From the Sector

Rieter has stood for pioneering innovation in textile technology for 230 years. Founded in 1795, the company has grown from a trading company to a global technology leader. With a clear focus on automation, digitization and sustainability, Rieter is shaping the future of yarn production and continues to set standards in the industry.

Rieter, a world leader in developing and manufacturing systems for yarn production with staple fibers, is celebrating its 230th anniversary this year – a history characterized by change, innovation and growth.

The Rieter success story began on April 15, 1795, when Johann Jacob Rieter founded the company J.J. Rieter & Cie. in Winterthur, Switzerland. Rieter started as a trading company for exotic spices and cotton, and on April 23, 1795, the first cotton bale had already arrived at the Waaghaus trading house on Marktgasse in Winterthur.

Initially involved in spinning mills and textile manufacturing, Rieter continued to develop over the 19th century and shifted its focus to building industrial machinery. Acquiring the buildings of the former Töss Abbey in Winterthur in 1833 was an important step. In addition to spinning mill machines, the company’s product line also included machines for winding, knitting, and weaving.

In 1891, Rieter converted into a stock company, which was a significant milestone in the company’s history. In the decades that followed, Rieter set new technological standards again and again. For example, the company was the first machine factory in Switzerland with electronic data processing and Rieter set up a modern laboratory for testing materials. It was joined by prototype workshops, a textile laboratory, and a test spinning mill to support further innovation.

Despite economic challenges, Rieter has always used times of crisis as an opportunity to increase its efficiency and hone its strategic focus. Along with its subsidiaries Accotex, Bräcker, Graf, Novibra, Suessen, SSM, and Temco, today Rieter is distinctive and well-known in the market. The company is a leader in spinning mill technology and contributes to sustainability in the textile value chain with state-of-the-art machines, systems, and components.

Rieter’s success is based not only on technological excellence, but above all on the people who drive the company forward. The approximately 4 800 employees worldwide are the company’s greatest asset. With their expertise, innovative spirit, and passion, they set new standards every day and play an active role in shaping Rieter’s future.

From Rieter’s perspective, the future of spinning mills is automated, digital, and intelligent. Research and development activities are being intensified – in both the areas of autonomous transport systems and collaborative robotics, as well as for ESSENTIAL, Rieter’s digital spinning mill platform. The goal is to fully automate the value creation process of spinning mills by 2027. This will enable spinning mills to reduce their yarn manufacturing costs and maximize their returns. Customers can then concentrate fully on their yarn business and rely on Rieter’s technology and know-how for their operations.

With 230 years of experience, strong innovative power, sustainable solutions and a global sales and service organization, Rieter looks to the future with confidence.

Fibre-reinforced pressure vessels are increasingly becoming the cornerstone of the hydrogen economy, playing a key role in the transport, storage and use of hydrogen for both mobile and stationary applications. AZL Aachen GmbH, in collaboration with a consortium of 25 leading industry players, has successfully completed a 12-month R&D project entitled 'Trends & Design Factors for Hydrogen Pressure Vessels'.

The 550-pages report, presented to the 40 participants of the final project meeting in November, provides a comprehensive overview of the market and technology trends related to the development of thermoset and thermoplastic pressure vessels. By addressing material impacts, complex design considerations and advanced manufacturing technologies, the project provides business- and technology insights. Companies along the whole value chain of pressure vessels have been involved, resins, fibres, liners, production systems, vessel manufacturers, hydrogen system integrators and OEMs.

The first phase of the project involved an in-depth review of regulations, requirements and safety standards, together with examples of state-of-the-art hydrogen pressure vessels. Key aspects covered included manufacturing processes, supply chains and production technologies, as well as a comprehensive patent analysis. In addition, the study examined winding patterns, design strategies, material models and software tools used in the development of pressure vessels.

The second phase of the project involved extensive engineering studies. Warden Schijve, Design Leader at AZL, explained the procedure: "Our team of experts developed CAE models for 12 different layouts of a two-metre, 350-litre Type IV pressure vessel designed for 700 respectively 350 bar applications. These models incorporated different resin and fibre types, layup variations and boss designs to evaluate the impact on mechanics, weight, cost and carbon footprint. We also explored hybrid fibre combinations and dome reinforcement using patch technologies. Detailed process chain modelling provided further insight into cost structures and CO2 footprints.”

The results of the project also show initial future trends: Through the targeted use of advanced material combinations, adapted designs and manufacturing techniques, it is possible to significantly reduce the weight and cost of the vessels while maintaining the necessary safety standards. Compared to state-of-the-art vessels, hydrogen over tank weight efficiencies could be improved from the standard 6 to 7% up to more than 11%. These developments could strengthen the competitiveness of hydrogen technology in various mobility and energy sectors in the future.

“The knowledge gained from the project provides a solid foundation for the use of new technologies to meet the hydrogen economy's requirements for safe and cost-effective pressure vessels,” commented Celal Beysel, Chairman of the Board at FLOTEKS Plastik San. Tic. A.Ş. Floteks, a Tier 1 supplier of plastic components, has launched numerous R&D initiatives in the design and development of Type IV vessels in recent years. In 2023, the company joined the AZL Composite Pipes and Vessels Working Group and the 'Trends and Design Factors for Hydrogen Pressure Vessels' project. Beysel added: "We are pleased to announce that Floteks has established a new company called Pressura in 2024, which will focus on the production of type 4 pressure vessels for buses and trucks."

Companies and organisations seeking detailed insights or collaboration opportunities are encouraged to contact AZL. AZL Aachen GmbH serves as an innovation partner for hydrogen tank development, prototyping and testing, and is dedicated to advancing composite technologies.

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.

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.

BTMA member Dent Instrumentation – a specialist in contactless yarn sensors – has become an employee-owned business following the formation of a new Employee Ownership Trust (EOT).

The company, based in Colne, Lancashire, has been family owned since its founder Geoffrey Dent secured a patent for the very first contactless yarn sensor in the 1960s. It has been successfully run by his son Andrew and the family for many years.
“This deal ensures a smooth succession as well as the preservation of the company’s core family values and the Dent Instrumentation name,” said Managing Director Colin Hull. “The EOT structure will maintain the integrity of the business for years to come.”

The liability of Dent sensors makes them integral to the yarn spinning and winding processes and they have become a standard throughout the textile industry, recognised for their quality, performance and value. They are used by major manufacturers of textiles and textile machinery under either Dent or OEM machine builder brands.
