From the Sector

Smart textiles have the potential to revolutionise healthcare. In his doctoral thesis in textile technology at the University of Borås, Emanuel Gunnarsson presents unique solutions to the bottleneck that has long inhibited the market.

With an ageing population, increasing demands are being placed on healthcare and smart textiles can offer a solution where only imagination sets limits. “The long-term goal of most smart textiles is for them to be so easy to use that the user doesn't think of them as anything more than regular garments. No special procedure should be needed to use them. If we succeed in that, we won't burden healthcare by having healthcare personnel administer vital parameter monitoring such as blood pressure and pulse, as the user can handle it themselves,” said Emanuel Gunnarsson.

In his work, he has investigated how a t-shirt for measuring heart rhythm and movement patterns, and garments for electrostimulation, can be produced in a single step. This involves the connection between the contact surfaces (electrodes), the insulated conductive paths between the electrode and the contact point, and the electrical measuring equipment required.

“This, as far as we know, has never been described before. We are completely convinced that this is the solution to a significant bottleneck when it comes to getting the smart textile market going in earnest,” said Emanuel Gunnarsson.

His work has resulted in two different simple ways to produce smart textiles. He demonstrates that sensors can be integrated using standard textile manufacturing methods. The research also includes criticism of some of the methods used to measure the functionality of smart textiles, and advice on how to do it better instead.

“The next natural step will be to see how these garments cope with one of the toughest challenges a garment faces, namely washing. Especially as these garments must be worn closest to the skin, they will need to be washed relatively often,” said Emanuel Gunnarsson.

Studies from other universities indicate that the yarns used to measure signals from the body do not withstand many washes, but after a small pilot study, Emanuel Gunnarsson is hopeful of the opposite.

Members of TMAS – the Swedish textile machinery association – will display technologies in alignment with the theme of digitalisation at the forthcoming Techtextil and Texprocess 2024 exhibitions, taking place in Frankfurt from April 23-26th.

Automatic handling
The fully automated and digitised handling solutions for finished garments, home textiles and furniture of Eton Systems, for example, will be demonstrated at Texprocess.

Designed to increase value-added time in production by eliminating manual transportation and minimising handling, the individually addressable product carriers are fully managed and controlled by the latest ETONingenious™ software. This web based real-time data collection and information system continuously accumulates, processes and makes all production information instantly available to supervisors, quality control personnel and management.

Bespoke seams
Svegea will demonstrate its EC 300-XS colarette technology, which is used by garment manufacturers around the world for the production of tubular apparel components such as cuff and neck tapes and other seam reinforcements.

The EC 300-XS collarette cutter on show in Frankfurt is equipped with the latest E-Drive II system providing the operator with a very user-friendly touchscreen, providing full control of the cutting process. An accompanying FA 350 fully automatic roll slitting machine will also be demonstrated.

Digital finishing
At Techtextil meanwhile, Baldwin Technology Co. will provide full details of how its highly digitised TexCoat G4 non-contact spray technology for textile finishing and remoistening not only reduces water, chemicals and energy consumption, but also provides the flexibility to adapt to customer requirements in terms of single and double-sided finishing applications.

TexCoat G4 can reduce water consumption and chemical usage by as much as 50% compared to traditional padding application processes.

Yarn tension
Celebrating its 60th anniversary this year, Eltex will display the latest Eltex EyETM system for the continuous monitoring of yarn tension on warp beams.

The Eltex EyETM eliminates problems when warping, and also in subsequent weaving or tufting processes, monitoring the yarn tension on all positions in real-time and enabling a minimum and maximum allowable tension value it be set. If any yarn’s tension falls outside these values the operator can be warned or the machine stopped.

The Eltex ACT and ACT-R units meanwhile go beyond yarn tension monitoring to actually control yarn tension. This extends the application range greatly. The plug and play system automatically compensates for any differences in yarn tension that arise, for example from irregularities in yarn packages.

Accumulated know-how
Vandewiele Sweden AB benefits from all of the synergies and accumulated know-how of Vandewiele Group, supplying weft yarn feeding and tension control units for weaving looms to the majority of weaving machine manufacturers. It also retrofits its latest technologies to working mills to enable instant benefits in terms of productivity and control.

