Oil-water separation with bio-inspired textiles

Superhydrophobic biological surfaces are able to adsorb oil from water and separate it at the same time. In the BOA - Bionic Oil Adsorber project, this phenomenon was analysed in detail, abstracted and now successfully transferred to textile technology. Technical textiles are now available with which oils of different viscosities and compositions can be separated from water according to the biological role model.

The advantage of this method is that the oil is transported through the textile and can be collected with a floating container. Following this, it is possible to dispose of the oil properly. According to current findings, the textiles are reusable and suitable for permanent use.

The consortium consisting of the Nees Institute for Plant Biodiversity at the University of Bonn, the company Heimbach GmbH and the ITA Institut für Textiltechnik of RWTH Aachen University would like to thank the Deutsche Bundesstiftung Umwelt DBU for funding the project 34602/01-03 and all companies for the friendly support. If you are interested in the oil-adsorbing textiles, please contact Leonie Beek.

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.

Fraunhofer CCPE presents the “Monomaterial Design Set” – Innovative solutions for circular product design

Composite materials made from different types of plastic often extend the lifetime of products but make recycling more difficult in the circular economy. That is why Fraunhofer CCPE has developed the “Monomaterial Design Set”. This new approach helps to reduce the variety of plastics used in durable products and offers circular solutions for designers and product developers.

ROICA: Where distinction and intention shape the future of apparel industry at Milano Unica

At Milano Unica, held at Fiera Milano (Rho) in Milan from January 20–22, nine select European partners unveil collections shaped by ROICA™—the premium stretch fiber by Asahi Kasei. ROICA™ does not stand alone on the show floor, but its presence is quietly interlaced into each creation, chosen by those who seek distinction and depth in modern textiles. Through these dedicated collaborations, ROICA™ continues to sup-port the apparel industry with advanced stretch, comfort, and environmental care, offering something unique for brands who value true craftsmanship and thoughtful innovation.
