• 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.

• On October, 20th, 2020, the State Prize for Innovation was awarded to the Lenzing Group for their LENZING™ Web Technology.
• Lenzing thus received the highest award for particularly innovative achievements in Austria.

Lenzing – On Tuesday, October 20, 2020, the Lenzing Group was awarded the coveted “State Prize for Innovation”. Lenzing emerged as the winner with its project LENZING™ Web Technology and thus received the highest recognition for particularly innovative achievements in Austria. The novel process combines fiber and nonwovens production in only one step, setting new standards in terms of efficiency, circularity and ecological sustainability. Margarete Schramböck, Federal Minister for Digital and Economic Affairs, presented the award to Gert Kroner, Vice President Global Research & Development.

“This award is a great recognition of our work. Our goal is to grow continuously with sustainable innovations and to look beyond our fibers, to the needs of our customers and partners and to the needs of consumers worldwide. With the LENZING™ Web Technology we have created an exciting and promising solution for eco-friendly products in line with our corporate strategy sCore TEN and support consumers in their daily needs in a sustainable way”, says Stefan Doboczky, Chief Executive Officer of the Lenzing Group.

Biodegradable nonwovens for a clean environment

The pollution of the environment by plastics is one of the most urgent problems of our time. Every day, millions of hygiene products and wipes around the globe end up in garbage and sewage. Most of them consist of up to 80 percent polyester or other fossil, non-biodegradable materials and therefore pollute the environment. With the LENZING™ Web Technology, Lenzing has developed a patented technology to counter this problem: Sustainable and eco-friendly nonwovens are produced from the renewable raw material wood. These are not only plastic-free, they also score points for their particularly high environmental friendliness. “Thanks to a unique self-bonding mechanism, in which the filaments bond with each other during the spinning process, binders, which are found in many nonwovens, are no longer needed. As a result, the nonwovens produced with LENZING™ Web Technology are 100 percent biodegradable and do not pollute either humans or the environment”, says Gert Kroner, Vice President Global Research & Development of the Lenzing Group.

The Austrian State Prize for Innovation is awarded annually by the Federal Ministry for Digital and Economic Affairs to the most innovative Austrian company. In 2020, the competition took place for the 40th time.

• World Cotton Day on 7 October Highlights the Importance of Cotton for Development Policy

Bremen - Stemming from a 2019 initiative of the African Cotton-4 countries Benin, Burkina Faso, Chad and Mali, World Cotton Day will take place this year on 7 October. The event is organised by the Geneva-based World Trade Organisation (WTO) and is supported by the Food and Agriculture Organisation of the United Nations (FAO), the United Nations Conference on Trade and Development (UNCTAD), the International Trade Centre (ITC) and the International Cotton Secretariat (ICAC). The Bremen Cotton Exchange is also involved.

“Cotton is often underestimated because it is so natural. Behind it are millions of people, for example many farmers, field workers, employees in ginning factories, logistics providers and traders. We want to honour their achievements,” said the President of the Bremen Cotton Exchange, Stephanie Silber.

According to the WTO, the aim of World Cotton Day is to highlight the global economic importance of cotton and to raise awareness of the raw material by recognising the work of everyone involved in its cultivation, processing and trade. At the same time, within the framework of international cooperation, it is hoped that supporters and investors can be found to aid with technological and economic progress within the cotton value chain.

This time, the entire world cotton community will be involved in World Cotton Day on Wednesday, 7 October 2020. A wide variety of campaigns and events are taking place everywhere to draw attention to the importance of cotton and its possible uses.

Cotton is one of the most relevant agricultural raw materials in the world. Around 26 million tonnes of it are harvested annually. Approximately 150 million people in almost 80 countries around the world live from the cultivation of the natural fibre. A large number of these live in developing countries, where cotton cultivation is of particular importance as a cash crop.

Cotton is known as an agricultural product that is turned into a textile. The raw material is indispensable in fashion and clothing – and has been for thousands of years. But the use of cotton now goes far beyond textiles. For example, cosmetic products such as hand creams and hair shampoo are made from the oil of cotton seeds. The raw material is also used in the manufacture of banknotes, furniture and technical textiles, as well as in medical technology.

Against the background of the current discussion on sustainability and sustainable consumption, the role of natural fibres is becoming even more important. Cotton is biodegradable and a renewable resource. It can be grown again and again in agriculture through cultivation in crop rotation. This secures incomes and enables efficient value creation within the global production and processing chain.

The Bremen Cotton Exchange will actively support World Cotton Day with cross-media coverage. In addition, in time for World Cotton Day, three thematically different, emotionally appealing short films about cotton will be launched. They are aimed at consumers as customers of the textile and clothing trade and provide information about the benefits and properties of cotton and answer questions about its sustainability. In keeping with the times, they will be published via virtual media.

