 2.5 points in the evaluation, the Bavarian viscose speciality fibre manufacturer tied for third place out of around 40 viscose fibre manufacturers worldwide and a dark green/green shirt for the second year running. The Hot Button Report not only stands for responsible raw material sourcing - it is an overall sustainability indicator for viscose fibre producers.

Especially in the areas of transparency and procurement, the NGO Canopy, which is committed to the preservation of ancient and endangered forests, awarded Kelheim Fibres top points: Kelheim Fibres is the only EMAS-certified viscose fibre manufacturer worldwide and publishes all environmentally relevant data publicly.

Kelheim Fibres also gained points in the area of "Next Generation Solutions" - the use of alternative raw materials in fibre production. Together with the Swedish textile recycling company Renewcell, the fibre experts are planning to realise the large-scale production of high-quality viscose fibres from up to 10,000 tonnes of the 100% textile recyclate Circulose® per year.

The Swedish textile recycling company, Renewcell, has chosen AFRY as partner in order to digitalize production operations in their plants in Kristinehamn and Sundsvall, Sweden. AFRY will deliver an Industrial IT solution, containing AFRY MES and AFRY ProTAK, to manage production information and secure both high quality, as well as high overall efficiency in the production. The delivered solution will serve as a hub for all production process information.

Renewcell is a multi-award-winning textile recycling company based in Sweden. With the technology they have developed, the company has succeeded in recycling and regenerating textile fiber from old clothes to turn it back into fiber pulp. Renewcell has had a production site in Kristinehamn since 2017 and is now scaling up the production in their new production plant in Sundsvall. The new plant is expected to be operating during the first half of 2022. “Modern production and logistics require a high level of digitalization to meet the demands for, e.g., traceability, and therefore the systems and experience from AFRY will be very important to us,” says Ylva Stjernquist, Supply Chain Manager and Project Leader at Renewcell.

AFRY has a long experience in Industrial IT and will now deliver the two leading, closely integrated digital solutions for production management to Renewcell. The AFRY MES (Manufacturing Execution System) is a highly advanced digital information system that connects, monitors, and controls the complex production systems and data flows of the production processes. AFRY ProTAK is a digital tool that measures the effectiveness of a plant’s production machine performance. The system gathers information from different sources (e.g., DCS, MES, Maintenance) and combines that with the operators’ notes to calculate or present Overall Equipment Efficiency (OEE), which will lead to optimized production and increased profitability.

Together these tools will improve traceability and secure a high production efficiency by integrating data from all production systems and equipment. “We are focusing on improving sustainability within process industries, and it is therefore an honor to be part of Renewcell’s textile recycling through a full-scale digitalized solution. Our modern and competitive digital solution will definitely bring added value to these types of processes,” says David Andersson, Business Segment Manager Digitalization, AFRY Process Industries Sweden.  

AFRY MES and AFRY ProTAK will be installed to both Kristinehamn and Sundsvall plants. The installation is planned to be up and running during Q2 2022.

• Nachhaltigkeit neu gedacht

Mit seiner neuen Kollektion Core Level 1 beschreitet der Kleinostheimer Workwear-Produzent Weitblick die nächste Stufe, was das Thema Nachhaltigkeit betrifft: die für die Kernbereiche Industrie & Handwerk zugeschnittene Produktlinie überzeugt nicht nur mit der Grünen Knopf - Zertifizierung und dem Supporting Fairtrade Cotton Label, sondern setzt zudem auf den Einsatz von Repreve-Polyester aus recycelten Plastikflaschen. Im Rahmen der laufenden Zielsetzung, bei Weitblick für mehr Nachhaltigkeit und weniger Umweltschädlichkeit zu sorgen, ist die hochwertige Core Level 1 Kollektion ein wichtiger Meilenstein für eine neue, faire Zukunft.

Plastikflaschen ein zweites Leben geben
Das Recyclingpolyester steht herkömmlichen Geweben in Punkto Performance in nichts nach: sowohl bei der Langlebigkeit und Belastbarkeit als auch bei der Industriewäsche überzeugt das nachhaltige Recyclinggewebe mit höchster Punktzahl. Zur Herstellung der Repreve-Fasern werden gebrauchte PET-Flaschen geschreddert, eingeschmolzen und dann zu einem neuen Polyester-Faden verarbeitet, aus dem dann das neue Gewebe entsteht. Zu 100 % recycelt und dank der im Recyclingprozess integrierten Tracer sogar ganz transparent rückverfolgbar. Für den Kunden nachvollziehbar wird der Einsatz von Recyclingflaschen zudem über den so genannten Bottle Count: Je nach Produkt und eingesetzter Gewebemenge ist so die verarbeitete Anzahl an Flaschen pro Kleidungsstück grafisch dargestellt und auf einen Blick ersichtlich.

