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.

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.

Testing and research laboratory ensures safe and more sustainable products worldwide

For 80 years, Hohenstein has stood for independent testing, scientific expertise and practical solutions. Today, the testing and research service provider supports manufacturers and brands worldwide in making textiles, hardlines and medical devices safe, more sustainable and market-ready – thereby building trust among consumers. With an international presence and interdisciplinary expertise, Hohenstein supports its customers from production through to market launch, helping them navigate an environment of growing regulatory and societal demands.

A smarter way to verified Chemical Compliance

Hohenstein and GoBlu Drive Innovation in Sustainable Supply Chain Management As regulatory demands, customer expectations, and sustainability goals continue to grow, the ability to manage chemical compliance and data across complex supply chains has become critical. Hohenstein and The BHive® by GoBlu are initiating a strategic partnership to enhance chemical management in the textile sector. The collaboration delivers more than just a service – it provides an integrated, future-ready solution for brands, manufacturers and suppliers seeking trusted chemical management and credible sustainability.

Stylish design made from sustainable materials – two DITF research projects receive Techtextil Innovation Awards

Materials made from domestic, renewable raw materials reduce CO₂ emissions, prevent microplastics from entering the environment, and close the material cycle. The German Institutes for Textile and Fiber Research Denkendorf (DITF) are developing nature-based alternatives to synthetically produced and predominantly petroleum-based materials. Two research projects have received a prestigious Techtextil Innovation Award. NUO Flexholz and the lignin-coated material FormLig demonstrate that sustainable concepts can meet high standards of functionality and design. Both projects were carried out in close collaboration with industry.

ITM presents cutting-edge textile research at Techtextil

From April 21 to 24, 2026, the Chair of Textile Machinery and High Performance Material Technology (ITM) at TUD Dresden University of Technology will be presenting its current research at Techtextil, the leading international trade fair for technical textiles and nonwovens. In Hall 12.0, Stand D41, the team will be demonstrating how it combines high-performance fibers, AI-supported digital development tools and innovative machine technologies to develop textile solutions for lightweight construction, construction, medical technology and sustainable production from atom to product.

Fraunhofer IAP paves the way for "Green" carbon fibers

A new pilot plant in Guben is set to enable the production of bio-based carbon fibers. The plant is part of the Carbon Lab Factory Lausitz and will make an important contribution to the transformation of the Lausitz region—from a traditionally raw material- and basic industry-oriented region to a hub for innovative high-performance materials. The German federal government and the state of Brandenburg are providing the Fraunhofer Institute for Applied Polymer Research IAP with 53.3 million euros for this purpose.

Techtextil 2026 recognition for the UK’s FET

Fibre Extrusion Technology (FET) will receive the Techtextil 2026 New Production Technology Innovation Award at next week’s Techtextil in Frankfurt (April 21-24). The Leeds-based member of the British Textile Machinery Association (BTMA) has developed the FET-500, a new toxic solvent-free gel small scale system for the production of ultra-high-molecular-weight polyethylene (UHMWPE).
