From the Sector

KARL MAYER GROUP will be presenting a WEFTTRONIC® II G at the ITMA with new features and upgrades for greater efficiency. This warp knitting machine with weft insertion produces lattice structures from high-strength polyester, which are firmly established in the construction industry in particular. With a working width of 213", it offers productivity and further advantages through design innovations. New features include weft thread tension monitoring, management and the new VARIO WEFT laying system. The component for the weft insertion aims at maximum flexibility. It allows the patterning of the weft yarn to be changed quickly and easily electronically, without mechanical intervention during yarn insertion and without limits on repeat lengths. In addition, there is less waste.

The KARL MAYER GROUP also supports its customers with well thought-out Care Solutions. The new support offers include retrofit packages for retrofitting control and drive technology for weft insertion and composite machines, and service packages that bundle various services. These include machine inspections and the replacement of all drive belts. The customer benefits from fixed prices that cover the costs of technician assignments, various discount options and transparent services.

A new solution for the vertical greening of cities is presented from the field of application for technical textiles. The core of the innovation is a grid textile produced on warp knitting machines with weft insertion by KARL MAYER Technische Textilien GmbH. The knitted lattice fabric is made of flax. It is used as a climbing aid for fast-growing plants, and after the greening phase, in autumn, it can be recycled together with these plants as biomass in pyrolysis plants to produce electricity and activated carbon. In summer, the planted sails lower the ambient temperature through evaporation effects. In addition, photosynthesis creates fresh air and binds CO2. Other important advantages are low soil requirements and flexible placement in public spaces. The greening system was developed by the company Micro Climate Cultivation, OMC°C, with the support of KARL MAYER Technische Textilien.

The KARL MAYER GROUP will also be exhibiting a sustainable composite solution made from natural fibres. The reinforcing textile of the innovative lightweight material is a multiaxial non-crimp fabric, which was also produced from the bio-based raw material flax on a COP MAX 4 from KARL MAYER Technische Textilien. The boatbuilding specialist GREENBOATS uses natural fibre composites to achieve sustainable products. The fact that it succeeds in this is shown, for example, by the Global Warming Potential (GWP): 0.48 kg of CO2 per kilogram of flax reinforcement compares with 2.9 kg of CO2 per kilogram of glass textile.

Viscose speciality fibre manufacturer Kelheim Fibres, nonwoven producer Sandler, and hygiene product manufacturer pelzGROUP have jointly developed a new panty liner that is plastic-free according to the European Single-Use Plastics Directive (SUPD). This innovative solution is a step towards reducing the amount of plastic in hygiene products – and thus also a contribution to tackling the problem of plastic pollution.

According to a UNEP study on marine litter and microplastics, eight million tons of plastic end up in the oceans every year. A significant portion of this pollution comes from single-use plastic products, including conventional period products such as pads or panty liners.

The partnership between the three companies was formed under the Open Innovation principle, which allowed for creative idea exchange and facilitated the development of an innovative product. According to Jessica Zeitler, R&D Specialist at Sandler, “Our collaboration with Kelheim Fibres and pelzGROUP is a great example of how companies can work together to create solutions that benefit both the environment and consumers. We are proud to be part of this project and the opportunities it offers.”

For hygiene product manufacturer pelzGROUP, it is important to combine sustainability and performance to achieve broad acceptance in the market. “Our panty liner meets the strict requirements of the European Single-Use Plastics Directive (SUPD) while also matching the performance of conventional synthetic products. At the same time, our new panty liner has a completely European supply chain. This means short distances and therefore low CO2 emissions, and – especially in times of global disruption – reliability for our customers,” emphasizes Dr. Henning Röttger, Head of Business Development at pelzGROUP.