Einsteigerkollektion für höchste Ansprüche
Entstanden ist eine Kollektion, die nicht nur hohe Produktvielfalt bietet, sondern auch durch moderne und frische Schnittführung überzeugt. Das urbane, kontemporäre Design orientiert sich an der Outdoorbranche und vereint scheinbar mühelos höchste Anforderungen an Ästhetik und Preis. Überzeugend ist die optimale Kombinierbarkeit der Stücke untereinander, aber auch im Mix & Match mit Artikeln aus dem Core Ergänzungssortiment wie Softshell- oder Winterjacken sowie der hochwertigen Greybull 2.0 Kollektion, die sich im gleichen Farbspektrum bewegt.

Optimales Wäschemanagement
Um neben der höchsten Qualität auch die zukünftigen Anforderungen an das Industriewäschemanagement zu erfüllen, verfügen alle Kollektionsstücke über waschbare RFID Etiketten zur automatischen Identifikation. Präzision & Geschwindigkeit im Waschzyklus sind so optimal steuerbar. Gleichzeitig sind die Tags im jeweiligen Kleidungsstück dabei so verarbeitet, dass keinerlei Hautkontakt entsteht.

The Chairman of the Walter Reiners-Stiftung foundation of the VDMA Textile Machinery Association, Peter D. Dornier has awarded prizes to three successful young engineers. The award-winning works provide practical solutions on the topic of circular economy. For example, the recycling of carbon fibres, which are used to produce lightweight components for the automotive industry. Or the environmentally friendly production of yarns from crab shells. Another topic was medical applications: The processing of ultra-fine yarns into stents for aortic repair. The award ceremony took place online on 9 November as part of the Aachen-Dresden-Denkendorf International Textile Conference.  

With a creativity prize, endowed with 3,000 euros, the foundation honoured the diploma thesis of Irina Kuznik, TU Dresden. She used a creative approach to realise solutions for processing chitosan into fibre yarn.

Mr Kai-Chieh Kuo was awarded the diploma/master's thesis promotion prize of 3,500 euros. With his master's thesis, which was written at RWTH Aachen University, Mr Kuo contributes to the production of vital components used in medicine. The stents made of ultra-fine yarns are made possible by an innovative modification of the classic tube weaving process.

The Walter Reiners Foundation rewarded the doctoral thesis of Dr. Martin Hengstermann with the promotional prize in the dissertation category, endowed with 5,000 euros. The thesis deals with the production of recycled carbon fibres. These can be used to produce lightweight components for motor vehicle and aircraft construction or the wind energy sector.

New Prize Sustainability / Circular Economy
The environmental conditions of the textile industry and machine construction are changing. Topics such as climate protection and the circular economy are becoming central. From this perspective, the board of the Walter Reiners Foundation has decided to further develop the foundation's prize system.

In 2022, the foundation will for the first time offer a prize with a focus on design / sustainability. Peter D. Dornier, Chairman of the Foundation, explained: "Already in the design phase, one can set the parameters so that a textile product can be reintroduced after use into the economic cycle for a high-quality application. For example, through the appropriate use of materials and finishing. We are looking for solutions for resource-saving design, technology and manufacturing processes."   

After its launch on 20 September 2020, the RCI is proud to celebrate its first anniversary this fall. The balance sheet of the first year is impressive: starting from 11 founding members, that number increased to 30 member companies within 12 months. Numerous webinars, press releases, background information, a glossary and a comic allowed to convey the “Renewable Carbon” concept to the public. The RCI is actively working on labelling and policy analysis, and more activities will follow in the next year.

Key for this success: the topic of renewable carbon in chemicals and materials is increasingly becoming a focus of politics and industry. Larger companies will have to report their GHG emissions and also the footprint of their products as part of legislative changes surrounding the European Green Deal. In this context, indirect emissions and the carbon sources of materials will play a much more crucial role. The RCI is actively working on solutions for companies to shift from fossil to renewable carbon, which consists of the use of bio-based feedstock, CO2-based resources and recycling. In the future, reporting on GHG emissions will also include Scope 3 emissions, which are all indirect emissions that occur along the company’s value and supply chain and where the used raw materials account for a large proportion of the footprint. Here is where the carbon source of chemicals and plastics comes into play as an important contributor to the carbon footprint. Without a shift from fossil to renewable carbon feedstocks (combining bio-based, CO2-based and recycled), a sustainable future and the Paris climate targets will be almost impossible to master.

To discuss, promote and realise the shift, 30 innovative companies have already joined forces to support the transition to renewable carbon, considering both technological and economical approaches – and helping to shape the political framework accordingly.

For the second year, RCI plans to focus on a comprehensive understanding of the expected political framework conditions in Europe and across the globe, since they will determine the future of chemistry and materials more than ever. Building on this knowledge, the topic of renewable carbon could then to be systematically integrated into new political directives, which has so far not been effectively managed.

In reality, the political focus lies on the strategy of decarbonising the energy sector, a very central and Herculean task. However, it cannot be applied to the chemical and material world because carbon is usually the central building block that cannot be dispensed with. On the contrary, the demand for carbon in the chemical and materials sectors is expected to more than double by 2050. In order to meet this demand in a sustainable manner, we must move towards quitting fossil carbon. For the first time in industrial history, it is possible to decouple chemistry and materials from petrochemicals and completely cover the demand through the utilisation of biomass, CO2 and recycling.

