Antimicrobial textiles to help in reducing odour of perspiration

The team led by Dr. Dirk Höfer from the Institute for Hygiene and Biotechnology at the International Textile Research Centre of the Hohenstein Institutes in Bönnigheim has developed a two-stage test. This can be used to assess for the first time the effectiveness of antimicrobial textiles in reducing the odour of perspiration both qualitatively and quantitatively.
In the first stage, a microbiological cell model is used in which the antimicrobial textiles slow down the metabolism of micro-organisms that produce a specific odour substance. By using GC/MS analysis (gas chromatography-mass spectrometry), the formation of this odour substance can be quantified and hence the effectiveness of the antimicrobial materials assessed.
In a second test, trial users apply real perspiration from their bodies to the textiles in a controlled wear test. Specially trained testers then assess, qualitatively and quantitatively, the odour reduction in antimicrobial textiles compared with conventional textiles.
In future, manufacturers will be able to use the Hohenstein quality label directly on their products as evidence of the results of independent testing, and thereby provide independent confirmation of their marketing claims about the effectiveness of their functional textiles.
Now for the first time, with the help of a new test method, the extent to which antimicrobial textiles reduce the odour of perspiration can be assessed, qualitatively and quantitatively. Qualitative and quantitative testing for odour substances on materials and textiles is carried out using gas chromatography-mass spectrometry.
