From the Sector

STFI will be presenting high-end textile products and solutions at Techtextil 2024. The highlights from current research results and innovations provide an insight into the digitalisation of textile production, show applications for 3D printing and smart technical textiles and provide examples of particularly sustainably designed products as well as innovative approaches for protective and medical textiles.

The central highlight of STFI's presence at Techtextil is a robot system that demonstrates the automated processing of a bobbin frame on a small scale. The pick-and-place application demonstrates camera-supported gripping of the bobbins. The robot is part of the STFI's “Textile Factory of the Future” which demonstrates automation solutions for the textile industry in a laboratory environment.

From the field of sustainable products and solutions, a sleeping bag with bio-based and therefore vegan filling material and a natural fibre-based composite element for furniture construction, in which LEDs and capacitive proximity sensors for contactless function control have been applied using embroidery technology, will be on show. Printed heating conductor structures demonstrate current research work for the e-mobility of the future, as the individually controllable seat and interior heating should ultimately reduce weight and save energy compared to conventional heating systems.

While a protective suit for special task forces protects against the dangers of a Molotov cocktail attack, a shin guard and a knee brace with patellar ring illustrate the process combination of 3D printing and UV LED cross-linking. Other highlights from lightweight textile construction include the rib of a vertical rudder of an Airbus A320 and a green snowboard made from recycled carbon fibres.

Ahead of the extra-ordinary Council on 6 October in Granada, EURATEX President, Alberto Paccanelli, and CIE President, Jose Vte Serna, call on the EU Presidency to develop a new competitiveness strategy, which can relaunch the European industry and ensure it will remain competitive in the decades to come. This means bringing together trade, energy, state aid and sustainability policies into a single, integrated, comprehensive approach, which can support a robust and modern European manufacturing industry.  
 
To consolidate a strong industrial structure in Europe, the Union should

1. secure the supply of clean energy at a competitive cost;
2. support innovation and foster the necessary talent pool and
3. be more assertive in achieving an international level-playing field on sustainability, based on the European model.  

During the past few years the implementation of incoherent and conflicting objectives under the trade, energy, industrial and sustainability policy has been observed. As a matter of fact, while the circular economy promised to be a recipe for a competitive industry of the future, the likelihood of pushing the EU industry out of the market and driving investment elsewhere than in Europe is very high. If this approach were to continue in the next years, it will result in a de-industrialised Europe, depending on imports from abroad. Such a Europe would be more exposed to geopolitical turmoil, with no agency to deliver its vision of peace, well-being and a healthy environment to its citizens.

It is fundamental for Europe to pursue a more coherent set of policies that put the competitiveness of its domestic industry at the core. In this context, all the industrial manufacturing sectors should be in the scope, including the textile industry, given its importance in providing essential products and applications to our society. A first impactful action that can be taken in this direction, would be to expand the scope of the Net-Zero Industry Act (NZIA) to include the textiles and clothing industry.
 
The history of European industry is fully woven in the birth and expansion of the European textiles industry since the XVIII century. Still today, the European textiles and clothing industry holds a pivotal position in the market, encompassing a diverse range of sectors and applications. In terms of employment, our industry creates 1,3 million direct jobs in Europe, encompassing a wide range of roles, from design and production to distribution and retail. European textiles have a wide range of applications, the most common one is of course clothing and fashion. The industry has a long history of producing high-quality apparel, with various regions specializing in specific niches.
 
Beyond clothing, there is a wide range of industrial sectors were textiles play an essential role, including  Automotive (used for upholstery, interior components, and even lightweight composite materials), Aircraft and Shipbuilding (where textiles are employed for their lightweight and high-strength properties, to enhance fuel efficiency, reduce emissions, and improve overall performance), Building and Construction (insulation, roofing, geotextiles, and architectural textiles), or Personal Protective Equipment, for medical personnel, firefighters, police and army officers. This includes masks, gowns, uniforms, helmets, and fire-resistant clothing, ensuring safety in hazardous environments.
 
Textiles are essential components of our society and our well-being. It is key for Europe to maintain its capacity to manufacture high-quality, sustainable and high-technology textiles.  With this in mind, the competitiveness policy of the future and the related funds to support it, should include the textile ecosystem in its scope.  

