From the Sector

Die Belastung der Umwelt mit Schadstoffen ist ein großes Problem, die sich in Luft, Böden oder Gewässern anreichern und nur mühsam zu beseitigen sind. Dazu gehören PFAS (Perfluoralkylchemikalien), schwer abbaubare Chemikalien, die in sehr unterschiedlichen Produkten vorkommen. So werden damit beispielsweise Textilien beschichtet, die für Outdoor-Kleidung Verwendung finden, um sie vor Feuchtigkeit zu imprägnieren. PFAS sind aber auch in Backpapier, Skiwachs sowie Kosmetika wie Wimperntusche, Make-up und Lippenstiften vorhanden.

Auch in Feuerlöschern kamen PFAS bis vor Kurzem zum Einsatz. Mittlerweile sind sie EU-weit verboten, sodass die vorher damit ausgerüsteten Anlagen rückstandsfrei gereinigt werden müssen. Betriebe, die Schaummittel-Löschanlagen haben, müssen für den Brandfall gerüstet sein, andererseits besteht aber die Pflicht, Geräte und Anlagen rückstandslos von PFAS zu befreien.

Die NT Service GmbH mit Sitz in Steinhöfel bietet die Dekontamination von Schaummittel-Löschanlagen, insbesondere hinsichtlich PFC/PFAS-Rückständen und übernimmt für Kunden die Umwelthaftung.

Together with the German circular knitting machine builder Mayer & Cie., Groz-Beckert has developed the optimized Relanit sinker SNK F over the past years. Independently of this, the development of the new LCmax™ energy-saving needles took place. The focus of both developments is on efficiency, energy savings and increased process reliability.

Groz-Beckert offers interested machine builders different cooperation options to jointly develop new products or optimize existing ones. The Groz-Beckert Technology and Development Center (TEZ) provides the appropriate framework for so-called co-development projects. At the ITMA in Milan in June 2023, Groz-Beckert presented some of the successful cooperations under the motto "Innovation through cooperation". Among them were two new developments realized with Mayer & Cie. Groz-Beckert presented the two new products for the first time in Asia at ITMA Asia in November 2023.

Optimized Relanit sinker SNK F
At the end of 2018, circular knitting machine manufacturer Mayer & Cie. approached Groz-Beckert with a request to jointly develop an improved and more efficient sinker for selected machines of their Relanit family that would run more smoothly and reliably in the needle tricks. The innovative sinker has an integral spring with a spring force that is adapted to the sinker thickness. Field tests were consistently successful and confirmed the functionality and advantages of the new sinker.

Thanks to their adapted spring, the newly developed SNK F Relanit sinkers are securely guided while they are running through the cam track, resulting in a quieter operation. This increases process reliability and ensures an improved loop structure. In addition, wear on the swivel butts of the sinkers is reduced. This increases service life and makes the process more sustainable and cost-efficient.

Higher energy efficiency thanks to LCmax™
The objective second recent cooperation with Mayer & Cie. was to develop a cost-effective energy-saving needle. After considering various variants, the common choice of Mayer & Cie. and Groz-Beckert was the LCmax™ knitting machine needle with innovative, wave-shaped shank geometry. The first prototypes were extensively tested on laboratory machines at Groz-Beckert's TEZ.

The wave-shaped shank of the LCmax™ needle ensures a smaller contact area of the needle in the needle trick. This results in less friction, which reduces machine temperature and enables energy savings of up to 20 percent compared to a standard needle. This saves costs and at the same time allows operation of the machine at the maximum possible speed.

In both projects, the cooperation between Mayer & Cie. and Groz-Beckert went far beyond mere product development. In addition to Applications Engineering and Construction, the companies' Sales and Purchasing departments were also involved in a close exchange.

Gerade in der kalten Jahreszeit wird beim Outdoorsport Wert auf Kleidung gelegt, die Körperwärme speichert. Der Lagenlook ist hier besonders sinnvoll. Neben einem funktionalen Baselayer, der temperaturausgleichend und feuchtigkeitsleitend ist, dient die zweite Schicht, der sogenannte Midlayer, als Isolationsschicht. Je nach Kältegrad, Aktivitätsniveau und persönlichem Temperaturempfinden sind unterschiedliche Midlayer empfehlenswert.

