The well being of the crew can be affected in space under microgravity conditions by the lack of convective and evaporative heat loss. This lack of heat loss can also have an impact on the health and safety of the crew. Microbiological or fungal contamination from clothing could impact the immune system by causing rashes from bacterial or fungal growth. Ground based studies have shown that there can be a rapid rise in core temperatures, in the absence of adequate hydration, due to a circumstances such as high humidity, heavy physical workloads, and fluid loss (sweating). This could result in stress related injuries such as heat strokes. These same events could occur for the crew when performing heavy physical exercise as well as during Extravehicular Activity (EVAs) under microgravity conditions.

To address these issues, Spacetex-2, in a joint endeavor between the Hohenstein Institute and DLR Space Administration, will investigate new Spacetex fabric. The new fabric has enhanced evaporative heat loss and sweat evaporation capabilities and will be worn during the crew’s regular daily sports activities on the ISS. Spacetex-2 is the follow-up project of Spacetex research and builds upon the first initial results and insights gained on the performance of the special fabric and it’s ability to deal with heat and moisture transport under micro-g conditions.

Specifically the research goals are:

  1. Increase the basic knowledge about the heat transfer/heat exchange from the human body to the environment under terrestrial and micro-g conditions; determine the evaporative heat loss in space during physical exercise
  2. Test the potential of new fabrics which might facilitate heat transfer/heat exchange from the human body in space and reduce microbiological/fungal contamination.
  3. Improvement of the overall comfort and well-being of the astronauts on board of the ISS
