From the Sector

Prof. Dr. -Ing. Jörg Müssig und Vincent Röhl von der Hochschule Bremen trugen mit einem Kapitel über Wollfaserverbundwerkstoffe im Spritzguss und im 3-D-Druck zum Buch "Wool Fiber Reinforced Polymer Composites" bei.

Pflanzliche Naturfasern gewinnen als Verstärkungselemente in Verbundwerkstoffen zunehmend an Bedeutung. Wolle hingegen ist in derartigen Werkstoffen bisher eher selten zu finden, hat allerdings ein überaus spannendes Potenzial.

Das aktuell erschienene Buch zu wollfaserverstärkten Polymerverbundwerkstoffen stellt eine eingehende und praktische Analyse von Verbundwerkstoffen auf der Basis von Wolle dar und deckt alle Bereiche von der Morphologie der Wollfaser bis zu den industriellen Anwendungen von Wollfaserverbundwerkstoffen ab. Untersucht werden unterschiedlichste Formen von Wollfaserverbundwerkstoffen, Beschreibungen umfassen Morphologie, Struktur und Eigenschaften von Wolle, Methoden zur chemischen Modifizierung von Wolle, verschiedene Formen von Woll-Polymer-Verbundwerkstoffen und weitere neue Anwendungen.

Unter dem Titel „Wool fiber-reinforced thermoplastic polymers for injection molding and 3D-printing“ bekommen die Leser:innen einen Überblick vom Aufbau natürlicher keratin-basierter Strukturen, deren Eigenschaften bis hin zur Verwendung von Wolle in Verbundwerkstoffen. Neben Anwendungsmöglichkeiten im 3-D-Druck gehen die Autoren auch auf das bionische Potenzial keratin-basierter Strukturen ein. Vor dem Hintergrund der Diskussionen über den unerwünschten Eintrag von Kunststoffen in Gewässer und Böden sehen Vincent Röhl und Jörg Müssig einen besonderen Vorteil von Wollfasern zur Verstärkung von abbaubaren Kunststoffen. Ihre aktuellen Forschungen zeigen, dass wollfaserverstärkte, biobasierte Kunststoffe sich sehr schnell im Boden abbauen und von Bodenorganismen verstoffwechselt werden können.

Monforts will highlight its technologies for special technical textile applications at this year’s ITMA ASIA + CITME which takes place at the National Exhibition and Convention Center in Shanghai, China, from November 20-24.

One of Monforts' developments is the Montex 8500 XXL stenter system for the production of technical fabrics in widths of up to 6.8 metres. Among the products made on this system are treated nonwovens for the geotextiles and filter media markets, tarpaulins, advertising banners, black-out curtains, membranes and many more.

On Montex©Coat coating lines, meanwhile, the possibilities range from the single-sided application of finishing agents for outdoor clothing and adding functionality to home textiles, to the creation of materials for sophisticated lightweight construction and automotive and aerospace components.

“Many more applications are possible, such as the overdyeing of denim, the creation of double-face coated materials, fabrics awnings, tents and medical drapes and the pre-treatment of substrates for digital printing”, explains Gunnar Meyer, Monforts area sales manager for China. “A range of different doctor blades and their combinations can be supplied to meet individual requirements, including air knife, roller knife, foam, screen and magnetic roller coating. The latter option is recommended for lines with working widths of over 2.4 metres.”

In addition, Monforts can provide the necessary explosion-proof ranges for solvent-based coatings and high temperature processes up to 320°C, such as the PTFE coating of nonwoven filter material. These lines are equipped with special burners, stenter chains, and insulation.

Das Fluorcarbon PFHxA soll durch sehr niedrige Grenzwerte reguliert werden. Die Produktion technischer Textilien für Umweltschutz, Medizin, Schutzbekleidung und Bau sieht dadurch viele Anwendungen in Frage gestellt.

Schusssichere Westen für Polizei und Militär, Schnittschutzhosen für Forstarbeiten, Spezialtextilien für Brennstoffzellen und Elektroisolation, Erosionsschutz im Tiefbau, ressourceneffizienter Leichtbau, Klima- und Sonnenschutzausstattung, flammgeschützte Auskleidungen von Transportmitteln, Wundpflaster und Verbandsmaterialien – die Produzenten von technischen Textilien sind Hidden Champions. Die deutsche Textilindustrie hat sich weltweit eine Vorreiterstellung bei den komplexen Lösungen erarbeitet und sieht jetzt zahlreiche Anwendungen durch das EU-Chemikalienrecht in Frage gestellt.
 
