Does washing synthetic clothes release microplastic fibers?
Yes. A 2026 textile study confirmed that laundering polyester fabrics releases microplastic fibers, and it tested coatings that reduced fiber release in lab washing.
What it is
Polyester, nylon, acrylic, and spandex are plastic fibers. When they are washed, rubbing and tumbling can break off tiny fibers that leave with the wash water.
Babies and toddlers go through many clothes, blankets, and sheets. Choosing more natural fibers for high-use baby textiles can lower how much synthetic fabric your laundry handles each week.
What the study found
A 2026 study in ACS Environmental Au tested polyester fabrics during lab-simulated laundering. The researchers measured microplastic fiber release from coated and uncoated polyester textiles.
The study confirmed that laundering synthetic textiles releases microplastic fibers. It also found that a PDMS-based low-friction finish reduced fiber release by 27% to 37% overall in the tested mixed-fabric washing setups.
This does not mean coated polyester is the best answer for every home. It means friction matters. Less rubbing, gentler washing, and fewer synthetic loads can reduce shedding.
What to do
Wash synthetic clothes less often when they are not dirty. Use cold water, full loads, and gentle cycles. Skip high-friction washing when possible.
For baby basics used every day, choose materials such as organic cotton or bamboo when they fit your budget and needs. Wash new textiles before use.
