From the Sector

When textiles are equipped with electronic components, conductive yarns and textile sensors, the application possibilities are almost unlimited. These high-tech textiles are a global growth market. In Stuttgart, manufacturers, users and researchers presented amazing examples of applications in construction, architecture and mobility. The appropriate standards ensure quality and safety.

In keeping with the themes of the event, participants were able to take a look behind the construction fence of the Stuttgart 21 rail project on the first day. After the tour, DITF board member Götz T. Gresser drew parallels with the market for smart textiles. Just like the completion of the underground station, the market potential for smart textiles is developing more slowly than predicted.

One important reason for this is that there is still a lot to be regulated. Standardization was therefore a key topic in the presentations on the second day of the event. Norms and standards create trust among users. They reduce the error rate in design and therefore development costs, helping to bring innovations and new technological developments into use. Kristina Müller from the German Institute for Standardization explained that consistent compliance with standards can reduce error costs in construction, for example, from the current estimated eleven percent to five percent per year. Jan Beringer from the Hohenstein Group used the example of actively illuminated high-visibility clothing to show the hurdles that need to be overcome on the way to standardization.

In addition to high-visibility equipment, workwear offers many opportunities for smart functions. Despite all safety precautions, accidents at work cannot always be avoided, explained Silke Rehm from Adresys. Smart clothing can then automatically make an emergency call and trigger an emergency shutdown of the machine.

There are suitable testing devices for monitoring and quality assurance of materials and textile surfaces. Stefan Fliescher from Textechno presented a device that has so far been exclusively used at the DITF.

The second block of presentations focused on mobility: examples included textile ideas for flight cabins of the future from Diehl Aviation, precise and therefore energy-saving heating systems for vehicles from Köstler and contactless sensor technology from Rotec, which detects when fiber ropes need to be replaced. Erhardt manufactures flexible, customized bodies for commercial vehicles They are particularly suitable for logistics in city centers and are equipped with textile sensors, for example for measuring temperature or determining the optimum load. The textile superstructures not only offer a textile surface for design, they can also communicate with their surroundings. Digital lettering shows when the vehicle is giving way or warns cyclists of blind spots when turning. Modules that are not required can be folded or rolled up to save space.

In the construction and architecture application area, solutions for climate change are in demand. TEC KNIT has developed smart shading systems made from “shape memory” polymer fibers that close or reopen depending on the temperature. Optigrün relies on smart rainwater management for greening buildings. Textile sensor technology ensures that the water is optimally distributed over the surface - digitally controlled according to the weather forecast. Michael Schneider from the Smart Textiles Hub showed how intelligent knitted fabrics installed on flat roofs detect moisture and temperature by contracting or expanding accordingly. This can also prevent damage caused by icing, for example. Christoph Riethmüller from the DITF explained that the actual state of buildings is constantly changing due to events. The charm of smart textiles is that they can adapt to these changes. In this way, it is possible to intervene before negative consequences become noticeable. This saves a lot of energy. For example, the targeted heating of walls depending on the relative humidity prevents the occurrence of mold with low energy consumption. Intelligent shading systems also ensure that rooms remain at a pleasant temperature in summer without air conditioning and that the heat remains in the room in winter.

The event was accompanied by an exhibition where participants were able to try out numerous smart products.

The annual User Forum is organized by the German Institutes of Textile and Fiber Research Denkendorf (DITF), the Textile Research Institute Thuringia-Vogtland e.V. (TITV Greiz) and the Forschungskuratorium Textil e. V. (FKT).

The next SMART TEXTILES User Forum will take place on March 4-5, 2026 in Zeulenroda.

Klopman, a European leader in the production of fabrics for workwear, and TDV Industries, a France-based company specializing in textiles for technical and military clothing, completed an innovative project for the creation of an advanced tool to calculate the Life Cycle Assessment of their fabrics. The tool has obtained the well-recognized EPD (Environmental Product Declaration) certification from Environdec.

The EPD certification validates the methodology and results of a product's Life Cycle Assessment (LCA), a rigorous methodology that evaluates the environmental impact of a given product throughout all phases of its life cycle: from raw material extraction to production, usage, and disposal. This approach provides a comprehensive and accurate overview of environmental impacts, and the production processes involved. LCA allows for the measurement of parameters such as greenhouse gas emissions, energy consumption, water usage, and other environmental indicators, offering a scientific basis for improving efficiency and reducing the ecological footprint of products.

