Textile microplastics: New standard assesses fibre release, biodegradation and ecotoxicity for the first time

Regarding environmental impact, the biodegradability of fibres in wastewater plays a decisive role. The biodegradability is determined after a defined period, by measuring fibre residues in the wastewater. © Hohenstein

Testing service provider Hohenstein has worked with the project partners Trigema, Freudenberg, DBL ITEX and Paradies to create a new standardized test method for detecting and classifying the environmental effects of textiles during washing. DIN SPEC 4872 combines analysis of fibre release, biodegradability and ecotoxicity. The test method according to DIN SPEC 4872 shows how many fibres are released during textile laundering, how well these fibres degrade in wastewater and how harmful the fibre residues are to the environment.

Studies have shown that washing textiles releases microfibres into the wash water, which cannot be sufficiently retained by wastewater treatment plants. Synthetic fibres pose the greatest risk to the environment because of their longevity and inability to biodegrade. However, Hohenstein project manager Juliane Alberts does not give the all-clear for biodegradable fibres and natural fibres: "Biodegradability alone does not mean that pure natural fibres, for example, are completely harmless to the environment. They, too, remain in ecosystems until they completely degrade and can also have a negative impact. In addition, additives, auxiliaries or finishes used in textile production can further slow the degradation process and leach into the environment."

The new standard enables textile producers and suppliers to test, evaluate and compare products for fibre release during washing and environmental impact. Juliane Alberts sees this systematic evaluation as an opportunity for the textile industry to take the initiative on environmental impact: "Our reliable data can be used as a basis for more targeted product development. This is a way to actively and consciously control further environmental pollution."

A new standard to combat plastic waste in forests

With DIN SPEC 35808 “Tree Shelter for Forestry Applications,” the testing and research service provider Hohenstein, in collaboration with Rottenburg University of Forestry, as well as forestry authorities and industry partners, has established a clear framework for bio-based and fully biodegradable tree shelters. The pre-standard defines requirements and practical testing methods designed to reduce plastic waste in forests and strengthen the long-term protection of soil and the environment.

Hohenstein publishes 2025 Sustainability Report

The testing and research service provider Hohenstein has published its latest sustainability report, outlining key progress and strategic initiatives. The report focuses on ambitious CO₂ reduction targets, the company’s new mission statement and the systematic expansion of sustainable services for customers worldwide.

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.

Outdoor Industry Association completes Clean Heat CoLab initiative

The Outdoor Industry Association (OIA) has completed its multi-year Clean Heat CoLab initiative, bringing together outdoor brands and technology experts to accelerate the adoption of electrified process heating in textile manufacturing. The collaboration focused on reducing emissions from thermal processes such as dyeing, washing and finishing, which remain among the most carbon-intensive stages of textile production.

Europe is committed to recycling end-of-life wind turbine blades

Starting in 2026, Europe’s wind energy industry has committed itself to ensuring that wind turbine blades do not end up in landfills once they reach the end of their service life. The EU-funded research project REWIND is exploring ways to reuse this composite waste. The German Institutes of Textile and Fiber Research Denkendorf (DITF) are one of 13 project partners from seven countries.

ADD-ITC 2026 publishes preliminary conference program

The organizers of the Aachen-Dresden-Denkendorf International Textile Conference (ADD-ITC) 2026 have released the preliminary program for this year's event, which will take place on November 26–27, 2026, at the International Congress Center Dresden. The conference is expected to attract between 500 and 700 participants from industry, research, and academia.

Première Vision Paris expands innovation focus across fashion and beauty

From September 1–3, 2026, Première Vision Paris will bring together more than 900 exhibitors from across the global fashion value chain. This year's edition places a strong emphasis on Innovation-Tech, highlighting technologies and materials that are reshaping product development, manufacturing and sustainability.
