From the Sector

Techtextil India is scheduled to take place between 12 – 14 September, 2023 in Mumbai. The continued support from the Ministry of Textiles demonstrates the huge emphasis laid for this key sector in boosting the economy of the country given the enormous scope to grow rapidly apart from the remarkable opportunities present to do business in India.
 
Techtextil India is the country’s leading trade fair on technical textiles, non-wovens, fibres, yarns and machinery. With almost eight months to go, the three-day business event has received an overwhelming response from various companies who will be seen showcasing their latest solutions and products for key application areas.
 
Commenting on the developments, Mr Raj Manek, Executive Director and Board Member, Messe Frankfurt Asia Holdings Ltd, shared: “We are elated to have received the support from the Ministry of Textiles, Government of India and believe that it will bring in strong value to the technical textiles segment of our trade fair while opening doors to lucrative business engagements for the industry. We are optimistic that it will gain for us a wider reach and increase our credibility among the industry.”
 
The last edition of Techtextil India in November 2021 emerged as a crucial meeting place for the technical textile players. Even though the show happened to be the first post lockdown edition it garnered an attendance of 4,087 visitors due to live demonstration of latest products and technologies from over 150 technical textile brands.

Freudenberg Performance Materials announces the launch of Filtura, its new product brand for filter media solutions. Filtura is a comprehensive portfolio of innovative high-performance filter media products and customized solutions for air and liquid filtration. The company is debuting Filtura at Filtech, the international trade fair for the filtration technology industry, in Cologne in February 2023.

Freudenberg Performance Materials’ established Colback®, Enka®solutions, Evolon®, Karbofil and Lutradur® brands are being brought together under the Filtura brand. With the new brand, the specialist for technical textiles is pooling its know-how more effectively across products lines and giving innovations for the filter media market a further boost. Filtura will enable Freudenberg Performance Materials to extend its position in this market.

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.

Hologenix®, creators of CELLIANT®, is pleased to announce CELLIANT® with REPREVE® – introduced with global textile solutions provider UNIFI®, makers of REPREVE® – has been awarded a Selection in the Fibers & Insulation Category of ISPO Textrends Fall/Winter 2024/25.

Twice a year, ISPO recognizes innovative fibers, fabrics and components that are used to manufacture sports apparel. Both companies are excited that CELLIANT® with REPREVE®, whereby CELLIANT infrared (IR) technology is embedded into REPREVE, a brand of recycled fiber, has achieved the honor. CELLIANT® with REPREVE® is a performance fiber made from recycled materials that have been enhanced with IR technology to provide wellness benefits to the consumer.

CELLIANT is a natural blend of IR-generating bioceramic minerals, which, when embedded into textiles, allows them to convert body heat into infrared energy, returning it to the body and temporarily increasing local circulation and cellular oxygenation. This aids significantly in muscle recovery, increases endurance, and improves overall performance in healthy individuals, among other benefits.

REPREVE recycled performance fiber consists of high-quality fibers made from 100% recycled materials, including post-consumer plastic bottles and pre-consumer waste. It is also certified and traceable with UNIFI’s U TRUST® verification and FiberPrint™ technology, which provide assurance that the product comes from recycled materials. Compared to virgin fiber, REPREVE helps to offset the use of petroleum, conserving water and energy and emitting fewer greenhouse gasses.

This award marks the third year in a row that Hologenix has had its CELLIANT technology recognized in the Fall/Winter Textrends Awards. CELLIANT in pure white was a Top Ten Winner in last year’s awards. The prior year, CELLIANT Viscose was a Selection Winner as well.

Under the motto “People Matter” A+A 2023, a Trade Fair for Safety, Security and Health at Work, will revolve around the most important trends of our time: sustainability and digitalisation. Here, exoskeletons also play a prominent role as tomorrow’s ergonomic tools. An important conference in this field is WearRAcon Europe which will be held at A+A from 25 – 26 October 2023 for the first time.

