DITF: Modernized spinning plant for sustainable and functional fibres

The German Institutes of Textile and Fiber Research Denkendorf (DITF) have modernized and expanded their melt spinning pilot plant with support from the State of Baden-Württemberg. The new facility enables research into new spinning processes, fiber functionalization and sustainable fibers made from biodegradable and bio-based polymers.

In the field of melt spinning, the DITF are working on several pioneering research areas, for example the development of various fibers for medical implants or fibers made from polylactide, a sustainable bio-based polyester. Other focal points include the development of flame-retardant polyamides and their processing into fibers for carpet and automotive applications as well as the development of carbon fibers from melt-spun precursors. The development of a bio-based alternative to petroleum-based polyethylene terephthalate (PET) fibers into polyethylene furanoate (PEF) fibers is also new. Bicomponent spinning technology, in which the fibers can be produced from two different components, plays a particularly important role, too.

Bicomponent spinning technology, in which the fibers can be produced from two different components, plays a particularly important role, too.

Since polyamide (PA) and many other polymers were developed more than 85 years ago, various melt-spun fibers have revolutionized the textile world. In the field of technical textiles, they can have on a variety of functions: depending on their exact composition, they can for example be electrically conductive or luminescent. They can also show antimicrobial properties and be flame-retardant. They are suitable for lightweight construction, for medical applications or for insulating buildings.

In order to protect the environment and resources, the use of bio-based fibers will be increased in the future with a special focus on easy-to-recycle fibers. To this end, the DITF are conducting research into sustainable polyamides, polyesters and polyolefins as well as many other polymers. Many 'classic', that is, petroleum-based polymers cannot or only insufficiently be broken down into their components or recycled directly after use. An important goal of new research work is therefore to further establish systematic recycling methods to produce fibers of the highest possible quality.

For these forward-looking tasks, a bicomponent spinning plant from Oerlikon Neumag was set up and commissioned on an industrial scale at the DITF in January. The BCF process (bulk continuous filaments) allows special bundling, bulking and processing of the (multifilament) fibers. This process enables the large-scale synthesis of carpet yarns as well as staple fiber production, a unique feature in a public research institute. The system is supplemented by a so-called spinline rheometer. This allows a range of measurement-specific chemical and physical data to be recorded online and inline, which will contribute to a better understanding of fiber formation. In addition, a new compounder will be used for the development of functionalized polymers and for the energy-saving thermomechanical recycling of textile waste.

Mit der Inbetriebnahme der neuen Polyestergarn-Produktion bei Garden Silk Mills in Surat, Indien, zeigt das zur Schweizer Oerlikon Industriegruppe gehörende Unternehmen Oerlikon Barmag seine Kompetenz als einer der führenden Anbieter von Chemiefaseranlagen. Der Um- und Neubau der Polyesterspinnerei mit 216 WINGS FDY Spinnstellen ging einher mit einer umfangreichen Engineering-Leistung, die im engen Zusammenspiel der Experten aus Deutschland und aus Indien erbracht wurden.

Das Expansionsprojekt für FDY-Garne bei Garden Silk Mills Private Limited (GSMPL) markiert den Beginn einer Periode schnellen Fortschritts im Textilsektor durch die Chatterjee Group (TCG) unter der Führung ihres Vorsitzenden Dr. Purnendu Chatterjee. Mit ihrer modernen Produktionsanlage in Jolwa, in der hochwertige Polyesterchips, POY, FDY und andere Spezialgarne hergestellt werden, und der Marke Garden Vareli, die eine zeitgemäße Kollektion von Saris und Kleidungsstoffen anbietet, schafft die Chatterjee Group, die weltweit Investitionen in Höhe von 8 Milliarden US-Dollar tätigt, den ,Garten von morgen‘. „Wir bei MCPI und GSMPL sind entschlossen, die textile Vision von Dr. Purnendu Chatterjee, dem Vorsitzenden von TCG, zu verwirklichen", sagte D.P. Patra, Whole Time Director und CEO von MCPI.

Oerlikon Barmag Anlagen beherrschen nahezu alle Prozesse zur Herstellung textiler und technischer Garne und verspinnen die gängigen Polymere Polyester, Polyamid 6 und 6.6 oder Polypropylen. Bei Garden Silk Mills geht es um vollverstreckte Garne (FDY). Sie werden ohne weitere Veredelung zu textilen Flächen verarbeitet. Überall dort, wo Textilien glatt fallen oder aber gleiten soll, kommen vollverstreckte Garne zum Einsatz.

Das WINGS Konzept durchbricht dabei die Grenzen konventioneller FDY Spinnanlagen. WINGS steht für optimierte Produktionsprozesse, geringe Abfallraten und um rund 30 Prozent reduzierten Energieverbrauch. Hohe Garnqualität ist dabei verpflichtend. Einsetzbar ist diese Technologie im FDY Prozess für Polyester und Polyamid.

Oerlikon Barmag WINGS Technologie unterstützt Garden Silk Mills bei der Produktion von FDY Premiumgarnen – leistungsstarke Spinnereikomponenten wie Spinnpumpen, Spinnbalken und Düsenpakete bis zur Crossflow-Anblasung und den 216 WINGS Wicklern wurden im Direktspinnverfahren im Anschluss an eine bei Garden Silk Mills vorhandene Polykondensationsanlage installiert.

