Flame retardant spun polyester yarn

Phosphorus-containing compounds are used as comonomers to make copolymers with dimethyl terephthalate and ethylene glycol through ester exchange and polycondensation, and then phosphorus-based flame-retardant polyester staple fibers are made through melt spinning, stretching and other processes. This method connects the flame-retardant structural unit to the macromolecular chain, which has permanent flame retardancy., flame retardant polyester fibers contain 6500 ppm of phosphorus, with an LOI of ≥32
Why Choose Flame Retardant Polyester Yarn

Permanent Flame Resistance
Inherent flame retardancy built into the fiber—lasts through washing, dry cleaning, and years of use.
Enhanced Fire Safety
Self-extinguishes quickly, reduces melt-dripping, and slows flame spread—critical for escape time.
Eco-Conscious & Low Toxicity
Phosphorus-based formula emits low smoke and minimal toxic fumes, meeting modern environmental standards.
Soft, Strong & Easy-Care
Keeps all the benefits of polyester: durability, wrinkle resistance, colorfastness, and a comfortable hand feel.
