Co-friendly textiles without PFAS

Rain jackets, swimming trunks or upholstery fabrics: Textiles with water-repellent properties require chemical impregnation. Although fluorine-containing PFAS chemicals are effective, they are also harmful to human health and accumulate in the environment. Empa researchers are now developing a process with alternative substances that can be used to produce environmentally friendly water-repellent textile fibers. Initial analyses show: The "good" fibers repel water more effectively and dry faster than those of conventional products.

Rain jackets, swimming trunks or upholstery fabrics: Textiles with water-repellent properties require chemical impregnation. Although fluorine-containing PFAS chemicals are effective, they are also harmful to human health and accumulate in the environment. Empa researchers are now developing a process with alternative substances that can be used to produce environmentally friendly water-repellent textile fibers. Initial analyses show: The "good" fibers repel water more effectively and dry faster than those of conventional products.

If swimming trunks are to retain their shape after swimming and to dry quickly, they must combine two properties: They must be elastic and must not soak up water. Such a water-repellent effect can be achieved by treating the textiles with chemicals that give the elastic garment so-called hydrophobic properties. In the 1970s, new synthetic fluorine compounds began to be used for this purpose – compounds that seemed to offer countless application possibilities, but later turned out to be highly problematic. This is because these fluorocarbon compounds, PFAS for short, accumulate in the environment and are harmful to our health (see box). Empa researchers are therefore working with Swiss textile companies to develop alternative environmentally friendly processes that can be used to give fibers a water-repellent finish. Dirk Hegemann from Empa's Advanced Fibers laboratory in St. Gallen explains the Innosuisse-funded project: "We use so-called highly cross-linked siloxanes, which create silicone-like layers and – unlike fluorine-containing PFAS – are harmless."

Empa's plasma coating facilities range from handy table-top models to room-filling devices. For the coating of textile fibers, the siloxanes are atomized and activated in a reactive gas. They thereby retain their functional properties and enclose the textile fibers in a water-repellent coating that is only 30 nanometers thin. Fibers coated this way can then be processed into water-repellent textiles of all kinds, for example garments or technical textiles such as upholstery fabrics.

The advantage over conventional wet-chemical processes: Even with complex structured textiles, the seamless distribution of the hydrophobic substances is guaranteed right into all turns of the intertwined fibers. This is crucial, because even a tiny wettable spot would be enough for water to penetrate into the depths of a pair of swimming trunks, preventing the garment from drying quickly. "We have even succeeded in permanently impregnating more demanding, elastic fibers with the new process, which was previously not possible," says Hegemann.

Great interest from industry
In initial laboratory analyses, textiles made from the new fibers with an environmentally friendly coating are already performing slightly better than conventional PFAS-coated fabrics. They absorb less water and dry faster. However, the miraculous properties of the fluorine-free coating only really come into their own after the textiles have been washed several times: While the performance of conventional PFAS coatings in stretchy textiles declines considerably after repeated wash cycles, the fluorine-free fibers retain their water-repellent properties.

Hegemann and his team are now working on scaling up the fluorine-free laboratory process into efficient and economically viable industrial processes. "The industry is very interested in finding sustainable alternatives to PFAS," says Hegemann. The Swiss textile companies Lothos KLG, beag Bäumlin & Ernst AG and AG Cilander are already on board when it comes to developing environmentally friendly fluorine-free textiles. "This is a successful collaboration that combines materials, fiber technology and plasma coating and leads to an innovative, sustainable and effective solution," says Dominik Pregger from Lothos. And Bernd Schäfer, CEO of beag, adds: "The technology is environmentally friendly and also has interesting economic potential."

Adhesives: Feathers replace petroleum

Adhesives are almost always based on fossil raw materials such as petroleum. Researchers at Fraunhofer have recently developed a process that allows to utilize keratin for this purpose. This highly versatile protein compound can be found, for instance, in chicken feathers. Not only can it be used to manufacture a host of different adhesives for a variety of applications, but the processes and end products are also sustainable and follow the basic principles underlying a bioinspired circular economy. The project, developed together with Henkel AG & Co. KGaA, addresses a billion-dollar market.

The project, developed together with Henkel AG & Co. KGaA, addresses a billion-dollar market.

Adhesives are found nearly everywhere: in sports shoes, smartphones, floor coverings, furniture, textiles or packaging. Even auto windshields are glued into place using adhesives. Experts recognize more than 1,000 different types of adhesives. These can bond almost every imaginable material to another. Adhesives weigh very little and so lend themselves to lightweight design. Surfaces bonded with adhesive do not warp because, unlike with screw fastenings, the load is distributed evenly. Adhesives do not rust, and seal out moisture. Surfaces bonded with adhesive are also less susceptible to vibration. Added to which, adhesives are inexpensive and relatively easy to work with.

Feathers from poultry meat production
Traditionally, adhesives have almost always been made from fossil raw materials such as petroleum. The Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB has recently adopted a different approach. Researchers there have been using feathers as a base material instead of petroleum. Feathers are a by-product of poultry meat production. They are destroyed or mixed into animal feed. But feathers are far too valuable to go to waste because they contain the structural protein keratin. This biopolymer is found in animals and makes up talons, claws, hooves or feathers. Its fibrous structure is extremely strong.

Why keratin is perfect for manufacturing adhesives
Keratin is a biodegradable and thus eco-friendly material whose structure has specific properties that make it particularly suitable for the manufacture of adhesives. Keratin's polymer structure, i.e., its very long-chain molecules, as well as its ability to undergo cross-linking reactions predestine it for the manufacture of various adhesives. “The properties required for adhesives are to some extent already inherent in the base material and only need to be unlocked, modified and activated,” explains project manager Dr. Michael Richter.

Platform chemical and specialty adhesives
Over the past three years, Fraunhofer IGB has been working with Henkel AG & Co. KGaA on the KERAbond project: “Specialty chemicals from customized functional keratin proteins” — Kera being short for keratin, combined with the English word bond. Henkel is a global market leader in the adhesives sector.

The partners in the project have recently developed and refined a new process. In the first stage, feathers received from the slaughterhouse are sterilized, washed and mechanically shredded. Next, an enzyme process splits the long-chain biopolymers or protein chains into short-chain polymers by means of hydrolysis.

The output product is a platform chemical that can serve as a base material for further development of specially formulated adhesives. “We use the process      and the platform chemical as a “toolbox” to integrate bio-enhanced properties into the end product,” says Richter. This means parameters can be specified for the target special adhesive such as curing time, elasticity, thermal properties or strength. Also, it’s not just adhesives that are easy to manufacture but also related substances such as hardeners, coatings or primers.

In the next stage, the Fraunhofer team set about converting the feathers on a large scale. Ramping up the process fell to the Fraunhofer Center for Chemical-Biotechnological Processes CBP in Leuna. The aim was to prove that the keratin-based platform chemicals can also be manufactured cost-efficiently on an industrial scale. This involved processing several kilograms of chicken feathers, with the material produced being used for promising initial material trials at Fraunhofer IGB and Henkel.

Foundations of a bioinspired economy
This bioinspired process is of particular significance for the Fraunhofer-Gesellschaft. Biotechnology is in fact one of the main fields of research for the Fraunhofer-Gesellschaft: “We draw our inspiration from functionality or properties that already exist in nature or in natural raw materials. And we attempt to translate these properties into products through innovative manufacturing methods. This generates a bioinspired cycle for valuable raw materials, Richter explains.

The project carries some economic weight. According to Statista, around one million tons of adhesives were manufactured in Germany alone in 2019. Total value is around 1.87 billion euros.

A patent application has been filed for the new process and an article published in a scientific journal. Two PhD students who have conducted extensive research on the project at Henkel and Fraunhofer are expected to complete their theses in the first quarter of 2024. This new keratin-based technology will allow a host of platform chemicals to be produced in a sustainable, bioinspired way.

The KERAbond project has been funded and supported over the past three years by Fachagentur Nachwachsende Rohstoffe (FNR) in Gülzow on behalf of the Federal Ministry of Food and Agriculture (BMEL) under the Renewable Resources Funding funding program (grant number 22014218).

The most tasteful kind of coating

Tiny external structures in the wax coating of blueberries give them their blue colour, researchers at the University of Bristol can reveal. This applies to lots of fruits that are the same colour including damsons, sloes and juniper berries.

In the study, published in Science Advances, researchers show why blueberries are blue despite the dark red colour of the pigments in the fruit skin. Their blue colour is instead provided by a layer of wax that surrounds the fruit which is made up of miniature structures that scatter blue and UV light. This gives blueberries their blue appearance to humans and blue-UV to birds. The chromatic blue-UV reflectance arises from the interaction of the randomly arranged crystal structures of the epicuticular wax with light.

This gives blueberries their blue appearance to humans and blue-UV to birds. The chromatic blue-UV reflectance arises from the interaction of the randomly arranged crystal structures of the epicuticular wax with light.

Rox Middleton, Research Fellow at Bristol’s School of Biological Sciences, explained: “The blue of blueberries can’t be ‘extracted’ by squishing – because it isn’t located in the pigmented juice that can be squeezed from the fruit. That was why we knew that there must be something strange about the colour.

“So we removed the wax and re-crystallised it on card and in doing so we were able to create a brand new blue-UV coating.”

The ultra-thin colourant is around two microns thick, and although less reflective, it’s visibly blue and reflects UV well, possibly paving the way for new colorant methods.

“It shows that nature has evolved to use a really neat trick, an ultrathin layer for an important colorant," added Rox.

Most plants are coated in a thin layer of wax which has multiple functions, many of them that scientists still don’t understand. They know that it can be very effective as a hydrophobic, self-cleaning coating.

However until now, researchers did not know how important the structure was for visible colouration.

Now the team plan to look at easier ways of recreating the coating and applying it. This could lead to a more sustainable, biocompatible and even edible UV and blue-reflective paint.

Furthermore these coatings could have the same multiple functions as natural biological ones that protect plants.

Rox added: “It was really interesting to find that there was an unknown coloration mechanism right under our noses, on popular fruits that we grow and eat all the time.

“It was even more exciting to be able to reproduce that colour by harvesting the wax to make a new blue coating that no-one’s seen before.

“Building all that functionality of this natural wax into artificially engineered materials is the dream!”

Cooling down with Nanodiamonds

Researchers from RMIT University are using nanodiamonds to create smart textiles that can cool people down faster.

The study found fabric made from cotton coated with nanodiamonds, using a method called electrospinning, showed a reduction of 2-3 degrees Celsius during the cooling down process compared to untreated cotton. They do this by drawing out body heat and releasing it from the fabric – a result of the incredible thermal conductivity of nanodiamonds.

Published in Polymers for Advanced Technologies, project lead and Senior Lecturer, Dr Shadi Houshyar, said there was a big opportunity to use these insights to create new textiles for sportswear and even personal protective clothing, such as underlayers to keep fire fighters cool.

The study also found nanodiamonds increased the UV protection of cotton, making it ideal for outdoor summer clothing.

Published in Polymers for Advanced Technologies, project lead and Senior Lecturer, Dr Shadi Houshyar, said there was a big opportunity to use these insights to create new textiles for sportswear and even personal protective clothing, such as underlayers to keep fire fighters cool.

The study also found nanodiamonds increased the UV protection of cotton, making it ideal for outdoor summer clothing.

“While 2 or 3 degrees may not seem like much of a change, it does make a difference in comfort and health impacts over extended periods and in practical terms, could be the difference between keeping your air conditioner off or turning it on,” Houshyar said. “There’s also potential to explore how nanodiamonds can be used to protect buildings from overheating, which can lead to environmental benefits.”

