From the Sector

The Paris 2024 Summer Olympic Games are just around the corner and a global sports frenzy is underway. However, intense summer workouts often lead to sportswear absorbing excessive sweat, becoming clingy and cumbersome, causing discomfort and potentially impacting performance. A research team from the School of Fashion and Textiles at The Hong Kong Polytechnic University (PolyU) has developed the iActive™ sportswear range which features a root-like liquid transport system and a skin-like active perspiration dissipater and utilises nature-inspired, anti-heat textile fabrics to expedite sweat removal, effectively reducing the weight and stickiness of activewear caused by sweat accumulation during exercise.

The human body has millions of sweat glands that are vital for regulating body temperature by dissipating sweat for evaporation to cool the skin’s surface. With unabating greenhouse gas emissions, the number of very hot days annually is expected to increase significantly. This will lead to elevated energy consumption and increased sweating during physical activity and outdoor labour. Even when wearing highly breathable clothes with good sweat-wicking properties, individuals may still experience discomfort due to excessive sweat accumulation.

A research team led by Dr SHOU Dahua, Limin Endowed Young Scholar in Advanced Textiles Technologies and Associate Professor of the School of Fashion and Textiles at PolyU, has invented the iActive™, intelligent, electrically activated sportswear with a nature-inspired active perspiration function.

Its nature-inspired technologies, including low-voltage-driven artificial “sweat glands” created by skin-like anti-heat textile fabrics and a root-like branching liquid transport system that aligns with the body’s sweat map, can actively and programmably remove sweat to a perspiration dissipater at the lower region of the sportswear. The all-textile sweat dissipater is compact and operates at a safe output voltage of approximately 5-9V, and its battery is easy to detach from the clothing, making it convenient for users to repeatedly wash the clothing by hand or in a washing machine to maintain hygiene. When the human body’s sweat rate is low, iActive™ can still be used independently without the battery.

Based on the optimised wettability pattern and gradient, the research team utilises a skin-like textile fabric to transport sweat one-way quickly and dissipate it from the inside to the outside. This feature reduces the stickiness and weight of clothing, improves breathability and ensures the garments remain dry and comfortable to wear. Experimental findings indicate that iActive™ creates a breathable and dry skin microclimate by dissipating sweat at a rate that is three times faster than the maximum human sweating rate. This innovation can also prevent discomfort from coldness and moisture after a workout. In comparison to traditional fabrics, the textile materials in iActive™ are 60% lighter and 50% less clingy when soaked, providing the wearer with all-round comfort and enabling sports enthusiasts and athletes to perform at their best.

Furthermore, a mobile app further aids personalised sweat management by wirelessly adjusting the sweat level of iActive™. This innovation is versatile and can be seamlessly integrated into a variety of textile materials to facilitate sustainable mass production. Beyond sportswear, iActive™ is also well-suited to protective clothing and workwear for individuals engaged in prolonged, high-intensity physical labour and outdoor occupations, including healthcare professionals, construction workers, firefighters, law enforcement officers and others, thereby significantly enhancing their work performance.

Dr Shou Dahua stated, “The extreme weather and high temperatures resulting from global warming have elevated the importance of heatstroke prevention and cooling measures on a global scale. Drawing on the vivid phenomena of thermal insulation and directed liquid flow in nature, we aim to foster innovation and sustainable advancement in garment manufacturing by inventing intelligent clothing and materials to address global challenges. We seek to harness the power of technology to infuse fresh perspectives into the traditional clothing industry, thereby enhancing its competitiveness.”

His research team has also developed a premium fabric named Omni-Cool-Dry™, drawing inspiration from volcano dwelling beetles. This fabric not only provides ultra-fast sweat dissipation and ensures all-day comfort with its dry and breathable features under dynamic thermal conditions, but also reflects solar radiation and emits body heat into the cold universe, enabling passive cooling. The team is working hard to leverage the benefits of both inventions to further enhance the sweat-dissipating and cooling capability of iActive™ sportswear.

Dr Shou Dahua, a core member of the PolyU Research Institute for Intelligent Wearable Systems and the Research Centre of Textiles for Future Fashion, has recently been bestowed with the 2023 Distinguished Achievement Award by The Fiber Society for his outstanding contributions to the fields of personal thermal and moisture management, intelligent wearables and soft robotics. The accolade is presented annually to an individual researcher worldwide. He has also received international innovation awards, including consecutive TechConnect Global Innovation Awards in 2021 and 2022. Moreover, his research papers have been published in various internationally renowned academic journals including Science Advances, PNAS, Advanced Functional Materials, and Advanced Energy Materials. Dr Shou will be chairing The Fiber Society Spring 2025 Conference at PolyU.

