From the Sector

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.

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".

The textile machinery industry is eagerly awaiting the start of the virtual trade show "Innovate Textile & Apparel". What and how will the more than 160 exhibitors present themselves virtually? How will the approximately 10,000 registered visitors accept the digital offer? WTIN is breaking new ground as organizer with this platform. But one thing is already certain: From 15 to 30 October 2020, they will bring the textile machinery industry a little closer together again in the Corona Pandemic. Oerlikon invites all visitors to take a look into the future of manmade fibers production and get to know the comprehensive range of products and services.

"Reconnecting innovation in the textile & apparel value chain" is the motto of WTIN's virtual trade show. And Oerlikon intends to more than live up to this motto. With more than 50 active experts from sales, customer service and technology as well as partners from its international network of representatives, the Manmade Fibers segment of the Swiss Oerlikon Group will try to be represented around the clock. "It is an interesting experiment for all of us and we would like to see it succeed," explains André Wissenberg, Head of Marketing, Corporate Communications and Public Affairs. "Our aim is to meet our existing customers again, make new contacts and see 'old friends' from the industry. We have prepared an attractive digital offer for them all. Those of you who missed our roller coaster ride in Barcelona last year can now enjoy the journey through time in peace and quiet from your home office on your digital tour of the fair. And, there are no more waiting times either," promises Wissenberg.

Factory know-how from a single source
From Melt to Yarn, Fibers and Nonwovens. From the polycondensation and the processing of PTA and MEG as well as the extrusion of, for example, recycled polyester chips all the way through to hundreds of thousands of packaged and stored or directly-delivered textured bobbins for a market within the textile industry worth billions. From the planning and construction of highly complex production plants to the engineering of large-scale plant projects and competent customer services. This business model runs like a red thread through the self-conception of the Manmade Fibers segment of the Swiss Oerlikon Group. The right partner, especially – but not exclusively – for newcomers to the textile industry. "With us they get everything they need for a successful business: Factory know-how from a single source. And that's what we would like to show our visitors at our virtual trade fair booth," says Wissenberg.

Sustainability and environmental responsibility are important developments for the current design of productions and products. In order to obtain a comprehensive evaluation of the potential of bio-based composites, the AZL, together with an industry consortium, is investigating the market potential, future applications and relevant technologies for bio-based composite materials. The 5-month market and technology study will start on October 22nd, 2020 and is open to interested companies. Companies such as REHAU, an Automotive Tier 1, Asahi Kasei, Johns Manville, Mahr Metering Systems and several material manufacturers are participating in the study.

Bio-plastics are well established in industry, especially in packaging applications. The market for biopolymers is expected to grow from USD 10.5 billion in 2020 to USD 27.9 billion in 2025. At the same time, bio-based raw materials, such as natural fibers, are available on the market in a cost-effective manner. Composites with wood or natural fiber content are also increasingly used in products.

Dr. Michael Emonts, Managing Partner of AZL: "Together with our partner companies we want to identify hidden business potential for composites with bio-based materials. To do so, we will reapply our established approach for market and technology studies: Based on a detailed market analysis, we will dive deep into the technological evaluation of technologies, applications and business cases.”

Based on a detailed market segmentation, AZL's technology experts analyze the various market segments in terms of their size, growth potential, relevant players and existing and future applications. For the identified applications, the participants in the study will receive detailed insight into the respective technical and legal requirements as well as an overview of value chains, processes and materials. In the following, the strengths and challenges of bio-composites compared to conventional materials are elaborated. The consortium will select the components with the highest potential, for which suitable production scenarios will be developed and analyzed in terms of costs in a business case analysis.

"We are participating in the AZL study to identify and evaluate new product areas with bio-materials. The technological analyses of the AZL studies have already helped us in the past to initiate new developments," says Dr. Steven Schmidt, Director Technology Platforms Materials at REHAU, explaining the motivation for working with the AZL and the industry consortium. "As one of the 50 Sustainability & Climate Leaders, we at REHAU are incorporating environmentally friendly materials into more and more products. Wherever the company is active - from the furniture and construction industries to the automotive industry - REHAU is already developing and manufacturing high-quality products from recycled raw materials. By 2025, REHAU plans to increase its recycling rate across the Group to significantly more than 15 percent and at the same time reduce CO2 emissions by at least 30 percent," adds Dr. Steven Schmidt.