The use of this fabric in clothing was projected to lead to a 20-30% energy saving due to lower use of air conditioning.

Based in the Centre for Materials Innovation and Future Fashion (CMIFF), the research team is made up of RMIT engineers and textile researchers who have strong expertise in developing next-generation smart textiles, as well as working with industry to develop realistic solutions.

Contrary to popular belief, nanodiamonds are not the same as the diamonds that adorn jewellery, said Houshyar. “They’re actually cheap to make — cheaper than graphene oxide and other types of carbon materials,” she said. “While they have a carbon lattice structure, they are much smaller in size. They’re also easy to make using methods like detonation or from waste materials.”

How it works
Cotton material was first coated with an adhesive, then electrospun with a polymer solution made from nanodiamonds, polyurethane and solvent.

This process creates a web of nanofibres on the cotton fibres, which are then cured to bond the two.

Lead researcher and research assistant, Dr Aisha Rehman, said the coating with nanodiamonds was deliberately applied to only one side of the fabric to restrict heat in the atmosphere from transferring back to the body.  

“The side of the fabric with the nanodiamond coating is what touches the skin. The nanodiamonds then transfer heat from the body into the air,” said Rehman, who worked on the study as part of her PhD. “Because nanodiamonds are such good thermal conductors, it does it faster than untreated fabric.”

Nanodiamonds were chosen for this study because of their strong thermal conductivity properties, said Rehman. Often used in IT, nanodiamonds can also help improve thermal properties of liquids and gels, as well as increase corrosive resistance in metals.

“Nanodiamonds are also biocompatible, so they’re safe for the human body. Therefore, it has great potential not just in textiles, but also in the biomedical field,” Rehman said.

While the research was still preliminary, Houshyar said this method of coating nanofibres onto textiles had strong commercial potential.
 
“This electrospinning approach is straightforward and can significantly reduce the variety of manufacturing steps compared to previously tested methods, which feature lengthy processes and wastage of nanodiamonds,” Houshyar said.

Further research will study the durability of the nanofibres, especially during the washing process.

Study tests firefighter turnout gear with, without PFAS


Transitioning away from per- and polyfluoroalkyl substances (PFAS), which offer water- and oil-repelling properties on the outer shells of firefighter turnout gear, could bring potential performance tradeoffs, according to a new study from North Carolina State University.

The study showed that turnout gear without PFAS outer shell coatings were not oil-repellent, posing a potential flammability hazard to firefighters if exposed to oil and flame, said Bryan Ormond, assistant professor of textile engineering, chemistry and science at NC State and corresponding author of a paper describing the research.

“All oil repellents can also repel water, but all water repellents don’t necessarily repel oil,” Ormond said. “Diesel fuel is really difficult to repel, as is hydraulic fluid; in our testing, PFAS-treated materials repel both. In our tests, turnout gear without PFAS repelled water but not oil or hydraulic fluid.

“All oil repellents can also repel water, but all water repellents don’t necessarily repel oil,” Ormond said. “Diesel fuel is really difficult to repel, as is hydraulic fluid; in our testing, PFAS-treated materials repel both. In our tests, turnout gear without PFAS repelled water but not oil or hydraulic fluid.

“Further, oils seem to spread out even more on the PFAS-free gear, potentially increasing the hazard.”

PFAS chemicals – known as forever chemicals because of their environmental persistence – are used in food packaging, cookware and cosmetics, among other uses, but have recently been implicated in higher risks of cancer, higher cholesterol levels and compromised immune systems in humans. In response, firefighters have sought alternative chemical compounds – like the hydrocarbon wax coating used in the study – on turnout gear to repel water and oils.

Besides testing the oil- and water-repelling properties of PFAS-treated and PFAS-free outer garments, the NC State researchers also compared how the outer shells aged in job-related exposures like weathering, high heat and repeated laundering, and whether the garments remained durable and withstood tears and rips.

The study showed that PFAS-treated and PFAS-free outer shells performed similarly after exposure to UV rays and various levels of heat and moisture, as well as passes through heating equipment – similar to a pizza oven – and through washing machines.

“Laundering the gear is actually very damaging to turnout gear because of the washing machine’s agitation and cleaning agents used,” Ormond said.

“We also performed chemical analyses to see what’s happening during the weathering process,” said Nur Mazumder, an NC State doctoral student in fiber and polymer science and lead author of the paper. “Are we losing the PFAS chemistries, the PFAS-free chemistries or both when we age the garments? It turns out that we lost significant amounts of both of these finishes after the aging tests.”

Both types of garments performed similarly when tested for strength against tearing the outer shell fabric. The researchers say the PFAS and PFAS-free coatings didn’t seem to affect this attribute.

Ormond said that future work will explore how much oil repellency is needed by firefighters out in the field.
“Even with PFAS treatment, you see a difference between a splash of fluid and soaked-in fluid,” Ormond said. “For all of its benefits, PFAS-treated gear, when soaked, is dangerous to firefighters. So we need to really ask ‘What do firefighters need?’ If you’re not experiencing this need for oil repellency, there’s no worry about switching to non-PFAS gear. But firefighters need to know the non-PFAS gear will absorb oil, regardless of what those oils are.”

Andrew Hall, another NC State doctoral student in fiber and polymer science and co-author on the paper, is also testing dermal absorption, or taking the aged outer shell materials and placing them on a skin surrogate for a day or two. Are outer shell chemicals absorbed in the skin surrogate after these admittedly extreme exposure durations?

“Firefighting as a job is classified as a carcinogen but it shouldn’t have to be,” Ormond said. “How do we make better gear for them? How do we come up with better finishes and strategies for them?

“These aren’t just fabrics,” Ormond said. “They are highly engineered pieces of material that aren’t easily replaced.”

The paper appears in the Journal of Industrial Textiles. Funding for the research came from the Federal Emergency Management Agency’s Assistance to Firefighters Grants Program.

Antimicrobial coating: Bacteria, stay out!

Hospital germs and pathogens are not always transmitted directly from person to person. They can also spread via germ-contaminated surfaces and objects. Empa researchers, together with the chemical company BASF, Spiez Laboratory and the Technical University of Berlin, have now developed coated textiles that inhibit or even kill pathogens. They could be used as antimicrobial curtains in hospitals in the future.

Hospital germs and pathogens are not always transmitted directly from person to person. They can also spread via germ-contaminated surfaces and objects. Empa researchers, together with the chemical company BASF, Spiez Laboratory and the Technical University of Berlin, have now developed coated textiles that inhibit or even kill pathogens. They could be used as antimicrobial curtains in hospitals in the future.

Countless times a day, patients, visitors and medical staff in hospitals touch surfaces of all kinds. Door handles, railings or elevator buttons can serve as transport vehicles for pathogens such as hospital germs or viruses. Smooth surfaces are comparatively easy to clean after contamination. With porous structures such as textiles, however, this is not that simple. Empa researchers have solved this problem together with experts from BASF, Spiez Laboratory and the Technical University of Berlin: A coating process can now be used to treat fabrics in such a way that bacterial and viral pathogens are killed or inhibited in their growth. In hospitals, the coated textiles could be used in future as antimicrobial curtains between patient beds, for example.

Active for months
"We were looking for a process that reliably prevents germs from contaminating textiles that come into contact with a large number of people during use," explains Peter Wick from Empa's Particles-Biology Interactions laboratory in St. Gallen. In this way, chains of infection could be interrupted in which multi-resistant bacteria or viral pathogens, for example, settle on hospital curtains and can then be spread by people.

The researchers ultimately developed a coating process in which a benzalkonium chloride-containing disinfectant was evenly applied to hospital curtains. After optimizing parameters such as concentration, exposure time, processing pressure and drying, the coating adhered stably to the textile surface. But did the coated textiles also exhibit a germicidal effect? This was to be shown by analyzing the antimicrobial activity of the first fabric samples.

"The results of the laboratory tests were very encouraging," says Wick. When the bacterial cultures of some typical problem germs were incubated with the fabric samples, the coated textiles inhibited the growth of staphylococci and pseudomonas bacteria, for example. "The hospital germs were significantly reduced or even killed after just ten minutes of exposure," says the Empa researcher. Moreover, the coating was also active against viral pathogens: Over 99 percent of the viruses were killed by the coated fabric samples.

Another advantage: The coatings remained effective even after several months of storage. This allows production in stock. With the new process, other textiles, filters or cleaning utensils could also be quickly and safely treated with antimicrobials in the future, for example in the event of an epidemic, emphasizes Empa researcher Wick.

Silk Provides the Building Blocks to Transform Modern Medicine

Tufts researchers harness protein from silk to make virus-sensing gloves, surgical screws that dissolve in your body, and other next-generation biomedical materials

About a mile northwest of Tufts’ Medford/Somerville campus, on the fourth floor of a refurbished woolen factory, there is a shrine to silk. Glass vases filled with silkworm cocoons and washed silk fibers sit artfully on a shelf across from a colorful drawing of the life cycle of Bombyx mori, the domesticated silk moth. Farther in, more cocoons in wall-mounted cases border a large, close-up image of silk fibers, and displays hold dozens of prototypes made from silk, including smart fabrics, biosensors, a helmet that changes color upon impact, and potential replacements for materials like leather, plastic, and particle board.

About a mile northwest of Tufts’ Medford/Somerville campus, on the fourth floor of a refurbished woolen factory, there is a shrine to silk. Glass vases filled with silkworm cocoons and washed silk fibers sit artfully on a shelf across from a colorful drawing of the life cycle of Bombyx mori, the domesticated silk moth. Farther in, more cocoons in wall-mounted cases border a large, close-up image of silk fibers, and displays hold dozens of prototypes made from silk, including smart fabrics, biosensors, a helmet that changes color upon impact, and potential replacements for materials like leather, plastic, and particle board.

The only things missing are the silkworms themselves, but Fiorenzo Omenetto, the director of Silklab and the Frank C. Doble Professor of Engineering at Tufts, said they will be arriving soon. The lab is building a terrarium so that visitors can view the animals.
“We’re going to have a celebration of silkworms and moths,” Omenetto said.

Silk has been cultivated and harvested for thousands of years. It is best known for the strong, shimmering fabric that can be woven from its fibers, but it also has a long history of use in medicine to dress injuries and suture wounds. At Silklab, Omenetto and his colleagues are building on silk’s legacy, proving that this ancient fiber could help create the next generation of biomedical materials.

Silk moth caterpillars, known as silkworms, extrude a single sticky strand of silk from their mouths to form cocoons, which are harvested by silk farmers to make silk thread. At its core, silk is a mixture of two proteins: fibroin, which provides the fiber’s structure, and sericin, which binds it together. With a few steps in the lab, Tufts researchers can remove the sericin and dissolve the fibers, turning a dry cocoon into a fibroin-filled liquid.

“Nature builds structural proteins that are very tough and very strong,” Omenetto said. “Your bricks are these fibroin proteins floating in water. From there, you can build whatever you want.”
Starting with shipments of dried cocoons from silk farms, Omenetto and his colleagues have been able to create gels, sponges, clear plastic-like sheets, printable inks, solids that look like amber, dippable coatings, and much more.

“Each of the materials that you make can contain all these different functions, and there’s only 24 hours in a day,” Omenetto said with a laugh. “This is why I don’t sleep.”

Biocompatible and Biodegradable
When Omenetto arrived at Tufts almost two decades ago, his research was focused on lasers and optics—silk wasn’t in the picture. But a chance conversation with David Kaplan, the Stern Family Professor of Engineering and chair of the biomedical engineering department, set him on a new path.

