The kick-off meeting for the "Trends and Design Factors for Hydrogen Pressure Vessels" project, recently held at AZL Aachen GmbH, was a successful event, bringing together more than 37 experts in the field of composite technologies. This event laid a solid foundation for the Joint Partner Project, which currently comprises a consortium of 20 renowned companies from across the composite pressure vessel value chain: Ascend Performance Materials, C evotec GmbH, Chongqing Polycomp International Corp. (CPIC), Conbility GmbH, Elkamet Kunststofftechnik GmbH, F.A. Kümpers GmbH & Co. KG, f loteks plastik sanayi ticaret a.s., Formosa Plastics Corporation, Heraeus Noblelight GmbH, Huntsman Advanced Materials, Kaneka Belgium NV, Laserline GmbH, Mitsui Chemicals Europe GmbH, Plastik Omnium, Rassini Europe GmbH, Robert Bosch GmbH, Swancor Holding Co. Ltd. Ltd., TECNALIA, Toyota Motor Europe NV/SA, Tünkers do Brasil Ltda.

The project follows AZL´s well proven approach of a Joint Partner Project, aiming to provide technology and market insights as well as benchmarking of different material and production setups in combination with connecting experts along the value chain.

The kick-off meeting not only served as a platform to foster new contacts and get informed about the expertise and interests of the consortium members in the field of hydrogen pressure vessels, but also laid the groundwork for steering the focus of the upc oming project's ambitious phases. As a basis for the interactive discussion session, AZL outlined the background, motivation and detailed work plan. The central issues of the dialogue were the primary objectives, the most pressing challenges, the contribut ion to competitiveness, and
the priorities that would best meet the expectations of the project partners.

Discussions covered regulatory issues, the evolving value chain and the supply and properties of key materials such as carbon and glass fibres and resins. The consortium defined investigations into different manufacturing technologies, assessing their matu rity and potential benefits. Design layouts, including liners, boss designs and winding patterns, were thoroughly considered, taking into account their implications for mobile and stationary storage. The group is also interested in cost effective testing m ethods and certification processes, as well as the prospects for recycling into continuous fibres and the use of sustainable materials. Insight was requested into future demand for hydrogen tanks, OEM needs and strategies, and technological developments to produce more economical tanks.

The meeting highlighted the importance of CAE designs for fibre patterns, software suitability and the application dependent use of thermoset and thermoplastic designs.

The first report meeting will also set the stage of the next project phase, which will be the creation of reference designs by AZL's engineering team. These designs will cover a range of pressure vessel configurations using a variety of materials and production concepts. The aim is to develop models that not only re flect current technological capabilities, but also provide deep insight into the cost analysis of different production technologies, their CO₂ footprint, recycling aspects and scalability.

AZL's project remains open to additional participants. Companies interested in joining this initiative are invited to contact Philipp Fröhlig.

In cooperation with testing provider Hohenstein, Under Armour is launching a new fiber-shed test kit. It will help textile companies along the supply chain to develop lower shed materials during product development. The companies carry out the test themselves in-house using the test kit or can commission Hohenstein as a testing service provider.

The kit is a one-off purchase, after which users can buy additional materials from project partner James Heal. By using the new kit, Under Armour can reliably assess the quality and shed rate of the materials from suppliers.

For Hohenstein customers, the test kit is a useful addition to their microplastics tests. It is a quick and relatively inexpensive preliminary test that ensures better early-stage results for the end product.

During the production, wear and laundering of synthetic and natural fabrics, fibre shedding occurs in varying degrees. Hohenstein and Under Armour expect that their test method will help the industry better understand and reduce its contribution to the microfibre problem.

“Until now, integrating fiber-shed testing into industry research and development activities has required a significant time and cost investment,” said Kyle Blakely, Senior Vice President of Innovation for Under Armour. “At Under Armour, we believe intervening early to mitigate shedding is critical, which is why our test method is designed to specifically address these time and cost barriers.”

On December 7th and 8th, Bangladesh Apparel Exchange (BAE) in partnership with Fashion for Good, facilitated the “Chemical Recycling Technologies: Manufacturing Markets Gateway”, in Bangladesh. Fashion for Good, the Amsterdam based global platform for innovation, along with two disruptive technology start-ups focused on textile-to-textile chemical recycling, Circ and Infinited Fiber Company, were the key stakeholders in this initiative.

The two-day visit leveraged Bangladesh's status as a major garment production hub, exploring the potential of chemical recycling technologies to enhance environmental sustainability.