The company will present its latest X4 yarn feeders with integrated accessory displays (TED) as a new standard, as well as launching its own e-commerce platform – iroonline.com.

The TED function enables weft tension settings to be transferred from one machine to another, enabling a fast start-up the next time the same article is woven. The position of the S-Flex Tensioner is constantly monitored by an internal sensor – even if adjustment is made during power off.

X4 feeders are also available with integrated active tension control (ATC-W) as an option. With the ATC-W active tension control, the required tension is easily set and monitored on the integrated display. Once set, the system constantly regulates itself, ensuring consistent yarn tension during the weaving process which is constantly and accurately measured by the ATC sensor unit, sending a signal to the ATC operator unit resulting in consistently stable yarn tension at the required level.

On display at Sculpture by the Sea, the land art event that brings the Sydney coastline to life every year, is “Seabilia”, Elena Redaelli’s latest work created using waste fabric from Sitip’s production processes. A creation that draws attention to the environment and its fragility in the face of human activity, “Seabilia” is a reminder of how precious yet delicate this balance is, and how humans must become mindful of their actions before the effects end up being completely irreversible.

Sitip's commitment to environmental sustainability struck a chord with Elena Redaelli, and a meeting between the Bergamo-based textile company and the artist from Erba, Italy, led to “Seabilia”, a work that will be displayed as part of Sculpture by the Sea on Tamarama Beach near Bondi in Sydney.

It’s one of the most popular events to take place in this corner of Australia, attracting half a million visitors who flock to these Aussie beaches to admire more than one hundred works created by artists from all over the world.

Held since 1997, this event captures the imagination of its visitors for three weeks each austral spring and, thanks to the vast area it covers, has earned the title of largest annual sculpture exhibition in the world.

The 2023 edition, scheduled to take place from 20 October to 6 November, will feature Elena Redaelli's work created using waste Native-Cosmopolitan Kyoto fabric which, having failed the company's quality control tests, was donated to the artist.

A post-consumer recycled circular knit fabric composed of 89% recycled polyester (PLR), 11% elastane (EA), and weighing 240 grams, the Native-Cosmopolitan Kyoto is made from recycled yarns derived from plastic waste that’s been recovered from the environment, particularly from the sea and from recycling centres. The fabric is Bluesign, GRS (Global Recycled Standard) and OEKO-TEX certified, attesting to Sitip's commitment to environmental responsibility and protection.

During the process, the artist hand-cut the waste fabric and crocheted the pieces together using recycled cotton and other types of thread.

In the creative mind of the artist, the genesis of “Seabilia” arose from deep in the ocean where tiny creatures inhabit the darkest, least explored parts of the planet. A place where the rhythm of life for the inhabitants is marked by silence and obscurity, while waves and tides agitate the surface above. The life of the ocean, such a vast and imposing environment, is impacted every single day by human activity, slowly weakening its delicate balance. “Seabilia” is intended to act as a reminder of how precious yet extremely fragile this balance is, and how humans must become more aware of the consequences of their actions before it’s too late and such a vital asset is lost forever.

“Following Emersione, a work that was exhibited at the Ex Ateneo in Bergamo during Fiber Storming, a textile art exhibition organised by ArteMorbida Textile Arts Magazine and curated by Barbara Pavan, Seabilia is the second art project where I’ve had the opportunity to utilise SITIP's fabrics. – explains the artist, Elena Redaelli. As it was going to be displayed on the rocks at Tamarama Beach, my installation needed a durable, elastic fabric with structural characteristics capable of withstanding ocean winds and sudden changes in weather. Using waste Native-Cosmopolitan Kyoto fabric was the obvious choice, not just because of its very high quality, but also, and more importantly, because it’s made from recycled yarns derived from plastic waste that’s been recovered from the environment, often even from the sea itself. The different textures and shades of white enabled me to create a varied work that, despite the almost monochromatic tones, conjures a diverse range of tactile sensations. The biomorphic modular composition evokes skeletons of sea creatures that appear to have been deposited onto the rocks by a wave and left there to wither in the blazing Australian sun.”