Kaplan, who has been working with silk since the early ’90s, was designing a silk scaffold that would help rebuild a person’s cornea, allowing cells to grow between the layers. He needed a way to ensure that the growing cells would have enough oxygen and showed the small, transparent sheet to Omenetto, who was immediately intrigued by the material. Omenetto was able to use his lab’s lasers to put tiny holes in Kaplan’s silk cornea. More collaborations quickly followed.
“We’ve worked together incessantly since then,” Kaplan said.

One of those lines of research has been finding ways to use silk to help repair and regrow bone, blood vessels, nerves, and other tissue. Silk is biocompatible, meaning it doesn’t cause harm in the body and breaks down in predictable ways. With the right preparation, silk materials can provide necessary strength and structure while the body is healing.

“You can mold and shape silk to whatever you need, and it will hold that volume while the native tissue regrows into the space and the silk material degrades,” Kaplan said. “Eventually it’s 100 percent gone, and you’re back to your normal tissue.”

Some of this work has already been approved for use by the U.S. Food and Drug Administration. A company called Sofregen, which spun out of Kaplan and Omenetto’s research, is using an injectable silk-based gel to repair damaged vocal cords, the tissues that regulate air flow and help us speak.

On their own, sturdy silk structures can keep their size, shape, and function for years before degrading. But in some instances, such as those involving surgical screws and plates intended for use in rapidly growing children, this pace would be too slow. The researchers had to find a way to speed up the time it takes for dense silk biomaterials to break down. They introduced an enzyme that our bodies produce naturally into the silk to hasten the breakdown process. The idea is that the enzyme would sit dry and inactive within the silk device until the structure is installed in a person, then the device would hydrate and activate the enzyme to digest the material more rapidly.

“We can titer in just the right amount of enzyme to make a screw go away in a week, a month, a year,” Kaplan said. “We have control over the process.”

Currently, Kaplan and his lab are working on other small, degradable medical devices that would help cut down on the number of surgeries that patients need. Ear tubes, for example, are often surgically implanted to help alleviate chronic ear infections and then need to be surgically removed. Kaplan and his colleagues have designed silk-based ear tubes that degrade on their own and can even carry antibiotics.

“As someone with a daughter who went through six surgeries on her ear, I know how helpful this could be,” Kaplan said.

Pyrolysis processes promise sustainable recycling of fiber composites

Wind turbines typically operate for 20 to 30 years before they are undergoing dismantling and recycling. However, the recycling of fiber composites, especially from the thick-walled rotor blade parts, has been inadequate until now. The prevailing methods involve thermal or mechanical recycling. For a sustainable and holistic recycling process, a research consortium led by Fraunhofer IFAM is pooling their expertise to recover the fibers through pyrolysis. Subsequent surface treatment and quality testing of the recyclates allow for them to be used again in industry.

Wind turbines typically operate for 20 to 30 years before they are undergoing dismantling and recycling. However, the recycling of fiber composites, especially from the thick-walled rotor blade parts, has been inadequate until now. The prevailing methods involve thermal or mechanical recycling. For a sustainable and holistic recycling process, a research consortium led by Fraunhofer IFAM is pooling their expertise to recover the fibers through pyrolysis. Subsequent surface treatment and quality testing of the recyclates allow for them to be used again in industry.

Today, the vast majority of wind turbines can already be recycled cleanly. In the case of rotor blades, however, recycling is only just beginning. Due to the 20-year operation period and the installation rates, the blade volume for recycling will be increasing in the coming years and decades. In 2000, for example, around 6,000 wind turbines were erected in Germany, which now need to be fed into a sustainable recycling process. In 2022, about 30,000 onshore and offshore wind turbines with a capacity of 65 gigawatts were in operation in Germany alone.

As wind energy is the most important cornerstone for a climate-neutral power supply, the German government has set itself the goal of further increasing its wind energy capacity by 2030 by installing larger and more modern turbines. Rotor blades will become longer, the proportion of carbon fibers used will continue to increase - and so will the amount of waste. In addition, the existing material mix in rotor blades is expected to increase in the future and precise knowledge of the structure of the components will become even more important for recycling. This underscores the urgency of developing sustainable processing methods, especially for recycling the thick-walled fiber composites in the rotor blades.

Economic and ecological recycling solution for fiber composites on the horizon
Rotor blades of wind turbines currently up for recycling consist of more than 85 percent of glass- and carbon-fiber-reinforced thermosets (GFRP/CFRP). A large proportion of these materials is found in the flange and root area and within the fiber-reinforced straps as thick-walled laminates with a wall thicknesses of up to 150 mm. Research into high-quality material fiber recycling as continuous fibers is of particular importance, not only because of the energy required for carbon fiber production. This is where the project "Pyrolysis of thick-walled fiber composites as a key innovation in the recycling process for wind turbine rotor blades" – "RE SORT" for short – funded by the German Federal Ministry of Economics and Climate Protection comes in. The aim of the project team is the complete recycling by means of pyrolysis.

A prerequisite for high-quality recycling of fiber composites is the separation of the fibers from the mostly thermoset matrix. Although pyrolysis is a suitable process for this purpose, it has not yet gained widespread adoption. Within the project, the project partners are therefore investigating and developing pyrolysis technologies that make the recycling of thick-walled fiber composite structures economically feasible and are technically different from the recycling processes commonly used for fiber composites today. Both quasi-continuous batch and microwave pyrolysis are being considered.

Batch pyrolysis, which is being developed within the project, is a pyrolysis process in which the thermoset matrix of thick fiber composite components is slowly decomposed into oily and especially gaseous hydrocarbon compounds by external heating. In microwave pyrolysis, energy is supplied by the absorption of microwave radiation, resulting in internal rapid heat generation. Quasi-continuous batch pyrolysis as well as microwave pyrolysis allow the separation of pyrolysis gases or oils. The planned continuous microwave pyrolysis also allows for the fibers to be preserved and reused in their full length.

How the circular economy succeeds - holistic utilization of the recycled products obtained
In the next step, the surfaces of the recovered recycled fibers are prepared by means of atmospheric plasmas and wet-chemical coatings to ensure their suitability for reuse in industrial applications. Finally, strength tests can be used to decide whether the recycled fibers will be used again in the wind energy industry or, for example, in the automotive or sporting goods sectors.

The pyrolysis oils and pyrolysis gases obtained in batch and microwave pyrolysis are evaluated with respect to their usability as raw materials for polymer synthesis (pyrolysis oils) or as energy sources for energy use in combined heat and power (CHP) plants (pyrolysis gases).

Both quasi-continuous batch pyrolysis and continuous-flow microwave pyrolysis promise economical operation and a significant reduction in the environmental footprint of wind energy. Therefore, the chances for a technical implementation and utilization of the project results are very good, so that this project can make a decisive contribution to the achievement of the sustainability and climate goals of the German Federal Government.

‘Smart’ Coating Could Make Fabrics into Protective Gear

Precisely applied metal-organic technology detects and captures toxic gases in air.

A durable copper-based coating developed by Dartmouth researchers can be precisely integrated into fabric to create responsive and reusable materials such as protective equipment, environmental sensors, and smart filters, according to a recent study.
 
The coating responds to the presence of toxic gases in the air by converting them into less toxic substances that become trapped in the fabric, the team reports in Journal of the American Chemical Society.

Precisely applied metal-organic technology detects and captures toxic gases in air.

A durable copper-based coating developed by Dartmouth researchers can be precisely integrated into fabric to create responsive and reusable materials such as protective equipment, environmental sensors, and smart filters, according to a recent study.
 
The coating responds to the presence of toxic gases in the air by converting them into less toxic substances that become trapped in the fabric, the team reports in Journal of the American Chemical Society.

The findings hinge on a conductive metal-organic technology, or framework, developed in the laboratory of corresponding author Katherine Mirica, an associate professor of chemistry. First reported in JACS in 2017, the framework was a simple coating that could be layered onto cotton and polyester to create smart fabrics the researchers named SOFT—Self-Organized Framework on Textiles. Their paper demonstrated that SOFT smart fabrics could detect and capture toxic substances in the surrounding environment.

For the newest study, the researchers found that—instead of the simple coating reported in 2017—they can precisely embed the framework into fabrics using a copper precursor that allows them to create specific patterns and more effectively fill in the tiny gaps and holes between threads.

The researchers found that the framework technology effectively converted the toxin nitric oxide into nitrite and nitrate, and transformed the poisonous, flammable gas hydrogen sulfide into copper sulfide. They also report that the framework’s ability to capture and convert toxic materials withstood wear and tear, as well as standard washing.
 
The versatility and durability the new method provides would allow the framework to be applied for specific uses and in more precise locations, such as a sensor on protective clothing, or as a filter in a particular environment, Mirica said.

“This new method of deposition means that the electronic textiles could potentially interface with a broader range of systems because they’re so robust,” she said. “This technological advance paves the way for other applications of the framework’s combined filtration and sensing abilities that could be valuable in biomedical settings and environmental remediation.”
The technique also could eventually be a low-cost alternative to technologies that are cost prohibitive and limited in where they can be deployed by needing an energy source, or—such as catalytic converters in automobiles—rare metals, Mirica said.
 
“Here we’re relying on an Earth-abundant matter to detoxify toxic chemicals, and we’re doing it without any input of outside energy, so we don’t need high temperature or electric current to achieve that function,” Mirica said.

Co-first author Michael Ko, initially observed the new process in 2018 as he attempted to deposit the metal-organic framework onto thin-film copper-based electrodes, Mirica said. But the copper electrodes would be replaced by the framework.

“He wanted it on top of the electrodes, not to replace them,” Mirica said. “It took us four years to figure out what was happening and how it was beneficial. It’s a very straightforward process, but the chemistry behind it is not and it took us some time and additional involvement of students and collaborators to understand that.”

The team discovered that the metal-organic framework “grows” over copper, replacing it with a material with the ability to filter and convert toxic gases, Mirica said. Ko and co-author Lukasz Mendecki, a postdoctoral scholar in the Mirica Group from 2017-18, investigated methods for applying the framework material to fabric in specific designs and patterns.

Co-first author Aileen Eagleton, who is also in the Mirica Group, finalized the technique by optimizing the process for imprinting the metal-organic framework onto fabric, as well as identifying how its structure and properties are influenced by chemical exposure and reaction conditions.

Future work will focus on developing new multifunctional framework materials and scaling up the process of embedding the metal-organic coatings into fabric, Mirica said.

Advanced Fibers: When damaged ropes change color

High-performance fibres that have been exposed to high temperatures usually lose their mechanical properties undetected and, in the worst case, can tear precisely when lives depend on them. For example, safety ropes used by fire brigades or suspension ropes for heavy loads on construction sites. Empa researchers have now developed a coating that changes color when exposed to high temperatures through friction or fire.

The firefighter runs into the burning building and systematically searches room by room for people in need of rescue. Attached to him is a safety rope at the other end of which his colleagues are waiting outside in front of the building. In an emergency - should he lose consciousness for any reason - they can pull him out of the building or follow him into the building for rescue. However, if this rope has been exposed to excessive heat during previous operations, it may tear apart. This means danger to life!

The firefighter runs into the burning building and systematically searches room by room for people in need of rescue. Attached to him is a safety rope at the other end of which his colleagues are waiting outside in front of the building. In an emergency - should he lose consciousness for any reason - they can pull him out of the building or follow him into the building for rescue. However, if this rope has been exposed to excessive heat during previous operations, it may tear apart. This means danger to life!

