From the Sector

• Sustainable infrastructure solutions, road safety and health protection

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

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

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

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

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

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

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

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

Working alongside a leading Thai university and a medical device OEM, Cobra created a rapid and cost effective series production process for a lightweight carbon fibre prosthetic foot. In another example of lightweight composites creating major quality of life improvements, Cobra has also designed and manufactured a carbon and glass fibre prepreg foot support for Elysium Industries.

• Hypetex® to Showcase Coloured Carbon and Flax Fibre Solutions
• Hypetex, London, April 20 2022, Booth R52, Hall 6

Hypetex, the market leaders in colouring carbon and natural fibre materials, will demonstrate both the processing and sustainability benefits of its patented colourisation technology when it exhibits for the first time at JEC World 2022.

Exhibiting as part of the Composites UK stand (Booth R52), Hypetex will display its portfolio of uniquely coloured carbon fibre materials including 3K woven styles, ultra-lightweight spread tow fabrics, UD, and 3D materials. Hypetex will also present details of its latest eco-friendly coloured flax materials  which combine sustainably grown natural flax with sustainable colouring technologies. Hypetex patented colouring technology, available in an extensive palette of standard and bespoke colours and shades, can be applied to traditional woven fabric constructions, non-woven UDs, spread tow and bespoke fabric designs. The technology replaces a traditional coloured painted finish, providing an exceptional depth of colour to any composite part, improving thermal conductivity and reducing heat absorption ,whilst reducing the overall weight and processing time with no compromise to the mechanical performance of the composite structure.

By removing the need for painting, and the associated preparation steps, Hypetex technology provides manufacturers with a repeatable straight out of the mould coloured finish, that is not only easy to integrate into all composite processes, but also takes additional materials, consumables, and process time out of the component cost. As part of its continued commitment to leading the drive for more sustainable composite solutions, and its focus on improvements based on the ESG framework. Hypetex will also display its new range of coloured flax fibre textiles. The advanced colouring technology used protects the natural flax fibres throughout the high temperature processes required for composite production, avoiding burning or any discolouration issues common to natural fibres. In addition, Hypetex colouring solution is an ecofriendly sustainable alternative to traditional dyeing processes which are a significant cause of global water pollution.

The Hypetex team will be on hand throughout the show to provide additional details on Hypetex materials and their integration into the manufacturing process. Visitors to the Hypetex stand will be able see Hypetex carbon and flax products in raw fabric, and how its unique colour palette translates into the most distinctive finished moulded components. Hypetex partners SHD Composites, Textreme, Sigmatex and Angeloni will also have materials and components on display at JEC World 2022, including sporting equipment such as racquets, sticks, and skateboards, which highlight the massive range of processing options and potential applications for this novel technology. One such application, the adidas Kromaskin field hockey stick, with a unique Hypetex coloured Textreme spread tow carbon finish, will also be part of the JEC Innovation Planets feature.

High-performance yarns now offer almost unlimited possibilities for replacing traditional raw materials in a vast range of technical applications. Often tailor-made, these filament yarns go way beyond the conventional idea of ‘textiles’ – finding new uses in sectors such as automotive, aviation, maritime, medical and construction, among many others.

Technical textiles are everywhere in our daily lives today, even if we may not always realize it. Some are in more obviously textile products, from sewing threads to artificial turf. But then, take cars as an example: modern vehicles are stuffed with parts made from sophisticated yarns. It’s common for producers of automotive parts now to send template material and requirement lists to Swiss Textile Machinery members, trusting their expertise and experience. Members operate development and testing centers with latest machine installations, where their experts devise customized solutions, as well as calling on the pure innovative spirit which is part of their DNA.

At the extremes
Technology drives applications beyond our current imagining in the case of Heberlein air splicers. Developed for a wide range of uses with high-strength technical fibers, they have no problems splicing aramid fibers up to 16’100 dtex, carbon up to 30’000 dtex, Dyneema up to 5’500 dtex, and glass up to 4’800 tex. Using compressed air, the splicers produce a tear-resistant, homogeneous splice of material without interfering knots.

Retech has the technology to achieve specifications for filament yarns, drawing and stretching fibers to perfection. Top heated godet rolls – many customized – are developed for high-performance fibers. Temperatures up to 400 °C can be achieved. Combining the right settings and wide speed ranges for each specific process results in unique end-products.

Fabric producers of high-end applications must avoid any quality risk. Yarn producers are well aware of this responsibility, so they use precision package winders for technical yarns, developed by Rieter’s subsidiary SSM. Taking yarns from ring twisting bobbins, its specialist finish winders can produce coarse-count technical yarns up to 50’000 dtex, offering a new level of flexibility and winding quality.

