From the Sector

• New yarns for the contract furnishing world, for industrial sewing threads and the challenge of biodegradable polyester

At the product level, big impulse has been given to the range of industrial sewing threads for various uses, with new references both in the polyester + polyester compositions as well as in cotton + polyester. The industrial threads, marketed as raw material, allow the company to consolidate its position on some strategic markets, such as in Germany.

As a result of the partnership with Trevira® for the spinning of the flame-retardant Trevira^®CS fibre, Filidea Technical Yarns reinforces its offer of non-dyed performant yarns aimed at the world of contract furnishings. The sector of hospitality, of furnishings for public and work spaces, fairs and areas for social-cultural gatherings will find a comprehensive answer to its demands in the Trevira^®CS-based yarns: with regard to fireproof standards, versatility, resistance to wear and tear, excellent colour rendering, and last but not least, the component of fibre sustainability, an essential value for the design of spaces for collective use.

Continuing in the development of sustainable production across the sector, the company has undertaken two important initiatives with other actors in the textile supply chain. Filidea participates in Trick, the European blockchain project – part of the European Horizon 2020 programme – involving 29 partners from six different nations to reinforce the circular economy thanks to the development of a digital platform which is complete, traceable and available to operators in the textile sector.

MagnoLab, the network of enterprises in the textile supply chain, and of which Filidea is one of the founding members, gives the impulse to constant R&D activities. MagnoLab was established in 2022 in order to develop tangible solutions for the sector, to create values and to collaborate with regard to current and future demands.

MagnoLab brings together textile companies which are active at various stages of and with complementary roles in the supply chain, and which work in synergy and share objectives, resourcefulness and long-sightedness, with the aim of developing innovation in a structured way. MagnoLab is also open to welcome new partners.

Wissenschaftler:innen vom Institut für Textilmaschinen und Textile Hochleistungswerkstofftechnik (ITM) der TU Dresden sind am 21. Juni 2022 für ihre gewebten Herzklappenimplantate mit dem Techtextil Innovation Award 2022 in der Kategorie „New Product“ ausgezeichnet worden.

Im Rahmen eines Forschungsprojektes der Industriellen Gemeinschaftsforschung (IGF) entwickelten Wissenschaftler:innen des ITM neuartige textile Herzklappenprothesen. Die Implantate können exakt an die anatomische Form angepasst und minimalinvasiv im Herz platziert werden. Die textile Herzklappe ist integral gefertigt. Hierbei erfolgt die Integration des Ventils in situ während des Webprozesses. Somit besteht die strömungstechnisch optimierte Herzklappe aus einer einzigen textilen Struktur. Weitere Fügeprozesse, z. B. durch Nähen, sind nicht mehr erforderlich. Das reduziert den Fertigungsaufwand im Gegensatz zur heutigen Herstellung biologischer Herzklappenprothesen in Handarbeit enorm.

Prof. Chokri Cherif, Institutsdirektor des ITM, freut sich mit seinem Team sehr über die kontinuierli-chen interdisziplinären Forschungserfolge, die am ITM in enger Kooperation mit technischen Webereien, Medizinern und Anwendern stetig erzielt werden. „Bereits vor zwei Jahren wurden wir mit dieser neuartigen Entwicklung als eines der drei Finalistenteams des Otto von Guericke-Preises 2020 geehrt. Die Auswahl für den Techtextil Innovation Award 2022 ist eine erneute Bestätigung für den Bedarf an unserer praxisorientierten Forschung und eine besondere Würdigung, aber gleichzeitig auch weiterer Ansporn für die zeitnahe Umsetzung unserer Forschungsergebnisse in die Industrie.“

Bislang stehen für die Behandlung defekter Herzklappen mechanische und biologische Klappen zur Verfügung. Die neuartigen gewebten Herzklappenprothesen sollen die Vorteile der beiden Typen vereinen: unbegrenzte Lebensdauer, keine lebenslange Einnahme von blutverdünnenden Medikamenten und minimal invasive Operation. Ferner können die textilen Herzklappen zeit- und kostensparend mit hoher Reproduzierbarkeit und Qualität gefertigt werden.

