New DIN SPEC supports the development of textiles with low microfibre discharge

Building on a rapid test for the detection of microfibres in sample water presented in 2023, the sporting goods manufacturer Under Armour, together with the testing service provider Hohenstein and the measuring device provider PPT Group, has now published a standardised test method that enables the determination of microfibre release from textiles under simulated washing conditions. With the help of the new DIN SPEC 19292, apparel/textile companies along the value chain are now able to measure and (e.g. comparatively) evaluate the extent of fibre release of different materials as part of their product development.

The new DIN SPEC 19292:2024-12, developed by Under Armour, Hohenstein and the PPT Group, makes it possible to determine the (micro)fibre discharge of textiles during washing using a standardised test method.

Test method is suitable for materials made of man-made and natural fibres

During the manufacture and use, but also during the care of textile products made from synthetic materials, fibres are released into the environment and pollute the oceans as microplastics, for example. Depending on the washing programme selected, i.e. the temperature and mechanical load, different quantities of textile fibres end up in the wastewater, even when washing items made from natural fibres. This is where the DIN SPEC 19292 test procedure comes in: After a simulated washing process of a fabric sample using tabletop equipment and a defined amount of water, the sample water is filtered and, based on a visual evaluation with a microscope, the degree of fibre fragmentation by the textile material is determined.

“With our broad expertise in sustainable solutions, we have been supporting companies in the textile industry for years in better understanding the fibre discharge of their products into the environment, making it objectively measurable and reducing it in a targeted manner,” says CEO Dr Timo Hammer, summarising Hohenstein's contribution to the new DIN SPEC.

On the industry side, Under Armour was looking to develop an easy-to-use, accessible solution for its producers that would allow the company and others to avoid microplastics through product development. “In the apparel industry, assessing the fibre abrasion of garments can be a costly and time-consuming process,” explains Kyle Blakley, Senior Vice President of Innovation, Development and Testing at Under Armour. “With Hohenstein's expertise, our team was able to align our innovative new test method to the globally recognised framework of DIN SPEC 19292. This exciting milestone supports our aim to make the test method as accurate and internationally accessible as possible.”

In addition to working on the new DIN SPEC 19292, Hohenstein also offers further tests to determine the extent to which (micro)fibres degrade in the wastewater of production plants or in household laundry and how harmful the fibre residues are to the environment. The tests are carried out according to Hohenstein’s in-house methods as well as international standards and procedures.

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.

STFI showcases new Textile LAB Professional with focus on climate protection and sustainable technologies

The Sächsisches Textilforschungsinstitut e. V. (STFI) in Chemnitz is organising a themed day on 3 December 2026, focusing on climate protection and the environment. As well as showcasing current applications for green cities and natural fibres for lightweight construction, the event will feature machine demonstrations in the new Textile LAB Professional. Under the motto ‘Design meets Technology’, this networking event will also provide an insight into artistic student projects, thereby facilitating a professional exchange on creative perspectives and modern technologies for climate protection and the environment.

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.

25 years of medical devices: ITVP combines experience with innovation

ITV Denkendorf Produktservice GmbH (ITVP) is celebrating its 25th anniversary. On October 1, 2001, ITVP was founded as a subsidiary of the German Institutes of Textile and Fiber Research Denkendorf (DITF), Europe’s largest textile research center. This spin-off company made it possible to consolidate expertise in medical technology and significantly expand production, which had previously been initiated mostly in the DITF’s cleanrooms.

Mahlo introduces AI-supported Orthopac RVMC-20 plus at ITMA Asia 2026

From November 20 to 24, 2026, Mahlo GmbH + Co. KG will present its system portfolio for the textile industry at ITMA Asia in Shanghai. Together with its local sales and service partner Kuantex and Mahlo China, the Bavarian technology specialist will demonstrate at Booth C22 in Hall 7.1 how intelligent measurement and control technology can improve the quality and efficiency of textile production processes. The spotlight will be on the new Orthopac RVMC-20 plus, which combines precise weft straightening with fully integrated process control.
