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.

KARL MAYER opens a new TEXTILE INNOVATION CENTRE – a new era of textile innovation begins

KARL MAYER is opening its new TEXTILE INNOVATION CENTRE (TIC), sending a strong signal that it is driving textile innovation forward and opening up new perspectives for the textile industry. The TIC brings together the latest developments in Warp Knitting, Technical Textiles and Warp Preparation – KARL MAYER’s core areas of expertise.

Proven performance, optimised costs – the new RE 6 EL

Nowadays textile companies increasingly need to produce small production runs and respond to market changes with instantaneous pattern changes in order to operate profitably – meaning they require machines that offer maximum flexibility, reliability and cost efficiency. KARL MAYER understands the challenges of the market and is launching its new RE 6 EL. The Raschel machine offers the core strengths of the classic RSE 6 EL and essentially the same performance parameters, but has been further cost-optimised largely due to local production advantages. This makes the newcomer an efficiency champion in production, especially when it comes to frequent pattern changes.

New DIN SPEC assesses environmental impact of textile fragments in soil

Textile products made from synthetic fibres, finished fabrics or dyed materials release fibre fragments into the environment at every stage of their life cycle. With the new DIN SPEC 19296, Hohenstein has developed a standardised testing method to analyse how these fragments behave in soil under natural conditions. Until now, little was known about their environmental behaviour or potential ecological effects once released.

Award-winning research for sustainable carbon fibre cycles

Sustainable recycling of carbon fibres is possible through targeted electrochemical surface modification, which makes the sizing of carbon fibres resistant to solvolysis. ITA PhD student Sabina Dann was awarded the MSW Award from RWTH Aachen University for her master's thesis on this development. The award ceremony took place on 12 November 2025 in Aachen.

Sustainable, lightweight, and sound absorbing: Polyester-based front trunk solution for BEVs

As car manufacturers look to further reduce their carbon footprint, Autoneum has developed an innovative front trunk solution for battery electric vehicles (BEVs), made entirely from polyester-based textile. The Ultra-Silent Frunk offers significant weight reduction, improved acoustic and thermal insulation, and uses up to 70 percent recycled material, supporting sustainable and efficient vehicle design. Autoneum, global technology leader in acoustic and thermal management for vehicles, has already received orders for the new frunk from three major OEMs in Asia and Europe to be built in three BEV models. Series production for two BEVs has been underway in China and Germany since last year.

Modern testing methods for raw cotton

The 38th International Cotton Conference Bremen will take place from 25 to 27 March 2026 at the Bremen Parliament. This conference has traditionally stood for in-depth expertise and international exchange. The program will focus on technical innovations, market trends, and regulatory frameworks across the entire value chain – from agriculture to the circular economy. With high-profile speakers, the conference is regarded as the key meeting point for the global cotton industry. Today’s focus: Cotton quality and testing methods.

Rieter responds to higher raw material prices

Global political and economic developments have been leading to rising raw material and energy costs for some time. The textile machinery industry is also affected by this trend. Rieter machines and components consist to a large extent of steel, copper, aluminum and electronics. These materials in particular have seen higher demand and higher prices in recent months.
