From the Sector

The future of e-mobility will be determined in particular by safe battery enclosures. As batteries for electric vehicles become more performant, higher volumetric energy density plays a crucial role. If more energy is to be stored in less installation space, new material and design solutions are required. The development of suitable enclosures made of safe and highly robust lightweight materials is also required. This is a case for the Aachen Centre for Integrative Lightweight Production (AZL). A project on cell-to-pack battery enclosures for battery-electric vehicles, which has been eagerly awaited in the industry, will start in October this year there.

The design of battery housings is crucial for safety, capacity, performance, and economics. The Cell-to-Pack project, which is starting now, will focus on developing concepts for structural components and for producing them based on a variety of materials and design approaches. The concepts will be compared in terms of performance, weight and production costs, creating new know-how for OEMs, producers and their suppliers throughout the battery vehicle value chain. Companies are now invited to participate in this new cross-industry project to develop battery enclosure concepts for the promising and trend-setting cell-to-pack technology.

The basis for the project is the lightweight engineering expertise of the AZL experts, which they have already demonstrated in previous projects for multi-material solutions for module-based battery housings. Together with 46 industry partners, including Audi, Asahi Kasei, Covestro, DSM, EconCore, Faurecia, Hutchinson, Johns Manville, Magna, Marelli and Teijin, 20 different multi-material concepts were optimized in terms of weight and cost and compared with a reference component made from aluminum. All production steps were modelled in detail to obtain reliable cost estimates for each variant. Result: depending on the concept, 20% weight or 36% cost savings potential could be identified by using multi-material composites compared to the established aluminum reference.

It is expected that the design concept of battery enclosures will develop in the direction of a more efficient layout. In this case, the cells are no longer combined in modules in additional production steps, but are integrated directly into the battery housing. The elimination of battery modules and the improved, weight-saving use of space will allow for higher packing density, reduced overall height and cost saving. In addition, various levels of structural integration of the battery housing into the body structure are expected. These new designs bring specific challenges, including ensuring protection of the battery cells from external damage and fire protection. In addition, different recyclability and repair requirements may significantly impact future designs. How the different material and structural options for future generations of battery enclosures for the cell-to-pack technology might look like and how they compare in terms of cost and environmental impact will be investigated in the new AZL project. In addition to the material and production concepts from the concept study for module-based battery enclosures, results from a currently ongoing benchmarking of different materials for the impact protection plate and a new method for determining mechanical properties during a fire test will also be incorporated.

The project will start on October 27, 2022 with a kick-off meeting of the consortium, interested companies can still apply for participation until then.

• Sales increase of 10.7% to €549.8 million in the first half of 2022
• EBITDApre improves by 22.6%, higher than the increase in sales, to €87.9 million
• Positive business development, price increases and strict cost management led to forecast increase on June 7, 2022

Despite uncertain general conditions in the first six months 2022, SGL Carbon's business model is proving its resilience. After €270.9 million in Q1 2022, SGL Carbon was able to increase sales to €278.9 million in Q2. Accordingly, sales for the first half of 2022 amount to €549.8 million, which corresponds to a sales plus of €53.1 million or 10.7% compared to the same period of the previous year.

The increase in sales was driven in particular by customers in the semiconductor industry and growth in the industrial applications market segment. Demand from the automotive and chemical industries was also encouraging.

EBITDApre, as one of the Group's key performance indicators, improved by €16.2 million (+22.6%) to €87.9 million (H1 2021: €71.7 million). Consequently, the EBITDApre margin increased from 14.4% to 16.0%. In addition to the higher utilization of production capacities due to higher sales, the improvement in earnings was also driven by the largely successful passing-on of higher raw material and energy costs to customers as well as savings from the transformation program.

EBITDApre does not include positive one-off effects and non-recurring items totaling €10.6 million (H1 2021: minus €5.2 million). As a result, EBIT in H1 2022 increased significantly from €38.3 million to €69.6 million. Taking into account the financial result of minus €16.6 million (H1 2021: minus €14.0 million), consolidated net income for the first six months of the current fiscal year amounted to €48.8 million, compared to €17.9 million in the prior-year period.

Business Units
With an increase in sales of €22.2 million (+10.0%) to €243.4 million, the Graphite Solutions (GS) business unit made a major contribution to SGL Carbon’s sales growth. In particular, continued high demand from customers in the semiconductor sector, which represents approximately one third of the segment's sales, led to the positive business development in GS. As a result of the predominantly high-margin business, EBITDApre at GS improved by 22.7% to €54.0 million.