Das Forschungsinstitut für Textil und Bekleidung (FTB) der Hochschule Niederrhein steht seit 2009 für Forschung: von der Kompetenzplattform mit wenigen Mitarbeitenden zum eigenständigen Institut mit rund 40 Beschäftigten.
 
Die Hochschule feierte das 15-jährige Jubiläum unter dem Motto „Forschung, die anzieht!“ mit rund 150 Gäste und Partner, die den Werdegang des FTB von der Gründungszeit bis heute begleitet haben.
 
Das FTB war eines der ersten gegründeten Institute an der HSNR. Hier setzen Lehrende, Studierende und Forschende ihr Wissen in die Praxis um: Mit Hilfe der modernen Ausstattung und Maschinen bietet es optimale Bedingungen für Versuchsreihen, um an Lösungen für bestimmte Fragestellungen zu arbeiten. Themen entlang der gesamten textilen Verarbeitungskette einschließlich Recycling am Produktebensende, in die alle Lehrenden des Fachbereichs eng miteinbezogen werden, können hier umgesetzt werden. Groß geschrieben wird auch die Zusammenarbeit mit anderen Instituten und Hochschulen. Davon profitieren in besonderem Maße die Studierenden der unterschiedlichen Studiengänge wie Textil- Bekleidungstechnik, Design-Ingenieur oder Textile and Clothing Management.
 
Studierende früh an komplexe Probleme und Forschungsaufgaben heranzuführen, war immer ein Ziel der HSNR. Einen wichtigen Meilenstein erreichte der Fachbereich Anfang der 2000er Jahre mit neuen Prüfungsordnungen für Bachelor- und Masterstudiengänge in deutscher und englischer Sprache.
 
Um sich von den bisherigen Diplomstudiengängen stärker abzugrenzen, sollte die Forschung mehr Gewicht bekommen. 2009 wurde schließlich aus einer Kompetenzplattform ein eigenständiges Forschungsinstitut.
 
Die Aufnahme des FTB in das Forschungskuratorium Textil war ein Türöffner, der die Bewerbung um Forschungsprojekte bei der Industriellen Gemeinschaftsforschung (IGF) ermöglichte. Mit den ersten IGF-Projekten kamen auch der Erfolg bei anderen Förderrichtlinien und der Ausbau der Industriekooperationen.
 
Seitdem hat sich das Institut zu einer festen Größe in der Textilforschung im In- und Ausland entwickelt und beschäftigt heute rund 40 Forschende sowie in jedem Semester rund 30 Studierende.

Using bio-based and bio-degradable, recyclable insulation textiles to sustainably insulate heat and reduce energy consumption and the carbon footprint - the Aachen-based start-up SA-Dynamics has developed a solution for this dream of many building owners together with industrial partners. SA-Dynamics won the second Innovation Award in the "New Technologies on Sustainability & Recycling" category at the leading textile trade fairs Techtextil and Texprocess for this development.

The bio-based recyclable insulation textiles consist of 100 percent bio-based aerogel-fibres. They contain up to 90 percent air, trapped in the nano-pore system of the aerogel-fibres. The bio-based raw material is sustainably sourced and certified. The insulation textiles made from bio-based aerogel fibres are said to insulate the same or even better than synthetic insulating materials of fossil origin like PET, PE or PP and mineral or stone wool.

"By using bio-based aerogels, we are doing away with fossil-based materials and doing something for the environment and climate," explains Maximilian Mohr, Chief Technical Officer (CTO) at SA-Dynamics. "We are thus meeting the regulatory measures of the EU and the governments of many countries for more climate and environmental protection. By using bio-based, recyclable aerogels, we can revolutionise the world of construction.“

The Aachen-based start-up SA-Dynamics is made up of researchers from the Institut für Textiltechnik (ITA) and the Institute of Industrial Furnace Construction and Heat Engineering (IOB) at RWTH Aachen University.

The bio-based aerogel fibres originate from the LIGHT LINING research project of the BIOTEXFUTURE innovation area. The LIGHT LINING research project focussed on sports and outdoor textiles. The research results are transferable to the construction sector.

