Synthetic fabrics, such as polyester, nylon, and acrylic, are known to shed more microplastics when washed compared to natural fibers like cotton or wool. This shedding is primarily due to the nature of the synthetic materials, which are made from petroleum-based plastics. Here are some synthetic fabrics that are more likely to shed microplastics:
Fleece: Fleece fabric, often made from polyester, is a common culprit of shedding microplastics. The loose, fluffy texture of fleece tends to release more fibers during washing.
Activewear and sportswear: Many activewear garments, including workout leggings, athletic tops, and synthetic blends used in sports clothing, often contain polyester or nylon fibers. These fabrics are engineered for moisture-wicking and durability but can shed microplastics in the washing process.
Microfiber fabrics: Microfiber materials, often used in items like towels, cleaning cloths, and bedding, are typically made from synthetic fibers like polyester. These fine fibers can easily break off during washing, leading to microplastic shedding.
Stretchy and synthetic blends: Fabrics that contain a high percentage of synthetic fibers or a blend of different materials, such as spandex or elastane mixed with polyester, can shed microplastics.
It's important to note that even though synthetic fabrics tend to shed more microplastics, microplastics are a pervasive issue in many laundry processes. They can be released from various sources, including synthetic fibers, but also from other household items, like carpeting, upholstery, and even airborne particles. To help mitigate microplastic pollution, you can take steps such as using a washing machine filter or choosing clothing made from natural fibers when possible. Additionally, washing clothes on shorter, gentler cycles with cold water and reducing the frequency of washing can also help minimize microplastic shedding.
