From the Sector

• 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.

• 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.”

Over 400 employees work hard every day to improve the environmental performance of Radici Yarn’s site. Through teamwork and continuous improvement in energy efficiency, Radici Yarn has obtained ISO 50001 Energy Management Systems certification, which attests to the organization’s commitment to contain and progressively reduce energy consumption.

Radici Yarn, one of the companies in the RadiciGroup Advanced Textile Solutions Business Area, is engaged in the production and sale of polyamide 6 polymer, PA6 and PA66 continuous filament and staple yarn, and other synthetic fibres, including products made of recycled or bio-based materials.

All the processes - polymerization and spinning (Villa d'Ogna plant), as well as warping and draw-warping (Ardesio plant) - are run under constant monitoring with the goal of achieving maximum energy efficiency and lower consumption. Both sites are powered by two hydroelectric power plants owned by Geogreen, a RadiciGroup partner and energy supplier. The share of energy consumption from renewable sources and reduced environmental impact (natural gas) sources  is constantly increasing.

The energy issue has always been a priority for Radici Yarn, whose products serve numerous sectors, including automotive, clothing and furnishings.

"Already at the beginning of the 1990s, Radici Yarn started investing in cogeneration, the simultaneous production of electricity and steam,” pointed out Laura Ravasio, energy manager of Radici Yarn SpA. “We have recently started up an advanced trigeneration plant – a highly efficient system that produces not only electricity and steam, but also chilled water for our production processes. One of the first results recorded in 2021 was a 30% reduction in water consumption. Thus, ISO 50001 certification seemed like the next logical step to take in formalizing a long-term approach to energy.”

The ISO 50001 certification, which is voluntary and valid for a period of three years, was added to the ISO 14001 Environmental and ISO 9001 Quality Management system certifications previously achieved by Radici Yarn.

The Hygiene Fibers Group of Indorama Ventures (IVL) came together at the Index Show to present an all-inclusive range of recycled and biodegradable solutions for Hygiene Fiber and Nonwoven applications.

The combination of polymers, technologies, processes and global reach supported by the Hygiene Fibers Group – one of three business segments that make up Indorama Ventures – positions it within the Hygiene industry to meet increasingly challenging market demand for innovative sustainable solutions within the hygiene sector. Across the six brands and companies that make up Hygiene Fibers Group – Auriga, Avgol, FiberVisions, Indorama Asia, Trevira and Wellman International – sustainability and supporting customers to achieve circular objectives is integral to all efforts and fundamental to the ethos of the Hygiene business segment.

At the Index Show, the Hygiene Fibers Group launched CiCLO®, a textile technology which allows polyester and other synthetic materials to biodegrade like natural materials do in wastewater treatment plant sludge, sea water and landfill conditions, reducing synthetic microfiber pollution generated during washing, and minimizing plastic accumulation in landfills caused by discarded textiles.

In line with the company’s commitment to support customers with high performance products, while also reducing the impact on the environment, several of the  Hygiene Fibers brands, including Wellman International, Trevira GMBH and Auriga, have been working closely over the last 12 months with the IAM team and the CiCLO® technology. Developments have focused on PET and rPET staple fiber and filament sustainable solutions for applications where recycling is particularly challenging, such as Hygiene, Home Textiles and Automotive applications.

Strengthening the profile of biodegradable offerings within the Hygiene Fibers Group’s sustainability portfolio, Trevira introduced a new range of bicomponent fibres based on PLA and PBS (polybutylene succinate) at the Index show. Both biopolymers offer an exceptional technological opportunity in terms of environmental care and sustainability, while delivering optimum performance. Equally to PLA, PBS is recyclable and up to 100% biodegradable under industrial conditions.

Efforts towards supporting customers to achieve circular objectives are a priority within the Hygiene Fibers Group. This is reflected in the recycled fibers expertise deployed across the segment. Four Hygiene Fibers Group brands, IVL Asia, Auriga, Trevira and Wellman International offer an extensive range of 100% recycled, accredited PET fibers, across a multitude of fiber and nonwovens applications.

The development and evolution of sustainable technologies is central to activity across IVL’s Hygiene Fibers Group, with particular focus on sustainable polyolefin solutions. FiberVisions and ES-FIBERVISIONS, leading Polyolefin mono and bico fiber brands and sister company Avgol, have partnered with UK-based Polymateria to commercially harness the innovative ‘biotransformation’ technology pioneered by Polymateria. The patented technology alters the properties of polyolefins to make them biodegradable in a natural process.  Other polyolefin sustainable innovations within the Hygiene Fibers Group were featured at Index include biosurfactant and biocolourant developments being undertaken by the Avgol team with FiberVisons progressing sustainable design solutions, including lightweight, high performance, reduced carbon solutions.