Optimum wool dyeing solution aligned to ZDHC MRSL standards

Singapore – Huntsman Textile Effects’ LANASOL® CE dyes, provide the industry with the sustainable alternative to after-chrome dyes for wool. LANASOL® CE dyes offer a consistent, safe and reliable dyeing process that can effectively replace chrome dyes for wool. This helps mills conform to ZDHC MRSL standards and meet the stringent requirements of global brands and retailers.
The use of Chrome VI, including Dichromate, is banned in the ZDHC Manufacturing Restricted Substances List (ZDHC MRSL). Wool processors working for brands and retailers that have adopted ZDHC MRSL must therefore act quickly to finalize their chrome replacement developments.

Developed by Huntsman Textile Effects specifically to meet these challenges, LANASOL® CE is a state-of-the-art chrome-free dye range that allows mills to discontinue the use of after-chrome dyes. LANASOL® CE outperforms traditional after-chrome dyes across the board – at every level of dyeing and processing.

“LANASOL® CE dyes have always been recognized as the leading brand in the wool industry. Our innovative dyeing auxiliaries and successful dyeing systems with LANASOL® CE provide the highest technical performance, helping customers to protect the natural beauty of wool, achieve water, energy and time savings while rendering chrome dyes obsolete,” said Alessandro Larghi, Global Marketing Manager for Wool at Huntsman Textile Effects.

As a champion of a sustainable textile industry, Huntsman Textile Effects has long been a strong advocate for the shift away from after-chrome dyes. Huntsman Textile Effects first introduced LANASOL® CE in 1997, before the introduction of any regulation on the restricted use of dichromate.

Following the successful commissioning of two new Monforts Montex wide-width stenter lines and additional environmental management equipment at its plant in Germany, GtA – Society for Textile Equipment GmbH – is aiming to be the first textile finishing company to become entirely CO2-neutral in the manufacture of all of its products by 2025.

GtA is a partner company to Germany’s large-format digital printing fabric leader, Georg and Otto Friedrich GmbH, which has has this year been able to considerably expand its portfolio due to the new Monforts lines.

Headquartered in Gross-Zimmern, close to Frankfurt, Georg and Otto Friedrich GmbH and its partners in Germany have an annual production of 37 million square metres of warp knits for a range of end-use applications, including garments, automotive interiors and technical textiles, but increasingly with a concentration on digital printing substrates.

Fault-free textiles

A new standard in pure white, 100% clean and fault-free textile substrates has been demanded by this market in recent years due to the rapid growth in digitally-printed banners and billboards – often referred to as ‘soft signage’.

The substrates of choice for digital printing are 100% polyester warp knits which are resilient and allow excellent take-up of inks, and vibrant colours and clear and precise images to be achieved with digital printing techniques. The knitted construction also has the advantage of elasticity, which is a plus in terms of flexibility for installers.

Critically, the warp knitted fabrics have extremely smooth surfaces which is becoming increasingly important due to the general move away from PVC coatings which were the standard in the past.

It was to finish these fabrics for Georg and Otto Friedrich GmbH as well as providing such services for many other customers, that the GtA plant in Neresheim, Baden-Württemberg, was established in 2015.

The purpose-built plant on a greenfield site was initially equipped with a fully-automated, 72 metre long Monforts installation comprising a washing machine integrated with a 3.6 metre wide, seven-chamber Montex stenter. The line quickly went from single to double shift production and then to 24/7 operation  to meet demand.

Expanded widths

Building on the success of this installation, GtA has now installed two more Montex stenter lines – both in expanded working widths of 5.6 metres and purpose-built at Montex GmbH in Austria.

A six-chamber Montex unit is combined with a washing machine to guarantee the purity of the substrates, while a five-chamber line is integrated with a wide-width coating machine. This new coating capability at GtA has led to a number of new additions to the Georg and Otto Friedrich DecoTex range for digital printing, including wide width fabrics with flame retardant, antimicrobial and non-slip finishes.

The new Montex stenter lines benefit from all of the latest innovations from Monforts, including the Smart Sensor system for the optimised maintenance planning of key mechanical wear components on the stenters. A comprehensive overview of the condition of all parts at any time is now available for operators within the highly intuitive Qualitex visualization software.

With Qualitex, all article-specific settings can be stored and the formulations for thousands of treatment processes called up again at any time. Individual operators can also personalise their dashboards with the most important machine functions and process parameters.

Environmental commitment

GtA is run by a seasoned team of textile professionals led by Managing Director Andreas Niess.

“We have received excellent service from Monforts from the outset and we were happy to place the order for these two new lines as part of our ongoing cooperation,” he says. “With all of the latest Monforts advances in technology we are fully in control of all production and quality parameters with these lines, as part of our significant commitment to innovative environmental technology.”

