Is polyester flame resistant?

Q: I’m a workwear designer and I need to know each type of fabric feature for my work, I’d like to know is polyester flame resistant.

– Vassia Roditou

A: Polyester is generally considered to be more flame-resistant than some other types of fabric, such as cotton or rayon. However, it’s important to note that “flame-resistant” doesn’t mean “fireproof.” When exposed to flame, polyester doesn’t ignite easily and may self-extinguish, but it will melt and can cause severe burns if it comes into contact with the skin while melting.

There are also specially treated flame-resistant polyesters available, which are designed to resist ignition and prevent the spread of flames. These are commonly used in industries where fire risk is high, such as firefighting, electrical work, and certain types of manufacturing.

Keep in mind that while polyester has some inherent flame-resistant properties, safety standards, and regulations may require the use of specifically certified flame-resistant clothing or materials in certain settings. Always ensure your safety equipment meets the necessary standards for your situation.
