From the Sector

Vom 25. bis zum 27. April 2023 findet die diesjährige JEC WORLD, die international führende Leichtbaumesse, in Paris statt. Das Sächsische Textilforschungsinstitut e.V. (STFI) wird seine jüngsten Innovationen aus dem textilen Leichtbau und dem Textilrecycling auf dem Stand der sächsischen Wirtschaftsförderung präsentieren. Das STFI fokussiert seinen Messeauftritt in Paris dieses Jahr vor allem auf erfolgreiche Beispiele aus Industriekooperationen, die zur Nachhaltigkeit des Herstellungsprozesses beitragen.

Im Forschungsvorhaben „optiformTEX“ innerhalb des BMBF-Förderprogramms „Zwanzig20 – futureTEX“ wurde eine neue Technologie für flächige Naturfaser (NF)-Halbzeuge mit belastungsgerechter topologischen Fasermasseverteilung entwickelt. Dies lässt eine signifikante Gewichtsreduzierung von bis zu 30 % bei Leichtbauteilen vor allem im automobilen Interieur zu.

Es entstand das Modul „3D-Lofter“ zur lokalen Verstärkung von Vliesstoffen mittels definierter Faseranhäufungen; entwickelt und gebaut durch den Projektpartner Oskar Dilo Maschinenfabrik KG, Eberbach. Ein Exemplar des Moduls wurde in eine Labornadelvliesstoffanlage im Technikum des STFI integriert und steht für Kundenversuche sowie nachfolgende Forschungsvorhaben zur Verfügung.

Im Ergebnis des internationalen BMBF-Vorhabens „HiPeR – Orientierte Carbonfaserstrukturen aus Luftfahrt-Produktionsabfällen zum Wiedereinsatz im Flugzeug“ entstand ein Strukturbauteil für die Luftfahrt aus Recycling-Carbon. Dafür wurden am STFI rCF-Tapes sowohl aus recoverten, mechanisch aufbereiteten Abfällen als auch aus pyrolysierten Fasern entwickelt. Die rCF-Tapes werden auf dem STFI-Stand, das Bauteil selbst am CU-Messestand/CTC präsentiert.

Freudenberg Performance Materials (Freudenberg) is widening its product range of technical packaging textiles. Evolon® ESD protects automotive and industrial parts with electronic components from electrostatic discharge. This includes trim lines, dashboards, mirrors, steering wheels, etc.

The ESD (ElectroStatic Discharge) feature of the new Evolon® technical packing textile provides permanent electrostatic discharging protection and the fabric’s surface resistivity can be customized. This eliminates ESD damage to electronic components during transport because electrostatic charging due to movement and friction is safely prevented. As this kind of damage cannot be detected with the naked eye, Evolon® ESD helps to avoid failures which can occur after the final product is assembled and released. Manufacturers benefit from fewer complaints and warranty costs, as well as better end customer satisfaction.

Further protection feature
Unlike conventional ESD packaging solutions, Evolon® ESD also protects parts surfaces by avoiding micro-scratches or lint contamination. By using Evolon® reusable packaging to transport parts with highly-sensitive surfaces, customers reduce the number of damaged parts and the reject rate.

Additional benefits
Evolon® microfilament textiles are also extremely strong and are available in different weights to meet a wide range of requirements – from lightweight to heavy-duty. They can be used to pack and transport very heavy parts without damage. In addition, Evolon® fabrics are durable, and contain up to 85% recycled PET.

Freudenberg Performance Materials (Freudenberg) will present surfacing veils and core materials for lightweight fiber reinforced plastic (FRP) parts at JEC in Paris, France. Freudenberg will also be showcasing Enka® Solutions flow media and spacers for efficient vacuum infusion, resin transfer and foam injection molding processes for applications in the composites industry, etc. at the international composites show.
 
Freudenberg’s solutions for the FRP industry include a variety of glass, PAN and PET nonwovens, as well as core materials for the production of lightweight fiber reinforced plastic parts. These products are designed for anti-corrosion coatings in piping and tank construction, smooth UV resistant surfaces for facade panels, and other applications for a diverse range of end products. Products made from fiber reinforced plastics must be equipped with surfacing veils to provide abrasion resistance, corrosion resistance, smooth surfaces and mechanical strength. Freudenberg offers high-tech nonwovens that can meet these challenges.
 
Enka® Solutions products are characterized by their typical 3D entangled polymeric filament structures. Thanks to this structure, they are exceptionally suitable as flow media and spacers when producing composite materials.

With China easing its pandemic restrictions, foreign exhibitors and buyers can look forward to quarantine-free travel when participating at this year’s industry showcase in Shanghai. The technical textile and nonwovens fair is scheduled to take place from 19 – 21 September 2023 at the Shanghai New International Expo Centre, amid positive market forecasts for both sectors. The organisers are anticipating a strong showing and the conclusion of an inconsistent period for in-person textile business.

“The industry has demonstrated incredible patience and resilience over the course of the pandemic,” said Ms Wilmet Shea, General Manager of Messe Frankfurt (HK) Ltd. “With both markets growing and China opening its borders, we are excited at the prospect of providing participants with an international, business-friendly platform and expect to welcome a healthy number of exhibitors later this year.”