• New brand Trevira CS eco

After a challenging 2020 for Trevira CS®, a year in which the coronavirus crisis put pressure on the contract market, in particular on the hotel and event sector, and also on the cruise shipping industry, the market is starting to show some signs of improvement. Numerous new developments are seizing upon the trends that have emerged since the crisis began.

Although the coronavirus pandemic had a negative effect on individual business sectors, it also has the potential to open up new market opportunities for flame retardant Trevira CS fabrics in the long run. The increase in people working from home and the longer and more frequent stay within one’s own home have led to a change in perspective in terms of the relevance of interior design. The design of the living space has undergone a revaluation. Sustainability, durability, high quality, and the desire for safe products that contain little to no harmful substances are defining criteria for selecting a new textile interior. The colour range of the new Trevira CS developments is directed specifically towards this trend and often comes across as discreet and close to nature. After Trevira CS products have found their way more and more into private homes, the new Trevira CS collections include numerous attractive textiles not only for the contract sector but also for the residential sector.

In the contract sector, notably in the hotel industry, the trends towards sustainability and quality are likely to continue to grow. Moreover, there is an increase in awareness as far as hygiene requirements are concerned. Textiles that are easy to clean without losing their appearance or their functionality can excel here. Accordingly, products ordinarily used in the healthcare sector might start to be of interest to the hotel and catering industry, public spaces, the transport industry, and to offices. This will apply in particular to areas where there is a regular flow of visitors and where people come into direct contact with fabrics. Antimicrobial textiles provide additional protection in these situations. Besides their flame retardancy, many new Trevira CS products integrate additional functions such as noise or sun protection.

Trevira has launched the Trevira CS eco brand for flame retardant textiles that consist of recycled Trevira products.
The new Trevira CS eco brand unites sustainability and flame retardancy. Trevira offers products for this which have been manufactured through different recycling processes. The flame retardant filament yarns are based on the use of recycled PET bottles (post-consumer recycling). Textiles bearing the Trevira CS eco trademark consist of at least 50% recycled materials.

Trevira uses an agglomeration facility to recycle reusable waste materials from production to manufacture recycled fibres that, after further processing, retain the same quality and performance characteristics as the original products (pre-consumer recycling).

• PrimaLoft and Origin Materials have launched a program to develop high-performance, carbon-negative insulating fibers for diverse apparel applications, including for leading outdoor, fashion, and lifestyle brands, as well as home goods applications such as hypoallergenic insulated bedding.
• PrimaLoft, an advanced material technology company and a world leader in the development of high-performance insulations and fabrics, will develop the fibers with Origin Materials to address demand for sustainable, high-performance materials from its over 900 global brand partners. PrimaLoft iconic brand partners include Patagonia, Stone Island, L.L. Bean, Lululemon, adidas and Nike.
• The program will focus on carbon-negative PET and next-generation polymers produced by the Origin Materials patented technology platform, which turns sustainable wood residue into cost-advantaged, carbon-negative materials that reduce the need for fossil resources.

Origin Materials, Inc. (“Origin Materials”), a leading carbon negative materials company, and PrimaLoft, an advanced material technology company and a leader in the development of high-performance insulations and fabrics, announced a new program to develop carbon-negative, insulating, high-performance fibers. The fibers will be used across a diverse array of end products, including insulating fiber for leading outdoor, fashion, and lifestyle brands, as well as home goods applications such as hypoallergenic insulated bedding.

The companies will work to rapidly develop and commercialize new products derived from Origin Materials’ platform. The collaboration will leverage the leadership position of PrimaLoft as a specialty producer of insulating fibers and filaments with over 900 global brand partners, as well as a large global network of manufacturers that employ a wide array of textile processes to make its products, including extrusion, carding, spinning, finishing, weaving, knitting, dyeing, airlaid, meltblown, and other technologies.

The collaboration builds on PrimaLoft’s “Relentlessly Responsible™” mission to elevate both performance and sustainability, through innovation. The platform includes PrimaLoft® Bio™, which was developed and launched into the market in late 2018 as an effort to battle microplastics in the ocean; PrimaLoft® P.U.R.E.™, which provides materials manufactured with greater than 50% CO2 savings; and PrimaLoft’s post-consumer recycling initiative. The next frontier for the company is non-petroleum based raw materials, including products that biodegrade and other circular economy solutions.