And up to now there has been no way of noticing this damage to the rope. 2021 a team of researchers from Empa and ETH Zurich has developed a coating which changes color due to the physical reaction with heat, thus clearly indicating whether a rope will continue to provide the safety it promises in the future.

Researchers from ETH Zurich and Empa developed a coating system in 2018 as part of a Master's thesis, which the Empa team was now able to apply to fibers. "It was a process involving several steps," says Dirk Hegemann from Empa's Advances Fibers lab. The first coatings only worked on smooth surfaces, so the method first had to be adapted so that it would also work on curved surfaces. Empa has extensive know-how in the coating of fibers - Hegemann and his team have already developed electrically conductive fibers in the past. The so-called sputtering process has now also been successfully applied to the latest coating.

Three layers are required to ensure that the fiber actually changes color when heated. The researchers apply silver to the fibre itself, in this case PET (i.e. polyester) and VectranTM, a high-tech fibre. This serves as a reflector - in other words, as a metallic base layer. This is followed by an intermediate layer of titanium nitrogen oxide, which ensures that the silver remains stable. And only then follows the amorphous layer that causes the color change: Germanium-antimony tellurium (GST), which is just 20 nanometers thick. When this layer is exposed to elevated temperatures, it crystallizes, changing the color from blue to white. The colour change is based on a physical phenomenon known as interference. Two different waves (e.g. light) meet and amplify or weaken each other. Depending on the chemical composition of the temperature-sensitive layer, this color change can be adjusted to a temperature range between 100 and 400 degrees and thus adapted to the mechanical properties of the fiber type.

Tailor-made solutions
The possible areas of application for the colour-changing fibres are still open, and Hegemann is currently looking for possible project partners. In addition to safety equipment for firefighters or mountaineers, the fibres can also be used for load ropes in production facilities, on construction sites, etc. In any case, research on the subject is far from complete. At present, it is not yet possible to store the fibers for long periods of time without losing their functionality. "Unfortunately, the phase-change materials oxidize over the course of a few months," says Hegemann. This means that the corresponding phase change - crystallization - no longer takes place, even with heat, and the rope thus loses its "warning signal". In any case, it has been proven that the principle works, and durability is a topic for future research, says Hegemann. "As soon as the first partners from industry register their interest in our own products, the fibers can be further optimized according to their needs".

NGST - Next Generation Protective Textiles

  • Efficient Production of Novel, High-Quality Infection-Protective Textiles

 
Considerable shortages of protective textiles, especially respirators, occurred during the SARS-CoV-2 pandemic, which were exacerbated by the lack of sufficient production capacity in Germany and the EU at the time. Short-term retooling at EU companies as well as importing goods often did not lead to success, as these protective textiles were of highly variable quality, which had a negative impact on safety.

The "Next Generation Protective Textiles" initiative aims to remedy this situation by researching new approaches for the production of high-quality protective textiles.

The "NGST" project is divided into several subtasks
The project includes:

  • Efficient Production of Novel, High-Quality Infection-Protective Textiles

The "Next Generation Protective Textiles" initiative aims to remedy this situation by researching new approaches for the production of high-quality protective textiles.

The "NGST" project is divided into several subtasks
The project includes:

  • qualified selection of basic materials
  • studies on up-scaling to create the conditions for a rapid expansion of production capacities
  • development of novel antiviral coatings
  • comprehensive biological and material science analysis to verify the improved properties and also to open up new methods of quality control.

The protective textiles to be developed in the project have a wide range of applications beyond use in the medical field and in civil protection. In principle, wherever immediate cleaning and disinfection are difficult or special filtration tasks are necessary, such as in mobile or stationary filter systems for air purification or for individual personal protection.

In this project, the Fraunhofer IGCV is researching the development of a manufacturing process for nonwovens as a basis for infection protection and filtration media based on wet nonwoven technology. Compared to the state of the art (meltblown technology), this is potentially characterised by significantly increased production capacities as well as increased flexibility with regard to material variety. The main challenges here are the very high quality requirements based on low basis weights for processing the finest possible micro-staple fibres..
          
Pursuing novel approaches to increase quality and productivity in the production of protective textiles
The aim is to provide optimised nonwoven materials as a starting material for subsequent antiviral coatings, and to assess and demonstrate the high technological potential of wet nonwoven technology in this field of application.

For this purpose, an existing pilot wetlaid nonwoven line was specifically modified on a pilot plant scale. This makes it possible to produce nonwoven materials from micro-staple fibres in the required very high quality in terms of uniformity, basis weight, blending and thickness profile with high reproducibility. A standard PP nonwoven was used as a comparison system, which was produced according to the current state of the art using meltblown technology. In addition to the PP comparison variants, however, the processing of PLA, viscose and PET staple fibres, among others, was also investigated. The focus here is on maximum fibre fineness (microfibres) in each case in order to achieve the largest possible specific fibre surface or effective area in the nonwoven. In order to emphasise the significantly increased flexibility of wetlaid technology, particularly innovative variants based on modified bi-component fibres with maximised fibre surface area as well as split fibres are also being conceptually tested.

In addition to aspects of direct material and process development, the scale of the pilot plant provides a comprehensive data basis for estimating a later scaling up to an industrial series. This should create a technological starting point for the ramp-up of an efficient, national production of fleece-based infection control materials based on wet-laying technology.

Protection against Corona: Materials research provides findings at institutes of the Zuse Community

As the year draws to a close, expectations are growing that protection against COVID-19 will soon be available. Until this is the case for large sections of the population, the successes achieved in research and industry to protect against the virus in 2020 offer a good starting point in the fight against corona and beyond. At institutes in the Zuse community, progress have been made not only in medical but also in materials research.

As the year draws to a close, expectations are growing that protection against COVID-19 will soon be available. Until this is the case for large sections of the population, the successes achieved in research and industry to protect against the virus in 2020 offer a good starting point in the fight against corona and beyond. At institutes in the Zuse community, progress have been made not only in medical but also in materials research.

These successes in materials research include innovations in the coating of surfaces. "In the wake of the pandemic, the demand for antiviral and antimicrobial surfaces has risen sharply, and we have successfully intensified our research in this area," explains Dr. Sebastian Spange, Head of Surface Technology at the Jena research institute INNOVENT. He expects to see an increasing number of products with antiviral surfaces in the future. "Our tests with model organisms show that an appropriate coating of surfaces works", emphasizes Spange. The spectrum of techniques used by INNOVENT includes flame treatment, plasma coating and the so-called Sol-Gel process, in which organic and inorganic substances can be combined in one layer at relatively low temperatures. According to Spange, materials for the coatings can be antibacterial metal compounds as well as natural substances with antiviral potential.

Nonwovens produced for mask manufacturers
In 2020, the textile expertise of numerous institutes in the Zuse community ensured that application-oriented research could prove its worth in the practical fight against pandemics. After the shortage of mask supplies in Germany at the beginning of the pandemic, textile research institutes reacted to the shortage by jumping into the breach. The Saxon Textile Research Institute (STFI), for example, converted its research facilities to the production of nonwovens to supply German and European manufacturers of particle filtering protective masks. "From March to November 2020, we supplied nonwovens to various manufacturers in order to provide the best possible support for mask production and thus help contain the pandemic. At a critical time for industry and the population, we were able to help relieve critical production capacity - an unaccustomed role for a research institute, but one we would assume again in similar situations," explains Andreas Berthel, Managing Commercial Director of STFI.

Development of reusable medical face masks
For the improvement of everyday as well as medical face masks the German Institutes for Textile and Fiber Research (DITF) are working on this project. In cooperation with an industrial partner, they are currently developing in Denkendorf, among other things, reusable medical face masks made of high-performance precision fabric using Jacquard weaving technology. The multiple use avoids waste and possible supply bottlenecks.

There are regulations for all types of masks, now also for everyday masks. At Hohenstein, compliance with standards for masks is checked. A new European guideline defines minimum requirements for the design, performance evaluation, labelling and packaging of everyday masks. "As a testing laboratory for medical products, we test the functionality of medical masks from microbiological-hygienic and physical aspects", explains Hohenstein's Managing Director Prof. Dr. Stefan Mecheels. In this way, Hohenstein supports manufacturers, among other things, with technical documentation to prove the effectiveness and safety. Respiratory protection masks (FFP 1, FFP 2 and FFP 3) have been tested at the Plastics Centre (SKZ) in Würzburg since the middle of this year. Among other things, inhalation and exhalation resistance and the passage of particles are tested. In addition, SKZ itself has entered into mask research. In cooperation with a medical technology specialist, SKZ is developing an innovative mask consisting of a cleanable and sterilizable mask carrier and replaceable filter elements.

ILK tests for mouth-nose protection
The fight against Corona is won by the contributions of humans: Of researchers in laboratories, of developers and manufacturers in the Industry as well as from the citizens on the street.
Against this background, the Institute for Air and Refrigeration Technology (ILK) in Dresden has carried out investigations into the permeability of the mouth and nose protection (MNS), namely on possible impairments when breathing through the mask as well as the protective function of everyday masks. Result: Although the materials used for the mouth-nose protection are able to retain about 95 percent of the exhaled droplets, "under practical aspects and consideration of leakages" it can be assumed that about 50 percent to 70 percent of the droplets enter the room, according to the ILK. If the mask is worn below the nose only, it can even be assumed that about 90 percent of the exhaled particles will enter the room due to the large proportion of nasal breathing. This illustrates the importance of tight-fitting and correctly worn mouth and nose protection. "On the other hand, from a physical point of view there are no reasons against wearing a mask", ILK managing director Prof. Dr. Uwe Franzke emphasizes. The researchers examined the CO2 content in the air we breathe as well as the higher effort required for breathing and based this on the criterion of overcoming the pressure loss. "The investigations on pressure loss showed a small, but practically irrelevant increase," explains Franzke.

The complete ILK report "Investigations on the effect of mouth and nose protection (MNS)" is available here.

Nopma - Experts for antimicrobial finishing: Technical textile coatings from the Swabian Alb

The Carl Meiser GmbH & Co. KG - started in the early 1950s as a day- and nightwear manufacturer. Over the last 20 years the company has become a specialist in the field of technical textiles. With its brand nopma Technical Textiles the company is present as developer and producer of textile solutions via coatings. The main products are nopma anti-slip - textiles with anti-slip effect, nopma adhesion - adhesive pre-coated films, spacer fabrics and substrates for lamination in automotive interiors, nopma ceramics - abrasive more resistant textile surfaces and nopma silicones - silicone coatings on textile surfaces.

Textination talked to the managing director, Jens Meiser, who joined the company in 2005, realigned the division and developed it into a service provider, about his plans and objectives.

The main products are nopma anti-slip - textiles with anti-slip effect, nopma adhesion - adhesive pre-coated films, spacer fabrics and substrates for lamination in automotive interiors, nopma ceramics - abrasive more resistant textile surfaces and nopma silicones - silicone coatings on textile surfaces.

Textination talked to the managing director, Jens Meiser, who joined the company in 2005, realigned the division and developed it into a service provider, about his plans and objectives.

Founded in 1952, Carl Meiser GmbH & Co.KG has changed from a day- and nightwear manufacturer to an innovator in the field of technical textiles, presenting themselves as a specialist for plastic-based coating processes. If you had to introduce yourself in 100 words to someone who does not know the company: What has influenced you most in this development process and what makes you unique?
Innovation is the new normal - This has been true for the textile industry not just since Sars CoV-2. Our industry was one of the first to be disrupted in the early 1990s and has always been subject to constant change. This urge for further development, which is essential for survival, has left its mark on us intensively and has enabled us to manage huge leaps in innovation in recent years

Today we regard ourselves as an innovative development and production service provider with a focus on textile coating. We develop and produce almost exclusively customized special solutions.

