Abstract

To get more information on the long term behaviour of technical textiles and on related degradation processes, the degradation of different synthetic fibres (polyester, PYC-coated polyester, polypropylene, polyethylene, polyamide 6 and 6.6, m-aramide) were investigated under the combined influence of pollution gases and light. Laboratory weathering experiments were performed in a specially designed climatic chamber, using different atmospheres such as normal air, zero air and zero air with pollution gases (NO2, SO2, O3, NO2/O3) added. Outdoor exposure tests are in progress at eight sites in Switzerland each having its specific meteorological conditions and typical environmental load. The exposure sites were chosen at locations of the Swiss National Air Pollution Monitoring Network (NABEL), where concentrations of air pollutants and climatic data are registered continuously. Results of tensile tests on laboratory and outdoor exposed samples are given. Comparison is made between laboratory ageing and outdoor exposure.
