From the Sector

Neumünster/Troisdorf, Germany, December 3, 2020 – just a few days ago, the second newly-delivered Oerlikon Nonwoven meltblown system was commissioned at Innovatec’s state-of-the-art machine park. With it, the nonwovens manufacturer – based in Troisdorf in North Rhine-Westphalia – immediately started producing polypropylene filter nonwovens: in particular for use in protective face masks, which have been increasingly in demand since the start of the coronavirus pandemic and whose domestic manufacture is being supported by the Ger-man Government. Here, the highly-efficient Oerlikon Nonwoven meltblown technology from Neumünster is supporting the production of these highly-effective filter media.

“Back in June 2020, Oerlikon Nonwoven delivered the first so-called 2-beam system to Innovatec”, reports Rainer Straub, Head of Oerlikon Nonwoven. Together with the second production line, the Troisdorf-based enterprise has been able to almost double its filter nonwoven output to date. The North Rhine-Westphalian company now has filter media production capacities that can be used to manufacture up to 2.5 billion operating room filter masks or a billion highly-effective FFP2 masks per year.

The, according to its own information, leading manufacturer of meltblown mask nonwovens in Europe is participating in the German Government’s ‘Nonwovens Production’ grant program to ramp up its output capacities and has for this reason already received a visit from top German politicians, including Federal Minister for Economic Affairs Peter Altmaier and North Rhine-Westphalia Minister President Armin Laschet. Together, politicians and industry want to ensure that the production capacities for protective equipment continue to grow in Germany and that above all critical supply chains are secured at both national and European levels. And companies such as Innovatec and Oerlikon Nonwoven are actively contributing towards this.

Since the outbreak of the coronavirus pandemic, the worldwide demand for protective masks and apparel has resulted in a record number of new orders in the high double-digit millions of euros at Oerlikon Nonwoven. The meltblown technology from Neumünster is recognized by the market as being one of the technically most efficient methods for producing highly-separating filter media made from plastic fibers.

Protective equipment demands high-end nonwoven products
The rising demand for protective masks and other medical protective equipment since the start of the coronavirus pandemic and the associated global ramping up of production capacities has also resulted in an increase in the demand for nonwovens for the production thereof. Initially, this resulted in bottlenecks in the provision of meltblown filter nonwovens. To this end, there had until this point be very few producers of medical filter nonwovens outside China. Meanwhile, the demand for spunbond systems is also rising. “Due to the structure of our group, we are in the fortunate position to swiftly reallocate and free up our production capacities. This means that we are able to relatively quickly deliver not only meltblown systems, but also spunbond equipment”, explains Dr. Ingo Mählmann, Head of Sales & Marketing at Oerlikon Nonwoven, talking about the positive situation at the company.

The capacities for respiratory masks available in Europe to date are predominantly manufactured on Oerlikon Nonwoven systems. “Our machines and systems for manufacturing manmade fiber and nonwovens solutions enjoy an outstanding reputation throughout the world. Ever more manufacturers in the most diverse countries are hoping to become independent of imports”, comments Dr. Mählmann. The Oerlikon Nonwoven meltblown systems are being delivered to Germany, China, Turkey, United Kingdom, South Korea, Italy, France, North America and – for the very first time – to Australia until well into 2021.

Quality and efficiency in demand
Depending on the purpose of the application, medical PPE (personal protection equipment) should be breathable and comfortable to wear, protect medical staff against viruses, bacteria and other harmful substances and form a barrier against liquids. For these reasons, they are often made of either pure spunbond or of spunbond-meltblown combinations. Here, the meltblown nonwoven core assumes the barrier or filter task, while the spunbond has to retain its shape, while being tear-resistant, abrasion-proof, absorbent, particularly flame-resistant and nevertheless extremely soft on the skin.

All masks are not created equal – thanks to the ecuTEC+
Protection against infections such as coronavirus can only be guaranteed with the right quality.

The nonwovens can be electrostatically-charged in order to further improve the filter performance without additionally increasing breathing resistance. Here, Oerlikon Nonwovenʼs patented ecuTEC+ electro-charging unit excels in terms of its extreme flexibility. Nonwovens manufacturers can freely choose between numerous variation options and set the optimal charging method and intensity for their specific applications. In this way, even the smallest particles are still attracted and reliable separated by a relatively open-pored nonwoven. Nevertheless, mask wearers are still able to easily breathe in and out due to the comparatively loose formation of the fibers. To this end, it comes as no surprise that all meltblown systems currently destined for the production of mask nonwovens are equipped with the ecuTEC+ unit.

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.

The textile machinery industry is eagerly awaiting the start of the virtual trade show "Innovate Textile & Apparel". What and how will the more than 160 exhibitors present themselves virtually? How will the approximately 10,000 registered visitors accept the digital offer? WTIN is breaking new ground as organizer with this platform. But one thing is already certain: From 15 to 30 October 2020, they will bring the textile machinery industry a little closer together again in the Corona Pandemic. Oerlikon invites all visitors to take a look into the future of manmade fibers production and get to know the comprehensive range of products and services.

