From the Sector

Im Rahmen eines neuen Projektes des Spitzenclusters Industrielle Innovationen (SPIN) entsteht eine offene Versuchsplattform für die Entwicklung von Power-to-X-Technologien. Untersucht werden dabei Möglichkeiten, CO2-haltige Abgasströme zunächst in ein Synthesegas aus Kohlenmonoxid und Wasserstoff und dann in verschiedene Produkte für die Chemie-, Kraftstoff- und Kunststoffindustrie umzuwandeln. Die nordrhein-westfälische Landesregierung fördert dieses Vorhaben mit 5,3 Mio. Euro.

Die Federführung des Projektes »PtX-Plattform« liegt bei der Mitsubishi Power Europe GmbH. Gemeinsam mit SPIN sowie den Projektpartnern – dem Fraunhofer UMSICHT, dem Lehrstuhl für Umweltverfahrenstechnik und Anlagentechnik (LUAT) der Universität Duisburg-Essen sowie Evonik Industries – will das Unternehmen marktfähige Lösungen für die effiziente Nutzung überschüssigen Stroms entwickeln. Ein Schwerpunkt werden dabei Wasserstoff- sowie Carbon-Capture-Use-and-Storage-Technologien sein: CCU und CCS. Entsprechende containerbasierte Anlagen entstehen auf dem Gelände des LUAT. Sie umfassen u.a. CO₂-Abtrennung und katalytische Co-Elektrolyse und stellen alle notwendigen Energie- und Stoffströme zur Verfügung.

Elektrolytische Herstellung von Synthesegas
Das Fraunhofer UMSICHT erarbeitet im Zuge des Projektes u.a. Grundlagen, um in einem Power-to-X-Reaktor die elektrolytische Herstellung von Synthesegas im Labormaßstab zu demonstrieren. »Dazu skalieren wir neuartige Gasdiffusionselektroden und setzen sie für die Aufgabe in angepassten Reaktoren ein«, erklärt Prof. Dr. Ulf-Peter Apfel, Leiter der Abteilung Elektrosynthese. »Weitere Komponenten der Elektrolysezellen werden so aufeinander abgestimmt, dass Verlustleistungen und Gasleckagen minimiert sowie die Zusammensetzung des Synthesegases möglichst kontrolliert variiert werden können.« Neben der Erstellung der erforderlichen Komponenten führt das Institut auch die Entwicklung, Errichtung und Inbetriebnahme eines skalierten Elektrolysesystems (inkl. der Teststandperipherie) durch und integriert alles in die Containerumgebung der Plattform.

Charakterisierung von Katalysatoren
Darüber hinaus testen die Wissenschaftlerinnen und Wissenschaftler des Fraunhofer UMSICHT Katalysator-Systeme, die neu von Evonik entwickelt worden sind und bei der Synthese von Alkoholen zum Einsatz kommen. »Wir schauen uns Umsatz, Menge und Konzentration sowohl der auftretenden Produkte als auch der Nebenprodukte an und haben dabei vor allem die Lebensdauer des Katalysators im Blick«, so Prof. Apfel. »Auf Basis unserer Testergebnisse nimmt Evonik dann weitere Optimierungen der Katalysatoren sowie deren Scale-up in Angriff.« Das beste System wird dann für den Pilotreaktor ausgewählt.

Die Bedeutung des Projektes hob Prof. Dr. Andreas Pinkwart bei der Übergabe des Förderbescheids hervor. »Die aktuellen Ereignisse zeigen einmal mehr, wie wichtig eine sichere und unabhängige Energieversorgung ist«, betonte der NRW-Minister für Wirtschaft, Innovation, Digitalisierung und Energie. »Eine zukunfts- und wettbewerbsfähige Industrie benötigt große Energiemengen und klimaneutral erzeugte Rohstoffe für ihre Produktionsprozesse. Power-to-X kann nicht nur dazu beitragen, dass wir unsere ehrgeizigen Klimaschutzziele erreichen, sondern auch zu einer unabhängigen Versorgung mit synthetischen Kraftstoffen und Chemikalien für unsere Industrie und unser Energiesystem der Zukunft.«

Medizinische Masken sind in der Pandemie zum Alltag geworden. Mit ihrem erhöhten Virenschutz gehen allerdings auch Verständigungsprobleme einher. Forschende des Fraunhofer UMSICHT haben für dieses Problem einen Kommunikationsadapter entwickelt, der die Stimme verstärkt und so das Gespräch erleichtert. Nun ist die Erfindung unter dem Namen maskAMP® geschützt und ein Patent erteilt.

