Which fabrics are most sustainable?
LINEN: is a plant-based fabric made from flax which can be grown on rough terrain that’s unsuitable for food production. It can be cultivated and processed without chemicals, though this is more commonly found in Europe and less so in China.
COTTON: is a natural plant-based fiber that makes up a quarter of all fabric used in clothing, furniture, and other textile blends, such as rayon and synthetics. It is a durable, breathable, and highly versatile fabric.
WOOL: If you’re comfortable with the fact that wool is an animal product, this could be the most environmentally friendly option. Wool is tough, wrinkle-resistant, resilient (which means good at retaining its original shape), and it can “absorb up to 30 percent of its weight in moisture before feeling damp”.
It holds colorful dyes easily, without use of chemicals.
Wool can replace many of the water-resistant synthetics and polyester fleeces that feature prominently in outdoor gear without fear of microfiber shedding – which, one could argue, wreaks havoc for wildlife down the food chain, despite being vegan.
The biggest issue with wool is the methane emissions from burping sheep. An estimated 50 percent of wool’s carbon footprint comes from the sheep themselves, as opposed to other fabric industries whose larger emissions hail from the fabric production process. These sheep, however, are usually raised on non-arable land.
POLYESTER: currently dominates the clothing industry, found in 60 percent of clothing. People like it for its stretchiness, durability, and comfort, but it’s important to remember that it’s a plastic manufactured from crude oil (an energy-intensive process). Even though some manufacturers are adding recycled polyester, often sourced from plastic bottles, to their fabrics, these have the same environmental repercussions as new polyester, which researchers are only just starting to understand.
What we know now is that every wash releases plastic microfibers into waterways and these persist indefinitely, contaminating lakes and oceans and getting ingested by animals and, indirectly, by humans.
WHAT TO DO?: choose organic fabrics whenever possible. These are more expensive, which means you’ll likely buyless but that’s a good thing, too. We need to break free from the fast fashion mentality that encourages rapid turnaround times on trends and a quasi-disposable attitude toward clothes.
