Researchers at the Hohenstein Institute in Bönnigheim, in cooperation with their project partner Eschler Texti, are working hard on finding a way of being able to give an objective evaluation of the specific degree of transparency or opacity of textiles and also control it.
In this "hands-on" research using volunteers with different skin types, existing measuring methods already used in paper-making are to be transferred to real-life conditions in the textile industry. Participants in the optical trials assessed the transparency of a piece of white test fabric by means of a questionnaire. The findings from the tests will then be confirmed using actual skin types and finally converted into an objective method for classifying transparency.
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/set, even as textile materials are being constructed. In a further stage of the project, researchers will also investigate the effect of external influences such as wetness on the transparency of textile materials.
However, project leader Julia Gündel is reassuring: "Where they are still desirable, for functional reasons or in order to be fashionable, transparent textile materials will still be available." And surely it won't only be the organisers and participants in wet T-shirt competitions who will be pleased about that!
We are grateful to the Research Association the Textile Research Council for its financial support for ZIM project no. KF2136705HG9, which was provided via the Federation of Industrial Research Associations AIF as part of the Central Innovation Programme SME, with funds from the Federal Ministry of Economics and Technology (BMWi) following an Order by the German Federal Parliament.

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
