• 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.

Neumünster – Success is built by connecting the right people with the right product. In a global marketplace, this means collaboration is just as important as competition. Companies need to focus on their strengths, while finding practical ways to innovate and expand upon their capabilities.

An exclusive license from Procter & Gamble offers the best for nonwovens

In order to do so, working together often makes the most sense. This is what motivated Procter & Gamble and Oerlikon Nonwoven – Teknoweb Materials to agree on an exclusive license agreement to market and sell the Phantom platform worldwide.

The patented process for hybrid nonwovens combines the best of both airlaid and spunmelt technologies to deliver new, flexible ways of creating wet and dry wipes. Phantom technology offers additional benefits by reducing resources and cost, while increasing overall performance. The exclusive license gives Oerlikon Nonwoven – Teknoweb Materials distribute this technology worldwide. In addition, Oerlikon Nonwoven – Teknoweb Materials have further refined the process into their own Levra technology – an entry-level option which offers tailored production volumes with lower investment costs but is still suitable to be upgraded to the premium Phantom model in the future.

Quality products that cost less

Essentially, Phantom technology was developed to produce hybrid substrates. The spunmelt and airlaid processes are merged into one step to combine cellulose fibers, long fibers such as cotton, or even powders with polymer fibers in unprecedented ways. This technology has clear advantages in terms of resources, performance, and cost compared to the previous processes on the market. By removing hydroentanglement, it is no longer necessary to dry the material. Adjusting the process can optimize relevant product characteristics such as softness, strength, dirt absorption, and liquid absorption. In the end, this even increases the quality of the product itself.

The greater freedom for formulating continuous and discrete fibers allows for more flexible and absorbent structures and highly textured materials. Wipes feel softer to the touch while providing more protection for the hands. Up to 90% of the material can consist of pulp fibers, although natural alternatives like cotton or synthetic fibers can be added to the mix.

Phantom technology has not only found a practical application in a variety of wipes – such as hygiene wipes, anti-bacterial wipes, surgical wipes, or industrial wipes – but also in absorbent cores, for instance indiapers or fempro products. With so many applications, Oerlikon Nonwoven – Teknoweb Materials are fully prepared to deliver Procter & Gamble’s innovative Phantom technology to the global nonwovens market.

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".

• 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.

• The CHT Group is constantly expanding its sustainable product range for a circular economy according to the Cradle to Cradle principles

Progress in itself does not necessarily have to be sustainable but in the CHT Group it certainly does. For this reason the company has defined progress more precisely. The developers and chemists from Tübingen show true inventive talent with sustainable innovations.

According to the CHT Group's self-perception, sustainable innovation always includes a responsibility component for the future. With decades of experience along the textile value chain, the globally active CHT Group offers an incomparably wide range of services focusing on sustainable, resource-saving and forward-looking speciality chemicals and the efficient shaping of textile processes.

The circular economy takes over a decisive role: In the CHT Group we are convinced that recyclable textile products are the right means to protect resources and reduce the environmental impact. Therefore, our team works closely with textile manufacturers and brands to achieve the common goal of avoiding waste and harmful substances along the textile production process and thus producing more ecological textiles.

The Cradle to Cradle approach provides a trend-setting concept in the textile world that perfectly fits the company's sustainable strategy: Right from the start products shall be created which are suited for the biological (compostable) or technical (recyclable) circulation.

The CHT Group focuses on the development of dyes, pigments and auxiliaries for textile finishing which can be decomposed without leaving any residues and easily returned to the natural circulation.

For textiles which are to be developed and produced strictly according to the Cradle to Cradle principle, CHT offers a comprehensive, constantly growing, compostable range for textile finishing. With 57 textile auxiliaries and 32 dyes/pigments CHT has succeeded in achieving the highest rating, the Platinum Material Health Certificate of the Cradle to Cradle Products Innovation Institute.

These products help textile manufacturers to achieve the Platinum rating in Material Health, one of five categories of the Cradle to Cradle Certified™ product standard on finished textiles. This contributes to giving textiles a positive ecological footprint.

Textiles can be given the decisive distinguishing feature through the Cradle to Cradle Certified™ product standard. Cradle to Cradle Certified™ is the world's leading science-based standard for safe, recyclable and sustainable materials and products. CHT offers the possibility of designing tomorrow's sustainable textiles already today and is therefore part of the Circular Economy.

Cradle to Cradle Certified™ is a registered trademark of the Cradle to Cradle Products Innovation Institute.

• Gorilla Protect is a new company formed in May this year to promote the Catus face mask – a major leap forward in the effectiveness of personal protection products that are available to consumers in the fight against Covid-19.
• Behind Catus and the new company is Nova Textil, the established fabric finishing company based in Grefrath, Germany, and now run by father and son team Rainer and Oliver Hurtz.

Single stenter

Rainer Hurtz founded Nova Textil with a single Monforts Montex stenter and just five employees in 1999 and has steered its constant development and growth over the past twenty years.

“Our initial focus was on the coating of mainly glass fibre fabrics, awnings and sun protection products for outdoor furnishings,” he said. “We had a great customer who was providing us with so many orders that by 2005 we took the decision to order a second Montex stenter, in a special configuration. This also allowed us to enter the market for blackout and digital printing fabrics. We’ve had a great ongoing relationship with Monforts from the beginning.”

A third Montex stenter line was installed at the company’s Grefrath plant in 2015, by which time the company had grown to 40 people and a major new market had opened up in the supply of fabrics for promotional materials at exhibitions and trade shows.