The Process Technology (PT) business unit benefited from the good order situation in the chemical industry in H1 2022 and consequently increased sales to €49.2 million (H1 2021: € 40.8 million). EBITDApre also improved from €0.1 million in the prior year’s first half to €4.1 million in H1 2022.

The Carbon Fibers (CF) business unit benefited in the 1st half 2022 from final deliveries to a major automotive manufacturer whose contract expired as scheduled on June 30, 2022. Segment sales increased by 5.8% year-on-year to €176.0 million. In contrast, EBITDApre at CF decreased by €4.2 million to €28.2 million despite the good order situation and successful price increases. It should be noted that CF was impacted by a special effect from energy derivatives for price hedging in the amount of €9.2 million in the first quarter of 2022.

With an increase in sales of 15.6% to €69.6 million, the Composite Solutions (CS) business unit continued its upward trend. The specialist for customized component solutions for the automotive industry improved its EBITDApre from €5.7 million in the first half of 2021 to the current €9.7 million, based in particular on price and volume effects.

Balance sheet figures
Working capital rose by 11.7% to €381.1 million as of June 30, 2022. This was mainly due to higher inventories (€ +73.9 million) and an offsetting increase in trade payables (€ +29.0 million). A targeted build-up of inventories in critical raw materials due to disruptions in transport routes and the recent Covid lockdown in Shanghai were some of the reasons for the higher inventory levels.

SGL Carbon's net financial debt slightly increased by €6.6 million to €212.9 million as of June 30, 2022 (Dec. 31, 2021: €206.3 million), which was due to a lower free cash flow of €7.5 million for H1 2022 (H1 2021: €56.6 million).

Guidance increase
On June 7, 2022, SGL Carbon raised its sales and earnings guidance for fiscal year 2022. The company now expects sales of €1.1 billion (previously: around €1.0 billion) and EBITDApre of €130 - 150 million (previously: €110 - 130 million). Based on the pleasing business development, realized price increases, a stringent cost management, and taking into account the currently known risks, SGL’s management expects to achieve the earnings forecast for 2022 at the upper end of the stated range.

The adidas TERREX HS¹ is one of the first knitted products to be made in part with Spinnova technology. At least 30% of the fabric in this mid-layer hiking hoodie comes from wood-based SPINNOVA® fibres (other fibres)* and 70% from cotton (organic).

Adidas is committed to helping End Plastic Waste via a three-loop strategy that consists of using recycled materials, materials that can be made to be remade and in the case of Made with Nature, products created in part with natural ingredients, such as the adidas TERREX HS¹.  

The first product to emerge from this partnership, the adidas TERREX HS¹ mid-layer is a piece of multi-functional gear that works on the trails and then rolls up into its hood for easy storage or to create a pillow on longer adventures. It was designed using UNITEFIT – an all-gender fit system created with a spectrum of sizes, genders, and forms in mind.

Made in part with Spinnova technology , a minimum of 30% of the fabric in the adidas TERREX HS¹ comes from wood-based SPINNOVA® fibres (other fibres)* that are made by grinding wood pulp with water into a paste and then spun into a textile fibre.

The product also works with the material’s natural color. Since no dyeing or bleaching is applied, in turn this uses less water compared to the standard dyeing process.

Carbios has signed an agreement with On, Patagonia, PUMA, and Salomon, to develop solutions that will enhance the recyclability and circularity of their products.
 
An important element of the two-year deal will be to speed up the introduction of Carbios’ biorecycling technology, which constitutes a breakthrough for the textile industry. Carbios and the four companies will also research how products can be recycled, develop solutions to take-back worn polyester items, including sorting and dismantling technologies, and gather data on fiber-to-fiber recycling as well as circularity models.
 
The challenge the four brands share, is that their ambitious sustainable development goals can only partially be met by conventional recycling technologies which mostly target bottle-to-fiber recycling. Future regulations will require more circularity in packaging and textile. Yet the market consensus is that there will soon be a shortage of PET bottles, as they will be used for circular production methods in the Food & Beverage Industry.   
 
Carbios’ innovative process constitutes a technological breakthrough for the recycling of polyester (PET) fibers, which are widely used in apparel, footwear and sportswear, on their own or together with other fibers. PET polyester is the most important fiber for the textile industry with 52 MT produced, even surpassing cotton at 23MT. The biorecycling process uses an enzyme capable of selectively extracting the polyester, recovering it to recreate a virgin fiber. This revolutionary technology makes it possible to recover the PET polyester present in all textile waste that cannot be recycled using traditional technologies.
 