Comedians, Sänger*innen und Politiker*innen – sobald Menschen auf einer Bühne sprechen, greifen sie fast schon selbstverständlich zum Mikrofon. In unserem Alltag dagegen verstehen wir uns normalerweise ohne Hilfsmittel. Mit Pandemie und Gesichtsmasken finden wir Verständigungsprobleme allerdings auch in alltäglichen Situationen wieder. Nicht ohne Grund erklingt am Empfang in der Arztpraxis oder an der Supermarktkasse immer öfter ein »Wie bitte?«. Das Fraunhofer IBP hat herausgefunden, dass die Masken 5 bis 15 Dezibel der Lautstärke schlucken. Somit fühlt sich die Entfernung zum Gegenüber mit Masken doppelt so groß an, wie sie tatsächlich ist.^[1]

»Im Alltag gleichen Menschen diese maskenbedingten Verständigungsprobleme mit einer lauteren Stimmgebung aus«, erklärt Melih-Ahmet Dimetokali, Mitarbeiter in der IT-Infrastruktur des Fraunhofer UMSICHT. »Das belastet allerdings die Stimmlippen und auch eine physiologische Stimmgebung funktioniert dann zum Teil nicht mehr.« Verstärkt wird das Problem gleichzeitig durch Mindestabstände und schalldämpfende Glasscheiben. Die Resonanz ist so noch stärker eingeschränkt und die Artikulation gehemmt. Wie das Fraunhofer IBP herausgefunden hat, machen sich dadurch auf längere Zeit Erschöpfungssymptome wie Heiserkeit, Halsschmerzen, aber auch Kopfschmerzen und Abgeschlagenheit bemerkbar.

Mit Kommunikationsadaptern wieder mehr verstehen können
Das UMSICHT-Forscherteam – bestehend aus Melih-Ahmet Dimetokali, Michael Joemann und Rasit Özgüc – hat als Lösung einen abnehmbaren Adapter entwickelt, der die Stimme verstärkt und so Gesprächssituationen erleichtert. »Anders als bei Konkurrenzprodukten mindert der leichte Adapter nicht den angenehmen Tragekomfort der Maske«, betont Rasit Özgüc aus der Abteilung Elektrochemische Energiespeicher. »Uns war bei der Entwicklung sehr wichtig, dass der Verstärker alltagstauglich ist. Denn auch wenn die allgemeine Maskenpflicht derzeit weggefallen ist, gibt es Personenkreise, die Gesichtsmasken auch vor und nach der Pandemie regelmäßig tragen müssen. In medizinischen und pflegerischen Einrichtungen (Arztpraxen, Krankenhäuser, Pflegeheime etc.) beispielsweise bleibt die Maskenpflicht bestehen, um ältere und vorerkrankte Menschen besonders zu schützen. Allein in Deutschland arbeiten an die 3,3 Mio. Menschen im öffentlichen Gesundheitswesen.«

Ein weiterer Vorteil des Verstärkers ist seine Wiederverwendbarkeit. Da er flexibel positionierbar und abnehmbar ist, kann er bei einem Wechsel der Gesichtsmaske auf ein neues Modell übertragen werden. Nutzende können den Adapter so einfach reinigen oder wieder aufladen. »Das macht ihn im Vergleich bereits erhältlicher Produkten auf dem Markt umwelt- und ressourcenschonend. Dort ist die Elektronik nämlich meistens fest in der Maske integriert«, erklärt Özgüc, »Trotzdem können wir mit geringen Materialkosten und ohne Mindestproduktionsmenge der steigenden Nachfrage gerecht werden.«