Grund dafür ist, dass der Stoff PFHxA mit einem extrem niedrigen Grenzwert belegt werden soll. Der Stoff findet sich aufgrund seiner thermischen und chemischen Stabilität in einer Vielzahl von Anwendungen und ist in der Textilindustrie in eingesetzten Hilfsmitteln zu finden. Auf einem fertigen Produkt ist PFHxA in nur sehr geringen Spuren zu finden – der Stoff selbst ist, nachgewiesen durch wissenschaftliche Studien, toxikologisch nicht bedenklich. Erst 2017 war PFHxA als Ersatzstoff in der PFOA-Regulierung ausgewiesen worden, zahlreiche Wertschöpfungsketten wurden umgestellt. Jetzt steht der Stoff selbst vor starken Regulierungen – einen Ersatzstoff gibt es nicht.

Um dies zu verhindern, macht die Textilindustrie einen Lösungsvorschlag: eine Ausnahme für technische Textilien gemäß DIN EN ISO 14419/Ölnote 3 (Mindestanforderung) verbunden mit einer Berichterstattung über Einsatz, Substitution und Minderung von PFHxA.

Südwesttextil, der als Verband zahlreiche Hersteller technischer Textilien in Baden-Württemberg. vertritt, sieht in der geplanten Grenzwerteinführung für PFHxA faktisch ein Anwendungsverbot. Das bedeute, dass viele technische Textilien am Standort Deutschland nicht mehr produziert werden können.

Due to the continued good business development, especially in the Carbon Fibers Business Unit, SGL Carbon SE is increasing its Group sales and earnings guidance for the current fiscal year and now expects Group sales of approximately €1.2 billion (previously: approximately €1.1 billion). The company expects to achieve adjusted EBITDA (EBITDA pre = earnings before interest, taxes, depreciation and amortization before one-off effects and non-recurring items) of €170 - €190 million (previously: €130 - €150 million) in 2022.

Based on lower prices for acrylonitrile as main raw material of the Business Unit Carbon Fibers as well as higher than expected customer demand for acrylic and carbon fibers combined with consistently good production capacity utilization and capability, the management of SGL Carbon SE assumes an improved earnings development of this Business Unit.

SGL Carbon assumes that the factors mentioned will continue at least until the end of the year and that the earnings situation of the Business Unit Carbon Fibers will exceed previous expectations. Combined with the continued good business development of the other three Business Units (Graphite Solutions, Process Technology and Composite Solutions), an improvement in the sales and earnings situation at Group level is expected.

In line with the forecast increase for adjusted EBITDA (EBITDA pre) to between €170 and €190 million (previously: €130 - €150 million), the company is forecasting adjusted EBIT (earnings before interest and taxes and before one-off effects and non-recurring items) of between €110 and €130 million (previously: €70 - €90 million). The forecast for return on capital employed (ROCE) of originally 7% - 9% has been raised to 10% to 12% corresponding to the development of earnings. The expectations for free cash flow (significantly below previous year's level of €111.5 million) remain unaffected by the expected improvement in sales and earnings.

The updated forecast for fiscal 2022 has been prepared on the basis of the currently prevailing market environment and assumes no deterioration in the general conditions, in particular due to the war in Ukraine and its consequences for the global economy.
 
The definition of key figures used in this release is aligned to the Annual Report 2021. There were no changes in the scope of consolidation or accounting methods compared with the previous guidance.

Ein Garn zu spinnen, ein Gewebe oder Gestrick zu produzieren, anschließend zu veredeln und zu einem fertigen Textil mit breiten Anwendungsfeldern zu konfektionieren, benötigt viel Know-how. Passend dazu bieten Textil- und Bekleidungsunternehmen Ausbildungsberufe an, deren Anwendungsfelder ganz nach dem Motto „Textil kann viel“ nicht vielfältiger sein könnten. Produktionsmechaniker*innen Textil können ihr Geschick im Umgang mit Maschinen unter Beweis stellen; Produktveredler*innen Textil sind direkt in das Veredeln und Färben eingebunden; Textil- und Modeschneider*innen verwandeln Stoffe in Kleidungsstücke und andere Produkte. Auch Ausbildungen im kaufmännischen Bereich, in Logistik oder IT hat die Industrie zu bieten.

„Wir möchten noch mehr junge Menschen für eine Ausbildung in unserer spannenden und innovativen Branche begeistern. Deshalb investiert Südwesttextil mit dem Bau des Texoversums auf dem Campus der Hochschule Reutlingen in die Zukunft der Ausbildung. Das Texoversum ist einer der Orte, an dem die textile Aus- und Weiterbildung ihre Innovation und Attraktivität aufzeigt und vorantreibt“, so Edina Brenner, Hauptgeschäftsführerin des Wirtschafts- und Arbeitgeberver-bands Südwesttextil.

