From the Sector

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.

In pandemic year 2020 circular knitting machine manufacturer Mayer & Cie. (MCT) has further improved its leading position in Turkey. So the country continues to be one of the company’s strongest and most consistent sales markets. Even in difficult years, the manufacturer and its longstanding Turkish representative Mayer Mümessillik have achieved positive results. The reasons for this year’s success, as Mayer & Cie. sees it, are the transfer of production to locations close to Europe, Turkey’s state-of-theart machinery and the increase in demand for comfortable clothing that is suitable as home office wear.

Turkish market is a growth market despite corona setback
“Compared to 2019, we anticipate a growth in the Turkish market even though the corona situation was a serious setback in the second quarter of 2020,” says Stefan Bühler, Mayer & Cie.’s regional sales manager for Turkey.

Mayer & Cie. got off to a strong start on the Bosporus in the first quarter of 2020 with additional positive effects until mid-March. This was due to a desire for production locations close to Europe. In the second quarter, during the lockdown, demand largely ground to a halt. Government measures helped to cushion the downturn. Says Ahmet M. Öğretmen, general manager of MCT’s Turkish sales partner Mayer Mümessillik: “In the second quarter, GDP was down by about 10 percent, so we got off lightly.”

Since July 2020, orders for Mayer & Cie. circular knitting machines have bounced back again. Ahmet M. Öğretmen sees an interplay of reasons for this recovery. The main reason, he says, is the low exchange rate of the Turkish lira, which has boosted exports of ready-made textiles. The Turkish daily Hürriyet reports, with reference to the Turkish state news agency, 11 percent year-on-year growth in August 2020. The most important export markets, the newspaper says, are Germany, the UK and Spain. Between them, they account for around half of exports totalling € 1.27 billion.* “This demand must be fulfilled,” Öğretmen says. “That leads to investment in machinery by manufacturers.”

Relanit is synonymous with single jersey
The machines of choice for Turkish knitwear manufacturers are regularly Mayer & Cie. machines. The long-established German firm’s share of the Turkish market is substantially higher than in other markets. The manufacturer’s position is particularly strong in the market for plain single jersey fabrics, with the Relanit 3.2 HS being the machine of choice. It achieves an extraordinarily high level of productivity, especially in processing elastomer yarns. It also handles a wide range of yarns reliably.

“Interlock is Mayer & Cie.”
Mayer & Cie. is one of the leader in the second major circular knitting discipline, rib and interlock fabrics. The machines used for double jersey fabrics are the OV 3.2 QCe, the D4 2.2 II and the D4 3.2 II. The OV 3.2 QCe knits interlock, 8-lock structures, spacers and fine gauge with 3.2 systems. The D4 2.2 II is another stalwart for rib, 8-lock and interlock. The 8-lock D4 3.2 II is the machine of choice for firms that want to manufacture structures such as Piqué, Punto di Roma or Thermal in addition to interlock.

The MBF 3.2 is another top seller in Turkey. A three-thread fleece machine, it knits fabrics for sportsand leisurewear such as hoodies and is very much in keeping with the trend in home office year 2020. “Comfortable clothing is circular knitted,” says Ahmet M. Öğretmen, “and we benefit from that of course.”

One of the world’s most state-of-the-art machine parks are in Turkey
Another advantage is the modernity of the Turkish machine park, which is doubly attractive in view of Turkey’s weak currency. Says Mayer Mümessillik general manager Öğretmen: “In the past 10 to 20 years there has been very heavy investment in high-quality machines. As a consequence we have the world’s youngest and most up-to-date production facilities.” Combined with geographical proximity to the main export markets in Europe that should prove a growth driver in the years ahead – and keep demand for Mayer & Cie. machines brisk and high.

