From the Sector

Cooperation and business development with AMAC
As of November 1st, 2020, AMAC is pleased to announce its cooperation with company FibreCoat for the market introduction of their products and global business development. FibreCoat is a young, award-winning start-up and spin-off of the RWTH Aachen University in Germany and develops multi-filament coated yarns, fabrics and composites based on glass or basalt fibres.

Dr. Michael Effing, CEO AMAC GmbH: „FibreCoat is a very promising newcomer in the electro-magnetic shielding and composites industry and their innovations are very cost-efficient for new technologies such as e-mobility or telecommunications. I am very pleased to introduce them to relevant key players in the industry and accompany them in their growth strategy.“

Product Launch
FibreCoat develops metal-coated fibres like bi-component multi-filament yarns with basalt core and aluminum coating which can be used for EMI-shielding and heat sinks in battery casings, electric diverters in filters, reinforcement of cast aluminum parts o ras conductive yarns in smart textiles.

FibreCoat launches ALUCOAT™, an aluminum-coated glass or basalt fibre which is suitable as electro-magnetic shielding material in automotive applications such as radar, antennas or for autonomous driving as well as for mobile phones and applications in buildings. Due to its extraordinary thermal conductivity and better heat transfer compared to traditional composite material, it can be used for the manufacturing of automotive battery trays or industrial applications such as fine particulate air filters.

ALUCOAT™ is available as of January 1st 2021 as a yarn, fabric or non-woven with a wide range of possible titers and areal weight. The material will offer an electrical conductivity of 100 Ωm and a working temperature of at least 400 °C. Furthermore, it can be used for the shielding of low to high frequencies with an effectiveness of 80 to 120 dB.

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 Cetex Institut gGmbH, the thermoPre ENGINEERING GmbH and The FilamentFactory GmbH cooperate in the development, production and marketing of novel hybrid materials. The cooperation agreement signed on October 2, 2020 in Chemnitz takes the collaboration to a new level. "We are pleased to be able to supply the hybrid rovings to the end user not only in an application-specific manner, but also to offer the engineering for subsequent component applications, including the prototyping of the FRP components," says Sebastian Nendel, Managing Director of Cetex.

Patented process for the production of hybrid rovings
In the last 3 years the Cetex Institute has developed a plant technology for the production of hybrid rovings. By means of the patented process, different material combinations can be produced according to customer specifications. Material combinations of reinforcing fibers (glass, basalt, carbon, aramid or high-strength polymer fibers) can be combined with matrix fibers (PP, PET, PA, PPS, PEEK), but also special combinations of different reinforcing fibers or the combination of reinforcing fibers with metal fibers. Advantages of the new hybrid roving are the torsion-free and completely stretched fiber layer and the associated optimal utilization of the properties of the reinforcing fibers, as well as a very good homogeneity, whereby excellent processing can be achieved in later process steps.

Series production as next step
The next goal is clearly defined: Under the agreement, the process is to be jointly developed further by the project partners and transferred to series production. These joint activities form the basis for many years of intensive cooperation in this new field.

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.

• 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."

Long-term project business in China remains stable 

Oerlikon has received new large orders for manmade fibers production solutions from three of the world’s leading manmade fibers manufacturers. All three companies are based in China and have been key customers of Oerlikon for many years. The orders are for Oerlikon Barmag’s world-leading filament-spinning technology for the highly efficient production of polyester fibers. The three projects have a total value of more than CHF 600 million (EUR 565 million). A very small proportion of these projects will be recognized in Oerlikon Group’s order intake in 2020, and the majority will be accounted for in 2021 and 2022. On-site delivery and installation of these systems are planned for the period from 2021 to early 2023.

The systems business in China remains largely unchanged despite the short-term interruption caused by the coronavirus epidemic following the Chinese New Year celebrations. Long-term project planning for major customers in the manmade fibers industry has resulted in new major orders being placed with Oerlikon Barmag. One of the three new orders, valued at more than CHF300million (EUR282million), is the largest order ever received by Oerlikon Barmag, based in Remscheid, Germany.

The comprehensive manmade fibers technology solutions by Oerlikon are used along the entire value chain in polyester yarn manufacturing and contain cutting-edge automation and digitalization technologies. Oerlikon’s innovative technologies will enable the three Chinese companies to increase their production capacities for polyester yarn and to remain competitive. Oerlikon Barmag will provide the entire system for WINGS POY and WINGS FDY, as well as the texturing machines from the eFK product family in phases over a period of slightly over two years.

The Oerlikon Nonwoven experts will be presenting efficient solutions and comprehensive technology know-how for challenging filtration tasks to an international trade audience at the FiltXPO 2020 in Chicago, USA (Stand # 420), taking place between February 26 and 28.

Meltblown technology is one of the most efficient methods for producing very fine and highly-separating filter media made from manmade fibers. New, unique and highly-sophisticated filter media are easy to manufacture thanks to Oerlikon Nonwoven’s optimized meltblown technology. This process is characterized by its constant melt pressure distribution and consistent dwell time across the entire width of the spinning beam, Furthermore, the novel guidance and distribution of the process air outside the coathanger distributor offered by the Oerlikon Nonwoven technology prevents so-called hotspots, which overall ensures particularly homogeneous nonwoven properties and basis weights even in the case of delicate raw materials.

The Oerlikon Nonwoven charging unit stands out against other concepts currently available on the market. Users can freely choose from a large number of variation possibilities and set the optimum charging method depending on the filter application, allowing the Oerlikon Nonwoven charging unit to also be used for the manufacture of EPA- and HEPA-class filter media.