Through the combination of coatings on textiles these hybrid materials receive completely new properties.

You manufacture exclusively at your location in Germany. Why? Have you never been tempted to set up subsidiaries in other countries, for example to benefit from lower wage levels?
Today we supply global supply chains from our headquarter in southern Germany. Although we produce in a high-wage country, much more important for us are know-how and the drive of our team to create something new. Globalization will continue to be the key to success in the future. Therefore, subsidiaries in North America and Asia could be very interesting for us in the medium- and long-term perspective. However, this is still too early for us.

You use CIP and Kaizen techniques intensively in your company. How did a Japanese concept come about in the Swabian Alb?
KAIZEN, the change for the better, are actually German virtues. The urge to improve and optimize things is in all of us. Due to the continuous improvement process we do not stand still but evolve constantly. Besides, there is the personal affinity to Japan. A look at another culture simply opens the horizon. And if you additionally recognize parallels in the working methods, it’s even better. 

10 years ago, you turned your attention to new markets: aviation, automotive, protection, caravan and furniture manufacturing, to name just a few. Some of these segments have collapsed significantly during the Covid 19 pandemic. What market development do you expect in the medium term and what consequences will this have for your company?
Of course, the aviation or automotive industry, for example, have substantial problems during or due to the Covid-19 pandemic. Quite honestly, many of these problems existed before. They were further tightened, as if a fire accelerator has been used. Of course, these cut-backs are also hitting us hard economically. But we are pursuing long-term goals. As a medium-sized company, you have to have the resilience to continue on your path. Thanks to our specialisation and the split of our industrial sectors, which we drive forward every day, we manage to decouple ourselves more and more from economic developments in individual industries. For our customers this is a great advantage of relying on a very stable partner with long-term orientation.

We are positive about the future. Megatrends like sustainability, digitization and ongoing globalization will lead to new business models in the above-mentioned sectors, as in many others, and to renewed growth. Our coatings on textiles and flexible woven materials can contribute a wide range of solutions to this. If, for example, materials become lighter with identical usage properties or suddenly become biodegradable, because of biodegradable plastics, many new opportunities will arise.

Tailor-made instead of solutions for major customers: The topic of individualization down to batch size 1 is making up a large part of the discussion today. In 2015, you opened a large development laboratory where you have a wide range of testing technologies for textiles and plastics available. What do you think about individual product solutions, and in which application areas have you successfully implemented them?
In principle, we do not use any standards. We live individualization with the smallest possible batch sizes. In our field, we do not manage batch size 1, but we start with MOQs of 300 running meters at process-safe series production. We have very few finished products, and above all we have no collections. Our development laboratory is the key for this. Together with our customers we have the possibilities to realize very lean development processes.

Even on a laboratory scale, we can develop and test new products within just a few hours. We then strive to scale up to production at a very early stage in order to obtain production series results. This way, we offer our clients speed and power that represent a special potential for our partners.

You register important input factors in the production process and evaluate them in monthly environmental analyses. What are these factors in concrete terms and to what extent have their analyses already changed production operations? How do you define environmental management for your company?
For us, environmental management means a holistic approach. In principle, we operate production units and manufacture products that consume many resources. Due to the high production volumes, this continues to accumulate. Because of this, it is self-understanding that we record and evaluate our input and output flows and derive measures from them. This makes economic sense, but is also necessary because of our responsibility for our environment. Specifically, these are energy consumption values, consumption data of primary chemicals, electricity load peaks, our Co2 footprint, just to name a few. This consideration has changed us in many areas. Today we operate a power plant with gas condensing technology, our free roof areas are greened or carry photovoltaic modules, we offer our employees and visitors electric filling stations and finally we have converted the entire power supply of our factory to environmentally friendly hydroelectric power.

With nopma, you have been building up a brand for the technical textiles industry since several years and communicate this via an Individual website parallel to Carl Meiser GmbH & Co. KG. How did this brand name come about and what is the product portfolio behind it?
This is the name of a first technical textile product from the 1990s. It was a textile - coated with dots. Dots on a knitted fabric. NOPMA. My father created this brand.

In 2016 you invested in an additional production line for nopma products and were able to start a directly serial delivery in the NAFTA area. How do you currently assess the market opportunities for North America and Mexico?
We continue to see opportunities in globalization and thus on the North American market also. However, these markets are still severely affected by the pandemic and there are major distortions. When these return to normal, we surely will see more success on these markets again.

As an innovation leader, Meiser offers solvent-free PU adhesive systems as pre-coatings for lamination. How do you assess the importance of such innovations in the context of REACH?
These innovations offer our customers the opportunity to decouple themselves from the pressure REACH triggers in some industries. However, we also have some products that have been developed newly in recent months. This keeps us busy, but also creates opportunities to open up new market segments.

How have you felt about the corona era to date - as a company and personally? What would you on no account want to go through again and what might you even consider maintaining on a daily basis?
I think this time has also strengthened us as a society, as people and even as entrepreneurs. Each crisis you go through makes you a little more relaxed for the unforeseen, but also more motivated to achieve your goals. In my opinion, there have been a lot of positive things in the last few months. Suddenly, for example, digitalization tools have become accepted in our everyday lives, and I feel that people are paying more attention to others again. Hopefully this will stay this way.

The futuristic "tube" escalator at the Elbphilharmonie Concert Hall is just as impressive as the building itself and the longest escalator in western Europe. In August, a start-up based in Cologne installed an UV technology that keeps the handrails clean at all times. At the same time, you presented an antiviral functional coating that can be applied to all textiles in the form of yard goods. How does this work and for what purposes will this technology be suitable?
We have already been working with antimicrobial finishing techniques for many years. This already started with the swine flu in 2009/2010, when we made initial contacts with a young start-up and launched a development. Due to a lack of market interest, however, this had to be discontinued after a few months. Today we are experts in the field of "antimicrobial equipment by means of coatings". We were also able to build up an enormous amount of knowledge on the subject of approval and biocide regulation. Today, we can support our customers holistically in these areas. The function by skin-compatible active substances from the cosmetics sector with a vesicle booster can kill viruses and bacteria within a few minutes.
Since the pandemic has shown us the enormous importance of a new level of hygiene, the applications are very diverse and differentiated. We have already realized the use in personal protective equipment, work furniture, vehicles and for example gloves. In principle, every application is predestined where textile carriers are exposed to many touches by different persons in high frequency. Here our nopma products offer a new level of protection and hygiene.

To break new ground means decisiveness, overcoming fears - and thus the courage to fail. Not every project can succeed. In retrospect - about which entrepreneurial decision are you particularly glad to have made it?
We fail again and again. This is part of the game. But it has never happened that we did not learn anything. The pandemic situation is another good example. In spring we accepted our corporate responsibility for our society and were one of two companies in Baden-Württemberg to achieve certification for FFP protective masks. Since we did not want to participate in the revolver market at that time, we offered these products only to the public sector at favourable pre-crisis prices. However, the decision makers could not make up their minds for weeks and did not order. This disappointed our whole team very much at that time. Today we have overcome this and have taken a lot of knowledge with us from this development.

At least Europe seems to be able to breathe a sigh of relief after weeks of lockdown during the corona pandemic. The textile industry, an industry that has lived globalisation for so many years, is facing the challenge of maintaining its place in the new normal and building on its previous performance as quickly as possible.
Textination talked to three company representatives along the textile chain about personal and operational experiences.

The Interview with Michael Steidle, managing director at the textile printing company Heinrich Mayer GmbH, marks the provisional end of our series that started with Wolfgang Müller, Head of Sales & Services at Mayer & Cie. GmbH & Co. KG and was continued by Andreas Merkel, managing director of Gebr. Otto Baumwollfeinzwirnerei GmbH & Co. KG. The textile printing company Mayer, a family business on the Swabian Alb, is a leader in textile printing, in screen, rouleaux, rotary, sublimation and flock printing and as well as in 3D coating. They are increasingly using these skills in the area of technical textiles.

How have you felt about the corona era to date - as a company and personally?
What would you on no account want to go through again and what might you even consider maintaining on a daily basis?

 The corona time hit us hard. At the beginning of April, sometimes it felt like the lights would go out within the next 24 hours. In numbers there is a drop in sales of 30 percent.
And that's not just the way we are, this crisis has incredibly broader implications. Involved in the word of the Chamber of Commerce I am concerned with many companies in the region. Sectors that would not come to mind spontaneously also feel the effects. This also includes recycling companies. After all, there is also less commercial waste when companies are on short-time work.
At a personal level you can deal with the crisis, hand hygiene, sneeze etiquette, you can learn all of this. But we miss people-to-people contacts. We have a teenage daughter; young people in particular lack the ability to be out and about with their peers.

 
What has the pandemic meant for your company so far?
As I said, the Corona period brought us a significant drop in sales. That means we think twice before spending money. At the beginning of the year we moved to our new, spacious company building. There are still a few small investments to be made. So far, we have put it off until the situation has calmed down again. And so do many. The economic network extremely got out of hand due to the lockdown.
We applied for short-time work, which has been running for three months now. However, you have to see how long that makes sense. Our customers also had a drop in sales, which they first of all have to recover.

 
What adjustments or innovations to your product portfolio have you felt obliged by the pandemic to undertake?
The mask production was a very strong topic in April and May, the phone almost rang continuously. This enabled us to compensate for many orders that were lost otherwise.
We reacted quickly, not only printing masks classically, but also developing coatings for medical face masks and protective clothing. The coatings that we offer are antibacterial and have the lotus effect. This results in the formation of droplets in the aerosols. We have had checked and certified these innovations in an urgent procedure.
We converted our machines ad hoc so that we could apply innovative coatings instead of paint. This was even possible for ready-made masks.
In general, I rate this ability to react quickly as one of our great strengths. We are a small company, so the path from idea to implementation is rather short. If we recognize a trend, an opportunity in our industry, we examine ourselves: Do we have resources that could be used or adapted to offer a solid, marketable solution in a very short time? This refers to know-how, ideas, machines and, for larger projects, also partners. Experience has shown that on the one hand we have the necessary imagination, but on the other hand we also have a fairly realistic view of ourselves. If we can answer the question with “yes”, then we get started without delay. We can evaluate a trial in the evening and continue working on it the next day. There is no need for a meeting with five persons beforehand.
 

What are your views on global supply chains in the future, and will you be drawing consequences for your procurement policy?
We cannot avoid global supply chains; and it will remain this way. In the short term, you may reflect on regional procurement, as far as that is still possible. Many things are simply no longer available and the development over the past 30 years cannot be turned back. Let's take pigment paint: it comes from India and China, otherwise it doesn't exist anymore. Nobody in Europe can keep the prices. And yes, that also means that the production of systemically relevant products can no longer be guaranteed.

          
How do you rate the importance of partnerships within the industry in the future? Does Covid-19 have the potential to promote the creation of new cooperation arrangements in the industry? Or have they already taken shape?
Existing partnerships are important. We must keep the ball rolling: Interrupted projects have to be continued with existing partners.
I think it is important to maintain partnerships at eye level. Sure, now everyone has to see how they can make ends meet. It will be shown, however, who works loyally in the long term and with respect to the business.
Personally, it is important for me to be true to my word. Only a few days ago I spoke to a student, whom we promised her internship and a corresponding payment in February. This young woman can start her internship with us; what paying is concerned, I had to tell her honestly that we have to talk about it again. Fortunately, that was not a problem. It is important to the student that she can complete the required internship at all. This is not so easy since most companies do not accept anyone right now. That is understandable too, but we will need the well-trained people again soon, that’s for sure!