The global technical textile and nonwovens markets are both set to perform strongly over the next few years. According to Grand View Research, the technical textile market is forecast to expand at a CAGR of 4.7% from 2022 to 2030^[1]. The nonwoven fabrics market is anticipated to display an even stronger CAGR of 5.6% during the same period^[2], with Asia-Pacific to maintain its position as the biggest regional market.

As one of Asia’s leading trade fairs for the abovementioned sectors, Cinte Techtextil China is the preferred platform for multiple industry players. Speaking at the previous edition in 2021, Mr Seven Shen, Sales Manager at Libero Trading (Shanghai) Co Ltd, China, said: “We have been exhibiting at this fair for years, and know we will meet our target customers at every edition. The buyers here are all highly specialised.”

During his interview at the same edition, Mr Eric Ni, Senior Manager, China Supply Chain Marketing for Cotton Council International, USA, commented: “We hope to use this platform to meet more companies and brands in the nonwovens industry who are interested in US cotton, and to meet up with old friends to discuss the current situation and industry trends. The fair’s buyers are quality, and we have found some new potential clients at this edition.”

Many buyers at the previous edition also gave positive appraisals. “As a professional trade fair for technical textile and nonwoven products, Cinte Techtextil China is not only a platform to gather qualified industry players, but also the best place to showcase new products and innovations,” said Mr Lin Bin, Technical Director at Zhejiang Xinna Medical Device Technology Co Ltd, China. “Specific and high quality products enhance sourcing efficiency for buyers, and exposure to new trends and market developments ensures my company visits here regularly.”

The fair’s product categories cover 12 application areas, which comprehensively span a full range of potential uses in modern technical textiles and nonwovens. These categories also cover the entire industry, from upstream technology and raw materials providers to finished fabrics, chemicals and other solutions. This scope of product groups and application areas ensures that the fair is an effective business platform for the entire industry.

Es ist eine der beliebtesten Veranstaltungen am Fachbereich Textil- und Bekleidungstechnik der Hochschule Niederrhein: die Präsentation der Ergebnisse der Projektarbeiten aus dem fünften Semester. „Die Studierenden sammeln in dieser besonderen Lehrveranstaltung wertvolle Praxiserfahrung, da sie die Problemstellungen realer Auftraggeber unter industrienahen Bedingungen bearbeiten“, sagt Professorin Dr. Kerstin Zöll, Leiterin der Steuerungsgruppe.

14 Teams wurden nach dem Zufallsprinzip interdisziplinär und teilweise international zusammengestellt, das Projekt und der Auftraggeber zugelost. Die Ergebnisse zeigen, worauf im Fachbereich Textil- und Bekleidungstechnik besonderer Wert gelegt wird: Die Lösungen sind innovativ, smart, nachhaltig und ressourcenschonend. Viele Produkte können auf verschiedene Art modular genutzt oder nach Gebrauch weiterverwendet werden. Den ersten Platz belegte das von Epson Deutschland GmbH unterstützte Projekt „Multifunktionales Outfit für Kinder für einen sicheren Schulweg“.

Da Kinder auf ihrem Schulweg besonders in der dunklen Winterjahreszeit einigen Gefahren ausgesetzt sind, hat das Projektteam eine Outdoorjacke mit passenden Accessoires entworfen, die durch leuchtende und fluoreszierende Farben für mehr Sichtbarkeit sorgt. „Warnwesten werden von Kindern eher ungern getragen“, sagt Andreas Stephan, Manager Business Development Commercial & Industrial Printing bei Epson. So führten die Studierenden Umfragen mit Grundschulkindern durch und entwarfen daraufhin ein zeitloses genderneutrales Design mit bunten Monstern (den „Loumis“) und einem dunklen, schlichten Reflektorstoff.

Andere Studierende beschäftigten sich mit einer innovativen und nachhaltigen Lösung zur Unterstützung der Interaktion von Fans im Stadion von Fußball-Bundesligist Borussia Mönchengladbach. Auftraggeber war der Elektrofachgroßhandel Sonepar Deutschland GmbH. Entstanden ist eine Weste aus nachhaltigen Materialien mit einer besonderen Funktion. Die Lautstärke des Torjubels wird durch einen Mikrofonsensor in der Weste in Vibration umgewandelt, die im Schulterbereich spürbar ist. Das gesamte Projekt steht unter dem Ansatz, ob die Weste mit ihrer Vibration dazu beiträgt, dass schwerhörige beziehungsweise gehörlose Menschen intensiver am Spielgeschehen teilhaben.

Eine Hommage an das Ruhrgebiet entstand mit einer Modekollektion zum Thema „Schlackenritter“. Themensteller war die thyssenkrupp AG. Der Fokus lag auf Nachhaltigkeit und dem thematischen Bezug zum Ruhrpott. Inspiration war die Arbeitskleidung der Schlackenritter, Männer, die in langen, meist silbernen Schutzmänteln, am Hochofen arbeiten. Die moderne, stylische, dem Ruhrpott und seiner Industrie gewidmete Kollektion besteht aus sieben Teilen: einem Hoodie, einer Cargo Hose, einer Jeans Hose, zwei T-Shirts, einem Hemd und einer Tasche. Wobei diese zumeist sowohl für Frauen als auch für Männer als Unisex ready-to-wear sind.