Bio-composites will also be the topic of the upcoming Lightweight TechTalk by AZL on September 29, 2020. Experts from industry and academia will give technology and market insights on sustainability and recycling of composites in 6 presentations. Registration is free of charge at: https://azl-aachen-gmbh.de/termine/recycling-of-composites/.

The kick-off of the project will take place on October 22nd, 2020 in the form of a video conference. Further background information on the project can be found under the following link: https://azl-aachen-gmbh.de/wp-content/uploads/2020/09/2020-251_OP_Bio-Bases_Composites.pdf

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.

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.

Technologies with an excellent environmental performance throughout the entire product life cycle – that is what “Autoneum Pure.” stands for. In future, components that meet the highest standards in terms of sustainability and eco-friendliness can be identified at a glance under this label. This also includes the innovation “Mono-Liner” for wheelhouse outer liners.

As innovation leader in acoustic and thermal management, Autoneum continuously invests in the development and production of resource-saving components that make cars lighter and thus more climate-friendly. In view of an increasing sustainability awareness and the correspondingly greater information needs on environmentally-friendly vehicle components, the Company has now launched Autoneum Pure. The label determines particularly sustainable technologies, thereby guiding car manufacturers in product selection for future models.

Autoneum Pure is based on a comprehensive set of criteria assessing the sustainability performance of a product in all four phases of its life cycle: material procurement, production, use and end of life. For example, components with a high content of recyclable materials or those that achieve significant weight savings compared to comparable standard components qualify for the “Autoneum Pure.” label. Autoneum already offers various multifunctional technologies that meet the high standards for Autoneum Pure products: Ultra-Silent for underbody systems or battery undercovers, Di-Light for carpet systems, Prime-Light and IFP-R2 for inner dashes and floor insulators as well as Hybrid-Acoustics PET for e-motor encapsulations and engine-mounted parts, which was launched in fall 2019.

With Mono-Liner, the latest innovation for wheelhouse outer liners is also included in the Autoneum Pure portfolio. Among other things, the Mono-Liner-based components convince thanks to their lightweight construction, thereby contributing to lower vehicle weight with correspondingly less fuel consumption and emissions. The excellent life cycle assessment is also based on their particularly resource-saving manufacturing: Production cut offs of the components, which consist to a large extent of recycled PET fibers, can be processed into pellets and completely returned to the manufacturing process as fibers. An SUV and a crossover model from a US vehicle manufacturer already benefit from Mono-Liner wheelhouse outer liners.

Anahid Rickmann, Head of Corporate Communications & Responsibility, explains: “With Autoneum Pure we are the first automotive supplier to establish a sustainability label in the field of acoustic and thermal management. Autoneum Pure is part of the Company's Advance Sustainability  Strategy 2025 and sets industry standards in product communication.”

For the sixth time now, Oerlikon Nonwoven will be showcasing market- and customer-oriented solutions for hygiene, medical, filtration and other technical applications at the globally-leading nonwovens trade fair INDEX in Geneva, Switzerland. Between March 31 and April 3, 2020, visitors to the trade fair can convince themselves of the Neumünsterbased systems constructor’s extensive product and process know-how.

Comprehensive spunbond portfolio – always the right solution
Oerlikon Nonwoven meanwhile has a very broad range of spunbond technology products and services. The process for manufacturing geotextiles from polyester or polypropylene has been optimized; it is characterized by high production capacities and yields, with simultaneously low energy consumption for producing benchmark nonwoven products.

For the manufacture of hygiene nonwovens, Oerlikon Nonwoven offers its new QSR (Quality Sized Right) systems. Here, the benefits of the Chinese machine construction partner’s nonwoven formation are integrated into the complete solution. The advantage for nonwovens producers: highly competitive solutions at attractive prices with comparably low investment.

Cost-efficiently manufacturing meltblown nonwovens
New, unique and highly sophisticated filter media can be easily and efficiently manufactured thanks to Oerlikon Nonwoven’s optimized meltblown technology. Whether as a stand-alone system with one or several positions, as ‘plug & produce’ installations for already existing systems or in conjunction with other technologies: the Oerlikon Nonwoven meltblown process already enables the cost-efficient manufacture of meltblown nonwovens with the quality requirements of tomorrow. Ever more producers are choosing the meanwhile extensively tried-and-tested and consistently further-developed Oerlikon Nonwoven meltblown solutions.