Erstes Patent für einen Kommunikationsadapter
Für maskAMP® haben die UMSICHT-Forschenden nun einen Patentschutz für Deutschland erlangt, welcher jetzt in die weltweite Anmeldung überführt wird.  Das Produkt umfasst zum einen den wiederverwendbaren Kommunikationsadapter für Gesichtsmasken und zum anderen das System aus Kommunikationsadapter und Gesichtsmaske. Auch das Verfahren zur Bereitstellung eines solchen Systems fällt unter den Namen. Damit ist maskAMP® der erste patentierte Kommunikationsadapter.

Entwicklung vom Prototyp zur Marktreife
»Bis es den Kommunikationsadapter zu kaufen gibt, wird es allerdings noch etwas dauern«, ergänzt Michael Joemann, einer der Miterfinder. »Unser System muss zur Marktreife entwickelt werden. Dafür suchen wir lizenznehmende Vertragspartner mit den entsprechenden technologischen Möglichkeiten und Vertriebskanälen. Interessierte wenden sich bitte unter dem Stichwort maskAMP® an Rasit Özgüc.

The DiloGroup informs at Techtextil in Frankfurt (June 21 – 24, 2022) about new developments aimed at improving production technologies with a focus on needlefelts.

It becomes more evident that the textile industry comes into the focus of regulatory authorities who push respecting sustainability principles and who initiate a new body of laws. Hence all industrial sectors are requested to achieve savings in material and energy. The textile machine building, of course, plays an important role by seizing this initiative and offering solutions for fibre pulp recycling and reduction of energy, water and ancillaries. DiloGroup has made big efforts to meet these challenges together with a circle of partner companies. In this regard focal points of the development work are:

1. Intense Needling
   Needling per se is a mechanical production method with a high energy efficiency. For this reason, the development efforts of DiloGroup aim at producing nonwovens by “intense needling” instead of water entangling, even for light nonwovens made of fine fibres for the medical and hygiene sector with an area weight of 30 – 100 g/m². This would result in a reduction of the environmentally relevant production costs; per annum to about 1/3 to 1/5 of current.
   Despite the prospective advantages of the mechanical intense needling method over the hydrodynamical, water entanglement is at the moment the most important production method for low area weights and highest production capacity and is also offered by the DiloGroup as general contractor in cooperation with partner companies.
2. “Fibre Pulp Recycling”
   Fibrous material in nonwovens and particularly used clothes can be successfully recycled, if staple length can be conserved in the tearing process. In the classical tearing process, staple lengths are dramatically reduced and therefore these fibres can only be used as base material for inferior uses in thermal or acoustic insulation or in protective textiles, transportation or protective covers etc.
   When recycling textile waste in the context of the collection of used clothes, the so called “filament-saving” tearing using special tearing machines and methods must be used to produce fibres with longer staple lengths which can be fed to a nonwoven installation. Hence product characteristics can be better specified and controlled.
3. Additive nonwoven production
   The additive production method of the “3D-Lofter” is especially suited for automotive parts with differently distributed masses; but there may also be potential for increasing uses in the sector of apparel and shoe production.
4. “IsoFeed”-card feeding
   In the field of card feeding, the “IsoFeed” method offers great potential for a more homogeneous card feeding at the same time reducing the variation in cross-machine fibre mass distribution and thus the fibre consumption while conserving the end product quality.

Gebr. Otto is exhibiting at this year’s Techtextil from 21 to 24 June in Frankfurt. The Dietenheim-based textile company manufactures a selected range of functional high-tech yarns made, for example, of conductive, high-strength and flame-retardant fibres. Gebr. Otto’s aim at the trade fair is to make personal contacts and to expand regional technology chains. The textile solution provider is to be found, as in past years, at the BW-I joint stand in Hall 12.1 at Booth No. C80.

