From the Sector

Carbon fiber-reinforced polymer lamellas are an innovative method of reinforcing buildings. There are still many unanswered questions regarding their recycling, however. A research project by Empa's Mechanical Systems Engineering lab is now set to provide answers. Thanks to the support from a foundation, the project could now be launched.

The construction sector is responsible for around 60 percent of Switzerland's annual waste. The industry's efforts to recycle demolition materials are steadily increasing. Nevertheless, there are still end-of-life materials that, for the time being, cannot be reused as recycling would be too time-consuming and expensive. One of these are carbon fiber-reinforced polymer (CFRP) lamellas.

Making buildings "live" longer
The reinforcing method developed by Urs Meier, former Empa Director at Dübendorf, has been used in infrastructure construction for 30 years. CFRP lamellas are attached with epoxy adhesive to bridges, parking garages, building walls and ceilings made of concrete or masonry. As a result, the structures can be used for 20 to 30 years longer. The method is increasingly being applied worldwide – mainly because it massively improves the earthquake resistance of masonry buildings.

"By significantly extending the lifespan of buildings and infrastructure, CFRP lamellas make an important contribution to increasing sustainability in the construction sector. However, we need to find a way how we can further use CFRP lamellas after the buildings are being demolished," explains Giovanni Terrasi, Head of the Mechanical Systems Engineering lab at Empa. To achieve this, he wants to develop a method for recycling CFRP lamellas. Convinced by this idea, a foundation supported it with a generous donation. The project officially launched in October.

Gentle separation
First, a mechanical process will be developed to detach the CFRP lamellas from the concrete without damaging them. Initial tests at Empa are encouraging: After the lamellas were separated from the concrete, they still had a strength of 95 percent – even if they had already been used for 30 years.

Then, the demolished CFRP lamellas shall be used to produce reinforcement for prefabricated components. Terrasi's goal: saving thousands of tons of CFRP lamellas from ending up in landfills after the demolition of old concrete structures and reuse them in low-CO₂ concrete elements. After completion of the project, Giovanni Terrasi and his team – consisting of Zafeirios Triantafyllidis, Valentin Ott, Mateusz Wyrzykowski and Daniel Völki – want to produce railroad sleepers from recycled concrete, which will be reinforced and prestressed with demolition CFRP lamellas. This would give the "waste-to-be" material a second life in Swiss infrastructure construction.

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.

Vietnam is the subject of increasing investment across an array of industries, with its textile sector going from strength to strength in a short space of time. To give key players from across the textile spectrum an opportunity to make their presence felt in this market, the Vietnam International Trade Fair for Apparel, Textiles and Textile Technologies (VIATT) will make its debut from 28 February – 1 March 2024. Taking place at the Saigon Exhibition and Convention Center (SECC), the new fair will cover three main product sectors, namely apparel fabrics, yarns and fibres, and garments; home textiles; as well as technical textiles and nonwovens, textile processing, and printing technology.

In line with the industry’s anticipation, the country was identified as the ideal location for ASEAN’s new comprehensive textile platform for several key reasons. Vietnam’s pro-business policies, strategic geographical location, abundant labour force, and favourable trade agreements have contributed to its rise as a global textile manufacturing hub. Agreements such as the Regional Comprehensive Economic Partnership (RCEP); the Indo-Pacific Economic Framework for Prosperity (IPEF); and 15 free trade agreements (FTAs) covering over 60 countries and regions, will further enable participants from across the value chain to conduct cross-border business after connecting at next year’s show. In addition, several key travel initiatives that serve international players have been implemented, including the country’s APEC Business Travel Card programme^[1], availability of e-visas to all nationalities, and visa-free travel for select countries^[2].  

Exhibitors from multiple textile sub-sectors converge in February
In Vietnam’s home textile segment, rising urbanisation, emerging young consumers, and higher disposable incomes are interrelated factors driving growth^[3]. Globally, three of the top trends include recycling; utilising green fibres; and the increasing use of technical fabrics for enhanced comfort and health. At the fair, confirmed home textiles exhibitors include Hanyang Eco Tex, Hohmann GmbH, Phuong Nam Feather, and SIGMA, set to showcase their most up-to-date products, covering bedding, upholstery fabrics, curtain, and sun protection.
 
Utilised for automobiles, civil aviation, construction, health care, and more, Vietnam's exports of technical textiles reached USD 676.6 million for the first nine months of 2022, up 17.1% compared to the same period in 2021^[4]. This in turn bodes well for the country’s import prospects of quality machinery and equipment. Hoping to cater to domestic demand at VIATT 2024, international suppliers in this category include Julai, SIGMA, and Skwentex.