  • 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.

Mit Partnern und Tochtergesellschaften wie Oerlikon Barmag Huitong Engineering (OBHE) und Barmag Brückner Engineering (BBE) legt Oerlikon Polymer Processing Solutions entsprechende Konzepte vor.

BCF Technologie: 6800 dtex mit RoTac³ tangeln
Hochflorige Teppiche oder Teppiche für den Outdoorbereich liegen aktuell im Trend, die Nachfrage nach diesen margenstarken Garnen steigt signifikant. Die hierfür benötigten dicken BCF Garne aus PP, PET oder PA6 lassen sich ab sofort mit der RoTac³ tangeln. Beim sogenannten Fachen werden alle drei Fäden gemeinsam durch eine Tangelöffnung in der RoTac³ geführt und miteinander vertangelt. So lassen sich Tangelknoten deutlich gleichmäßiger setzen als mit anderen marktüblichen Tangeleinheiten, auch bei hohen Produktionsgeschwindigkeiten. Häufige Tangelaussetzer werden vermieden. Das sorgt für eine bessere Garnqualität und wirkt sich positiv auf den Weiterverarbeitungsprozess aus. Das Ergebnis ist ein sichtbar ebenmäßigeres Erscheinungsbild des Teppichs. Zusätzlich wird der Druckluftverbrauch je nach Garntyp um bis zu 50% reduziert.

Das 3-in-1 plying Paket ist optional für die BCF Anlagen S+ und BCF S8 mit RoTac³ erhältlich und kann auch auf Wunsch nachgerüstet werden.

Oerlikon Barmag celebrates its 100th anniversary

  • 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.

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.”

Oerlikon: Less waste with the Smart Factory

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.

Recycling rückt in den Fokus

Müllberge, plastikverseuchte Meere, CO2 Footprint – die Notwendigkeit einer nachhaltigeren Lebensweise ist alternativlos. Logisch, dass Recycling Lösungen in der Textilindustrie zunehmend an Bedeutung gewinnen. Aufgegriffen hat das auch der erste virtuelle Global Fiber Congress in Dornbirn mit einer eigens auf das Thema fokussierten Session. Vor rund 400 Teilnehmern referierte auch Markus Reichwein, Leiter Produktmanagement bei Oerlikon Manmade Fibers, zu auf dem Markt verfügbaren Lösungen.

Als einer der einzigen Hersteller bietet das Segment Manmade Fibers des Oerlikon Konzerns die gesamte Kette des mechanischen Recylings von der Aufbereitung des Rezyklats zur Schmelze bis hin zur texturierten Spule. Dabei greift das Unternehmen auf die VacuFil Lösung seines Tochterunternehmens Barmag Brückner Engineering (BBE) zurück, die neben bottle-to-bottle und bottle-to-textile Prozessen auch die Verarbeitung von textilen Abfällen zu Chips beherrscht. Damit wird der Betrieb von Textilproduktionen im Sinne der Zero Waste Philopsophie möglich.

VacuFil sorgt für stabilen Prozess recycelter Qualitätsgarne
Wesentlich für einen stabilen und effizienten Spinnprozess und ausgezeichneter Garnqualität ist die zuverlässige Entfernung von Verunreinigungen. Gleichzeitig sind stabile Betriebsbedingungen mit möglichst minimalen Schwankungen essentiell. Die größte Herausforderung hierbei sind die unterschiedlichen Qualitäten der eingespeisten bottle flakes, da der Extrusionsprozess diese Schwankungen kaum ausgleichen kann. Hier steuert das VacuFil Konzept mit Mischsilos gegen. Damit werden die Unterschiede in der Viskosität der Polymere deutlich reduziert, so dass eine hohe Garn- und Gewebequalität garantiert ist.

Das VacuFil Konzept ist einer POY-Anlage von Oerlikon Barmag vorgeschaltet, die mit der rezyklierten Schmelze gewohnt hochwertiges Filamentgarn produziert. Als Texturierungslösungen bietet Oerlikon Barmag seine modernsten Anlagen der automatischen eAFK-Serie an, darunter auch die neueste Generation der eAFK Evo, die letztes Jahr auf der ITMA Barcelona vorgestellt wurde. Garnhersteller, die weiterhin manuell texturieren möchten, können auf die eFK-Serie zurückgreifen.

Mit VarioFil R+ steht Herstellern kleinerer Chargen zudem eine Kompaktanlage mit integrierter Rezyklataufbereitung zur Verfügung. Die Anlage bietet ein spezielles Extrusionssystem für Bottle-Flake Materialien, die neueste Dosier-und Mischtechnologie für Spinnfärben und eine erweiterte 2-Stufen-Schmelzefiltration. Die vier Spinnpositionen sind jeweils mit einem Oerlikon Barmag 10-end WINGS POY Wickler bestückt.

Ist das mechanische Recycling bereits sehr ausgereift, stellt das chemische Recycling für Mischgewebe die Textilindustrie noch vor große Herausforderungen. An Lösungen und Konzepten, aus diesen Geweben neue Textilien gewinnen zu können, arbeitet das Segment Manmade Fibers des Oerlikon Konzerns.

Recycling becomes a focus

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.