The Environmental Product Declaration (EPD) is a certified verification system that ensures a transparent and reliable assessment of a product's environmental impact. This certification follows international standards and enables companies to demonstrate their commitment to sustainability, improving transparency with customers and business partners.

Thanks to the new tool, Klopman and TDV Industries can now accurately calculate the environmental impact of each stage of their fabric production. This allows both companies to generate complete EPD certifications in compliance with international regulations, ensuring greater transparency and credibility for their products.

"Our Group has always been committed to sustainability projects, both within the company and regarding the products we bring to the market. Today, with this tool, we want to provide our customers with clear answers about the impact of our fabrics in terms of CO2 emissions, water, and land consumption, but also beyond that," says Amaury Sartorius, Group Commercial Director and Managing Director of Klopman. "The textile industry is undergoing a transition toward more sustainable production processes, and this project fits perfectly within this evolution. With this tool, we aim to produce fabrics with an increasingly lower environmental impact, thereby helping our customers in their sustainability and decarbonization journeys (such as SBTi).”

The Middle East’s industrial sector is synonymous with high-risk environments, particularly in oil and gas production. Workers face hazards such as flash fires, chemical splashes and electric arcs—all within the context of demanding conditions, including sweltering heat and long shifts. In response to these challenges, flame-retardant (FR) fabrics with stretch properties are emerging as the next generation of protective workwear, delivering comfort, safety and durability.

Traditionally, FR fabrics prioritised protection over comfort. However, the increasing demand for ergonomic clothing has driven a shift towards stretch solutions. Thanks to innovations in textile engineering and the influence of modern fashion, these fabrics now combine unparalleled flexibility with the stringent safety standards required in high-risk industries.

Stretch fabrics such as Carrington Textiles’ Flametougher 290AS Flex and Flameflex 300AS demonstrate how this transition is not just a luxury but a necessity. Flametougher 290AS Flex, for example, incorporates 19.5% CORDURA® nylon 6,6 for exceptional durability and strength, blended with 78% cotton for lightweight comfort. At just 290gsm, it ensures workers maintain mobility without compromising on protection.

Meeting the needs of Middle Eastern workers, Flameflex 300AS, weighing 300gsm, provides a perfect balance of durability, flexibility and flame resistance. Its 83% cotton and 14% polyester composition ensures longevity, while 2% EOL fibres enable enhanced elasticity—critical for workers in physically intensive roles such as oil rig operations or refinery maintenance.

Flexibility in workwear isn’t just a matter of comfort, it’s a matter of safety. Restricted movement can lead to fatigue, reduced compliance with safety standards and accidents. Stretch FR fabrics excel in adaptability. Whether it’s a worker scaling scaffolding on an oil platform or handling maintenance in a petrochemical plant, garments made with stretch FR textiles allow for the unrestricted movement critical to performing tasks safely.

The rise of these type of fabrics also owes much to the fashion industry. Decades of innovation in stretch garments for everyday use have created a ripple effect in workwear. Workers increasingly expect the same level of comfort and fit in their protective clothing, and manufacturers are responding.

Teijin Frontier Co., Ltd., the Teijin Group’s fibers and products converting company, announced the development of a new, multifunctional and comfortable polyester material that combines high breathability and UV protection. This new product reproduces the structure of a traditional Japanese "Sudare" blind (bamboo blind), which allows breezes to pass through while blocking out sunlight.

As extremely high summer temperatures become increasingly common, Teijin Frontier developed this new polyester to meet market demands for materials with enhanced heat protection functions. Heat protection encompasses breathability, UV resistance and anti-stickiness. However, until now, breathability – achieved by gaps between fibers – and UV protection were thought to be mutually exclusive.

To solve this dilemma, the company created a structure with slit-shaped, highly breathable areas in either the warp or weft direction of the fabric. These three-dimensional gaps, similar to those in a bamboo blind, allow the material to deliver both excellent breathability and high UV blocking performance of 85 percent or more. The structure allows air permeability of 50㎤/㎠・s or more.