Meanwhile, apparel-related products make up the lion’s share of the country’s textile exports – according to Vietnam Textile & Apparel Association (VITAS), in 2022 these numbered USD 29.1 billion. From Ho Chi Minh to Hanoi, numerous international fashion brands have a manufacturing presence, including Adidas, H&M, Lacoste, Lululemon, Nike, The North Face, Uniqlo, and many more. At next year’s fair, exhibitors such as Avery Dennison, Lenzing, Stylem Takisada-Osaka, and Texwinca, will aim to draw the attention of apparel brands and a wide range of other domestic and international buyers.

The Vietnam International Trade Fair for Apparel, Textiles and Textile Technologies (VIATT) is organised by Messe Frankfurt (HK) Ltd and the Vietnam Trade Promotion Agency (VIETRADE), covering the entire textile industry value chain.

The ISPO Textrends judges have selected YKK's DynaPel™ water-repellent zipper as the Best Product in the accessories category. The competition, held twice a year in conjunction with the ISPO trade show, recognizes the most innovative performance textiles, components, and apparel.

Designed to be compatible with garment recycling systems, the DynaPel™ zipper uses GTT’s EMPEL® technology instead of the standard PU film to achieve its water repellency. The lack of a PU film helps remove one of the barriers of textile-to-textile recycling of performance apparel by eliminating the urethane material, which presents challenges to garment recycling processes.

Conventional chemical and mechanical garment recycling systems cannot process the polyurethane film commonly used on water-repellent zippers, necessitating the removal of zippers from garments before recycling.  This additional processing step often deters recyclers from accepting garments with PU zippers, resulting in unnecessary waste.

EMPEL® technology uses advanced green chemistry devoid of PFAS and a specialized manufacturing process that allows the chemistry to penetrate the yarn and encapsulate it with a water-repellent layer through molecular cross-linking. The molecular cross-linking creates an extremely durable layer that is highly resistant to abrasion and invisible to the eye.

Autoneum’s sustainable, textile and lightweight Propylat technology reduces both interior and exterior noise of vehicles. Propylat was originally developed by Borgers Automotive, which was acquired by Autoneum in April 2023. The versatile technology is characterized by a flexible material composition of natural and synthetic fibers with a high recycled content and contributes to significant waste reduction thanks to its complete vertical integration. In addition, the fully recyclable technology variant Propylat PET is now part of the sustainability label Autoneum Pure.

The ongoing electrification of mobility as well as increasingly strict regulatory requirements for vehicle performance in terms of sustainability and acoustics are presenting new challenges to car manufacturers worldwide. With Propylat, Autoneum now offers another lightweight, fiber-based and versatile technology whose sound-insulating and -absorbing properties as well as high content of recycled materials help customers address these challenges. Propylat-based products not only contribute to reducing pass-by noise and improving driver comfort, but they are also up to 50 percent lighter than equivalent plastic alternatives; this results in a lower vehicle weight and, consequently, less fuel and energy consumption as well as lower CO2 emissions.

Autoneum's innovative Propylat technology consists of a mixture of recycled synthetic and natural fibers – the latter include cotton, jute, flax or hemp, for example – that are consolidated using thermoplastic binding fibers without adding any further chemical binders. Thanks to the flexible fiber composition and the variable density and thickness of the porous material, the properties of the respective Propylat variant, for example with regards to acoustic performance, can be tailored to individual customer requirements. This allows for a versatile application of the technology in a variety of interior and exterior components such as wheelhouse outer liners, trunk trim, underbody systems and carpets. For instance, Propylat-based wheelhouse outer liners significantly reduce rolling noise both inside and outside the vehicle while at the same time offering optimum protection against stone chipping and spray water.

In terms of sustainability, Propylat always contains a high proportion of recycled fibers – up to 100% in some variants – and can be manufactured with zero waste. Thanks to the full vertical integration of Propylat and Autoneum’s extensive expertise in recycling processes, the technology also contributes to a further significant reduction in production waste. Moreover, the Propylat PET technology variant, which consists of 100% PET, of which up to 70% are recycled fibers, is fully recyclable at the end of product life. For this reason, Propylat PET has been selected for Autoneum Pure – the Company’s sustainability label for technologies with excellent environmental performance throughout the product life cycle – where it will replace the current Mono-Liner technology going forward.

Propylat-based components are currently available in Europe, North America and China.
