BleNaBis: Climate-neutrale carpet fibres - awarded by KlimaExpo.NRW

The surfaces of carpets are generally made of wool or synthetic fibres such as polyamide. The carbon footprints of these two materials are not as “fluffy” as the carpets are soft however: wool production is an energy-intensive process as a result of keeping animals. In collaboration with other European research institutes, the Institut für Textiltechnik (ITA) of RWTH Aachen University is currently develops a climate-neutral yarn based on renewable raw materials, which will not only match the quality of polyamide, but can also be produced in a more energy efficient way.

The fibres consist of linseed fibres and a sustainable eco-polyamide fibre. The linseed fibre comes from flax fibre which is extracted from the stems of flax plants that are no longer needed. The eco-polyamide fibre consists of 70 percent castor oil, which is obtained from the castor oil plant, a plant that does not compete with the food production sector. The combination of these two fibres will make the carpet durable and of high quality. The fibre blend is expected to cut the climate footprint of a carpet by 50 %.

Quality control using the office chair simulator

More than 50 per cent of all carpets are not woven but “tufted”, whereby textile loops are worked into a fabric backing, similar to the method used in tatting. The quality standards are high and the carpets produced have to be subjected to very stringent quality analysis. An office chair simulator carries out a stress test to check whether the carpet can withstand the level of wear to be expected in an office.

Hybrid carpet yarn Linseedflax and biobased Polyamide 6.10 (c) 2018 ITA

BleNaBis (Blends of Natural and Biosynthetic fibres for eco-efficient yarns and carpets) covers all stages of the value added chain: from harvesting right up to producing the carpet.

The flax fibre is cultivated and processed in the Czech Republic; the ITA mixes the linseed fibre with the polyamide fibre and spins the yarn from this using the rotor spinning process. The production and testing of the carpets is then carried out at the TFI Institut für Bodensysteme an der RWTH Aachen e.V.

The BleNaBis project was funded by the Federation of Industrial Research Associations (AiF) as part of the programme to support Industrial Community Research and Development (IGF) through a grant by the German Federal Ministry for Economic Affairs and Energy, on the basis of a resolution passed by the German Bundestag.

The official award ceremony will take place at the beginning of 2018.

Engineer Dipl.-Ing. Marko Wischnowski and M.Sc. Tobias Schlüter, both ITA, Project Leaders of BleNaBis say: “In the BleNaBis project, we are developing processes used to produce flooring systems from bio-based polyamides and linseed flax fibres. The combination of these two materials allows us to improve the carbon footprint of flooring systems. In addition, we are demonstrating new areas of application for natural fibres and bio-based polyamides.”

Aachen Summer School: Textiles become smart through 3D printing and origami

From 21 to 29 September 2026, the Aachen Summer School will transform Institut für Textiltechnik (ITA) of RWTH Aachen University into a laboratory of the future: over the course of a week, students will use origami folding techniques and 3D printing to develop active textile structures capable of performing programmable movements. This interdisciplinary event combines theoretical foundations with practical prototyping – from digital modelling right through to functional textile prototypes.

ITA has developed a washable digital smart jacket with real-time feedback and an AI-powered app for rehabilitation

As part of the PhysioTaix research project, the Institut für Textiltechnik (ITA) of RWTH Aachen University is developing a digital smart jacket with integrated sensors. The jacket is washable and reusable; it tracks movements during rehabilitation exercises in real time and transmits the data to an app.

Circulose resumes recycling of discarded cotton textiles and appoints interim CEO

Circulose today announced its restart of commercial-scale production plant at Ortviken in Sundsvall, Sweden, marking a significant step in scaling next-generation materials for the global fashion industry. The Ortviken plant is the world’s first commercial-scale chemical textile recycling facility. Its restart demonstrates that the fashion industry is seeking ways to scale proven solutions that move beyond pilots and into commercial production.

Itema brings textile versatility to ITMA ASIA + CITME 2026

Itema announces its participation in ITMA ASIA + CITME 2026, taking place November 20–24 at the National Exhibition and Convention Center in Shanghai. In Hall 3 – Stand D06, the company will showcase two Galileo-RX rapier weaving machines weaving heavy denim and conveyor belt fabrics, demonstrating its ability to address different textile requirements with application-specific configurations. Five additional Itema machines at partner booths will extend the exhibition lineup to upper shoe fabric, label, Jacquard leno fabrics, and shirting, offering visitors a broader view of Itema rapier and air-jet weaving technologies.

Brückner showcases sustainable technologies for the future of textile finishing at ITMA ASIA 2026

With rising energy costs, increasing environmental requirements, and growing competitive pressure, textile manufacturers worldwide are facing the challenge of making their production processes both more sustainable and more cost-effective. As one of the world's leading specialists in textile finishing machinery, Brückner will present innovative solutions and advanced production technologies at ITMA ASIA 2026 in Shanghai. These technologies can play a key role in significantly reducing both energy consumption and emissions.
