Hohenstein and Eschler look at transparent textile problem

17/09/2010
Researchers at Germany’s Hohenstein Institute are working with Eschler Textil to combat the problem of unintentionally transparent clothing, including sportswear.
The two organisations are looking at ways of giving an objective evaluation of the specific degree of transparency or opacity of textiles and also control it. The study uses volunteers with different skin types and is adapting existing measuring methods already used in papermaking.
As well as evaluating degrees of opacity, the project will also come up with guidelines for controlling transparency by the thickness and composition of the yarn. This will mean that, in future, the required degree of opacity will be able to be defined and applied, even as textile materials are being constructed. In a further stage of the project, researchers will investigate the effect of external influences such as wetness on the transparency of textile materials.
However, project leader Julia Gündel said: "Where they are still desirable, for functional reasons or in order to be fashionable, transparent textile materials will still be available."
