From the Sector

With the next generation of soft and stretchable electronics, reproducible and stretchable conductive inks are playing an increasingly important role in areas such as smart textiles, medical textiles or wearables. Saralon produces a range of stretchable conductive inks including Saral StretchSilver 500 for e-textile applications.

While electronic applications integrated into textiles gain popularity, printed stretchable conductive inks emerge as a transformative alternative for the complicated approach of weaving conductive yarns and fibres.

Just like choosing the right fabric and additives is vital for smart textile development, selecting the right conductive ink matters too. There are challenges to consider, such as conductivity, ink penetration into the fabric, changes in physical properties most importantly stretchability, printing process controllability, and reproducibility. That's why research and analysis are essential when deciding on the best conductive ink for a project.

Together with the Saxon Textile Research Institute e.V. (STFI) Saralon conducted some performance tests benchmarking our Saral StretchSilver Ink against some competitor product.

Results:
Conductivity:
Saral StretchSilver 500 consistently demonstrated superior conductivity, regardless of line width.

Fluctuations at lower widths:
Both inks exhibited fluctuations at narrower printed lines, but the Alternative Ink displayed significantly higher variations.

Reproducibility Insights:
Saral StretchSilver 500 maintained stable resistance at 2mm and beyond, while the Alternative Ink noticeably struggled.

Elongation behaviour:
Saral StretchSilver 500 harmoniously coexists with the textile. Its application has minimal impact on the fabric's stretching properties, ensuring stability. The Alternative Ink, on the other hand, leads to significant changes in textile’s elongation properties. With this ink, stretching demands considerably higher forces.

Polyurethane has become an integral part of our daily lives, whether in the construction industry, in leisure activities, in the manufacture of furniture or in numerous other applications. The precision gear pumps from Oerlikon Barmag, which will be presented at this year's UTECH Asia / PU China 2024 in Shanghai, impress with customised solutions for demanding tasks in the chemical industry. They increase the productivity of the often complex manufacturing processes for this wide range of applications.

Oerlikon Barmag pumps handle demanding processes in PUR applications, in the chemical, plastics or paint and lacquers industries. One of the greatest challenges lies in the accurate and reliable metering of toxic or low-viscosity media. With the GM and GA series and the associated components, Oerlikon Barmag presents the optimum equipment for these applications.

GM pump
Pumps in the GM series achieve precise dosing by feeding the flow with low pulsation. The multi-stage GM pump conveys low-viscosity media even under high pressure and the most difficult operating conditions (e.g. 250 bar, 100 mPas). The standard pump for many dosing tasks is the GM series in a square design. With the development of the multi-stage pump, the range of applications for the GM series has been significantly expanded. The round 2-stage GM pump has been specially developed for use in high-pressure technology. It fulfils the special challenge of pumping small flow rates with low viscosities. The pump serves flow rates from 0.05 to 20 ccm/rev and is therefore particularly suitable for the production of PUR moulded parts, block foam, refrigeration unit insulation or sandwich panels.  

GA series
Making products and processes more efficient is a constant challenge for manufacturing companies. This is why Oerlikon Barmag has added the GA series to the GM series especially for the demanding conveying of high-viscosity media. The GA series is available in delivery volumes of 1.25 - 30 cm³/rev (0.6-144 l/h). It is designed for pressures up to 200 bar, for viscosities up to 1,500 Pas and for temperatures up to a maximum of 225°C. With this pump series, Oerlikon Barmag offers customised solutions for process engineering processes where highly accurate and uniform metering is required.

The drum pump
The drum pump from Oerlikon Barmag is specially designed for conveying and dosing highly viscous materials such as adhesives, silicones and other highly viscous materials from drums and other large containers and for pressures of up to 250 bar. One of its special features is not only that it discharges highly viscous materials from the drum, but also that the medium can be dosed directly without an intermediate stop.

The gear pump and drum follower plate are synchronised so that the plate effortlessly reaches the bottom of the container, leaving behind only a very small residual quantity of < 1%. This reduces material costs and has a positive effect on the production process.

From June 24 to 28, a delegation of Italian textile machinery manufacturers will be engaged in Turkmenistan for an institutional mission organized by ACIMIT, the Association of Italian Textile Machinery Manufacturers, and Italian Trade Agency. The delegation will have some institutional and commercial meetings scheduled in Ashgabat.

