From the Sector

The recent Techtextil show in Frankfurt emphasised the diversity of applications for nonwovens and technical textiles, according to finishing technology specialist Monforts.

“We fielded enquiries at top management level from an extremely wide range of companies, all with very different ideas for new product applications during the show,” said Alexander Fitz, who joined the company a year ago as engineer for textile technologies and co-ordinator of the Monforts Advanced Technology Centre (ATC). Fitz brings a background in both technical textile technology and processes to the role, having previously worked for a nonwovens machinery builder and a roll-goods manufacturer.

Trials
“We are now looking forward to interesting new trials and pilot production runs, as well as the commissioning of new orders for machines resulting from the extremely busy exhibition,” he says. “Obviously, everyone at the moment is looking to make energy savings, and we have developed a range of options for helping companies increase their resource efficiency, both on new lines and as retrofitted systems, but this is not stifling innovation at the new material level.

“There was a lot of interest in what is possible with the Montex®Coat coating system and the range of different techniques it enables, and at our ATC in Mönchengladbach, a Montex®Coat unit is integrated into the full technical textiles pilot line, on which it is possible to run new fabrics in widths of up to 1.8 metres.”

Explosion proof
The technical textiles line at the ATC incorporates a Montex four-chamber stenter and is fitted with an explosion-proof coating application chamber in order to allow treatment to be carried out with organic solvents and other volatile materials.

Every single component within the chamber has to meet the standards of the European Union’s ATEX directives for working in a potentially explosive atmosphere. A range of sensors linked to alarms operate at various levels within the chamber to ensure the specified lower explosion limit (LOL) is never exceeded and the ventilation adapts accordingly.

Advanced functions
Special features on the finishing line relate to further advanced functions such as the ability to treat materials not only at temperatures of up to 320°C, but also to be able to treat the top and bottom faces of certain materials at different temperatures within a single pass through the machine.

To achieve this, the first two chambers of the stenter are fitted with special, heavy duty TwinAir ventilation motors and separate burners for individual top/bottom temperature. A temperature differential of up to 60°C can be achieved between the upper and lower nozzles within the chamber, depending on the treatment paramenters.

Another key feature of the technical textiles line at the ATC is the special stretching device which is capable of pulling ten tons in length and ten tons in width – a huge amount per square metre of fabric and necessary in the production of materials such as woven or 3D knits for high temperature filter media.

More than 450 participants from 18 countries made in-person connections and gained innovative insights into the segment’s future at the World of Wipes® (WOW) International Conference at the Marriott Marquis in Chicago.

INDA, the Association of the Nonwoven Fabrics Industry, reported strong attendance and activity at its 16th WOW conference, June 27-30. Highlights included a conference, award presentations, a separate 1.5-day WIPES Academy training course, and a new mentorship program.  

WOW speakers focused on the future of the $17 billion wipes sector amid changing consumer trends, supply chain complexities, sustainable packaging demands, and medical disinfection challenges. Program sessions included Circular and Sustainable Wipes, Supply Chain Challenges, Sustainable Substrates, Disinfection Concerns, Sustainable Packaging Trends, and Flushability Developments.

Tony Fragnito welcomed participants in his new role as INDA President for the first time since succeeding Dave Rousse, now President Emeritus and advisor.

WOW highlights included the announcement of Nice’ N CLEAN® SecureFLUSH™ Technology Flushable Wipes from Nice-Pak as the winner of this year’s World of Wipes Innovation Award® for their flushable wipes made of 100 percent cellulose nonwoven. A specialty “lock and key” design of plant-based fibers and formula leverages patent-pending technology to ensure responsible care of plumbing and wastewater.

Other highlights included the presentation of the 2022 INDA Lifetime Technical Award to Richard Knowlson, Principal, RPK Consulting. The award honors an individual with a long-established nonwovens career that advance technology and the commercial success of the North American nonwovens industry. Knowlson pioneered the use of powder super absorbents in airlaid forming systems creating new period product designs for ultra-thin products. He co-founded Airformed Composites, co-invented the first commercial multi-bonded airlaid products in North America that were used in characters for Sesame Street and served in leadership positions with Rayonier, Ciba/Huntsman and Jacob Holm.

Iluna Group is exhibiting at the upcoming Première Vision, from July 5-7, with the aim of promoting a new fashion that combines aesthetic research and environmental responsibility.
 
The key word of this new collection is “experimentation”: the search for new solutions that can offer consumers style, sustainability and well-being translates into innovative blends, natural dyes and smart prints.