Airlaid technology for the nonwovens of tomorrow
Pulp or cellulose fibers as raw material for manufacturing nonwovens are currently virtually unrivaled with regards to sustainability and environmental compatibility. The Oerlikon Nonwoven airlaid process is the ideal solution for processing this raw material into high-end products for a wide range of applications. Today, there is huge demand for manufacturing solutions for high-quality, lightweight airlaid nonwovens with economically attractive production speeds and system throughputs. In this area, the patented Oerlikon Nonwoven formation process – which also permits the homogeneous mixing of the most diverse raw materials, while simultaneously guaranteeing superb evenness and homogeneous fiber laying – is setting standards even for nonwovens with low running meter weights. And the benefits of this technology are also increasingly gaining significance in sustainable recycling applications.

P&G patented PHANTOM technology from Teknoweb Materials
Also being showcased at the trade fair stand is the P&G patented PHANTOM technology from Teknoweb Materials, Oerlikon Nonwoven’s strategic partner for hygiene products and wipes. The PHANTOM technology is released to Teknoweb Materials by P&G in worldwide exclusive license. The PHANTOM technology is the superior dry laid alternative technology for manufacturing wet wipes from pulp and polymer fibers, for example. Compared to conventional, known processes, this technology offers superior performances with cost advantage in much more eco-friendly products. Dispensing with hydroentanglement renders subsequent drying of the material redundant. Targeted process management allows the optimal setting of the relevant product parameters such as softness, tenacity, dirt absorption and liquid absorption.

The Lenzing Group completed the second pilot production plant announced in May 2018 for its innovative filament yarn TENCEL™ Luxe. Construction of the facility at the Lenzing site involving investments of EUR 30 mn could be concluded on schedule and within budget after 20 months of intensive work. The new pilot production line, which was put into operation in the middle of December 2019, gives Lenzing sufficient capacity for commercial programs and further application development.

Innovation in the eco-couture segment
Thanks to TENCEL™ Luxe, Lenzing is able to embed the issue of sustainability in the premium luxury market in combination with superior aesthetics. The properties of the fine filament yarn can be compared to those of silk due to its airy feeling on the skin and the matte finish. At the same time, TENCEL™ Luxe also stands out because of its extensive strength and high level of environmental compatibility. It is perfectly suited for very fine fabrics and as a blending partner for silk, cashmere and wool. “TENCEL™ Luxe opens up new markets for Lenzing and thus contributes to the successful implementation of their sCore TEN corporate strategy.

• Increasing demand for graphite-based automotive solutions
• Strengthening SGL Carbon’s site in Bonn

Over the past three years, SGL Carbon has invested a total of around 25 million euros in the modernization and expansion of its production capacities for specialty graphite automotive components at the Bonn site. The expansion project was completed at the end of last year and was inaugurated today at the site in an official ceremony. Besides the installation of partly new production facilities and a modernized production set-up, construction of a new, 2,000 m2 large hall for the production of the parts was implemented in the course of the expansion.

The background of the expansion is the continuously increasing demand for advanced solutions and products made from graphite in the automotive sector. Due to its durability, high strength, low friction behavior, and high conductivity, the material is suitable for many different automotive applications. Examples include rotors and vanes in vacuum pumps for brake boosters, bearings for exhaust gas management, and sealing rings and bearings for seals in coolant pumps. These solutions include applications for vehicles with conventional combustion engines as well as for e-mobility, thereby making an important contribution to clean driving, higher energy efficiency, and lower emissions.

“Automotive components made from specialty graphite are increasingly becoming the standard in many different applications in the automotive industry. Due to their special properties, they are more and more frequently replacing the materials previously used in pumps and seals, such as plastic and metal. By investing in the modernization and expansion of production in Bonn, we are consolidating our leading position in this market and offering our customers real added value in the close partnership with each other. Through the expansion, we are also strengthening our site in Bonn,” explains Burkhard Straube, President of the business unit Graphite Materials & Systems.
