Why Most Children’s Clothes Are Made From Plastic (And What Parents Can Do)

When we think about plastic in our children’s lives, we often picture toys, packaging or bottles.

But there’s one place many parents don’t expect to find it: their child’s wardrobe.

Today, a large proportion of children’s clothing is made from synthetic fibres like polyester, nylon and acrylic - all of which are derived from plastic.

In fact, polyester has become the most widely used fibre in the global fashion industry.

For many parents, this raises an important question:

What does it actually mean for our children to wear plastic every day?

The answer isn’t about fear, it’s about understanding, and making informed, balanced choices.

What Does “Plastic Clothing” Actually Mean?

When we say clothing is made from plastic, we’re referring to synthetic fibres.

These include:

• polyester
• nylon
• acrylic
• elastane (often blended with other fibres)

These materials are created through chemical processes using petroleum-based resources.

They are popular because they are:

• durable
• stretchy
• wrinkle-resistant
• affordable

This is why they are widely used in:

• baby clothes
• kids’ pyjamas
• sportswear
• outerwear

 

Why Synthetic Fabrics Are So Common in Children’s Clothing

There are a few key reasons why polyester and other synthetic fabrics dominate the market.

1. Cost and Accessibility

Synthetic fibres are cheaper to produce at scale than many natural materials.

This makes them attractive for brands producing large volumes of affordable clothing.

2. Durability

Children’s clothes need to withstand:

• frequent washing
• spills
• rough play

Polyester is highly durable and holds its shape well over time.

3. Stretch and Convenience

Blended fabrics (like cotton-polyester mixes) offer:

• stretch
• flexibility
• easy care (less ironing, faster drying)

For busy parents, this convenience is appealing.

 

Why Some Parents Are Rethinking Plastic-Based Fabrics

While synthetic fabrics are practical, more parents are beginning to question how they interact with children’s bodies and environments.

1. Breathability and Comfort

Synthetic fabrics tend to be less breathable than natural fibres.

This means they can:

• trap heat
• hold moisture against the skin
• feel less comfortable in warm conditions

For children, especially babies, this can sometimes lead to:

• overheating
• heat rash
• skin irritation

2. Sensitive Skin and Eczema

Children are more likely than adults to experience:

• sensitive skin
• eczema
• irritation from friction or heat

Because of this, many parents choose softer, more breathable materials for everyday wear.

3. Microplastics in Everyday Life

Synthetic clothing can shed tiny fibres known as microplastics.

These can be released during:

• washing
• wearing
• general household use

They can accumulate in:

• indoor dust
• the air
• water systems

Young children may have higher exposure because they:

• spend more time on the floor
• frequently touch surfaces
• put objects in their mouths

4. Long Hours in Direct Contact

Babies and young children spend a significant amount of time:

• sleeping
• lying down
• cuddling soft fabrics

This means materials in:

• pyjamas
• bedding
• comfort items

stay in close contact with their skin for extended periods.

Natural Fabrics vs Synthetic Fabrics: A Simple Comparison

Feature	Synthetic Fabrics (Polyester, Nylon)	Natural Fabrics (Cotton, Wool, Linen)
Breathability	Low to moderate	High
Temperature regulation	Traps heat	Helps regulate body temperature
Feel on skin	Can feel less soft over time	Softens naturally
Moisture handling	Traps sweat	Absorbs moisture
Microplastics	Yes	No
Source	Petroleum-based	Plant or animal-based

This doesn’t mean synthetic fabrics are “bad”, but it helps explain why many parents prefer natural materials for items worn close to the skin.

Where Fabric Choices Matter Most

For parents who want to make changes, the good news is:

👉 you don’t need to overhaul everything.

Instead, focus on the areas with the most direct and prolonged contact.

1. Sleepwear and Bedding

Children spend up to half their day sleeping.

This makes pyjamas and bedding one of the most impactful places to start.

Many parents choose:

• organic cotton pyjamas
• breathable sheets
• natural fibre blankets

2. Everyday Basics

Clothing worn daily and close to the skin has the biggest impact on comfort.

Focus on:

• bodysuits
• vests
• leggings
• underwear

3. Comfort Items and Toys

Because babies often chew and cuddle these items, many parents prefer natural materials for:

• soft toys
• comforters
• blankets

4. A Balanced Approach

It’s not always practical, or necessary, to avoid synthetic fabrics completely.

Many families choose a balanced approach:

• natural fabrics for sleep and basics
• synthetics where durability or stretch is needed (e.g. outerwear)

What Parents Can Do (Without Overwhelm)

If this is new to you, start small.

A simple approach could be:

1. Switch to natural fibre sleepwear
2. Choose breathable everyday basics
3. Gradually replace items over time
4. Focus on progress, not perfection

Why This Conversation Matters

For many parents, this isn’t just about fabric.

It’s about:

• understanding what touches their child’s skin
• making more informed choices
• creating a healthier everyday environment

And importantly, doing so in a way that feels realistic and manageable.

The Bottom Line

Most children’s clothes today are made, at least in part, from plastic-based fibres.

That’s not necessarily something to fear, but it is something to be aware of.

Because babies and children have more sensitive skin and developing bodies, many parents choose to prioritise breathable natural fabrics where it matters most.

And the good news?

You don’t need to change everything overnight.

Small, thoughtful swaps, starting with sleepwear and everyday essentials, can make a meaningful difference over time.