This season, the Iluna team is introducing for the first time GOTS-certified organic cotton inside its gallons and allovers, to add a natural touch to its Green Label line. Among the smart ingredients chosen by Iluna Group are Renycle® and Q-Nova, both GRS-certified pre-consumer recycled polyamide yarns, in addition to premium recycled stretch ROICA™ EF by Asahi Kasei. The result is a comfortable and ultralight product that remains true to a high value of creativity and responsibility.

In terms of aesthetic innovation, explorations continue with a yarn blend of FSC-certified viscose and polyamide, resulting in striking new Textronic designs. The 3D effect embossed designs create a cloud effect that, combined with Lurex, shows unexpected glows.

Moreover, the continuous path through the new dimension of responsibility continues in several directions: developments in GRS (Global Recycled Standard) certified recycled yarns aimed at unprecedented effects in both look, performance and hands; experiments with 16 different natural dyestuffs; and continued investment in technologies that can ensure significant savings in water and energy consumption, including GREENDROP, the new GOTS-certified digital pigment printing system.

The 2002 prize of the Walter Reiners Foundation of the VDMA Textile Machinery Association for the best Master's thesis in German textile mechanical engineering was awarded to a young engineer from the ITA Institut für Textiltechnik of RWTH Aachen University. The prize ceremony took place at Techtextil 2022 in Frankfurt am Main, Germany. Peter D. Dornier, Chairman of the Board of the Walter Reiners Foundation, presented the award at the VDMA Textile Machinery Association’s booth.

Felix Xaver Zerbes, M.Sc., was awarded the "Promotional Prize for the Best Master's Thesis of the German Textile Machinery Industry 2022", endowed with 3,500 EUR, for his master's thesis "Development and Construction of a Separation Unit for Weft Yarns in Air Jet Weaving".

The subject of the master's thesis was the development of a mechanism with which faulty sections in the weft yarn can be sorted out before they are woven into the textile. This way, both yarn-related weft defects and material defects can be drastically reduced. The prototype developed by Mr Zerbes shows how this can be done even during the ongoing weaving process without having to stop production. Due to its modular design, the yarn rejection unit can be retrofitted to many different types of air-jet weaving machines, which represents an enormous savings potential not only in Germany but in weaving mills all over the world.

„Nachhaltige Mode macht einen Unterschied. Wir machen einen Unterschied!“ – das waren zwei der wichtigsten Botschaften, die die Community des Neonyt Lab nach drei bunten Veranstaltungstagen unter dem Motto „New Patterns“ in der Union Halle in Frankfurt am Main mitgenommen hat. Die Premiere des Direct to Consumer-Formats besuchten Designer*innen, Aktivist*innen, Konsument*innen und Content Creator*innen sowie Vertreter*innen aus der Modeindustrie aus 22 Ländern.

Am 26. Juni ging das erste Neonyt Lab in Frankfurt am Main zu Ende. Wie in einem Labor konnte man von Freitag, den 24. Juni bis Sonntag in der Union Halle in Frankfurt am Main mit nachhaltiger Mode experimentieren: Sustainable Fashion Styles zusammenstellen und direkt kaufen, in die Nachhaltigkeitsdiskussion eintauchen, sich informieren und vernetzen oder mitmachen und sich mit vielen guten Ideen einbringen. Das Konzept des Neonyt Lab, sich auch für Verbraucher*innen zu öffnen, war neu: Die nachhaltige Fashion-Szene aus insgesamt 22 Ländern, u.a. Deutschland, Österreich, Schweiz, Spanien, Polen, Dänemark, war anwesend. Auf einer Ausstellungs- und Shopping-Fläche von 1.000 m² mit mehr als 30 nachhaltigen Fashion-, Beauty- und Lifestyle-Brands sowie einem umfassenden Event- und Talkprogramm wurde an den drei Veranstaltungstagen viel geboten. Unterstützt wurde des Neonyt Lab von Engagement Global und Oeko-Tex.

Wichtiger Impulsgeber und von den Besucher*innen stark frequentiert waren die zahlreichen Diskussionsrunden, Interviews und Workshops der Fashionsustain, das Konferenzformat des Neonyt Lab. Ein Höhepunkt war die Auszeichnung von Michael Spitzbarth, Founder & CEO von Bleed, als Designer des Jahres für nachhaltige Kollektionen. Der Nachhaltigkeitsaward wird vom VDMD – Netzwerk Deutscher Mode- und Textil-Designer – an Designer*innen verliehen, die sich mit ihren Entwürfen und Kollektionen dem Thema Nachhaltigkeit ganzheitlich verschrieben haben.