Growing demand for technical yarns
“In the industry Gebr. Otto is mostly known for its cotton yarns and twines,” says Robin Hefter, who is in charge of technical textiles at Gebr. Otto. Cotton is the fibre that is mainly spun in the company’s spinning mill. It has been Gebr. Otto’s main line of business for over 100 years. The technical yarns that have been in the company’s product range for a good five years are, by contrast, still relative newcomers. They account for around 10 per cent of the company’s output, their share of which is on the increase. “Technical textiles have proved to be a growth sector in recent years,” Hefter explains, “and due to current political events demand for them has increased even further.”

Portfolio with a protective character
That is a reference to personal protective equipment – clothing and gloves. Gebr. Otto’s highperformance functional yarns, many of which are based on high-tech fibres, are specially designed for use in this area. In addition to flame-retardant yarns made of meta-aramid Gebr. Otto processes antistatic or conductive fibres.

As a rule many chemical fibres are easily electrically chargeable without being able to discharge by themselves due to their low moisture absorption. That is why undesired discharges occur,
maybe even the next time you shake hands. In some situations, they can be life-threatening. “Imagine the team at a pit stop in a Formula 1 race,” Robin Hefter says. “refuelling a racing car
under pressure of time. There must not be a single spark, no matter how small.” That is why Gebr. Otto adds antistatic fibres to its technical yarns. They prevent electrostatic charging and
offer safety not only to pit stop teams but also to filling station attendants. If electric conductivity is required, conductive fibres are added. And high-strength fibres are used if high or ultra-high tensile strength is required.

Colour fastness rather than safety is required when it comes to spun-dyed yarns. The fibres take up the pigments more homogeneously than if they are dyed as yarn. They are much more colourfast and fade markedly less in sunlight because the pigment particles are better enclosed in the fibre.

Leading knit solutions provider SHIMA SEIKI MFG., LTD. of Wakayama, Japan, together with its U.S. subsidiary SHIMA SEIKI U.S.A. INC., will participate in the Techtextil North America exhibition in Atlanta, Georgia, U.S.A. this month. Under the theme “techKNITians—Technical Engineered Knit Applications,” the company will display its latest computerized flat knitting machines and computer graphic design system technology, aimed at promoting knitted applications in the field of technical textiles.

Pioneered by SHIMA SEIKI, WHOLEGARMENT® knitting technology is capable of producing knitted items in their entirety without the need for sewing, and allows complex 3D forms to be knit such as car seat covers and interior furnishings. Selective compression allows control over placement and amount of pressure for various compression wear in sports and medical applications. The seam-free nature of WHOLEGARMENT® also ensures continuity of yarn, allowing functional yarns such as conductive yarns to wrap around the entire body without interruption, for applications in smart garments and wearable technology. Demonstrating the latest in WHOLEGARMENT® knitting technology at Techtextil will be the flagship MACH2XS machine that features the company’s original SlideNeedle™ on 4 needle beds and patented springloaded full-time sinker system. Capable of WHOLEGARMENT® knitting in all-needles, MACH2XS offers great flexibility for knitting high-quality WHOLEGARMENT® products with a seemingly endless variety of knit patterns at very high speed and efficiency, all while minimizing dependence upon labor-intensive sewing and linking. At Techtextil North America MACH2XS will be shown knitting a seam-free balaclava in one entire piece using fire-resistant yarn.

Also shown will be the SWG091N2 compact WHOLEGARMENT® knitting machine, also featuring SlideNeedle™ technology. Capable of producing small knitted items from safety gloves and compression socks to more sophisticated industrial applications such as tubular shields and harnesses, SWG091N2 offers unique solutions for the automotive, aerospace, sports, medical, safety, outdoor and other markets by knitting items in 3D without seams. SWG091N2 will be knitting fire-resistant gloves at Techtextil North America. SHIMA SEIKI’s SDS®-ONE APEX4 3D design system will also be available for demonstrations in design and simulation of various technical textiles. Of particular interest is its ultra-realistic simulation capability that realizes virtual sampling. When numerous variations must be evaluated before arriving at a final design, virtual product samples can be used to streamline the decision-making process by minimizing the enormous amount of time and cost normally associated with producing actual physical samples for each variation. The sustainability factor is also undeniable considering the amount of material normally gone to waste in the sampling stage.