•    First production supercar created with Hypetex coloured carbon fibre
•    Paint-replacement technology reduces weight to enhance performance

British car manufacturer Briggs Automotive Company (BAC) has created a unique Hypetex coloured carbon fibre version of its Mono R, reducing the weight by removing the need for paint.  

The original BAC Mono R was created to be lighter and more powerful than the standard model, with 343bhp and 555kg total weight, equating to a power-to-weight ratio of 618bhp-per-tonne. By removing the need for paint coatings in this version, the net weight of the exterior is reduced compared to a painted shell, resulting in a further improved overall performance.

The car’s body was created using Hypetex’s titanium carbon fibre twill, and finished with a crystalized lacquer, offering a unique aesthetic finish. The ultra-lightweight supercar can accelerate from zero to 60mph in less than 2.5 seconds.  

Hypetex’s paint-replacement technology retains the visible weave, allowing for a bold design and a choice of colours without technical compromises, perfectly aligning with BAC’s initiatives to maximise performance whilst creating bespoke supercars. Paint generally adds 138 grams per metre squared, whereas Hypetex adds just 17 grams for the same area, offering an 8x weight saving.
This bespoke version of BAC’s single-seater Mono R was subject to BAC’s renowned BAC Bespoke programme, which ensures that no two Monos are the same. The client, a US-based collector, worked with BAC’s design team to design the car to their personal taste.   

Born out of Formula 1 technology, Hypetex offers manufacturers sustainable aesthetic materials with technical and efficiency benefits. This collaboration is an all-British success story, with the Hypetex carbon fibre body built by Formaplex, a leading UK-based manufacturing company who manufacture lightweight engineered solutions for top tier customers in Automotive, Aerospace and Defence markets. BAC’s supply chain is 95% UK-based.  

Hypetex continues to expand its growing portfolio of the use of coloured carbon fibre to add personalisation to the automotive field, with its material recently featured on the 2024 Ford Mustang Dark Horse.  

OCSiAl, a leader in graphene nanotube technologies, has been granted a construction permit for a nanotube production facility near Belgrade, Serbia. The new nanotube synthesis plant will be launched in 2024 and will have an initial annual capacity of 60 tonnes of graphene nanotubes. Over the next two years, the capacity of this plant will be increased to 120 tonnes per year. “The project will facilitate logistics and lower supply chain costs. European-produced nanotubes and nanotube derivatives will be primarily supplied to our customers in central and western Europe, North America, and Asia,” said OCSiAl Group Senior Vice President Gregory Gurevich.
 
In addition to synthesizing nanotubes, the facility will manufacture nanotube suspensions for lithium-ion battery manufacturers in Europe, the US, and Asia – enough to enhance the performance of more than 1 mln electric cars with an average battery capacity of 75 kWh per car. OCSiAl nanotubes create long and robust electrical networks between active material particles, improving key battery characteristics, including cycle life, lower DCR, C-rate performance, and cohesion between active battery material particles, making the battery electrodes more durable. Graphene nanotubes unlock new battery technologies, including high-silicon content anodes, thick LFP cathodes, fast-charging graphite anodes, and more. They can be applied in both conventional and emerging battery tech, such as a dry battery electrode coating process, and solid-state batteries.
 
As well as synthesizing nanotubes and producing suspensions, OCSiAl project includes manufacturing of nanotube concentrates for high-performance polymers. The project has passed environmental impact assessment and it is 100% powered by green energy. It enjoys support from Serbian municipal and national governments. The plant is planned to be certified in accordance with ISO 9001, ISO 14001, and ISO 45001, and to be compliant with the IATF 16949 automotive industry standard. The project will create more than 200 job opportunities for engineers, scientists, managers, operators, and administrative staff.
 
Currently, OCSiAl has an extensive manufacturing system of nanotube-based products in the regions of highest market demand, such as China, Japan, Sri Lanka, Brazil, Malaysia, and other countries. The Serbia nanotube hub will operate in conjunction with the company’s operational R&D center and planned graphene nanotube synthesis facility in Luxembourg.

Beaulieu International Group will turn the spotlight on geotextile products with sustainability benefits to support progress in resilient civil engineering projects at the 12^th ICG Rome from 18^th -21^st September 2023, presenting options to target fossil carbon reduction by choosing PP-based staple fibres or woven geotextiles that are among the lowest in carbon footprint for geosynthetics.

