What Parents Should Know? Microplastics in Kids' Clothes:

Aug 4, 2025by Leslie Berbit

When it comes to children’s clothing—basics, underwear, sleepwear, and loungewear—microplastics are an invisible problem that often goes unnoticed. Many kids’ clothes contain synthetic fabrics like polyester and nylon, which shed tiny plastic fibers every time they’re washed. These microplastics don’t just harm the environment; they can also carry chemicals that disrupt hormones and affect health.

Why Are Synthetic Fabrics Common in Kids' Clothes?

Softness, affordability, and durability make synthetic fabrics popular choices for children’s clothing. They often provide stretch and comfort, but this comes with the hidden cost of microplastic pollution and potential chemical exposure.

Microplastic Fabrics: High vs. Low

Fabric Type

Microplastic Shedding

Typical Use in Kids' Clothes

Polyester

High

T-shirts, underwear, basics

Nylon

High

Activewear, some underwear

Spandex/Elastane

Moderate (used in small amounts)

Added for minimal stretch in lounge and basics

Recycled Polyester

High

Eco-friendly labeled but still plastic-based

Cotton (Organic)

None

Basics, underwear, sleepwear

TENCEL™ Lyocell

None

Soft basics, sleepwear

Hemp/Linen

None

Breathable basics and loungewear

What About Endocrine Disruptors?

Many synthetic fabrics are treated with chemicals like flame retardants, dyes, and finishes that can interfere with hormones—called endocrine disruptors. Kids are especially vulnerable to these chemicals, which can affect development and long-term health.

👕 Parent’s Playful Checklist: Choosing Kids’ Clothes Without Microplastics

Here’s a simple, fun guide to keep your little ones comfy and safe!

  • 🌿 Pick natural fabrics like organic cotton, TENCEL™ lyocell, hemp, or linen—soft and gentle on skin!

  • 🏷️ Look for certifications like GOTS or Oeko-Tex to avoid harmful chemicals.

  • 🤸♂️ Choose clothes with minimal stretch—a tiny bit of spandex/elastane is okay but keep it low!

  • Say no to 100% polyester, nylon, or recycled synthetics in basics and underwear.

  • 🧼 Wash gently and air dry whenever possible. If using a dryer, tumble dry low to reduce microfiber shedding!

 


 

By making mindful choices, parents can reduce microplastic pollution and protect their kids from unnecessary chemical exposure. Choosing natural fabrics isn’t just better for the planet—it’s kinder to your child’s health, too!
