ITA postdoc Dr Leonie Beek is revolutionising oil filtration with a bionic textile

On various biological surfaces, oil is adsorbed from water surfaces and transported along the leaf. In her dissertation, ITA Postdoc Dr Leonie Beek transferred this effect to a technical textile using her Bionic Oil Absorber (BOA), which can remove up to 4 litres of diesel per hour from water at technological readiness level 4. For this development, Dr Beek was awarded the Paul Schlack Prize 2025 for her dissertation ‘Bionic textiles for oil-water separation modelled on superhydrophobic biological surfaces’ on 10 September 2025. The award ceremony took place during the opening event of the Dornbirn GFC Global Fiber Congress in Austria.

Paul Schlack Prize 2025 goes to Leonie Beek

Dr Leonie Beek's dissertation focused on the sustainable separation of oil and water. On various biological surfaces, oil is adsorbed from water surfaces and transported along the leaf. This effect differs from technical solutions in that oil-water separation is achieved without external energy and without toxic substances.

Possible use in harbour basins or in the event of flooding/pollution of inland waters

Dr Beek integrated the bionic textile into a floating device (Bionic Oil Adsorber – BOA). The BOA demonstrator, which has a technology readiness level of 4, can remove up to 4 litres of diesel per hour. It is intended for use in port areas. Another promising application is in the event of flooding and pollution of inland waters and urban sewage treatment plants.

Ecologically and economically sustainable technology

The technology is ecologically sustainable, as both the textile and the separated oil can be reused. It is also economically sustainable, as the textile is up to 13 times cheaper than sorption materials with a service life of 21 days.

Overall, Dr Leonie Beek succeeded in her dissertation in transferring the biological principle to a bionic textile and presenting a product for use in the completely new application of oil-water separation. This is the first time that superhydrophobic surfaces have been used outside of friction reduction.

With the Paul Schlack Prize, CIRFS promotes innovation in man-made fiber research at universities and research institutes. The award ceremony took place during the opening event of the Dornbirn GFC Global Fiber Congress in Austria.

Background

Since 1971, the Paul Schlack Prize has been awarded at the Dornbirn GFC Global Fiber Congress (formerly Dornbirn Man-made Fibers Congress) in Dornbirn (Austria) to promote chemical fibre research at universities and research institutes. Previous ITA winners of the Paul Schlack Prize include Dr Stefan Peterek, Dr Andreas De Palmenaer, Prof. Dr Gunnar Seide, Dr Wilhelm Steinmann, Dr Stephan Walter, Dr Gisa Wortberg, Dr Benjamin Weise, and Dr Markus Beckers.

Exchange data between textile companies openly, securely and cost-effectively without a central platform – ITA makes it possible

The Institut für Textiltechnik (ITA) of RWTH Aachen University has launched a new demonstrator for an open and secure data space in the textile industry at the Digital Innovation Centre Europe (DICE). For the first time, the demonstrator shows directly and clearly how companies can share their data securely with each other without the need for a central platform. Data exchange is based on shared, freely usable technical foundations.

Sustainable athletic wear made from bio-based Polyethylene

Conventional sports textiles made from petroleum-based synthetic fibres are to be replaced in the future by sustainable, bio-based, cooling textiles. Polyethylene, previously used mainly in the packaging industry, is thus qualified for use in textiles and, as a bio-based drop-in solution, offers a cost-effective, sustainable alternative for the future.

Small tolerances, big impact and a recyclable alternative to elastane

ITA Master's student Janne Warnecke investigated tension differences over the fabric width in the weaving process and thereby contributed to quality assurance; ITA Bachelor's student Jasmin Roos found a basis for the development of recyclable yarns and textiles. For these developments, they were awarded the Walter Reiners Foundation's Promotion and Sustainability Prizes on 27 November. Peter D. Dornier, Chairman of the Walter Reiners Foundation, presented the awards at the Aachen-Dresden-Denkendorf International Textile Conference (ADD-ITC) in Aachen, Germany.

Innovation center for textile circular economy inaugurated

Just over eight months after the foundation stone was laid, the new Innovation Center for Textile Circular Economy was officially inaugurated today at TITK Rudolstadt. Thuringia's Minister President Mario Voigt, TITK Director Benjamin Redlingshöfer, and other guests of honor cut the ribbon to the modern building complex and viewed the premises, which are now ready for occupancy. The “DICE – Demonstration and Innovation Center for Textile Circular Economy” is TITK's largest single investment to date. The Free State of Thuringia supported the total cost of €11.5 million with €8 million in GRW and FTI funding.

Sustainable design of Geosynthetics and roof underlayments made from recyclates

Is it possible to recover plastic recyclates from previously unused waste streams in order to produce high-quality fibers and films? How can bio-based polymer fibers be manufactured so as to allow adjustable biodegradability? These are the questions being addressed by researchers from the Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE in the Zirk-Tex project.

More safety and comfort for protective clothing thanks to auxetic fabrics

When everyday materials are pulled, they stretch or elongate in the direction of the pull and become narrower in cross-section. We can also observe this property in two-dimensional textiles. Auxetic structures behave differently here. They have the striking property of not changing under tensile stress or even increasing their width or thickness. These properties are advantageous, for example, in protective textiles or textile filter media. The DITF are researching auxetic fabrics for various applications.

Cinte Techtextil China 2026: redefining business encounters for trending sub-sectors and cutting-edge technologies

The essence of a good trade fair is to create chance encounters to deliver tangible business value to its participants. Driven to stay ahead, Cinte Techtextil China is constantly seeking fresh strategies to keep the industry attuned to emerging trends, pinpointing high-potential segments for technical textiles and nonwovens. With a new zone and upgraded fringe events introduced, the last edition saw an impressive 17% increase in visiting numbers[1], and this year’s fair is set to leverage that success from 1 to 3 September at the Shanghai New International Expo Centre.

Epson launches SureColor G9000: high-production Direct-To-Film printer delivering greater productivity and reliability

Epson today announces the launch of the SureColor G9000, a new high-production Direct-To-Film (DTFilm) printer designed to meet growing global demand for flexible and efficient textile transfer printing. Expanding Epson’s DTFilm line-up alongside the SC-G6000, the SC-G9000 introduces enhanced speed, reliability and ease of maintenance for commercial garment decorators and textile producers.
