Plastic-Free Clothing: How to Choose Clothes Without Polyester, Nylon or Elastane in 2026

Polyester, polyamide, nylon and elastane are now common on clothing labels — even in garments marketed around cotton, wool or other natural materials.

If you want to reduce synthetic fibres in your wardrobe, the most useful habit is simple: read the full composition label.

What is plastic-free clothing?

Plastic-free clothing is clothing made without synthetic polymer fibres such as polyester, polyamide or nylon, acrylic and elastane. Its textile composition relies instead on fibres such as cotton, linen, hemp, wool or silk.

This definition mainly concerns the fabric composition. Trims, zips, sewing threads, buttons and labels can have different materials, so a completely plastic-free finished garment requires checking more than the main fabric.

Is polyester plastic?

Yes. Polyester used in clothing is a synthetic polymer, most commonly PET, and is generally produced from fossil-based raw materials.

Turning PET into a textile fibre changes its form, not its nature as a synthetic polymer.

Is recycled polyester still plastic?

Yes. Recycled polyester, often called rPET, remains polyester. Recycling can reduce demand for virgin raw materials, but a garment made from recycled polyester is still a synthetic-fibre garment.

Terms such as recycled, responsible or sustainable describe different characteristics; they do not mean plastic-free. Read more in our guide to recycled polyester clothing.

Which fibres should you look for on a clothing label?

Viscose and lyocell are different again: they originate from cellulose but are manufactured through industrial processing, so they are generally described as man-made cellulosic fibres rather than natural fibres in the same sense as cotton, linen, wool or silk.

Is 95% cotton and 5% elastane plastic-free?

No. A garment containing 95% cotton and 5% elastane includes a synthetic polymer fibre. If your objective is clothing made exclusively from natural fibres, every percentage on the label matters.

Elastane provides stretch and shape recovery, which explains why it is frequently added to fitted garments. But 100% cotton and 95% cotton / 5% elastane are materially different compositions.

Why are synthetic fibres used so widely?

Synthetic fibres can be inexpensive, lightweight, durable, quick-drying and easy to engineer for particular functions. Elastane adds stretch, nylon provides resistance and polyester can improve shape retention.

Those properties can be useful in technical clothing. The more relevant question is whether they are necessary in every everyday garment.

Do synthetic clothes release microplastics?

Synthetic textiles can shed microscopic fibres during production, wear, washing and drying. ADEME notes that polyester and acrylic can release microplastics throughout the textile life cycle. Source: ADEME.

Shedding depends on fibre type, fabric construction, age and washing conditions, which is why durability and garment care matter alongside composition. See our guide to microplastics and ways to reduce exposure.

Are natural fibres automatically sustainable?

No. Natural does not automatically mean impact-free. Cotton cultivation, livestock, dyeing, finishing, transport and garment care can all contribute to environmental impact.

The better approach is to consider the complete life cycle: choose an appropriate fibre, favour quality construction, wear garments for longer and avoid unnecessary synthetic materials where possible. ADEME similarly recommends prioritising durable garments and considering material origin and production methods. Source: ADEME.

What are the main natural alternatives to polyester?

• Cotton: soft and versatile for T-shirts, polos and sweatshirts.
• Linen: breathable and particularly suited to shirts, T-shirts and summer garments.
• Wool: insulating and useful for knitwear, trousers and jackets.
• Silk: lightweight, strong and fluid for premium lightweight garments.
• Hemp: a robust plant fibre that can be used alone or blended with other natural fibres.

There is no universal substitute for polyester: the right choice depends on the garment and its intended use. Learn more about why ERVERTE Paris prioritises natural fibres.

How to read a clothing composition label

Marketing names do not always tell the whole story. A “cotton sweatshirt” might be 80% cotton and 20% polyester; “wool trousers” might contain polyester and elastane.

1. Find the fibre percentages.
2. Read every fibre listed, not just the first one.
3. Identify synthetic fibres such as polyester, polyamide, nylon, acrylic and elastane.
4. Check secondary fabrics such as linings, ribbing and trims when available.

Can modern clothing be made without synthetic fibres?

Yes. Cotton, linen, wool, silk and hemp provide a broad material palette for contemporary clothing. The challenge is often industrial convenience rather than technical impossibility: synthetic fibres can reduce costs, add stretch or simplify standardised production.

Working without them requires careful fabric selection, construction and pattern making.

ERVERTE's approach: natural fibres and Made in France

At ERVERTE Paris, our approach starts with a simple principle: synthetic fibres should not be used simply because they have become the industry default.

Our collections focus on high-quality natural fibres and garments made in France, including organic-cotton polos, natural-fibre T-shirts, linen garments, wool trousers and silk pieces.

The objective is not to claim that one fibre is universally perfect. It is to choose materials suited to the garment and design pieces intended to remain relevant beyond a single season.

Why the subject matters in 2026

Textile regulation is changing in Europe. France adopted Law No. 2026-602 of 8 July 2026, aimed at reducing the environmental impact of the textile industry and addressing ultra-fast-fashion practices. Source: Légifrance.

At EU level, rules prohibiting large companies from destroying unsold clothing, accessories and footwear entered into application on 19 July 2026. Source: European Commission.

These measures do not create a legal category of “plastic-free clothing”, but they reflect a wider focus on composition, durability, circularity and product lifespan.

The simplest rule

Read the composition before buying. If you want clothing without synthetic fibres, look for 100% cotton, linen, wool, silk or hemp, or blends made exclusively from natural fibres. Look more carefully when you see polyester, recycled polyester, polyamide, nylon, acrylic, elastane or spandex.

Marketing tells the story of a garment. The composition label tells you what it is made from.

Frequently Asked Questions

Is polyester a type of plastic?

Yes. Textile polyester is a synthetic polymer, most commonly PET.

Is recycled polyester plastic-free?

No. Recycled polyester remains a synthetic polymer even when it comes from recycled sources.

Does cotton contain plastic?

Pure cotton fibre is natural, but a cotton garment can also contain polyester, elastane or other synthetic fibres. Check the complete composition.

Is elastane plastic?

Elastane, also called spandex, is a synthetic polymer fibre.

Is nylon plastic?

Nylon is a synthetic polyamide polymer.

How can I find polyester-free clothing?

Look for garments made from 100% natural fibres or blends composed exclusively of natural fibres, and read the complete fibre-composition label.