"Our viscose speciality fibres are an environmentally friendly and high-performance alternative to synthetic materials," says Dominik Mayer, Project Manager Fibre & Application Development at Kelheim Fibres. "They are at the very beginning of the product value chain and yet have an enormous impact on the functionality of the end product. Open innovation allows us to bring all partners in the value chain to the table, to find the best solution together in a very short time and bring it to commercialisation - the collaboration with Sandler and pelzGROUP is an important milestone in our AHP journey."

The acquisition of the automotive business of Borgers, announced in January 2023, has been completed with effect from April 1, 2023, following receipt of all antitrust approvals. As a result, Autoneum now operates 67 production facilities worldwide and employs around 16 100 people in 24 countries. With the acquisition of the long-established German company, Autoneum is further expanding its global market leadership in sustainable acoustic and thermal management of vehicles. For the planned capital increase of around CHF 100 million for the long-term financing of the acquisition, the shareholders approved the creation of a capital band.

The purchase agreement signed on January 6, 2023, to acquire the assets of the insolvent Borgers companies by Autoneum could be completed. As a result, Autoneum will take over the assets of the Borgers companies in Germany and the shares in the subsidiaries in France, Poland, Sweden, Spain, the Czech Republic, the United Kingdom and the USA as well as in the company in Shanghai, China, with effect from April 1, 2023. As already communicated, the enterprise value paid amounts to EUR 117 million.

The product and customer range of Borgers Automotive, the specialist for textile acoustics protection, insulation and trim for vehicles, ideally complements Autoneum’s sustainable product portfolio. Particularly with the wheel arch liner and trunk lining product lines as well as the truck business, Autoneum’s global presence offers further potential for profitable growth also outside Europe. In addition, Borgers has more than 150 years of experience in recycling textile materials. In the 2022 financial year, the Borgers Group – excluding the mechanical engineering division which was already sold in the summer of 2022 – generated expected annual revenue of around EUR 700 million and employed around 4 500 employees worldwide. Autoneum has agreed new pricing and delivery terms with Borgers’ customers, which will ensure both sustainable profitability and the further development of technologies and processes.

From April 1, the former Borgers sites in Germany will be part of Autoneum Germany GmbH, which has been in existence for many years. The other subsidiaries worldwide will gradually be renamed Autoneum.

Ob in Gastronomie und Handel, auf der Baustelle oder in der Produktion, viele Millionen Berufstätige in Deutschland tragen täglich Arbeitskleidung. Dabei sie dient der funktionalen Unterstützung oder optischen Team- Zugehörigkeit, in manchen Branchen schützt sie Mitarbeitende vor Gefahren.

Dominique Frühauf, Produktmanagerin bei CWS Workwear, erklärt die Unterschiede zwischen Arbeitskleidung und Schutzkleidung.
Arbeitgeber setzen für ihre Angestellten auf Berufsbekleidung, da diese Sicherheit und einen gewissen Wiedererkennungswert des Unternehmens bietet. Firmenlogo und Namensschild sollten dabei nicht fehlen. So fördert die Kleidung den Zusammenhalt der Mitarbeitenden und sorgt für ein professionelles, repräsentatives Erscheinungsbild.

Aber gut ausgestattet in den Tag zu starten, bedeutet mehr als nur eine professionelle Optik. Je nachdem in welchem Bereich ein Mitarbeitender tätig ist, kann auch eine Schutzkleidung notwendig sein.

Funktionalität und Sicherheit
Zunächst muss Arbeitskleidung richtig passen und gut aussehen. Funktionalität und Komfort sorgen dabei für das ideale Gesamtpaket. Sollte keine Schutzkleidung benötigt werden, reicht eine Workwear. Je nach Tätigkeitsfeld der Mitarbeitenden gilt es dabei, die Anforderungen an Abnutzung und gegebenenfalls Besonderheiten wie Arbeiten im Knien, Bücken oder im Freien einzubeziehen. Auf dieser Basis sollten die Dicke und Widerstandsfähigkeit des Gewebes, und funktionale Details wie Verstärkungen oder Polster für den Kniebereich ausgewählt werden. Bewegungsfreiheit und Wohlfühlen steht bei den Anforderungen einer Arbeitskleidung ganz oben auf der Liste für Mitarbeitende.

