Wool vs acrylic? Cotton vs polyester? Hemp vs nylon? I know the natural fibres are typically more comfortable to wear, but what’s better for the environment?
You might think it’s a simple question – surely the natural stuff is better, right? But when you consider the impact of sheep on the environment or the amount of water required to sustain cotton crops, it does get you starting to wonder… especially when you factor in recycled (and sometimes recyclable) synthetic fabrics, like polyester made from old PET bottles.
Ultimately, I don’t know. I think I need to explore O Ecotextiles a little more and hope to be enlightened. At the moment, though, I’m leaning towards natural, especially when you look at the energy required to produce fabrics, the actual content of the fabric (oil in the synthetic fabrics is kinda off-putting) and the life of the fabrics after we’re finished using them (natural fibres will biodegrade, whereas synthetic ones won’t). Based almost purely on personal opinion, I think probably the best choice would be yarns produced from the by-products of some other industry (like soy yarns, which are made from soy fibres left over from making tofu), or yarn that is removed in a mutually beneficial way (alpaca removed by brushing, shearing pet sheep in summer etc).
Anyone know more and care to share?
