Polyester is a type of synthetic fiber that is commonly used in clothing and textiles. It’s important to learn a bit about polyester, its impact on both the environment and our health; and why you should NOT be a polyester investor.

Polyester is made from petroleum, which is a non-renewable resource. It’s refined through a process called polymerization, where the raw material is heated and mixed with chemicals to form long, strong fibers. These fibers are then spun into thread, which can be woven or knitted into fabric. The primary factors and attribute behind it’s production is that it’s more cost effective for manufacturers and production. It’s great for the oil industry, yet not so much for you.

One of the biggest environmental concerns with polyester production is the use of fossil fuels. The process requires a significant amount of energy, which contributes to greenhouse gas emissions and other toxicities into the atmosphere. Plus the production of polyester requires large amounts of water, which can strain local resources and cause pollution when wastewater is discharged. Not to mention the tremendous amount of chemicals introduced to turn into durable fabric often include lead, formaldehyde and other cancer causing chemicals.

Besides the environmental impact, polyester also has potential health hazards. Here are three ways polyester can be harmful when you wear it:

1. Skin irritation: Polyester fibers can be itchy and cause skin irritation, especially in people with sensitive skin.
2. Breathability: Unlike natural fibers such as cotton or linen, polyester doesn’t breathe well. This can cause you to feel hot and sweaty, especially in warm weather.
3. Microplastics: When you wash polyester clothing, it sheds microfibers that can end up in our waterways and harm marine life. These microfibers are also believed to be harmful to human health, as they can be ingested through drinking water or by consuming contaminated seafood.

Despite its negative impact, polyester remains a popular choice for clothing manufacturers due to its durability, affordability, and is in over 50% of overall off the rack clothing production. There are sustainable alternatives available, such as cactus or mushroom based leather over cheap faux “vegan” vinyls/pleathers. Mi Terro is innovating a fabric that’s derived from milk is the base.

So while polyester may be a convenient and cheap option, it’s important to consider its impact on the environment and our health. Especially if you have passionate concerncs on climate change, your clothing choices are among the most important. By choosing sustainable alternatives and being mindful of how we care for our clothing, we can make a positive impact on our wardrobe and the world around us.