• Target markets: automotive, furnishings, sports and technical apparel
• New product entry: radipeople® line of personal protective equipment

RadiciGroup is at Techtextil 2022, the leading European trade fair for technical textiles, taking place in Frankfurt am Main, Germany, from 21 to 24 June. On display in the RadiciGroup exhibition area are the Group’s latest products for the automotive, furnishings and apparel markets: from nylon and polyester yarn, including biosource and recycled lines, to nonwovens and the new radipeople® line of personal protective equipment (PPE).

Indeed, at Techtextil, RadiciGroup is showcasing RENYCLE®, a yarn obtained from recycled nylon; REPETABLE®, a polyester yarn from post-consumer recycled plastic bottles; RESPUNSIBLE®, a nonwoven fabric from recycled polypropylene; and BIOFEEL®, a brand identifying a yarn line obtained from renewable sources of both nylon and polyester.

Moreover, RadiciGroup is participating in a forum organized by the Technical Textiles Section of Sistema Moda Italia in collaboration with the Italian Space Agency (ICE) (Hall 12.1 – Stand C58), with the goal of introducing product innovations not only coming from a single manufacturer, but also from an innovative synergistic approach all along the supply chain, from raw materials to finished products. An example of this synergistic collaboration is the “Mars Spacesuit”, recently tested in the USA by analogue astronauts as part of a space medicine project designed to measure the vital signs of future astronauts and develop technologies to support the simulation of life in space and planetary environments. RadiciGroup teamed up with major Italian textile companies and supplied the materials to make the suits for the six analogue astronauts participating in the mission and coordinated the development of the technologies needed to create the technicalwear for use in extreme environmental conditions.

Natural fibers are among the most important raw materials in the textile and fashion industry worldwide. For centuries, they have fed millions of people through their cultivation or breeding, and it is impossible to imagine daily life without them. Especially at the moment, natural fibers are gaining special importance due to the intense discussions about sustainable living. Even though natural fibers have accompanied mankind for a long time, they are changeable, technical, and adaptable to the challenges of the textile industry.

The Discover Natural Fibres Initiative (DNFI) is celebrating natural fibres in a program to be conducted during Heimtextil in Frankfurt on 23 June. Anyone with an interest in the role of natural fibres in the world economy, economic indicators of textile activity, innovations in natural fibre research, and updates on proposed EU legislation affecting textiles is welcome to attend.

The program will include various presentations by the previous and current award winners, presentations, and discussions:

Overview of world natural fibre production, employment, and value,

• Economic indicators and impacts of coronavirus on textile industries,
• Updates on innovative uses of natural fibres:
• Use of wool in automobile insulation applications for enhanced sustainability,
• Using cellulose from cotton to produce a biodegradable plastic substitute,
• Manufacturing waterproof fabric from a blend of cotton and jute as sustainable
• Substitute for polypropylene tarps
• Proposed EU textile legislation and potential impacts on natural fibres

The European Pultrusion Technology Association (EPTA) has published a report from its latest conference, which focuses on advances in sustainability and recycling.

More than 130 professionals from the global pultrusion community gathered at the 16th World Pultrusion Conference in Paris on 5-6 May 2022. Organised by EPTA in collaboration with the American Composites Manufacturers Association (ACMA), the event featured 25 international speakers sharing insight on market trends, developments in materials, processing and simulation technologies, and innovative pultruded applications in key markets such as building and infrastructure, transportation and wind energy.

‘Bio-pultrusion’:  
Composites based on natural fibres offer a number of benefits, including low density and high specific strength, vibration damping, and heat insulation. The German Institutes for Textile and Fiber Research Denkendorf (DITF) are developing pultrusion processes using bio-based resins and natural fibres. Projects include the BioMat Pavilion at the University of Stuttgart, a lightweight structure which combines ‘bamboo-like’ natural fibre-based pultruded profiles with a tensile membrane.