A typical manmade fiber system produces well over 600 tons of yarn a day. This equals in around 700 winders in filament yarn production or 3 systems in staple fiber production. These figures show just how important smooth production processes are.

If an error creeps into the process at any point, the daily waste increases dramatically. It is obvious that all yarn manufacturers want to prevent this happening to ensure their production facilities operate efficiently. Here, digitalization provides invaluable support. A Smart Factory that networks all steps within the production chain – including all auxiliary processes – identifies and reports quality deviations at an early stage. Yarn manufacturers can quickly intervene in the production process and hence avoid generating waste.

Digital solutions ensures process reliability
And the Smart Factory is also the focus of Oerlikon Manmade Fibers. Here, it comprises considerably more than the Plant Operation Center, a system that has been well-established within the market for many years now. “This is about absolute transparency and traceability. At the end of the process, yarn manufacturers are able to track at which position its finished textured yarn packages were spun and even have information on the processed granulate and the specific production conditions”, comments Ivan Gallo, responsible for digital products at Oerlikon Manmade Fiber. In this way, the Smart Factory ensures process reliability, above all. The data are automatically entered into the system and the product assessed at each stage of yarn production at which values and data are recorded – such as during visual inspection and when weighing. In the event of anomalies in the intermediate laboratory and quality checks, this allows yarn producers to intervene in the production process and correct these anomalies.

Information on the chip feeding, on the drying and on the masterbatch are available, as are data on the climate control, on the compressed air supply and on further auxiliary systems. With this, yarn manufacturers have at all times a complete overview of the ongoing production process, including comprehensive information on quality and production costs.

Mountains of waste, plastic-infested oceans, negative CO2 footprints – the need for more sustainable ways of living has never been more urgent. Consequently, it is logical that recycling solutions are becoming increasingly important within the textile industry. This was also tapped into at the first virtual Global Fiber Congress in Dornbirn with a session that focused specifically on the topic. In front of around 400 participants, Markus Reichwein, Head of Product Management at Oerlikon Barmag, also spoke about solutions currently on the market.

As one of only manufactureres, the Oerlikon Group’s Manmade Fibers segment offers the entire mechanical recycling chain –from preparing the recycled materials, producing the melt all the way through to the textured package. Here, the company utilizes the VacuFil solution supplied by its subsidiary Barmag Brückner Engineering (BBE) –which, in addition to mastering bottle-to-bottle and bottle-to-textile processes, is also able to process textile waste into chips. This permits the running of textile production operations very much in line with the zero-waste philosophy.

VacuFil ensures a stable process in the case of recycled quality yarns
The reliable removal of contaminants is vital for a stable and efficient spinning process and outstanding yarn quality. At the same time, stable operating conditions with minimal fluctuations are essential. The greatest challenge here is the differing qualities of the bottle flakes fed into the system, as the extrusion process is barely able to balance these fluctuations. Here, the VacuFil concept counters with blending silos, which reduce the differences in the viscosity of the polymers considerably and guarantee high yarn and fabric quality.

The VacuFil concept is installed upstream to an Oerlikon Barmag POY system, which transforms the recycled melt into filament yarn of the accustomed high quality. As texturing solutions, Oerlikon Barmag offers its state-of-the-art automatic eAFK-series systems, including the latest generation of the eAFK Evo, which was unveiled at the ITMA Barcelona last year. Yarn manufacturers wishing to continue texturing manually can use the eFK series.

With the VarioFil R+, producers of smaller batches now also have a compact system with an integrated recycled materials preparation unit at their disposal. The system offers a special extrusion system for bottle flake materials, the very latest metering and mixing technology for spin-dying and expanded 2-stage melt filtration. The four spinning positions are each equipped with an Oerlikon Barmag 10-end WINGS POY winder.

While mechanical recycling has already been extensively developed, chemical recycling for mixed fabrics is still presenting the textile industry with huge challenges. The Oerlikon Group’s Manmade Fibers segment is currently working on solutions and concepts for transforming these fabrics into new textiles.

wear2wear is an innovative industrial partnership dedicated to high-quality and sustainable clothing. Five expert partners in Europe have come together to cover the entire recycling loop. On cutting-edge production systems, textile fibres from used clothing will be turned into functional fabrics. Schoeller Textil AG is supplying a wholistic textile portfolio for the workwear area. At Schoeller Textil, the recyclable, functional fabrics from the wear2wear concept belong to the Inspire fabric group. These are high-quality protective workwear fabrics made of 100 percent polyester, which offer the greatest clothing comfort and often feel just like cotton. They are also compliant with the stringent requirements of the bluesign® system.

