TexDicht – Innovative textile ventilation through new sealing concepts
In the TexDicht research project, innovative textile ventilation seals are being developed and investigated. The concept of a textile seal is to be investigated in comparison to conventional silicone and rubber seals. In addition, innovative ventilation systems with the textile seals are to be worked out and tested. In particular, the combination of the sealing function and ventilation, e.g. "Schlöffnen", are of interest to the project. The textile seal must meet the requirements of an airtight window seal, i.e. it must withstand weathering, be UV-resistant and impermeable to water. In addition, it should ensure a better indoor climate through air permeability. The innovation is expected to eliminate the need for ventilation equipment (such as window rebate ventilators or ventilation systems), thereby reducing investment, operating costs and CO2 emissions. Specific properties of mesh technology (including air permeability, stretchability, compressibility, recovery, 3D knitting and form knitting) and textile finishing (by means of coatings that shield the surface from water or UV rays) will be specifically used and, if necessary, combined.
The textile structures are developed and tested for their textile properties at the Research Institute for Textiles and Clothing at Niederrhein University of Applied Sciences (FTB). At the Institute of Energy Efficiency and Sustainable Building at RWTH Aachen University (E3D), the samples will be tested in terms of building physics and their influence on the indoor climate. The project is accompanied by an interdisciplinary committee consisting of various companies, which increases the innovative capacity of the project and cross-industry synergy effects between the companies.