Die Verleihung der Förderpreise 2022 der Walter Reiners-Stiftung des VDMA, Fachverband Textilmaschinen an Studierende und Nachwuchsingenieur:innen deutscher Universitäten für Spitzenleistungen im Studium fand am 22. Juni 2022 im Rahmen der Techtextil 2022 in Frankfurt/Main statt. Die bundesweit ausgeschriebenen Förderpreise wurden durch Peter D. Dornier, Vorstandsvorsitzender der Walter Reiners-Stiftung, auf dem VDMA-Messestand verliehen. Zum ersten Mal stand bei der Auswahl der eingereichten Arbeiten der Fokus auf Nachhaltigkeit.
 
Frau M. Sc. Marina Andrea Michel wurde mit dem mit 3.500 EUR dotierten Nachhaltigkeitspreis für die „Beste Masterarbeit des Deutschen Textilmaschinenbaues 2022“ geehrt. Ihre am Institut für Textilmaschinen und Textile Hochleistungswerkstofftechnik der TU Dresden Abschlussarbeit beschäftigt sich mit der „Funktionalisierung von Garnen mittels Cyclodextrinen zur Filtration von Mikro- und Nanoplastik, Übertragung auf Gewebe“.
 
Im Fokus stand ein Verfahren zur textilchemischen Ausrüstung von Garn- und Gewebematerialien aus nachwachsenden Rohstoffen mit Cyclodextrinen, die Mikro- und Nanoplastik (MNP) anbinden. Die grundlegenden Erkenntnisse zeigen dabei das Potenzial daraus hergestellter faserbasierter Filter zur deutlichen und nachhaltigen Minimierung der MNP-Belastung, sowohl von lokalen Trinkwasserquellen bis hin zu globalen Wasserkreisläufen, auf. Die Masterarbeit beinhaltet erstmals die innovative Anwendung von Cyclodextrinmolekülen zur Anbindung kleinster Plastikpartikel unterschiedlicher Form und molekularer Zusammensetzung.
 
Simon Hoebel erhielt den mit 3.000 EUR dotierten Nachhaltigkeitspreis „Beste Forschungsarbeit des Deutschen Textilmaschinenbaues 2022“ über die „Weiterentwicklung des Versuchstandes zur Herstellung von flexiblen hochdrapierbaren Thermoplastfaserbandstrukturen aus recycelten Carbonfasern und Thermoplastfasern für hochbelastbare thermoplastische Verbundbauteile“.
 
Das Ziel der prämierten Forschungsarbeit bestand in der Weiterentwicklung eines Versuchstandes sowie eines anwendungsbezogenen technologischen Knowhows zur Entwicklung und Fertigung von unidirektionalen hochdrapierbaren Thermoplastfaserbandstrukturen aus recycelten Carbonfasern (rCF) und Thermoplastfasern (TFS) für hochbelastbare thermoplastische CFK-Bauteile. Im Rahmen der Forschungsarbeit untersuchte Hoebel den gesamten Prozess zur Herstellung von hochdrapierbaren Thermoplastfaserbandstrukturen von der Kardierung, Verstreckung, Banddoublierung und Konsolidierung. Aus den entwickelten rCF-TFS wurden thermoplastische UD-Verbunde gefertigt und ihre mechanischen Eigenschaften charakterisiert. Die Ergebnisse der Studienarbeit zeigen das Potenzial dieser neuartigen Prozesskette und der darauf basierenden leistungsfähigen und nachhaltigen Thermoplastfaserbandstrukturen auf Basis von rCF.

Am 23. Juni wurde das Atelier Lihotzky im Frankfurter Ostend Schauplatz einer Symbiose von Natur und Technik. Die Neonyt Fashion Show thematisierte mit „Biosphere-Technosphere“ das Zusammenspiel von Mensch und Umwelt; die Elemente Wasser, Luft und Erde im Clash mit unserer industrialisierten, digitalisierten Welt. In 31 Multibrand-Looks und einem multimedialen Runway zeigten rund 50 Brands die Zukunft der (nachhaltigen) Mode.

Der Fokus der Neonyt Fashion Show lag auf der Verbindung von Natur und ihren Elementen Wasser, Luft und Erde mit allem, was Menschen erschaffen – von Infrastruktur über Architektur, der industriellen Landwirtschaft und der digitalen Welt. Die Kombination dieser scheinbar kontroversen Themen spannte den Bogen zu unserem gegenwärtigen Erdzeitalter, dem Anthropozän, in dem der Mensch zu einem der wichtigsten Einflussfaktoren auf die biologischen, geologischen und atmosphärischen Vorgänge auf der Erde geworden ist.

