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.

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.

What is a Virtual Fitting Room? Advantages and Early Adopters

One of the major concerns of online shopping is a consumer’s inability to touch, feel and experience products. This concern is more problematic for fashion products, when the right fit is critical for purchase decisions. Virtual Fitting Room (VFR), a technology that allows consumers to test size and fit without having to try clothing on themselves, eases this concern.

What is a Virtual Fitting Room (VFR)?
A Virtual Fitting Room (VFR) is a function that shows and visualizes a shopper’s outfit without physically trying on and touching items. VFR utilizes Augmented Reality (AR) and Artificial Intelligence (AI). By using AR for VFR, a webcam scans the body shape of shoppers and creates a 360-degree, 3D model based on their body shape.

This concern is more problematic for fashion products, when the right fit is critical for purchase decisions. Virtual Fitting Room (VFR), a technology that allows consumers to test size and fit without having to try clothing on themselves, eases this concern.

What is a Virtual Fitting Room (VFR)?
A Virtual Fitting Room (VFR) is a function that shows and visualizes a shopper’s outfit without physically trying on and touching items. VFR utilizes Augmented Reality (AR) and Artificial Intelligence (AI). By using AR for VFR, a webcam scans the body shape of shoppers and creates a 360-degree, 3D model based on their body shape.

AI further operates VFR by using algorithms and machine learning to design a full-body 3D model of a shopper standing in front of the camera. A combination of AR and AI technology allows VFR to place items on real-time images as a live video so that customers can check the size, style and fit of the products they’re considering purchasing.

Shoppers can try on clothes and shoes at home without visiting a physical store. In order to do this, customers need to first make sure they have the right settings on their phone. Then, they download a brands’ mobile applications with the Virtual Fitting Room function or visit apparel brands’ websites that support this VFR function and upload a photo of their body shape. Some brands allow a customer to create an avatar using their body shape to test out the fashion items virtually, instead of uploading a photo of themselves.

How does using a Virtual Fitting Room benefit fashion retailers?

  • Provides a convenient shopping experience
    Research conducted by the National Retail Federation in 2020 stated that 97% of consumers have ended a shopping trip or stopped searching for the item they had in mind because the process was inconvenient.
    Shoppers surveyed not only said that in-person shopping was inconvenient but that online shopping felt even more inconvenient to them.
    VFR eliminates all of these processes. Shoppers can walk over to the VFR and see what the clothes look like quickly without needing to change them.
     
  • Overcomes the limitations of online shopping
    As of 2017, 62% of shoppers preferred to shop at physical apparel stores because they could see, touch, feel and experience products. This was a major problem that online shopping could not overcome.
    VFR solves this problem effectively. According to a Retail Perceptions Report, about 40% of buyers said they would be willing to pay more if they could experience the product through AR technology. By incorporating new technologies, VFR makes shopping fun and offers a personalized shopping experience to customers, which can attract more people to online channels.
     
  • Reduces the return rate
    High return rates are a big administrative headache for fashion brands. Moreover, it threatens to cut into the profits of fashion brands if they offer free returns. 30% of the return rate in e-commerce fashion shopping is due to purchases of small-sized products, and another 22% happens due to purchases of too large-sized products.
    However, VFR alleviates this problem. Whether in store or online, people can check the fit and size of items without having to wear them themselves.

Which brands are already using Virtual Fitting Room (VFR) technology?
Gucci

Gucci is the first luxury brand which adopted VFR. They partnered with Snapchat to launch an augmented reality shoe try-on campaign. It created a virtual lens that superimposed and overlaid a digital version of the shoe on the shopper’s foot when the foot was photographed using a cell phone camera.

Along with the Shop Now button, which guides shoppers to its online store, Gucci achieved 18.9 million Snapchat users and reported positive return on ad spend, which is a marketing metric that measures the amount of revenue earned on all dollars spent on advertising from this campaign.

Otero Menswear
Otero Menswear is a brand focused on apparel for men shorter than 5’10” (1,78 m). Otero added VFR software to its online store to provide perfect fitting sizes to its customers. First, it asks customers four quick questions about their height, leg length, waist size and body type. Then, it offers a virtual avatar corresponding with the answers. Shoppers then use this avatar to see how different sizes of Otero clothing would look on them.
 
Walmart
In May 2021, Walmart announced that they plan to acquire Zeekit, a virtual fitting room platform, to provide enhanced and social shopping experiences for customers during the pandemic.

When customers upload pictures of themselves and enter their body dimensions, Zeekit builds a virtual body and then customers can dress it accordingly. Customers will simply post their photos or choose virtual models on the platform that represent the best fitting of their height, body and skin tone. Shoppers can even share their virtual clothes with others to get various opinions. Walmart brings a comprehensive and social experience to digital shopping for customers through this acquisition of VFR.

According to research by Valuates Reports, it is expected that sales of the global virtual fitting room market will grow to $6.5 million by 2025. By adopting VFR, consumers will be able to experience convenience in an advanced shopping environment. At the same time, fashion retailers will be able to increase online sales and reduce return rates by offering customers personalized online shopping experiences using VFR technology.

New conductive, cotton-based fiber developed for smart textiles

A single strand of fiber developed at Washington State University has the flexibility of cotton and the electric conductivity of a polymer, called polyaniline.

The newly developed material showed good potential for wearable e-textiles. The WSU researchers tested the fibers with a system that powered an LED light and another that sensed ammonia gas, detailing their findings in the journal Carbohydrate Polymers.

“We have one fiber in two sections: one section is the conventional cotton: flexible and strong enough for everyday use, and the other side is the conductive material,” said Hang Liu, WSU textile researcher and the study’s corresponding author. “The cotton can support the conductive material which can provide the needed function.”

“We have one fiber in two sections: one section is the conventional cotton: flexible and strong enough for everyday use, and the other side is the conductive material,” said Hang Liu, WSU textile researcher and the study’s corresponding author. “The cotton can support the conductive material which can provide the needed function.”

While more development is needed, the idea is to integrate fibers like these into apparel as sensor patches with flexible circuits. These patches could be part of uniforms for firefighters, soldiers or workers who handle chemicals to detect for hazardous exposures. Other applications include health monitoring or exercise shirts that can do more than current fitness monitors.

“We have some smart wearables, like smart watches, that can track your movement and human vital signs, but we hope that in the future your everyday clothing can do these functions as well,” said Liu. “Fashion is not just color and style, as a lot of people think about it: fashion is science.”

In this study, the WSU team worked to overcome the challenges of mixing the conductive polymer with cotton cellulose. Polymers are substances with very large molecules that have repeating patterns. In this case, the researchers used polyaniline, also known as PANI, a synthetic polymer with conductive properties already used in applications such as printed circuit board manufacturing.

While intrinsically conductive, polyaniline is brittle and by itself, cannot be made into a fiber for textiles. To solve this, the WSU researchers dissolved cotton cellulose from recycled t-shirts into a solution and the conductive polymer into another separate solution. These two solutions were then merged together side-by-side, and the material was extruded to make one fiber.

The result showed good interfacial bonding, meaning the molecules from the different materials would stay together through stretching and bending.

Achieving the right mixture at the interface of cotton cellulose and polyaniline was a delicate balance, Liu said.

“We wanted these two solutions to work so that when the cotton and the conductive polymer contact each other they mix to a certain degree to kind of glue together, but we didn’t want them to mix too much, otherwise the conductivity would be reduced,” she said.

Additional WSU authors on this study included first author Wangcheng Liu as well as Zihui Zhao, Dan Liang, Wei-Hong Zhong and Jinwen Zhang. This research received support from the National Science Foundation and the Walmart Foundation Project.

Chemist Unlocks Plastic Alternatives Using Proteins and Clothing Scraps Photo: Challa Kumar, professor emeritus of chemistry, in his lab. (Contributed photo)

Chemist Unlocks Plastic Alternatives Using Proteins and Clothing Scraps

Challa Kumar has developed methods to create novel plastic-like materials using proteins and fabric.

Every year, 400 million tons of plastic waste are generated worldwide. Between 19 and 23 million tons of that plastic waste makes its way into aquatic ecosystems, and the remaining goes into the ground. An additional 92 million tons of cloth waste is generated annually.

Challa Kumar, professor emeritus of chemistry, “fed up” with the tremendous amount of toxic waste people continually pump into the environment, felt compelled to do something. As a chemist, doing something meant using his expertise to develop new, sustainable materials.

“Everyone should think about replacing fossil fuel-based materials with natural materials anywhere they can to help our civilization to survive,” Kumar says. “The house is on fire, we can’t wait. If the house is on fire and you start digging a well – that is not going to work. It’s time to start pouring water on the house.”

“Everyone should think about replacing fossil fuel-based materials with natural materials anywhere they can to help our civilization to survive,” Kumar says. “The house is on fire, we can’t wait. If the house is on fire and you start digging a well – that is not going to work. It’s time to start pouring water on the house.”

Kumar has developed two technologies that use proteins and cloth, respectively, to create new materials. UConn’s Technology Commercialization Services (TCS) has filed provisional patents for both technologies.

Inspired by nature’s ability to construct a diverse array of functional materials, Kumar and his team developed a method to produce continuously tunable non-toxic materials.

“Chemistry is the only thing standing in our way,” Kumar says. “If we understand protein chemistry, we can make protein materials as strong as a diamond or as soft as a feather.”

The first innovation is a process to transform naturally occurring proteins into plastic-like materials. Kumar’s student, Ankarao Kalluri ’23 Ph.D., worked on this project.

Proteins have “reactor groups” on their surfaces which can react with substances with which they come into contact. Using his knowledge of how these groups work, Kumar and his team used a chemical link to bind protein molecules together.

This process creates a dimer – a molecule composed to two proteins. From there, the dimer is joined with another dimer to create tetramer, and so on until it becomes a large 3D molecule. This 3D aspect of the technology is unique, since most synthetic polymers are linear chains.

This novel 3D structure allows the new polymer to behave like a plastic. Just like the proteins of which it is made, the material can stretch, change shape, and fold. Thus, the material can be tailored via chemistry for a variety of specific applications.

Unlike synthetic polymers, because Kumar’s material is made of proteins and a bio-linking chemical, it can biodegrade, just like plant and animal proteins do naturally.

“Nature degrades proteins by ripping apart the amide bonds that are in them,” Kumar says. “It has enzymes to handle that sort of chemistry. We have the same amide linkages in our materials. So, the same enzymes that work in biology should also work on this material and biodegrade it naturally.”

In the lab, the team found that the material degrades within a few days in acidic solution. Now, they are investigating what happens if they bury this material in the ground, which is the fate of many post-consumer plastics.

They have demonstrated that the protein-based material can form a variety of plastic-like products, including coffee cup lids and thin transparent films. It could also be used to make fire-resistant roof tiles, or higher-end materials like, car doors, rocket cone tips, or heart valves.

The next steps for this technology are to continue testing their mechanical properties, like strength or flexibility, as well as toxicity.

“I think we need to have social consciousness that we cannot put out materials into the environment that are toxic,” Kumar says. “We just cannot. We have to stop doing that. And we cannot use materials derived from fossil fuels either.”

