| Popis: | The pollution of marine ecosystems caused by plastic debris has become a major environmental problem in the last decades. In fact, such pollutants are quite concerning since they have a direct impact on marine flora and fauna but also on human health. From this point of view, particularly alarming plastic wastes are microplastics, fragments typically smaller than 5 mm in diameter, that remain unaltered in the marine environment and can be ingested by plankton or other marine organisms, eventually entering the human food chain. A new source of microplastics has been lately identified in the washing processes of synthetic clothes [1], composed of polymers like polyester, polyamide, polyacrylic and polypropylene. In such scenario, the aim of this work was to assess the role of domestic and industrial washing processes on microfibers release and consequently to find solutions to mitigate its environmental impact. For this purpose, standard polyester and polypropylene fabrics were washed with several methods, simulating both domestic and industrial washing conditions. The washing liquor was filtered and the filters were analysed by scanning electron microscopy (SEM), in order to identify micro and nanofibers detached from the synthetic textiles. Then, different textile finishing treatments were performed to prevent microplastics release from the fabrics. Among the materials used for the finishing, also biopolymers were taken into account and new treatments were experimented. Finally, the obtained results allowed to identify the washing conditions that are less aggressive on the fabrics and the treatments able to protect them, limiting the microplastics release. |
