Are mechanically recycled polyester clothes safe for infants with sensitive skin?

What's actually in it

Mechanically recycled polyester is made by shredding used plastic into fibers. This process creates weak, short fibers that break off easily. When your baby wears these clothes, they are constantly shedding microplastics (tiny pieces of plastic) against their skin.

Because infants have thinner, more sensitive skin than adults, these shed fibers can cause irritation and friction. Unlike natural fibers, these plastic bits do not break down. They stay in the environment and on your baby's clothing long after the first wash.

What the research says

A 2026 study in Environ Sci Technol found that mechanically recycled textiles are a major source of microplastic fiber emissions. This peer-reviewed research confirms that the mechanical recycling process directly contributes to the release of these plastic particles.

The science is clear: recycling plastic into fabric does not make it safer for sensitive skin. Instead, it creates a material prone to shedding plastic debris throughout the life of the garment.