• Carbon fibers combined with injection molding replace conventional steel construction
• SGL Carbon supplies innovative carbon fiber profiles
• Serial use in a future high-volume model of BMW Group
• Construction method offers great potential for use in other automotive projects

Already in August, SGL Carbon received a multi-year order from Koller Kunststofftechnik GmbH for the production of novel carbon fiber profiles for serial use in windshields for a future high-volume model of BMW Group.

The profiles are particularly flexible fiber tows, pre-impregnated with thermoplastic resin in various dimensions. They will be compiled by SGL Carbon on the basis of its own 50k carbon fiber at its site in Innkreis, Austria, and subsequently processed by the injection molding experts at Koller to form a skeletal plastic component. The composite component will replace the previous steel-based windshield. Production of the carbon fiber profiles will start in the remainder of 2020 and will then be ramped up gradually over the next few years for the BMW Group model launch.

In the vehicle, the windshield is a connecting element between the roof frames and thus has an important stabilizing function. The carbon fiber profiles add the required stiffness and crash safety to the component. At the same time, they help to significantly reduce the weight of the roof and thus also support the driving dynamics. The injection molding process also enables particularly complex and material-efficient structures. In the BMW Group model, this innovative component concept will cut weight by 40 percent compared to conventional steel designs of the component while creating important space for cable ducts and sensors.

The production of the carbon fiber profiles themselves is also particularly geared to material and process efficiency in large-scale production. The profiles consist of several smaller fiber strands, the so-called rods, and are manufactured using the modern continuous pultrusion process. During product and process development it was one key objective to ensure that material loss during production is almost completely avoided.

"At SGL Carbon, we have been working on the development of thermoplastic carbon fiber profiles for use in injection molding for some time already. This development work is now beginning to pay off. Due to the many advantages and competitive costs, we see a great potential for the technology to be used in other automotive projects too," explains Sebastian Grasser, Head of the Automotive Segment in the Business Unit Composites - Fibers & Materials at SGL Carbon.

"Innovative lightweight construction with hybrid designs has developed into a strategically conclusive concept for Koller Group's OEM customers," confirms Max Koller, CEO of Koller Group. "SGL Carbon's high level of material expertise, combined with the process know-how of KOLLER Kunststofftechnik and KOLLER Formenbau, create the basis for a promising future in innovative lightweight construction technologies. With this order, the BMW Group has confirmed its confidence in the successful cooperation between SGL and Koller; we are particularly pleased about this", said Max Koller.
 
The Koller Group is a globally operating technology company with plants in Europe and China, as well as NAFTA. The Koller Group develops and manufactures lightweight construction, tools and serial components, primarily for the automotive industry.

At first glance, rowing boats, the Airbus 380, safety equipment and stadium roofing have very little on common. They receive their specific properties as a result of the use of special fibers, among other things: aramid fibers and carbon fibers are processed into special yarns that are frequently deployed as compound materials. These fibers are growing in demand as the world seeks to reduce its reliance on fossil fuels; new solutions are required to reduce weight and replace heavy metallic parts.

Aramid fibers are produced in a highly-chemical process that is extremely aggressive; the acrylic precursor used to manufacture carbon fibers is a different process, but again no less difficult. In these sophisticated processes, the gear metering pumps are not only responsible for the high-precision control of the melt transport; durability, resistance within aggressive environments and cost efficiency also play decisive roles.

Special materials for special tasks
The process, the expected pump lifespan and the maintenance frequency are the decisive factors for choosing the materials from which the pumps and their components are manufactured. For optimum results, Oerlikon Barmag offers solutions that intelligently combine the various materials and the latest technologies. Whether in the case of surfaces with ceramic coatings, gears and shafts featuring DLC coatings, pumps made from cobalt alloys (StelliteTM) or robust and durable Oerlikon Barmag hybrid constructions comprising zirconium oxide ceramic and duplex stainless steel – the high-precision ZP- and GM-series pumps are design-optimized depending on the intended use. Various seal systems and customized drive concepts round off the pump program.