Kumar’s second technology uses a similar principle, but instead of just proteins, uses proteins reinforced with natural fibers, specifically cotton.

“We are creating a lot of textile waste each year due to the fast-changing fashion industry” Kumar says. “So why not use that waste to create useful materials – convert waste to wealth.”

Just like the plastic-like protein materials (called “Proteios,” derived from original Greek words), Kumar expects composite materials made from proteins and natural fibers will biodegrade without producing toxic waste.

In the lab, Kumar’s former student, doctoral candidate Adekeye Damilola, created many objects with protein-fabric composites, which include small shoes, desks, flowers, and chairs. This material contains textile fibers which serve as the linking agent with the proteins, rather than the cross-linking chemical Kumar uses for the protein-based plastics.

The crosslinking provides the novel material with the strength to withstand the weight that would be put on something like a chair or a table. The natural affinity between fibers and proteins is why it’s so hard to get food stains out of clothing. This same attraction makes strong protein-fabric materials.

While Kumar’s team has only worked with cotton so far, they expect other fiber materials, like hemp fibers or jute, would behave similarly due to their inherent but common chemical properties with cotton.

“The protein naturally adheres to the surface of the protein,” Kumar says. “We used that understanding to say ‘Hey, if it binds so tightly to cotton, why don’t we make a material out of it.’ And it works, it works amazingly.”

With the support of TCS, Professor Kumar is currently seeking industry partners to bring these technologies to market. For more information contact Michael Invernale at michael.invernale@uconn.edu.

AI for safer bike helmets and better shoe soles

Researchers have trained an artificial intelligence to design the structure of so-called metamaterials with desired mechanical properties for a wide range of applications.

Researchers have trained an artificial intelligence to design the structure of so-called metamaterials with desired mechanical properties for a wide range of applications.

  • ETH researchers have used artificial intelligence to design metamaterials that show unusual or extraordinary responses to complex loads.
  • Their new AI tool deciphers the essential features of a metamaterial’s microstructure and accurately predicts its deformation behaviour.
  • The tool not only finds optimal microstructures but also bypasses time-consuming engineering simulations.

Bike helmets that absorb the energy of an impact, running shoes that give you an extra boost with every step, or implants that behave just like natural bone. Metamaterials make such applications possible. Their inner structure is the result of a careful design process, following which 3D printers produce structures with optimised properties. Researchers led by Dennis Kochmann, Professor of Mechanics and Materials in the Department of Mechanical and Process Engineering at ETH Zurich, have developed novel AI tools that bypass the time-consuming and intuition-based design process of metamaterials. Instead, they predict metamaterials with extraordinary properties in a rapid and automated fashion. A novelty, their framework applies to large (so-called non-linear) loads, e.g. when a helmet absorbs major forces during an impact.

Kochmann’s team has been among the pioneers in designing small-scale cellular structures (similar to beam networks in timber-frame houses) to create metamaterials with specific or extreme properties. “For example, we design metamaterials that behave like fluids: hard to compress but easy to deform. Or metamaterials that shrink in all directions when compressed in a particular one,” explains Kochmann.

Efficient, optimal material design
The design possibilities seem endless. However, the full potential of metamaterials is far from realised, since the design process is based on experience, involving trial and error. Furthermore, small changes in the structure can give rise to huge changes in properties.

In their recent breakthrough, the researchers succeeded in using AI to systematically explore the abundant design and mechanical properties of two types of metamaterials. Their computational tools can predict optimal structures for desired deformation responses at the push of a button. Key is the use of large datasets of the deformation behaviour of real structures to train an AI model that not only reproduces data but also generates and optimises new structures. By leveraging a method known as “variational autoencoders”, the AI learns the essential features of a structure from the large set of design parameters and how they result in specific properties. It then uses this knowledge to generate a metamaterial blueprint whenever the researchers specify its desired properties and requirements.

Assembling building blocks
Li Zheng, a doctoral student in Kochmann’s group, trained an AI model using a dataset of one million structures and their simulated response. “Imagine a huge box of Lego bricks – you can arrange them in countless ways and over time learn design principles. The AI does this extremely efficiently and learns essential design features and how to assemble the building blocks of metamaterials to give them a particular softness or hardness”, says Zheng. Unlike prior approaches using a small catalogue of building blocks as the basis for design, the new method gives the AI freedom to add, remove, or move building blocks around almost arbitrarily.  Together with Sid Kumar, an assistant professor at TU Delft and a former member of Kochmann’s team, they showed in a recently published paper that the AI model can even go beyond what it has been trained to do and predict structures that are far better than anything ever generated before.

Learning from the movies
Jan-Hendrik Bastek, also doctoral student in Kochmann’s group, used a different approach to achieve something similar. He used a method originally introduced for AI-based video generation, which has become commonplace: if you type in ‘an elephant flying over Zurich’, the AI generates a realistic video of an elephant circling the Fraumünster Church. Bastek trained his AI system using 50,000 video sequences of deforming 3D-printable structures. “I can insert the trajectory of how I want the structures to deform, and the AI produces a video of the optimal structure and the complete deformation response,” explains Bastek. Most previous approaches have focused on only predicting a single image of the optimal structure. However, giving the AI videos of the entire deformation process is crucial to retain accuracy in such complex scenarios. Based on the video sequences, the AI can create blueprints for new materials, taking into account highly complex scenarios.

Big benefits for bike helmets and shoe soles
The researchers have made available their AI tools to the metamaterials community. This will hopefully lead to the design of many new and unusual materials. The tools are opening new avenues for the development of protective equipment such as bicycle helmets and for further applications of metamaterials from medical engineering to soft robotics. Even shoe soles can be designed to absorb shocks better when running or to provide a forward boost when stepping down. Will AI completely replace the manual engineering design of materials? “No,” laughs Kochmann. “Used well, AI can be a highly efficient and diligent assistant, but it must be given the right instructions and the right training – and that requires scientific principles and engineering knowhow.”

JUMBO-Textil: "For us, leadership means team development."

With its high-quality technical narrow textiles, JUMBO-Textil stands for high-tech - whether woven, braided or knitted. As an elastic specialist and solution partner, the company develops and produces individual innovations for customers worldwide. The 70-strong team must be as diverse and flexible as the products it designs. Textination spoke to industrial engineer Carl Mrusek about the current challenges facing family businesses. Carl Mrusek, who has been Chief Sales Officer (CSO) at Textation Group GmbH & Co. KG, to which JUMBO-Textil belongs, for almost a year now, is in charge of strategic corporate development as well as other areas of responsibility.

Carl Mrusek, who has been Chief Sales Officer (CSO) at Textation Group GmbH & Co. KG, to which JUMBO-Textil belongs, for almost a year now, is in charge of strategic corporate development as well as other areas of responsibility.

 

"In a family business, tradition is the foundation, innovation is the way forward," they say. The image of family-run companies has changed significantly in recent years - old-fashioned values and outdated business concepts have given way to a strong corporate culture, a strong sense of regional responsibility and sustainable planning. How does JUMBO-Textil combine its corporate values and traditions with a contemporary management style?

Carl Mrusek: As a family business, there is a close bond between the employees and the company and vice versa; the continuity of human relationships is important and valuable. JUMBO-Textil also has a tradition of one thing in particular: contemporary corporate management, both technically and professionally, as well as in terms of management style and values. Especially in a family business, which is often managed by the same person for decades, it is crucial to question corporate values and management style and to promote change. A company that has been operating successfully internationally for almost 115 years must be adaptable. For us, reacting quickly to changes, even anticipating them and moving forward accordingly, is at the heart of smart business practices. The specialization in elastics in the 1920s is an example of the foresighted power of change, as is the strategically important turn to technical textiles in the 1970s. A recent example is the merger with vombaur under the umbrella of the Textation Group.

The most important thing in any company is its employees. We would not be able to attract and retain them with outdated traditions and working methods. For us, the focus is not on the company management, but on joint success, and in a complex world, this is usually the result of successful cooperation and not an announcement from the boss. Leadership clearly means setting and pursuing strategic goals, but today it also means team development. Finding the best people, bringing them together and motivating them to achieve the goal.

 

Team spirit and vision development: How do you achieve this at JUMBO-Textil?

Carl Mrusek: As a team! JUMBO-Textil has systematically expanded its management team. In addition to the Managing Director, our CEO Andreas Kielholz, the Chief Operational Officer Patrick Kielholz, the Chief Financial Officer Ralph Cammerath, the Chief Technology Officer Dr. Sven Schöfer and myself as Chief Sales Officer work here. This shows that we are convinced of the idea of cooperation: We also work together on corporate development and strategic issues. The same applies to the individual teams - in organizational specialist teams or in interdisciplinary project teams. The tasks for which we are responsible may be different, but each is equally important.

 

Is that why you start the introduction of contact persons on your website with the Junior Sales Manager? And the C-level representatives are at the end?

Carl Mrusek: Yes, all JUMBO-Textil heads are the head of the company for us. All JUMBO-Textil faces represent the company. This is also reflected in the order of the contact persons on the website. Visitors should be able to quickly find the person who can help them and not find out who runs the company. That's what the legal notice is for. (laughs)

 

What is JUMBO-Textil's mission statement and vision for the future, and what needs to change in order to achieve this vision?

Carl Mrusek: We are currently working on the strategic direction of the Textation Group, which JUMBO-Textil GmbH & Co. KG and vombaur GmbH & Co. KG are part of. In this context, we have developed the Group's corporate vision and mission and updated our mission statement. This serves as a foundation for strategy development and is only sustainable if employees are involved in this process through surveys and workshops. I don't want to give too much away yet, but this much is already clear: strong teams, the right people in the right place, taking responsibility at all levels, sustainability as the basis for innovation - these will be the four cornerstones. You can already see from this: To achieve our vision, we cannot flip a switch. We must always remain open to change, always new - from product development to personnel recruitment. But as I said, we have a tradition of doing this.

 

JUMBO-Textil is not an industry specialist, but combines expertise for demanding high-tech narrow textiles. Who is in charge of challenging customer projects - do you decide in a team or rather top-down, where is the responsibility for an order placed?

Carl Mrusek: As a team, we decide which projects to implement and how to prioritize them. The corporate strategy determines the "direction of travel". In addition to the sales side, the development side of new projects also plays a decisive role. I therefore coordinate intensively with Dr. Sven Schöfer (CTO) and his team, as the focus here is on the technical development and implementation of our products. In the end, project processing is always a team effort between Sales and Development in close cooperation with Production..

 

Between above-standard pay, a 4-day week and the much-vaunted work-life balance in the current situation on the job market, companies are more likely to be in the position of applicants than vice versa. What are you doing to remain attractive as an employer for new colleagues? And how do you keep the enthusiasm of your skilled employees at a consistently high level?

Carl Mrusek: An important approach for us is education. Training young people and proving to them during their apprenticeship: JUMBO-Textil is your place to be. We therefore already start recruiting skilled workers through our school visits and school internships. As a state-of-the-art company, we offer an attractive salary level and a pleasant and healthy working environment.