"Reconnecting innovation in the textile & apparel value chain" is the motto of WTIN's virtual trade show. And Oerlikon intends to more than live up to this motto. With more than 50 active experts from sales, customer service and technology as well as partners from its international network of representatives, the Manmade Fibers segment of the Swiss Oerlikon Group will try to be represented around the clock. "It is an interesting experiment for all of us and we would like to see it succeed," explains André Wissenberg, Head of Marketing, Corporate Communications and Public Affairs. "Our aim is to meet our existing customers again, make new contacts and see 'old friends' from the industry. We have prepared an attractive digital offer for them all. Those of you who missed our roller coaster ride in Barcelona last year can now enjoy the journey through time in peace and quiet from your home office on your digital tour of the fair. And, there are no more waiting times either," promises Wissenberg.

Factory know-how from a single source
From Melt to Yarn, Fibers and Nonwovens. From the polycondensation and the processing of PTA and MEG as well as the extrusion of, for example, recycled polyester chips all the way through to hundreds of thousands of packaged and stored or directly-delivered textured bobbins for a market within the textile industry worth billions. From the planning and construction of highly complex production plants to the engineering of large-scale plant projects and competent customer services. This business model runs like a red thread through the self-conception of the Manmade Fibers segment of the Swiss Oerlikon Group. The right partner, especially – but not exclusively – for newcomers to the textile industry. "With us they get everything they need for a successful business: Factory know-how from a single source. And that's what we would like to show our visitors at our virtual trade fair booth," says Wissenberg.

Retrofitting a wiping robot to spinning systems is well worthwhile. This is confirmed by the experiences of those customers who have already installed the wiping robot. Oerlikon Barmag wiping robots have been cleaning spin packs at filament yarn manufacturing facilities in China and India for several months now, increasing efficiency considerably.

Regular wiping of the spin packs is important for process stability and yarn quality. These can be positively influenced using wiping robots, because – as confirmed by data acquisition and analysis at the respective manufacturing facilities – the yarn break rate can be reduced by up to 30% by automating the wiping process. And the yarn break rate has a direct impact on the key production figures; to this end, a considerable reduction translates into pure profit for yarn manufacturers.

Can also be retrofitted to existing systems
The Oerlikon Barmag wiping robot can be retrofitted to numerous spinning plants. Suspended from a track system mounted on the ceiling, the system automatically and autonomously targets the individual positions in accordance with the scheduled wiping cycles. In addition to the scheduled wiping processes, there are also events that cannot be planned or that are not immediately visible. Depending on the degree of integration into Oerlikon Manmade Fibers Smart Factory solutions, the wiping robot is able to identify issues such as yarn breaks or parallel wiping processes and to independently offer solutions.

The wiping robot operates in a cross-line manner. Here, the wiping quality remains constant 24/7. The high wiping quality has a positive influence on both the stability of the overall process and on the yarn quality. The time saved between cleaning cycles is a further advantage: using the robots, the interval between two wiping processes can be extended by up to 25%. The considerable increase in the spinning process efficiency achieved by the wiping robot also has a positive impact on margins. For example, one customer deploying the wiping robot was able to reduce its production costs for the same yarn by more than 3%.

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.

Neumünster – Oerlikon Neumag has successfully commissioned three staple fiber bicomponent systems in China. With capacities of 50 tons per day each, the systems are being used to manufacture coresheath bicomponent fibers made from PP/PE or PET/PE at two long-standing Oerlikon Manmade Fibers customers. These fibers are used to make hygiene products.

Oerlikon Neumag staple fiber technology still in demand

Despite coronavirus-related restrictions, the three new systems were installed within three and five months, all without any problems. They have meanwhile been operating under stable production conditions with optimum fiber quality of the very highest standards for several weeks now.

Many years of experience in bi-component spinning

Oerlikon Neumag looks back on many years of experience in constructing bicomponent staple fiber systems. The first system for this fiber type was commissioned as far back as 1995. Oerlikon Neumag offers solutions for the most varied cross-sections, ranging from sheath/core’, ‘side-by-side’, ‘island in the sea’, ‘orange type’ as well as ‘trilobal’. The applications are diverse: from self-crimping fibers, bonding fibers, super-microfibers all the way through to hollow fibers.

The Oerlikon Neumag bicomponent technology is particularly characterized by the extremely robust spin packs that have no expensive wear parts, which considerably reduces the costs here. The reconditioning costs when cleaning the spin packs are kept to an absolute minimum. Add to this the separate temperature transfer option in the spinning beam for the two polymers. As a result, the quality and the viscosity of the polymers can be accurately adjusted in accordance with the respective process requirements.