Merinoexperte Smartwool bietet mit seinen Smartloft und Intraknit Produkten passende Midlayer für moderate bis bewegungsintensive Aktivitäten sowie für kühles bis kaltes Wetter. Sie lassen viel Bewegung zu und transportieren Schweiß ab, um den Körper auf Betriebstemperatur zu halten.  Die verantwortungsvoll gewonnene Merinowolle ist wärmend, temperaturausgleichend und gleichzeitig geruchsneutralisierend.

Die hochisolierenden, nachhaltigen Smartloft Produkte halten den Körper bei Kälte zuverlässig warm, ohne dass er zu warm wird. Die leichtgewichtige Isolation auf der Front, bestehend aus teilweise recycelter Wolle und feinen Synthetikfasern, spendet uneingeschränkte Wärme. Dehnbares und weiches Fleece aus Merinomischgewebe sorgt für Bewegungsfreiheit und Tragekomfort. Nicht nur die Wolle, auch die Kunstfaser ist zum großen Teil recycelt. Die Merinowolle ist Mulesing-frei und ZQ- zertifiziert.

Der US-amerikanische Merinospezialist Smartwool wurde 1994 von einer Gruppe Skifahrern gegründet, die einfach nur warme Füße auf der Piste haben wollten. Nach mehreren Experimenten mit verschiedenen Materialien fiel die Wahl auf Merinowolle. Als natürliches Funktionsmaterial vereint diese Wolle alle gesuchten Eigenschaften: Sie ist weich, feuchtigkeitsableitend, thermoregulierend (warm bei Kälte und kühl bei Hitze), nachhaltig, geruchsneutralisierend und trägt sich extrem gut auf der Haut. Zudem ist Merinowolle extrem langlebig, so dass alle Kleidungsstücke bedenkenlos in der Maschine gewaschen werden können.

Felix Pohlkemper and Tim Röding from Institut für Textiltechnik (ITA) of RWTH Aachen University are developing a technology with their start-up CarboScreen GmbH that makes complex carbon fibre production controllable through sensor monitoring. With the help of CarboScreen technology, it should be possible to double the production speed from the current 15 m/min to 30 m/min in the medium term. The doubling of production speed alone could result in an increase in turnover of up to €37.5 million per year and production plant. Felix Pohlkemper and Tim Röding were awarded third place in the AVK Innovation Award 2023 in the Processes and Procedures category for this ground-breaking development. The award ceremony took place during the JEC Roof Forum in Salzburg, Austria.

The production of carbon fibres is highly complex. In the current state of the art, however, the manufacturing process is only monitored manually by semi-skilled workers. However, even minimal fibre damage during production leads to a reduction in the quality of the carbon fibre. In extreme cases, it can also lead to plant fires. To ensure production quality, the production speed is currently limited to a maximum of 15 m/min. In fact, the production speed of the systems could be higher. The sensor-based online monitoring of Carbo-Screen makes it possible to increase the production speed to 30 m/min in the medium term. As a result of the increased production volume per system, the specific production costs of the carbon fibre are reduced, which can result in lower prices.

A reduced sales price would make it possible to use carbon fibres and their composite materials even more widely in traditional markets such as aerospace technology and wind energy, as well as for mass production in the automotive industry.

The CarboScreen online monitoring system is currently being developed for industrial use. It is to be validated at an industrial plant in 2024. CarboScreen GmbH was founded as part of EXIST funding and offers AI-supported sensor systems for carbon fibre production. The sensor technology continuously monitors the fibre throughout the entire production process. Deviations are detected automatically.

The winners of the AVK Innovation Award are honoured annually by the AVK Industrievereinigung Verstärkte Kunststoffe. Companies, institutes and their partners are honoured in three categories: products and applications, processes and procedures, and research and science.

RUDOLF HUB1922 makes a move in response to the escalating demand for genuinely sustainable technologies, particularly from forward-thinking segments within the textile and apparel industry. In a showcase at Denim by Premiere Vision Milan, RUDOLF HUB1922 presents a pioneering range of textile chemistry that embodies true evolution.

This chemistry marks a milestone in addressing the pressing need for sustainable solutions. By harnessing raw materials derived from organic waste, plastic waste, and renewable feedstock, RUDOLF's latest textile innovations stand poised to transform the industry, promising a substantial reduction in its environmental footprint.

Alberto De Conti, Head of RUDOLF HUB1922, emphasizes the radical nature of evolutionary textile chemistry, stating, "RUDOLF's approach tackles the challenge of waste generation head-on by transforming waste materials into valuable resources". The diversion of waste and renewable feedstock away from landfills and incinerators to fuel textile chemical production is a game-changer, that diminishes the industry's reliance on non-renewable resources and endorses a circular economy model.