The Techtextil and Texprocess Innovation Awards ceremony will take place on 23 April 2024 at 12.30 pm in Hall 9.0 in Frankfurt/Main, Germany.

The Global Organic Textile Standard (GOTS) applauds the European Parliament's vote to ban unverified 'green' product labels by enforcing stricter rules to back green claims and labels. By obligating companies to submit evidence about environmental marketing claims – including advertising and labelling products as ‘biodegradable’, ‘less polluting’, ‘water saving’, or having ‘bio-based content’ – consumers will be able to make better informed decisions about the sustainability of their purchases.

Consumers need protection from greenwashing and false claims about a product’s environmental impact. GOTS provides rules and tools for fostering responsible business practices and to support businesses to comply with domestic and international laws and beyond. The current GOTS Version 7.0 includes rigorous criteria for the protection of human, employment and social rights, as well as the environment and climate. By being certified to GOTS 7.0 and selling GOTS-labelled goods, companies are demonstrating their commitment to sustainability and human rights.

• Combination of financial and non-financial reporting as evidence of the central role of sustainability

For this transformation to be successful, further efforts by the entire industry and a policy designed to ensure a level playing field for sustainability pioneers are needed,” says Stephan Sielaff, CEO of the Lenzing Group.

The results for the 2023 financial year were already published. The report was once again prepared in digital form and is now available.

After a long phase of continuous growth, the composites market has seen strong fluctuations since 2018. In 2023, the overall market for composites in Europe fell by 8%.

The current mood on the markets in Germany and Europe is rather negative within the industry. The main drivers are the persistently high energy and raw material prices. Added to this are problems in logistics chains and a cautious consumer climate. A slowdown in global trade and uncertainties in the political arena are fueling the negative sentiment. Despite rising registration figures, the automotive industry, the most important application area for composites, has not yet returned to its pre-2020 volume. The construction industry, the second key application area, is currently in crisis. These factors have already caused the Eu-ropean composites production volume to fall significantly in recent years. There has now been another decline in Europe for 2023.

Overall development of the composites market
The volume of the global composites market totalled 13 million tons in 2023. Compared to 2022, with a volume of 12.3 million tons, growth was around 5%. In comparison, the European composites production volume fell by 8% in 2023. The total European composites market thus comprises a volume of 2,559 kilotons (kt) after 2,781 kt in 2022.

The market is therefore declining and falling back to the level of 2014. Overall, market momentum in Europe was lower than in the global market. Europe's share of the global market is now around 20%.

As in previous years, development within Europe is not uniform. The differences are due to very different regional core markets, the high variability of the materi-als used, a wide range of different manufacturing processes and widely differing areas of application. Accordingly, there are different regional trends, especially with regard to the individual processes, although there were declines in all re-gions and for almost all processes in 2023. At almost 50% of the market volume, the transportation sector accounts for the largest share of total composites pro-duction in terms of volume. The next two largest areas are the electri-cal/electronics sector and applications in construction and infrastructure.

The Lenzing Group has updated its climate targets to align with the goals of the Paris Agreement to limit the human-induced global temperature increase to 1.5 degrees Celsius. The Science Based Targets Initiative (SBTi) has reviewed and confirmed this target improvement.

By 2030, Lenzing aims to reduce its direct emissions from the production of its fiber and pulp plants (scope 1) and its emissions from purchased energy (scope 2) by 42 percent and its indirect emissions along the value chain (scope 3) by 25 percent on the way to net zero, from 2021 baseline. This corresponds to an absolute reduction of 1,100,000 tons (instead of the previously targeted 700,000 tons).

The following targets were recognized and confirmed by the SBTi:

1. Overall net-zero target: Lenzing AG commits to reach net-zero greenhouse gas emissions along the entire value chain by 2050.
2. Near-term targets: Lenzing AG commits to reduce absolute scope 1 and scope 2 greenhouse gas emissions by 42 percent by 2030 from a base year 2021. Lenzing AG also commits to reduce absolute scope 3 greenhouse gas emissions from purchased goods and services, fuels and energy-related activities as well as upstream transport and distribution by 25 percent within the same timeframe.
3. Long-term targets: Lenzing AG commits to reduce absolute scope 1 and scope 2 greenhouse gas emissions by 90 percent by 2050 from a base year 2021. Lenzing AG also commits to reduce absolute scope 3 greenhouse gas emissions by 90 percent within in the same timeframe.