In den Nachwuchs zu investieren hat beim Verband der Südwestdeutschen Textil- und Bekleidungsindustrie e.V. Südwesttextil Tradition: Seit 1980 sind in der Gatex, der überbetrieblichen Aus- und Weiterbildungsstätte der Branche, mehr als 1.000 Menschen erfolgreich qualifiziert worden. Auszubildenden ermöglicht die Gatex das Lernen entlang der textilen Kette, sodass sie im Anschluss im Betrieb auch vor- oder nachgelagerte Stufen der Produktion mitdenken können.
 
Mit dem Umzug der Gatex von Bad Säckingen nach Reutlingen setzt Südwesttextil auf einen zentralen Ort und die Verknüpfung mit dem Studienangebot der Hochschule. Schon jetzt schnuppern die Auszubildenden Campusluft, denn das überbetriebliche Ausbildungsjahr beginnt direkt in Reutlingen. Das Texoversum wird im Frühsommer des nächsten Jahres eröffnet und bietet dem textilen Nachwuchs Raum fürs Lernen, Ausprobieren und Vernetzen. Denn in den 3.000 Quadratmetern des innovativ gebauten Gebäudes befinden sich neben Schulungsräumen auch Werkstätten, Labore und Think-Tank-Flächen.

Freudenberg Performance Materials is introducing Freudenberg Friction Inserts to trade visitors at WindEnergy, the leading trade fair for the international wind energy industry. Freudenberg Friction Inserts is a unique technology aimed at increasing the power density of wind turbines.

The Freudenberg Friction Inserts (FFI) technology is based on a special very thin nonwoven carrier material coated on one side with hard particles. The FFI are customized to fit each application, in terms of both the geometry and the construction parameters of the connection. As they do not create a gap they can be applied exactly where they are needed.

When placed in the joint, these hard particles penetrate into the surfaces of the two joining parts creating a micro interlock, thus reliably increasing the friction coefficient and achieving higher torque transmission in connections. This results in higher performance and a significant improvement in the efficiency of wind turbines. In addition, it enables the downsizing of components without compromising performance, reducing weight and material.

FFI help to improve the reliability of connections and thus of the entire wind turbine. Furthermore, they eliminate slipping and prevent fretting of connections.

Other examples of applications for FFI are highly loaded flange connections between the rotor shaft and gearbox, connections between the main bearing and the machine carrier housing, the gearbox to generator, or at the pitch gear or ring gear. They increase the friction co-efficient between two components.

Ziel des Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE ist es, die Wertschöpfungskette Kunststoff zirkulär zu gestalten. Sechs Fraunhofer-Institute erforschen am Beispiel Kunststoff, wie der Wandel von einer linearen zur einer zirkulären Kunststoffwirtschaft gelingen kann. Auf der ACHEMA in Frankfurt, der internationalen Messe für die Prozessindustrie, stellt das Fraunhofer CCPE vom 22. bis zum 26. August zwei technische Produktinnovationen und ein Bewertungstool für Unternehmen der Circular Economy vor.

Seit 2018 erforschen die sechs Fraunhofer-Institute — IAP, ICT, IML, LBF, IVV und UMSICHT – wie eine nachhaltige Transformation einer gesamten Wertschöpfungskette unter Prinzipien der Circular Economy erfolgen kann. Durch einen Multi-Stakeholder-Ansatz können FuE-Kompetenzen gebündelt werden, um Produkte zirkulär zu gestalten, passende Geschäftsmodelle zu entwickeln und End-of-Life Verluste bei Kunststoffabfällen zu reduzieren. Auf der ACHEMA werden die folgenden Projekte ausgestellt:

• Faserverstärktes Monomaterialkomposit aus PLA
  Biobasierte Kunststoffe werden zunehmend für technisch anspruchsvolle Einsatzbereiche z.B. in der Automobil- und Textilindustrie nachgefragt. Zwei zentrale Anforderungen sind dabei ihre Stabilität und ihre Recyclingfähigkeit. Forschende der Fraunhofer-Institute IAP und ICT entwickelten innovative PLA-basierte Monomaterial-Komposite (Organobleche), die technische Applikationen adressieren und insbesondere mit Hinblick auf die Rezyklisierbarkeit einen Beitrag zur Umsetzung der Sustainable Development Goals der UN leisten können.
• Optisch und mechanisch verbesserte Folienrezyklate
  Bei der Herstellung von Folien zählt neben den mechanischen Eigenschaften besonders der visuelle Eindruck. Es dürfen keine Fehlstellen in Form von Stippen, Fischaugen oder Abrissen auftreten, die insbesondere bei Verwendung von Rezyklaten zu Problemen führen können. Die direkte Verwendung eines Folienregranulats führt jedoch häufig zu vielen Abrissen während der Folienherstellung, die zudem fatale Auswirkungen auf die mechanischen Materialeigenschaften haben. Durch die Zugabe einer geeigneten Additivformulierung konnte die Folienqualität nun signifikant verbessert werden.