This new product also offers sustainability benefits through the incorporation of recycled polyester in part. Its structure and elastic fibers provide stretch performance, while an uneven surface caused by differences in thread shrinkage and its structure avoid stickiness. Moreover, to achieve the combination of functions, Teijin Frontier also adopt special high-shrinkage technology and dying finishing technology. This material offers potential for use in both fashion and casual clothing.

Teijin Frontier will begin promoting this product for the 2025 spring and summer fashion and casual clothing collections in Japan, aiming for sales of 250,000 meters in fiscal 2024 and 750,000 meters in fiscal 2027.

Cavitec, part of Santex Rimar Group, presents the redesigned Caviscreen at Techtextil Frankfurt. Caviscreen features latest technology for breathable laminates.

Caviscreen was developed as a hotmelt coating and laminating unit for breathable sportswear, rainwear and protective clothing – with and without applying a membrane. The redesigned machine shows a brand-new method to supply adhesive more evenly and precisely. Using PUR adhesive (polyurethane reactive adhesive) goes with additional benefits like strong bonding capabilities and versatility.

Caviscreen’s hotmelt screen printing is a special system for high-end application garments. With this Caviscreen system, a PUR adhesive is transferred onto the substrate through a rotary screen, similar to the well-established textile printing method. The adhesives are fed from the drum melter through a heated hose to the traversing adhesive distribution system inside the rotary screen, just behind the doctor blade.

The adhesive is pressed by the doctor blade through the screen holes and transferred to the substrate. Different dot pattern (mesh or irregularly) and different screen thicknesses allow different coating weight and adhesive coverages.

The traversing adhesive dispenser is used to distribute the adhesive automatically over the set working width that – an additional technical benefit – can be set without any mechanical changes.

Cavitec’s screen coating system achieves high bonding strength while using less adhesive than other coating processes, because of applying the coating on the surface of the substrate and like this, the adhesive has less tendency to penetrate the substrate.

Bonding strength, softness of the fabric and the breathability are defined by the coating weight and the coverage. The rotary screen allows users to regulate and adapt the coverage respectively the coating weight. Cavitec offers a large selection of screens that are essential to fulfil the fabric requirements. A further advantage is the ease and efficiency of switching from one screen to another by simply unlocking the bayonet fitting. The IR-heater cover opens pneumatically and the lightweight screen can be easily removed by hand. Unlike with other methods, there's no need to deal with hot oil or any other heated liquid that requires cooling down.

The Caviscreen technology supports manufacturers by reducing costs with screens priced at a mere fraction, just 10%, of common gravure roller prices.

The combination of high strength and rigidity with sustainability and a neutral carbon footprint makes flax the ideal raw material for natural fibre-reinforced plastics. vombaur offers composite textiles made of this natural fibre for the automotive, wind power, construction or sports industries and many other sectors.

Flax fibres are rigid and tear-proof. They have natural bactericidal properties, are virtually antistatic, stain resistant and easy to spin. Humans have taken advantage of these properties to manufacture robust, stain-resistant and lint-free textiles. Between the late 19^th and late 20^th centuries, cotton largely replaced natural fibres. Because flax can be grown in Europe and consumes less energy and water than cotton production, the material's importance is currently growing again, for both clothing and composites. Regional textile value added chains in Europe – flax makes them possible.

Ideal mechanical properties
vombaur makes the mechanical properties of flax usable for lightweight design. Because flax fibres are particularly rigid and tear-resistant, they ensure great stability in natural fibre-reinforced plastics (NFRPs). And thanks to their low density of 1.50 g/cm3, the fibres weigh virtually nothing. On top of this, fibre-reinforced plastics are less prone to splintering than glass fibre-reinforced plastics.

Excellent carbon footprint
The cultivation of flax binds CO₂ and the production of natural fibre-reinforced plastics (NFRPs) generates approximately one third less CO₂ emissions compared with conventional fibre-reinforced plastics. Energy consumption is substantially lower. This saves resources. The use of flax fibre tapes by vombaur in lightweight design applications also improves the product's carbon footprint and contributes to a secure, regional supply chain.

Recycling without impacting on quality
Flax offers another sustainability benefit: more recycling cycles than glass- or carbon fibre-reinforced plastics – without impacting on quality. Thermoplastic fibre-matrix prepregs are melted and reused in the recycling process. The natural fibres can be used in other products such as natural fibre-reinforced injection moulded parts.