 
What initiatives or approaches for your industry would you welcome for the near future?
I would be very interested in a positive and comprehensive description of what value added is still available in Germany. An initiative that illustrates that the textile industry is an important industry, with many companies that have been family-owned for generations, often with a young, dynamic management and high-quality products. Really nobody has that on his radar. Just today, two designers from a company nearby visited us. They were surprised which services we offer in the field of technical textiles - they were not even aware of it.
The textile industry has played itself down for a long time, that has to stop. Of course, we no longer have added value like the machine building industry. But now, in the corona crisis, it would have been the right time to take advantage of the situation and to initiate much-needed lobbying..


What would you like to see as part of the German textile industry? Do you feel that the status of the German textile industry has changed as a result of the pandemic, especially in respect of public procurement?
No, only at very short notice. Everything was taken during the crisis, the main thing was that the requested product, i.e. masks and protective clothing, was even available. Now the old cycle is back: I have a certain budget, where can I get the most for it? This is frustrating because the willingness to face this challenge was high on the part of the companies.
We also have driven the development and had our coatings for masks certified in an urgent process. Others have switched their entire production at a significant cost to meet demand. Nobody became a millionaire this way.
I think the textile industry could have sold better here. We could and should have appeared better as noble knights. Unfortunately, this was lost in the heat of the battle.

Until now the big issues have been globalisation, sustainability / climate change / environmental protection, digitisation, the labour market situation and so on. Where do they stand now and how must we rate them against the backdrop of the Covid-19 pandemic?
We take sustainability into account with our certifications, with GOTS and ISO 9001. Digitisation does not work quickly for us; it will take years before we can digitise processes. Sure, in administration we are now increasingly working with web meetings and video conferences, but personal contact is important to me. I regularly give lectures; my next one will be at the Zurich University of Applied Sciences and I very much hope that it can take place. I am just a guy for direct contact.
The labour market situation depends on the pandemic and how it develops. In any case, it remains difficult to get young people excited about textile professions. When I open a mobile phone store, I don't need a day to have my employees together. When we present ourselves at a training fair, we are happy to have a handful of good conversations.
Training is so valuable. Someone who has one will always have a different status than an unskilled person, even if - at some point - he works in a completely different branch. The dual training system is absolutely untouchable for me, because we live from this economic performance. We have nothing else but our knowledge. And we have to keep developing because only the high level gives the necessary output.
 

What lessons are to be learnt in respect of these targets for the post-corona era?
Innovation, innovation, innovation. You must not stand still. Nobody knows what to do next. But in three years from now I have to live from what I am developing today, just like I live from what I developed three years ago. Now, in times of Corona, it is much harder to remember, but it does not help: I can’t stand still, waiting for what is happening next, being like a deer caught in the headlights.

‘WHAT SMELLS LESS HAS TO BE WASHED LESS OFTEN’

Swiss Quality Principles plus Innovation Strength: Hygiene and Material Protection from SANITIZED 

SANITIZED AG is known as a worldwide leading Swiss company in hygiene functions and material protection for textiles and plastics. Globally oriented, pioneering work is done with federal thoroughness in the development of innovative, effective and safe technologies for antimicrobial equipment. Textination had the opportunity to speak to CEO Urs Stalder about the growing importance of hygiene in times of the pandemic.

Swiss Quality Principles plus Innovation Strength: Hygiene and Material Protection from SANITIZED 

SANITIZED AG is known as a worldwide leading Swiss company in hygiene functions and material protection for textiles and plastics. Globally oriented, pioneering work is done with federal thoroughness in the development of innovative, effective and safe technologies for antimicrobial equipment. Textination had the opportunity to speak to CEO Urs Stalder about the growing importance of hygiene in times of the pandemic.

Founded in 1935, the majority ownership of the public company SANITIZED still lies with the founding families. You are the market leader in Europe in hygiene functions and material protection for textiles and plastics. If you had to introduce yourself in 100 words to someone who doesn't know the company: What influenced you in particular in the development of the company and what made it unique?
Preventing odor in shoes, that's how it started in 1935. This is where our business model came from: the antimicrobial protection of plastics and textiles.
SANITIZED develops ready-to-use additives that are individually tailored to the protection goals of the end products and that work, for example, against the development of odors in work clothing, against permastink (resilient odors) in synthetic textiles or against mold growth.
The 360-degree service is unique: This includes backing in product development, support for all regulatory questions and assistance with marketing topics.
SANITIZED AG is globally active and yet committed to Swiss quality principles. More than 400 brands worldwide use the ingredient brand Sanitized® on their end products.

Think global – act local? You have sister companies in France, the United States and Asia. Your roots and headquarters are based in Switzerland. The pandemic is currently increasing the question of intact supply chains. What does this mean for your company in the future?
Indeed, the broad global positioning enables us to do business locally. The local anchoring results in synergies, also in sourcing. That will be even more important for us in the future. And, of course, the issues of speed and customer proximity are also positive aspects of this approach.

From textiles to plastic surfaces to cans: SANITIZED Preservation AG was founded in 2018 to take care of colors and coatings. SANITIZED is thus opening up another market. Which markets are you particularly interested in and which product areas do you feel particularly challenged by?
Customers want paints and varnishes without solvents, which is better for people and the environment. But with the alternative water-based products, there is a high risk of contamination by microbes. This starts with the production, continues with the storage in the can and also in the application. The result is mold formation.
Antimicrobial protection for paints or coatings is particularly relevant in hygiene-sensitive areas of industrial production and, of course, in the medical environment. The risk of contamination and mold multiplies in regions with high air humidity. This is another reason why India is a growth market for this business area.   

To break new ground means decisiveness, overcoming fears - and thus the courage to fail. Not every project can succeed. In retrospect - about which entrepreneurial decision are you particularly glad to have made it?
Let me mention just three decisions that are important for corporate development: This is definitely the foundation of the SANITIZED Preservation division. This is about the antimicrobial protection of paints and varnishes. This also includes setting up our in-house TecCenter, in which we can perform laboratory services even faster. It was recently accredited by the International Antimicrobial Council. And right now it is the sales cooperation with Consolidates Pathway on the US market for our textile hygiene function solutions.

You state that innovation is embedded in the company's DNA. How do you live your inno-vation management and which role do the requirements of end consumers and your indus-trial customers play in this setting?
We ourselves as well as our global sales partners are in close contact with the manufacturers of textile products. This is also why we know the requirements and needs of the market. Sustainability is emerging from the niche in the mass market.
This is exactly what our product Sanitized® Odoractiv 10 has been developed for and awarded by the Swiss Innovation Award.
It is a dual-acting, biocide-free, patented technology against odor development and odor adsorption in textiles. Many customers appreciate our expertise and use it in the development of new products to create innovative textiles with additional benefits for the requirements of the market.

Tailor-made or solutions only for major customers? The topic of individualization up to lot size 1 takes up a lot of space today. What do you think about individual product solutions - or can you cover everything with the SANITIZED portfolio comprising 40 products?
We have a very versatile technology “kit” at our disposal. It is part of our daily business to respond individually to the special customer needs and the respective product requirements. We offer tailor-made recipes for this and our extensive application know-how flows into the advice for the individual application situation at the customer.

There are various definitions for sustainability. Customers expect everything under this term - from climate protection to ecology, from on-site production in the region to the ex-clusion of child labor, etc. Textile finishing does not always sound unproblematic. Public procurement is increasingly switching to sustainable textiles. What does this mean for SANITIZED and what do you do to bring the concept of sustainability to life for your company, and which activities and certifications do you focus on?
Resource conservation is a key issue for us. Since we “think” about the topic of sustainability along the entire production chain, including in research and development, resource-saving application techniques for the textile industry are important to us. Sanitized® additives can be integrated into standard production processes, so that additional energy is not required for complementary finishing processes.
Our portfolio also includes biocide-free products. Sanitized® Odoractiv10 prevents odors from sticking to textiles. Sanitized® Mintactiv uses the natural antibacterial effect of mint and was specially developed for cotton textiles.
And what smells less has to be washed less often. This saves water and electricity and extends the useful life of textiles.
          
SANITIZED supports its customers with a so-called 360° service. What do you mean by that and why don't you concentrate exclusively on the technical aspects of the products?
The SANITIZED brand wants to create real added value for its customers. That is why we have expanded our core competence as a developer and provider of innovative antimicrobial additives with an all-round service. The obvious thing to do is to support the production process, of course that is part of it. Furthermore; we also provide the latest knowledge on regulatory issues - world-wide. And we offer comprehensive marketing assistance for our license partners who use Sanitized® as an ingredient brand. Making correct advertising statements is important not only in times of Corona. Because it's always about transparency and security for people. Warning letters or delivery stops due to incorrect claims can be prevented.
Cooperation with the institutes is absolutely sensible; after all, it is their job to do research for com-panies that they cannot shoulder on their own. This includes testing facilities, as well as applying for funding, which is only possible in cooperation with research institutes. However, they are public institutions and therefore have different objectives per se than a company: We have to bring a promising idea to the market as quickly as possible to show a profit. A research institute does not have this pressure.

Which goal do you pursue with the website https://www.sanitized.house for example?
Yes, it may seem unusual when SANITIZED as a B2B company designs a platform for end customers. But more than 400 brands use Sanitized® as an ingredient brand. So, we are connected to the end customer in this way.
In the virtual house - Sanitized® the house -, visitors can playfully experience in which areas of life hygiene and material protection contribute to the quality of life. A click in the wardrobe links to products - including brand names - that have been equipped with Sanitized®: clothing in the wardrobe, the carpet in the living room or the towel in the bathroom. The best thing to do is try it yourself.

The company is working consistently on implementing Sanitized® as a brand. The hygiene function for textiles and plastics shall be documented and thus offer added value to customers and consumers. Co-branding is not always welcome, especially in the clothing, sports and outdoor sector. How rocky was the road until Sanitized® was advertised as an ingredient brand by 400 license partners on the product?
Of course, there are brands that do not want a second brand on their end product. But a trend is causing more and more manufacturers to rethink: Customers are increasingly asking questions about ingredients and their origins. Elucidation and transparency are growing needs. And that's exactly what we contribute to. In addition, this is an opportunity for a textile brand to stand out positively in the flood of suppliers. Differentiation through added value - donated by Swiss technology from SANITIZED. Those arguments work worldwide.

You have a diversified network. Just to mention to two of them - you have been a system partner since the foundation of bluesign® and you work closely with Archroma in sales matters. In which aspects do you see the special value of partnerships? Are there segments existing where you can imagine new partners and collaborations?
Partnerships are important and work if all pursue common goals and can mutually fertilize each other. For example, the partnership with the company Consolidates Pathway in the United States is brand new one.

For which socially relevant topics do you see a particularly great need for innovation and action in the next 5 years? What is your assessment that your company will be able to offer solutions for this with its products? And what role do the experiences from the corona pandemic play in this assessment?
Nobody can predict what the corona pandemic will change in the long term. Environmental protection and thus the conservation of our resources is and remains an important issue.
The fact that the textile industry can make a big contribution to this is slowly gaining awareness among the masses. Keywords are cheap production or water consumption for jeans production. People are becoming more sensitive to what companies and brands are doing. It will be all the more important to act and communicate openly and transparently.
For SANITIZED, it is a mission and a matter of course that only products with official approvals are used and that we work ac-cording to the bluesign principle. This is where traceability and transparency begin.