Lifestyle essentials
At first glance, motorists might fail to notice many of the technical yarns ‘hidden’ inside their cars. These products have functions such as providing stability with hardly any weight, or absorbing tensile forces at defined elongation. This kind of controlled elongation behaviour, for example, arises from the choice of textile material and the special construction of the yarns used.

Such specifications make twisting and cabling machines essential for the automotive industry. Saurer offers machines for the production of technical yarns made from a variety of feed materials in a very wide yarn count range. They are needed for vehicle products such as tire carcasses, toothed engine belts, seat belts, airbags and lorry tarpaulins.

Technical yarns also play a surprising role in our mobile devices. Tapping, scrolling and swiping are second nature for billions, with our phones and a plethora of other lifestyle essentials. Yet, how many people would know that the touch-sensitivity we take for granted on these screens is largely made possible by twisted glass fibers. Bräcker, part of Rieter’s components business, offers a selection of vertical sinter metal rings and nylon travelers for glass fiber twisting, so that mills can achieve high levels of productivity and quality.

Future unlimited
Automotive and communication technology are already important industries for Swiss Textile Machinery members, along with well-known technical textiles markets in sectors such as medical, transport and construction. Smart-wear is already noted as a field with significant potential. Naturally, members are constantly investigating other possibilities. Swiss textile machinery is already applied in energy (batteries), and plastics.

The Swiss Textile Machinery Pavilion will be at the Techtextil exhibition in Frankfurt, Germany, taking place from 21 to 24 June 2022.

In 2021, nonwovens production in Greater Europe increased in volume by 2.0% to reach 3,120,967 tonnes (and 87.6 billion square metres).

EDANA, the international Association serving the nonwovens and related industries today released its statistics on Nonwovens Production and Deliveries for 2021. Following the impressive growth recorded in 2020, the updated figures for Greater Europe (incl. Western and Eastern Europe countries, Turkey, Belarus, Russia and Ukraine) highlight again the ability of the European industry to innovate and to invest in order to meet the challenges of the pandemic crisis.

In 2021, nonwovens production in Greater Europe increased in volume by 2.0% to reach 3,120,967 tonnes (and 87.6 billion square metres). Since 2019, the European output increased by nearly 9%.

Jacques Prigneaux, EDANA’s Market Analysis and Economic Affairs Director commented “This 2% average growth is in line with European forecasts disclosed in October 2021 in our Global Nonwoven Markets 2020-2025 report. In 2021, significant growth areas for nonwovens were recorded in building construction (+17.4%), agriculture (+11.3%), electronic materials (+10.1%) and air filtration (+9.1%). Countering this, a further decline of -1% was recorded in automotive interior applications. In some market segments, a comparison with the pre-COVID situation is probably more relevant. This is particularly true in hygiene, medical and wipes nonwovens, which were almost flat or slightly decreasing compared to the level reached in 2020, but still much higher than in 2019”.

He added: “Looking at the different production processes of nonwovens, various trends were observed in 2021. The production of fiber-based materials, including Drylaid, Wetlaid, and Airlaid technologies, recorded divergent growth rates (respectively +2.4%, +1.1% and -4.8%), and spunmelt nonwovens recorded a growth rate of +3.1%. In Drylaid, the highest growth in tonnes was observed in needlepunched, with a 6.4% increase. The production of drylaid-hydroentangled, which peaked in 2020, was at the same level a year later”.

The Trevira CS brand was showcased on the German Pavilion at the BIG Show Oman, an international exhibition for building materials, construction equipment, and interior design, in Muscat, Oman. This year, BIG Show, which is part of Oman Design & Build Week, was held from March 14-16.

Trevira CS has been part of BIG Show for years, as it is an important meeting point for the exhibiting companies with interior designers, construction companies, and project managers. Important authorities from the Middle East as well as major hotel brands were present again this year. In the Middle East, important tenders for major projects are due this year. The main focus of the trade show will be on the hotel & catering and hospital & care sectors, for which Trevira CS fabrics are of great interest because they meet the safety requirements that are usually required by law.

Trevira CS presented its extended brand concept that offers customers even more flexibility and also addresses sustainability. Building on to the high brand quality and performance, the recently introduced brands Trevira CS flexand Trevira CS eco offer properties and functions tailored to specific requirements. Furthermore, the Trevira CS Bioactive brand compliments the range, combining flame retardancy with antimicrobial properties. Fabrics bearing this brand meet the requirements for preventive fire protection and increased cleanliness.This brand concept is very well received by Trevira's customers. Many new flame retardant fabric developments embracing one of the Trevira CS brands were on display at BIG Show.