Applications for recycled carbon fibre (rCF):
The use of rCF in composite components has the potential to reduce their cost and carbon footprint. However, it is currently used to a limited extent since manufacturers are uncertain about the technical performance of available rCF products, how to process them, and the actual benefits achievable. Fraunhofer IGCV is partnering with the Institute for Textile Technology (ITA) in the MAI ÖkoCaP project to investigate the technical, ecological and economic benefits of using rCF in different industrial applications. The results will be made available in a web-based app.

Circularity and recycling:
The European Composites Industry Association (EuCIA) is drafting a circularity roadmap for the composites industry. It has collaborated with the European Cement Association (CEMBUREAU) on a position paper for the EU Commission’s Joint Research Centre (JRC) which outlines the benefits of co-processing end-of-life composites in cement manufacturing, a recycling solution that is compliant with the EU’s Waste Framework Directive and in commercial operation in Germany. Initial studies have indicated that co-processing with composites has the potential to reduce the global warming impact of cement manufacture by up to 16%. Technologies to allow recovery of fibre and/or resin from composites are in development but a better understanding of the life cycle assessment (LCA) impact of these processes is essential. EuCIA’s ‘circularity waterfall,’ a proposed priority system for composites circularity, highlights the continued need for co-processing.

Sustainability along the value chain:
Sustainability is essential for the long-term viability of businesses. Resin manufacturer AOC’s actions to improve sustainability include programmes to reduce energy, waste and greenhouse gas emissions from operations, the development of ‘greener’ and low VOC emission resins, ensuring compliance with chemicals legislation such as REACH, and involvement in EuCIA’s waste management initiatives. Its sustainable resins portfolio includes styrene-free and low-styrene formulations and products manufactured using bio-based raw materials and recycled PET.

International textile producers meet again in Istanbul, Turkey, from June 14 – 18, 2022 on the occasion of the ITM + Hightex Exhibition. In Hall 9 (Hightex) the exhibitors will present the complete industry value chain from nonwovens raw materials, production machines and accessories to the endproduct. The related industries covered include hygiene, filtration, fabrics and apparel, medical, automotive, wipes, home furnishings and upholstery. DiloGroup offers tailor-made production systems from one supplier and will inform about its portfolio and the latest equipment developments from fibre opening to the finished felt.

DiloGroup will inform about complete lines as well as high speed needlelooms for spunbonds. A new, simplified elliptical needle beam drive makes Hyperpunch technology also attractive for standard application. Hyperpunch HαV allows a more uniform stitch distribution in the preneedling process especially in combination with the new needle pattern 6000X. In a complete needling line this felt homogenization process can be improved further. The new needle pattern 8000X is a milestone in the needle pattern development process and results in endproduct surfaces with low markings over a wide range of advances/stroke.

Another strong pillar of the sales program over decades has been fibre preparation and high speed webforming equipment for other nonwoven technologies. The further development of the high-speed layering principle “Hyperlayer” made progress for better CD strength through a combination of inline cards and crossline card with crosslapper. Particularly, carding machines in a working width above 3.5 m up to 5.1 m have been supplied by DiloSpinnbau as complete high speed carding systems, comprising two or even three cards in a line to directly feed the hydroentangling units of various suppliers. Together with DiloTemafa not only have high throughput rates been achieved in the fibre preparation section of the line but also dedusting filtering and air-conditioning systems have been successfully engineered and integrated.

Together with Sicam, Dilo has combined know-how for hydroentangling technology and therefore can provide complete lines as general contractor including equipment for cutting, winding and packaging.

Another interesting machine is the 3D-Lofter, first presented during ITMA 2019 in Barcelona, which offers a wider range of nonwovens applications by exploring the third dimension. A series of single web forming units which work according to the aerodynamic web forming principle deliver defined fibre masses in varied patterns on a base needlefelt. A stress oriented production of technical formed parts resulting in fibre savings or patterned DI-LOUR or DI-LOOP felts with or without repeat are two examples for this technology which explores new application areas for needlefelts.
The 3D-Lofter technology may also be used “inverted” as “IsoFeed” for filling up bad spots in web mats and thus achieves a better homogeneity of spunlace or airlay products.