• Royal DSM, a global science-based company in Nutrition, Health and Sustainable Living, today announced that, for the first time, Dyneema® Composite Fabrics are used by Moncler in the Fall/Winter 2020 Grenoble collection, which fuses form and function into high performance skiwear.

Moncler Grenoble is born of a passion for research and implements cutting-edge technology to push the limits of its potential. The design team identified Dyneema® as an innovative fabric it could use to push the level of its performance to the next peak, incorporating the material into the new collection as a departure from the conventional use of cotton and polyester.

Sandro Mandrino, the Head of Design for Moncler Grenoble, was the first designer of the luxury fashion brand to incorporate Dyneema® into one of his creations through the Moncler Genius project. The Moncler Genius project advocates radical co-creation where multiple designers create their own signature collections in collaboration with the house. Together, these collections translate into one vision of the future and, as one of the nine designers, Mandrino’s interpretation of the future of fashion features Dyneema® Composite Fabric.

Using variations of the fabric in both white and black allowed Mandrino to bring his vision to life by merging skiwear, space suits and technology all in one. “ 3 Moncler Grenoble is first and foremost about performance,” states Mandrino, who integrated constructive solutions with fabric technology to develop a line that was meant to perform both on and off the ski slopes.

Dyneema®, the world’s strongest and lightest fiber, is 15 times stronger than steel yet light enough to float on water. The unmatched performance and protection of products made with Dyneema® have made it the material of choice in critical applications where failure is not an option for more than 30 years. In fabric form, Dyneema® is available in composites, denim, knits, wovens and hybrids for composite reinforcements. And because Dyneema® fabrics are made using Dyneema® fiber, they intrinsically provide high strength, low weight, waterproof and breathable properties – allowing designers to fuse the technical performance of ultra-light products with aesthetic design that doesn’t sacrifice strength or durability.

The Moncler team used the Grenoble collection as an opportunity to experiment and further understand the nature and behavior of Dyneema® fabrics, while simultaneously incorporating material performance with practical design. “Future collections will focus on expanding to new designs and fabric options in collaboration with DSM,” adds Mandrino.

“We are very excited to be working with the Moncler team to launch a collection of wonderful garments that allow people to explore the outdoors more safely and for longer periods of time,” states Marcio Manique, Global Business Director, Consumer & Professional Protection, DSM Protective Materials. “We look forward to further supporting Moncler as they develop innovative, high-tech garments that are also sustainably sourced through the introduction of bio-based Dyneema® fabrics.”

In line with DSM’s commitment to protect people and the environment they live in, the world’s first-ever bio-based ultra-high molecular weight polyethylene fiber was introduced in May 2020. Bio-based Dyneema® boasts the same exact performance as conventional Dyneema® with a carbon footprint that is 90 percent lower than generic HMPE. DSM and Moncler’s continued partnership will not only provide high performance, light weight garments for outdoor enthusiasts but also environmentally sustainable alternatives that contribute to a more circular economy.

• Composite textiles for modern mobility
• Extremely lightweight, high tensile components by vombaur

In the snow, on a plane, in an electric vehicle or on a bicycle: no matter where and how we are on the road – composite textiles by vombaur ensure that we make good progress. With materials that are both extremely light and extremely reliable.

Lightweight components for modern mobility
Modern mobility relies on high-tech lightweight components Narrow textiles by vombaur are woven from high-performance fibres. On looms that are specially made for particularly demanding composite textiles: the textile company uses special machines to produce high-tech woven tapes with closed selvedges and elasticated UD tubulars that retain their 0° orientation over the entire length of the component – regardless of the diameter. Since they do not exhibit undesired break points caused by seams or welding, they not only have a particularly high bursting strength, they are also extremely reliable and durable.

Challenging applications
"From snowboards to aerospace – the applications for our composite textiles are demanding; the mechanical, chemical and thermal requirements are extreme," explains COO Christoph Schliefer. "As a development partner, we at vombaur are therefore often involved in product development at an early stage. We specify our woven tapes and tubulars individually for each project to suit the specific task at hand."

