Cetex goes Abu Dhabi

At the end of May 2025, the time had come - a coating system to produce spread and impregnated fibre tapes was installed and put into operation by Cetex Institut gGmbH in Abu Dhabi, 4600 km away from Chemnitz. The system allows the parallel production of up to 10 spread and impregnated fibre tapes.

The spreading of fibre rovings uses the principles of rope friction: as a result, the individual filaments spread out and the original roving width increases significantly, depending on the type of fibre. The focus of the installed machine is the processing of 12K carbon fibre rovings, which can be spread from 10 mm to more than 17 mm tape width with the technology used. The spread rovings are then impregnated with a thermoplastic dispersion. The drying module is designed for up to 450°C, so that PEEK dispersions can also be processed. The system speed is up to 10 m/min. The end product achieves a fibre volume ratio of up to 60% and a tape width of up to one inch in the doubled state, wound up as a disc spool.

The successful start-up marked the end of an exciting project, whereby the installation is only the beginning of a long co-operation.

Organisations interested in comparable coating systems have the opportunity to collaborate with the Cetex Institut gGmbH and carry out material testing on a modular prototype line available at the institute’s technical centre in Chemnitz.

Pellet press enables thermomechanical textile recycling on a pilot scale at ITA

Since the end of 2025, the technical centre of the Institut für Textiltechnik (ITA) of RWTH Aachen University has been equipped with a pellet press from the manufacturer Amandus Kahl GmbH & Co. KG, Reinbek, Germany. This press can efficiently compact shredded synthetic textiles at a throughput of up to 25 kg/h and process them into pellets with a diameter of 4 mm.

Fabolose: Fabricating vegan and circular leather alternatives from bio-tech-derived cellulose

Fabulose is an EU funded project coordinated by the German Institutes of Textile and Fiber Research (DITF). Its consortium consists of leading research institutes, biotech innovators, and industry stakeholders who aim to create high-performance, biobased and recyclable leather-like fabrics, using efficient biotech production routes for bacterial cellulose, cyanophycin and bacterial pigments

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.

JEC World 2026 returns with an unprecedented content program

Recognized worldwide as the leading trade exhibition for composite materials and their applications, JEC World returns on March 10-12, 2026, at Paris Nord Villepinte as the most ambitious edition to date, in line with its motto “Pushing the limits”. As the must-attend event for the composites industry, JEC World will offer an unprecedented program, blending conferences, markets insights, technical sessions, awards, and above all, a unique experience and invaluable connections.

Beyond the wardrobe – innovative cotton takes the spotlight

Cotton can do more – a lot more. Cutting-edge textiles and high-tech products made from 100% cotton prove just how powerfully performance and sustainability can come together. That very surge of innovation is front and centre at the 38th Bremen Cotton Conference, taking place March 25–27, 2026, at Bremen’s Parliament on the historic market square – culminating in a bold and dedicated closing session on Friday. In the spotlight: performance upgrades for pure cotton, smart strategies for circular textile waste solutions, and pioneering concepts for demanding technical applications. From natural fibre–reinforced composites to highly effective flame-retardant solutions, cotton steps out of the closet and shows the future potential woven into every fibre.

Keeping print inclusive: Empowering women in the print industry

Across all industries, cultivating a diverse and inclusive workplace is increasingly recognised as valuable and essential to long-term success. However, despite the print industry’s significant advancements in technology and innovation, visible representation of women remains limited. As the sector grapples with low recruitment, it’s important to challenge outdated perceptions. Creating real change, however, requires collective effort - no single company can do it alone.
