The new polyester staple fiber process EvoSteam from Oerlikon Neumag receives the bluesign® test label "bluesign® VERIFIED DATA". For this, the innovative, energy and resource-saving EvoSteam process had to undergo strict data verification. It impressed with savings in energy, water and raw material consumption, as well as a reduction in operating costs (OPEX) and the CO2 footprint.

All relevant process data was compared with the conventional drawing process and analysed. The results are impressive: "I am delighted that, following intensive development work on the new EvoS-team process, we have been able to reduce the total energy consumption for steam and electricity by up to 8%. In addition to reducing production waste by up to 50%, we expect to save around 3.2 million litres of water per year. For the operators of our plants, these are considerable cost savings while at the same time reducing impact on the environment by reducing the CO₂ footprint by around 6%," says Dr Friedrich Lennemann, Head of Technology Development at Oerlikon Neumag, summarising the result. By receiving the bluesign® VERIFIED DATA label, Oerlikon Neumag is not only emphasising its commitment to sustainability. All polyester staple fibers produced with the EvoSteam process will actively contribute to the bluesign® SYSTEM in the future.

bluesign® VERIFIED DATA

For the EvoSteam process, Oerlikon Neumag received the bluesign® VERIFIED DATA label for the first time. The label includes the verification of impact data such as water, spinning preparations, thermal and electrical energy as well as the CO₂ footprint by means of a plausibility check of the supporting records for the EvoSteam draw line, the central element in the EvoSteam process. The reported data was assessed as 2.1 - fair - in accordance with the defined methodology.

EvoSteam process for sustainable staple fiber production

The EvoSteam process was presented to the global public for the first time at ITMA 2023 in Milan. Visitors to the trade fair spoke of a major development step, as the EvoSteam process dispenses with liquid baths. The function of the immersion bath is assumed by a carefully-coordinated setup of godets and pulsed spray nozzles. With this, the moisture is metered precisely and added according to the needs of the process. This completely dispensing with liquid baths generates significant savings in terms of water, energy and finishes, while also increasing occupational safety and cleanliness at the production line.

Dutch court orders Shanghai Port Star to stop sales of HMPE link chains in EU

The District Court of The Hague has ordered Chinese supplier Shanghai Port Star to stop selling and distributing certain synthetic fiber link chains in the European Union after finding that the products infringe EU design rights held by Avient Corporation. The ruling concerns link chains made from high-modulus polyethylene (HMPE) fibers for marine and industrial applications.

ITMA Asia 2026: How Barmag is reshaping the future of man-made fiber production

The textile industry is entering a groundbreaking era. Manufacturers face rising energy prices, growing sustainability demands, increasing labor shortages, and an unprecedented need for flexibility. For a globally active textile industry, where competitiveness is closely linked to production efficiency and cost leadership, this means that technology is no longer merely a means of improving operational processes – it is increasingly becoming a strategic differentiator.

Greater efficiency for tomorrow’s textile industry

From September 24 to 27, 2026, Barmag, together with BB Engineering (BBE), will present innovative solutions for the efficient and sustainable production of synthetic yarns at the Egy Stitch & Tex Expo in Cairo, Egypt. Under the motto “A New Era. Powered by Innovation.,” experts from Barmag and BBE will present technologies spanning the entire textile value chain — from melt to yarn — at the ATAG Ltd. booth (Hall 1, Booth C1).

180 years of TESTEX: From Zurich silk testing to global certification

For 180 years, TESTEX has developed alongside the textile industry while maintaining the same underlying purpose: creating trust through independent and reliable measurement. Founded in Zurich in 1846 as the Zurich Silk Conditioning Institute, TESTEX has grown from a local institution serving the silk trade into an international Swiss testing and certification institute for textiles and leather.

Moving Advanced Recycling from Innovation to Implementation

The Advanced Recycling Conference 2026 explores technologies, markets, financing and scale-up of innovative recycling solutions for waste streams including mixed plastic waste, textiles and PVC. Europe’s chemical and materials sector faces growing pressure to close carbon loops, strengthen raw-material safety and resilience and meet increasingly ambitious EU recycling targets. Against this backdrop, the Advanced Recycling Conference (ARC) will bring together industry leaders, technology providers, researchers, innovators and policy-makers on 17–18 November 2026 in Cologne, Germany.

German textile industry and retailers form alliance to shape textile EPR system

Germany’s textile and fashion industry and retail sector have joined forces to establish the “Alliance for Textile Circularity” (Allianz für textile Kreisläufe). Initiated by the German Textile and Fashion Industry Association (Gesamtverband textil+mode) and the German Retail Federation (HDE), the alliance aims to contribute industry expertise to the development of Germany’s future Extended Producer Responsibility (EPR) system for textiles and footwear.