Neue Dimensionen und regenerative Systeme
Die Biosphäre wurde vor allem durch die Silhouetten und Strukturen in den Looks repräsentiert, wie auch durch die organischen und regenerativen Materialien, aus denen ein Großteil der Kollektionsteile gefertigt wurde. So werden auf der Neonyt Fashion Show biologisch angebaute oder nachhaltigere regenerative Materialien zugelassen, die dazu beitragen, wertvolle Ressourcen wie sauberes Wasser, Energie und Land zu schützen und damit zu einem gesunden Ökosystem beitragen.

Die Technosphäre, zu der qua Definition auch die Menschen gehören, wurde in der Inszenierung über die Verschmelzung von der digitalen Welt mit der realen Welt über große LED Screens dargestellt, auf denen digitaler Content sowie Close-ups und Überblendungen der gezeigten Looks zu sehen waren. In den Kollektionen manifestiert sich die Technosphäre in den Themen Recycling bzw. recycelte Chemiefasern, sauberer Chemikalieneinsatz oder im technischen Kreislauf des Cradle2Cradle-Konzepts. Visuell stellte sich die Technosphäre in glänzenden und reflektierenden Oberflächen dar sowie in Sportswear- und Outdoor Styles.

Insgesamt zeigten ca. 50 Brands in 31 Looks eine Bandbreite von etablierten Marken und upcoming Avantgarde Brands: Ai Komoto, Akjumii, Andy Wolf, Anna Auras, Antje Pugnat, Arys, Ayede, Catalouge of Disguise by Tanja Bombach, Céline Breton, Chika Takahashi, Clean Waves, Damur, Ecoalf, Fade Out Label, Falke, Florentina Leitner, Good Guys Don’t Wear Leather, Hell Hell Studio, KC Dubbick, Lanius, Laura Gerte, Maison Baum, Maximilian Mogg, MCM x Selassie, Muntinøus by Pino Pipoli, Myfassbender, Nat-2, Neubau, Nightboutique, PB 0110, Plas Collective, Pool Berlin, Provincia Studio, Save the Duck x Edward Crutchley, Souvenir Official x Ajobyajo, Spaccio Maglieria, Spatz Hutdesign, Timberland, Tiziano Guardini, Tizz & Tonic, Trakatan, Tribal Hotel, Trippen, Tuuli-Tytti Koivula, Uncommon Matters, Virginia Evangelista, Virón, Vitelli, Vladimir Karaleev und Wunderwerk.

Zum Publikum zählten Personen aus Wirtschaft und Politik sowie Industrie-Insider*innen aus der Mode- und Nachhaltigkeitsbranche. Einkäufer*innen, Designer*innen, Künstler*innen waren gleichermaßen anwesend wie (inter-)nationale Fachpresse, Tageszeitungen, Modezeitschriften, Content Creator*innen, TV und Hörfunk. Auch waren Aktivist*innen von Fashion Revolution und Vertreter*innen des Fashion Impact Fund vor Ort.

The viscose specialities manufacturer Kelheim Fibres has won the Techtextil Award in the "New Concept" category for their project "Cellulose-based nonwovens for highly absorbent reusable products".
This award is intended to make cutting-edge developments visible, promote unconventional thinking and intensify the dialogue between researchers, manufacturers.

The starting point for the innovation was the search for a washable and thus reusable absorbent pad made of completely bio-based materials for the cloth diaper of the Berlin-based start-up Sumo.
Two main requirements of the application are obvious: A fast and efficient liquid distribution and high absorbency should minimise rewetting and leakage. Both are ensured by speciality viscose fibres from Kelheim, which have been making this essential contribution to absorbent hygiene products such as tampons for many years. The obvious solution was therefore to optimally utilise the synergies between knitted and woven structures with nonwovens.

In doing so, the advantages of nonwovens in combination with speciality viscose fibres in terms of absorbency (through e.g. more open-pored structures) have been perfectly transferred from the field of disposable to the world of reusable products. For reusable products, however, there is another challenge to overcome: they must remain stable during washing and over several cycles of use. To ensure this, an innovative nonwoven construction was developed in close cooperation with the STFI. These nonwovens can be used as a stand-alone solution or integrated into a textile structure.