For manufacturers of nonwoven geotextiles, Beaulieu Fibres International (BFI) offers PP fibres with > 25% carbon footprint reduction compared to the European standard PP fibres, generating 1.48 kg CO₂/kg PP fibres. A step further is to accelerate the replacement of fossil carbon in engineered fibre applications by choosing its ISCC Plus certified bio-attributed MONO-PP with a negative carbon footprint.

For construction projects, nonwoven geotextiles made with high-tenacity HT8 fibres are proven to secure a longer service lifetime and reduce the environmental impact, as they offer high mechanical performance at a reduced weight.

Beaulieu Technical Textiles' (BTT) woven geotextiles provide a wide range of functions, including separation, filtration, reinforcement and erosion control, and are among the most sustainable in the industry. Depending on weight, the carbon footprint of its woven geotextiles (m²) ranges between 0.37 and 1.40 kg CO₂ eq./m². They also minimize the use of natural resources for more sustainable infrastructure development. Case studies such as at the Ostend-Bruges airport highlight significant CO2 reduction on the jobsite by replacing the transport of 960 trucks of gravel with 3 trucks of woven geotextiles, and by extending the runway’s life span.

The ICG launch of its new line Terralys MF woven filtration geotextiles with monofilament boosts the performance of a common solution in building layers that require high water flow rates. High-tenacity extruded polypropylene tapes and monofilaments are interwoven to form dimensionally stable and highly permeable geotextiles. These new filtration geotextiles provide greater resistance to dirt and biological clogging. They allow water to travel freely while reducing soil erosion when employed as a separation and stabilizing layer.

As of September 2023, all PP staple fibres and woven geotextiles will have Environmental Product Declarations (EPD) based on LCAs. Each EPD is an essential tool for communicating and reporting on the sustainability performance and helps carbon-conscious customers in their purchasing and decision making. Registered EPDs are globally recognized, publicly available and free to download through EPD Libraries.

Freudenberg Performance Materials (Freudenberg) is launching its latest innovation Evolon® Ultra Smooth to serve the specific packaging needs of technical industries.

Evolon® Ultra Smooth fabrics are low-linting, strong and hard-wearing. The new materials are designed for industrial parts and components which require low-friction, sliding behavior during the part packing and handling procedures. Furthermore, they are durably hydrophobic and available in different weights. The reusable textile containers made of Evolon® Ultra Smooth can be used in various industries to pack and transport even very heavy and sensitive parts without damage.

The Evolon® Ultra Smooth materials have a point-sealed patterned white surface which is very different from the standard Evolon® packaging textiles and which makes them easily identifiable.  

Evolon® Ultra Smooth materials protect the surfaces of industrial and automotive parts by avoiding micro-scratches or lint contamination. By using Evolon® Ultra Smooth reusable packaging to transport parts with highly-sensitive surfaces, customers reduce the number of damaged parts and the reject rate. The innovation is available worldwide. As Evolon® Ultra Smooth is 100% made in Europe, European customers benefit from even greater flexibility in the supply chain and quick go-to-market.

• Flame Retardancy for Composites Applications in the Transport Sector

On 10-11 May 2023, the AVK - Industrievereinigung Verstärkte Kunststoffe e. V. in cooperation with the FGK - Forschungsgesellschaft Kunststoffe e.V. in Berlin organised for the first time an international, English-language conference on flame retardancy.

In 18 compact lectures, more than 20 experts informed nearly 80 participants about new developments, requirements and innovations regarding specific flame retardant properties of components made of fibre-reinforced plastics/composites for the transport sector.

Among others, there were presentations by industry representatives from Saertex, BÜFA, Clariant, Diehl Aviation and Airbus, but also from institutes such as the Fraunhofer Institutes or the Federal Institute for Materials Research and Testing. Presentations on the topics of standardisation, raw materials, automotive or recycling were on the agenda, but also flame retardants for connectors and battery housings for electric vehicles or fire-retardant systems for rail vehicles or fire-retardant CFRP made from recycled CF nonwoven were presented.