The DiloLine 4.0 concept offer I4.0 modules which not only support the user but also facilitate quality control and maintenance by a maximum data transparency in production and control of operation. The Dilo solutions “Smart Start” for a fully automatic start of the production line or “DI-LOWATT” for energy savings are accompanied by Siemens solutions which can be selected via App or Data Cloud “MindSphere”.

• Sustainable infrastructure solutions, road safety and health protection

At this year’s Techtextil, Oerlikon Polymer Processing Solutions will be presenting the trade audience with new applications, special processes and sustainable solutions focusing on the production of industrial textiles. Among other things, the company will be showcasing new technology for charging nonwovens that sets new standards with regards to quality and efficiency. Between June 21 and 24, the discussions will be concentrating on airbags, seat belts, tire cord, geotextiles, filter nonwovens and their diverse applications.

More polyester for airbags
Airbags have become an integral part of our everyday automotive lives. The yarns used in them are made predominantly from polyamide. As a result of increasingly diverse airbag applications and also the increasing size of the systems used, polyester is today used as well, depending on the application requirements and cost-benefit considerations. Against this background, the Oerlikon Barmag technologies make an invaluable contribution. In addition to high productivity and low energy consumption, they particularly excel in terms of their stable production processes. Furthermore, they comply with every high quality standard for airbags, which – as in the case of virtually all other textile products used in vehicle construction – must provide the highest level of safety for vehicle occupants. And all this without any loss of function in any climate and anywhere in the world for the lifetime of the vehicle.

Buckle up!
Seat belts play a decisive role in protecting vehicle occupants. They have to withstand tensile forces in excess of three tons and simultaneously stretch in a controlled manner in emergencies in order to reduce the load in the event of impact. A seat belt comprises approximately 300 filament yarns, whose individual, high-tenacity yarn threads are spun from around 100 individual filaments.

Invisible, but essential – road reinforcement using geotextiles
But it not just inside vehicles, but also under them, that industrial yarns reveal their strengths. Low stretch, ultra-high tenacity, high rigidity – industrial yarns offer outstanding properties for the demanding tasks carried out by geotextiles; for instance, as geogrids in the base course system under asphalt. Normally, geotextiles have extremely high yarn titers of up to 24,000 denier. Oerlikon Barmag system concepts simultaneously manufacture three filament yarns of 6,000 denier each. Due to the high spinning titers, fewer yarns can be plied together to the required geo-yarn titer in a more cost- and energy-efficient manner.

hycuTEC – technological quantum leap for filter media
In the case of its hycuTEC hydro-charging solution, Oerlikon Neumag offers a new technology for charging nonwovens that increases filter efficiency to more than 99.99%. For meltblown producers, this means material savings of 30% with significantly superior filter performance. For end users, the consequence is noticeably improved comfort resulting from significantly reduced breathing resistance. With its considerably lower water and energy consumption, this new development is also a future-proof, sustainable technology.

New high-tech Staple Fiber Technology Center
Extending to around 2,100 m2, Oerlikon Neumag in Neumünster is home to one of the world’s largest staple fiber technology centers. As of now, these state-of-the-art staple fiber technologies are also available for customer-specific trials.

The focus during the planning and the design of the Technology Center was on optimizing components and processes. Here, special attention was paid to ensuring the process and production parameters in the Technology Center system could be simply and reliably transferred to production systems. Here, the fiber tape processing line is modular in design. All components can be combined with each other as required. And comprehensive set-up options supply detailed findings for the respective process for various fiber products.

The Technology Center is also equipped with two spinning positions for mono- and bi-component processes. The same round spin packs are used for both processes, characterized by excellent fiber quality and properties and meanwhile very successfully deployed in all Oerlikon Neumag production systems. Furthermore, the spinning plant is complemented by automation solutions such as spin pack scraper robots, for example.