As a leader in textile printing, in screen, rouleaux, rotary, sublimation and flock printing and as well as in 3D coating, the enterprise is increasingly applying its leading expertise to the field of technical textiles. An in-house quality management system ensures the traceability of all production processes, an environmental portfolio the efficient use of energy, sustainability and resources. Textination talked to Managing Director Michael Steidle.

  • “Keep it up! is not an option"

The textile printing company Mayer is a family business on the Swabian Alb. As a leader in textile printing, in screen, rouleaux, rotary, sublimation and flock printing and as well as in 3D coating, the enterprise is increasingly applying its leading expertise to the field of technical textiles. An in-house quality management system ensures the traceability of all production processes, an environmental portfolio the efficient use of energy, sustainability and resources. Textination talked to Managing Director Michael Steidle.

Textildruckerei Heinrich Mayer GmbH is a family business that has been active in textile printing and finishing for 45 years. If you had to introduce yourself in 100 words to someone who doesn't know the company, what makes you unique?
Over the past ten years or so, our family-owned company based in rural Baden-Wurttemberg has changed from a classic textile printing company into a system supplier. A central precondition for this is our knowledge of our own strengths. We rely on proven printing solutions. We do not rush into exchanging them with the latest trend. Instead, we examine whether another, innovative application can be found for them. Or whether one it is possible to combine the tried and tested with a new approach. For example, we were able to solve electronic requirements by printing technology. This area is our second focus. I am a Master of electronic engineering and completed my apprenticeship at Bizerba, a worldwide leading specialist in industrial weighing and labeling technologies. My wife brought me to the textile industry.

In which product area do market and customers challenge you in particular? And on which socially relevant areas do you see a particularly great need for innovation in the upcoming 10 years? What is your assessment that textile finishing will be able to offer solutions?
Mobility is an issue that will be of great concern to all of us in the coming years. In this area trump is what brings little weight, can be produced in a resource-saving way and is easy to shape. All these requirements are met by textile carrier materials and composites. However, textiles as a pure material are still not well-known in public and in our target industries. This understanding should be promoted.

Were fashion and clothing yesterday and do hybrid product developments like your ceramic-coated high-tech fabrics represent the future? When would the company name have to be adjusted, and how long will you keep your broad range of products and services?
In any case, it is true that the textile market, especially the clothing sector, is becoming smaller and smaller in Germany, while the market for technical textile solutions is growing. Of course, this also has an impact on our business and our priorities. Textiles are now found in so many products - we would never have dreamed about before!

As far as the company name is concerned, we have discussed it extensively. We decided to keep it because it is still right. The textiles we talk about are mostly a functional material, but they still remain textiles. And the technology with which we manufacture our high-tech coatings continues to be the printing technology ...

"Without innovation no future" - In five years time, you celebrate the company’s 50th anniversary, with which fundamental corporate decisions will you then have secured the future of your customers and employees?
You already mentioned the landmark decision: "Innovation, innovation, innovation." We can secure our future through innovation only. This means that we must constantly question ourselves and be prepared to be widely interested in attending trade fairs and exhibitions and find out what people are looking for.

Innovation manager or tinkering: What does it mean for a medium-sized family business high up on the Swabian Alb having to profile on specialties in the niche? What advantages do you see compared to large companies?
The Swabian Alb is a traditional textile region. In 1980, about 30,000 people worked here in the textile industry. In 2005 it was barely a sixth. There is not much else left to do than to look for profitable niches and to show a clear profile. Perhaps the special thing about it is that we are not alone in this. Basically, all successful textile companies in our region have undergone a similar process.

As a small - and owner-managed - company, we have the shortest and fastest decision-making channels. That makes us more flexible than a big company. A budget is not questioned five times, but it is decided. If we make a trial, we can evaluate it in the evening and react the very next day. If something doesn't work, we don't need a meeting – then that's it.

At the same time, we do not automatically have a budget for research and development. We first have to carve this out elsewhere. And we do so in the knowledge that it can also be for the trash can. Within the framework of this budget, entrepreneurs have the greatest possible freedom.

To break new ground means decisiveness, overcoming fears - and thus the courage to fail. Not every project can succeed. Which entrepreneurial decision are you particularly glad to have made in retrospect? What makes you proud?
That's easy (Michael Steidle laughs)! We have realized a company’s request that has driven us for months, which in the end has also awakened personal ambition. That was the introduction to these technical coatings, the key and door opener for technical textiles in general. In doing so, I revived old resources, almost by chance. Meaning: my knowledge in electronics. That's when I realized that with a textile you can do completely different things. When you see the finished product on sale after two or three years, it makes the whole team proud!

Every man for himself, God for us all: With which sectors in the textile industry and from neighboring sectors do you want to get closer cooperation beyond competitive borders? For which higher-level problems do you consider this to be indispensable?
Actually, it is not so much a matter of competitive boundaries - cooperation with innovative competitors would always be good for the end product, but that is the case in every industry!

For us, cooperation with other companies in the textile chain is important, i.e. the upstream company. Let’s assume that I am looking for a special fabric for my coating, which in turn has to be made from a special yarn. Then I am already dependent on two companies. Fortunately, we have innovative companies right on our doorstep. But sometimes we have to go further to find the right partner. Characteristics such as willingness to take risks, a common entrepreneurial interest and a passion for the final product are enormously important in a successful cooperation.

Together with your customers, universities, specialist institutes and research institutes, porject-related you work on market-ready solutions. Do you think Germany is a good breeding ground for innovative entrepreneurs? What should happen to stay successful in international competition?
The cooperation with the institutes makes perfect sense; after all, it is their task to carry out research for companies that cannot shoulder such assignments on their own. This includes testing facilities as well as applying for funding, which is only possible in cooperation with research institutes. However, they are public institutions and therefore per se have a different objective than a company: We need to bring a promising idea to market as soon as possible so that it generates a return. A research institute does not have this pressure.

And Germany as a location? Germany is a brilliant location! But we have an infrastructure bottleneck: I mean roads and internet connections as well as access to funding or venture capital. That does not exist in Germany in the true sense anyway. Finding investors for an idea is therefore extremely difficult.

Let me give you an example: Over the years, I have received around 14,000 euros in subsidies for a coating innovation. An American entrepreneur had a very similar idea. He was able to raise about $ 35 million within three years through venture capital, crowd funding, and grants. In the end, he did not even know what he should spend the whole money on!

In addition, for us as a company in Germany, the large, open economic area of Europe is important!

You are the first textile printing company to be certified for screen printing as well as for rotary and rouleaux printing according to the GOTS standard. How important do you consider such certification as a unique selling point in the competition?
Such certifications are important because we work with clients in the upper and premium segments. Especially in times in which - undoubtedly justified - ever greater demands are placed on sustainable business and also the external presentation receives a steadily growing attention, we can support our clients this way. We therefore offer different printing methods, all of which are certified. One thing we have to be aware of is, that if we - and all the other members of the textile chain – charge the additional costs, the price mark-up would be so enormous that nobody would accept it anymore.

How do you feel about the willingness to perform of the succeeding generation? And who would you recommend to join the textile industry and to whom would you dissuade from it?
We work a lot with students and interns. Every year we give two students the opportunity to work and research in our company for their master's thesis. With these young talents, we often experience great commitment and the ambition to bring their own project to a meaningful completion. At the same time, it is difficult for us to fill our apprenticeships; the idea of working eight hours daily, five days a week seems daunting.

And who would I recommend to join the textile industry? For decades, we vehemently discouraged our offspring from working in the textile industry, because one said it has no future ... As a true high-tech industry, it is interesting for engineers, process engineers, chemists or electronic engenieers. Very important: for people with visions! If you are looking for the classic textile industry you have to be prepared to work worldwide and you will not be unemployed. Many companies are desperately looking for plant managers or managing directors for their non-European branches.

TEXTILE BASED SOLAR CELLS

Imagine a truck tarp that can harvest the energy of sunlight!

Imagine a truck tarp that can harvest the energy of sunlight!
With the help of new textile-based solar cells developed by Fraunhofer researchers, semitrailers could soon be producing the electricity needed to power cooling systems or other onboard equipment. In short, textile-based solar cells could soon be adding a whole new dimension to photovoltaics, complementing the use of conventional silicon-based solar cells. Solar panels on building roofs are a common enough sight today – as are large-scale solar parks. In the future, we may well see other surfaces being exploited for photovoltaic generation. Truck tarps, for example, could be used to produce the electricity consumed by the driver when underway or parked up for the night, or to power electronic systems used to locate trailers in shipping terminals. Similarly, conventional building facades could be covered with photovoltaic textiles in place of concrete render. Or the blinds used to provide shade in buildings with glass facades could be used to create hundreds of square meters of additional surface for producing power.

Glass-fiber fabric as a solar-cell substrate
At the heart of such visions are pliable, textile-based solar cells developed at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in collaboration with the Fraunhofer Institute for Electronic Nano Systems ENAS, Sächsisches Textilforschungsinstitut e.V and industrial partners erfal GmbH & Co. KG, PONGS Technical Textiles GmbH, Paul Rauschert GmbH & Co. KG and GILLES PLANEN GmbH. “There are a number of processes that enable solar cells to be incorporated in coatings applied to textiles,” explains Dr. Lars Rebenklau, group manager for system integration and electronic packaging at Fraunhofer IKTS. In other words, the substrate for the solar cells is a woven fabric rather than the glass or silicon conventionally used. “That might sound easy, but the machines in the textile industry are designed to handle huge rolls of fabric – five or six meters wide and up to 1000 meters in length,” explains Dr. Jonas Sundqvist, group manager for thin-film technology at Fraunhofer IKTS. “And during the coating process, the textiles have to withstand temperatures of around 200 °Celsius. Other factors play a key role too: the fabric must meet fire regulations, have a high tensile strength and be cheap to produce. “The consortium therefore opted for a glass-fiber fabric, which fulfills all of these specifications,” Rebenklau says.

An emphasis on standard processes
Researchers also faced the challenge of how to apply the wafer-thin layers that make up a solar cell – the bottom electrode, the photovoltaic layer and the top electrode – to the fabric. These layers are between one and ten microns in thickness. By comparison, the surface of the fabric is like a mountain range. The solution was first to apply a layer that levels out the peaks and troughs on the surface of the fabric. For this purpose, researchers opted for a standard process from the textile industry: transfer printing, which is also used to rubberize fabrics. All the other processes have been adapted in such a way that they can be easily incorporated in standard production methods used in the textile industry. For example, the two electrodes – which are made of electrically conductive polyester – and the photovoltaic layer are applied by means of the common roll-to-roll method. The solar cells are also laminated with an additional protective layer in order to make them more robust.

Fabric-based solar cells ready for market launch in around five years
The research team has already produced an initial prototype. “This has demonstrated the basic functionality of our textile-based solar cells,” Rebenklau says. “Right now, they have an efficiency of between 0.1 and 0.3 percent.” In a follow-up project, he and the team are seeking to push this over the five percent mark, at which point the textile-based solar cells would prove commercially viable. Silicon-based solar cells are significantly more efficient, at between ten and 20 percent. However, this new form of solar cell is not intended to replace the conventional type, merely offer an alternative for specific applications. In the coming months, the team will be investigating ways of enhancing the service life of the fabric-based solar cells. If all goes according to plan, the first textile-based solar cells could be ready for commercialization in around five years. This would fulfill the original goal of the PhotoTex project: to provide new stimulus for Germany’s textile industry and improve its competitiveness.