Sustainable product developments for many industries
"Orthoses for high-performance sports, high-tech skis, wind turbines, components for the automotive industry or aerospace, but also modern window profiles – the application scope for our lightweight design flax tapes is amazingly diverse", as Carl Mrusek, Chief Sales Officer at vombaur explains. "After all, wherever flax tapes are used, three key properties come together: light weight, strength and sustainability".

Albany International Corp. has completed its acquisition of Heimbach Group (Heimbach). Headquartered in Düren, Germany, Heimbach is a global supplier of paper machine clothing for the production of all grades of paper and cardboard on all machine types as well as high-tech textile products used in a variety of sectors, such as the food processing, chemicals, construction materials and automotive industries.

Daniel Halftermeyer, President of Machine Clothing, said, “We are excited about the opportunities to create additional value for our shareholders and customers through the increased scale, complementary technologies and broader geographic footprint this transaction provides. Together we will effectively combine the strengths of each company to set a new standard in customer value delivery as the industry’s partner-of-choice.”

Albany acquired Heimbach for €132 million in cash, and assumed net debt of approximately €22 million. The transaction was funded with cash held in Europe.

OETI – a member of the internationally active TESTEX Group – has bought the German company ECS to expand its service portfolio in the field of personal protective equipment (PPE).

OETI has been offering testing services for textile work clothing since 1983 – for about 40 years. Since the introduction of CE labelling for personal protective equipment and the enactment of the PPE Directive by the European Union in 1993, OETI has not only been testing textile personal protective equipment, but now on also certifies it in conformity with EU standards. In 1995, OETI was certified in Brussels as a Notified Body (0534) for type-examinations and quality assurance monitoring of personal protective equipment end products. Testing and certification is carried out in accordance with the current PPE Regulation (EU) 2016/425.

Testing and Certification Body for Eye and Face Protection, based in Aalen, was founded 15 years ago and is a globally active institution for testing and certification of eye and face protection equipment. The company is one of the leading independent testing institutions for personal protection products in laser applications and for welding work.

ECS tests and evaluates occupational health and safety goggles with and without a filter action, passive and active switching protection filters and shields for welders, and laser protection filters, goggles, and shields. The company also tests the optical properties of sunglasses, sports glasses, ski goggles, swimming goggles and motorbike goggles.

With OETI’s takeover, the ECS location in Aalen is retained, and all employees will continue working at ECS. The new Managing Director of ECS GmbH as of 1 July 2023 is Dipl.-Ing. Rolf Diebolder.

‘We are present on the European market, on the American market and, via a representative office, on the Chinese market. With the aid of the new distribution channels through OETI and TESTEX, we want to steadily advance ECS’ expansion and be present on all five continents’, says Managing Director Rolf Diebolder, explaining his strategic plans for ECS. ‘I would like OETI and ECS to develop a joint strategy in order to be able to offer existing and new customers of both companies a complete package which, when combined, will give us a unique selling point in the marketplace’, says Diebolder.

Diebolder also sees further potential in the cooperation with regard to protective laser clothing. According to him, this is where the laser laboratory commissioned by ECS could be used to make textiles laser-safe. In the future, there will be more and more ‘hand-held’ devices, i.e. laser welding devices, for which gloves and protective jackets are needed.

Many people across the world are bedridden – be it due to illness, an accident or old age. Because those affected often cannot move or turn over by themselves, they often end up with very painful bedsores. In the future, it should be possible to avoid bedsores with the help of materials that can be programmed to entirely adapt their form and mechanical properties. For example, the body support of mattresses made from programmable materials can be adjusted in any given area at the push of a button. Furthermore, the support layer is formed in such a way that strong pressure on one point can be distributed across a wider area. Areas of the bed where pressure is placed are automatically made softer and more elastic. Caregivers can also adjust the ergonomic lying position to best fit their patient.

Materials and microstructuring
Materials for applications requiring specific changes to stiffness or shape are being developed by researchers from Fraunhofer CPM, which is formed of six core institutes with the aim of designing and producing programmable materials. So, how can we program materials? “Essentially, there are two key areas where adjustments can be made: the base material – thermoplastic polymers in the case of mattresses and metallic alloys for other applications, including shape memory alloys – and, more specifically, the microstructure,” explains Dr. Heiko Andrä, spokesperson on the topic at the Fraunhofer Institute for Industrial Mathematics ITWM, one of the Fraunhofer CPM core institutes. “The microstructure of these metamaterials is made up of unit cells that consist of structural elements such as small beams and thin shells.” While the size of each unit cell and its structural elements in conventional cellular materials, like foams, vary randomly, the cells in the programmable materials are also variable – but can be precisely defined, i.e., programmed. This programming can be made, for example, in such a way that pressure on a particular position will result in specific changes at other regions of the mattress, i.e., increase the size of the contact surface and provide optimal support to certain areas of the body.