Applicants today also often want to organize their working hours and work arrangements individually and flexibly, for a variety of reasons. With modern working models and thanks to our ongoing progress in digitalization, we support them wherever possible. People also want to work for a company that they can identify with. Environmental and climate protection are just as important to our employees and applicants as social standards in our supply chain. The fact that we have set ourselves ambitious goals with our sustainability strategy and are consistently pursuing them with firmly scheduled steps - our climate-neutral energy generation is a concrete example that has already been implemented. Furthermore, we vigorously encourage our business partners to respect human and employee rights and are committed to the Code of Conduct of the German textile and fashion industry. All of this helps us to recruit staff.

 

What larger, more capital-intensive companies can partially make up for with financial resources, SMEs have to manage through agility and adaptability - especially in situations of crisis. To what extent are these requirements also reflected in your organizational structure and the requirements profile for employees?

Carl Mrusek: Exactly, that is the advantage that family businesses have over large corporations: We can make decisions quickly and react on a daily basis if necessary. Hierarchies are flat and coordination processes are short. An exciting suggestion doesn't have to be prepared by agencies and coordinated across several levels before it is approved by the management and can be implemented. The go-ahead can also come immediately over lunch: "Great idea, we'll do it." In a corporate group, this fails because only very few employees have the opportunity to have lunch with the management. - And we only talk about business in exceptional cases. Most of the time, the break is about family, the weather, sports and leisure plans - lunch topics, in other words. - We need responsible team players who are willing to make a change. People who work with others on an equal footing, who are committed to the company and its goals with drive and expertise and who are keen to try new things.

 

It now takes much more than a fruit basket and a gym to motivate current and potential employees. Working in a meaningful way and participating in a climate-friendly transformation is particularly important to many people. What does JUMBO-Textil do specifically to not just quote SDGs in a statement, but to live them in everyday company life?

Carl Mrusek: We have set ourselves a specific climate target: By 2035, our administrative and production operations at our headquarters will be climate-neutral. Realistic steps have been defined to achieve this. We have already achieved an important interim goal: at our headquarters in Sprockhövel, we only use green electricity from the sun, wind and water. We offset the unavoidable emissions for our heat generation with CO2 compensation services. We are also developing more and more products from recyclable and recycled materials. Our vehicle fleet is currently being converted to purely electric or hybrid models.

 

Diversification and internationalization are part of every corporate strategy these days. But what do these terms mean for the management style of a medium-sized company in Sprockhövel? Do you consciously build interdisciplinary international teams?

Carl Mrusek: We live in a hyper-diverse society. This is also reflected in our company. Our teams consist of people with different international backgrounds, without us having to actively control this. The age structure is now also very mixed. We see the different perspectives as an asset, an opportunity and a success factor. We - and that ultimately means our customers and their projects - benefit from the variety of perspectives that flow into our solutions. As with many companies in the technical textiles sector, the proportion of women in some teams is still somewhat unbalanced. However, it is fortunately increasing steadily.

 

Generational change and succession planning are core issues for family-run companies. How important is it for JUMBO-Textil to professionalize its management team and to what extent is the company open to external specialists and managers?

Carl Mrusek: A company that closes its doors to external specialists and managers is also closing a door to success. That would be foolish. At JUMBO-Textil, we try to combine and balance the close ties, personal continuity and flexibility of a family-run company, the passion and innovative spirit of a start-up and the solidity and financial strength of a group. With Patrick Kielholz as COO, the next generation of the family is represented at management level, as is the external view and the diversity of perspectives provided by the other new members at C-level. The Textation Group, which also includes Patrick Kielholz's brother Kevin Kielholz, supports the company and enables it to think and act bigger than medium-sized family businesses often do. JUMBO-Textil is an elastic specialist. And what distinguishes our product also distinguishes us as an organization. We span the advantages of a family business as well as those of a start-up and a group. If I may use the image of elasticity here and not stretch it too far. (laughs)

Wipprecht’s design was presented at Formnext, the 3D-printing event in Germany.

  • Designer Anouk Wipprecht Collaborates with Chromatic 3D Materials for a Shining, Motion-Activated Display

Chromatic 3D Materials, a 3D-printing technology company, and high-tech Dutch fashion designer Anouk Wipprecht have unveiled a new futuristic 3D-printed dress that responds to its environment through LEDs. The motion-activated design is among the first garments in the world to directly embed electronics within 3D-printed elastomers. It highlights what the future of creative expression and social interaction may look like as humankind further integrates with technology. Wipprecht’s design was presented at Formnext, the 3D-printing event in Germany.

Wipprecht’s avant-garde design highlights the potential of Chromatic’s 3D-printing technology and ChromaFlow 70™ material for commercial use. The designer used 3D printing to adhere nearly 75 flexible, 3D-printed LED domes to the fabric of the dress without adhesive or stitching. That capability could be used to create innovative running apparel, bags, footwear and other products including automotive and aerospace interiors, outdoor recreational equipment and personal protective equipment.  

The unique garment also demonstrates the flexibility of Chromatic’s materials. Unlike other 3D-printed materials, which tend to be brittle and hard, the dress features ChromaFlow 70™, a pliable, heat-resistant material that can drape and stretch more than four times its length without breaking. That flexibility makes it suitable for adding soft and seamless structural, functional and aesthetic elements that are useful for intimate and leisure apparel, sportswear, swimwear and other garments where comfort, silhouette and durability are crucial.

"Using Chromatic’s 3D materials to print offers numerous possibilities for the fashion industry. For designers like me, who incorporate electronics into our creations, it provides a unique opportunity of embedding and securing electronic parts within the printing process,“ says Anouk Wipprecht. “This is my most wearable — and washable — 3D-printed dress yet! As the electronics are enclosed, the material allows me to diffuse my LED lights, and the elastomer is both flexible and strong — making it excellent to bond to fabrics.”

“This collaboration is more than a partnership — it's a vision coming to life. By merging the genius of Anouk Wipprecht with our innovative 3D printing, we're setting the precedent for the future of fashion. We are embarking on a journey that amplifies the boundless integration of tech and art, opening doors for endless possibilities and applications in textiles and fashion,” said Cora Leibig, founder and CEO of Chromatic 3D Materials.

Checking clothing using a smartphone, AI and infrared spectroscopy

Researchers at Fraunhofer have developed an ultra-compact near-infrared spectrometer suitable for recognizing and analyzing textiles. Mixed fabrics can also be reliably identified through the combination of imaging, special AI (artificial intelligence) algorithms and spectroscopy. The technology could be used to optimize recycling old clothing, so old apparel could be sorted according to type. A highly miniaturized version of the system can even fit into a smartphone. This could lead to a host of new applications for end-users in everyday life — from checking clothes when out shopping to detecting counterfeits.

Researchers at Fraunhofer have developed an ultra-compact near-infrared spectrometer suitable for recognizing and analyzing textiles. Mixed fabrics can also be reliably identified through the combination of imaging, special AI (artificial intelligence) algorithms and spectroscopy.

This could lead to a host of new applications for end-users in everyday life — from checking clothes when out shopping to detecting counterfeits.

Infrared spectrometers are powerful measuring instruments when it comes to non-destructive analysis of organic materials. The Fraunhofer Institute for Photonic Microsystems IPMS in Dresden has recently developed a spectral analyzer system that recognizes and analyzes textile fabrics. The system can also reliably recognize mixed fabrics. Possible applications range from checking fabrics when out shopping to cleaning garments correctly, and even sustainable, sorted recycling. The spectrometer is so tiny, it can be integrated into a smartphone.

Researchers at Fraunhofer rely on near-infrared (NIR) spectroscopy to achieve the required reliability and accuracy when identifying textiles. The system works for wavelengths between 950 and 1900 nanometers, which is close to the visible spectrum. Advantages of near-infrared technology include being easy to use and having a wide range of applications. “We combine NIR spectroscopy with imaging and AI to achieve higher accuracy when recognizing and analyzing objects,” explains Dr. Heinrich Grüger, research scientist in the Sensoric Micromodules department at Fraunhofer IPMS.

How textile analysis works
Firstly, a conventional camera module captures an image of the garment. The AI selects a specific point from the fabric’s image data to be examined by the spectral analyzer module. Light reflected from the fabric is captured by the spectrometer module. There, it passes through an entrance slit, is transformed into parallel light beams using a collimating mirror and projected onto a grating using a scanning mirror. Depending on the angle of incidence and exit, the grating splits the light beams into different wavelengths. Light reflected from the grating is directed by the scanner mirror to a detector which captures the light as an electrical signal. An A/D converter then digitizes these signals, which are subsequently analyzed in the signal processor. The resulting spectrometric profile for the textile fabric reveals which fibers it is made from by comparing to a reference database.“ The optical resolution is 10 nanometers. This high resolution means the NIR spectrometer can also use AI to identify mixed fabrics such as items of clothing made from polyester and cotton,” says Grüger. Measuring just 10 mm × 10 mm and being 6.5 mm thick, the system is so compact it could easily be integrated into a standard smartphone.

Recycling old clothing
Grüger sees an important application for the AI-controlled spectrometer when it comes to recycling. According to the Federal Statistical Office of Germany, approximately 176,200 tons of textile and clothing waste was collected from private homes in Germany in 2021. NIR spectroscopy could improve recycling efficiency and reduce the mountain of old clothing. This would enable companies that recycle old clothing to sort it more efficiently and faster. Textiles that are still in one piece, for instance, go to the second-hand trade. Damaged textiles are sorted for recycling, and the fibers they are made from, such as linen, silk, cotton or lyocell, can be reused. Severely soiled textiles would be incinerated or processed into insulation mats, for example. Spectroscopic identifies and sorts textiles more accurately and much faster than a human can.

If NIR spectroscopy was to be integrated into a smartphone, end-users might also benefit from the Fraunhofer institute’s technology. When buying clothes, a quick check with a smartphone reveals whether that expensive silk scarf is genuinely made from silk, or whether that exclusive dress from the fashion label is not instead a counterfeit, exposed through an alternative mix of fabrics. And should the label with the cleaning instructions no longer be legible, the smartphone has a textile scanner to identify the fabric and so determine the appropriate wash cycle.

Food check and dermatology
Researchers at Fraunhofer IPMS can even envisage applications beyond the textile industry. Smartphones fitted with spectrometers might be used to provide information about the quality of groceries such as fruit and vegetables when out shopping. The technology might conceivably also be used to examine skin. A quick scan with the cell phone spectrometer could identify particularly dry or greasy patches. Perhaps applications in medical diagnostics might even be conceivable — examining patches of skin where a melanoma is suspected, for example — but this would need professional involvement too.

Interview with vombaur - pioneers in special textiles
Technical narrow textiles, custom solutions, medium-sized textile producer and development partner for filtration textiles, composite textiles and industrial textiles: vombaur. Digitalisation, sustainability, energy prices, pioneering work and unbroken enthusiasm – Textination spoke to two passionate textile professionals: Carl Mrusek, Chief Sales Officer (CSO), and Johannes Kauschinger, Sales Manager for Composites and Industrial Textiles, at vombaur GmbH, which, as well as JUMBO-Textil, belongs to the Textation Group.
 

