Synthetic: The most commonly used synthetic fabric is polyester. Because polyester is more durable and water resistant than cotton fabrics, it is often a top choice for athletic wear and loungewear.
Currently polyester or polyester blends are the most commonly used fabrics in clothing production, surpassing cotton and all other natural fabrics. Derived from heavy pollutants such as fossil fuels and created entirely in a laboratory, polyester production is an extremely energy-heavy process that requires the quick heating of materials. The cooling process then requires an abundance of water, which is contaminated after use.
Due to their chemical properties, polyester fabrics emit nearly double the amount of toxic greenhouse gases such as carbon dioxide into the atmosphere than cotton. Lastly, polyester products are not biodegradable, meaning that when they end up in landfills it takes anywhere from 20 to 200 years to decompose.
