Polyester / Nylon (Microplastic Shedding)
The question

Is Polyester / Nylon (Microplastic Shedding) safe in polyester clothing?

AvoidPolyester clothing

Synthetic textiles shed thousands of microplastic fibers per wash cycle that enter waterways and food chain. Microplastics have been detected in human blood, lungs, placenta, and breast milk.

What the research flags

  • Up to 700,000 microfibers shed per wash cycle per garment (PLoS ONE 2016)
  • Microplastics detected in human blood (Nature Medicine 2022), lungs, placenta, and breast milk
  • Act as carriers for chemical pollutants (PCBs, PAHs) into food chain
  • Marine microplastic contamination now ubiquitous — no pristine ecosystem unaffected

Regulatory
EU restricting intentionally added microplastics (2023 REACH amendment)
