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.”

TCLF: Resilient value chains in times of crises

The textiles, clothing, leather and footwear (TCLF) industry was at the centre of the webinar “Resilient value chains in times of crises”, which took place on 28 April 2026. Global supply chains continue to face increasing pressure, raw material dependencies are growing and economic uncertainties are affecting the entire sector.

Elastic yarns to become more recyclable and environmentally friendly in future

On 29 April 2026, ITA student Tobias Dickmeiß was awarded a sponsorship prize by the Wilhelm Lorch-Stiftung for his innovative approach, to replacing conventional elastane with elastic yarns made from thermoplastic copolyester elastomers (TPC). Thanks to their thermoplastic nature and compatibility with typical polyesters used in the textile industry, elastic TPC yarns offer improved recyclability. Furthermore, the use of the melt-spinning process in yarn production eliminates the need for solvents that are harmful to the environment and human health.

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.

Barmag and Hitech Automation enter into partnership for an auto-doff system for texturing machines

Barmag (Suzhou) Technology Co., Ltd. and Hitech Automation Solutions PVT LTD. of Surat, India, have agreed to an exclusive partnership to jointly market Hitech’s Doffmatic automation solution for Barmag’s proven manual eFK texturing machines. In many texturing facilities, manual doffing processes remain heavily operator-dependent – resulting in issues such as increased scrap, inconsistent quality, and limited productivity.

Uster’s new Recycling Opening Index guides spinners to the perfect blend

Uster AFIS 6 now offers the key data for better decisions when blending recycled fibers. Process control is decisive in determining the quality and economic outcome. The new R Recycling Module of AFIS 6 introduces the Recycling Opening Index (ROI), so spinners can optimize their circularity credentials. It was officially launched at ITM 2026 in Istanbul, Türkiye.

The heart of the technical textiles and nonwovens world will beat in Istanbul

Only 1 day remains until HIGHTEX 2026 International Technical Textiles and Nonwovens Exhibition opens its doors. Bringing together manufacturers, technology developers, investors, and industry professionals from around the world, HIGHTEX 2026 is preparing to showcase the innovations shaping the future of the industry. As the countdown to this major event continues, Istanbul is once again getting ready to become the meeting point of the global technical textiles industry.

Grasim Industries announces fresh investment of ₹3094 Crore to expand Lyocell capacity

Grasim Industries Limited, the flagship company of the Aditya Birla Group and a global leader in cellulosic fibres, today announced an investment of ₹3,094 crore, for Phase II Lyocell capacity of 110K TPA at Harihar, Karnataka. This expansion will consist of 2 lines of 55K TPA (150 Tons per day) each. The first line is expected to be commissioned by 2028, and the second line is expected to be commissioned by 2030.