Interview with vombaur - pioneers in special textiles
Technical narrow textiles, custom solutions, medium-sized textile producer and development partner for filtration textiles, composite textiles and industrial textiles: vombaur. Digitalisation, sustainability, energy prices, pioneering work and unbroken enthusiasm – Textination spoke to two passionate textile professionals: Carl Mrusek, Chief Sales Officer (CSO), and Johannes Kauschinger, Sales Manager for Composites and Industrial Textiles, at vombaur GmbH, which, as well as JUMBO-Textil, belongs to the Textation Group.
 
If you look back at your history and thus to the beginnings of the 19th century, you will see a ribbon manufactory and, from 1855, a production of silk and hat bands. Today you produce filtration textiles, industrial textiles and composites textiles. Although you still produce narrow textiles today, the motto "Transformation as an opportunity" seems to be a lived reality at vombaur.
 
Carl Mrusek, Chief Sales Officer: Yes, vombaur has changed a few times in its almost 220-year history.  Yet the company has always remained true to itself as a narrow textiles manufacturer. This testifies to the willingness of the people in the company to change and to their curiosity. Successful transformation is a joint development, there is an opportunity in change. vombaur has proven this many times over the past almost 220 years: We have adapted our product portfolio to new times, we have built new factory buildings and new machinery, we have introduced new materials and developed new technologies, we have entered into new partnerships – as most recently as part of the Textation Group. We are currently planning our new headquarters. We are not reinventing ourselves, but we will go through a kind of transformation process with the move into the brand new, climate-friendly high-tech space.

 

Could you describe the challenges of this transformation process?
 
Johannes Kauschinger, Sales Manager for Composites and Industrial Textiles: A transformation usually takes place technically, professionally, organisationally and not least – perhaps even first and foremost – culturally. The technical challenges are obvious. Secondly, in order to manage and use the new technologies, appropriate expertise is needed in the company. Thirdly, every transformation entails new processes, teams and procedures have to be adapted. And finally, fourthly, the corporate culture also changes. Technology can be procured, expertise acquired, the organisation adapted. Time, on the other hand, cannot be bought. I therefore consider the greatest challenge to be the supply of human resources: In order to actively shape the transformation and not be driven by development, we need sufficient skilled workers.

 

Visiting your website, the claim "pioneering tech tex" immediately catches the eye. Why do you see your company as a pioneer, and what are vombaur's groundbreaking or pioneering innovations?

Carl Mrusek: With our unique machine park, we are pioneers for seamless circular woven textiles. And as a development partner, we break new ground with every order. We are always implementing new project-specific changes: to the end products, to the product properties, to the machines. It happens regularly that we adapt a weaving machine for a special seamless woven shaped textile, sometimes even develop a completely new one.
 
With our young, first-class and growing team for Development and Innovation led by Dr. Sven Schöfer, we repeatedly live up to our promise of "pioneering tech tex" by developing special textile high-tech solutions with and for our customers. At the same time, we actively explore new potentials. Most recently with sustainable materials for lightweight construction and research into novel special filtration solutions, for example for the filtration of microplastics. A state-of-the-art textile technology laboratory is planned for this team in the new building.

 

The development of technical textiles in Germany is a success story. From a global perspective, we manage to succeed with mass-produced goods only in exceptional cases. How do you assess the importance of technical textiles made in Germany for the success of other, especially highly technological industries?

Carl Mrusek: We see the future of industry in Europe in individually developed high-tech products. vombaur stands for high-quality, reliable and durable products and made-to-order products. And it is precisely this – custom-fit products, instead of surplus and throwaway goods – that is the future for sustainable business in general.

 

What proportion of your production is generated by being project-based as opposed to a standard range, and to what extent do you still feel comfortable with the term "textile producer"?

Johannes Kauschinger: Our share of special solutions amounts to almost 90 percent. We develop technical textile solutions for our customers' current projects. For this purpose, we are in close contact with the colleagues from our customers' product development departments. Especially in the field of composite textiles, special solutions are in demand. This can be a component for space travel – after all, a spaceship is not manufactured off the peg. We also offer high-quality mass-produced articles, for example in the area of industrial textiles, where we offer round woven tubulars for conveyor belts. In this sense, we are a textile producer, but more than that: we are also a textile developer.

 

In August, Composites Germany presented the results of its 21st market survey. The current business situation is viewed very critically, the investment climate is becoming gloomier and future expectations are turning negative. vombaur also has high-strength textile composites made of carbon, aramid, glass and hybrids in its portfolio. Do you share the assessment of the economic situation as reflected in the survey?

Carl Mrusek: We foresee a very positive development for vombaur because we develop in a very solution-oriented way and offer our customers genuine added value. This is because future technologies in particular require individual, reliable and lightweight components. This ranges from developments for the air taxi to wind turbines. Textiles are a predestined material for the future. The challenge here is also to offer sustainable and recyclable solutions with natural raw materials such as flax and recycled and recyclable plastics and effective separation technologies.

 

There is almost no company nowadays that does not use the current buzzwords such as climate neutrality, circular economy, energy efficiency and renewable energies. What is your company doing in these areas and how do you define the importance of these approaches for commercial success?

Carl Mrusek: vombaur pursues a comprehensive sustainability strategy. Based on the development of our mission statement, we are currently working on a sustainability declaration. Our responsibility for nature will be realised in a very concrete and measurable way through our new building with a green roof and solar system. In our product development, the high sustainability standards – our own and those of our customers – are already flowing into environmentally friendly and resource-saving products and into product developments for sustainable projects such as wind farms or filtration plants.

 

Keyword digitalisation: medium-sized businesses, to which vombaur belongs with its 85 employees, are often scolded for being too reluctant in this area. How would you respond to this accusation?

Johannes Kauschinger:

We often hear about the stack crisis at the present time. Based on this, we could speak of the stack transformation. We, the small and medium-sized enterprises, are transforming ourselves in a number of different dimensions at the same time: Digital transformation, climate neutrality, skilled labour market and population development, independence from the prevailing supply chains. We are capable of change and willing to change. Politics and administration could make it a bit easier for us in some aspects. Key words: transport infrastructure, approval times, energy prices. We do everything we can on our side of the field to ensure that small and medium-sized enterprises remain the driving economic force that they are.

 

 

How do you feel about the term shortage of skilled workers? Do you also take unconventional paths to find and retain talent and skilled workers in such a specialised industry? Or does the problem not arise?

Carl Mrusek: Of course, we are also experiencing a shortage of skilled workers, especially in the industrial sector. But the development was foreseeable. The topic played a major role in the decision to move together with our sister company JUMBO-Textil under the umbrella of the Textation Group. Recruiting and promoting young talent can be better mastered together – for example with cross-group campaigns and cooperations.

 

If you had to describe a central personal experience that has shaped your attitude towards the textile industry and its future, what would it be?

Johannes Kauschinger: A very good friend of my family pointed out to me that we live in an area with a very active textile industry, which at the same time has problems finding young talents. I visited two companies for an interview and already on the tour of each company, the interaction of people, machines and textiles up to the wearable end product was truly impressive. In addition, I was able to learn a profession with a very strong connection to everyday life. To this day, I am fascinated by the wide range of possible uses for textiles, especially in technical applications, and I have no regrets whatsoever about the decision I made back then.

Carl Mrusek: I came into contact with the world of textiles and fashion at a young age. I still remember the first time I went through the fully integrated textile production of a company in Nordhorn with my father Rolf Mrusek. Since then, the subject has never left me. Even before I started my studies, I had made a conscious decision to pursue a career in this industry and to this day I have never regretted it, on the contrary. The diversity of the special solutions developed in the Textation Group fascinates me again and again.

Ananas Anam and TENCEL™ collaborate with Calvin Klein

The search for better, planet-friendly footwear material reveals a solution in one unlikely ingredient: pineapple leaves. This unique textile ingredient is the recent focus of the latest footwear design collaboration between Ananas Anam, TENCEL™ and Calvin Klein, launching Calvin Klein’s first-ever trainer featuring a knitted upper made of PIÑAYARN® blended with TENCEL™ Lyocell fibers.

Known as “The Sustainable Knit Trainer”, the trainers are a timeless closet staple, available in classic colors such as black and off-white and etched with the signature Calvin Klein logo. The PIÑAYARN® knit upper, made of 70% TENCEL™ Lyocell and 30% Anam PALF™ pineapple leaf fiber, is both from botanic origin and bio-based.

The search for better, planet-friendly footwear material reveals a solution in one unlikely ingredient: pineapple leaves. This unique textile ingredient is the recent focus of the latest footwear design collaboration between Ananas Anam, TENCEL™ and Calvin Klein, launching Calvin Klein’s first-ever trainer featuring a knitted upper made of PIÑAYARN® blended with TENCEL™ Lyocell fibers.

Known as “The Sustainable Knit Trainer”, the trainers are a timeless closet staple, available in classic colors such as black and off-white and etched with the signature Calvin Klein logo. The PIÑAYARN® knit upper, made of 70% TENCEL™ Lyocell and 30% Anam PALF™ pineapple leaf fiber, is both from botanic origin and bio-based.

As the fashion sector has begun to realize the negative environmental effects of synthetic materials, a lot of brands have turned towards plant-based materials such as PIÑAYARN®. Using a low-impact manufacturing process, PIÑAYARN® is derived from pineapple leaf waste and involves a water-free spinning process. The addition of TENCEL™ Lyocell, a fiber made from wood pulp obtained from responsibly managed forests and produced using a solvent spinning process that recycles both the solvent and water at a recovery rate of more than 99%, offers full traceability of the TENCEL™ fiber in the final blended yarn.

Melissa Braithwaite, PIÑAYARN® Product Development Manager at Ananas Anam said “The inspiration for PIÑAYARN® came from the need to provide the textile industry with an alternative to overused, often polluting, conventional fibers, such as cotton or polyester. We have an abundance of available raw material within our business, and broadening our product offering means we can valorize more waste, increasing our positive impact on the environment and society.”

Indeed, as the consumer demand for more eco-responsible textile products and footwear grows, so too has the popularity of wood-based fibers as a material alternative. Ananas Anam and TENCEL™’s collaboration with Calvin Klein has been a success in that the physical characteristics and planet-conscious benefits of both PIÑAYARN® and TENCEL™ fibers complement each other perfectly, creating a blended material that is soft and usable for various woven and knitted applications.

For material developers like Ananas Anam seeking the ideal fiber blend partner to create PIÑAYARN®, TENCEL™ Lyocellfibers are celebrated for their versatility and ability to be blended with a wide range of textiles such as hemp, linen and of course Anam PALF™ pineapple leaf fiber, to enhance the aesthetics, performance and functionality of fabrics. Additionally, beyond being used in shoe uppers, TENCEL™ Lyocell fibers can be used in every part of the shoe including the upper fabric, lining, insoles, padding, laces, zipper and sewing thread. TENCEL™ Lyocell can also be used in powder form for use in the outsoles of shoes.