The Techtextil and Heimtextil Summer Special exhibitions, taking place together in Frankfurt from June 21-24, represent an opportunity for Monforts to showcase its finishing and coating technologies for two of its major markets – especially at a time when energy prices continue to soar for textile manufacturers in Europe.

Existing customers of Monforts include many manufacturers in the field of home textiles, as well as those making geotextiles, automotive fabrics and other functional materials – all of whom will be well represented in Frankfurt this June. Dedicated Montex lines have also been supplied to producers of airbags, flame retardant barrier fabrics and spacer fabrics, as well as high-temperature filter materials.

Energy prices are rising steeply everywhere and a particular emphasis for Monforts in Frankfurt will be on the energy and heat recovery that can be achieved with Montex stenters, through features such as better insulation of the treatment chambers or the MonforClean system, in which waste heat from the drying process is used to pre-heat the drying air resulting in a radical reduction in the conventional heat supply required compared to gas and thermal oil heating. The modular system for heat recovery can also be extended for exhaust air cleaning and odour elimination. Monforts can provide a range of further resource-saving and energy recovery options tailored to each individual line installation including modification of the heating source.

With the Qualitex 800 visualization software, all article-specific settings can be stored and the formulations for thousands of treatment processes called up again at any time. Individual operators can also personalise their dashboards with the most important machine functions and process parameters.

The Qualitex 800 system is available for the automatic and continuous operation of the company’s Montex stenters, as well as its Thermex continuous dyeing ranges, Monfortex shrinking systems and Montex®Coat coating units.

Monforts Montex®Coat coating units serve an equally diverse number of markets, including tents, tarpaulins and awnings, black-out roller blinds and sail cloth, automotive interior fabrics and medical disposables. Full PVC coatings, pigment dyeing or minimal application surface and low penetration treatments and solvent coatings (in explosion-proof conditions) with knife coating, roller coating or screen printing can all be accommodated with this system.

All of these very different materials require coating and finishing for maximum efficiency, using Monforts technologies which provide the ultimate in flexibility and the ability to switch quickly from one fabric run to the next, without compromising on the economical use of energy or raw materials.

The Monforts EcoApplicator offers further potential for sustainably achieving perfect finishes via a precise direct application system, as an alternative to conventional padding – where fabrics are immersed in a bath of the required finishing chemicals. It can significantly further reduce the energy and water required and finishes can be applied on just one side of the fabric, or both, and even separately on each side, to be sealed in place via different heating zones in the stenter.

Um erfolgreich zu segeln, muss alles zusammenkommen: Kraft, Ausdauer und Erfahrung des Teams, modernste Technik und bestes Material rund um das Boot. Besonders, wenn es um die Highspeed-Variante des Segelns geht, das Foilen. Durch gewölbte Tragflügel am Rumpf, die Foils, hebt sich das Boot beim Segeln aus dem Wasser, reduziert so den Wasserwiderstand und erreicht eine Spitzengeschwindigkeit von 35 Knoten bzw. 65 Kilometern pro Stunde. Die hohen Geschwindigkeiten und die raue Umgebung – Sonne, Wind und Salzwasser – stellen enorme Anforderungen an das verwendete Material. SEILFLECHTER produziert die notwendigen anspruchsvollen Seile und lässt sie von einem erfolgreichen Segler testen, Lukas Hesse.

Derzeit ist Lukas Hesse, 22 Jahre, Deutscher Meister 2020 auf der 49er Jolle, mit dem Schweizer Jann Schüpbach und der Hawaiianerin CJ Perez als „Clean Sailors Youth Racing Team“ beim 69F Youth Foiling Gold Cup am Start. Eins der fünf Rennen, die Bacardi Cup Invitational Regatta in Miami, hat das Team Mitte März auf ihrer Persico 69F gewonnen.