The new forming section ensures improved nonwoven formation evenness across the entire width, even in the case of high spinning speeds, special polymers and polymer combinations. In addition to this, the newly-designed system also ensures that nonwovens only require minimal edge trimming at the end of the production process. The newly-developed mixedfiber technology enables the combining of various filament cross-sections and polymers, in order to set ideal filtering and pleating performances, for example.

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

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

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

PERLON® - The Filament Company presenting will be showcasing PearlTech®, their latest product brand at Techtextil in Frankfurt from 14th – 17th May. PearlTech® is a monofilament which has special particles incorporated into it. The size and shape of the particles is irregular and the material is unrelated to the base polymer.

PearlTech® is currently available in a PET based variant as well as in PA. The particles are added into the polymer melt and evenly distributed over the whole cross-section. These newly acquired properties remain intact throughout the lifetime of the monofilament. The particles incorporated into the polymer matrix protrude slightly from the monofilament surface, giving PearlTech® an interesting optical appearance and a structured surface finish.

PearlTech® provides improved stability against wear, reduces machine power consumption whilst reducing the build-up of dirt on the end product. This is in comparison to standard polymers. The particles have no negative effect on hydrolysis resistance and furthermore offer the possibility to avoid the use of fluoropolymers.

New products for photopolymer and laser sinter printing methods from BASF 3D Printing Solutions GmbH (B3DPS) are on show from November 13 to 16 at Stand F20 in Hall 3.1 at this year’s formnext fair in Frankfurt. The BASF subsidiary is also announcing several new partnerships for the development and distribution of groundbreaking 3D printing solutions and products.

B3DPS has entered into a strategic partnership with the US company Origin, San Francisco, California for the further development of photopolymer printing processes. “Within the framework of an open business model, we are combining BASF’s material know-how with Origin’s expertise in printer software programming and the manufacture of the corresponding hardware,” explained Volker Hammes, Managing Director BASF 3D Printing Solutions GmbH. The collaboration has already shown the first signs of success. Origin has developed a new printing method where BASF’s new Ultracur3D photopolymers can be processed particularly well. The technology offers an optimal combination of a good surface finish and high mechanical stability, while also allowing for high material throughput.

B3DPS is working together with Photocentric, a manufacturer of 3D printers and their corresponding software and materials, on the development of new photopolymers and large-format photopolymer printers for mass production of functional components. Based in Peterborough, UK and Phoenix, USA, Photocentric has developed and optimized the use of LCD screens as image generators for its own printing systems. The two partners plan to offer the industry 3D printing solutions that replace parts of traditional manufacturing processes such as injection molding for small series, as well as enabling the production of large components.

The objective of the cooperation with Xunshi Technology, a Chinese printer manufacturer headquartered in Shaoxing, and operates in USA under the name Sprintray, will be opening new fields of application in 3D printing for the Ultracur3D product range of B3DPS.

Ultracur3D specialties for photopolymer printing processes
B3DPS has grouped well-established and new photopolymers designed for the respective 3D printing processes under the brand name Ultracur3D. BASF has developed unique raw materials for its new products that enable special part properties.
“Our Ultracur3D portfolio enables us to offer customers various UV-curable materials for 3D printing that provide far better mechanical properties and higher long-term stability than most available materials,” explained András Marton, Senior Business Development Manager at B3DPS. He added: “These materials have been developed for functional components that are subject to high stress.”

Expansion of distribution network for filaments
Innofil3D, a subsidiary of B3DPS, is entering into a partnership with Jet-Mate Technology, based in Tjanjin, China, for the distribution of plastic filaments in China. In parallel, a distribution agreement has been concluded with M. Holland in Northbrook, USA for the distribution of filaments in USA. “Since the USA is the largest market for filaments, we intend to strengthen our activities there,” said Jeroen Wiggers, Business Director 3DP Solutions for Additive Extrusion at B3DPS, adding: “Asia is another important market for us. We will be developing further distribution channels there and putting our Ultrafuse filaments on the Asian market in 2019.”

BASF’s portfolio of filaments for 3D printing are comprised of two categories; the well-established Innofil3D filaments based on generic polymers for conventional applications and polymer-based Ultrafuse filaments for advanced formulations used in demanding technical applications. One of the broadest filament selections on the market, this portfolio covers customer requirements ranging from prototype to industrial-scale production.

SLS: new 3D printing material with fire protection classification
New flame-resistant Ultrasint Polyamide PA6 Black FR meets UL94 V2 fire protection standards and is a new material class for use in selective laser sintering (SLS) processes, distinguished by high stiffness and thermal stability. In cooperation with one of the global leaders of public transportation vehicles, B3DPS has developed new components that meet vehicle fire protection requirements. “Together with our partner, we are currently producing prototypes, spare parts, and small series components, and are working to further improve flame resistance to meet additional certification specifications,” explained Hammes.
BASF introduced Ultrasint Grey PA6 LM X085 at AMUG this spring and now is followed by another product on show at formnext. Ultrasint PA6 Black LM X085 is based on polyamide 6, and can be processed at 175-185 degrees Celsius therefore making it suitable for most current SLS machines.

B3DPS adds polypropylene to its 3D printing portfolio
Through the acquisition of Advanc3D Materials GmbH in July 2018, B3DPS has expanded its range with numerous materials for use on laser sinter machines, including polyamide Adsint PA12, Adsint PA11, Adsint PA11CF and Adsint TPU flex 90.
Ultrasint PP is a special highlight. This polypropylene-based product exhibits outstanding mechanical properties and is frequently used in standard industrial production as it offers a good balance between price and performance. Ultrasint PP is distinguished by excellent plasticity, low moisture uptake, and resistance to liquids and gases. Prototypes and small batches can now be produced from the same material as used for traditional serial production. Post treatments such as thermoforming, sealing, and dyeing can be performed after printing.
