From the Sector

On June 1, EREMA hosted the EREMA Discovery Day focusing on the post consumer segment from a European perspective. Live demonstrations showcased the latest machine innovations for PET and polyolefin recycling.

The invitation was accepted by around 400 customers and partners, mainly from Europe, to find out about the wide range of recycling technologies for PO and PET plastic waste. The technology that was presented and explained by EREMA experts and guest speakers during lectures in the morning, could then be seen live in-action in the afternoon when the recycling machines were demonstrated in operation. A total of six innovative recycling technologies were on display: INTAREMA® TVEplus® DuaFil® Compact, INTAREMA® TVEplus® RegrindPro® + ReFresher, the COREMA® cascade extrusion system, a VACUREMA® Inline Sheet line equipped with new EcoGentle technology, the new INTAREMA® FibrePro:IV machine, and the PCU-
TwinScrew. These allowed visitors to witness their performance and the high quality of recycled pellets that they produce.

"This wide range of technologies is necessary because the recycling process each of our customers choose depends on the type of plastic, the level of contamination of the input material, and which product will be made using the recycled pellets. Following the expansion of our Ansfelden site and with the new site nearby in St. Marien, we can now demonstrate all these processes, carry out test runs with customers' material and focus on development work independently of our Customer Centre," says EREMA's Managing Director Markus Huber-Lindinger.

EREMA is driving forward research and development work in the company's new R&D Centre. Two halls with a total area of 1,550 square metres and a new office building offering space for 50 workplaces has been built. Here, the company bundles cross-departmental test machines and laboratory facilities for post consumer and inhouse recycling applications. R&D is decentralised at EREMA. Employees from different departments handle process engineering challenges, innovations in mechanical engineering and automation technology - all with the aim of meeting customer requirements and achieving the highest possible quality of recycled pellets.  

On the evening before Discovery Day, EREMA celebrated its 40th anniversary together with customers and partners. A review covered the company's history - from the first workshop in a garage in 1983, to its position today as a innovation pioneer and one of the market leaders.

• Strategic partnership for automation system in the field of slot dies and coextrusion adapters

Reifenhäuser Extrusion Systems (RES) - the Reifenhäuser Group's business unit specializing in extrusion components - announces a strategic partnership with maku AG at K 2022, the world's largest plastics trade fair. The aim of the cooperation is the joint marketing and further development of the automation system designed by maku for coextrusion adapters and slot dies.

The so-called PAM system (precise, autonomous, mechatronic) is available immediately and exclusively as an automation option for new Reifenhäuser dies and adapters, as well as for aftermarket dies across all manufacturers. PAM enables producers in the field of flat film and sheet production as well as extrusion coating to precisely control the entire hot part (coextrusion adapter and die) via the line's control panel. This is significantly faster and more accurate than conventional control by hand or expansion bolt automation. It enables faster start-up of good production, higher output with lower energy consumption, and thus significantly improved overall equipment efficiency (OEE). The decisive advantage lies in the use of motorized manual adjustment bolts that replace conventional thermal expansion bolts. Reifenhäuser presented the system for the first time at the K 2022.

Standard & Poor's Global Ratings (S&P) raises its long-term rating for SGL Carbon to B- and its issue rating on its financial instruments to B. The outlook for the company is rated as stable by the renowned rating agency.

S&P Global Ratings explains the upgrade of SGL's rating with the company's improved capital structure and the reduction of net debt. The rating agency expects SGL Carbon to generate positive free cash flow in the coming years, which will support the reduction in absolute debt.

For the future development of SGL Carbon, S&P assumes an improvement in profitability based in particular on the expansion of products and materials for the future-oriented core markets of mobility, energy transition and digitalization, besides the savings from the restructuring.

"We are pleased that our operational successes and the already advanced trans-formation of SGL Carbon have been honored by the two major rating agencies - Moody's and S&P - by upgrading the ratings. We also see this as a motivation for the further development of SGL Carbon," explains Thomas Dippold, Chief Financial Officer of SGL Carbon SE.

• Innovation begins with creativity
• A pioneer of the manmade fiber industry

When the manmade fiber age began a century ago, a German company was responsible for the pioneering work involved. Barmag, established in 1922, was one of the world’s first companies to construct machines for the large-scale production of synthetic staple fibers. To this day, the leading manufacturer of manmade fiber spinning systems and texturing machines in Remscheid – a brand under the aegis of the Swiss Oerlikon Group since 2007 – has shaped technological progress in this sector; in future, with ever more innovations focusing on sustainability and digitalization.

Barmer Maschinenfabrik Aktiengesellschaft (Barmag) is founded in Barmen, located in the Bergische Land region, on March 27, 1922. The German and Dutch founders enter unchartered technological territory, one created as the result of a groundbreaking invention: in 1884, French chemist Count Hilaire Bernigaud de Chardonnet used nitrocellulose to produce the first so-called artificial silk, later known as rayon. The following decades see rapid development focusing on the search for synthetic textile fibers and their manufacturing technologies. As one of the first machine factories, Barmag battles its way through the eventful early years of the manmade fiber industry, the ‘Roaring Twenties’ and the Great Depression – and suffers the extensive destruction of its factories at the end of World War Two. Rebuilding is successful. With the unstoppable success story of purely synthetic plastic fibers such as polyamide, the company flourishes from the 1950s through to the 1970s, establishing sites in all international, for the textile industry at the time important, industrial regions and garnering prestige across the globe in the process. In the ups and downs of expansion, global competition and crises, Barmag reaches the very pinnacle of the market and becomes the preferred technological development partner for the manmade fiber industries in China, India and Turkey. The company has been a high-impact brand under the umbrella of the Oerlikon Group since 2007.