High quality raw materials, wide variety of geometries
The variety of shapes is virtually unlimited. vombaur manufactures 3D fabrics for composites in individual special shapes from carbon, aramid, glass or hybrids. Curves, edges, tubulars, spiral fabrics – the shape of the 3D fabrics, like the material itself, depends entirely on the task at hand. Powder or non-woven coatings create additional important properties.

Pioneering tech tex
"Developments in the field of modern mobility are happening at a rapid pace," emphasizes Schliefer. "With our composite textiles for extremely lightweight and high tenacity components, we at vombaur are also pushing these developments forward."

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.

•   Mimaki Tiger-1800B MkII Printers for Faster, High-Quality Textile Printing

Amsterdam - Mimaki Europe, a leading manufacturer of inkjet printers and cutting systems, announces today that Pakistani textile company, Moti Fabrics (Pvt) Ltd., is leveraging multiple Mimaki Tiger industrial textile printing units to take its business to the next level. As a result of on the outstanding performance and process optimisation delivered by the Mimaki digital printing equipment, the company has been able to adapt to changes in the textile industry and is now projected to reinforce its market position and expand its capabilities in high-quality textile production.

Headquartered in Faisalabad, Punjab province – the second largest textile hub in Pakistan –, Moti Fabrics (Pvt) Ltd. mainly serves the high fashion industry and uses its cutting-edge technology to print about 100,000 metres daily. Faced with recent challenges in the global textile market, management at Moti Fabrics (Pvt) Ltd. embarked on innovating the company’s business model, shifting from conventional to digital printing.

The Tiger-1800B MkII is Mimaki’s flagship industrial volume textile printer, available either in dye sublimation configuration for transfer printing or with reactive ink for direct-to-textile printing. Of the three Mimaki Tiger-1800B MkII solutions operating at Moti Fabrics (Pvt) Ltd., two are equipped with reactive inks, enabling the company to directly print onto natural fibres such as cotton and linen, as well as onto manufactured cellulose fibres, including rayon and nylon. The third Mimaki Tiger-1800B MkII features sublimation inks serves the ever-growing printed polyester market, allowing the company to strategically diversify its product portfolio.

“There are several features of the Tiger-1800B MkII that benefit our production and our business at large. The MAPS (Mimaki Advanced Pass System), just to name one, prevents banding and colour-shifting to deliver a higher standard of quality, while the NRS (Nozzle Recovery System) provides uninterrupted production, minimising downtime and ensuring superior results. The sticky belt system together with the large-size ink tanks (with a capacity of 10kg) and the high-performance software RIP TxLink3 are some of the other features that make these printers efficient, user-friendly and reliable,” says Asif.

Asif concludes, “Looking at the future, our aim is to set up a print department featuring only Mimaki’s technologies. We are already considering the next steps to make this possible, knowing that we can count on the support of Signtrade, Mimaki’s dealer in the region and our trustworthy partner.”

Moti Fabrics (Pvt) Ltd. was founded in 1992 by Muhammad Asif’s father Haji Muhammad Yousaf and his partner Haji Rasheed Ahmad. Established as a dyeing company, Moti Fabrics (Pvt) Ltd. was able to gradually diversify the business over the years to become an advanced textile printing specialist. Today, the company is an established provider to the high fashion industry in Pakistan and on an international level.

“The story of Moti Fabrics is incredibly inspiring. Belonging to a region with such rooted textile printing heritage, the company has been able to embrace a new, challenging business model in order to stay at pace with the changing demand from the textile industry and has succeeded,” comments Ronald van den Broek, General Sales Manager at Mimaki Europe. “Customers like Moti Fabrics make us proud as they demonstrate how our advanced Mimaki Tiger industrial textile series can be the enabling technology for those textile companies planning the shift from conventional to digital printing.”