Das erfolgreiche Racing-Team arbeitet mit der gemeinnützigen Organisation Clean Sailors zusammen, die sich den besseren Schutz der Umwelt auf die Fahnen geschrieben hat und einen neuen Standard für sauberes Segeln innerhalb der globalen Segelgemeinschaft setzen will. Der Fokus liegt dabei auf langlebigen und performanten Materialien und dem Re- bzw. Upcycling von gebrauchtem Material. SEILFLECHTER unterstützt Clean Sailors bei diesen Vorhaben.

Lukas Hesse setzt voll auf die Top-Seile von SEILFLECHTER. Sie sind belastbar und robust und tragen so dazu bei, das Segeln umweltfreundlicher zu machen. Die Erfahrungsberichte von Lukas Hesse helfen SEILFLECHTER, die Seile kontinuierlich zu optimieren.

Hexcel will present a wide range of high-performance composite innovations for the Automotive, Marine, Wind Energy and Recreation markets during JEC World 2022 in Paris on May 3 – 5.

G-Vent Technology for Marine Structures
Hexcel has developed a new technology for out-of-autoclave (OoA) processing that delivers a game-changing reduction in process time and cost for marine manufacturers without compromising mechanical performance. Hexcel has leveraged its experience in aerospace and wind energy to develop its new G-Vent technology for OoA processing of highly loaded, thick section marine structures such as masts, foils, and wind-assisted ship propulsion (WASP) components. A full range of Hexcel marine prepregs are now available with integrated G-Vent technology, reducing the requirement for debulking steps and ensuring extremely low porosity (<1%) regardless of the laminate thickness. Leading marine non-destructive testing specialists Q.I. Composites recently confirmed that the thick section G-Vent panels they had evaluated had void contents and laminate quality in line with state-of-the-art autoclaved prepreg components. Visitors to the Hexcel stand will see a unique 400mm carbon cube cured in a single stage using 695 layers of HexPly M79 carbon fiber UD600 prepreg with G-Vent technology.

New HexPly® Nature Range Sustainable Prepregs
HexPly® Nature Range prepregs feature proven resins such as HexPly M49, M78 and M79 with bio-derived epoxy resin content. Created for use in all industrial markets, HexPly Nature Range materials can be seamlessly integrated into existing production processes, maintaining consistent mechanical performance and processing properties. A dedicated sustainability corner of the Hexcel stand will detail Nature Range products optimized for automotive, marine, wind energy and winter sport applications. The display will include an alpine ski produced by leading manufacturer Tecnica Group Ski Excellence Center which produces skis for Blizzard and for Nordica using HexPly Nature M78.1 UD flax prepreg material. In addition to the reduced environmental impact of the sustainably grown reinforcement, the flax fiber laminates also improve impact resistance and vibration damping in the ski.

HexPly® XF Surface Technology for Improved Part Surface Finish Quality
HexPly XF is a lightweight, semi-preg material that replaces traditional in-mold gel coat. It eliminates time-consuming refinishing work typically required to obtain a paint-ready surface and produces lighter, more consistent parts with shorter cycle times and a cleaner working environment. Visitors to the stand will see a composite panel illustrating a high-quality painted surface enabled with XF technology in a diverse range of industrial applications such as super yacht roof parts, Class A surface automotive panels, and both prepreg and infused wind turbine blades.

HexPly® M49 Prepreg for Automotive Visual Carbon Parts
HexPly M49 is easy to process and is especially suitable for visual carbon fiber-look applications such as the Brabus hood scoop on display on the Hexcel stand at JEC.

HexPly® Prepregs and HiMax® Reinforcements for Performance Marine Structures
Using a scale model of a Gunboat 68 performance sailing catamaran, Hexcel will illustrate how its HexPly and HiMax materials provide manufacturers with a complete set of lightweight composite solutions for high-performance marine structures. HexPly prepreg was selected for critical structural parts of the Gunboat 68 and provides very high mechanical performance including high dry and wet Tg.