On the wings of innovation
Today, Oerlikon Barmag is a leading supplier of manmade fiber filament spinning systems and part of the Manmade Fibers Solutions business unit of the Oerlikon Polymer Processing Solutions Division. And our aspirations have not diminished: “The striving towards innovation and technological leadership has been, is and will always be part of our DNA”, emphasizes Georg Stausberg, CEO of Oerlikon Polymer Processing Solutions. In the past, this has been observable in such trailblazing innovations as the revolutionary WINGS generation of winders for POY in 2007 and WINGS for FDY in 2012. Currently, the focus of new and further developments is very much on digitalization and sustainability. Here, Oerlikon Barmag has – as one of the world’s first systems manufacturers – been implementing fully-networked smart factories for globally-leading polyester manufacturers since the end of the last decade. Within this context, digital solutions and automation are also helping to provide greater climate and environmental compatibility. This sustainability commitment is not only evidenced by the e-save label introduced for all products back in 2004: Oerlikon is endeavoring to also make all its sites carbon-neutral by 2030 and to acquire its energy exclusively from renewable sources. An ambitious target, whose achievement could be helped by the Oerlikon Barmag anniversary, states Georg Stausberg: “Innovation begins with creativity. And remembering the past provides plenty of motivation and inspiration for the future.”

• Hightech textiles for future-oriented construction projects

Building shells, bridges, staircases, façades ... construction projects are exposed to enormous mechanical loads. Often there are also considerable climatic or environmental influences. This has prompted the increasing use of fibre-reinforced materials in construction projects. After all, besides many other exciting properties, they offer high mechanical rigidity, low weight and excellent corrosion resistance.

Tapes, tubulars, sections and 3D woven textiles by vombaur form the perfect basis for these innovative building materials. The seamless round or shaped woven narrow textiles made of high-performance fibres are extremely loadable because they have neither seams nor welds – and therefore no undesirable breaking points. Their surface properties are identical over the entire length. In challenging tasks, composite textiles by vombaur offer a lightweight solution that is as reliable as it is durable.

Safe and durable solutions for challenging applications
The potential applications for lightweight components in the construction industry are as numerous as the project ideas of the planning and construction teams.
•    Ropes and tensioning elements made of carbon fibre reinforced plastic (CFRP)
•    Reinforcement of building structures made of concrete, steel, wood or other materials
•    Sustainable restructuring of constructions and urban districts for bridges and buildings
•    CFC slats as reinforcements in case of repairs
•    (Filled) GRP pipes made of seamless round woven tubes by vombaur as columns/pillars
•    CFRP sections as steel girder substitutes
•    Hollow profiles with individually designed cross-sections
•    Glass fibre reinforced connecting elements for glazing to minimise expansion differences between the connecting element and the glass
•    Individual light wells

Originally conceived as a low-cost, high-volume alternative to knitting and weaving, nonwovens was already expanding its market boundaries by the 1970s with new applications in ‘disposables’ such as diapers, hygiene and teabags.

In the past five decades, the nonwovens business has exploded in all directions, reaching a global market worth USD 40.5 billion in 2020, projected to grow to USD 53.5 billion by 2025. This annual growth rate of 5.7% (MarketsandMarkets, Nonwoven Fabric Market Report) is based on countless new applications and expansion into durable, as well as additional disposable, products.

Major growth drivers include the hygiene sector, and filtration media for power plants and air conditioning systems. Especially during the peak of the COVID pandemic in 2020 and 2021, demand in the hygiene sector multiplied. Worldwide capacities for both meltblown and spunlace production rocketed compared to a normal business year. Swiss Autefa Solutions, for example, significantly benefited from this trend, notably with the launch of a fully-automatic machine for producing face masks.

The automotive industry is the second big growth area, with many new applications being pioneered. The trend to electric and hybrid vehicles has helped this, as nonwovens reinforced with carbon fibres are widely used as battery housings.

Swiss nonwovens competence
Innovative applications across all sectors have driven the rapid evolution of sophisticated nonwovens machinery. Today’s trends demand higher productivity, sustainability and Industry 4.0 compatibility – demonstrated by the full equipment portfolio of Swiss Textile Machinery member Autefa Solutions. With V-Jet Futura, the company recently sealed the link in its product range between web forming and drying technology. This latest Hydroentanglement Machine, together with the SQ-V Square Drum Dryer, embodies advanced technology combined with significant reductions in energy consumption compared to other process solutions.

A vital contribution to nonwovens production is offered by Rieter subsidiary Graf, a leading supplier of clothing and combs for carding and combing processes in spinning and nonwovens. Graf's Hipro card clothings – suitable for any man-made fibres in the nonwovens sector – are focussing on higher productivity. Their superior performance delivers up to 10% higher throughput and greater carding efficiency compared to conventional clothings. These reliable card clothing elements also ensure a consistently reproducible high web quality, as well as 20% fewer failures in the web, thanks to the precise fibre transfer to and from the cylinder.

Another constant trend in nonwovens today is the drive for better quality. Manufacturers want to take charge of contamination levels in their processes, as well as eradicating defects which may arise during production. Uster Technologies, a leading provider of quality management solutions from fibre to fabric, offers a combined solution to achieve both these required quality standards. At the fibre preparation stage, Uster Jossi Vision Shield N ensures the best possible initial inspection and removal of contamination. Then, at the end of the production sequence, Uster EVS Fabriq Vision N handles automated detection and marking of all the main defects caused during production. This combined solution avoids material waste and takes full advantage of the potential for process optimization.
