From the Sector

• Das große Kompendium bezieht erstmalig auch Reader in seine Studien ein und zeigt Lösungen zu den Verwerfungen am Chipmarkt auf.

Die neueste Ausgabe der bisher als UHF Tag Performance Survey (UTPS) bekannten Studie stellt die Performance von 550 Tags erstmalig in Beziehung zu 36 Readertypen. Im RFID Markt steht der technisch und wirtschaftlich dynamischen Entwicklung auf Chip- und Transponderseite eine Konsolidierung auf Readerherstellerseite gegenüber. Immer öfter sind RFID-Reader der limitierende Faktor in Bezug auf Performance, Zuverlässigkeit und Funktionalität des Gesamtsystems. Der Almanach zeigt die vielen Stellschrauben auf, um RFID-Systeme zu optimieren.

Nam Tran, Leiter des EECC Messlabors erklärt: „Die Backlink-Matrizen des Almanachs können Fragestellungen dabei nach mehreren Einflussgrößen gleichzeitig auflösen. Ob Tags z.B. in großen Populationen eingesetzt werden können oder auch in sehr unterschiedlichen Lese-Situationen funktionieren; ohne den Almanach könnte der Anwender meist nur in einer dieser Dimensionen optimieren.“

Auch ohne Chip-Krise; in zunehmender Maße betreffen viele der genannten Fragestellungen vor allem ältere Chipgenerationen und die darauf optimierten Anwendungen. Beispielsweise wenn Chips nicht mehr produziert werden oder Hersteller vom Markt verschwinden. Für diese Bestandslösungen, die auf älteren, weniger sensitiven Chiptypen beruhen, deuten sich für die Zukunft Ausweichmöglichkeiten auch auf chinesische Chiptypen an; eine Entwicklung aus dem amerikanisch - chinesischen Handels-Wettstreit der letzten Jahre.

Der Nutzen des EECC UHF RFID Almanach 2021 liegt nunmehr auf beiden Seiten des RFID-Gesamtsystems. Wird ein System neu installiert oder aber die Reader-Infrastruktur verändert, kann der Effekt auf der Transponderseite direkt abgeschätzt werden. Andersrum aber kann ein optimaler Reader mit den Ergebnissen aus dem EECC Almanach ausgewählt und parametriert werden. Auch beim Einsatz von gemischten Transponder-Populationen.

Mit dem EECC UHF RFID Almanach 2021 möchte das EECC im größtmöglichen Umfang alle relevanten Situationen des UHF-RFID-Einsatzes messtechnisch nachbilden. Er liefert Antworten auf alle Fragen, vor die wir aus technischen, aber auch politischen und wirtschaftlichen Gründen gestellt werden.

Originally conceived as a low-cost, high-volume alternative to knitting and weaving, nonwovens was already expanding its market boundaries by the 1970s with new applications in ‘disposables’ such as diapers, hygiene and teabags.

In the past five decades, the nonwovens business has exploded in all directions, reaching a global market worth USD 40.5 billion in 2020, projected to grow to USD 53.5 billion by 2025. This annual growth rate of 5.7% (MarketsandMarkets, Nonwoven Fabric Market Report) is based on countless new applications and expansion into durable, as well as additional disposable, products.

Major growth drivers include the hygiene sector, and filtration media for power plants and air conditioning systems. Especially during the peak of the COVID pandemic in 2020 and 2021, demand in the hygiene sector multiplied. Worldwide capacities for both meltblown and spunlace production rocketed compared to a normal business year. Swiss Autefa Solutions, for example, significantly benefited from this trend, notably with the launch of a fully-automatic machine for producing face masks.

The automotive industry is the second big growth area, with many new applications being pioneered. The trend to electric and hybrid vehicles has helped this, as nonwovens reinforced with carbon fibres are widely used as battery housings.

Swiss nonwovens competence
Innovative applications across all sectors have driven the rapid evolution of sophisticated nonwovens machinery. Today’s trends demand higher productivity, sustainability and Industry 4.0 compatibility – demonstrated by the full equipment portfolio of Swiss Textile Machinery member Autefa Solutions. With V-Jet Futura, the company recently sealed the link in its product range between web forming and drying technology. This latest Hydroentanglement Machine, together with the SQ-V Square Drum Dryer, embodies advanced technology combined with significant reductions in energy consumption compared to other process solutions.