The GtA plant, which operates in near-cleanroom conditions, has also been equipped with proprietary technology to fully exploit the Monforts air-to-air heat recovery systems that are now standard with Montex stenters.

“Around 30 per cent of our investment volume at the site goes to energy-saving measures and we are sure that this commitment is worthwhile,” Mr Niess says. “As an example, our integrated heat recovery system fully exploits the waste heat from the process exhaust air and the burner exhaust gases of the Monforts stenters, allowing us to achieve an exhaust air temperature of  between 30 to 34°C, compared to what would conventionally be between 140 to 160°C. Another focus has been on exhaust air purification technology and here too, the latest technology has been installed with integrated heat recovery elements.”

This, he adds, saves 52% of the energy that would normally be used – equating to 5,800,000 KwH per year. The necessary audits for energy-efficient companies are also carried out annually.

In addition, GtA has purpose-designed the automatic chemical mixing and dosing systems that feed the padders for the key treatments that are carried out on the fabrics through the stenters.

The company is going further, however, in its pursuit of clean production and raw materials.

"We want to be an asset and not a burden on our immediate environment and therefore do not use any additives containing solvents," Mr Niess says. “We were the first to use fully halogen-free flame retardant chemistry, and we use bio-based, finely ground alumina products for the washing process instead of surfactants. PES polyester yarns made from recycled material are also increasingly used and the latest additions to our raw materials portfolio, the RC-Ocean products, are made from recycled sea plastic.

“We are now planning a combined heat and power plant for the production of electrical energy and heat and we will also build a photovoltaic system that converts solar radiation into electrical energy. GtA wants to be the first textile finishing company to be CO2-neutral in the manufacture of all of its products by 2025. The complete heat supply and heating for the 13,000 square metre production hall, as well as the office building and the hot water supply for the domestic water, is already energy-neutral. We are convinced that this commitment will pay off in the long term and our positive business development proves that sustainability and business profitability are perfectly compatible.”

In addition to the products for Georg and Otto Friedrich GmbH, GtA  offers its manufacturing capacities for other customers as a contract service.

All products are manufactured in accordance with Öko-Tex Standard 100, product class 1 and the company is also involved in the research and development of new sustainable manufacturing processes, in cooperation with many regional universities and funding project partners.

• "Even closer to our customers"

After more than eight years in the Intercontinental Business Center on Yutong Road in Shanghai, China, the Manmade Fibers segment has now opened a new sales and service office in the metropolis of millions near the international airport in Hongqiao and the National Exhibition and Convention Center (NECC).

The Manmade Fibers segment in China now officially operates under the following address:

Oerlikon (China) Technology Co. Ltd.
Shanghai Branch
RM1208-1210, Tower A, The Place,
100 Zunyi Road, Changning District
Shanghai China 200051

The main reason for the change from Yutong Road to the new address on Zunyi Road was the logistical aspects in a city that has had to cope with increasingly heavy traffic in recent years. "Now we are even closer to our customers," explains Wang Jun, Oerlikon China President. The proximity to Hongqiao airport and the Hongqiao railway station with its high-speed trains will provide the sales and service staff with even better infrastructure connections.

Furthermore, the local repositioning also takes into account the changes within the Oerlikon Group. "The divestments made within the Oerlikon Group in recent years have now led to a reorganization here in Shanghai. Today, Oerlikon's business activities in China focus exclusively on the segments Manmade Fibers and Surface Solutions incl. Additive Manufacturing. The time had come to set up the best possible infrastructure for optimum customer service for both business segments," continues Wang Jun. In addition, in the age of digitalization, sales and service employees in China are increasingly able to work from home. All of this has now led to a changed, adapted and, last but not least, cost-optimized reorganization.

Less wear and superior fiber quality
Technological changes to Oerlikon Neumag’s Baltic crimper thrust pad contacting device have resulted in considerably reduced friction in the crimper rolls and hence less wear and fewer metal particles contaminating the crimped staple fibers.
Thrust pads close the gap between the crimper rolls on either side. Normally, these thrust pads are continually pressed – under high pressure – against the sides of the crimper rolls. Wear and metal debris on the thrust pads is the result of this constant contact. The metal debris can contaminate the fibers, something that is particularly undesirable in hygiene applications.

New thrust pad contacting device for reduced metal debris and greater durability
With the new system, the thrust pads are pressed against the rolls with less pressure and then fixed into place. This prevents fibers from being caught and the frictional force between the pressure disk thrust pad and the crimper roll is minimized. Pilot applications have demonstrated that metal debris from the pressure disks thrust pads is dramatically reduced, making them durable.

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.
