Polyester Flame-Retardant Yarn

Polyester anti-flaming yarn is a type of yarn made from polyester fibers that have been treated with flame retardant chemicals. Flame retardants are substances added to materials to reduce their flammability and inhibit the spread of flames in case of a fire. The primary purpose of incorporating flame retardants into polyester yarn is to enhance the fire safety of the end product, such as fabrics, textiles, or other materials made from this yarn.
