New test kit for textile microfibre shedding

In cooperation with testing provider Hohenstein, Under Armour is launching a new fiber-shed test kit. It will help textile companies along the supply chain to develop lower shed materials during product development. The companies carry out the test themselves in-house using the test kit or can commission Hohenstein as a testing service provider.

The kit is a one-off purchase, after which users can buy additional materials from project partner James Heal. By using the new kit, Under Armour can reliably assess the quality and shed rate of the materials from suppliers.

For Hohenstein customers, the test kit is a useful addition to their microplastics tests. It is a quick and relatively inexpensive preliminary test that ensures better early-stage results for the end product.

During the production, wear and laundering of synthetic and natural fabrics, fibre shedding occurs in varying degrees. Hohenstein and Under Armour expect that their test method will help the industry better understand and reduce its contribution to the microfibre problem.

“Until now, integrating fiber-shed testing into industry research and development activities has required a significant time and cost investment,” said Kyle Blakely, Senior Vice President of Innovation for Under Armour. “At Under Armour, we believe intervening early to mitigate shedding is critical, which is why our test method is designed to specifically address these time and cost barriers.”

Hohenstein: New quantitative method to detect genetic modifications in organic cotton

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.

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.
