Hohenstein tackles infrared radiation in textiles
12/02/2013
It claims that many high-tech fabrics can block infrared (IR) radiation in the short and medium wave range, but the long wave spectrum can penetrate the body.
“We want to develop a finish that modifies the radiation characteristics of textiles in such a way that the long wave IR radiation reaching the textile will either be absorbed or reflected,” said project manager Stefan Gierling. “The main focus is on the reflective properties at warmer temperatures and the absorbent properties at colder temperatures.”
Researchers will apply an absorbent layer to the lining fabric and a reflective layer to the outer fabric. They say it should feature good comfort properties and be “adopted with little effort and reasonable costs”.
“The smaller the particle size of the materials used, the higher the percentage of long wave infrared absorption in comparison to the bulk material,” added Mr Gierling. “A combination of different materials and particle sizes is intended to achieve the desired effect.”
The results of the project will be available from autumn 2014.