Zu den Klängen von Scott McKenzies Hit „San Francisco“ aus dem Jahr 1967 präsentierte ein Projektteam eine Innenausstattung für einen Estafette Camper aus demselben Jahr. Angelehnt an die Flower-Power-Zeit fanden mittels Textildruck viele Orangetöne Einzug in das von der Firma Multiplot Europe GmbH zur Verfügung gestellte Fahrzeug. Angereichert wurde es mit besonderen Features wie einer Beamer-Leinwand, die gleichzeitig auch als Sonnensegel genutzt werden kann.

By using a high share of recycled content in its Evolon® materials, Freudenberg Performance Materials (Freudenberg) offers technical packaging textiles with a carbon footprint decreased by 35%. An independent LCA study showed additional benefits such as energy resource savings and lower water use. Furthermore, Evolon® fabrics provide sustainability benefits over the packaging entire life cycle thanks to high end performance and durability.

By replacing virgin PET with recycled PET, the cradle-to-gate carbon footprint of Evolon® packaging textile materials decreased by 35%. This is the result of a study by an independent LCA and eco-design consultancy firm, which made a Cradle-to-Gate assessment of several Evolon® products using virgin PET or recycled PET. The study was finalized in 2022 and conducted according to the principles of ISO 14040/ ISO 14044 standards, following the recommendations of the Product Environmental Footprint and the Circular Footprint Formula.

Evolon® microfilament textiles have a small carbon footprint because their manufacturing process uses low CO2 energy sources. The fabrics are lightweight and can be reused throughout entire production programs, e.g. of a car model when it is about the automotive industry. Furthermore, the new Evolon® RE fabrics contain up to 85% of recycled PET which is produced in-house out of post-consumer PET bottles.

Evolon® textiles are suitable for reusable technical packaging, which eliminate the use of thousands of disposable packaging materials. Evolon® fabrics offer scratch-free, lint-free, high-end surface protection for molded plastic parts, painted parts and other sensitive industrial and automotive parts during transport. This contributes to lower the scrap rate of parts and provide both financial and ecological benefits. By using Evolon® reusable packaging to transport highly-sensitive parts, customers can increase their efficiency and save resources.

Many people across the world are bedridden – be it due to illness, an accident or old age. Because those affected often cannot move or turn over by themselves, they often end up with very painful bedsores. In the future, it should be possible to avoid bedsores with the help of materials that can be programmed to entirely adapt their form and mechanical properties. For example, the body support of mattresses made from programmable materials can be adjusted in any given area at the push of a button. Furthermore, the support layer is formed in such a way that strong pressure on one point can be distributed across a wider area. Areas of the bed where pressure is placed are automatically made softer and more elastic. Caregivers can also adjust the ergonomic lying position to best fit their patient.

Materials and microstructuring
Materials for applications requiring specific changes to stiffness or shape are being developed by researchers from Fraunhofer CPM, which is formed of six core institutes with the aim of designing and producing programmable materials. So, how can we program materials? “Essentially, there are two key areas where adjustments can be made: the base material – thermoplastic polymers in the case of mattresses and metallic alloys for other applications, including shape memory alloys – and, more specifically, the microstructure,” explains Dr. Heiko Andrä, spokesperson on the topic at the Fraunhofer Institute for Industrial Mathematics ITWM, one of the Fraunhofer CPM core institutes. “The microstructure of these metamaterials is made up of unit cells that consist of structural elements such as small beams and thin shells.” While the size of each unit cell and its structural elements in conventional cellular materials, like foams, vary randomly, the cells in the programmable materials are also variable – but can be precisely defined, i.e., programmed. This programming can be made, for example, in such a way that pressure on a particular position will result in specific changes at other regions of the mattress, i.e., increase the size of the contact surface and provide optimal support to certain areas of the body.

Materials can also react to temperature or humidity
The change in shape that the material should exhibit and the stimuli to which it reacts - mechanical stress, heat, moisture or even an electric or magnetic field - can be determined by the choice of material and its microstructure.

The journey to application
A single piece of material can take the place of entire systems of sensors, regulators and actuators. The goal of Fraunhofer CPM is to reduce the complexity of systems by integrating their functionalities into the material and reducing material diversity. We always have industrial products in mind when developing the programmable materials. As such, we take mass production processes and material fatigue into account, among other things,” says Franziska Wenz, deputy spokesperson on the topic at the Fraunhofer Institute for Mechanics of Materials IWM, another core institute of Fraunhofer CPM. The initial pilot projects with industry partners are also already underway. The research team expects that initially, programmable materials will act as replacements for components in existing systems or be used in special applications such as medical mattresses, comfortable chairs, variable damping shoe soles and protective clothing. “Gradually, the proportion of programmable materials used will increase,” says Andrä. Ultimately, they can be used everywhere – from medicine and sporting goods to soft robotics and even space research.