The ITA Group, consisting of the Institute for Textile Technology of RWTH Aachen University (ITA), their research and development service provider ITA Technologietransfer GmbH (ITA GmbH) are proud to announce their new strategic positioning: in order to better respond to actual industrial demands and needs, ITA decided to install a partnership model as of January, 25 2022.

The ITA Group comprises the ITA of RWTH Aachen University, a leading research and qualification research institute with 400 employees in the areas of fibre-based high-performance materials, textile semi-finished products and their manufacturing processes and the ITA Technologietransfer GmbH, the partner of the industry in R&D, providing technology and knowledge transfer, as well as offering comprehensive solutions along the entire textile value chain.

Prof. Dr. Thomas Gries, Director of ITA, explains the new partnership model:” The impact of the Covid-19-crisis has shown once more the importance of long-term trustworthy business relationships. Therefore, we are establishing our new partnership model where we will even more closely cooperate with our actual and future industrial partners, providing them with the latest technologies and innovations from R&D side. We will initiate networking and workgroup meetings, offer access to ITA´s large machine parks and labs, carry out joint partner projects and commonly organized publicly-funded projects as well as training for partner´s employees and HR opportunities.”

Dr. Christoph Greb, Scientific Director of ITA: “We are very happy to initiate this new partnership model where science, research and industry are working shoulder to shoulder in pre-competitive projects on our future projects along the entire value-chain from the fibre to the final component in order to close a missing gap and form innovative paths forward in various industrial fields.”

During an initial session of three Innovation days in hybrid format, ITA successfully introduced in September 2021 the first industrial partner projects which will be carried out, among them “Recycling of composite battery cases”, “Recycling of composite pressure vessels”, “Natural Fibre Composites”, “Textile Structures with focus on biaxial Warp-Knitted Structures”, “Factory of the Future”, “Tapes and Hybrid Yarns”.

The next opportunity to meet with ITA is at JEC DACH in Frankfurt (November 23 and 24 2021).

The Hygiene Fibers Group of Indorama Ventures (IVL) came together at the Index Show to present an all-inclusive range of recycled and biodegradable solutions for Hygiene Fiber and Nonwoven applications.

The combination of polymers, technologies, processes and global reach supported by the Hygiene Fibers Group – one of three business segments that make up Indorama Ventures – positions it within the Hygiene industry to meet increasingly challenging market demand for innovative sustainable solutions within the hygiene sector. Across the six brands and companies that make up Hygiene Fibers Group – Auriga, Avgol, FiberVisions, Indorama Asia, Trevira and Wellman International – sustainability and supporting customers to achieve circular objectives is integral to all efforts and fundamental to the ethos of the Hygiene business segment.

At the Index Show, the Hygiene Fibers Group launched CiCLO®, a textile technology which allows polyester and other synthetic materials to biodegrade like natural materials do in wastewater treatment plant sludge, sea water and landfill conditions, reducing synthetic microfiber pollution generated during washing, and minimizing plastic accumulation in landfills caused by discarded textiles.

In line with the company’s commitment to support customers with high performance products, while also reducing the impact on the environment, several of the  Hygiene Fibers brands, including Wellman International, Trevira GMBH and Auriga, have been working closely over the last 12 months with the IAM team and the CiCLO® technology. Developments have focused on PET and rPET staple fiber and filament sustainable solutions for applications where recycling is particularly challenging, such as Hygiene, Home Textiles and Automotive applications.

Strengthening the profile of biodegradable offerings within the Hygiene Fibers Group’s sustainability portfolio, Trevira introduced a new range of bicomponent fibres based on PLA and PBS (polybutylene succinate) at the Index show. Both biopolymers offer an exceptional technological opportunity in terms of environmental care and sustainability, while delivering optimum performance. Equally to PLA, PBS is recyclable and up to 100% biodegradable under industrial conditions.

Efforts towards supporting customers to achieve circular objectives are a priority within the Hygiene Fibers Group. This is reflected in the recycled fibers expertise deployed across the segment. Four Hygiene Fibers Group brands, IVL Asia, Auriga, Trevira and Wellman International offer an extensive range of 100% recycled, accredited PET fibers, across a multitude of fiber and nonwovens applications.

The development and evolution of sustainable technologies is central to activity across IVL’s Hygiene Fibers Group, with particular focus on sustainable polyolefin solutions. FiberVisions and ES-FIBERVISIONS, leading Polyolefin mono and bico fiber brands and sister company Avgol, have partnered with UK-based Polymateria to commercially harness the innovative ‘biotransformation’ technology pioneered by Polymateria. The patented technology alters the properties of polyolefins to make them biodegradable in a natural process.  Other polyolefin sustainable innovations within the Hygiene Fibers Group were featured at Index include biosurfactant and biocolourant developments being undertaken by the Avgol team with FiberVisons progressing sustainable design solutions, including lightweight, high performance, reduced carbon solutions.