PET plastics and fibers are used to make everyday consumer goods such as bottles, packaging and textiles. Today, most PET is produced from fossil resources, then used and discarded according to a wasteful linear model. By creating a circular economy from used plastics and fibers, Carbios’ biorecycling technology offers a sustainable and more responsible solution.

With the goal of making recycling of lightweight, high-volume fiber and flake recyclate much more economical and, in some cases even possible, Coperion has developed a new version of its ZS-B side feeder. Using the innovative ZS-B MEGAfeed, plastic recyclate with a bulk density under 200 kg/m³, long considered intake-limited and thus not worth recycling, can be reliably fed in large quantities into Coperion’s ZSK twin screw extruder and be concurrently recycled and compounded.

The ZS-B side feeder’s novel design makes it possible to feed very high rates of fiber and flakes, such as PA, PE, PET, and PP. As a result, the ZSK twin screw extruder’s high capacity can be fully exploited when the ZS-B MEGAfeed is used. Very high throughputs in both mechanical and chemical recycling of post-industrial and post-consumer waste are achieved.

Increased Throughput in Numbers
With a ZSK 58 Mc18 twin screw extruder, the throughput increase and thus the potential of the new ZS-B MEGAfeed becomes very clear. When recycling PA fibers with a bulk density of ~40-50 kg/m3, throughputs of 70 kg/h were previously achieved using conventional equipment. When the PA fibers were fed into the ZSK extruder using the ZS-B MEGAfeed, throughputs increased about fourteenfold to 1,000 kg/h. Similar results were achieved recycling carbon fibers with a bulk density of ~50-70 kg/m3; in this case, throughputs increased from 50 kg/h to 2,500 kg/h using the ZS-B MEGAfeed. When recycling PCR (Post-Consumer Recycled) flakes, throughputs increased from 50 kg/h to 700 kg/h, and from 80 kg/h to 1,300 kg/h with multilayer film flakes.

Key to Economical Recycling of A Wide Variety of Plastics
Plastics previously considered not recyclable are becoming a valuable raw material using the new Coperion ZS-B MEGAfeed. For example, PCR flakes or recyclate from carbon fiber-reinforced plastics can now be fed into the ZSK extruder at high feed rates and recycled economically.

In the case of mechanical upcycling, upstream processes necessary for compounding, such as compacting, melting and agglomeration, are completely eliminated using the ZS-B MEGAfeed technology. In this recycling process, flakes and fibers can be fed directly into the ZSK extruder, where they are melted, compounded, devolatilized, and filtered in a single step. In so doing, both investment costs and energy consumption drop. The production process becomes significantly more efficient. Moreover, the thermal product stress is reduced and recyclate quality increases.

Even when recycling PET, the feed rate is no longer a limiting factor. With the ZS-B MEGAfeed, PET flakes and fibers can be fed into the ZSK twin screw extruder in large quantities with no pre-drying or crystallizing, where they can be processed with the highest degree of profitability.

The ZS-B MEGAfeed can also feed large quantities of post-consumer waste, adding appreciable value to the chemical recycling process with the ZSKs. ZSK throughput rates are very high with the ZS-B MEGAfeed. Preheating of the recyclate via mechanical energy input of the twin screws thus becomes even more economical for further processing in the reactor.

Existing Coperion extruders can be retrofitted with ZS-B MEGAfeed technology to greatly expand their spectrum of applications and increase their throughput rates.

The European Pultrusion Technology Association (EPTA) has published a report from its latest conference, which focuses on advances in sustainability and recycling.

More than 130 professionals from the global pultrusion community gathered at the 16th World Pultrusion Conference in Paris on 5-6 May 2022. Organised by EPTA in collaboration with the American Composites Manufacturers Association (ACMA), the event featured 25 international speakers sharing insight on market trends, developments in materials, processing and simulation technologies, and innovative pultruded applications in key markets such as building and infrastructure, transportation and wind energy.

‘Bio-pultrusion’:  
Composites based on natural fibres offer a number of benefits, including low density and high specific strength, vibration damping, and heat insulation. The German Institutes for Textile and Fiber Research Denkendorf (DITF) are developing pultrusion processes using bio-based resins and natural fibres. Projects include the BioMat Pavilion at the University of Stuttgart, a lightweight structure which combines ‘bamboo-like’ natural fibre-based pultruded profiles with a tensile membrane.