By using a high share of recycled content in its Evolon® materials, Freudenberg Performance Materials (Freudenberg) offers technical packaging textiles with a carbon footprint decreased by 35%. An independent LCA study showed additional benefits such as energy resource savings and lower water use. Furthermore, Evolon® fabrics provide sustainability benefits over the packaging entire life cycle thanks to high end performance and durability.

By replacing virgin PET with recycled PET, the cradle-to-gate carbon footprint of Evolon® packaging textile materials decreased by 35%. This is the result of a study by an independent LCA and eco-design consultancy firm, which made a Cradle-to-Gate assessment of several Evolon® products using virgin PET or recycled PET. The study was finalized in 2022 and conducted according to the principles of ISO 14040/ ISO 14044 standards, following the recommendations of the Product Environmental Footprint and the Circular Footprint Formula.

Evolon® microfilament textiles have a small carbon footprint because their manufacturing process uses low CO2 energy sources. The fabrics are lightweight and can be reused throughout entire production programs, e.g. of a car model when it is about the automotive industry. Furthermore, the new Evolon® RE fabrics contain up to 85% of recycled PET which is produced in-house out of post-consumer PET bottles.

Evolon® textiles are suitable for reusable technical packaging, which eliminate the use of thousands of disposable packaging materials. Evolon® fabrics offer scratch-free, lint-free, high-end surface protection for molded plastic parts, painted parts and other sensitive industrial and automotive parts during transport. This contributes to lower the scrap rate of parts and provide both financial and ecological benefits. By using Evolon® reusable packaging to transport highly-sensitive parts, customers can increase their efficiency and save resources.

• Focus on the guiding principle of "textile intelligence" and sustainability

Long before sustainability became a trend in the textile industry, Schoeller Textil AG, which has been innovating technical fabrics and smart textile finishing technologies for more than 150 years, made it its mission to develop textile innovations in harmony with nature. Now the company is undergoing an extensive rebranding, whilst unveiling its strong brand foundation in the process. The result embodies the newly defined guiding principle of “Textile Intelligence” - the development and successful implementation of innovative textiles and intelligent textile technologies.

Innovations in the textile industry must meet requirements on several levels – offering both new and optimized solutions to sociological, ecological, and economic challenges of our time. Creating this holistic added value is firmly rooted in the Schoeller brand origin and is still the top priority in textile product development today. The brand essence has thus remained the same, but it has been embodied anew.

“At the beginning of the rebranding process, it was clear to us we had to root ourselves in (Swiss) tradition in order to fully realize Schoeller’s entire brand potential and successfully explore new, digital paths,” said Antonio Gatti Balsarri, Schoeller chief commercial officer.

“The goal of the rebranding is to communicate our traditional brand values in a completely new brand presence. The result was a sharpened brand profile, a clear brand strategy and tonality, as well as a clean, modern corporate design. We will specifically address our sustainability commitment through the expansion of digital touchpoints, their cross-media use, and an increased online presence. Simplified, straightforward, sustainable - in accordance with our greatest source of inspiration: nature.”

Transparency and Sustainability
Paramount to Schoeller’s corporate identity is the full disclosure of brand principles and transparency around all business divisions. A simplified logo design was established by reducing logo elements and colors for a modern look and feel that can be produced in a much more resource-efficient manner. Schoeller’s new brand mantra of “Textile Intelligence” speaks to its company mission of more than 150 years.

Schoeller has been a bluesign system partner from the very beginning and uses the Higg Facility Environmental Module (FEM) to assess sustainable performance. In addition to environmentally-friendly manufacturing processes and careful material selection, the highest quality and sustainability standards in production also mean guaranteeing fair working conditions. Schoeller follows a Code of Conduct that guarantees transparent production chains, environmental protection, and fair working conditions.

“Zero Textile Waste” becomes a targeted brand strategy. While the production of textiles and textile technologies is continuously being optimized to preserve resources, the manufacturing processes are often costly and complex. To this end, Schoeller offers new approaches to efforts around Zero Waste in the industry. Its new online shop, “Schoeller re-Fabric” sells textile remnants from production directly to designers and smaller productions to increase its overall production volume efficiency and avoid textile waste.