Society and the economy are facing existential challenges. In addition to the consequences of climate change, these include the realisation that energy and many resources are no longer available in the usual quantities, so that their efficiency must be significantly increased in the short term. Lightweight construction, especially with fibre composite materials, can and will make an important contribution here, e.g. in wind power plants or hydrogen storage systems. As an umbrella organisation, Composites Germany represents the capabilities and interests of the German fibre composite industry. With the re-entry of Composites United, Composites Germany will combine the forces of the two leading composites networks in Germany and its position will be significantly strengthened. Changed framework conditions make the re-entry possible and necessary.

VDMA and Leichtbau BW will continue to support the work of Composites Germany as associate members and contribute the know-how of their members. Together, the organisations will promote sustainable lightweight construction as a key technology for Germany, focusing on composites materials, says Prof. Klaus Drechsler of Composites United, one of the two board members of Composites Germany. As a network and mouthpiece of the composites industry, Composites Germany bundles the interests of its members. The aim is to continuously expand activities, promote innovations and technologies, develop new markets and new value chains, and anchor training and further education, adds his board colleague Dr Michael Effing of AVK. The agreement was concluded on 29 November 2022 during the JEC Forum DACH in Augsburg, where both associations were cooperation partners of the event.

The European Pultrusion Technology Association (EPTA) has published a report from its latest conference, which focuses on advances in sustainability and recycling.

More than 130 professionals from the global pultrusion community gathered at the 16th World Pultrusion Conference in Paris on 5-6 May 2022. Organised by EPTA in collaboration with the American Composites Manufacturers Association (ACMA), the event featured 25 international speakers sharing insight on market trends, developments in materials, processing and simulation technologies, and innovative pultruded applications in key markets such as building and infrastructure, transportation and wind energy.

‘Bio-pultrusion’:  
Composites based on natural fibres offer a number of benefits, including low density and high specific strength, vibration damping, and heat insulation. The German Institutes for Textile and Fiber Research Denkendorf (DITF) are developing pultrusion processes using bio-based resins and natural fibres. Projects include the BioMat Pavilion at the University of Stuttgart, a lightweight structure which combines ‘bamboo-like’ natural fibre-based pultruded profiles with a tensile membrane.

Applications for recycled carbon fibre (rCF):
The use of rCF in composite components has the potential to reduce their cost and carbon footprint. However, it is currently used to a limited extent since manufacturers are uncertain about the technical performance of available rCF products, how to process them, and the actual benefits achievable. Fraunhofer IGCV is partnering with the Institute for Textile Technology (ITA) in the MAI ÖkoCaP project to investigate the technical, ecological and economic benefits of using rCF in different industrial applications. The results will be made available in a web-based app.

Circularity and recycling:
The European Composites Industry Association (EuCIA) is drafting a circularity roadmap for the composites industry. It has collaborated with the European Cement Association (CEMBUREAU) on a position paper for the EU Commission’s Joint Research Centre (JRC) which outlines the benefits of co-processing end-of-life composites in cement manufacturing, a recycling solution that is compliant with the EU’s Waste Framework Directive and in commercial operation in Germany. Initial studies have indicated that co-processing with composites has the potential to reduce the global warming impact of cement manufacture by up to 16%. Technologies to allow recovery of fibre and/or resin from composites are in development but a better understanding of the life cycle assessment (LCA) impact of these processes is essential. EuCIA’s ‘circularity waterfall,’ a proposed priority system for composites circularity, highlights the continued need for co-processing.

Sustainability along the value chain:
Sustainability is essential for the long-term viability of businesses. Resin manufacturer AOC’s actions to improve sustainability include programmes to reduce energy, waste and greenhouse gas emissions from operations, the development of ‘greener’ and low VOC emission resins, ensuring compliance with chemicals legislation such as REACH, and involvement in EuCIA’s waste management initiatives. Its sustainable resins portfolio includes styrene-free and low-styrene formulations and products manufactured using bio-based raw materials and recycled PET.

The H160 was designed by Airbus Helicopters to create added value for customers in terms of performance, economic competitiveness, safety and comfort. The use of Hexcel’s composite materials throughout the structure (fuselage, tail boom, tail rotor and main rotor blades) contributes to the lightweight fuel-saving design and performance optimization.
“Hexcel’s composite materials have been used in Airbus Helicopters’ programs for many years and we are honored to be continuing our long term relationship, based on innovation and continuous improvement” commented Thierry Merlot, Hexcel President Aerospace EMEA-AP. “We thank Airbus Helicopters for their selection and look forward to our ongoing supply of high performance, weight saving composites materials for this innovative rotorcraft”.
H160 configurations in development include offshore transportation, business and private aviation, emergency medical services, public services, and commercial passenger transport. The helicopter is planned to enter into service in 2019.