The sustainable wear2wear concept is synonymous with high-quality, responsible clothing. In European operations, textile fibres from used garments are used to produce new functional fabrics. Depending upon the area of intended use, they also meet strict waterproofing, breathability, protection and comfort requirements. To ensure that the raw material cycle comes full circle, these textiles can be recycled again when they reach the end of their service life. As a result, there is no waste, and they go on to produce new garments. As the wear-2-wear partner companies guarantee that – from the quality of the raw materials to the guaranteed recycling end process – these are 100 percent recyclable, functional fabrics made of recycled textile fibres. Water- and dirt-repelling technologies based on renewable raw materials, along with the most advanced membrane technology, will ensure that the textiles are manufactured and impregnated entirely without the use of PFC in the future too.

Five partner companies  
The five European partner companies in the wear2wear cooperation cover the entire recycling loop. Heinrich Glaeser Nachfolger GmbH is a German fibre and yarn producer and the “recycler” in the loop. Märkischen Faser GmbH (D) is the “upcycler” and fibre manufacturer. Carl Weiske GmbH & Co. KG (D) develops the polymers, fibres, yarns, chemical additives and textile systems, and TWD Fibres GmbH (D), a fully-integrated filament yarn producer, covers the entire range of polyester and polyamide 6.6 continuous filament yarns. Schoeller Textil AG, the innovative Swiss company, is responsible for textile production and manufactures sustainable high-tech fabrics with maximum clothing comfort. The matching climate-neutral and similarly 100 percent recyclable PTFE and PFC-free membrane, as well as recycled outer materials and linings, are supplied by Sympatex Technologies (D), the ecological alternative among the textile function specialists. DutchSpirit is a Dutch company which has been dedicated to environment-friendly clothing since 2010. Its mission is to significantly increase the awareness for sustainable clothing and offer recyclable clothing in the workwear segment. DutchSpirit is the initiator for the development of the Inspire products from Schoeller Textil and provided the inspiration for the wear2wear concept. Further garment-making partners who now also belong to the cooperative group include: Anchor Workwear BV (NL), Hüsler Berufskleider AG (CH), Groenendijk Bedrijfskleding BV (NL), Bedrijfskledingdiscounter BV (NL) and Rifka'S (NL).

• Market success above expectations
• Product and market development accelerated
• Investment up to EUR 30 mn

Lenzing – The Lenzing Group is setting another milestone as a specialist for extremely high-quality products made of the renewable raw material wood. Capacities will be significantly expanded due to strong demand for Lenzing’s TENCELTM Luxe filament yarn which was first launched on the market just a few months ago. Lenzing will invest up to EUR 30 mn in a further pilot line at the Lenzing site. Basic engineering for construction of the new facility has already been initiated.

“Thanks to TENCELTM Luxe, Lenzing is currently positioning itself in the premium luxury market and is embedding the issue of sustainability there in combination with superior aesthetics”, says Robert van de Kerkhof, Chief Commercial Officer of the Lenzing Group. “The fine filament yarn is comparable to natural silk due to its airy feeling on the skin and the matte finish. It is perfectly suited for very fine fabrics made exclusively from this yarn and as a blending partner with silk, cashmere and wool”, he adds.

“On the occasion of the launch of TENCELTM Luxe filaments, the luxury brands already realized what opportunities they would have by using this yarn made of the renewable raw material wood. For this reason, demand is already so high that we have decided to take an intermediate step to expand capacities before building a large commercial production plant. The decision to construct a new line will serve as the basis for generating a three-fold increase in capacity compared to the previous volume. The additional capacity will be available to customers at the end of next year”, states Stefan Doboczky, Chief Executive Officer and Chairman of the Management Board of the Lenzing Group. “The Lenzing site was selected because research and technological know-how in plant construction are connected in a special way, which will in turn enable us to further develop this special product”, Doboczky adds.

The new capacities will enable Lenzing to more effectively fulfil the needs of customers for TENCELTM Luxe filament yarn than in the past. At the same time, Lenzing will press ahead with technical planning for a large-scale commercial line at the Lenzing site.

This strong level of demand is further evidence of the Lenzing Group’s innovative strength. The yarn is opening up new markets for the company in the eco-couture segment, thus contributing to the successful implementation of the sCore TEN strategy.
