From the Sector

Oerlikon has invited all visitors to this year's Shanghaitex in China on a journey into the future of manmade fiber production. From 25 to 28 November 2019, the world market leader showed all its guests its vision of a sustainable and automated manmade fiber production at its 100 m² stand in Hall E1, D20: "Clean Technology. Smart Factory." was the motto of the future. And this was only a stone's throw away from reality at the stand. Because today Oerlikon was presenting the four ITMA Barcelona world premieres for efficient machine and plant concepts in a new, innovative industrial design. Together with numerous other innovations, all this forms the new DNA of the Oerlikon Manmade Fibers segment.

Launched to create new standards in texturing: the eAFK Evo generation of machines promises superior speeds, greater productivity and consistently high product quality, along with lower energy consumption and simpler operation vis-à-vis comparable market solutions. Oerlikon Barmag showed these wideranging capabilities at the trade fair with a high-end design from the new system platform. In particular, the numerous value-added features include two that are excelling with cool technology: the optimized EvoHeater and the EvoCooler, a completely newly-developed active cooling unit.

At home, at work, on the street, in the sky, on the water, even in space, technical textiles and nonwovens are swinging towards ever higher performances in amazing applications. Versatile and light, but sometimes stronger than metal, these materials of the future gain their superpowers from the interaction of precisely coordinated textile systems. At Techtextil in Frankfurt am Main from May 14 to 17, 2019 in Hall 3, B06, Oerlikon will be showing chemical fiber applications made of polyester, polypropylene and Co. and what they can do in these fields. However, these exhibits are only a communicative means to an end, as Oerlikon is primarily interested in placing the associated machinery and plant solutions at the centre of discussions with trade fair visitors.

More than two thirds of all technical innovations are directly or indirectly based on new materials, says the German Research Ministry. One could add: The key to a more advanced world, for technological products with amazing functions, breathtaking performance and greater environmental benefits, is also to improve the properties and processing of materials. This applies first and foremost to textiles. Probably no other fabric is so strong as a "team player" who draws its strength from its cohesion. A single polyester thread, for example, looks inconspicuous. Processed into a thigh-thick special weave, however, high-strength High Modulus/High Tenacity fibers anchor floating oil platforms in the deepest waters. These kilometer-long "Mooring Ropes" withstand a breaking load of well over 1,000 tons and perform their task better than steel. For decades, Oerlikon Barmag has been offering special solutions for the production of so-called industrial yarns (IDY) that are tailored to customers worldwide. "We will once again be presenting numerous innovations at this trade fair to inspire our customers," explains Dr.-Ing. Dipl.-Chem. Roy Dolmans, Technology Manager IDY and R&D Filament Processing.

Die IDEA, die vom 25. – 28. März in Miami Beach, Florida USA, stattfindet, begann für Oerlikon Nonwoven mit einem Vertragsabschluss. Der Kunde, ein renommierter Meltblown Spezialist aus Europa, investiert in eine Zwei-Balken Meltblown Anlage vom Neumünsteraner Anlagenbauer, um seiner stark steigenden Nachfrage durch diese Kapazitätserweiterung gerecht zu werden. Auf der Anlage sollen zukünftig Meltblown Vliese für eine Vielzahl von Anwendungen, insbesondere aus dem Filtrations- und Wipesbereich, produziert werden. Der kommerzielle Produktionsstart ist für die erste Jahreshälfte 2020 geplant. Der Markt für Meltblown Vliese wächst durchschnittlich mit 6% im Jahr.

• Innovative BCF S8 platform technology opens up new carpet yarn industry markets for Oerlikon Neumag customers

World premiere at the DOMOTEX World Trade Fair for Carpets and Floor Coverings in Hanover: between January 11 bis 14, 2019‎, Oerlikon Neumag will be showcasing its innovative new development, the BCF S8, to a wide audience for the very first time in Hall 11, Stand B36. Whether commodities or niche products – the new BCF S8 platform technology offers manufacturers of BCF carpet yarns decisive arguments for responding to constantly rising cost pressures and the trend for greater efficiency and quality in fiercely-competitive markets. World record: the system achieves never-seen-before spinning speeds and is able to simultaneously spin up to 700 filaments and produce fine titers of up to 2.5 dpf. This superlative performance is guaranteed by numerous individual innovations in the new platform and, for the first time, also in a new human-machine interface (HMI)-based control system, which opens the door to the digital age of smart carpet yarn manufacturing wide. At the ITMA ASIA 2018, the Oerlikon Manmade Fibers segment had already announced that it would be presenting revolutionary solutions in 2019 – both in hardware and software. And the DOMOTEX marks only the start.

According to manufacturer information, the new BCF S8 is the most efficient Oerlikon Neumag BCF system of all times. “We have succeeded in achieving a new level of greater productivity and even broader product diversity. These allow our clientèle to better cater to changing market requirements and achieve a competitive edge in tough market conditions”, explains Martin Rademacher, Vice President Sales Oerlikon Neumag. As a pre-taste, the machine specialists from Neumünster are serving up performance figures and results from comprehensive trials conducted at their own BCF technology center as well as from two pilot systems which have been tried and tested within the market for months now.