For the Italian textile machinery industry, the Turkmen market has high growth potential. Cotton is the third largest export product of the Country, and local authorities aim to develop a robust textile industry capable of processing the locally grown raw material. Significant investments in new equipment will be necessary for the success of this development program. To achieve this goal, the demand for textile machinery and technologies is rapidly increasing.

This is testified by the average annual growth rate of Turkmen textile machinery imports between 2009 and 2023 (+7.3%). Furthermore in 2024-2027 period forecasts by ACIMIT predict a further average annual increase of 5.5%.

Meanwhile, in 2023, the demand for Italian textile machinery from Turkmen companies has grown. Italian exports increased from 600,000 euros in 2022 to approximately 13 million euros the following year.

The Italian companies participating in the institutional mission are: Brazzoli, Color Service, Itema, Marzoli, Mcs, Reggiani Macchine, Salvadè, Santoni.

Archroma is bringing its new SUPER SYSTEMS+ concept and key denim innovations to Denim Première Vision Milan on June 5 and 6 and Denimsandjeans Vietnam on June 26 and 27.

From classic blue jeans to fashion-forward designs with fresh cuts, colors and finishes, denim remains one of the most popular fabrics worldwide. At the same time, the industry is beginning to question traditional production methods that use considerable water and energy and also have limitations in terms of the selection of chemicals and dyes that are clean and safe.

Archroma will demonstrate its solutions at Denim Première Vision Milan and Denimsandjeans Vietnam, including SUPER SYSTEMS+ for Denim. SUPER SYSTEMS+ are end-to-end systems developed by Archroma to allow brands and mills to make an impact by saving resources, delivering more durable apparel or adopting cleaner chemistries, or by choosing enhanced outcomes in all three areas at once. The suite encompasses wet processing solutions from sizing to finishing; durable colors and functional effects that add value; and cleaner chemistries that go beyond compliance to anticipate future restrictions.

Trade show visitors will also be able to explore Archroma’s new DENIM HALO, a laser-friendly and easy washable denim, as well as a range of other product innovations, such as DIRESUL® EVOLUTION BLACK, DENISOL® PURE INDIGO 30 and EarthColors®.

DIRESUL® EVOLUTION BLACK is Archroma’s cleanest sulfur black dyestuff. Manufactured using fewer resources, it has an overall impact reduction to 57% during dye synthesis compared to standard Sulfur Black 1 liquid.* Importantly, it also offers mills the opportunity to deliver unique shade and wash-down effects that stand out in the market.

DENISOL® PURE INDIGO 30 LIQ is an aniline-free** pre-reduced indigo that creates authentic denim look with the same performance and efficiency as conventional indigo dye, but in a way that can reduce the risk of pollution. Furthermore, it is produced in an aniline-free** process to help enable cleaner denim production.

EarthColors® is a patented Archroma technology that creates high-performance biowaste-based dyes from non-edible food and agricultural waste, leaving the edible part available for consumption. EarthColors® dyes are fully traceable and help reduce the industry’s overall impact on the water footprint. Since they upcycle waste from other industries, they also help contribute to a circular economy.

Molotowcocktailschutzanzug – textiler Schutzanzug für Polizeieinsatzkräfte zum Schutz vor Molotowcocktails
Spezialeinsatzkräfte sind auf Schutzkleidung angewiesen, die vor vielfältigen Gefahren schützt. Meist schränkt eine höhere Schutzwirkung den Tragekomfort ein. Forscher des STFI und des ITA Aachen haben daher gemeinsam ein hitzebeständiges Gewebe entwickelt, das vor Angriffen mit Molotowcocktails schützt und dabei gleichzeitig einen hohen Tragekomfort gewährt. Molotowcocktails können schwerwiegende Verletzungen hervorrufen, die es zu verhindern gilt. Das Verletzungspotential hängt insbesondere mit der extrem hohen Verbrennungstemperatur von 800 °C – 1.700 °C zusammen, aber auch der starken adhäsiven Wirkung der Brandsätze. Die entwickelte Schutzkleidung zeichnet sich durch eine optimierte Faserzusammensetzung sowie durch eine spezielle Garn- und Gewebekonstruktion aus. Dar-über hinaus wurde die Funktionalisierung des Gewebes angepasst.

