Leading technology for high-level research

Textile reinforcements in concrete do not require any corrosion-related covering and thus make building cheaper, more environmentally friendly and more versatile. Completely new architectural solutions can be implemented through the slender construction forms of textile concrete. The Institute for Textile Technology (ITA) at the RWTH Aachen University is investigating what is actually possible. Already between 1999 and 2011, the Construction Composites Research Group developed textile reinforcement structures for concrete structures as part of the Collaborative Research Centre 532.

KARL MAYER’s new BIAXTRONIC® CO at the RWTH Aachen University for innovative semi-finished fibre products

The work was carried out on a KARL MAYER Malimo machine, and then continued at the ITA after 2011. Recent textile projects placed high demands on machine technology and required new investments. Once again, the ITA opted for a model from KARL MAYER. “The Malimo was already a great machine. Unfortunately, it was just getting on a bit,” says Martin Scheurer from the Department of Textile Machinery and ITA, when explaining their choice. He and his colleagues also valued KARL MAYER as a competent partner when it came to questions and service. They are now excited about the newcomer: a BIAXTRONIC® CO was delivered to Aachen at the end of 2020. It had been completely assembled and functionally tested in advance at KARL MAYER Technische Textilien in Chemnitz, since it is a tailor-made model. The high-performance warp knitting machine with course-oriented weft-insertion was equipped with novel functions that will open up new research paths for the ITA and its research partners.

A made-to-measure model

BIAXTRONIC® CO is predestined for the production of biaxial non-crimp fabrics and composite structures, and was equipped with specific features for its use at the ITA. One of these is KAMCOS® 2. The latest generation of KARL MAYER’s Command System offers an ethernet interface for integrating the machine into an existing network. This enables participation in future-oriented research topics such as Industry 4.0, inline quality control, sociology and process chain networking.

“We are planning to transmit the data from the producing machine via ethernet to the Internet of Production Excellence Cluster at RWTH Aachen University. The cluster deals with production research in high-wage countries,” explains Martin Scheurer. The BIAXTRONIC® CO for the research facility was also equipped with an EL pattern drive. Electronic guide bar control and the ability to vary process parameters inline contribute to the production of locally adapted, tailor-made textiles.

What’s more, the product quality can also be significantly improved. For example, Martin Scheurer wants to use the EL drive to investigate the influence of the warp knitting thread in different lapping variants on the geometry of the roving used and thus on the behaviour of the finished grid structure. Other details that favoured the BIAXTRONIC® CO are a working width that meets standard industrial practices and the possibility of feeding basic substrates such as nonwovens in a standard process.

Research- and practice-based projects

With BIAXTRONIC® CO, ITA researchers want to further develop and produce reinforcement structures for concrete matrices in particular. Functional models and prototypes for other areas of application are also to be produced on the machine. Martin Scheurer and his team want to produce reinforcements for wound dressings and hybrid warp knitted fabrics on a nonwoven substrate, for example. The combination of grid structures with other materials facilitates fundamental research into geotextile applications. Projects for filtration technology can also be implemented. The production of unidirectional (UD) non-crimp fabrics for fibre composites and of flat warp knitted fabrics for heating textiles, which can be used in the mobility sector, are also conceivable. In addition to research and development work, the ITA has its sights set on production practice using the BIAXTRONIC® CO. Users of weft-insertion machines can use the capacities and expertise in Aachen to optimise their production processes, produce prototypes of new textile structures or even test the processing of new materials.

Save the date: discovery awaits

Interested parties can find out what can be done with the BIAXTRONIC® CO on 19 April 2021. To kick off the new year, the ITA invites you to discover the new machine as part of a one-day industrial event. “We look forward to exchanging information with industry and research partners from all over the world,” says Martin Scheurer. He is looking forward to stimulating discussions on the needs and future developments relating to companies in the manufacturing sector in particular.

More Jacquard. More functionality. More fashion.

Available in gauges E 28 and E 32, this new model helps manufacturers set their collections apart from the competition. The fine E-32 gauges, in particular, impress with their clean surface, a pleasantly soft feel, and an exceptionally elegant look.

KARL MAYER's HKS 2-SE Expands Possibilities for Premium Stretch WARP KNITS

Warp knitted fabrics with a woven look are more in demand than ever in the fashion and apparel industries. Stretch WARP KNITS, in particular, impress with their freedom of movement, breathability, and virtually wrinkle-free wear – thereby opening up new style worlds such as smart casual or business casual. When it comes to the highly efficient production of premium-quality stretch WARP KNITS, the HKS 2-SE has long been the machine of choice. KARL MAYER’s best-selling tricot machine produces standard elastic fabrics characterized by high gauges, smooth, delicate surfaces, and a soft hand feel.

ALADIN paves the way for circular and demand-driven textile production in Europe

Textile production can be organized sustainably by utilizing short supply chains and preventing overproduction. This can already be achieved today by intelligently connecting and efficiently utilizing existing infrastructure. At the same time, production becomes circular when innovative technologies and materials are used that enable high-quality recycling. The ALADIN research project, launched in May 2026 and co-funded with five million euros under the EU Horizon Europe program, is creating the conditions for this.

TERIS reaches milestone: Fraunhofer consortium develops new standards for tire analysis

In the “TERIS” project, the Fraunhofer institutes ICT, IGD, and IWM—led by the Fraunhofer Institute for Structural Durability and System Reliability LBF—have reached a decisive milestone. For the first time, the teams aim to generate, analyse, and predict tire wear in the laboratory in a standardized and practical manner. As part of this milestone, results are now available on reference abrasion, particle analysis, tribological models, AI-based surface analysis, a test bench concept, and methods for accelerated aging and VOC detection. The tire industry, testing services, and environmental agencies will in future benefit from reliable, rapid laboratory procedures for emissions assessment.

Geotextiles made from recycled materials: GREEN leads the way into the industry