BCF S8 performance in numbers
With up to 700 potential filaments per yarn end, the BCF S8 is raising the benchmark considerably compared to the Oerlikon Neumag S+ BCF system (400 filaments) that has dominated the global market to date. Oerlikon Neumag guarantees fine titers of up to 2.5 dpf. Furthermore, the process speed is higher than ever before – 3,700 m/min (winder speed). This permits throughputs of up to 15 percent greater compared to predecessor technologies. Overall, system efficiency is 99 percent – almost unbeatable. True to the Oerlikon Segments Manmade Fibers segment e-save philosophy, energy savings of up to 5 percent per kilogram of yarn are achievable.

BCF S8 innovations – from straight yarn paths to large cooling drums

This comprehensive progress has been achieved with numerous smart innovations. To this end, one key element above all has been optimized. The yarn path from the spinning system to the new, large cooling drum has now been almost completely straightened. This yarn path, unique to the BCF market to date, ensures that the individual filaments are subjected to minimum friction, hence once again considerably reducing yarn breaks and optimizing the overall production process. Especially noteworthy here are the, for the first time, straight yarn inlet in the texturing head – guaranteeing superior yarn quality.

And the considerably reduced distance between the heating godet duo and the texturing head also has a positive impact on the texturing process. It ensures a more even twist to the yarn and reduces the compressed air consumption. Furthermore, the texturing chambers can be removed individually, which additionally shortens servicing times. The now closed units also provide the best possible protection for the texturing jets and lamellar chambers.

The 800-mm diameter cooling drum optimally and gently cools the filaments. And this has a positive influence on the yarn quality. The new cooling drum is now equipped with a V groove for all polymers (PET, PA6 and PP) as standard.

The RoTac3 tangling unit, already established within the market, once again reduces the compressed air consumption by around 50%, while the newly-developed Witras III-37 winder achieves production process speeds of 3,700 m/min.

First intuitively-operable human-machine interface (HMI)
The new BCF S8 is the first Oerlikon Manmade Fibers segment system equipped with the innovative human-machine interface (HMI) for intelligent controlling and monitoring. In this case, the interface between man and machine has been oriented on the daily requirements of users in BCF production. With its new ‘look and feel’, it supports intuitive operation and offers direct access to important information as well as actual and target values at each take-up position by means of a touch screen. A completely new ‘alarm philosophy’ also simplifies troubleshooting and malfunction analysis. “This smart HMI system is a logical step in the digitalization of our products”, explains Dr. Friedrich Lennemann, Vice President R&D Oerlikon Neumag.

The market for the production of carpet yarn is increasingly evolving towards more demanding processes. However, beyond commodity products, standard plants can no longer fully exploit their advantages. From 20th to 22nd March 2018, Oerlikon Neumag will be presenting an economical alternative in Shanghai in hall W3, booth F03 at the Domotex asia/Chinafloor, the leading floor covering trade fair in the Asia-Pacific region: the BCF plant Sytec One with single-end technology.

If the requirements for the production of BCF yarns increase, for example, from recycled polyester or fine filaments, then this can also lead to higher breakage rates. Highly standardised production plants must then often strike compromises with regard to throughput, quality or cost-efficiency. In such cases, the Sytec One offers a good solution instead of the mostly three-end technology plants for standard processes.

Single-end technology with 98% productivity

This BCF plant works with only one yarn (end) per position, making it ideal for demanding production processes. The reason: when a yarn break occurs only one yarn tears, all other yarns continue to run. This not only simplifies troubleshooting, it also reduces the re-threading time. In addition, less waste is produced. As a result, the productivity of the Sytec One is still over 98% for ten breakages a day, while a plant with three-end technology only reaches around 92%.

Faster processes due to a straight yarn path

In addition, the absolutely straight yarn path of the Sytec One enables significantly higher process speeds of up to 15% in spinning and texturing processes compared to multi-end technologies. Higher total titers of up to 6,000 dtex can also be produced without any problems. The gentle yarn guidance also ensures minimum friction on the individual filaments. This means less yarn breaks and a more stable process.

Optimised key component: spinning pack

Last but not least, the engineers at Oerlikon Neumag have developed a new design for the spinning pack. This central component of every BCF machine significantly influences the yarn quality. The corresponding solution for the Sytec One optimises the polymer flow in the spin pack, thus reducing the polymer dwell time. This leads to shorter product and colour change times and increases the plant efficiency. In addition, the spinning packs were widened so that yarns with up to 500 filaments can now be produced.

The product mix is decisive

In view of these advantages, the single-end Sytec One is recommended for processes with high breakage rates, fine filaments, frequent colour changes or in general when demanding processes take up an increasing share in the business. "The product mix is decisive for the choice of technology," sums up Alfred Czaplinski, Sales Manager BCF at Oerlikon Neumag. "We are happy to advise on the optimal solution and offer both single-end and three-end plant technologies." 

Good business at the Domotex Hanover, Germany

In the run-up to the trade fair, the Domotex Hanover in mid-January was already proving to be a promising harbinger. With four lively trade fair days and contract conclusions in the lower double-digit million euro range, mainly from the European and Asian markets, the order intake for Oerlikon Neumag was very good.

