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.

Manufacturers, brand owners, retailers and certification bodies all benefit from analytical evidence – all the way to the end product. Consumers can rest assured that no GM cotton has been detected in the articles they buy. © Hohenstein<br />

GMO-free textiles – an issue that is causing more and more consumers to turn to organic cotton. They are also happy to pay higher prices for it. © Hohenstein

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.

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.

Textile climate control system in workwear – exhibition at the 2026 SME Innovation Day!

Conventional protective workwear often reaches its limits during strenuous physical activity. In particular, the transport of sweat and excess body heat poses a problem. The German Institutes of Textile and Fiber Research (DITF) conducted research on flow-optimized, air-conducting textile structures that enable targeted climate control directly on the body. These structures can be integrated straight into protective work garments. The textile climate control system supports the body’s natural thermoregulation. This contributes to improved workplace safety and comfort.

Elastic yarns to become more recyclable and environmentally friendly in future

On 29 April 2026, ITA student Tobias Dickmeiß was awarded a sponsorship prize by the Wilhelm Lorch-Stiftung for his innovative approach, to replacing conventional elastane with elastic yarns made from thermoplastic copolyester elastomers (TPC). Thanks to their thermoplastic nature and compatibility with typical polyesters used in the textile industry, elastic TPC yarns offer improved recyclability. Furthermore, the use of the melt-spinning process in yarn production eliminates the need for solvents that are harmful to the environment and human health.