SUSTAINABILITY A MAJOR TOPIC AT TECHTEXTIL AND TEXPROCESS

"Sustainability at Techtextil" and "Sustainability at Texprocess" are the two topics by which these leading international trade fairs for technical textiles and non-wovens, and for the processing of textile and flexible materials, will be explicitly turning their focus for the first time onto their exhibitors' approaches to sustainability. To this will be added a broad complementary programme on this topic. Among those contributing will be major players in the industry, such as Kering, Lenzing and Zalando.

"Sustainability at Techtextil" and "Sustainability at Texprocess" are the two topics by which these leading international trade fairs for technical textiles and non-wovens, and for the processing of textile and flexible materials, will be explicitly turning their focus for the first time onto their exhibitors' approaches to sustainability. To this will be added a broad complementary programme on this topic. Among those contributing will be major players in the industry, such as Kering, Lenzing and Zalando.

Fibres made of recycled polyester, bio-based high-tech textiles, waterconserving dyeing and finishing processes, functional and work clothing, using little or no solvents and adhesives: in the field of technical textiles, and when processing textile and flexible materials, more and more firms are adopting approaches to greater sustainability. Through "Sustainability and Techtextil" and "Sustainability at Texprocess" the leading international trade fairs, from 14 to 17 May, will be demonstrating exactly these approaches taken by their exhibitors. In addition, numerous event formats will be taking up the topic of sustainability at both fairs.

Fair guide for selected exhibitors
In the run-up to Techtextil and Texprocess exhibitors at both fairs were able to submit their approaches and evidence of their work on every aspect of sustainability to the fairs' organisers. An independent, international jury of experts on sustainability assessed the submissions, in accordance with the relevance and validity of current national and international product-sustainability labels, such as currently mainly Bluesign, Cradle-to-Cradle, EU Eco Label, ISO 14001, GOTS, GRS as well as SteP by Oeko-Tex.

Overall, 47 firms were selected, including 44 exhibitors at Techtextil and three at Texprocess. Visitors who are interested will find the selected firms in their own Fair Guide, which will be available at the Fair, via filter function under "Sustainability" in the online visitor search facility, and on both fairs' apps. In addition, the exhibitors so selected will be publicizing their participation at their exhibition stands.

Members of the international jury of experts: Chairman: Max Gilgenmann, Consulting Service International Ltd. (Germany and China); Claudia Som, Empa (Switzerland); Jan Laperre, Centexbel (Belgium); Heike Illing-Günther, Textile Institute of Saxony (Sächsisches Textilinstitut e.V., Germany); Karla Magruder, Fabrikology (USA); Lauren Zahringer, SAC Social Apparel Coalition (Netherlands).

Techtextil Forum featuring theme of sustainability

EuroShop is one of those trade fairs always teeming with visual highlights. Guaranteed to present a special treat here is, of course, the Visual Merchandising Hall, the exhibition place of display mannequins and store window decorations. March 2017 will see Hall 11 of Düsseldorf Exhibition Centre (instead of Hall 4 previously), become a POS experience guaranteed to attract plenty of attention. After all, in view of the e-Commerce competition, visual marketing and the resulting emotional, personalised appearance will become more and more important for bricks-and-mortar retailers. “Consumers’ emotional needs will become the overriding theme for EuroShop,” says Andreas Gesswein, CEO of Genesis Display from Auetal, with conviction.

Display mannequins hold special emotionalising potential. It is not by chance that Düsseldorf visual artist Domagoj Mrsic once presented them as “super heroes” in one of his stagings - as Superman and Wonder Woman, Batman and Catwoman, Spiderman and Spiderwoman. Provided the displays are done well mannequins are in a way real heroes. With their appearance, their posture, gestures and mimics they can really breathe life into shop windows and in-store decorations, serve as sales-promoting tools or arouse empathy, interest and curiosity. And if they are not just headless and very abstract they even give retail stores and brands a profile and signature style. With the power of their poses they send out a clear signal as to which target group is addressed, which degree of fashion and price range is served. Moreover, when arranged in groups, they can serve as story-tellers for passers-by. Unforgettable was the “Ugly’s” line of mannequins by supplier Hans Boodt, which mimicked “real-life” men rather than V-shaped boys with six packs. It included both a long, tall one and a short, fat one dressed in passion-killing underwear. “The new generation of mannequins will say more about the brand. They will participate in communicating more about each brand’s essential values and set them apart from the competition”, says Jean-Marc Mesguich, CEO of Window France headquartered in Carros.

The portfolio offered by the display mannequin industry is wide and varied: in addition to top-model lookalikes it features plus-size beauties, Europeans, Africans and Asians, the afore-mentioned super heroes and funny common people. Kissing couples feature alongside sumo wrestlers. In line with the motto "don't take yourself too seriously", vendors have long also included dogs and cats; and even chameleons since many mannequins prove to be true artists of disguise. “Cameleon”, for example, is a patented concept of Window France: Hundreds of eyes and lips are available to chose from, eye-lashes can be glued on, wigs attached/detached, different make-ups applied or the whole face can be replaced with the help of magnets – in brief, all it takes to ensure a constantly refreshed POS appearance. Add to this what is by now a huge range of colours and materials: surfaces from velvet and rubber are just as common these days as are metallic varnishes or concrete and copper coatings.     

In view of what has been presented over the past few years you may wonder what might come next. Although the majority of fashion retailers and brands have not nearly exploited the full potential already available today. In the past few years abstract mannequins were in highest demand. “They are fit for many applications and easy to handle, since no wigs or make-up have to be styled,” says Andreas Gesswein (Genesis Display) accounting for reasons and adds: “But they are also easier to copy and therefore available in every price segment.” In practice, efficiency sometimes clearly “overrides” emotion. “But when stores do not stand out with the image they project they do not prompt shoppers to enter either,” says Jean-Marc Mesguich (Window France). And for EuroShop 2017 Window France will definitely have far more in store than “exciting variations of the abstract theme”.

Faces are back again

The fact is: just like the fashion they are wearing, display mannequins follow trends. Triggered by a desire to cut a sharper profile and stronger expression, industry insiders have seen a trend towards semi-abstract mannequins. “A face is at least alluded to. Mannequins are less neutral and it becomes visible: Retailers want to make a statement again showing their true colours. There is a trend towards addressing target groups with a more high-profile message,” explains Cornel Klugmann, Country Manager for the D-A-CH region at Hans Boodt from the Dutch city of Zwijndrecht. Monica Ceruti, in charge of PR & Communication at Almax from Mariano Comense/Italy, agrees: “It is true that demand for abstract mannequins continues to be high but there is a clear trend towards more realistic facial characteristics. This includes such details as the application of eyelashes or wigs. And dynamic postures are also getting more popular again.”

Andreas Gesswein (Genesis Display) remarks: “Especially in the luxury segment we are registering stronger demand for more realistic mannequins with faces and emotional facial expressions that brands are looking for to stand out from the rest.” A trend that Jean-Marc Mesguich (Window France) confirms: “The Haute Couture brands have already abandoned the egghead in exchange for something that will have more impact and - more importantly - get people talking about their brand.” He adds: “The growing trend of viewing fashion and fashion windows online is pushing brands to make more attractive windows and to change their displays on a more regular basis.”

The days of faceless “eggheads” seem to be over. And above and beyond this? “The look and feel is becoming more and more high-end. White and grey are replacing darker shades, glossy replaces matt and aspirational looks with more charisma are more in demand,” says Cornel Klugmann (Hans Boodt). Monica Ceruti (Almax) sees great potential in “handcrafted looks”. This means torsos with and without arms with different materials for the individual components – pedestal, torso and head – and wood as well as metallic surfaces all set the tone here. Sabrina Ciofi from Design Office La Rosa from Palazzolo Milanese/Italy summarises the “principal themes of tomorrow” as follows: “Customers demand high product quality, the right price, maximum after-sales service and high product flexibility and/or diversity.” This statement should be valid across national borders. Otherwise she says despite all the globalisation: “There are as many trends as there are markets.” Monica Ceruti (Almax) concretized: “In Europe and the USA the differences are not fundamental. In the Middle East, however, mannequins without realistic traits continue to be in demand for religious and cultural reasons. This applies especially to female display mannequins.”

Customised becomes cheaper

Producers report that the percentage of customised mannequins is generally rising. These display mannequins are individually and exclusively manufactured to customers’ specifications. In this way retail companies and brands can stand out from their competitors and consistently leverage their CI. At Hans Boodt, for example, the proportion of customised mannequins is now said to be as high as 75%. And thanks to cost-cutting process optimisation it is expected to rise even further. Like Window France these Dutch vendors have now discovered 3D printing which can serve their purposes and their buyers. While in the past prototypes used to be elaborately modelled by sculptors in clay, these can now be “printed” in a time and cost-saving manner. “On top of this, the process is even more true to life and detailed,” delights Cornel Klugmann (Hans Boodt). Graphic designers create the desired mannequins with CAD systems where all the details can be freely configured. Then the files are uploaded to the printer that puts them into practice 1:1. “We can respond to trends so much faster and at the end of the day also design more new collections each year”, Klugmann explains further benefits. Jean-Marc Mesguich (Window France) adds: “Thanks to 3D we can create mannequins that really correspond to each and every brand and every brand’s precise image, to be perfectly in-sync with their public. This is an important evolution in the role that mannequins play.”

Alongside process optimisation sustainability remains important for the sector. “The fashion sector is now highly aware of this topic and attaches importance to its suppliers also complying with the relevant criteria,” explains Monica Ceruti (Almax).   The other market players polled also share this view. For La Rosa, whose mannequins are exclusively designed and manufactured in Italy, sustainability is an integral part of quality. By their own accounts, the Italians have analysed the whole life cycle of their mannequins with a view to minimising their ecological footprint. Almost half of the polystyrene used, they say, is recycled which saves substantial amounts of crude oil and carbon dioxide emissions. On top of this, La Rosa takes back its products after use and re-introduces them into the material cycle. Production operations work with a carbon-capture system, the cooling towers use process water, energy is generated by the company’s own PV park. Andreas Gesswein (Genesis Display) also underscores the importance of this topic: “Our customers focus on trust, honesty and partnership-based cooperation. And this includes providing evidence of sustainability rather than copying other peoples’ marketing straplines. In cooperation with Dupont Tate and Lyle BioProducts we have increased the percentage of biomass in our mannequins even further over the past few years, just the same way we constantly check and optimise our materials, packaging and transport routes for sustainability.” Hans Boodt is also opting for an interesting avenue. The company currently studies whether ocean plastics could be used as a raw material for production.

EuroShop as an opportunity of the future

The display mannequin market is and will be in motion – both on the supply and demand sides. “There are customers who buy their mannequins cheaply online and others who are interested in top quality, professional consulting and holistic visual-merchandising concepts,” explain Andreas Gesswein (Genesis Display) and Cornel Klugmann (Hans Boodt). There should be no doubt about who they expect to be more successful. Andreas Gesswein: “The challenges are enormous. 2016 has been especially challenging for fashion retailers, also in Asia and the USA. Companies are faced with changed market and shopper behaviours. EuroShop 2017 will therefore probably be one of the most important ones since the fair's inception.” Jean-Marc Mesguich emphasizes: “I think that it is essential to be present at EuroShop. For both suppliers and clients. It is a sure way of exchanging views and helps pave the way forward for both parties. This year we are at a turning point in the market, so it will be even more useful for everyone.” Cornel Klugmann also recommends retail representatives to visit the trade fair: “Our innovative power is the opportunity for the future.”
