Textechno reports launch of a new standard for the drapability and deformability of fabrics and non-wovens: ISO 21765

World market leader for precision testing equipment Textechno and their partner SAERTEX, global market leader in non-crimp fabrics (NCF) are proud to announce that the newly developed international standard ISO 21765:2020 to quantify material behaviour in terms of drapability and deformability was recently published by ISO.

The new standard ISO 21765 allows the world-wide comparable measurement of all relevant parameters regarding the deformability and drapability of all kinds of fabrics, including woven fabrics and NCFs as well as knitted fabrics and non-wovens on Textechno´s precision testing equipment DRAPETEST. This can be very useful in the carbon fibre recycling since one of the most efficient applications of recycled carbon fibres will be in non-wovens.

This is the first testing instrument world-wide to quantify not only the force which is required for deforming a fabric, but also the various defects such as gaps, undulation, or wrinkles which can arise due to the deformation.

In the frame of a publicly funded project which started in 2011, Textechno developed the award-winning automatic drapability tester DRAPETEST along with other partners, amongst them SAERTEX.  

Dietmar Möcke, CTO at SAERTEX says: „With ISO 21765, we finally have a standardized testing method with world-wide validity. It allows us to provide our customers with comparable and reproducible measurement values regarding the draping characteristics of our products.”

Ulrich Mörschel, Managing Director of Textechno adds: “We are grateful for the support from all around the world allowing us to establish the new ISO standard. The standard finally fills a gap in the testing methods for fabrics both in the fields of textiles and composites.”

Dr. Michael Effing, Managing Director of AMAC GmbH and Senior Advisor to Textechno: “A lot of research is dedicated to new production technologies of composites, non-crimp fabrics and classical fabrics for thermosets have with 33 % a significant market share in the production of all composite materials. The application of the new standard for non-wovens from recycled carbon fibres comes perfectly on time for this market sector which will gain more and more importance within the next years.

Fibre Extrusion Technology of Leeds, UK has delivered nine meltspinning systems to clients in the biomedical sector since the onset of the Covid-19 pandemic, with a similar number currently on order for 2021/22. This way FET could confirm the position as an acknowledged world leader in meltspinning equipment for the production of precursor materials used in medical devices and as a default supplier for absorbable suture production systems, with orders virtually doubling year on year.

Recent installations include a multi-functional system that can produce both multifilament and monofilament pre-cursor fibres, but nonwoven systems have been particularly prominent, driven by the burgeoning demand for FFP3 masks, gowns and other medical products required during the pandemic. These have been sold to medical device manufacturing companies across the globe, including the Far East, USA and Europe. Research organisations have also invested in FET systems for biomedical applications, the most recent being the University of Leeds in a laboratory scale Spunbond system.

The FET in-house Process Development Laboratory and ongoing collaboration with biomaterial polymer suppliers has helped to optimise the biomedical melt spinning technology. The Laboratory is at the disposal of customers for all aspects of confidential testing and evaluation. To further increase this competitive edge, FET will be opening a new Process Development Laboratory and Visitor Centre in early 2022.

• New brand Trevira CS eco

After a challenging 2020 for Trevira CS®, a year in which the coronavirus crisis put pressure on the contract market, in particular on the hotel and event sector, and also on the cruise shipping industry, the market is starting to show some signs of improvement. Numerous new developments are seizing upon the trends that have emerged since the crisis began.

Although the coronavirus pandemic had a negative effect on individual business sectors, it also has the potential to open up new market opportunities for flame retardant Trevira CS fabrics in the long run. The increase in people working from home and the longer and more frequent stay within one’s own home have led to a change in perspective in terms of the relevance of interior design. The design of the living space has undergone a revaluation. Sustainability, durability, high quality, and the desire for safe products that contain little to no harmful substances are defining criteria for selecting a new textile interior. The colour range of the new Trevira CS developments is directed specifically towards this trend and often comes across as discreet and close to nature. After Trevira CS products have found their way more and more into private homes, the new Trevira CS collections include numerous attractive textiles not only for the contract sector but also for the residential sector.

In the contract sector, notably in the hotel industry, the trends towards sustainability and quality are likely to continue to grow. Moreover, there is an increase in awareness as far as hygiene requirements are concerned. Textiles that are easy to clean without losing their appearance or their functionality can excel here. Accordingly, products ordinarily used in the healthcare sector might start to be of interest to the hotel and catering industry, public spaces, the transport industry, and to offices. This will apply in particular to areas where there is a regular flow of visitors and where people come into direct contact with fabrics. Antimicrobial textiles provide additional protection in these situations. Besides their flame retardancy, many new Trevira CS products integrate additional functions such as noise or sun protection.

Trevira has launched the Trevira CS eco brand for flame retardant textiles that consist of recycled Trevira products.
The new Trevira CS eco brand unites sustainability and flame retardancy. Trevira offers products for this which have been manufactured through different recycling processes. The flame retardant filament yarns are based on the use of recycled PET bottles (post-consumer recycling). Textiles bearing the Trevira CS eco trademark consist of at least 50% recycled materials.

Trevira uses an agglomeration facility to recycle reusable waste materials from production to manufacture recycled fibres that, after further processing, retain the same quality and performance characteristics as the original products (pre-consumer recycling).

• 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. Together, the two companies will create a lower-impact, plant-based nylon to replace conventional nylon, which is the largest volume of synthetic material currently used to make lululemon products.

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.
