High-performance yarns now offer almost unlimited possibilities for replacing traditional raw materials in a vast range of technical applications. Often tailor-made, these filament yarns go way beyond the conventional idea of ‘textiles’ – finding new uses in sectors such as automotive, aviation, maritime, medical and construction, among many others.

Technical textiles are everywhere in our daily lives today, even if we may not always realize it. Some are in more obviously textile products, from sewing threads to artificial turf. But then, take cars as an example: modern vehicles are stuffed with parts made from sophisticated yarns. It’s common for producers of automotive parts now to send template material and requirement lists to Swiss Textile Machinery members, trusting their expertise and experience. Members operate development and testing centers with latest machine installations, where their experts devise customized solutions, as well as calling on the pure innovative spirit which is part of their DNA.

At the extremes
Technology drives applications beyond our current imagining in the case of Heberlein air splicers. Developed for a wide range of uses with high-strength technical fibers, they have no problems splicing aramid fibers up to 16’100 dtex, carbon up to 30’000 dtex, Dyneema up to 5’500 dtex, and glass up to 4’800 tex. Using compressed air, the splicers produce a tear-resistant, homogeneous splice of material without interfering knots.

Retech has the technology to achieve specifications for filament yarns, drawing and stretching fibers to perfection. Top heated godet rolls – many customized – are developed for high-performance fibers. Temperatures up to 400 °C can be achieved. Combining the right settings and wide speed ranges for each specific process results in unique end-products.

Fabric producers of high-end applications must avoid any quality risk. Yarn producers are well aware of this responsibility, so they use precision package winders for technical yarns, developed by Rieter’s subsidiary SSM. Taking yarns from ring twisting bobbins, its specialist finish winders can produce coarse-count technical yarns up to 50’000 dtex, offering a new level of flexibility and winding quality.

Lifestyle essentials
At first glance, motorists might fail to notice many of the technical yarns ‘hidden’ inside their cars. These products have functions such as providing stability with hardly any weight, or absorbing tensile forces at defined elongation. This kind of controlled elongation behaviour, for example, arises from the choice of textile material and the special construction of the yarns used.

Such specifications make twisting and cabling machines essential for the automotive industry. Saurer offers machines for the production of technical yarns made from a variety of feed materials in a very wide yarn count range. They are needed for vehicle products such as tire carcasses, toothed engine belts, seat belts, airbags and lorry tarpaulins.

Technical yarns also play a surprising role in our mobile devices. Tapping, scrolling and swiping are second nature for billions, with our phones and a plethora of other lifestyle essentials. Yet, how many people would know that the touch-sensitivity we take for granted on these screens is largely made possible by twisted glass fibers. Bräcker, part of Rieter’s components business, offers a selection of vertical sinter metal rings and nylon travelers for glass fiber twisting, so that mills can achieve high levels of productivity and quality.

Future unlimited
Automotive and communication technology are already important industries for Swiss Textile Machinery members, along with well-known technical textiles markets in sectors such as medical, transport and construction. Smart-wear is already noted as a field with significant potential. Naturally, members are constantly investigating other possibilities. Swiss textile machinery is already applied in energy (batteries), and plastics.

The Swiss Textile Machinery Pavilion will be at the Techtextil exhibition in Frankfurt, Germany, taking place from 21 to 24 June 2022.

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.

Gemeinsam mit insgesamt 46 Industriepartnern konnten mehrere, verschiedene Konzepte für Kunststoff-basierte Multimaterial-Batteriegehäuse erarbeitet werden, mit denen deutliche Einsparpotentiale bei Gewicht und Kosten möglich sind. Im Projektverlauf kristallisierten sich zwei wichtige Kernthemen heraus, die in Folgeprojekten gesondert behandelt werden sollen: Bodenaufprallschutz und Feuerbeständigkeit. Diese zwei Folgeprojekte starten am 26. Januar 2022. Ein Projekt zur Entwicklung und Realisierung von Prototypen für Mitte nächsten Jahres 2022 ist in Planung.