These updated targets replace the old SBTi approved Lenzing Group’s climate target in 2019.

The conference will showcase the most successful cellulose-based solutions currently on the market or those planned for the near future.

The nominees:

The Straw Flexi-Dress: Design Meets Sustainability – DITF & VRETENA (DE)
The Flexi-Dress design was inspired by the natural golden colour and silky touch of HighPerCell® (HPC) filaments based on unbleached straw pulp. These cellulose filaments are produced using environmentally friendly spinning technology in a closed-loop production process. The design decisions focused on the emotional connection and attachment to the HPC material to create a local and circular fashion product. The Flexi-Dress is designed as a versatile knitted garment – from work to street – that can be worn as a dress, but can also be split into two pieces – used separately as a top and a straight skirt. The top can also be worn with the V-neck front or back. The HPC textile knit structure was considered important for comfort and emotional properties.

Additionally, it is verified in the Product Environmental Footprint.

LENZING™ Cellulosic Fibres for Glacier Protection – Lenzing (AT)
Glaciers are now facing an unprecedented threat from global warming. Synthetic fibre-based geotextiles, while effective in slowing down glacier melt, create a new environmental challenge: microplastics contaminating glacial environments. The use of such materials contradicts the very purpose of glacier protection, as it exacerbates an already critical environmental problem. Recognizing this problem, the innovative use of cellulosic LENZING™ fibres presents a pioneering solution. The Institute of Ecology, at the University of Innsbruck, together with Lenzing and other partners made first trials in 2022 by covering small test fields with LENZING™ fibre-based geotextiles. The results were promising, confirming the effectiveness of this approach in slowing glacier melt without leaving behind microplastic.

The RENU Jacket – Advanced Recycling for Cellulosic Textiles – Pangaia (UK) & Evrnu (US)
PANGAIA LAB was born out of a dream to reduce barriers between people and the breakthrough innovations in material science. In 2023, PANGAIA LAB launched the RENU Jacket, a limited edition product made from 100% Nucycl® – a technology that recycles cellulosic textiles by breaking them down to their molecular building blocks, and reforming them into new fibres. This process produces a result that is 100% recycled and 100% recyclable when returned to the correct waste stream – maintaining the strength of the fibre so it doesn’t need to be blended with virgin material.
Through collaboration with Evrnu, the PANGAIA team created the world’s first 100% chemically recycled denim jacket, replacing a material traditionally made from 100% virgin cotton. By incorporating Nucycl® into this iconic fabric construction, dyed with natural indigo, the teams have demonstrated that it’s possible to replace ubiquitous materials with this innovation.

Textiles Made from Easy-to-dye Biocelsol – VTT Technical Research Centre of Finland (FI)
One third of the textile industry’s wastewater is generated in dyeing and one fifth in finishing. But the use of chemically modified Biocelsol fibres reduces waste water. The knitted fabric is made from viscose and Biocelsol fibres and is only dyed after knitting. This gives the Biocelsol fibres a darker shade, using the same amount of dye and no salt in dyeing process. In addition, an interesting visual effect can be achieved. Moreover, less dye is needed for the darker colour tone in the finished textile and the possibility to use the salt-free dyeing is more environmentally friendly.
These special properties of man-made cellulosic fibres will reassert the fibres as a replacement for the existing fossil-based fibres, thus filling the demand for more environmentally friendly dyeing-solutions in the textile industry. The functionalised Biocelsol fibres were made in Finnish Academy FinnCERES project and are produced by wet spinning technique from the cellulose dope containing low amounts of 3-allyloxy-2-hydroxypropyl substituents. The functionality formed is permanent and has been shown to significantly improve the dyeability of the fibres. In addition, the functionalisation of Biocelsol fibres reduces the cost of textile finishing and dyeing as well as the effluent load.

A New Generation of Bio-based and Resource-efficient Fibre – TreeToTextile (SE)
TreeToTextile has developed a unique, sustainable and resource efficient fibre that doesn't exist on the market today. It has a natural dry feel similar to cotton and a semi-dull sheen and high drape like viscose. It is based on cellulose and has the potential to complement or replace cotton, viscose and polyester as a single fibre or in blends, depending on the application.
TreeToTextile Technology™ has a low demand for chemicals, energy and water. According to a third party verified LCA, the TreeToTextile fibre has a climate impact of 0.6 kg CO2 eq/kilo fibre. The fibre is made from bio-based and traceable resources and is biodegradable.