Researchers at the ITA, the University of Bonn and Heimbach GmbH have developed a new method for removing oil spills from water surfaces in an energy-saving, cost-effective way and without the use of toxic substances. The method is made possible by a technical textile that is integrated into a floating container. A single small device can remove up to 4 liters of diesel within an hour. This corresponds to about 100 m2 of oil film on a water surface.
 
Despite the steady expansion of renewable energies, global oil production, oil consumption and the risk of oil pollution have increased steadily over the last two decades. In 2022, global oil production amounted to 4.4 billion tons! Accidents often occur during the extraction, transportation and use of oil, resulting in serious and sometimes irreversible environmental pollution and harm to humans.

There are various methods for removing this oil pollution from water surfaces. However, all methods have various shortcomings that make them difficult to use and, in particular, limit the removal of oil from inland waters.

For many technical applications, unexpected solutions come from the field of biology. Millions of years of evolution led to optimized surfaces of living organisms for their interaction with the environment. Solutions - often rather unfamiliar to materials scientists and difficult to accept. The long-time routine examination of around 20,000 different species showed that there is an almost infinite variety of structures and functionalities. Some species in particular stand out for their excellent oil adsorption properties. It was shown that, e.g., leaves of the floating fern Salvinia molesta, adsorb oil, separate it from water surfaces and transport it on their surfaces (Figure 1, see also the video of the phenomon.).

The observations inspired them to transfer the effect to technical textiles for separating oil and water. The result is a superhydrophobic spacer fabric that can be produced industrially and is therefore easily scalable.

The bio-inspired textile can be integrated into a device for oil-water separation. This entire device is called a Bionic Oil Adsorber (BOA). Figure 2: Cross-section of computer-aided (CAD) model of the Bionic Oil Adsorber. The scheme shows an oil film (red) on a water surface (light blue). In the floating cotainer(gray), the textile (orange) is fixed so that it is in contact with the oil film and the end protrudes into the container. The oil is adsorbed and transported by the BOA textile. As shown in the cross-section, it enters the contain-er, where it is released again and accumulates at the bottom of the container. See also the video regarding the oil absorption on the textile, source ITA).
 
Starting from the contamination in the form of an oil film on the water surface, the separation and collection process works according to the following steps:

• The BOA is introduced into the oil film.
• The oil is adsorbed by the textile and separated from the water at the same time.
• The oil is transported through the textile into the collection container.
• The oil drips from the textile into the collection container.
• The oil is collected until the container is emptied.

The advantage of this novel oil separation device is that no additional energy has to be applied to operate the BOA. The oil is separated from the surrounding water by the surface properties of the textile and transported through the textile driven solely by capillary forces, even against gravity. When it reaches the end of the textile in the collection container, the oil desorbs without any further external influence due to gravitational forces. With the current scale approximately 4 L of diesel can be separated from water by one device of the Bionic Oil Adsorber per hour.

• It seems unlikely that a functionalized knitted spacer textile is cheaper than a conventional nonwoven, like it is commonly used for oil sorbents. However, since it is a functional material, the costs must be related to the amount of oil removed. In this respect, if we compare the sales price of the BOA textile with the sales prices of various oil-binding nonwovens, the former is 5 to 13 times cheaper with 10 ct/L oil removed.
  Overall, the BOA device offers a cost-effective and sustainable method of oil-water separation in contrast to conventional cleaning methods due to the following advantages:
• No additional energy requirements, such as with oil skimmers, are necessary
• No toxic substances are introduced into the water body, such as with oil dispersants
• The textiles and equipment can be reused multiple times
• No waste remains inside the water body
• Inexpensive in terms of the amount of oil removed.
• The team of researchers from the ITA, the University of Bonn and Heimbach GmbH was able to prove that the novel biomimetic BOA technology is surprisingly efficient and sustainable for a self-controlled separation and automatic collection of oil films including their complete removal from the water. BOA can be asapted for open water application but also for the use in inland waters. Furthermore, it is promising, that the textile can be used in various related separation processes. The product is currently being further developed so that it can be launched on the market in 2-3 years.

Recently, OETI awarded the OEKO-TEX® STeP certification to two companies in the sector of personal protective equipment (PPE) and workwear: Ötscher - Berufskleidung Götzl GmbH, Austrian producer and wholesaler and longstanding PPE and OEKO-TEX® STANDARD 100 customer, and ALSICO MOROCCO (Cindico), a Moroccan PPE and work wear producer and part of the global Alsico Group, which has already introduced the certification for production facilities in Belgium and Laos.

OEKO-TEX® STeP stands for Sustainable Textile and Leather Production and is a certification system for production facilities in the textile and leather industry. The STeP system analyses critical areas of businesses using six modules: Chemical Management, Environmental Performance, Environmental Management, Social Responsibility, Quality Management, and Health protection and Safety at work.

