Wood wool instead of crude oil: Scientists at TU Dresden develop sustainable biocomposites

In the "Lignowool_2" project, TUD researchers are developing a composite material made of wood wool and biodegradable, textile plastic fibers. The so-called lignowool composites represent a sustainable alternative to petroleum-based plastics. In future, they are to be used in the automotive industry for door panels and trunk floors, for example. This is a technical application of wood wool and promotes the use of natural materials.

Wood wool is used in everyday areas, for example as a cushioning filling and padding material in packaging, as an ignition aid, but also in horticulture and animal husbandry. It also has a load-bearing function in lightweight panels.

Due to its lack of malleability and low strength, conventional wood wool is currently not used beyond the areas mentioned. With the production of lignowool composites, the TUD scientists at the Chair of Wood Machinery and High Performance Materials Technology, together with the Institute of Textile Machinery and Fiber Materials Technology (ITM) and various practice partners, want to open up a new field of application for wood wool. In the first phase of the project, the technological feasibility of the composite materials was demonstrated. Now the knowledge gained is being implemented. Technical wood wool with previously unattained properties is created from solid wood by means of incisions made in a targeted manner and precise cutting. This is then combed with biopolymer fibers in a carding machine and thus structured. Further textile-technical process steps lead to pressable blanks, the so-called wood wool thermoplastic tapes. In the project, these are processed into prototypes for the above-mentioned automotive applications.

"The technical wood wool we process retains its typical wood properties. It is more stable than the previously established wood wool and has a high formability. It is also reproducible and can be processed using textile technology," explains project manager Sebastian Siwek. "By developing composites, we are closing a gap in the field of wood-based materials and increasing resource efficiency through a more holistic utilization of wood."

The project team is planning an industry-oriented pilot plant to test the process for broad application, further develop the wood wool manufacturing process and improve the combination of the various processing steps.

"Lignowool_2" will run for two and a half years and is funded by the Federal Ministry of Food and Agriculture. The project sponsor is the Agency for Renewable Resources (Fachagentur für Nachwachsende Rohstoffe e.V.).

ITM presents cutting-edge textile research at Techtextil

From April 21 to 24, 2026, the Chair of Textile Machinery and High Performance Material Technology (ITM) at TUD Dresden University of Technology will be presenting its current research at Techtextil, the leading international trade fair for technical textiles and nonwovens. In Hall 12.0, Stand D41, the team will be demonstrating how it combines high-performance fibers, AI-supported digital development tools and innovative machine technologies to develop textile solutions for lightweight construction, construction, medical technology and sustainable production from atom to product.

Teaching Award for the Day Of The Faculty of mechanical science and engineering 2025

On June 28, 2025, almost 300 guests celebrated the Day of the Faculty of Mechanical Science and Engineering at the Boulevardtheater Dresden. At this year's ceremony, over 60 graduates from the Mechanical Engineering, Process Engineering and Natural Materials Technology and Material Science degree programs were given a ceremonial send-off into professional life, 9 doctoral graduates were congratulated on the successful completion of their dissertations and prizes worth a total of 13,500 euros were awarded.

Commissioning of the FRS 1800 high-temperature rheometer at the ITM

In March 2025, the new Furnace System 1800 (FRS 1800) high-temperature rheometer from Anton Paar was put into operation at the Institute of Textile Machinery and High Performance Material Technology (ITM) at TU Dresden. The installation was carried out by Fabian Barth and Peter Brandes from Anton Paar in collaboration with Florian Pötzsch and Dr. Dilbar Aibibu from the ITM.

Walter Reiners Foundation Prize awarded to three ITA graduates

Sabina Dann, Lukas Balon and Annegret Storm from the Institut für Textiltechnik (ITA) of RWTH Aachen University were awarded the Walter Reiners Foundation Prize by the German Engineering Federation (VDMA) for their master’s and bachelor’s theses. Peter Dornier, Chairman of the Walter Reiners Foundation, presented the awards during Techtextil at the VDMA stand in Frankfurt am Main, Germany.

Young talents honoured – 60 years Walter Reiners Foundation

At the Techtextil trade fair in Frankfurt at the end of April, Peter D. Dornier, chairman of the VDMA’s Walter Reiners Foundation, presented awards to five successful young engineers. Promotion and sustainability awards were presented in the categories of bachelor’s/project theses and diploma/master’s theses. Academic theses are eligible for the sustainability awards if, for example, they develop solutions for resource-efficient products and technologies.

Regional hemp bast for lightweight construction profiles

The cultivation of fibre hemp for the production of ropes and clothing has a long tradition in Saxony. Due to its excellent fibre properties, it is also suitable as a renewable raw material for reinforcement in fibre composites. At the STFI and IWU in Chemnitz, the CannaPul project is cur- rently investigating how a regional value chain for hemp-based lightweight construction profiles can be established. To this end, the technical processing of hemp fibres into continuous fibre strands and their embedding in a suitable bio-based matrix are being investigated.

Barmag and Neumag showcase innovations across all manmade fiber processes

For the first time, Barmag is presenting itself alongside its new parent company, Rieter: At this year’s ITM in Istanbul, both companies will be represented from June 9 to 13 at the Tüyap Fair Convention and Congress Center in Hall 7, Booth 702B. As a technology leader in the field of chemical fiber equipment, Barmag will showcase its entire portfolio of systems for filament yarn, staple fiber, and nonwoven production, as well as solutions for the networked factory.
