All Organic?

Hohenstein uses a new quantitative method to detect the type and extent of genetic modifications in organic cotton directly during the process chain.

There has been a sharp rise in demand for organic cotton products. Compared to conventionally grown cotton, the cultivation of organic cotton requires the renunciation of genetically modified seeds, chemical pesticides or fertilisers. Nevertheless, genetic modifications are repeatedly found in textiles that are falsely labelled with organic claims. Often, available certification systems are not backed up by lab testing. At best, they only take random seed samples. Textile testing specialist, Hohenstein, has developed an assessment method specifically for cotton. This new DNA analysis method makes it possible to ascertain the amount of genetically modified cotton contained in products. This is good news for textile industry stakeholders who will be on the safe side in terms of quality control and labelling of organic cotton products.

First step: qualitative screening and identification. Second step: quantification of genetically modified cotton.

For qualitative screening, Hohenstein experts had developed molecular biological detection systems to make clear yes/no statements about genetically modified cotton. Testing can be applied to all kinds of materials, from raw cotton to chemically untreated yarns and fabrics. In addition, Hohenstein is one of only a few laboratories in the world accredited to test for GMOs in accordance with the ISO/IWA 32:2019 protocol. Its method provides reliable evidence of the presence or exclusion of genetic modification in cotton textile precursors.

Once qualitative proof of genetic modification is obtained, Hohenstein experts begin quantifying the type and extent of the genetic modifications. To do this, they use DNA analysis to search for different cotton lines known to contain genetic alterations and quantify the proportion. Only by pinpointing individual genetic modifications and quantifying the extent of modification is it possible to provide precise information on whether there is an extremely small proportion of contamination, or whether larger proportions of GMOs have been mixed in. This offers clear benefits to manufacturers, brand owners and retailers when it comes to supply chain transparency and fraud prevention.

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.

Reducing development times for technical textiles by accelerated thermo-oxidative aging in a high-pressure autoclave

Synthetic polymers used in technical textiles can be effectively protected against degradation caused by heat, oxygen, and water through the use of stabilizer systems. This enables service lives of several decades, extending to more than 50 years. As the use of durable technical textiles continues to grow, so does the demand for reliable methods to predict their service life within economically feasible testing periods. For the first time the German Institutes of Textile and Fiber Research Denkendorf (DITF) developed methods for robust service life prediction for textiles in an IGF research project.

ITA has developed a washable digital smart jacket with real-time feedback and an AI-powered app for rehabilitation

As part of the PhysioTaix research project, the Institut für Textiltechnik (ITA) of RWTH Aachen University is developing a digital smart jacket with integrated sensors. The jacket is washable and reusable; it tracks movements during rehabilitation exercises in real time and transmits the data to an app.

ADD-ITC 2026 highlights strong industry participation

The Aachen-Dresden-Denkendorf International Textile Conference (ADD-ITC) 2026 will place a strong focus on the exchange between textile research and industry when it takes place on November 26–27, 2026, at the International Congress Center Dresden. According to the preliminary conference program, more than two-thirds of all presentations will be contributed by companies or jointly presented by industry and research institutions.

Coats Digital launches AI-powered GSD RealMotion for motion analysis

Coats Digital has launched GSD RealMotion, an AI-powered solution designed to provide apparel manufacturers with greater visibility into factory-floor operations. By analysing shop-floor video and applying Coats Digital’s GSD methodology, the solution turns video recordings into structured, motion-by-motion method studies.

Archroma and Lameirinho partner in pioneering deployment of InOneGO single-step dyeing

Archroma, a global leader in specialty chemicals, and Lameirinho, a leading home textiles manufacturer based in Portugal, are collaborating to bring InOneGO by Archroma, a new single-step dyeing process, into commercial production. Lameirinho’s first InOneGo bedlinens collection is now available worldwide.

25 years in the room: EDANA’s OUTLOOK™ returns to Cascais to shape a changing industry

The market does not wait, and it does not grant easy answers. Across the absorbent hygiene, personal care, and wipes sectors, business is undergoing a period of intense, necessary adjustment. New European rules on packaging, single-use items, product safety, and end-of-life are forcing companies to drop old assumptions about materials and performance. At the same time, producers must keep their goods safe, reliable, and affordable for the babies and aging adults, who rely on them every day.