A vital contribution to nonwovens production is offered by Rieter subsidiary Graf, a leading supplier of clothing and combs for carding and combing processes in spinning and nonwovens. Graf's Hipro card clothings – suitable for any man-made fibres in the nonwovens sector – are focussing on higher productivity. Their superior performance delivers up to 10% higher throughput and greater carding efficiency compared to conventional clothings. These reliable card clothing elements also ensure a consistently reproducible high web quality, as well as 20% fewer failures in the web, thanks to the precise fibre transfer to and from the cylinder.

Another constant trend in nonwovens today is the drive for better quality. Manufacturers want to take charge of contamination levels in their processes, as well as eradicating defects which may arise during production. Uster Technologies, a leading provider of quality management solutions from fibre to fabric, offers a combined solution to achieve both these required quality standards. At the fibre preparation stage, Uster Jossi Vision Shield N ensures the best possible initial inspection and removal of contamination. Then, at the end of the production sequence, Uster EVS Fabriq Vision N handles automated detection and marking of all the main defects caused during production. This combined solution avoids material waste and takes full advantage of the potential for process optimization.

• Renewably Sourced Materials to Help Replace Petrochemicals in Apparel for a Healthier Planet

lululemon athletica inc. (NASDAQ:LULU) announced a multi-year collaboration with sustainable materials leader Genomatica to bring renewably-sourced, bio-based materials into lululemon’s products. This represents lululemon’s first-ever equity investment in a sustainable materials company and Genomatica’s largest partnership within the retail industry.

Genomatica uses biotechnology and fermentation to convert plant-based ingredients into widely used chemical building blocks, like those used to make nylon. These building blocks are converted to pellets and yarns, and the companies will be working closely with lululemon’s fabric supply chain to incorporate this material into future products. Through this collaboration, the companies seek to create positive change within the $22B global nylon market by building more sustainable supply chains.  

As the Rieter Holding Ltd. Announced, during the course of the acquisition of three Saurer businesses’, it came to serious violations of the statutory duty of loyalty, the obligation to maintain business secrets and the Rieter Code of Conduct by two members of the Board of Directors. They are said to have misused information internal to the Board of Directors in order to compete with Rieter through an offer of their own.

The Board of Directors considers this to be a strong violation of Rieter’s interests, to the detriment of all of its stakeholders, and a sustained breach of the relationship of trust within the Board of Directors which makes further cooperation impossible.

Therefore, the Board of Directors of Rieter Holding Ltd. intends to convene an Extraordinary General Meeting to dismiss these members. Furthermore, to protect Rieter’s interests, the Board of Directors will file a criminal complaint against them.

Weko Holding GmbH has taken over RotaSpray GmbH from Oehringen with retroactive effect from January 1st, 2021 and further expands its textile segment.

With the merger of the two companies, the competencies in the field of functional wet finishing, digital printing pre-treatment and spray dyeing processes will be bundled for the textile segment. Both companies believe that these segments offer good future opportunities, because the demand for a resource-saving, CO2-reduced dyeing and finishing process for textile yarns and fabrics is increasing rapidly. Likewise the market trend of ever smaller production lot sizes per order.

RotaSpray GmbH will continue to be managed as an independent unit within the WEKO Holding Group and will focus purely on the high-quality textile sector.
WEKO has been developing and producing non-contact application systems for product optimization and surface finishing with different types of liquids and powdery substances since 1953. The areas of application are broad and the nonwovens, paper, tissue, printing, wood fiber boards, foils and metal industries are successfully supported with WEKO solutions.

Autoneum carpet systems already meet high standards of sustainable mobility due to their high content of recycled fibers. Thanks to an alternative backcoating (ABC) process, Autoneum carpets are now becoming even more environmentally friendly: By replacing the latex commonly used in standard backcoatings with thermoplastic material, the recyclability of carpets at the end of product life is further  improved. In addition, the innovative manufacturing process greatly reduces water and energy consumption and thus CO2 emissions in production.

