Ever since they were first noticed a couple of decades ago, microplastics have been looked for everywhere, and have been found wherever they have been looked for, including the tallest mountains, deepest trenches in the ocean, the air, soil, water, and in our bodies. The major sources are tire wear particles, paints, and synthetic textiles, which shed them, while being made, while being worn, when being washed and dried, and when they are discarded. One load of wash can release millions of microfibers. They are eaten by animals large and small and get into food chains. The microplastic fibers released by textiles are ubiquitous and often more problematic than other shapes such as spheres or fragments. Approaches to control or reduce their release include devices placed into washing machines to collect them, but a better, more upstream, approach would be to re-engineer textiles to release fewer microfibers. That's where textile scientists are needed.