Batteriegehäuse gehören zu den Schlüsselkomponenten in E-Fahrzeugen und werden derzeit in der Regel aus Aluminium hergestellt. Genau diese Komponente analysierte das AZL in dem jetzt durchgeführten Projekt mit einem großen Konsortium aus Automobilherstellern, Automobilzulieferern, Rohstoffherstellern und Maschinenherstellern. „Der enorme Zuspruch aus der Industrie unterstreicht die Relevanz des Themas“, freut sich der Projektleiter Warden Schijve, der zudem sehr zufrieden mit dem Verlauf und den Ergebnissen ist. Schließlich lassen sich bis zu 36 % des Gewichts und bis zu 20 % der Kosten einsparen, wenn anstelle herkömmlicher Lösungen Multi-Material-Verbunde auf Basis von Kunststoffen zum Einsatz kommen.

Um zu den Ergebnissen zu gelangen, hat das AZL unter Mitwirkung seiner Partnerunternehmen, zu denen unter anderem Audi, Asahi Kasei, Covestro, DSM, EconCore, Faurecia, Formosa, Hengrui, Hutchinson, IPTE, Johns Manville, Magna, Marelli und Teijin, gehörten, zunächst fünf Subkomponenten eines Batteriegehäuses definiert: die Gehäusewanne, die Bodenschutzplatte, den Crash-Rahmen, die Querbalken und den Gehäusedeckel. Außerdem analysierten die Partner insgesamt 44 marktrelevante, existierende Serienkomponenten und Konzepte genauer und erstellten eine umfangreiche Übersicht über die verschiedenen Standards sowie Anforderungen auf nationaler, internationaler und OEM-Ebene. Prämisse dabei war, gleiche oder gar bessere mechanische Kennwerte zu erreichen als bei herkömmlichen Lösungen. So sollten beispielsweise mindestens gleiche Steifigkeiten, Sicherheiten bei seitlichem Aufprall, EMI-Abschirmung sowie Flammschutz vorhanden sein. Um nun die alternativen Lösungen zu ermitteln, entwickelte das AZL 20 Designkonzepte mit unterschiedlichen Materialkombinationen. Zur Analyse und Auslegung der verschiedenen Konzepte wurden mehr als 500 FEM-Modelle erstellt und über 1.500 CAE-Simulationen durchgeführt.

Während sich Folgeprojekt 1 mit einer anwendungsbezogenen Testmethode und der Untersuchung der Sicherheit verschiedener Materialkombinationen für den Bodenaufprallschutz beschäftigt, steht in Folgeprojekt 2 die Flammresistenz verschiedener Materialien und Materialkombinationen im Vordergrund. Ziel ist es Prüfverfahren zu entwickeln, die es erlauben, die Aufprall-/Feuerbeständigkeit auf Materialebene unter Berücksichtigung der spezifischen Anforderungen an ein Batteriegehäuse im Vergleich zu Standardmaterialien zu untersuchen.

The acoustic performance of components for the vehicle interior such as inner dashes or carpets depends on the noise-reducing quality as well as the geometrical adaptability and fill power of their material. With Flexi-Loft, Autoneum offers a new felt-based technology that thanks to a unique blend of recycled cotton and functional fibers reduces product weight and allows for accurate adaptation even to complex shapes. The textile material therefore provides a versatile and more sustainable alternative to foam.

In order to achieve high acoustic performance at minimum weight and maximum sustainability, Autoneum is continuously advancing its textile product portfolio. When it comes to components for the vehicle interior, for example, standard thermoplastic felts excel through their acoustic absorption, robustness and environmental friendliness. However, since felt-based materials are generally less voluminous and moldable as foam components, they require more weight to thoroughly fill the areas of varying thickness between the surface of the component and the vehicle’s body-in-white. In contrast, Autoneum’s Flexi-Loft technology is significantly lighter, more flexible and more adaptable than standard felts. In addition, the fiber-based material is versatile and clearly outperforms current foam products in terms of sustainability.

