Hohenstein advances textile sustainability with microfiber analysis.

Hohenstein has completed the development of its new method for analysing microfibreshedding from textiles. Using dynamic image analysis, the method quantifies shedding behavior and reveals previously unattainable data with practical implications for material development throughout the supply chain.

The new method is the result of four years of research at Hohenstein, published in anarticleby lead scientistJasmin Haap. The research team developed, refined and validated an analytical method that goes beyond current approaches of measuring the shedded mass to quantify fibre count, length, diameter and shape.

Further analysis can reveal the distribution of these attributes and even generate separate results for cellulosic fibres (e.g. cotton) and non-cellulosic fibres (e.g. polyester). This analysis is currently available exclusively through Hohenstein.

With this level of detail, researchers can now quantify in more detail which types of fibre and material constructions contribute most to microfibre release, leading to informed decisions in development of more sustainable textiles that shed less.Synthetic microfibres are tiny pieces of plastic released into water during mechanical stress, particularly washing. Wastewater containing microfibres eventually flows through sewage into larger bodies of water.

Along the way, synthetic microfibres attract harmful substances and pollutants from the environment, thus being able to reach sea life and entering the food chains of larger sea life and even humans. Dynamic image analysis of wastewater is non-destructive, allowing additional tests, such as filtration, to be performed for further analysis.

Filtration, the most common method to date, involves filtering the wastewater from textile laundering, then weighing the remaining particles.In November 2019, Hohenstein joined the Microfibre Consortium (TMC)as a contributing research member.

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.

POLYMERS-5B develops high-performance bio-based polyesters from agricultural waste

The European research project POLYMERS-5B is developing an integrated enzymatic biorefinery to convert agricultural by-products from Mediterranean food production into valuable raw materials for the food, cosmetics and bio-based plastics industries. Using tomato and olive pomace as feedstock, the process aims to recover several product groups from the same biomass stream. The consortium will present its latest technical developments and market findings at Ecomondo 2026 in Rimini on 3 November.

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.

Lenzing improves profitability as strategic transformation gains momentum

The Lenzing Group reported improved operating profitability in the first nine months of 2026 despite declining revenue and a challenging market environment. Revenue decreased by 2.3 percent to EUR 1.93 billion, while adjusted EBITDA remained stable at EUR 353 million. The adjusted EBITDA margin increased from 17.9 percent to 18.3 percent, reflecting progress in the company's strategic transformation under its “Grow Nonwovens. Reset Textiles.” strategy.

Texworld Apparel Sourcing Paris marks 30th anniversary with a redesigned exhibition concept

Texworld Apparel Sourcing Paris will celebrate its 30th anniversary from 25 to 27 January 2027 at the Paris-Le-Bourget Exhibition Centre. With more than 1,000 international exhibitors expected, the anniversary edition will introduce a redesigned exhibition layout across Halls 3 and 4, bringing fabric manufacturers and garment producers closer together. The event will also highlight Spring-Summer 2028 trends, sustainable sourcing and new opportunities for international textile trade.