• Project delivered on schedule and at budget after two and a half years of construction despite challenges arising from a global pandemic
• New state-of-the-art lyocell plant with a capacity of 100,000 tons will help serve the growing demand for sustainably produced fibers
• Important milestone towards a carbon-free future has been set

The Lenzing Group is pleased to announce the completion of its key lyocell expansion project in Thailand. The new plant, one of the largest of its kind in the world with a nameplate capacity of 100,000 tons per year, started production on schedule and will help to even better meet the increasing customer demand for TENCEL™ branded lyocell fibers. For Lenzing, the project also represents an important step towards strengthening its leadership position in the specialty fiber market and into a carbon-free future.

The construction of the plant located at Industrial Park 304 in Prachinburi, around 150 kilometers northeast of Bangkok, started in the second half of 2019 and proceeded largely according to plan, despite the challenges arising from the COVID-19 pandemic. The recruiting and onboarding of new employees has been successful. Investments (CAPEX) amounted to approx. EUR 400 mn.

“The demand for our wood-based, biodegradable specialty fibers under the TENCEL™, LENZING™ ECOVERO™ and VEOCEL™ brands is growing very well. In Asia in particular, we see huge growth potential for our brands based on sustainable innovation. With the production start of the lyocell plant in Thailand, Lenzing reached an important milestone in its growth journey, supporting our ambitious goal to make the textile and nonwoven industries more sustainable”, said Robert van de Kerkhof, Member of the Managing Board.

In 2019, Lenzing made a strategic commitment to reducing its greenhouse gas emissions per ton of product by 50 percent by 2030. The target is to be climate-neutral by 2050. Due to the established infrastructure, the site in Thailand can be supplied with sustainable biogenic energy and contribute significantly to climate protection.

Together with the key project in Brazil and the substantial investments at the existing sites in Asia, Lenzing is currently implementing the largest investment program in its corporate history (with more than approx. EUR 1.5 bn). Lenzing will continue to drive the execution of its strategic projects, which are to make a significant contri-bution to earnings from 2022.

Sicomin supported the build of Dubai’s Museum of the Future and supplied its bio-based intumescent gelcoat as well as fire-retardant laminating resins for the production of over 200 double curved panels making up the interior of the Museum’s entrance lobby.

The Museum of the Future, a new addition to Dubai’s skyline by architects Killa Design, engineers Buro Happold and contractor BAM International, opened last week on 22nd February 2022 and features a large percentage of composite materials in the interior construction.

Advanced Fiberglass Industries (AFI) manufactured 230 double curved interior panels, a double-helix DNA structure staircase that scales the full seven levels of the museum and 228 GRP oval shaped light structures for the museums car parking area.

Adaptable mould technology from Danish company Adapa, was introduced by Advanced Fiberglass Industries, Dubai (AFI) to ensure that the interior panels could be delivered in line with the project schedule. As well as allowing each panel shape to be rapidly configured without the machining of traditional moulds, the adaptive mould technology massively reduced waste generated in the moulding process, contributing to the building’s low carbon LEED platinum credentials.

With a challenging structural and fire safety specification defined, Sicomin’s bio-based SGi128 intumescent gelcoat and SR1122 fire retardant laminating epoxy were chosen for the panels, an additional advantage being that in addition to high fire properties, SGi 128 is also formulated with over 30% carbon from renewable sources, reducing the final carbon footprint significantly.  

Sicomin worked alongside the panel manufacturer, providing technical support for the fire test panels and the initial Adapa moulding trials.

The annual highlight of the industry is the International Conference on Cellulose Fibres in Cologne, where the latest innovations were showcased: new cellulose fibre technologies for various feedstocks and a wide range of hygiene and textile products as well as alternatives to plastics and carbon fibre for lightweight constructions.

This year, for the first time, there were 230 participants from 27 countries. About 60 were able to attend on site – with strict Corona safety measures – while the others were able to attend online and participate in questions and discussions.

The conference gave deep insights into the promising future of cellulose fibres, which fit perfectly into the current trends of circular economy, recycling and sustainable carbon cycles.

An important focus at the conference was alternative sources of cellulose. The increasing demand for cellulose fibres cannot be met in the long run with wood and used textiles alone. At the conference, a variety of agricultural by-products and biogenic waste were presented in presentations and panel discussions, such as orange and banana peels, grain and hemp straw. Much of this is high-volume and has not been put to high-value use so far. Exciting opportunities for the future cellulose fibre industry.

Innovation Award