Holz/Textil-Faltwerke
Im abgeschlossenen Projekt wurden Holz-Textil-Faltwerken (HTF) entwickelt, die temporär zum Zweck des Schallschutzes, Sichtschutzes oder der räumlichen Abgrenzung aufstellbar sind. Unter Nutzung der Origami-Mathematik wurden mehrschichtige Holz-Textil-Verbunde entwickelt. Das Textil dient als zweidimensionales Scharnier der fertigen Konstruktion. Durch den Verbund aus biegeschlaffen textilen Materialien mit biegesteifen Holzelementen sind Faltbewegungen möglich, die eine selbsttragende Struktur entstehen lassen. Die HTF zeichnen sich durch kleines Packvolumen und Leichtbauweise aus. Gezeigt wird ein Tischmodell des Demonstrators.

Graviola
In der Naturmedizin werden die Blätter des tropischen Graviola-Baumes (Annona muricata) zur Verbesserung des Wohlbefindens und zur Behandlung zahlreicher Krankheiten eingesetzt. Die Wirkung der Graviolapflanze ist hauptsächlich auf die enthaltenen aktiven Wirkstoffe der Acetogenine zurückzuführen. Ziel des Projektes GRAVIOLA war die Entwicklung neuartig funktionalisierter Textilien, die mit Wirkstoffen der Graviolapflanze ausgerüstet sind. Gezeigt werden auf dem internationalen Pavillon des Innovationstag Mittelstand mit Graviola ausgerüstete Textilmuster auf Basis von Wirkstoffverkapselungen und Graviolaextrakten.

INTAKE – Entwicklung und Erprobung intelligenter Einbringungstechnologie für Datenkerne in der Wäschekonfektionierung
Im Projekt INTAKE haben sich aktuell sechs Forschungspartner das Ziel gesetzt, ein KI-gesteuertes Verfahren zu entwickeln, das RFID-Antennenfäden und -Chips während des Konfektionsprozesses in die Wäsche einbringt und so die Notwendigkeit des nachträglichen Patchens eliminiert. Die Wäsche selbst wird so zu einem individuell funktionalisierten RFID-Transponder gemacht. Gezeigt wird Flachwäsche wie z.B. Bettlaken oder Kopfkissen mit integrierter kleindimensionaler RFID-Fadentechnologie inkl. Datenkern und Textilantenne für eine gesteuerte Einbringung per KI und zukünftige Leasing-Szenarien

Die Multimatt ist eine Spielmatte, welche unterschiedliche Fertigungs- und Veredlungstechnologien unter Verwendung eines rezyklierten und Cradle to Cradle-zertifizierten Materials zu einem kreislauffähigen Produkt vereint. Die entwickelte MultiMatt verbindet den Monomaterial-Ansatz mit dem Flächenbildungsverfahren Stricken und den Veredlungs- und Funktionalisierungstechnologien 3D-Druck, Rückenbeschichtung und Laserbehandlung. Damit ist die Entwicklung zur Anwendung für nachhaltiges Design, kreislauffähige Materialverbunde und Rezyklate geeignet.

Multiple global regulations set to take effect in the coming years have made traceability an imperative for retailers and brands. These include the Digital Product Passport, the Corporate Sustainability Due Diligence Directive, and the New York Fashion Sustainability and Social Accountability Act, to name a few.

While companies are aware of the importance of traceability, research indicates that they are not prepared to comply with upcoming legislation. A recent KPMG survey highlighted that 43% of executives at major enterprises had no visibility or were “largely unclear” about the performance of their Tier 1 suppliers. At the same time, only 28% of companies had clear visibility into Tier 2 suppliers.

TradeBeyond’s recently published Supply Chain Traceability Guide, the latest installment of its Retail Sourcing Report series, highlights the myriad challenges that companies face in implementing effective traceability programs. This report is relevant for all industries, and is especially topical for the apparel and footwear sectors, which are under increasing scrutiny to enhance traceability to ensure sustainability.

The report highlights retail’s slow progress in achieving transparency, as evidenced by the Fashion Transparency Index, which found that the average transparency score across 250 of the world’s largest brands and retailers was just 23%. That suggests that progress on transparent disclosure of social and environmental data is still lagging.
 
