Today, microplastics are found in soil, air, and all water sources, including rivers, groundwater, treated drinking water, with the majority originating from wastewater produced during washing process. The aim of this study is to determine how standard washing, drying, wearing simulated by mechanical abrasion 100% polyester multifilament fleece knitted fabrics contribute release formation fibrous fragments determining changes their total weight, thickness, dimensions, relative surface area. In addition, a new textile evaluation methodology was developed assess cover area (cover ratio) released microplastic fibers trapped on fabric surface. methods confirmed that amount increased continuously until third fifth cycle, after which nearly constant. Furthermore, large proportion shown have originated as residue manufacturing We recommend (i) machines should include 25 × 30 μm mesh filter reduce number down drain, (ii) flat textiles be prewashed factory, thereby effectively capturing more significant part first (iii) construction properties improved meet environmental requirements, (iv) newly method for analyzing loose surfaces can widely used quality control.