Lightweight, textile-based carpet technologies such as Di-Light or Relive-1 significantly improve the environmental performance of carpets. For example, Di-Light-based carpets consist of up to 97% recycled PET; aside from that, they are around 20% lighter than conventional needlepunch carpets, thus contributing to lower fuel consumption and CO2 emissions from vehicles. In addition, Autoneum needlepunch carpets are now even more sustainable thanks to the innovative ABC process, which uses a thermoplastic adhesive instead of latex in the backcoating: Unlike latex, thermoplastic adhesives can be heated and melted down together with the carpet components made of pure PET at the end of the product life cycle, which facilitates recycling considerably. Furthermore, since the fibers of the thermoplastic mono-material are easier to open, carpet cut-outs can be reclaimed more easily, thereby reducing the consumption of natural resources as well as waste volumes and thus CO2 emissions. The environmental  performance of Autoneum’s needlepunch carpets, which already contain a high proportion of recycled PET, is thus further improved.

Moreover, backcoatings without latex improve the sustainability of carpets not only thanks to better recyclability at the end of the product life cycle. Since the application of the thermoplastic adhesive using the innovative ABC process consumes significantly less energy than the production of latexbased backcoatings and does not require any water at all, the environmental impact can already be minimized in the manufacturing process. Additionally, thermoplastic adhesives developed in-house by Autoneum will open up new possibilities in the future for adapting backcoatings to the individual needs of vehicle manufacturers in terms of their acoustic performance, stiffness and abrasion resistance.

Models from various customers in Europe and North America are already equipped with latex-free needlepunch carpets from Autoneum. In the near future, backcoatings with thermoplastic adhesives will also be used for Autoneum’s tufted carpets. Production of the new, even more sustainable generation of tufted carpets is scheduled to start in early 2022.

Hexcel, a global leader in advanced composites technologies, announces the successful maiden flight of a lightweight camera drone, developed using Hexcel HexPly® carbon fiber prepregs. The composite drone was developed by a team of students from the University of Applied Sciences Upper Austria in Wels with composite materials supplied by Hexcel Neumarkt in Austria.

A team of six students in the university’s lightweight construction and composite materials course was responsible for the complete design, engineering, and manufacture of the camera drone over a period of 18 months. Hexcel materials and optimization of the composite engineering enabled the team to reduce the composite structural mass by an impressive 42% compared to similar drones.

Hexcel Neumarkt was one of eight industrial partners supporting the university team throughout the project, providing all carbon fiber prepreg materials used for the drone’s landing gear as well as the fuselage. The ultra-lightweight 32g landing gear was laid up and cured in the press, whereas the fuselage was autoclave cured by the student team using Hexcel HexPly M901 and HexPly M78.1 prepreg resin systems with a combination of woven and unidirectional carbon fiber reinforcements.

With the development of Unmanned Aerial Vehicles (UAV) as a key emerging market and innovation space in the transportation sector, Hexcel’s collaboration with the University of Applied Sciences Upper Austria team not only creates an important link with the next generation of lightweight composite engineers but also highlights the weight saving and structural benefits of Hexcel composite material solutions.

"The massive weight saving achieved with their updated version of the camera drone is a fantastic achievement by the student team," said Michael Rabl, Dean of FH Wels of the Upper Austria University of Applied Sciences. "The joint study not only illustrates the wide range of complex and innovative composite techniques present in the drone sector but also presents the opportunities that exist for further development in the wider Urban Air Mobility (UAM) and aerospace composites markets.”

Hexcel congratulates the project team which includes Lukas Weninger, Karl-Heinz Schneider, Jakob Schlosser, Matthias Thon, Marla Unter, and Simone Hartl on an exceptional piece of lightweight composite design and thanks them for showcasing the contribution of Hexcel materials with a presentation and drone flight. Johanna Arndt, research and technology group leader at Hexcel Neumarkt, said, “It was a great pleasure to work with the team who were very cooperative and self-motivated to succeed. Watching the drone just fly around the Neumarkt plant was just great.”

Hexcel manufactures a complete range of carbon fibers, dry carbon UD tapes, specialty reinforcements, prepregs, and honeycomb core materials, providing customized manufacturing options for new UAM applications that combine aerospace reliability with the high-rate production required. Hexcel composite materials are the ideal solution for the lightest and most efficient cost-competitive transportation vehicles of the future.