The Conference will be organised by the Fraunhofer Institute IPA in cooperation with the Stuttgart University and the Wearable Robotics Association (WearRA). The 38th A+A Congress, which is held by Bundesarbeitsgemeinschaft für Sicherheit und Gesundheit bei der Arbeit (German Federal Association for Occupational Safety and Health - Basi) will be closely dovetailed thematically and in terms of content with it.

Being able to walk again despite a serious injury, handle heavy parts without outside help or simply do overhead work comfortably and for extended periods of time - the advantages of exoskeletons have already convinced numerous industries. Exoskeletons and wearables are now already being used successfully in industry and commerce, and major machine builders and automakers as well as the medical sector are continuing to experiment with man-machine connections. Currently, the global market volume for exoskeletons is valued by leading analysts at over US$20 billion by 2030.¹

The WearRAcon Europe Conference 2023 will provide new insights into the promising world of exoskeleton systems from different perspectives and, in conjunction with the A+A Congress, set future-oriented impulses. Lectures by renowned exoskeleton pioneers combined with testimonials presented by users from a variety of industries and keynotes by experts will round off the programme. And, like at the previous A+A, a Self-Experience Space will again be set up so that the exoskeleton systems of various manufacturers can be tested in realistic work scenarios.

In parallel with the Self-Experience Space, the large live study Exoworkathlon will also take place again. Trainees from various mechatronic training courses have to complete a concourse and perform holding, lifting and assembling tasks, which have been specially developed with the industry. Data is prospectively collected with different measuring sensors to measure the effects of exoskeletons. In the Exoworkathlon, the IPA focuses especially on prevention for young employees in order to raise awareness of the issue and counteract ailments at an early stage.

• Award for near-net-shape 3D meshes for use in fibre-reinforced plastics

As part of the JEC FORUM DACH 2022, the AVK Innovation Awards were presented in Augsburg on November 29th. The innovation price in the category "Research/Science" (first place) was awarded to the team of scientists Dipl.-Ing. Dominik Nuss, Dr.-Ing. Cornelia Sennewald and Prof. Dr.-Ing. habil. Chokri Cherif.

With the development of the pull-off-free Jacquard weaving technology including the technological know-how in the field of highly complex 2D and 3D fabric geometries, which has been established at the ITM of the TU Dresden for many years, Dominik Nuss has succeeded in including different yarn lengths locally into the fabric structure solely through targeted variation of the fabric weave. There-fore, it is now possible to produce completely new types of fabrics without additional draping, especially spherically curved fabrics, but also large-format spiral or even curved fabrics. The fact that the required near-net-shape geometry of the component to be reinforced can be reproduced with significantly reduced preforming steps is to be emphasized.

Continuous simulation aided engineering from CAD design to integrally woven 2D and 3D preforms by means of highly complex weave development for spatial constructions is a unique at the ITM, which was indispensable for the development of these promising woven high-tech structures. This technology is completely new and has never been carried out in this way before. The fabric structures are characterised by a high innovation level due to their geometric diversity and purposes. It can be used in numerous applications and further more contributes to the development of completely new fields of application. The technology can be implemented on all Jacquard weaving machines with only an additional device and the preform geometry is only determined by the control of the Jacquard machine. The preform geometry can be used in the full working width of the weaving machine.

Professor Chokri Cherif, Institute Director of the ITM, and his team are very pleased about these continuous research success in the constantly growing research field of 3D weaving technology, which are achieved at the ITM in close cooperation with industry and users. "This award is a special honour for our institute and confirms that the many years of our excellent research in the field of near-net-shape 3D weaving for the fibre-reinforced plastics sector plays a significant role and that we are making a significant contribution to the sustainable and resource-efficient production of lightweight structures with our development".

RecyOuest, France, has successfully started up the world's first recycling line for agricultural plastic waste nets at its mill in Argentan. The innovative recycling line featuring a unique dry-cleaning system was delivered, installed and commissioned by the international technology group ANDRITZ in August 2022.