“We are extremely excited about this collaboration with Ananas Anam for the launch of The Sustainable Knit Trainer by Calvin Klein, an eco-responsible and planet-friendly shoe for conscious consumers. This partnership is the perfect example of our commitment to provide education and expertise to support anyone who chooses to improve the environmental and social credentials of their products by using more responsible materials,” said Nicole Schram, Global Business Development Manager at Lenzing.

Point of View: Let’s end fast fashion

Focusing on short-term profit isn’t sustainable. So what can we do to move in the right direction: favour resilience over efficiency in all industries.

We buy cheap products knowing we’ll need to replace them soon. We throw out used items rather than repairing or re-using them. Our employers plan in terms of financial quarters despite hoping to remain relevant and resilient longer-term. Even countries prioritise short-term economic output, focusing on gross domestic product (GDP) above any other indicator.

But does this way of living, working and weighing decisions make sense in the 21st century?

Our global obsession with economic short-term efficiency – and how to transform it – is a conundrum that Professor of Sustainability Management Minna Halme has been thinking about for most of her career. Even as a business school student, she felt flummoxed by how focused her classes were on short-term goals.

Focusing on short-term profit isn’t sustainable. So what can we do to move in the right direction: favour resilience over efficiency in all industries.

We buy cheap products knowing we’ll need to replace them soon. We throw out used items rather than repairing or re-using them. Our employers plan in terms of financial quarters despite hoping to remain relevant and resilient longer-term. Even countries prioritise short-term economic output, focusing on gross domestic product (GDP) above any other indicator.

But does this way of living, working and weighing decisions make sense in the 21st century?

Our global obsession with economic short-term efficiency – and how to transform it – is a conundrum that Professor of Sustainability Management Minna Halme has been thinking about for most of her career. Even as a business school student, she felt flummoxed by how focused her classes were on short-term goals.

'It was about selling more, about maximising shareholder profits, about economic growth – but not really asking, Why? What's the purpose of all this?'

Halme says. 'Even 20-year-old me somehow just felt that this was strange.

'What are we trying to do here? Are we trying to create a better economy for all, or most, people? Whose lives are we trying to improve when we are selling more differently-packaged types of yoghurt or clothes that quickly become obsolete?'

Halme has devoted her career to studying these questions. Today, she is a thought leader in innovative business practices, with recognitions including serving on Finland's National Expert Panel for Sustainable Development and on the United Nation's Panel on Global Sustainability.

Her ultimate goal? Pioneering, researching and advocating for alternative ways of thinking that prioritise values like long-term economic sustainability and resilience – alternatives that she and other experts believe would provide more lasting, widespread benefit to all.

How traditional indicators have failed
One way in which our preference for economic efficiency shapes how we measure a country's overall well-being or status is GDP. This isn't the fault of the originator of the modern concept of GDP, who specifically warned against using it in this way in the 1930s.

'GDP was never meant to tell us about the wellbeing of the citizens of a country,' Halme says. Seventy-five years ago, however, it was easy to conflate the two. Many countries were more committed to redistributing their wealth among their citizens, and population surveys show that until the 1970s, GDP often correlated with general wellbeing.

But with the rise of increasingly heedless free-market capitalism, this became less the case – and GDP's shortcomings became all the more apparent. 'We are in a situation where the wealth distribution is more and more trickling up to those who already have capital. Those who don't have it are in declining economic positions,' Halme says. In fact, the richest 1% of the global population now own nearly half of the world's wealth.

Some governments, such as Finland's, do take indicators of environmental and social progress into account. 'But none is considered as important for decision-making as GDP,' Halme says – and GDP is also considered the arbiter of a government's success. It is that attitude that, through her work advising the Finnish government on sustainability practises as well as in her own research, Halme is trying to shift.

Where industries have failed
Our often-exclusive focus on the economy – and, in particular, on making profits as quickly and efficiently as possible – doesn’t provide a clear picture of how everyone in a society is faring. Worse yet, it has encouraged industries to act with a short-term view that makes for longer-term problems.

Fast fashion is one example. At the moment, supply chains for clothing – as for most other goods – are linear. Raw materials come from one place and are transformed step by step, usually at different factories around the world, using materials, energy and transport that are “cheap” because their high environmental costs aren’t included. They are ultimately purchased by a consumer, who wears the product temporarily before discarding it. To expand profit margins, the industry pushes fast-changing trends. A shocking amount of this clothing ends up in landfill – some of it before it's even been worn.

As the COVID lockdowns showed, this kind of linear supply system isn't resilient. Nor is it sustainable.

Currently, fashion is estimated to be the world's second most polluting industry, accounting for up to 10% of all greenhouse gas emissions. Aalto University researchers have reported that the industry produces more than 92 million tonnes of landfill waste per year. By 2030, that is expected to rise to 134 million tonnes.

Cutting fashion's carbon footprint isn't just good for the environment; it will help the longer-term prospects of the industry itself. 'With this kind of wrong thinking about efficiency, you're eroding the basis of our long-term resilience both for ecology and for society,' Halme says.

Getting out of this trap, she and other researchers say, requires a complete paradigm shift. 'It's really difficult to just tweak around the edges,' she says.

Towards resilience
For several years, Halme researched and studied ecological efficiency, looking at ways that businesses could make more products with a smaller environmental impact. But gradually she realised this wasn't the answer. Although businesses could innovate to have more efficient products and technologies, their absolute use of natural resource use kept growing.

'I began to think, "If not efficiency, then what?"' Halme says. She realised the answer was resilience: fostering ways for systems, including the environment, to continue and even regenerate in the future, rather than continuing to degrade them in the present.

The solution isn’t more of anything, even ‘sustainable’ materials. It’s less.

'The only way to fix fast fashion is to end it,' Halme and her co-authors write. This means designing clothes to last, business models that make reuse and repair more accessible, and prioritising upcycling. Recycling systems also need to be overhauled for when an item really is at the end of its life – particularly regarding blended synthetic fibres, which are difficult to separate and break down.

This would upend the current focus on short-term revenue above all else. And, says Halme, it is one more example of how we need better ways to measure the success of these industries, taking into account factors like resilience and sustainability – rather than just short-term profits.

And while individuals can make an impact, these changes ultimately have to be industry-led.

'Textiles are a good example, because if they break quickly, and if you don't have repair services nearby, or if the fabrics are of such lousy quality that it doesn't make any sense to repair them, then it's too much trouble for most people,' Halme says. 'So most solutions should come from the business side. And the attempt should be to make it both fashionable and easy for consumers to make ecologically and socially sustainable choices.'

What will it take?
The ultimate challenge, says Lauri Saarinen, Assistant Professor at the Aalto University Department of Industrial Engineering and Management, is how to shift towards a more sustainable model while keeping companies competitive. But he believes there are ways.

One option is to keep production local. 'If we compete with low-cost, offshore manufacturing by doing things more locally, and in a closed loop, then we get the double benefit of actually providing some local work and moving towards a more sustainable supply chain,' Saarinen says. For example, if clothing were produced closer to consumers, it would be easier to send garments back for repair or for brands to take back used items and resell them.

Local production is yet another example of the need to rethink how we measure societal success. After all, outsourcing and offshoring in favour of cheaper production may appear to cut costs in short term, but this is done at the expense of what Halme and other experts argue really matters – longer-term economic viability, resilience and sustainability.

Shifting towards this kind of thinking isn't easy. Still, Saarinen and Halme have seen promising signs.

In Finland, for example, Halme points to the start-up Menddie, which makes it easy and convenient to send items away for repairs or alterations. She also highlights the clothing and lifestyle brand Marimekko, which re-sells its used items in an online secondhand shop, and the Anna Ruohonen label, a made-to-measurecollection and customer on-demand concept which creates no excess garments.

It's these kinds of projects that Halme finds interesting – and that, through her work, she hopes to both advocate for and pioneer.

At the moment, she says, these changes haven't yet added up to a true transformation. On a global scale, we remain far from a genuine shift towards longer-term resilience. But as she points out, that can change quickly. After all, it has in the past. Just look at what got us here.

'The pursuit of economic growth became such a dominant focus in a relatively short time – only about seven decades,' she says. 'The shift toward longer-term resilience is certainly possible. Scientists and decision-makers just need to change their main goal to long-term resilience. The key question is, are our most powerful economic players wise enough to do so?'

As part of her research, Halme has led projects pioneering the kinds of changes that the fashion industry could adapt. For example, along with her Aalto colleague Linda Turunen, she recently developed a measurement that the fashion industry could use to classify how sustainable a product really is – measuring things like its durability, how easily it can be recycled, and whether its production uses hazardous chemicals – which could help consumers to decide whether to buy. Her colleagues curated a recent exhibition that showcased what we might be wearing in a sustainable future, such as a leather alternative made from discarded flower cuttings, or modular designs to get multiple uses from the same garment – turning a skirt into a shirt, for example.
 
Because all of this requires longer-term thinking, innovation and investment, industry is reticent to make these shifts, Halme says. One way to encourage industries to change more quickly is with regulation. In the European Union, for example, an updated set of directives now requires companies with more than 500 employees to report on a number of corporate responsibility factors, ranging from environmental impact to the treatment of employees. These rules won't just help inform consumers, investors and other stakeholders about a company's role in global challenges. They’ll also help assess investment risks – weighing whether a company is taking the actions necessary to be financially resilient in the long-term.

Wearable Connector Technology - Benefits to Military, Medicine and beyond

What comes to mind when you think about “wearable technology?” In 2023, likely a lot, at a time when smartwatches and rings measure heart rates, track exercise and even receive text messages. Your mind might even drift to that “ugly” light-up sweater or costume you saw last Halloween or holiday season.

At the Wilson College of Textiles, though, researchers are hard at work optimizing a truly new-age form of wearable technology that can be proven useful in a wide range of settings, from fashion and sports to augmented reality, the military and medicine.

Currently in its final stages, this grant-funded project could help protect users in critical situations, such as soldiers on the battlefield and patients in hospitals, while simultaneously pushing the boundaries of what textiles research can accomplish.

What comes to mind when you think about “wearable technology?” In 2023, likely a lot, at a time when smartwatches and rings measure heart rates, track exercise and even receive text messages.

At the Wilson College of Textiles, though, researchers are hard at work optimizing a truly new-age form of wearable technology that can be proven useful in a wide range of settings, from fashion and sports to augmented reality, the military and medicine.

Currently in its final stages, this grant-funded project could help protect users in critical situations, such as soldiers on the battlefield and patients in hospitals, while simultaneously pushing the boundaries of what textiles research can accomplish.

“The goals set for this research are quite novel to any other literature that exists on wearable connectors” says Shourya Dhatri Lingampally, Wilson College of Textiles graduate student and research assistant involved in the project alongside Wilson College Associate Professor Minyoung Suh.

Ongoing since the fall of 2021, Suh and Lingampally’s work focuses on textile-integrated wearable connectors, a unique, high-tech sort of “bridge” between flexible textiles and external electronic devices. At its essence, the project aims to improve these connectors’ Technology Readiness Level — a key rating used by NASA and the Department of Defense used to assess a particular technology’s maturity.

To do this, Lingampally and her colleagues’ research examines problems that have, in the past, affected the performance of wearable devices.