Materials can also react to temperature or humidity
The change in shape that the material should exhibit and the stimuli to which it reacts - mechanical stress, heat, moisture or even an electric or magnetic field - can be determined by the choice of material and its microstructure.

The journey to application
A single piece of material can take the place of entire systems of sensors, regulators and actuators. The goal of Fraunhofer CPM is to reduce the complexity of systems by integrating their functionalities into the material and reducing material diversity. We always have industrial products in mind when developing the programmable materials. As such, we take mass production processes and material fatigue into account, among other things,” says Franziska Wenz, deputy spokesperson on the topic at the Fraunhofer Institute for Mechanics of Materials IWM, another core institute of Fraunhofer CPM. The initial pilot projects with industry partners are also already underway. The research team expects that initially, programmable materials will act as replacements for components in existing systems or be used in special applications such as medical mattresses, comfortable chairs, variable damping shoe soles and protective clothing. “Gradually, the proportion of programmable materials used will increase,” says Andrä. Ultimately, they can be used everywhere – from medicine and sporting goods to soft robotics and even space research.

• ESD protection in harsh environments:
• Polymer-coated chemical-resistant fabrics and fireproof special textiles with expanded electrostatic discharge (ESD) safety function have been developed.
• Graphene nanotubes used as an electrostatic dissipative material make it possible to add ESD protection without compromising resistance to aggressive environments.
• Efficient working loadings starting from 0.06% are sufficient for stable anti-static properties fully compliant with safety standards and position graphene nanotubes far ahead of other conductive materials.

Protective clothing, upholstery, and industrial fabrics that experience harsh conditions require advanced performance. Depending on the final application, specialty textiles can be augmented with flame retardancy, durability, chemical protection, and other properties. Additionally, ESD protection is obligatory in the chemical, rescue, mining, oil & gas, automotive manufacturing, and many other industries that are subject to safety regulations.
 
In applications where multifunctionality of textile is required, graphene nanotubes overcome the limitations of other conductive materials such as unstable anti-static properties; degradation of strength, or chemical or fire resistance; complicated manufacturing processes; dusty production; carbon contamination on the material’s surface; or limited color options. Recent developments show that graphene nanotubes provide ESD protection to textiles in full compliance with safety standards and without degrading the textile’s resistance to harsh environments, greatly enhancing the value of textiles.
 
One such example is textiles coated with fluoroelastomer (a polymer that is highly resistant to chemicals) augmented with graphene nanotubes from OCSiAl. Nanotubes provide the material with surface resistivity of 10^6–10^8 Ω/sq compliant with EN, ISO, and ATEX standards for personal protective equipment. This new technology opens the door for the fabric to be used in high-level protective suits, combining exceptional protection from chemicals with electrostatic discharge protection.
 
Another example is how graphene nanotube technology is being acknowledged as a replacement for metal yarns in fireproof and anti-static textiles, protecting against sparks, splashes of molten metal, high temperatures, and the risk of sudden electrostatic discharge. While metal yarns require a specific knitting process and storage conditions, incorporating nanotubes in a fabric does not require any changes in the manufacturing process as the water-based dispersion is introduced into the fabric at the fluoro-organic treatment stage. The fabric with OCSiAl’s graphene nanotubes has been proven to maintain the pre-set level of ESD protection (surface resistance of 10^7 Ω) after numerous washes.
 
Permanent and stable electrical conductivity, facilitated by graphene nanotubes, is not only a matter of safety but brings additional value in augmenting dust-repellent properties and touchscreen compatibility for comfort and time savings. At the same time, the ultralow nanotube concentrations result in maintained manufacturing processes and mechanical properties, and improve product aesthetics by making it possible to use a wide range of colors. Altogether, these benefits allow textile manufacturers to create next-generation special textiles with expanded functionality.