Technical textiles fulfil many functions: they hold, they lift, they fixate, they stretch – and they tension. In this function narrow textiles fulfil an important task in product development. And they offer significant advantages over metal or plastic tensioning devices such as springs, clamps or cable ties.

Properties
Textiles are light: a property that plays a central role in modern mobility. Textiles are flexible: from extremely high to extremely low elasticity: the force-elongation behaviour of elasticated narrow textiles can be precisely defined. Depending on the tensioning task to be performed. Textiles tension in tight packaging spaces: elastics can also be used where space is too tight for springs and clasps. Textiles are energy efficient: lightweight, with high tensioning force. Textiles are easy to handle: replace a connector spontaneously and without tools, quickly change the length or roll up and store a supply. And textiles are sustainable: natural fibres and rubber are natural and ecologically degradable raw materials; synthetic fibres can be completely produced from recycled materials.

Applications
Development teams in numerous industries leverage these properties for their products. For example, for flexible machine parts in mechanical engineering, for switch contacts in electrical engineering, for oscillation-capable locking systems in the construction industry, for noise- and vibration-free seating systems in the automotive sector or for grip rings in the toys industry.

Tasks
Particularly en vogue today, when we are spending more time than usual in our own homes: applications for narrow textiles in the furniture industry. They go far beyond the area of legacy home textiles: as tensioning elements in armchairs, sofas and chairs, as hinge solutions in cupboards, as fixation elements in extendable or folding tables. Narrow textiles are used for gripping tasks almost everywhere in the living room.

"JUMBO-Textil specialises in precisely implementing the individual requirements for defined force-elongation values of elasticated narrow textiles: we adapt the technical properties of our products precisely to the specific task and the respective raw materials," explains Werner Thiex, Sales Director Automotive. "Precise technical specification plus sustainable raw materials – this is a crucial combination in the 21st century".

Anker, Devan and Shark Solutions teamed up to create the world’s first flame retardant aviation carpet using a recycled binder. Inspired by the knowledge and the needs of the aviation market, Anker motivated to achieve this new goal together. The PVB binder reuses laminated glass, from windshields and architectural/building glass, that otherwise would go to landfill.

German carpet manufacturer Anker is the first company to offer flame retardant carpets for aviation that are made with a recycled binder. In the search for a more sustainable binder, Anker discovered the PVB from Shark Solutions, a Danish cleantech company focused on giving a new life to post-consumer PVB. Properties of the aviation carpet with PVB as binder are the same as those of traditional non-sustainable carpets. The market has been looking for this type of solutions for a long time and market introduction has already started. Anker will introduce well known and special developed styles of aviation carpets with PVB and plan to take out traditional non-sustainable aviation carpets stepwise as soon as possible.

Shark’s PVB reuses laminated glass, from windshields and architectural/building glass, that otherwise would go to landfill. The non-toxic binder (no chlorine or phthalates) is fully recyclable and thus lives up to the future standards of the industry.

Textile innovator Devan Chemicals, known for its tailor-made flame retardant solutions, was called in to develop the flame retardant back coating, which is compliant with the Airbus and Boeing safety standards. “Based on many years of experience and competences in customer related developments, improving recycling rates is getting more and more important”, says Dirk Vanpachtenbeke, R&D manager Flame Retardants at Devan. “We are very proud that, together with Anker and Shark Solutions, we can contribute to this rising demand for products that meet the standards of a circular economy solution.”

In other news, Anker and Devan are already working on a new project, which includes Devan’s antimicrobial/viral-reducing technology. Recently, Devan published test results on the activity of their technology (BI-OME®) against SARS-CoV-2 and other viruses. According to independent testing, BI-OME is proven to achieve 99% and higher virus reduction, including of SARS-COV-2, on samples before washing and retains 98.5% even after 25 wash cycles. This technology has been recognized with the 2020 European Technology Innovation Leadership Award by Frost & Sullivan.