Ob kleben, vergießen oder dämmen, dichten und schäumen - auf der diesjährigen Bondexpo, der internationalen Fachmesse für Klebtechnologie informiert Oerlikon Barmag über sein Zahnraddosierpumpenprogramm speziell für die Arbeitsschritte Fügen/Verbinden. Vom 9. bis zum 12. Oktober präsentiert das Unternehmen in Halle 6 unter anderem Komponenten für die Silikonverarbeitung sowie Heißschmelzkleberanwendungen, aber auch für die Verarbeitung von Harzen oder Polyurethanen und anderen höherviskosen Flüssigkeiten (Standnr. 6422).

Effizienz in der Bewältigung zähflüssiger Medien – die GA-Baureihe
Beim Auftrag von Heißschmelzklebern steht vor allem die Gleichmäßigkeit des Auftrags im Vordergrund. Exaktes Dosieren setzt aber nicht nur das schnelle und reproduzierbare Einstellen eines Betriebspunktes voraus, sondern auch eine pulsationsarme Einspeisung des Fördermediums. In Ergänzung zur bewährten GM-Baureihe hat Oerlikon Barmag nun die GA-Serie zur Förderung höherviskoser Medien entwickelt. Die GA-Baureihe ist in Fördervolumina von 1,25 – 30 cm³/U (0,6-144 l/h) lieferbar. Sie ist ausgelegt für Drücke bis 200 bar, für Viskositäten bis 1.500 Pas sowie für Temperaturen bis maximal 225°C. Mit der neuen Pumpenbaureihe bietet Oerlikon Barmag überall dort maßgeschneiderte Lösungen, wo auf eine genau definierte, gleichmäßige Dosierung Wert gelegt wird.

Austrag und Dosieren aus einer Hand – die Fasspumpe
Die Fasspumpe ist speziell zur Förderung und Dosierung hochviskoser Materialien wie Klebstoffe, Silikone etc. aus Fässern und anderen großen Gebinden und für Drücke bis zu 250 bar ausgelegt. Thorsten Wagener, verantwortlicher Sales Mitarbeiter für Pumpen in industriellen und chemischen Anwendungen: "Die Fasspumpe trägt nicht nur hochviskose Materialien aus dem Fass aus, sondern dosiert das Medium ohne einen weiteren Zwischenstopp mit dem gewohnt hohen volumetrischen Wirkungsgrad zum Mischkopf.“ In enger Abstimmung mit dem Kunden werden Zahnradpumpe und Fassfolgeplatte so aufeinander abgestimmt, dass die Platte mühelos den Boden des Behälters erreichen kann und so nur eine sehr geringe Restmenge von < 1% zurücklässt, was sich positiv sowohl auf die Materialkosten als auch auf den Produktionsablauf auswirkt.

Unter Hochdruck arbeiten
In der Hochdrucktechnologie stellt die Förderung von kleinen Durchsätzen mit niedrigen Viskositäten eine besondere Herausforderung dar. Speziell für diesen Einsatz hat Oerlikon Barmag die GM-Baureihe mit rundem Plattenpaket um eine Option hinsichtlich Druckaufbauvermögen erweitert. Diese mehrstufige Pumpe ist in den Fördergrößen 0,05 bis 20 ccm/U lieferbar und gewährleistet den Aufbau hoher Betriebsdrücke selbst bei niedrigen Viskositäten (z.B. 250 bar, 100 mPas). So lassen sich höhere volumetrische Wirkungsgrade bzw. ein größerer nutzbarer Drehzahlbereich erzielen. Die robuste Zahnraddosierpumpe sorgt für einen pulsationsarmen kontinuierlichen Betrieb. Somit können erstmalig auch Anwendungen im Hochdruckbereich abgedeckt werden, die minimale Durchflussraten (z.B. 0,5g-1,5g/sec.) fordern. Für die Hersteller von PUR-Formteilen, Blockschaum, Kühlmöbelisolationen oder Sandwichpanels bedeutet das konstante Prozessstabilität bei geringeren Investitionskosten.
 
Eine für alle – High-Speed Dosieren leicht gemacht
Die neue High-Speed-Dosierpumpe ist speziell für schlecht schmierende und abrasive Medien entwickelt worden. Mit ihrem vergrößerten Drehzahlbereich (30 – 500 U/min) deckt sie einen großen Austragsbereich ab, für den bisher mehrere Pumpen unterschiedlicher Größen eingesetzt werden mussten. Für den Produzenten bedeutet das geringeren Aufwand bei Produktionsumstellungen und weniger Ersatzteilhaltung. Die kompakte Bauweise der Pumpe (ø65mm) verringert den Platzbedarf in der Maschine und das geringe Gewicht (1,4 kg) hält die Belastung so niedrig wie möglich, was sich wiederum positiv auf die Bauweise der Maschine auswirkt. Die lebensdauergeschmierten außenliegenden Kugellager sorgen bei der Pumpe nicht nur für eine lange Lebensdauer, sondern werden auch nicht vom jeweiligen Produkt berührt.