Lenzing – In the first quarter of 2022, the Lenzing Group, like the entire manufacturing industry, was significantly affected by the extreme developments in global energy and commodity markets. A predominantly positive market environment and the strategic focus on specialty fibers such as those of the TENCEL™, LENZING™ ECOVERO™ and VEOCEL™ brands nevertheless ensured a solid revenue and earnings trend, with the effect of higher costs being largely offset.

•    Solid revenue and earnings performance despite extremely tight cost situation
•    Personnel changes on the Managing and Supervisory Boards – Stephan Sielaff appointed as the new CEO
•    Successful production start at world’s largest lyocell plant in Thailand
•    World’s largest pulp mill of its kind successfully started-up in Brazil
•    Premium textile brand TENCEL™ celebrates 30 years of sustainable fiber innovation

The Lenzing Interim Report 01-03/2022 is available on the company website.

• Innovation begins with creativity
• A pioneer of the manmade fiber industry

When the manmade fiber age began a century ago, a German company was responsible for the pioneering work involved. Barmag, established in 1922, was one of the world’s first companies to construct machines for the large-scale production of synthetic staple fibers. To this day, the leading manufacturer of manmade fiber spinning systems and texturing machines in Remscheid – a brand under the aegis of the Swiss Oerlikon Group since 2007 – has shaped technological progress in this sector; in future, with ever more innovations focusing on sustainability and digitalization.

Barmer Maschinenfabrik Aktiengesellschaft (Barmag) is founded in Barmen, located in the Bergische Land region, on March 27, 1922. The German and Dutch founders enter unchartered technological territory, one created as the result of a groundbreaking invention: in 1884, French chemist Count Hilaire Bernigaud de Chardonnet used nitrocellulose to produce the first so-called artificial silk, later known as rayon. The following decades see rapid development focusing on the search for synthetic textile fibers and their manufacturing technologies. As one of the first machine factories, Barmag battles its way through the eventful early years of the manmade fiber industry, the ‘Roaring Twenties’ and the Great Depression – and suffers the extensive destruction of its factories at the end of World War Two. Rebuilding is successful. With the unstoppable success story of purely synthetic plastic fibers such as polyamide, the company flourishes from the 1950s through to the 1970s, establishing sites in all international, for the textile industry at the time important, industrial regions and garnering prestige across the globe in the process. In the ups and downs of expansion, global competition and crises, Barmag reaches the very pinnacle of the market and becomes the preferred technological development partner for the manmade fiber industries in China, India and Turkey. The company has been a high-impact brand under the umbrella of the Oerlikon Group since 2007.

On the wings of innovation
Today, Oerlikon Barmag is a leading supplier of manmade fiber filament spinning systems and part of the Manmade Fibers Solutions business unit of the Oerlikon Polymer Processing Solutions Division. And our aspirations have not diminished: “The striving towards innovation and technological leadership has been, is and will always be part of our DNA”, emphasizes Georg Stausberg, CEO of Oerlikon Polymer Processing Solutions. In the past, this has been observable in such trailblazing innovations as the revolutionary WINGS generation of winders for POY in 2007 and WINGS for FDY in 2012. Currently, the focus of new and further developments is very much on digitalization and sustainability. Here, Oerlikon Barmag has – as one of the world’s first systems manufacturers – been implementing fully-networked smart factories for globally-leading polyester manufacturers since the end of the last decade. Within this context, digital solutions and automation are also helping to provide greater climate and environmental compatibility. This sustainability commitment is not only evidenced by the e-save label introduced for all products back in 2004: Oerlikon is endeavoring to also make all its sites carbon-neutral by 2030 and to acquire its energy exclusively from renewable sources. An ambitious target, whose achievement could be helped by the Oerlikon Barmag anniversary, states Georg Stausberg: “Innovation begins with creativity. And remembering the past provides plenty of motivation and inspiration for the future.”
