A Simple Guide to Sustainable Fabrics

What comes to mind when you think about sustainable fashion? Is it thrifting, repairing clothes, or buying from eco-conscious brands? All of this is true…however, one of the biggest factors in fashion’s environmental impact is something many people overlook: the fabric itself!

Every piece of clothing is made from a unique material, and each one has its own footprint. This can range from how much water it takes to produce, to how it’s processed, and even how it breaks down (or doesn’t) once it’s no longer wearable. The good news? You’re HERE! Learning a little about fabrics can help you make smarter, more sustainable choices when shopping or cleaning out your closet.

🌱 Quick Breakdown of Common Fabrics

  • Cotton → High water use | Biodegradable
  • Polyester → Low water use | Non-biodegradable | Releases microplastics
  • Nylon & Spandex → Low water use | Non-biodegradable | Releases microplastics
  • Acrylic → Low water use | Non-biodegradable | Hard to recycle | Releases microplastics
  • Linen & Hemp → Low water use | Biodegradable
  • Silk & Wool → Low water use | Biodegradable | Require extra care

 

💧 Water Use vs. Biodegradability

You may be wondering what some of these terms mean but no worries, let’s break it down:

  • High vs. Low Water Use
    Fabrics like cotton need a lot of water to grow and process, making them resource-heavy and one of the reasons why they’re more expensive. On the other hand, synthetics (like polyester or nylon) require less water to produce, which makes them easier to mass-produce and cheaper to buy.
  • Biodegradable vs. Non-Biodegradable
    Biodegradable fabrics (like cotton, linen, hemp, wool, and silk) will break down naturally at the end of their life without leaving harmful traces behind. Non-biodegradable fabrics (like polyester, acrylic, nylon, and spandex) are often plastic-based, meaning clothing made from these materials can sit in landfills for decades before even beginning to break down.
  • The Microplastic Problem
    Aside from lingering in landfills, synthetic fabrics release tiny plastic fibers (known as microplastics) every time you wash them. These fibers enter waterways and contribute to ocean pollution.

 

So, while synthetic fabrics may save water during production, their long-term environmental impact makes them far less sustainable.

As you can see, there’s no single “perfect” fabric. But understanding the pros and cons of each can help you make better choices. Fabrics like linen, hemp, silk, and wool tend to have the lowest long-term impact (though they may require extra care). Meanwhile, polyester, nylon, acrylic, and spandex are durable and practical, but as synthetic fabrics, they contribute heavily to microplastic pollution.

🌍 Next time you’re shopping, take a second to check the tag for fabric details, and remember: the materials you wear matter just as much as the style!
