Extreme weather events (e.g. heavy rainfall), have significantly increased in recent years due to climate change. The release of climate-wrecking gases, such as CO2, also by the textile industry, plays a crucial role here. Flood damage to residential and commercial buildings often causes substantial costs. To mitigate these expenses, a watertight roller shutter system has been developed that automatically closes in response to rising water levels through sensor technology. For this purpose, aluminum slats have been combined with a mechanical stable ripstop woven fabric with a selected coating with watertight properties. The application and fixation of such functional coatings takes place on knife coating devices followed by stenter frames, which are operated worldwide with natural gas according to the current state of the art. One way to reduce CO2 emissions is to use hydrogen technology in the textile industry, e.g. through the implementation of special dryers. The talk will compare conventional methods with environmentally friendly equipment. This project was funded by the BMWK (ZIM funding no. KK5163011GM2 and FKZ 03EN2087B).