Sure, these advances may benefit fashion, leading to eccentric shirts, jackets, or accessories — “to light up or change its color based on the wearer’s biometric data,” Lingampally offers — the research has roots in a much deeper mission.

Potential benefits to military, medicine and beyond
The project is funded through more than $200,000 in grant money from Advanced Functional Fabrics of America (AFFOA), a United States Manufacturing Innovation Institute (MII) located in Cambridge, Massachusetts. The mission of AFFOA is to support domestic manufacturing capability to support new technical textile products, such as textile-based wearable technologies.

A key purpose of the research centers around improving the functionality of wearable monitoring devices with which soldiers are sometimes outfitted to monitor the health and safety of their troops remotely.

Similar devices allow doctors and other medical personnel to remotely monitor the health of patients even while away from the bedside.

Though such technology has existed for years, it’s too often required running wires and an overall logistically-unfriendly design. That could soon change.

“We have consolidated the electronic components into a small snap or buckle, making the circuits less obtrusive to the wearer,” Lingampally says, explaining the team’s innovations, which include 3D printing the connector prototypes using stereolithography technology.

“We are trying to optimize the design parameters in order to enhance the electrical and mechanical performance of these connectors,” she adds.

To accomplish their goals, the group collaborated with NC State Department of Electrical and Computer Engineering Assistant Research Professor James Dieffenderfer. The team routed a variety of electrical connections and interconnects like conductive thread, epoxy and solder through textile materials equipped with rigid electronic devices.

They also tested the components for compatibility with standard digital device connections like USB 2.0 and I2C.

Ultimately, Lingampally hopes their work will make wearable technology not only easier and more comfortable to use, but available at a lower price, too.

“I would like to see them scaled, to be mass manufactured, so they can be cost efficient for any industry to use,” she explains.

In a bigger-picture sense, though, her team’s work is reinforcing the far-reaching boundaries of what smart textile research can accomplish; a purpose that stretches far beyond fashion or comfort.

Pushing the boundaries of textiles research
Suh and Lingampally’s work is just the latest breakthrough research originating from the Wilson College of Textiles that’s aimed at solving critical problems in the textile industry and beyond.

“The constant advancements in technology and materials present immense potential for the textile industry to drive positive change across a range of fields from fashion to healthcare and beyond,” Lingampally, a graduate student in the M.S. Textiles program, says, noting the encouragement she feels in her program to pursue innovation and creativity in selecting and advancing her research.

Additionally, in the fiber and polymer science doctoral program, which Suh does research with, candidates focus their research on a seemingly endless array of STEM topics, ranging from forensics to medical textiles, nanotechnology and, indeed, smart wearable technology (just to name a few).

In this case, Suh says, the research lent itself to “unexpected challenges” that required intriguing adaptations “at every corner.” But, ultimately, it led to breakthroughs not previously seen in the wearable technology industry, attracting interest from other researchers outside the university, and private companies, too.

“This project was quite exploratory by nature as there hasn’t been any prior research aiming to the same objectives,” Suh says.

Meanwhile, the team has completed durability and reliability testing on its textile-integrated wearable connectors. Eventually, the group would like to increase the sample size for testing to strengthen and validate the findings. The team also hopes to evaluate new, innovative interconnective techniques, as well as other 3D printing techniques and materials as they work to further advance wearable technologies.

Ionofibres a new track for smart and functional textiles

Electronically conductive fibres are already in use in smart textiles, but in a recently published research article, ionically conductive fibres have proven to be of increasing interest. The so-called ionofibres achieve higher flexibility and durability and match the type of conduction our body uses. In the future, they may be used for such items as textile batteries, textile displays, and textile muscles.

The research project is being carried out by doctoral student Claude Huniade at the University of Borås and is a track within a larger project, Weafing, the goal of which is to develop novel, unprecedented garments for haptic stimulation comprising flexible and wearable textile actuators and sensors, including control electronics, as a new type of textile-based large area electronics.

WEAFING stands for Wearable Electroactive Fabrics Integrated in Garments. It started 1 January 2019 and ended 30 June 2023.

WEAFING stands for Wearable Electroactive Fabrics Integrated in Garments. It started 1 January 2019 and ended 30 June 2023.

These wearables are based on a new kind of textile muscles which yarns are coated with electromechanically active polymers and contract when a low voltage is applied. Textile muscles offer a completely novel and very different quality of haptic sensation, accessing also receptors of our tactile sensory system that do not react on vibration, but on soft pressure or stroke.

Furthermore, being textile materials, they offer a new way of designing and fabricating wearable haptics and can be seamlessly integrated into fabrics and garments. For these novel form of textile muscles, a huge range of possible applications in haptics is foreseen: for ergonomics, movement coaching in sports, or wellness, for enhancement of virtual or augmented reality applications in gaming or for training purposes, for inclusion of visually handicapped people by providing them information about their environment, for stress reduction or social communication, adaptive furniture, automotive industry and many more.

In Claude Huniade’s project, the goal is to produce conductive yarns without conductive metals.

"My research is about producing electrically conductive textile fibres, and ultimately yarns, by coating non-metals sustainably on commercial yarns. The biggest challenge is in the balance between keeping the textile properties and adding the conductive feature," said Claude Huniade.

Currenty, the uniqueness of his research leans towards the strategies employed when coating. These strategies expand to the processes and the materials used.

Uses ionic liquid
One of the tracks he investigates is about a new kind of material as textile coating, ionic liquids in combination with commercial textile fibres. Just like salt water, they conduct electricity but without water. Ionic liquid is a more stable electrolyte than salt water as nothing evaporates.

"The processable aspect is an important requirement since textile manufacturing can be harsh on textile fibres, especially when upscaling their use. The fibres can also be manufactured into woven or knitted without damaging them mechanically while retaining their conductivity. Surprisingly, they were even smoother to process into fabrics than the commercial yarns they are made from," explained Claude Huniade.

Ionofibres could be used as sensors since ionic liquids are sensitive to their environment. For example, humidity change can be sensed by the ionofibers, but also any stretch or pressure they are subjected to.

"Ionofibres could truly shine when they are combined with other materials or devices that require electrolytes. Ionofibres enable certain phenomena currently limited to happen in liquids to be feasible in air in a lightweight fashion. The applications are multiple and unique, for example for textile batteries, textile displays or textile muscles," said Claude Huniade.

Needs further research
Yet more research is needed to combine the ionofibres with other functional fibres and to produce the unique textile devices.

How do they stand out compared to common electronically conductive fibres?

"In comparison to electronically conductive fibres, ionofibers are different in how they conduct electricity. They are less conductive, but they bring other properties that electronically conductive fibers often lack. Ionofibres achieve higher flexibility and durability and match the type of conduction that our body uses. They actually match better than electronically conductive fibres with how electricity is present in nature," he concluded.

Innovative sportswear: Swim and run without changing

Just in time for summer: The Swiss start-up Swijin is launching a new sportswear category with its SwimRunner – a sports bra together with matching bottoms that works as both swimwear and running gear and dries in no time. The innovative product was developed together with Empa researchers in an Innosuisse project. The SwimRunner can be tested this weekend at the Zurich City Triathlon.

A quick dip after jogging without having to change clothes? Swijin (pronounced Swie-Djin), a new Swiss TechTex start-up, is launching its first product, the SwimRunner: a sports bra and bottoms that function as both swimwear and running gear and dry in a flash.

For the first time, this innovation enables women to make a smooth transition between land and water sports without having to change clothes. For example, hikers and runners can easily go into the water to cool off. Stand-up paddlers wearing the SwimRunner enjoy unrestricted freedom of movement and at the same time sufficient support, both on the board and in the water.
Science to boost sports performance
 
What appears to be a relatively simple requirement at first glance has turned out to be an extremely complex product to develop. As part of an Innosuisse project, Swijin collaborated with the Empa Biomimetic Membranes and Textiles laboratory in St. Gallen. Led by Empa engineer Martin Camenzind, the researchers first defined the requirements for the material and cut of the sports bra. "During development, we faced three main challenges: On the one hand, the product had to meet the requirements of a heavy-duty sports bra on land. At the same time, it had to maintain the compression of a swimsuit in the water – and do so with a very short drying time," says Camenzind.

Since no comparable garment exists on the market yet, the team also developed new tests for evaluating the high-performance textile. "Moreover, we designed a mannequin: a model of the female torso that can be used to measure the mechanical properties of bras," explains the researcher. In addition to scientific findings, the product development process also incorporated a great deal of expertise from sports physiologists, textile engineers, industry specialists, designers and, of course, female athletes.

Highest demands
Many of these athletes come from the swimrun scene. Swimrun is a fast-growing adventure sport that originated in the skerry gardens of Sweden. Unlike triathletes, who start out by swimming, then bike, and finally run, swimrunners switch back and forth between trail running and open water swimming throughout the race. The intensity of this sport provided Swijin with the optimal conditions for product development – and gave its name to the first collection, SwimRunner. "The feedback from female athletes was one of the deciding factors for the success of the product. They often swim and run for six to seven hours at a stretch. When they were satisfied with our prototypes, we knew: The SwimRunner is ready for market," says Swijin founder Claudia Glass.

The product idea first came to Claudia Glass while she was on vacation on Mallorca. During her morning runs, she longed to be able to take a quick dip in the sea. "Sports bras, however, are not designed for swimming," the founder explains. "They soak up the water and never seem to dry because of their thick compression material. Last summer, I wore the SwimRunner prototype all day. In the morning, I ran to Lake Zurich with my dog and jumped in. When I got back home, I could have just sat down at my desk and started working – I was completely dry and felt very comfortable."

Design and sustainability
The young company makes a point of combining engineering and design. Swijin's creative director, Valeria Cereda, is based in the center of the world's fashion capital, Milan, and infuses her experience with luxury brands into Swijin's aesthetic. But as a former competitive swimmer, she is also focused on functionality.

Swijin's high-performance products can only be realized with synthetic materials. The young company is determined to reduce the environmental impact of its products to a minimum. The tight supply chain keeps the CO2 footprint low. The materials of the SwimRunner are 100% made in the EU and designed for quality.

Traditional garment labels only provide information about where the garment was made. Swijin is working with supplier Avery Dennison to provide all products with a Digital Identity Label. This gives consumers detailed information about the entire value chain, right down to the textile manufacturer's investment in reducing its carbon footprint and the use of the water-based, solvent-free logo. Swijin packages all materials in Cradle-to-Cradle Gold certified packaging, which is produced by Voegeli AG in Emmental.

Furthermore, Swijin proactively addresses the challenges at the end of the product life cycle. In order to come one step closer to a truly circular economy for functional textiles, Swijin participates in the Yarn-to-Yarn® pilot project of Rheiazymes AG as a lighthouse partner. This biotech solution uses microorganisms and enzymes to generate new starting materials directly from used textiles in a climate-neutral way. When customers return end-of-life Swijin products – for which the company offers incentives – the high-quality monomers can be returned to the supply chain in their original quality: true circularity.

"As an emerging brand, we have both the obligation and the luxury of choosing partners whose vision and values align with our own," says Claudia Glass. "I had a clear understanding of what kind of brand I would buy, but I couldn't find it anywhere. With Swijin, we feel obligated to actually make our values a reality."