Risiko oder nicht?
Wird eine Persönliche Schutzausrüstung, PSA, benötigt so muss diese Mitarbeitenden vom Arbeitgeber zur Verfügung gestellt werden. Durch eine Risikobewertung des Arbeitsplatzes wird das Risiko beziehungsweise die Wahrscheinlichkeit eines Gesundheitsschadens durch bestimmte Gefahrenstoffe oder Tätigkeiten bestimmt. In Deutschland legen oft die Berufsgenossenschaften für Branchen fest, welche Berufskleidung getragen werden muss. Die Unternehmen müssen für die Sicherheit der Mitarbeitenden während der Arbeitszeit sorgen.

Die Risikogruppen der Schutzkleidung
Es gibt drei verschiedene Risikokategorien von PSA. Je nachdem, ob und wie wahrscheinlich das Risiko einer Verletzung besteht, fällt die Gruppe aus. In Kategorie I fällt Schutzkleidung, die vor einer geringfügigen Gefährdung schützt, wie z.B. Wetterschutz. Kategorie II bedeutet Schutz gegen ein mittleres Risiko. Ein Beispiel dafür ist die Warnschutzkleidung. Bei Kategorie III handelt es sich um komplexe PSA, die vor lebensbedrohlichen Gefahren schützt. Dazu gehört u.a. Hitze- und Flammschutz. Zudem unterliegt jede Schutzkleidung mindestens einer Norm, innerhalb derer es auch noch Abstufungen hinsichtlich der Schutzanforderungen geben kann.

Passform und Komfort
Passt und sitzt eine Arbeitskleidung richtig, fühlen sich Mitarbeiter:innen automatisch wohler. Bei PSA spielt der Tragekomfort zusätzlich eine wichtige Rolle. Denn sind gute Bewegungsmöglichkeiten in der Schutzkleidung gegeben, können Mitarbeitende Gefahren schneller ausweichen. Bei der Zertifizierung der Normen einer PSA wird daher auch die Passform überprüft.

Was könnte also passieren, wenn eine gute Passform nicht gegeben ist? Bei Normen wie Hitze- und Flammschutz müssen beispielsweise Hose und Jacke stets überlappen, selbst dann, wenn die Arme gestreckt werden. So soll sichergestellt werden, dass der Körper auch bei Bewegungen gut geschützt ist. Bei Warnschutz sollte insbesondere die Bein- und Armlänge für den Mitarbeitenden stimmen. Denn ist die Hose zu lang und verschwinden die Reflexstreifen in der Schuhfalte, ist die Sichtbarkeit nicht mehr gegeben und eine erhöhte Gefahr für den Träger besteht.

Design und Verarbeitung
Unternehmen, die Arbeitskleidung und Schutzkleidung für ihr Team einsetzen, wünschen sich übergreifend eine ansprechende Optik und einen einheitlichen Look. Hersteller bieten daher Arbeits- und Schutzkleidung in gleichen Farben und ähnlichen Designs an, damit alle Mitarbeitenden miteinander optisch harmonisieren.

Bei Schutzkleidung gibt es einige Einschränkungen beim Design. Denn es gilt das Dachziegelprinzip: Schweißperlen, Flüssigmetalle – alles muss von oben nach unten an dem Textil abperlen können. Nichts darf in Nähten hängen bleiben. Daher hat Schutzkleidung meist weniger Nähte, auch weil sie häufig aus dickerem Gewebe besteht, das schwieriger zu verarbeiten ist. Auch bei den Taschen gibt es spezielle Vorgaben was Größe und Winkel betrifft. Zudem sind die Hersteller bei den Farbvarianten eingeschränkt, da gewisse Hightech-Gewebe nur eingeschränkt einfärbt werden können.

