What is Polyester?

Polyester is a category of polymers commonly used in the textile industry. It is made by polymerizing a type of plastic known as polyethylene terephthalate (PET) through a chemical reaction involving dimethyl terephthalate (DMT) and monoethylene glycol (MEG).

Polyester is used in clothing because it is durable, resistant to wrinkles and shrinking, and can maintain its shape. It doesn't have direct health impacts when worn, but there are environmental concerns associated with its production and microplastics release when washed.

When you see polyester on a clothing label, it indicates that the product may possess qualities such as durability and resistance to various forms of wear and tear. It is a synthetic fiber, not derived from animal sources, making it suitable for vegan consumers.

Commonly found in: Blouses, Shorts, T-Shirts, Sweatshirts, Pants, Sweaters

What to watch

Polyester can release microplastics into water systems during washing.

Maintains shape well, adding longevity to garments.

FDA

The FDA does not specifically regulate polyester as it is primarily used in textiles rather than food or medical products.

Research

While physical health impacts on consumers are minimal, research highlights potential environmental concerns due to microplastics.

Vegan

Polyester is a synthetic fiber and is generally considered acceptable for vegan consumers.