The impact of textile production and waste on the environment

  • With fast fashion, the quantity of clothes produced and thrown away has boomed.

Fast fashion is the constant provision of new styles at very low prices. To tackle the impact on the environment, the EU wants to reduce textile waste and increase the life cycle and recycling of textiles. This is part of the plan to achieve a circular economy by 2050.

Overconsumption of natural resources
It takes a lot of water to produce textile, plus land to grow cotton and other fibres. It is estimated that the global textile and clothing industry used 79 billion cubic metres of water in 2015, while the needs of the EU's whole economy amounted to 266 billion cubic metres in 2017.

To make a single cotton t-shirt, 2,700 litres of fresh water are required according to estimates, enough to meet one person’s drinking needs for 2.5 years.

Fast fashion is the constant provision of new styles at very low prices. To tackle the impact on the environment, the EU wants to reduce textile waste and increase the life cycle and recycling of textiles. This is part of the plan to achieve a circular economy by 2050.

To make a single cotton t-shirt, 2,700 litres of fresh water are required according to estimates, enough to meet one person’s drinking needs for 2.5 years.

The textile sector was the third largest source of water degradation and land use in 2020. In that year, it took on average nine cubic metres of water, 400 square metres of land and 391 kilogrammes (kg) of raw materials to provide clothes and shoes for each EU citizen.

Water pollution
Textile production is estimated to be responsible for about 20% of global clean water pollution from dyeing and finishing products.

Laundering synthetic clothes accounts for 35% of primary microplastics released into the environment. A single laundry load of polyester clothes can discharge 700,000 microplastic fibres that can end up in the food chain.

The majority of microplastics from textiles are released during the first few washes. Fast fashion is based on mass production, low prices and high sales volumes that promotes many first washes.

Washing synthetic products has caused more than 14 million tonnes of microplastics to accumulate on the bottom of the oceans. In addition to this global problem, the pollution generated by garment production has a devastating impact on the health of local people, animals and ecosystems where the factories are located.

Greenhouse gas emissions
The fashion industry is estimated to be responsible for 10% of global carbon emissions – more than international flights and maritime shipping combined.

According to the European Environment Agency, textile purchases in the EU in 2020 generated about 270 kg of CO2 emissions per person. That means textile products consumed in the EU generated greenhouse gas emissions of 121 million tonnes.

Textile waste in landfills and low recycling rates
The way people get rid of unwanted clothes has also changed, with items being thrown away rather than donated. Less than half of used clothes are collected for reuse or recycling, and only 1% of used clothes are recycled into new clothes, since technologies that would enable clothes to be recycled into virgin fibres are only now starting to emerge.

Between 2000 and 2015, clothing production doubled, while the average use of an item of clothing has decreased.

Europeans use nearly 26 kilos of textiles and discard about 11 kilos of them every year. Used clothes can be exported outside the EU, but are mostly (87%) incinerated or landfilled.

The rise of fast fashion has been crucial in the increase in consumption, driven partly by social media and the industry bringing fashion trends to more consumers at a faster pace than in the past.

The new strategies to tackle this issue include developing new business models for clothing rental, designing products in a way that would make re-use and recycling easier (circular fashion), convincing consumers to buy fewer clothes of better quality (slow fashion) and generally steering consumer behaviour towards more sustainable options.

Work in progress: the EU strategy for sustainable and circular textiles
As part of the circular economy action plan, the European Commission presented in March 2022 a new strategy to make textiles more durable, repairable, reusable and recyclable, tackle fast fashion and stimulate innovation within the sector.

The new strategy includes new ecodesign requirements for textiles, clearer information, a Digital Product Passport and calls companies to take responsibility and act to minimise their carbon and environmental footprints

On 1 June 2023, MEPs set out proposals for tougher EU measures to halt the excessive production and consumption of textiles. Parliament’s report calls for textiles to be produced respecting human, social and labour rights, as well as the environment and animal welfare.

Existing EU measures to tackle textile waste
Under the waste directive approved by the Parliament in 2018, EU countries are obliged to collect textiles separately by 2025. The new Commission strategy also includes measures to, tackle the presence of hazardous chemicals, calls producers have to take responsibility for their products along the value chain, including when they become wasteand help consumers to choose sustainable textiles.

The EU has an EU Ecolabel that producers respecting ecological criteria can apply to items, ensuring a limited use of harmful substances and reduced water and air pollution.

The EU has also introduced some measures to mitigate the impact of textile waste on the environment. Horizon 2020 funds Resyntex, a project using chemical recycling, which could provide a circular economy business model for the textile industry.

A more sustainable model of textile production also has the potential to boost the economy. "Europe finds itself in an unprecedented health and economic crisis, revealing the fragility of our global supply chains," said lead MEP Huitema. "Stimulating new innovative business models will in turn create new economic growth and the job opportunities Europe will need to recover."

Soundwaves to separate microplastics from wastewater

The technology developed by The Hong Kong Research Institute of Textiles and Apparel (HKRITA) with the support of H&M Foundation, can separate microplastics from wastewater using soundwaves. Acousweep is a plug-and-play application. The technology can be easily transported and connected to any wastewater facility. If the technology is implemented at an industrial scale, it will have a significant impact on the fashion industry’s sustainable footprint.

Acousweep is a plug-and-play application. The technology can be easily transported and connected to any wastewater facility. If the technology is implemented at an industrial scale, it will have a significant impact on the fashion industry’s sustainable footprint.
 
Microplastic pollution is a globally established problem and a threat to ecosystems, animals, and people. Microplastics come from a variety of sources, including from larger plastic debris that degrades into smaller and smaller pieces, or microbeads in exfoliating health and beauty products, or cleansers such as toothpaste. According to the European Environment Agency the major source of oceanic microplastic pollution, about 16%-35% globally, comes from synthetic textiles. Professor Christine Loh, Chief Development Strategist at the Institute for the Environment, The Hong Kong University of Science and Technology, agrees that this technology has great potential.

Microplastics typically refers to tiny plastic pieces or particles smaller than 5mm in diameter according to the definition of United Nations Environment Programme (UNEP) and the European Union (EU). The new technology can separate microplastic fibre longer than 20 μm, which is 250 times smaller than the typical size. Unlike existing filtration processes, the system enables continuous water treatment and easy collection of microplastic fibres by virtue of its acoustic manipulation technique.

Acousweep utilises sweeping acoustic waves in a specially shaped chamber to physically trap and separate microplastic fibres from wastewater effectively. The whole process is merely a physical collection and separation. No chemical, solvent or biological additives are needed. The separated microplastics drip into a collection tank for further treatment, such as recycling. Acousweep, with a developing lab-scale treatment system of the capacity of 100L of water per hour, can be upscaled in industrial plants. The system can be installed in a container with a processing capacity up to 5-10T per hour. The containerised system can be easily transported and connected to the existing sewage outlets of the wastewater treatment system.
 
Process of Microplastic Fibre Separation:

  1. At one end of the chamber is a transducer that generates a sweeping acoustic wave at ultrasound frequencies. At the other end, there is a reflector, inside which sweeping acoustic waves are reflected and forms standing waves.
  2. When standing waves are applied to the particles in a fluid, an acoustic radiation force traps the particles.
  3. The standing waves then transfer the trapped particles to the reflector side; after that, particles concentrate at the apex of the reflector.
  4. At the apex is a needle valve which is controlled by a sensory system that monitors the concentration of microplastic fibres there. When the concentration is sufficiently high, the sensory system opens the needle valve to let the microplastic fibres drip into a collection tank.
  5. A high temperature can be applied to the collection tank to remove the water, leaving the fibres to agglomerate and form a large mass that can be easily dealt with in future treatment.

Green tech has just taken a leap forward in Hong Kong. Acousweep will help the garment and other industries to stop a highly damaging form of pollution. HKRITA used a new technique to remove the microplastics by using soundwave-based system, preventing them from getting into the sea and being ingested by sea life that can even be ingested by humans along the food chain. Acousweep has the capacity to revolutionize industry, says Professor Christine Loh, Chief Development Strategist at the Institute for the Environment, The Hong Kong University of Science and Technology.

Cheaper method for making woven displays and smart fabrics

Researchers have developed next-generation smart textiles – incorporating LEDs, sensors, energy harvesting, and storage – that can be produced inexpensively, in any shape or size, using conventional industrial looms used to make the clothing worn every day.
 
An international team, led by the University of Cambridge, have previously demonstrated that woven displays can be made at large sizes, but these earlier examples were made using specialised manual laboratory equipment. Other smart textiles can be manufactured in specialised microelectronic fabrication facilities, but these are highly expensive and produce large volumes of waste.

Researchers have developed next-generation smart textiles – incorporating LEDs, sensors, energy harvesting, and storage – that can be produced inexpensively, in any shape or size, using conventional industrial looms used to make the clothing worn every day.
 
An international team, led by the University of Cambridge, have previously demonstrated that woven displays can be made at large sizes, but these earlier examples were made using specialised manual laboratory equipment. Other smart textiles can be manufactured in specialised microelectronic fabrication facilities, but these are highly expensive and produce large volumes of waste.

However, the team found that flexible displays and smart fabrics can be made much more cheaply, and more sustainably, by weaving electronic, optoelectronic, sensing and energy fibre components on the same industrial looms used to make conventional textiles. Their results, reported in the journal Science Advances, demonstrate how smart textiles could be an alternative to larger electronics in sectors including automotive, electronics, fashion and construction.

Despite recent progress in the development of smart textiles, their functionality, dimensions and shapes have been limited by current manufacturing processes.
“We could make these textiles in specialised microelectronics facilities, but these require billions of pounds of investment,” said Dr Sanghyo Lee from Cambridge’s Department of Engineering, the paper’s first author. “In addition, manufacturing smart textiles in this way is highly limited, since everything has to be made on the same rigid wafers used to make integrated circuits, so the maximum size we can get is about 30 centimetres in diameter.”

“Smart textiles have also been limited by their lack of practicality,” said Dr Luigi Occhipinti, also from the Department of Engineering, who co-led the research. “You think of the sort of bending, stretching and folding that normal fabrics have to withstand, and it’s been a challenge to incorporate that same durability into smart textiles.”
Last year, some of the same researchers showed that if the fibres used in smart textiles were coated with materials that can withstand stretching, they could be compatible with conventional weaving processes. Using this technique, they produced a 46-inch woven demonstrator display.

Now, the researchers have shown that smart textiles can be made using automated processes, with no limits on their size or shape. Multiple types of fibre devices, including energy storage devices, light-emitting diodes, and transistors were fabricated, encapsulated, and mixed with conventional fibres, either synthetic or natural, to build smart textiles by automated weaving. The fibre devices were interconnected by an automated laser welding method with electrically conductive adhesive.
 
The processes were all optimised to minimise damage to the electronic components, which in turn made the smart textiles durable enough to withstand the stretching of an industrial weaving machine. The encapsulation method was developed to consider the functionality of the fibre devices, and the mechanical force and thermal energy were investigated systematically to achieve automated weaving and laser-based interconnection, respectively.