Applications for recycled carbon fibre (rCF):
The use of rCF in composite components has the potential to reduce their cost and carbon footprint. However, it is currently used to a limited extent since manufacturers are uncertain about the technical performance of available rCF products, how to process them, and the actual benefits achievable. Fraunhofer IGCV is partnering with the Institute for Textile Technology (ITA) in the MAI ÖkoCaP project to investigate the technical, ecological and economic benefits of using rCF in different industrial applications. The results will be made available in a web-based app.

Circularity and recycling:
The European Composites Industry Association (EuCIA) is drafting a circularity roadmap for the composites industry. It has collaborated with the European Cement Association (CEMBUREAU) on a position paper for the EU Commission’s Joint Research Centre (JRC) which outlines the benefits of co-processing end-of-life composites in cement manufacturing, a recycling solution that is compliant with the EU’s Waste Framework Directive and in commercial operation in Germany. Initial studies have indicated that co-processing with composites has the potential to reduce the global warming impact of cement manufacture by up to 16%. Technologies to allow recovery of fibre and/or resin from composites are in development but a better understanding of the life cycle assessment (LCA) impact of these processes is essential. EuCIA’s ‘circularity waterfall,’ a proposed priority system for composites circularity, highlights the continued need for co-processing.

Sustainability along the value chain:
Sustainability is essential for the long-term viability of businesses. Resin manufacturer AOC’s actions to improve sustainability include programmes to reduce energy, waste and greenhouse gas emissions from operations, the development of ‘greener’ and low VOC emission resins, ensuring compliance with chemicals legislation such as REACH, and involvement in EuCIA’s waste management initiatives. Its sustainable resins portfolio includes styrene-free and low-styrene formulations and products manufactured using bio-based raw materials and recycled PET.

Indorama Ventures, VALORPLAST, Klöckner Pentaplast (kp) and CITEO collaboration delivers a commercial recycling solution for monolayer PET trays

Thai-based Indorama Ventures Public Company Limited (IVL) with its facility Wellman France Recycling in Verdun, has been working on the PET trays recycling for 6 years and through an ongoing project with VALORPLAST and supported by CITEO.

The project has the objective to develop and validate recycling for monolayer and multilayer PET trays. VALORPLAST has collected significant quantities of post-consumer PET trays and several industrial runs have been conducted by Wellman. The produced flakes are being tested by several actors to develop high quality applications. Those tests have led by IVL to develop a commercially feasible recycling solution for monolayer PET trays with the collaboration of Klöckner Pentaplast.
The new technology is processing monolayer PET trays used for food packaging (meat, produce and cheese) into a high-quality product, suitable for new tray production.

This new recycling innovation will see over 50 million post-consumer PET trays diverted away from landfill or incineration.

Testing has now moved into commercial production. 500 tonnes of PET trays are now being processed monthly and transformed into a high-quality tray flake, which can be used to produce new trays. The purity of the flakes is comparable with high-quality bottle flake. A further scale up is foreseen, and the company plans to process 10KT of tray flake in 2022.

International textile producers meet again in Istanbul, Turkey, from June 14 – 18, 2022 on the occasion of the ITM + Hightex Exhibition. In Hall 9 (Hightex) the exhibitors will present the complete industry value chain from nonwovens raw materials, production machines and accessories to the endproduct. The related industries covered include hygiene, filtration, fabrics and apparel, medical, automotive, wipes, home furnishings and upholstery. DiloGroup offers tailor-made production systems from one supplier and will inform about its portfolio and the latest equipment developments from fibre opening to the finished felt.

DiloGroup will inform about complete lines as well as high speed needlelooms for spunbonds. A new, simplified elliptical needle beam drive makes Hyperpunch technology also attractive for standard application. Hyperpunch HαV allows a more uniform stitch distribution in the preneedling process especially in combination with the new needle pattern 6000X. In a complete needling line this felt homogenization process can be improved further. The new needle pattern 8000X is a milestone in the needle pattern development process and results in endproduct surfaces with low markings over a wide range of advances/stroke.

Another strong pillar of the sales program over decades has been fibre preparation and high speed webforming equipment for other nonwoven technologies. The further development of the high-speed layering principle “Hyperlayer” made progress for better CD strength through a combination of inline cards and crossline card with crosslapper. Particularly, carding machines in a working width above 3.5 m up to 5.1 m have been supplied by DiloSpinnbau as complete high speed carding systems, comprising two or even three cards in a line to directly feed the hydroentangling units of various suppliers. Together with DiloTemafa not only have high throughput rates been achieved in the fibre preparation section of the line but also dedusting filtering and air-conditioning systems have been successfully engineered and integrated.