Heavyweight HiMax reinforcements offer high deposition rates and remain easy to handle after cutting, making them highly suitable for industrial applications. In combination with a lightweight PrimeTex® woven fabric, the package of carbon fiber HiMax materials developed for the Gunboat 68 enabled consistent resin flow during infusion with reduced surface print-through.

Hexcel Fibers and Reinforcements for Lightweight Sporting Equipment
Sporting equipment manufacturers rely on Hexcel composite materials to deliver the ultimate performance at the lowest possible weight. Hexcel will exhibit a number of the latest high-performance sporting equipment applications such as a Bauer hockey stick featuring PrimeTex 98 gsm AS4C 3K fabric and a Corima tri-spoke cycling wheel made with lightweight Hexcel carbon fiber UD tape. Hexcel will also demonstrate how its HexTow® carbon fibers are used in key leisure and marine applications by displaying an AEROrazr solid carbon rigging component manufactured by spar and rigging manufacturer Future Fibres for the 36th America’s Cup.

At the forthcoming Texprocess, Techtextil and Heimtextil shows taking place in Frankfurt from June 21-24 – members of the Swedish Textile Machinery Association TMAS will be showcasing a range of solutions aligning with the growing trend for more localised and automated textile manufacturing.

Digitalisation and the push for more sustainable, shorter and less expensive supply chains are currently making manufacturing in high-cost countries within Europe more attractive and there have been many other contributing factors to this over the past two years.

The Covid-19 pandemic exposed the vulnerability of many countries to shortages of essential items like PPE while at the same time making the full exploitation of new digital options essential during national lock-downs and long periods of restricted travel. The escalating cost of global transportation, as well as the growth of online retailing and the associated benefits of on-demand digital manufacturing, are further reinforcing the many benefits of short-run and near-shore new operations.

Secure supply
At Texprocess, for example, Eton Systems will be unveiling its latest Ingenious software solution which further enhances the company’s Opta Unit Production System (UPS) introduced in 2021.

“Our automated technology has already had a great impact on the productivity of thousands of garment production lines,” says Eton’s Managing Director Jerker Krabbe. “Our systems help producers across the world to reduce repetitive manual tasks and increase efficiency, which evens out some of the differences between production in high and low-cost countries, making reshoring a feasible option. Creating a diversified production portfolio with a mix of production facilities, some closer to home, makes for a more secure product supply.”

Flexibility
Imogo meanwhile recently installed the first industrial scale dyeing system in Sweden for many years. The Dye-Max spray dyeing line has the potential to slash the use of fresh water, wastewater, energy and chemicals by as much as 90% compared to conventional jet dyeing systems. It is capable of carrying out the application of a wide range of fabric pre-treatments and finishing processes, providing users with unbeatable flexibility in production.

“Here in Scandinavia, we are currently seeing an explosion of companies developing sustainable new cellulosic fibres – many from waste clothing – but a problem is that all of the environmental benefits they deliver can potentially be lost in the further processing, and especially in conventional dyeing,” observes the company’s Founding Partner Per Stenflo. “The Dye-Max system positively addresses this, but interest in it has not just been confined to Europe. We are currently seeing a lot of activity in Turkey – largely as a near-shore partner to European brands – but also in Bangladesh.”

Robotics at Heimtextil
ACG Kinna Automatic specialises in automation solutions for filled products such as quilts, pillows and mattresses and its live demonstrations of robotics in action have proved a magnet for visitors to Heimtextil. This year’s show will be no exception.

“The use of robotics is now standard across many industries dealing in solid goods, but the handling of soft materials such as textiles is a little more complex,” says Managing Director Christian Moore. “Nevertheless, it’s something we have successfully mastered, and our robotic systems are proving highly beneficial to their users. There is no ‘one-size-fits-all’ solution when it comes to automation and our approach is always to carefully examine where it will make the difference in each bespoke system. A focus is on identifying and eliminating bottlenecks which will increase product flows.”