• Schleswig-Holstein Minister President visits Neumünster, Germany

Since the outbreak of the coronavirus pandemic, the worldwide demand for protective masks and apparel has resulted in a record number of new orders in the high double-digit millions of euros at the Oerlikon Nonwoven business unit of the Swiss Oerlikon Group. From the manufacturing site in Neumünster, Germany, the high-tech meltblown systems – with their patented ecuTE+ nonwovens electro-charging technology – are meanwhile be exported all over the world. For the very first time, a contract has now been signed with a business in Australia. Today, Schleswig-Holstein’s Minister President Daniel Günther was won over on site by the technology of a ‘global player’. Rainer Straub, Head of Oerlikon Nonwoven, was thrilled, stating: “The machines and systems for manufacturing manmade fiber and nonwovens solutions from Neumünster enjoy an outstanding reputation throughout the world. It is especially in this crisis that the technology from Schleswig-Holstein has proven itself to be absolutely world-class.”

In addition to a tour of the meltblown system and its assembly and production facilities, the visit by Minister President Daniel Günther had one purpose above all: the dialog between politicians and business. Rainer Straub, Head of Oerlikon Nonwoven, and Matthias Pilz, Head of Oerlikon Neumag, jointly expressed their thanks for the support that Oerlikon has repeatedly had the fortune to experience over the past months and years in Schleswig-Holstein and looked to the future full of hope. “As a result of our additional investment at the site here in Neumünster – be this in our new technology center that will be completed by the end of this year or in our new logistics center that is already operating – we, as one of the region’s largest employers, are continuing to move forward, supported by a State Government that is also focusing on both promoting industry and business and on advancing an efficient training and educational system, as innovation is only possible with outstanding engineers”, stated Matthias Pilz. And Rainer Straub directed his appeal specifically at the Minister President: “Treat education and training as a priority. Ultimately, they will secure the future of Schleswig-Holstein as a center of excellence and manufacturing!”

Five-million-euro digitalization program

Daniel Günther, the incumbent Minister President of Schleswig-Holstein since 2017, immediately responded, making reference to one of the Federal State’s current training initiatives: “The State Government is supporting higher education institutions and students in the present coronavirus crisis. With a five-million-euro digitalization program, we are investing on the long-term digitalization of our higher education institutions. With this, we are overall creating a future for young people, particularly also for those who could very well go on to invent the next generation of manmade fiber systems.” And the Minister President was just as impressed by the willingness and readiness with which Oerlikon has been providing high-level support since the beginning of the COVID-19 pandemic to master the present challenges as he was with the company’s meltblown technology itself. Rainer Straub explained: “When, at the beginning of the pandemic in February, demand for protective face masks increased rapidly, we at Oerlikon Nonwoven responded immediately. We ramped up all the available production capacities here in Neumünster in order to quickly manufacture nonwovens for producing face masks using our laboratory systems. As a result, we have been able to make a small, regional contribution to covering demand. In parallel, we have pulled out all the stops in order to systematically further expand our skills as machine and system builders so as to cater to the initially expected, and now also continuing, global demand for meltblown systems as quickly as possible.”

Leading meltblown technology

The Oerlikon Nonwoven meltblown technology – with which nonwovens for protective masks can also be manufactured, among other things – is recognized by the market as being the technically most efficient method for producing highly-separating filter media made from plastic fibers. The capacities for respiratory masks available in Europe to date are predominantly manufactured on Oerlikon Nonwoven systems. “Ever more manufacturers in the most diverse countries are hoping to become independent of imports. Therefore, what we are experiencing in Germany is also happening in both industrialized and emerging countries throughout the world”, commented Rainer Straub. In addition to China, Turkey, the United Kingdom, South Korea, Austria and numerous countries in both North and South America, Australia and not least Germany will for the first time also be among the countries to which Oerlikon Nonwoven will be delivering machines and equipment before the end of 2021.

• Industrial yarn: Capacity expansion in the high-end sector

Remscheid – the Chinese industrial yarn manufacturer Zhejiang Kingsway High-Tech Fiber Co., Ltd. is expanding its production capacities by a further 40,000 tons per annum with 5 Oerlikon Barmag lines. Kingsway is already successfully manufacturing special high-quality yarns, exclusively deploying Oerlikon Barmag industrial yarn systems.

The 21 new spinning positions will be used to manufacture a broad product range: in addition to super-low-shrinkage (SLS) and high-tenacity (HT) yarn, the business also plans to produce automotive yarns for seat belts and airbags. This flexibility is made possible as a result of the Oerlikon Barmag systems’ configuration. The new systems are expected to commence manufacturing next year.

Industrial yarns for greater safety

As a quality-conscious industrial yarn producer, Kingsway has been manufacturing its sophisticated, high-end yarns on Oerlikon Barmag filament yarn systems since 2015. Alex Yang Yu Long, CEO of Kingsway, is proud of relying on engineering artistry from Remscheid: “As expected, the yarns are first-class in terms of quality. Our products are used in safety equipment, sometimes in situations where lives depend on them. Therefore, there can be no compromises. To this end, we select our partners with the utmost care."