“We had a fantastic two years in 2018 and 2019 and everything was going great for the first three months of this year, but in April it all came crashing down,” said Oliver Hurtz. “Coronavirus put an end to trade shows in 2020, which had a very serious impact on our business.”

At the same time, however, the company was exploring the potential of a new biocidal product from one of its chemicals suppliers which has both antiviral and antimicrobial properties.

Filtration

“We had already been producing coated fabrics for hot gas filtration and realised that in combination with this new microporous coating we had the basis for a very effective single-layer face mask,” Rainer said. “Achieving this with a single layer product rather than the usual three has resulted in a significant advance in comfort for the wearer and because the mask is able to disinfect itself and helps regulate humidity, it can be worn a number of times without needing to be washed, for greater convenience. It only needs to be washed when it gets dirty and can also be washed up to twenty times without losing its properties, which has to be preferable to single-use disposables.”

Catus face masks are based on 100% woven cotton and the active ingredients in the finish are a reaction mass of titanium dioxide and silver chloride certified to ISO 20743 for their antibacterial effect, and to ISO 18184 for their antiviral effect.

They are proven to  eliminate over  99.99% of the human coronavirus 229 E, with the multiplication of microorganisms such as germs and bacteria prevented by the biostatic action of silver salts and viruses destroyed by oxygen-releasing substances and a mechanism that attacks their fatty envelope. The virus membrane loses its cholesterol content and the virus is inactivated.

Colours

Gorilla Protect next plans to make the masks available in four colours – black, Bordeaux, olive and grey – and is also working on colour branding and printing labels.

“It’s not possible to print on the surface of the mask after it has been coated, but its is possible for volume orders to be printed before the treatment,” Oliver Hurtz said.

“Face masks are going to become an established part of life in the West like they are in Asia and need to be as comfortable and convenient as possible for the wearer,” his father concluded. “With these things in mind, we believe Catus is a significant step forward.”

Rester Oy, which is developing the plant in Paimio, recycles companies' end-of-life textiles, and Lounais-Suomen Jätehuolto Oy (LSJH), which will hire a production area at the same facility, processes households' end-of-life textiles. The plant will process 12,000 tonnes of end-of-life textiles every year, which represents about 10% of Finland’s textile waste.

The textile industry’s end-of-life textile problem is intolerable. Natural resources are increasingly used to manufacture products, but these materials are lost at the end of their life cycle. About 100 million kilograms of textile waste are generated annually in Finland alone. Reusing this material could reduce the textile industry’s carbon footprint and significantly reduce the use of natural resources.

Rester Oy and LSJH will drive the textile sector towards a circular economy and begin processing textile waste as an industrial raw material. The Nordic countries’ first industrial end-of-textile refinement plant will open in Paimio in 2021. The 3,000-square-metre plant is being developed by Rester Oy, which recycles companies' end-of-life textiles and industrial waste materials. LSJH, which processes households’ end-of-life textiles on its production line, will hire part of the plant.

Outi Luukko, Rester Oy’s board chair, says, “The processing plant will begin a new era of textile circular economy in Finland. As industry pioneers, we are launching a system change in Scandinavia. The transition of the textile industry from a linear model to a circular economy is essential, as virgin materials cannot sustain the current structure of the textile industry. And why should it, when there is so much recyclable material available?”

From the perspective of Rester Oy’s main owner, work clothing supplier Touchpoint, the circular economy plant not only represents resource efficiency, but is also necessary from the perspective of the entire life cycle of a responsible work clothing collection.

Luukko adds, “Finding a local solution to a global problem is a huge leap in the right direction and raises Finland's profile as a pioneer of circular economy."

The future plant will be able to process 12,000 tonnes of end-of-life textiles annually, which represents about 10% of Finland’s textile waste. Both production lines produce recycled fibre, which can be used for various industrial applications, including yarn and fabric, insulating materials for construction and shipping industries, acoustic panels, composites, non-woven and filter materials, and other technical textiles, such as geo-textiles.

LSJH is piloting a full-scale refinement plant

LSJH has launched a pilot production line for processing households' end-of-life textiles. Unfortunately, consumers' end-of-life textiles are heterogeneous, making them a challenging raw material for further processing. Before processing, the textiles are sorted by material into various fibre classes using optical identification technology developed by LSJH and its partners. This ensures the quality of the raw material and the resulting fibre products.

Jukka Heikkilä, managing director for Lounais-Suomen Jätehuolto, explains: “On the basis of the experiences gathered from the pilot project, Lounais-Suomen Jätehuolto is preparing a full-scale refinement plant in the Turku region. As soon as 2023, the plant will process Finnish households' end-of-life textiles. The project involves all waste treatment plants owned by Finnish municipalities.”

Paimio has ambitious goals for circular economy companies

Rester’s initiative aims to create a circular economy cluster in Paimio that combines the processing and reuse of end-of-life textile fibres. Paimion Kehitys Oy, which is owned by the City of Paimio and the local association of enterprises, supports the development of circular economy companies in Paimio.

Mika Ingi, managing director for Paimion Kehitys Oy, says, “We want to step out of our traditional municipal role and create significant added value for everyone taking part. That is why we are involved in the development of a new modern service model based on ecosystem thinking. We are piloting the textile cluster, followed in the coming years by clusters focusing on plastic, construction, and energy. The aim of our service is to support and help develop new profitable business by bringing circular economy companies and their potential customers to innovate together."

The foundation stone of the processing plant was laid today (18 August 2020). The processing plant will begin operations in February 2021.