During the Covid-19 pandemic, ACG Kinna drew on all of its automation know-how and extensive network of contacts to build a new nonwovens fabric converting and single-use garment making-up plant in a matter of weeks, in order to supply the Swedish authorities with urgently-needed medical gowns.

Instant colour
Localised textile production is also booming in the USA, where Coloreel has recently secured multiple orders for its instant thread colouration technology via its US partner Hirsch.

“Coloreel technology enables the high-quality and instant colouring of a textile thread while it is actually being used in production and can be paired with any existing embroidery machine without modification, while also making it possible to produce gradients in an embroidery for the first time,” explains VP of Sales Sven Öquist.

“Advanced rapid colour formulation software and high-speed drive technology allow a single needle to carry out what it previously required many multiples of them to do – and with much more consistent stitch quality. By instantly colouring a recycled white base thread during production, our system enables complete freedom to create unique embroideries without any limitations. Colour changes along the thread can either be made rapidly from one solid colour to another, or gradually, to make smooth transitions or any colouring effect desired. This provides big benefits when it comes to sustainability and design creativity.”

Milestone
Svegea will be promoting its latest EC 300 collarette cutting machine at Texprocess 2022. This machine is used by garment manufacturers around the world for the production of tubular apparel components such as waistbands, cuff and neck tapes and other seam reinforcements. With its E-Drive 2 system and fully automatic FA500 roll slitter, the EC 300 has an output of around 20,000 metres per hour.

“Advances in automation are only making the specialised, bespoke machines we engineer even more efficient and we are expecting a very busy year,” says Managing Director Håkan Steene. “The garment components our collarette cutters produce make it logical for them to be integrated into the operations of making-up operations, wherever they are.”

Sensors
The advanced yarn tension monitoring technologies of Eltex of Sweden meanwhile play an essential role in rectifying defects in  weaving, tufting and composite reinforcement operations.

“A correct tension of the warp and weft threads ensures proper machine operation,” explains Eltex Global Marketing and Sales Manager Anoop K. Sharma “The constant tension monitoring and automatic control of the tension of the thread help to overcome unnecessary problems.

“We continue to make advances in both the hardware and software of our tension monitoring systems, such as the EyE™ for the warping process. With the EyE™, the yarn tension values from all yarns are continuously updated and displayed on screen. In addition, tension values outside the warning level are indicated both on the sensor’s LEDs and on the screen for complete quality control. No fabric can be woven without the appropriate and correct tension.”

Monforts will highlight its advanced finishing and coating technologies for the production of technical textiles at Techtextil North America, which takes place at the Georgia World Congress Center in Atlanta from May 17-19.

The company and its US representative PSP Marketing, of Charlotte, North Carolina, will be part of the centrepiece VDMA German Pavilion at the show.

Energy prices
With energy prices continuing to go through the roof, an emphasis at Techtextil North America will be on the energy and heat recovery that can be achieved with Montex stenters, through features such as the MonforClean system, in which waste heat from the drying process is used to pre-heat the drying air. This results in a radical reduction in the conventional heat supply required. A range of further resource-saving and energy recovery options can be specified per individual line installation.

Advanced machine operation
With the highly intuitive Qualitex 800 visualization software, all article-specific settings can be stored and the formulations for thousands of treatment processes called up again at any time. Individual operators can also personalise their dashboards with the most important machine functions and process parameters.

The Qualitex 800 system is available for the automatic and continuous operation of the company’s Montex stenters, as well as its Thermex continuous dyeing ranges, Monfortex shrinking systems and Montex®Coat coating units.

Versatility is the key
Monforts Montex®Coat coating units serve an equally diverse number of markets, including tents, tarpaulins and awnings, black-out roller blinds and sail cloth, automotive interior fabrics and medical disposables. Full PVC coatings, pigment dyeing or minimal application surface and low penetration treatments and solvent coatings (in explosion-proof conditions) with knife coating, roller coating or screen printing can all be accommodated with this system.