The research team, working in partnership with textile manufacturers, were able to produce test patches of smart textiles of roughly 50x50 centimetres, although this can be scaled up to larger dimensions and produced in large volumes.
 
“These companies have well-established manufacturing lines with high throughput fibre extruders and large weaving machines that can weave a metre square of textiles automatically,” said Lee. “So when we introduce the smart fibres to the process, the result is basically an electronic system that is manufactured exactly the same way other textiles are manufactured.”
The researchers say it could be possible for large, flexible displays and monitors to be made on industrial looms, rather than in specialised electronics manufacturing facilities, which would make them far cheaper to produce. Further optimisation of the process is needed, however.

“The flexibility of these textiles is absolutely amazing,” said Occhipinti. “Not just in terms of their mechanical flexibility, but the flexibility of the approach, and to deploy sustainable and eco-friendly electronics manufacturing platforms that contribute to the reduction of carbon emissions and enable real applications of smart textiles in buildings, car interiors and clothing. Our approach is quite unique in that way.”

The research was supported in part by the European Union and UK Research and Innovation.

Prior to the conference, the conference advisory board had nominated six remarkable innovations. The winners were elected in an exciting head-to-head live-voting by the conference audience on the first day of the event.

The collaboration between Nanollose (AU) and Birla Cellulose (IN) with tree-free lyocell from bacterial cellulose called Nullarbor™ is the winning cellulose fibre innovation 2023, followed by Renewcell (SE) cellulose fibres made from 100 % textile waste, while Vybrana – the new generation banana fibre from Gencrest Bio Products (IN) won third place.
    
Winner: Nullarbor™ – Nanollose and Birla Cellulose (AU/IN)
In 2020, Nanollose and Birla Cellulose started a journey to develop and commercialize treefree lyocell from bacterial cellulose, called Nullarbor™. The name derives from the Latin “nulla arbor” which means “no trees”. Initial lab research at both ends led to the joint patent application “production of high-tenacity lyocell fibres made from bacterial cellulose”.
Nullarbor is significantly stronger than lyocell made from wood-based pulp; even adding small amounts of bacterial cellulose to wood pulp increases the fibre toughness. In 2022, the first pilot batch of 260 kg was produced with 20 % bacterial pulp share. Several high-quality fabrics and garments were produced with this fibre. The collaboration between Nanollose and Birla Cellulose now focuses on increasing the production scale and amount of bacterial pulp in the fibre.  

Second place: Circulose® – makes fashion circular – Renewcell (SE)
Circulose® made by Renewcell is a branded dissolving pulp made from 100 % textile waste, like worn-out clothes and production scraps. It provides a unique material for fashion that is 100 % recycled, recyclable, biodegradable, and of virgin-equivalent quality. It is used by fibre producers to make staple fibre or filaments like viscose, lyocell, modal, acetate or other types of man-made cellulosic fibres. In 2022, Renewcell, opened the world’s first textile-to-textile     
chemical recycling plant in Sundsvall, Sweden – Renewcell 1. The plant is expected to reach an annual capacity of 120,000 tonnes.

Third place: Vybrana – The new generation banana fibre – Gencrest Bio Products (IN)
Vybrana is a Gencrest’s Sustainable Cellulosic Fibre upcycled from agrowaste. Raw fibres are extracted from the banana stem at the end of the plant lifecycle. The biomass waste is then treated by the Gencrest patented Fiberzyme technology. Here, cocktail enzyme formulations remove the high lignin content and other impurities and help fibre fibrillation. The company's proprietary cottonisation process provides fine, spinnable cellulose staple fibres suitable for blending with other staple fibres and can be spun on any conventional spinning systems giving yarns sustainable apparel. Vybrana is produced without the use of heavy chemicals and minimized water consumption and in a waste-free process where balance biomass is converted to bio stimulants Agrosatva and bio-based fertilizers and organic manure.

PVH owns brands such as Calvin Klein and Tommy Hilfiger. In the agreement signed by PVH Corp, the company commits to accelerating the textile industry's transition to a circular economy through its participation in the consortium.

Carbios is working with On, Patagonia, PUMA, PVH Corp. and Salomon to test and improve its bio-recycling technology on their products. The aim is to demonstrate that this process closes the fibre-to-fibre loop on an industrial scale, in line with sustainability commitments.

The two-year cooperation project will not only enable the biological recycling of polyester articles on an industrial scale, but also develop thorough sorting and disassembly technologies for complex textile waste. Existing members voted unanimously for PVH Corp. to join the consortium, saying the common goal is to support the development of viable solutions that address the fashion industry's contribution to climate change..

Carbios has developed a technology using highly selective enzymes that can recycle mixed feedstocks, reducing the laborious sorting required by current thermomechanical recycling processes. For textiles made from blended fibres, the patented enzyme acts only on the PET polyester contained within. This innovative process produces recycled PET (r-PET) that is equivalent in quality to virgin PET and can be used to produce new textile fibres.

Textile waste treatment and recycling
Globally, only 13% of textile waste is currently recycled, mainly for low-value applications such as upholstery, insulation or rags. The remaining 87% is destined for landfill or incineration. To work on improving textile recycling technologies, consortium members will supply feedstock in the form of clothing, underwear, footwear and sportswear. In 2023, a new PET textile waste facility will be commissioned at the Carbios demonstration plant, notably as part of the LIFE Cycle of PET project co-funded by the European Union.  This is in anticipation of future regulations, such as the separate collection of textile waste, which will be mandatory in Europe from 1 January 2025.

From fibre to fibre: circularity of textiles
Today, the textile industry relies largely on non-renewable resources to produce fibres and fabrics, partly turning to recycled PET bottles for recycled polyester fibres. However, this resource will become scarce as PET bottles are used exclusively for the production of new bottles in the food and beverage industry. In a circular economy, the materials used to produce textiles are obtained from recycled or renewable raw materials produced by regenerative processes. In addition to supplying raw materials for the demonstration plant, the consortium members also aim to produce new products from r-PET fibres using the company's biorecycling process.

"Partnering with Carbios and its consortium members demonstrates our continued commitment to incorporating more circular materials into our collections," said Esther Verburg, EVP, Sustainable Business and Innovation, Tommy Hilfiger Global and PVH Europe. "We are excited to support the development of Carbios' enzymatic recycling technology and to leverage new solutions that can help us drive fashion sustainably."

6 out of 10 consumers pay attention to sustainability criteria when shopping

ESG aspects are most important to consumers when it comes to food and clothing. Young people in particular demand information and transparency: sustainability labels, certifications and reports ensure trust. For retailers and manufacturers, sustainability is becoming a must.

Under what conditions are the cows kept whose milk I drink? Does the manufacturer of my new T-shirt tolerate child labor? Does the retailer I trust deal fairly with employees and business partners? The majority of Germans ask themselves questions like these before making a purchasing decision. When shopping, 59 percent of consumers always or at least frequently pay attention to the ecological, economic or social sustainability of retailers and manufacturers. Among those under 35, the figure is even hugher with two-thirds, and among those over 55, one in two. These are the findings of a representative survey of 1,000 people in Germany commissioned by the auditing and consulting firm PwC Germany.

When shopping, 59 percent of consumers always or at least frequently pay attention to the ecological, economic or social sustainability of retailers and manufacturers. Among those under 35, the figure is even hugher with two-thirds, and among those over 55, one in two. These are the findings of a representative survey of 1,000 people in Germany commissioned by the auditing and consulting firm PwC Germany.

Sustainability is no longer a question of "if", but "how".
"Sustainability has become mainstream in recent years. For companies, paying attention to sustainability in their supply chains has already become a must," comments Dr. Christian Wulff. The Head of Retail and Consumer Goods at PwC Germany is convinced that companies will already have to give good reasons in the near future if they do not pay attention to the environment, social aspects and good corporate governance when producing a product. "The issue of sustainability is therefore no longer a question of whether, but of how," the retail expert continues.

Sustainability includes various aspects in the three areas of environment, social and sustainable governance (ESG). In the case of environmental sustainability, the focus is on issues relating to animal welfare - such as the conditions in which animals are kept or animal testing - and the use of recyclable materials. 40 percent of Germans would like to be informed about this before making a purchase. In the social sphere, the majority of respondents would like to know whether retailers and manufacturers comply with human rights (58 percent) - for example, whether they tolerate forced or child labor in their value chains. In terms of governance, one in two respondents would like to know about supply chains and be able to trace products before making a purchase.

Sustainability is particularly important for food
How closely consumers look at sustainability also depends on the product: For example, sustainability is particularly important to them when it comes to food. 81 percent of Germans pay attention to at least one of the three ESG criteria when buying food, i.e. environment, social issues or good corporate governance. But these criteria are also relevant when buying textiles: As many as 63 percent say they look at how sustainably the item was produced when buying clothing or shoes. While environmental aspects play the biggest role for food (62 percent), consumers are paying more attention to social aspects for clothing, shoes and accessories (52 percent).

Almost every second person has recently switched to sustainable products
The growing importance of ESG aspects in the purchasing behavior of German consumers is also evidenced by the shifts toward buying sustainable products. The trend toward sustainable products is clearest in the case of food: 45 percent of respondents state that they have consciously switched to more sustainable products within the past two years. By contrast, only 17 percent admit to switching (back) to less sustainable products, with one in three stating a lack of financial resources as the reason.

For just under half of those surveyed, a possible switch to more sustainable products would be supported by better availability in stationary retail. Legal regulations are also seen as helpful, both in terms of product labeling (38 percent) and for the production process (37 percent). More eye-catching product placement in stores would also help (37 percent).

Young people in particular demand transparency and education
Consumers' need for transparency in ESG matters is significant: According to the survey, almost three quarters of Germans obtain information about environmental sustainability issues at least occasionally. Two-thirds research aspects of social sustainability. A good half regularly find out about sustainable corporate governance.

Age has a major influence on how intensively people deal with the issue: While 80 percent of 16- to 24-year-olds find out about the environmental aspects of a product before buying it, only 59 percent of those over 65 do. "Younger people in particular are actively informing themselves and demanding transparency around ESG criteria," sums up Christian Wulff.

Consumers want information on packaging and online
To meet this need for information, the PwC expert advises manufacturers and retailers to provide detailed information about ESG aspects of products, especially online. "Keeping the associated, significantly increasing flood of data up to date at all times is increasingly becoming a challenge for companies that can only be solved by significant investments in new technologies."

Consumers agree on what companies can do to lend more credibility to their sustainability activities: A solid two-thirds consider recognized sustainability labels, certifications or independently audited sustainability reports to be suitable for credibly communicating activities in terms of ESG. "The results of our survey show that labels and independent certifications are very important in gaining the trust of customers. It is therefore worthwhile to have ESG measures confirmed by external organizations," says Christian Wulff.

Retailers and manufacturers should focus on transparency
"Manufacturers and retailers are faced with the task of ensuring a high level of transparency with regard to the sustainability of their products. This calls for honesty, but also creativity: In the case of fashion, for example, it is conceivable to trace the individual stages of the supply chain in detail and to show the costs incurred in the process. In this way, consumers can understand exactly how a price comes about," concludes Christian Wulff.