The successful integration of chemicals derived from organic and plastic waste, as well as renewable feedstocks, necessitates effective communication and education. Herein lies the significance of fostering collaborative efforts within the industry. De Conti underscores this point, stating, "Collaboration among scientists, fashion designers, and manufacturers is paramount. It propels a collective shift towards sustainable practices, making eco-friendly fashion the standard and minimizing the industry's environmental impact".

HeiQ introduces a 100% biobased and long-lasting cosmetic finishing technology for textiles to the market. The newest addition to the HeiQ portfolio harnesses the power of active probiotics and selected prebiotics to enhance the skin microbiome, turning the human’s largest organ into the best-looking one.

HeiQ Skin Care is a synbiotic textile finish aimed at providing a balanced microbiome for glowing skin, even after repeated use and washing of textiles. Unlike conventional products, HeiQ Skin Care utilizes slow-release prebiotics and probiotics seamlessly integrated into a biobased textile matrix, enriching the skin's microbiome diversity, and offering long-lasting cosmetic benefits.

The synergistic combination of prebiotics and probiotics, known as synbiotics, delivers a soothing cosmetic skin treatment while relaxing, working, or sleeping. Probiotics not only restore and improve the skin's natural balance but also enhance its self-repair capabilities. Synbiotics promote skin renewal, rebalancing, and improved appearance, reducing the signs of aging and establishing a favorable environment for the skin's natural repair mechanisms.

A second skin that takes care of the first
The skin, the largest organ in human body, is home to a diverse community of microorganisms called the skin microbiome. It plays a crucial role in maintaining good skin condition, acting as a protective barrier against harmful agents. However, various factors, such as hormones, diet, smoking, environmental exposures, and excessive UV radiation, can disrupt its balance, leading to skin conditions like rashes, acne, psoriasis, rosacea, skin irritation, redness, eczema, and odor. Maintaining a balanced skin microbiome is essential for preserving skin integrity.

HeiQ Skin Care is suitable for all textile fibers, both natural and synthetic, and can be applied to all textile items that come in direct contact with the skin. This versatility makes it an ideal choice for daily use- at work, during sports, leisure activities, or as bedding items like bed sheets and pillows.

Intensive wear trials conducted during the development stage have proven the consistent release of synbiotics (prebiotics and probiotics) onto the skin, creating conditions to foster a well-balanced microbiome.

In cooperation with the Swiss company Haelixa, Oerlikon Manmade Fibers Solutions will, in future, be able to make the entire value chain of a textile end product transparent and hence sustainable. The two development partners are offering a solution for the comprehensive traceability of products, as required by the European Green Deal.

An essential part of the solution is the DNA marker technology developed by Haelixa that enables complete traceability of materials. These markers survive all production process steps, validating that the end product is identifiable. "This innovative technology employs distinct DNA tailored for each project, establishing a unique identity for the material," explains Holly Berger, Marketing Director at Haelixa. "Once the DNA is integrated into the material, it becomes irremovable, impervious to falsification or alteration." Handling is straightforward: the DNA marker is fed into the spinning process with the preparation oil, for example. The preparation system is modified accordingly. Further feeding options are currently being developed.

Smart factory: total transparency with atmos.io
The concept is complemented by atmos.io, Oerlikon's digital platform, which records and evaluates extensive production and process data during the yarn manufacturing process. Atmos.io gives the yarn its digital identity during its time on Oerlikon systems, from the melt to the packaged package. This technology has been used successfully for some time to monitor the production process. With atmos.io, deviations in process parameters and yarn data can be identified and rectified within a very short time, which in turn keeps the yarn quality stable and reduces waste rates.

Combining both technologies enables clear traceability of the yarn produced, even in the downstream process steps. Hence, the yarn's components, qualities, manufacturing conditions, and origin are traced beyond doubt in the finished garment. "The unique DNA carries the 'roots' of the yarn digitally recorded in atmos.io into the everyday life of the end consumer," says Jochen Adler, CTO at Oerlikon Manmade Fibers. The textile end products meet the requirements of the digital product passport required by the EU, which contains the information needed to assess their life cycle assessment and circularity. Initial long-term tests have shown 100% traceability of the yarns in the POY and FDY spinning process. If the yarn manufacturer relies on the atmos.io platform, production systems can be adapted relatively easily to use the DNA markers.