RecyOuest, based in Argentan, France, is a green economy company that handles the recycling contaminated filamentary thermoplastics such as round bale nets and twines. With its recycling process, RecyOuest is part of a circular economy approach.

The ANDRITZ recycling line can process up to 8,000 tons of waste and produce recycling fibers for nonwoven applications and also for pellets made of waste from agricultural single-use plastic nets and twines. These pellets are then returned to the plastics industry by mixing both recycled and virgin raw materials, thus reducing the amount of virgin plastic used.

This line, inspired by the techniques from textile wastes recycling, is equipped with a unique mechanical dry-cleaning system that allows resource savings by avoiding the use of water and chemicals. This state-of-the-art ANDRITZ equipment allows RecyOuest to produce recycling fibers for nonwoven applications and also pellets for ever new eco-designed nets and twines for the agricultural sector, with the lowest possible environmental impact.

BVMed: „Masken müssen korrekt angewendet werden“

Nur 10 Prozent der Deutschen wechseln ihre FFP2-Maske nach jedem Gebrauch. 9 Prozent der Bevölkerung wechseln die Maske so selten wie möglich, über 18 Prozent tragen überhaupt keine Maske. Das ergab eine repräsentative Befragung des Meinungsforschungsunternehmens Civey im Auftrag des Bundesverbandes Medizintechnologie (BVMed). 2.500 Personen wurden zwischen dem 28. und 29. November 2022 befragt. Die Ergebnisse sind repräsentativ für die Einwohner Deutschlands ab 18 Jahren. Der statistische Fehler der Gesamtergebnisse liegt bei 3,3 Prozent.

„Medizinische Masken schützen bei richtiger Anwendung sehr gut vor Infektionen. Wichtig ist, die Hinweise der Profis zum richtigen Umgang mit Masken und die Hygieneregeln zu beachten“, kommentiert BVMed-Geschäftsführer und Vorstandsmitglied Dr. Marc-Pierre Möll.

In Teilen des öffentlichen Raumes gilt weiterhin die Pflicht zum Tragen einer medizinischen bzw. einer FFP2-Maske. Nach der BVMed-Umfrage sind die häufigsten Wechselgründe: Wenn die Maske verschmutzt ist (50,8 Prozent), kaputt gegangen ist (41,3 Prozent), schlecht riecht bzw. unhygienisch ist (37,0 Prozent) oder wenn die Maske durchfeuchtet ist (35,6 Prozent).

Unterschieden werden OP-Masken bzw. medizinische Masken (Mund-Nasen-Schutz) und Atemschutzmasken.

• OP-Masken dienen vor allem dem Schutz der Umgebung vor Keimen, die Träger:innen beispielsweise durch Atmen oder Niesen verteilen könnte.
• Atemschutzmasken hingegen dienen dem Schutz der Träger:innen vor Viren. Bei den Atemschutzmasken gibt es wiederum verschiedene Gruppen. Zum Schutz vor Viren und Mikroorganismen sind grundsätzlich Masken mit einem Partikelfilter geeignet. Dazu zählen unter anderem sogenannte Partikelfiltrierende Halbmasken, besser bekannt als FFP-Masken.

Genutzt werden von den Menschen aktuell vor allem FFP2-Masken. Sie sind nur dann wirksam, wenn sie korrekt angelegt werden.

• Vor dem Aufsetzen der Maske sollten die Hände gründlich mit Wasser und Seife oder einem geeigneten Desinfektionsmittel gereinigt werden.
• Die Maske muss gemäß der ihr beiliegenden Anleitung aufgesetzt werden. Sie muss Mund und Nase vollständig abdecken.
• Es muss sichergestellt sein, dass keine Lücken zwischen Gesicht und Maske vorhanden sind.
• FFP2-Masken sollten grundsätzlich nicht mehrfach verwendet werden, da es sich i.d.R. um Einmalprodukte handelt.