The report shows that brands fall short on most key measures of sustainability and traceability, including publishing a responsible code of conduct and providing visibility into their Scope 3 carbon footprint. The United Nations Economics Commission found that only a third of the top one hundred global clothing companies track their own supply chains. One of the obstacles is complexity. More than two-thirds (69%) of fashion companies report that complexity of their global business networks is an obstacle to visibility.

In addition to a lack of visibility, false sustainability claims are also rampant. Greenpeace found that in the apparel and footwear sector, 39% of sustainability claims are false or deceptive. Lack of third-party verification of ESG measures is also rampant.

The highest scoring brands in the 2023 Fashion Transparency Index included luxury brands such as Gucci and retailers such Target Australia, Kmart Australia, OVS, and Benetton. These companies back up their commitment with solid action on multiple measures of traceability.

Along with legislative requirements, consumers are a key driving force pushing companies to improve their traceability initiatives. McKinsey research found that 66% of consumers consider transparency to be a key factor when making a purchase decision and 73% of consumers would pay more for products with transparency into production and sourcing.

The report also highlights key challenges to overcome in the journey to traceability, including effective communication between stakeholders, compliance with new regulations, technology barriers, and data complexity.

On the positive side, the industry is responding with sophisticated technology, including software systems that incorporate artificial intelligence and blockchain-enabled traceability, which provide the required visibility and compliance.

Traceable fiber technology, which allows for traceability from the material origin of a product until its end-life, provides the option of a “fiber-forward” rather than a “product backward” approach to achieving traceability.

Aside from the regulatory and consumer drivers, there is a strong business case for implementing traceability, which includes cost savings, operational efficiency, brand protection and reducing supply chain risk. As such, TradeBeyond expects a rapid evolution in traceability programs across industries, especially in those that lag in best-practices.

While there has been considerable progress in recent years toward accurately tracing the complete origins of products, much more needs to be done. Brands and retailers must intensify their efforts to stay compliant with escalating regulations and align with evolving consumer preferences.

Teijin Frontier Co., Ltd., the Teijin Group’s fibers and products converting company, announced the development of a new, multifunctional and comfortable polyester material that combines high breathability and UV protection. This new product reproduces the structure of a traditional Japanese "Sudare" blind (bamboo blind), which allows breezes to pass through while blocking out sunlight.

As extremely high summer temperatures become increasingly common, Teijin Frontier developed this new polyester to meet market demands for materials with enhanced heat protection functions. Heat protection encompasses breathability, UV resistance and anti-stickiness. However, until now, breathability – achieved by gaps between fibers – and UV protection were thought to be mutually exclusive.

To solve this dilemma, the company created a structure with slit-shaped, highly breathable areas in either the warp or weft direction of the fabric. These three-dimensional gaps, similar to those in a bamboo blind, allow the material to deliver both excellent breathability and high UV blocking performance of 85 percent or more. The structure allows air permeability of 50㎤/㎠・s or more.

This new product also offers sustainability benefits through the incorporation of recycled polyester in part. Its structure and elastic fibers provide stretch performance, while an uneven surface caused by differences in thread shrinkage and its structure avoid stickiness. Moreover, to achieve the combination of functions, Teijin Frontier also adopt special high-shrinkage technology and dying finishing technology. This material offers potential for use in both fashion and casual clothing.

Teijin Frontier will begin promoting this product for the 2025 spring and summer fashion and casual clothing collections in Japan, aiming for sales of 250,000 meters in fiscal 2024 and 750,000 meters in fiscal 2027.

KM.ON launches its new Quality Monitoring System (QMS) for the retrofit market at ITM from June 4 to 8 in Istanbul, presenting a solution for quality management on warp knitting machines.
For its performance in defect detection, the QMS uses the advances of our time: a camera system that captures images of the production process, and a specialized artificial intelligence (AI) to analyze the images. Particularly in terms of handling, reliability and precision of defect detection, the QMS from KM.ON offers advantages over conventional systems that do not rely on AI analysis.

The QMS is designed for easy setup and can be operated without prior expertise. If a defect causes the machine to come to a standstill, the operator is informed immediately via a user-friendly interface. The immediate warning enables rapid intervention and therefore less downtime and more productivity.