Thanks to its blend of recycled cotton and polyester fibers, Flexi-Loft substantially reduces component weight while improving geometrical adaptability and acoustic performance, especially in areas of low thickness. Thanks to the specific properties of the fibers, Flexi-Loft enables a precise adaptation to a wide variety of vehicle bodies, thereby improving the noise-insulating qualities of the respective product. Even at low weight, Flexi-Loft covers a wide range of material thicknesses, thus proving to be an ideal decoupling material for interior components with complex shapes such as inner dashes and automotive carpets. As a lightweight, flexible and sustainable alternative to both standard felts and foam, Flexi-Loft distinguishes itself by its versatile application in combination with existing Autoneum technologies such as Hybrid-Acoustics and Prime-Light. Moreover, the material helps to reduce odor and dust inside the vehicle.

Flexi-Loft consists of at least 50% recycled cotton fibers, and cut-offs generated during the manufacturing process are reclaimed, processed and then reused in the production of new felt blanks.

Autoneum is already using Flexi-Loft worldwide as an insulator for various carpets, inner dashes and other acoustic components based on its Prime-Light technology. The application of the material as an effective decoupler in inner dashes made of Hybrid-Acoustics will be launched on the European market in 2023.

• Polynova to gain market share for the GRAFE Group in the Swiss region from November The GRAFE Group, Blankenhain, has found a new sales representative for Switzerland in Polynova Group AG, Risch-Rotkreuz (Switzerland).

The partnership will be officially launched at Fakuma 2021. "Our new Swiss agency specialises in the distribution and production of high-quality technical plastic granulates and has been active on the market for more than 20 years. The company has a large customer base and the necessary technical expertise to advance our goals in this important market. This includes raising our profile, educating people about our product range and ultimately gaining market share," says Stefanie Theuerkauf, Sales Manager for the D-A-CH region. Polynova employs five sales staff and three in logistics, all of whom have a technical background. The company's own warehouse in Rothenburg also ensures the availability of the plastics.

"GRAFE fits perfectly into our product portfolio," says Thomas Weigl, co-owner and responsible for business development at the Swiss distribution company, whose employees recently underwent intensive training in Blankenhain. "Our customers come from the sports goods, housing technology, automotive supplier and medical technology sectors - there are many synergies with GRAFE." Weigl himself has extensive experience in the masterbatch sector and has worked for two companies in the industry - Sukano and Americhem - as managing director. "Swiss companies want Swiss contact persons. We speak the languages German, Italian and French, are on site in the shortest possible time, offer direct contact and understand the needs of the customers and the requirements of the market," he explains. "Polynova is thus faster, closer and more direct." "The Swiss market is large and important for us," reports Theuerkauf and Weigl explains the background: "There are over 300 plastics processors, many are family-run and very technically oriented. The origins of the companies are often in the watch industry and in the production of the smallest precision parts such as gear wheels. In addition, coffee machine manufacturers, medical technology providers and automotive suppliers are important market players. A large number of well-known OEMs are located here."

Even though there are already masterbatch manufacturers in the Alpine country, says the sales expert, no one has the know-how to adjust compounds and masterbatches as perfectly and precisely as the company from Thuringia. In addition to a complete range of colours on practically all plastic substrates, flame retardants, UV additives, thermal stabilisers or lubricants are further examples of the extensive product portfolio. GRAFE is one of the specialists in the modification of thermoplastics and is an innovation driver in the production of colour masterbatches. "The technical possibilities in terms of a state-of-the-art technical centre and production machinery, as well as one of the largest research and development departments in the industry, are also not to be found elsewhere on the Swiss market. Our task now is to bring these to the attention of domestic customers," says Thomas Weigl, co-owner of Polynova AG together with founder Renato R. Huebscher.

Hexcel has collaborated with HP Composites S.p.A (HP Composites), a world leader in the production of carbon fiber components for automotive and motorsports, to develop carbon fiber Class A body panels. Hexcel HexPly® XF surfacing technology is being extensively used by the Italian component producer to manufacture external body panels and other components for supercars such as Alfa Romeo’s stunning new supersport sedans, the Giulia GTA, and GTAm.