For ALSICO MOROCCO (Cindico), OEKO-TEX® STeP offers the benefit of "a unified certification system and standardised audits to monitor social and ecological responsibility processes at global production locations," says Managing Director Mary Meylaers.

For the Austrian company Ötscher – Berufskleidung (workwear), Managing Director Thiemo Götzl emphasises the strengths of the certification in transparent communication with customers and stakeholders and a comprehensive overview of all aspects of the supply chain. "The certification also supports compliance with the German Supply Chain Due Diligence Act requirements through transparency and risk mitigation," says Thiemo Götzl.

EURATEX welcomes the unanimous vote in support of the new rules of origin under the PEM Convention, as a historic achievement. Facilitating trade and investments in the “PanEuroMed” region (covering 27 EU member states and 24 partner countries in the neighbourhood region)¹ is top priority region for the EU, as trade with these countries accounted for €677 billion in 2023. For the EU textile and clothing sector, the region represents 35% of its exports and 21% of its imports.
 
In 2013 the European Commission adopted a package of proposals aimed at increasing trade between the European Union and neighbouring countries in the Pan-Euro-Mediterranean (PEM) region. The proposal introduced modernised rules of origin of the PEM convention, lifting the prohibition of duty-drawback and introducing the principle of “full cumulation”.

Today, after ten years of intense negotiations which EURATEX supported, the European Commission reached a full and final agreement with all PEM partners. This is a landmark achievement that will unlock the full potential of the Euro-Mediterranean area as the biggest and most integrated region of advanced manufacturing and trading of sustainable textiles and clothing. The rules adopted today will accelerate the integration of T&C supply chains and boost T&C production and trade within the region, both in the East and Southern borders of the EU. In a moment when companies are looking at moving their production from Asia to nearby, like-minded and more reliable countries , it is very timely to have the PEM Convention implemented.

EURATEX’s President, Mr Alberto Paccanelli, commented: “This is a strategic trade deal that can help European companies recover from the multiple crisis which we face since 2020”. He continued “We call on the European Union to not stop here, but keep up the efforts to secure trade deals that are good for European companies and their competitive position in the world. The next objective should be the adoption of the EU-Mercosur Agreement and a conclusive settlement of all trade disputes with the United States”.    
 
According to Director General Dirk Vantyghem, “today’s unanimous vote in favour of the modernised PEM rules is good news for our industry.. We should now engage with these partner countries to fully exploit the potential of these new rules. EURATEX is ready to engage in an industrial dialogue with the companies from the PEM Countries to facilitate their transition to the new framework”.

¹ The PanEuroMed contracting parties are: the EU, the EFTA States (Switzerland, Norway, Iceland and Liechtenstein), the Faroe Islands, the participants in the Barcelona Process (Algeria, Egypt, Israel, Jordan, Lebanon, Morocco, the territories of West Bank and Gaza, Syria, Tunisia and Turkey), the participants in the EU's Stabilisation and Association Process (Albania, Bosnia and Herzegovina, the Republic of North Macedonia, Montenegro, Serbia, Kosovo), the Republic of Moldova, Ukraine.

Faster and more cost-effective carbon fibre production - the technology of the start-up CarboScreen comes a good deal closer to this dream. The founders Dr. Musa Akdere, Felix Pohlkemper and Tim Röding from the Institut für Textiltechnik (ITA) of RWTH Aachen University are using sensor technology to monitor carbon fibre production, thereby doubling the production speed from the current 15 to 30 m/min in the medium term and increasing turnover by up to €37.5 million per year and system. This ground-breaking development also impressed the jury at the ITMF at their Annual Conference in Keqiao, China, and was honoured with the ITMF StartUp Award 2023 on 6 November 2023.

Dr. Musa Akdere accepted the award on behalf of the CarboScreen founding team.

Carbon fibres can only develop their full potential if they are not damaged during production and further processing. Two types of fibre damage occur more frequently during fibre production: Superficial or mechanical damage to the fibres or damage to the chemical structure.

Both types of damage cannot be optimally detected by current means or only become apparent after production, to name just two examples. This leads to higher production costs. In an emergency, faulty production can even lead to plant fires. For this reason, and to ensure good production quality, the system is run at 15 m/min below its production capacity for safety reasons. However, 30 m/min or more would be possible. With the sensor-based online monitoring of CarboScreen, the production capacity can be doubled to 30 /min. This would lead to higher production, resulting in lower manufacturing costs and wider use of carbon fibres in mass markets such as automotive, aerospace and wind energy.