Thanks to its conceptual design, the QMS only stops production when actual defects are detected. Unnecessary interruptions caused by external disruptive factors, such as changing light conditions, are avoided. This precision prevents productivity losses and helps to ensure continuous operation. Costs due to unnecessary machine downtime are avoided.

Unlike conventional camera systems, the QMS detects even the most complex defects and triggers an immediate machine stop. This minimizes material waste. During operation, the AI-controlled system learns from the data to enhance its detection accuracy, thereby reducing the reject rate and costs. The QMS also adapts to evolving production environments to ensure consistently high efficiency.

Der Bundesverband Medizintechnologie (BVMed) hat die Initiative von Bundeskanzler Olaf Scholz und Präsident Emmanuel Macron begrüßt, den EU-Haushalt neu auszurichten und „mehr für die Wettbewerbsfähigkeit ihrer Industrie“ zu tun. Dafür soll Bürokratie ab- und Schlüsseltechnologien ausgebaut werden. „Die MedTech-Branche ist in Europa eine Schlüsseltechnologie der Zukunft, die auch noch entscheidend für die Gesundheit und Lebensqualität der Menschen ist. Wir können gerade hier die Chancen noch besser nutzen, bessere Anreize für Innovationen setzen und unnötige Bürokratie abbauen. Wir müssen mit einem ‚Industrial Deal‘ einen besseren Interessensausgleich mit wirtschaftspolitischen Belangen erreichen und Europa wieder wettbewerbsfähiger machen“, kommentiert BVMed-Geschäftsführer und Vorstandsmitglied Dr. Marc-Pierre Möll.

• Der europäische Markt für Medizintechnik beträgt insgesamt rund 160 Milliarden Euro. Das sind über ein Viertel des Weltmarkts. Europa ist damit nach den USA der zweitgrößte MedTech-Markt der Welt.
• Die 35.000 europäischen MedTech-Unternehmen investieren viel in die Verbesserung und Entwicklung bahnbrechender Technologien zum Wohle der Patienten und beschäftigen 865.000 Menschen in Europa.
• 92 Prozent der Unternehmen sind kleine und mittelständische Betriebe (KMU).

Insbesondere hilft die Medizintechnik den Patient:innen und unterstützt die Angehörigen der Gesundheitsberufe mit innovativen Lösungen. Sie sorgt dafür, dass immer mehr Menschen besser und gesünder länger leben.

„Aber: Europa verliert bei dieser wichtigen Schlüsselindustrie durch die überbürokratische und nicht praxistaugliche europäische Medizinprodukte-Verordnung, kurz MDR, den Anschluss“, warnt Möll. Unternehmen bevorzugen mittlerweile die Markteinführung von Innovationen in den USA.

• Nach einer Analyse der Boston Consulting Group (BCG) priorisieren mittlerweile 89 Prozent der Unternehmen eine FDA-Zulassung.
• Auch die BVMed-Herbstumfrage 2023 zeigt: Die Zeiten, in denen das europäische Regulierungssystem für Medizinprodukte dem US-amerikanischen FDA-System überlegen war, sind lange vorbei. 53 Prozent der BVMed-Mitgliedsunternehmen präferieren das FDA-System, nur 12 Prozent das MDR-System der EU. 35 Prozent haben keine Präferenz.

In seinem MDR-Whitepaper fordert der BVMed daher unter anderem die Abschaffung der fünfjährigen Re-Zertifizierungs-Pflicht, die Einführung eines Fast-Track-Verfahrens für innovative Produkte, Orphan Devices und Nischenprodukte, die Steigerung der Effizienz, der Transparenz und der Berechenbarkeit des MDR-Systems sowie die Zusammenführung der Verantwortung im System über eine zu schaffende Governance-Struktur.

Der BVMed fordert in seinem Positionspapier zur Europawahl am 9. Juni 2024 zudem einen eigenen Gesundheitsausschuss im Europäischen Parlament, um den gestiegenen Stellenwert der Gesundheitsthemen abzubilden. Unter dem Titel „Medizintechnik-Standort Europa stärken“ ist es für den deutschen Medizintechnik-Verband besonders wichtig, die Resilienz des Gesundheitssystems zu stärken und damit die medizinische Versorgung krisenfest zu gestalten.
