What Are Sustainable Fabrics?

To understand what sustainable fabrics are, it helps to look at the entire life cycle of a textile:

• Where and how the raw material is grown or produced

• How much water, energy, and land it uses

• Which chemicals are involved in processing and dyeing

• How long the fabric lasts

• What happens to it at the end of its life (recycling, composting, or landfill)

A sustainable fabric generally:

• Comes from renewable or recycled sources

• Uses fewer toxic chemicals and safer dyes

• Requires less water and energy to make

• Is durable, so you can wear or use it longer

• Is biodegradable or recyclable, rather than sitting in a landfill for decades

Choosing these materials helps you push back against fast fashion, a shift increasingly supported by research examining sustainability of fashion apparel and its broader environmental implications. Instead of constantly buying and sewing new items with resource-heavy fibers, you can create long-lasting pieces using fabrics that are kinder to the earth and to the people who produce them.

Key Characteristics of Sustainable Fabrics

What are sustainable fabrics? There are several key characteristics of sustainable fabric that set them apart from others.

Biodegradability

Biodegradability is a major characteristic of many sustainable fabrics. A biodegradable fabric can naturally decompose over time, especially when it isn't blended with synthetic fibers or coated with heavy finishes. This helps reduce landfill waste and pollution.

When you choose biodegradable fabrics like organic cotton, linen, hemp, or wool, you’re supporting a more circular economy, where materials can be broken down safely, or recycled into new textiles or products.

Whenever you can, pick fabrics that return to the earth more easily after a long, well-loved life.

Low Water and Energy Consumption

Sustainable fabrics reduce water and energy consumption in their production. By selecting these fabrics, you support reducing the massive amounts of water used in the textile industry.

Additionally, energy-efficient manufacturing processes ensure these fabrics have a lower carbon footprint. This means less energy consumption and fewer emissions throughout the product's lifecycle.

Reduced Chemical Usage

Another key characteristic of sustainable fabrics is reduced chemical use in growing, processing, and dyeing. For example, organic cotton is grown without synthetic pesticides or fertilizers, protecting soil health, water sources, and farm workers.

Many sustainable fabrics are dyed with low-impact or non-toxic dyes, instead of harsh chemicals that pollute rivers and harm local communities. Safer finishing processes avoid unnecessary coatings and treatments that can be harmful to both you and the environment.

For home sewers, this means you can feel better about the fabrics your skin touches all day long.

How to Identify Sustainable Fabrics

It can be hard to tell if a fabric is truly sustainable just by look and feel. That’s where labels and certifications come in. When you shop, check fiber content tags and product descriptions for labels such as:

• GOTS Organic: GOTS is a leading certification for organic textiles, ensuring at least 70% certified organic fibers. It restricts toxic chemicals, bleaching agents, and heavy metals, mandates proper wastewater treatment, and includes social criteria like safe working conditions and no child labor.

• OEKO-TEX STANDARD 100: OEKO-TEX STANDARD 100 prioritizes human health by testing every component of a product—fabric, thread, buttons, and zippers—against hundreds of harmful substances. While it does not guarantee organic farming or low-impact production, this certification ensures that the finished fabric is safe for skin contact.

• BLUESIGN: BLUESIGN evaluates the entire supply chain, not just the final product. It establishes strict standards for resource use, worker safety, and emissions, encouraging mills to adopt safer chemistry and production practices from the outset. When you see BLUESIGN-approved fabrics, you can trust that significant environmental and safety checks were involved in their creation.

• SA8000: SA8000 is a key social certification rooted in international human rights and labor standards. It addresses issues such as working hours, health and safety, and discrimination, applying to factories across various industries, including textiles. When a brand highlights SA8000-certified factories, it indicates a commitment to the human aspect of sustainability.

• Better Cotton Initiative (BCI): You may encounter BCI labels, which encourage farmers to use water more efficiently, promote better soil health, and reduce pesticide use while improving working conditions on cotton farms. While BCI cotton is not organic, it serves as a better alternative to conventional cotton and is a good option when fully organic choices are unavailable.

These certifications indicate that:

• The fiber may have been grown organically

• The finished textile has been tested for harmful substances

• Workers were treated more fairly

• Environmental standards were considered during production

Always take a moment to read the description, not just the marketing claims. Looking for these logos helps you sort truly sustainable fabrics from those that only sound green.

Types of Sustainable Fabrics: Natural Fibers