Pflege und Kontrolle
Schutzkleidung erfordert professionellen Umgang beim Waschen und regelmäßige Kontrollen, insofern möglich, auch der Schutzfunktionen. So muss die richtige Temperatur und Handhabung der Kleidung eingehalten werden, damit die PSA langfristig Sicherheit bietet. In der privaten Haushaltswäsche ist dies nicht umsetzbar. Insbesondere auch, da bei jeglichen Änderungen und Reparaturen stets mit Original- Materialien gearbeitet werden muss. Bei Workwear sind die Vorgaben weniger komplex, doch auch hier sollte auf eine fachgerechte Pflege geachtet werden.

Serviceanbieter CWS Workwear bietet im Bereich Arbeitskleidung und PSA Kleidung aus hochwertigen Materialien, die für Unternehmen gewaschen und professionell instandgehalten werden. So haben Arbeitgeber Gewissheit, dass die Arbeitskleidung ihrer Mitarbeitenden sauber und funktional bereitgestellt wird und bei Schutzkleidung alle Sicherheitsbestimmungen eingehalten werden. Denn der Serviceanbieter übernimmt mit der Textilübernahme auch die Verantwortung.

When the nonwoven industry meets at the leading trade fair INDEX in Geneva from 18 to 21 April, Mahlo GmbH + Co KG awaits trade visitors from all over the world to inform them about the right measurement technology enabling more efficient and high-quality production of nonwovens.

With a wide range of sensors, different measuring techniques and the corresponding measuring bridges, practically all tasks regarding the control of basis weight, moisture, thickness, fibre content, and air permeability can be solved in a cost-efficient and practical way.

As an example, Wulbeck mentions spunlace products. They mainly consist of fibres such as cotton, PE, PET or rayon. They absorb light in the near-infrared range. Water and all other materials have different spectral ranges and can thus be distinguished. The near-infrared sensor Infrascope NIR determines the moisture content and the basis weight of different materials by attenuating the light in certain wavelengths. Due to its very high spectral resolution, the sensor can distinguish between components with very similar but not identical IR absorption and achieves high measurement accuracy. "Up to 0.05 g/m2 of the respective coating weight is possible," says Wulbeck.

"We want to support manufacturers in optimising their production processes and thus also the end product," says Matthias Wulbeck, Mahlo product manager for QCS. Because, like many other industries, the nonwoven sector is struggling with challenges such as rising prices for energy and raw materials, long delivery times and uncertain supply chains. In order to continue to produce economically and on time, it is therefore necessary to save resources and avoid faulty production as well as unnecessary process times. "Our Qualiscan QMS measurement and control system helps to do just that."

• Iconic 200 Series fleece to be the first fabric made from this new process.

Polartec®, a Milliken & Company brand, announces Polartec® Shed Less Fleece, a new milestone in its industry-leading efforts to reduce textile fiber fragment shedding. Shed Less is a process that combines yarn construction, knitting, chemistry, and manufacturing to reduce home laundry fiber fragment shedding by an average of 85%. The first fabric to receive this new technology is the brand’s iconic Polartec® 200 Series Fleece, the modern version of the original PolarFleece® launched in 1981, and in 1993, the first performance fleece knit from yarn made from recycled plastic bottles.

The Shed Less process works by engineering the lofted fibers that give fleece its soft hand the ability to resist breaking and rubbing off during home laundering, cited as one contributing factor to the spread of fibers fragments (commonly referred to as microfibers). Polartec® Shed Less Fleece achieves this while maintaining all of the attributes that continue to make Polartec fleece a staple of midlayer collections - lightweight, breathable and warm.

The brand used the AATCC (American Association of Textile Chemists and Colorists) TM212-2021 test method for fiber fragment release during home laundering. This test was conducted with large sample sizes to account for variability. The testing concluded that Shed Less Fleece reduced fiber fragment shedding by an average of 85% compared to the baseline fabric.

