It is widely known that the textile industry is a large polluter and that fast fashion in particular has sustainability issues. Meanwhile, second-hand stores struggle to sell their products in Europe, leading to most clothes either being exported and/or landfilled. This issue is partially driven by costumers not knowing what performance they can expect from second-hand products. In this study, the water repellency of used hardshell jackets will be evaluated with the goal of proving that second-hand products still have enough performance for reuse. This implies that prolonging the lifetime of waterproof jackets is possible, which will reduce CO2 emissions. Various standards are evaluated and a new method, dubbed the stream impact test is defined, trialed and compared to results from the ISO 4920 spray test. In order to estimate the full potential of reusing jackets, the effects of rejuvenating used jackets, by washing the mand using water repellent spray, are also tested. The current standards for aging fabric used by the industry to prove the durability of water repellency will be evaluated using both the ISO 4920 spray test and the new stream impact test. The testing concludes that while the new method has certain issues, it does achieve it’s core objectives and provides a new perspective on the water repellency of new, used and rejuvenated fabrics. It also shows that, on average, rejuvenating jackets has a good effect on the water repellency of jackets and that. During the testing of used jackets with the stream impact method, jackets are found with water repellent properties between those of new fabric and very old fabric. This suggests that there are jackets with a lot of technical performance left that are discarded, which would be ideal for reuse and allowing the clothing industry to become more sustainable.
