Are recycled textile fibers a source of microplastic shedding?
Use caution with recycled polyester. Recycling can be better than disposal, but repeated mechanical recycling increased microplastic fiber release in a 2026 textile study.
What's actually in it
Recycled textile fibers are not all the same. Recycled cotton and wool are different from recycled polyester. The main microplastic concern is recycled synthetic fabric, especially recycled polyester.
Mechanical recycling can weaken fibers. Weaker fibers can shed more during wear, rubbing, and washing. That matters for baby blankets, pajamas, play mats, and other soft items that touch skin and collect dust.
What the research says
A 2026 Environmental Science & Technology study tested fabrics containing 30% mechanically recycled polyester. Once-recycled polyester shed about 1.4x as many microplastic fibers as virgin polyester during laundering. Polyester recycled twice shed about 4.3x more, and polyester recycled 3 times shed about 6.2x more.
A 2022 international house-dust study found microplastics in dust from 108 homes in 29 countries. It also modeled the highest dust-related dose for infants.
Recycling still matters for waste reduction. But for soft products used near babies, recycled polyester is not automatically the best choice. Fiber type matters.
What to do at home
For baby blankets, pajamas, crib sheets, and soft toys, choose organic cotton, wool, bamboo, or other non-polyester textiles when you can. Wash new textiles before use and clean lint and dust often.

What to use instead
For soft baby textiles, organic cotton blankets and clothing are a better fit than recycled polyester fleece.