“In 2016 we began looking into how we might test for fiber loss because there wasn’t a lot of research on the issue.” said Aimee LaValley, Polartec Textile Development, Dye and Chemistry Manager. “This led to new products like Polartec Power Air™, new manufacturing processes, as well as our participation in the TextileMission workgroup to study the issue on an interdisciplinary basis.”

TextileMission was a three year collaborative initiative of academia and industry to reduce the impact of textile microplastics funded by the German Federal Ministry of Education and Research. Founding partners include The Association of the German Sporting Goods Industry, Hochschule Niederrhein - University of Applied Science; TU Dresden - Institute of Water Chemistry; Vaude Sport; WWF Germany; Adidas AG; Henkel AG; Miele & CIE; and Polartec, LLC.

Polartec® Shed Less Fleece will be initially launched in the United States and will be available to customers beginning March 1, 2023. The brand plans to apply the Shed Less process to many other industry-leading fabric platforms and manufacturing facilities around the world.

This elevated status in 53 countries translates to CELLIANT being an ideal partner for global companies who are seeking innovation in textiles to distinguish their products.   

“We have laid the groundwork for our partner brands to capitalize on the benefits of our infrared technology and to enhance their ability to do business,” said Seth Casden, Hologenix co-founder and CEO.  “We firmly believe that regulatory status matters and that is why we have grown the number of countries we have such relationships with by over a third in the last three years. It is definitely a competitive advantage of our company and CELLIANT.”

“Globally, the awareness of the benefits of infrared textiles, which absorb body heat and reflect it back as therapeutic infrared energy, has grown exponentially over the last 10 years,” continued Casden. “And in the United States infrared is gaining a strong foothold.”

Majocchi, an Italian textile manufacturer, reports that it has achieved functional and visual appeal with its key fabrics since installing Baldwin Technology Co. Inc.’s corona surface treatment technology.  

Based in Tavernerio (Como), Majocchi has a history of being a technological innovator in the textile industry. Within a decade of its conception in 1941, Majocchi became a global supplier of waterproof cotton for rainwear manufacturers. In the 1960s, the company began producing nylon and technical fabrics, which paved the way for it to become a leading provider of textiles for urban fashion, technical workwear and the military today.

Majocchi has partnered with U.S -based Baldwin Technology Co. to utilize its unrivaled corona surface-treatment technology to produce superior wettability and adhesion.  

Corona treatment is a technique that temporarily modifies a substrate’s surface tension  properties. The corona oxidation process improves the penetration and absorption of liquids on cellulosic and synthetic fabrics. Utilizing corona treatment before resin application on fabrics such as lycra and nylon facilitates superior adhesion and resin distribution. As a result, corona-treated fabrics provide exceptional color and tonal quality.  

Majocchi uses Baldwin’s Corona Pure Model to apply polyurethane and acrylic-based coatings to its fabrics. The system allows Majocchi to administer a controllable, uniform coating to achieve the desired functionality and aesthetics.

The system is 2,000 millimeters wide with a discharging station and four ceramic electrodes designed for textile applications with the flexibility of customizing plasma dosage for a given fabric structure, width and process speed. The Corona Pure model allows for fabric treatment up to 300 gr/m² in thickness. The system is customizable, with single-sided and dual-sided treatment capabilities. The “Easy Change” feature allows for a seamless replacing of electrodes and rapid cleaning and removal of fiber and dust residue, maintaining optimal exhaust air flow. The treatment system is built with a swiveling housing mechanism, which provides clearance for changes in textile thickness and protects the ceramic electrodes.

The AVK Working Group SMC/BMC and the European Alliance for SMC BMC are jointly organising SMCCreate 2023 - a conference on designing with SMC and BMC composites. The event, which offers insights into the entire product design process from idea to part manufacture, is aimed at both experienced designers and those new to the use of these materials.