Together with Sicam, Dilo has combined know-how for hydroentangling technology and therefore can provide complete lines as general contractor including equipment for cutting, winding and packaging.

Another interesting machine is the 3D-Lofter, first presented during ITMA 2019 in Barcelona, which offers a wider range of nonwovens applications by exploring the third dimension. A series of single web forming units which work according to the aerodynamic web forming principle deliver defined fibre masses in varied patterns on a base needlefelt. A stress oriented production of technical formed parts resulting in fibre savings or patterned DI-LOUR or DI-LOOP felts with or without repeat are two examples for this technology which explores new application areas for needlefelts.
The 3D-Lofter technology may also be used “inverted” as “IsoFeed” for filling up bad spots in web mats and thus achieves a better homogeneity of spunlace or airlay products.

The DiloLine 4.0 concept offer I4.0 modules which not only support the user but also facilitate quality control and maintenance by a maximum data transparency in production and control of operation. The Dilo solutions “Smart Start” for a fully automatic start of the production line or “DI-LOWATT” for energy savings are accompanied by Siemens solutions which can be selected via App or Data Cloud “MindSphere”.

• Sustainable infrastructure solutions, road safety and health protection

At this year’s Techtextil, Oerlikon Polymer Processing Solutions will be presenting the trade audience with new applications, special processes and sustainable solutions focusing on the production of industrial textiles. Among other things, the company will be showcasing new technology for charging nonwovens that sets new standards with regards to quality and efficiency. Between June 21 and 24, the discussions will be concentrating on airbags, seat belts, tire cord, geotextiles, filter nonwovens and their diverse applications.

More polyester for airbags
Airbags have become an integral part of our everyday automotive lives. The yarns used in them are made predominantly from polyamide. As a result of increasingly diverse airbag applications and also the increasing size of the systems used, polyester is today used as well, depending on the application requirements and cost-benefit considerations. Against this background, the Oerlikon Barmag technologies make an invaluable contribution. In addition to high productivity and low energy consumption, they particularly excel in terms of their stable production processes. Furthermore, they comply with every high quality standard for airbags, which – as in the case of virtually all other textile products used in vehicle construction – must provide the highest level of safety for vehicle occupants. And all this without any loss of function in any climate and anywhere in the world for the lifetime of the vehicle.

Buckle up!
Seat belts play a decisive role in protecting vehicle occupants. They have to withstand tensile forces in excess of three tons and simultaneously stretch in a controlled manner in emergencies in order to reduce the load in the event of impact. A seat belt comprises approximately 300 filament yarns, whose individual, high-tenacity yarn threads are spun from around 100 individual filaments.

Invisible, but essential – road reinforcement using geotextiles
But it not just inside vehicles, but also under them, that industrial yarns reveal their strengths. Low stretch, ultra-high tenacity, high rigidity – industrial yarns offer outstanding properties for the demanding tasks carried out by geotextiles; for instance, as geogrids in the base course system under asphalt. Normally, geotextiles have extremely high yarn titers of up to 24,000 denier. Oerlikon Barmag system concepts simultaneously manufacture three filament yarns of 6,000 denier each. Due to the high spinning titers, fewer yarns can be plied together to the required geo-yarn titer in a more cost- and energy-efficient manner.

hycuTEC – technological quantum leap for filter media
In the case of its hycuTEC hydro-charging solution, Oerlikon Neumag offers a new technology for charging nonwovens that increases filter efficiency to more than 99.99%. For meltblown producers, this means material savings of 30% with significantly superior filter performance. For end users, the consequence is noticeably improved comfort resulting from significantly reduced breathing resistance. With its considerably lower water and energy consumption, this new development is also a future-proof, sustainable technology.

New high-tech Staple Fiber Technology Center
Extending to around 2,100 m2, Oerlikon Neumag in Neumünster is home to one of the world’s largest staple fiber technology centers. As of now, these state-of-the-art staple fiber technologies are also available for customer-specific trials.

The focus during the planning and the design of the Technology Center was on optimizing components and processes. Here, special attention was paid to ensuring the process and production parameters in the Technology Center system could be simply and reliably transferred to production systems. Here, the fiber tape processing line is modular in design. All components can be combined with each other as required. And comprehensive set-up options supply detailed findings for the respective process for various fiber products.

The Technology Center is also equipped with two spinning positions for mono- and bi-component processes. The same round spin packs are used for both processes, characterized by excellent fiber quality and properties and meanwhile very successfully deployed in all Oerlikon Neumag production systems. Furthermore, the spinning plant is complemented by automation solutions such as spin pack scraper robots, for example.
