Why Polyester-Free Clothing Matters: A Sustainable Guide

With the meteoric rise of fast fashion, polyester has become increasingly common. And it’s easy to see why. Polyester is affordable, low maintenance, and convenient. But it is also a massive polluter.

Keep on reading to discover why polyester-free clothing matters, especially for contemporary Australians.

The rise of sustainable fashion in Australia

Due to customer demand for authenticity and environmental responsibility, sustainable fashion in Australia has grown from a fringe movement to a dominant force in the industry. Brands cannot rely on flimsy eco-friendly statements in 2025, as consumers, particularly Millennials and Gen Z, demand transparency and tangible impact.

Overview: About Polyester

Polyethylene Terephthalate, more commonly known as Polyester, is a type of polymer. The fabric is synthetic and generally made from petroleum.

Polyester as a fabric is known for being durable, affordable, and wrinkle-resistant. As a result, it has become one of the most commonly used fabrics worldwide. And it now accounts for 80% of the world’s synthetic fabric production.

Side effects of polyester clothing

Polyester clothing has multiple drawbacks, such as:

Negative environmental impact, as it is non-biodegradable
Lack of breathability: Polyester is less breathable than natural fibres like cotton or linen because of the densely woven synthetic fibres that trap heat and impede ventilation. Even while there are varieties that drain away moisture, regular polyester can feel unpleasant, particularly in hot weather.
Low absorbency: Polyester repels water instead of absorbing it because it is hydrophobic. This may result in discomfort in humid environments by causing perspiration to remain on the skin rather than be absorbed into the clothes.
Tendency to trap odours, which makes it bad for warm weather.

Benefits of choosing polyester-free clothing

Choosing polyester-free clothing has multiple benefits in the long run:

Reduced carbon footprint: Polyester-free clothing is sustainable and biodegradable. As a result, your carbon footprint is smaller.
Better skin health: Organic fabrics are mostly plant-based. So, they are kinder to your skin.
Durability: Most polyester clothing includes microplastics, which is why it degrades quickly. But polyester-free clothing is much more durable.
More breathability: Natural fabrics like linen and cotton provide improved airflow, which keeps you comfortable and cool.
More Sustainable: Unlike polyester, which takes centuries to degrade, organic fabrics break down naturally, lowering long-term waste.
Improved moisture absorption: Natural fabrics like cotton and linen tend to absorb sweat, keeping you fresh and comfortable, unlike polyester, which retains moisture.
More comfortable: Breathable textiles such as linen and bamboo effectively control temperature, making them perfect for hot or warm climates.

Alternatives to Polyester

Rayon/Viscose	Lightweight with a soft texture

How to check whether the clothing is polyester-free

To find out if a piece of clothing is free of polyester, begin by examining the fabric label—manufacturers must specify the material content, so look for phrases such as "100% cotton", "linen", or other natural fibres. If the label mentions "polyester" or "poly-blend", the item contains synthetic materials.

For a tactile check, polyester commonly has a smooth and somewhat slick feel, while natural fabrics are generally softer and breathable. Another option is the burn test—gently burn a small piece of the fabric (if it's safe to do so). Polyester melts and emits black smoke with a sweet chemical smell, while natural fibres burn cleanly and leave behind ash.

Additionally, take note of wrinkle resistance—polyester usually resists creasing, whereas cotton and linen tend to wrinkle easily. If you're uncertain, you can perform a static electricity test; polyester tends to create more static than natural fibres.

For a more technical approach, some apps can identify the fabric composition by using your smartphone camera. By employing these various techniques, you can confidently establish whether a garment is free of polyester before making a purchase.

Frequently Asked Questions

Q: What are some good alternatives to polyester?

Some of the best alternatives to polyester include linen, pure cotton, and rayon/viscose. All of them are more sustainable.

Q: Does polyester-free clothing require more care?

Although they might need milder washing, organic fabrics typically age well and are softer with time.

Q: How can I check whether the clothes don’t include any polyester?

Look at the label of the cloth; if it says "polyester" or "poly-blend," it is synthetic. On the other hand, labels for natural fabrics will read "cotton," "linen," etc.

Q: Where to buy polyester-free clothing?

In Australia, many retail stores including Myer, Target, Kmart, and Big-Box stores carry polyester-free clothing. You can also check out independent labels.