Ist ein Produkt reif für die Circular Economy?
Weiterhin präsentieren die Forschenden nun auf der ACHEMA das webbasierte Tool CRL®, mit dem Unternehmen den Reifegrad von Produkten oder Produktsystemen im Hinblick auf die Circular Economy selbst bewerten können. Es prüft, inwieweit ein Produkt die Strategien der Kreislaufwirtschaft in den Bereichen Produktdesign, Produktdienstleistungssystem, End-of-Life-Management und Kreislaufwirtschaft bereits berücksichtigt und wo noch Verbesserungspotenzial besteht.

According to the World Health Organization (WHO), cardiovascular disease is one of the most common natural causes of death. Every year, it is the cause of death of around 17 million people worldwide. The Peter Dornier Foundation Prize 2022 has now awarded a research work that is to improve the medical care of people with insufficient heart valve function in the future and prolong the patients' lives.

The human heart is a high-performance machine: over the course of a person's life, it beats almost three billion times, pumping around 200 million litres of blood through the body. Enormous stresses that can sometimes lead to life-threatening signs of wear and tear. If a heart valve gets out of step, patients usually get artificial-mechanical or biological valves as a replacement. However, mechanical solutions imply patients to take blood-thinning medication for the rest of their lives. In addition, there may be audible closing noises. For example, almost a quarter of patients with mechanical heart valves complain of sleep disturbances. Biological heart valves, on the other hand, such as those made from animal tissue, require a great deal of manual work and have a shorter lifetime.

Potential of weaving for medical products demonstrated
For this reason, Graduate Engineer Mathis Bruns at the Institute for Textile Machinery and High-Performance Textile Materials Technology (ITM) at the TU Dresden is researching an implant alternative made of fabric. As part of a research project that also involved heart surgeons from the Dresden Heart Centre and the University Hospital in Würzburg, Mr. Bruns provided important findings for weaving an artificial heart valve in his diploma thesis. For his work entitled "Development of tubular structures with integrated valve function", Mathis Bruns has now received the Peter Dornier Foundation Prize 2022, endowed with 5,000 euros. In his laudation, Dr. Adnan Wahhoud, former head of the development department of air-jet weaving machines at DORNIER in Lindau, said: "With his work, the winner of the award demonstrates very clearly the potential of weaving technology to produce fabrics of complex form, geometry and structure with the aim of prolonging and improving people's lives." The award-winning thesis enriches research into three-dimensional tissues for use in medicine.

Weaving replacement heart valves without seams
"A particular advantage of our approach is the integral production method", says foundation prize winner Mathis Bruns. “The geometry and function of a heart valve is that complex that woven heart valves could not be produced in this form previously. Through the combined use of a rigid rapier weaving machine with bobbin shield and a Jacquard machine, it is possible to weave the replacement heart valve in such a way that it no longer has be sewn together. Even the tubular structures for the blood vessels and the integrated valve function are ‘all of one piece’. Seams are always a weak point in textile medical products," Mr. Bruns adds. “Another advantage of the woven heart valve is the possibility to insert it by the help of minimally invasive surgery. Hence, the folded valve which is about the size of a tea light is to be pushed with a catheter via the bloodstream to the target position in the heart and unfolded there. The patient's chest and heart would then no longer have to be cut open”, explains prize winner Mr. Bruns.

Textile structure is similar to human tissue
A wide variety of medical products have always been produced on DORNIER weaving machines. Customers use them to produce fabrics for bandages, prostheses, blood filters and orthoses among other things. For Mathis Bruns, it is only evident that implants such as heart valves will more and more be woven on the machines from Lindau in the future. "Textile tissue is very similar to human tissue," he says. The human body consists largely of thread-like materials, just as a textile fabric is made up of thousands of individual threads. "Muscle fibres convey force impulses, nerve tracts send stimuli such as pain and brain cells convey information via thread-like dendrites and axons." Because of their ‘thread-like properties’, woven implants are therefore particularly suitable for medical applications.
