High strength, low shrinkage, flame-retardant polyester filament (including color)

     High strength and low shrinkage flame retardant polyester filament has high tensile strength, which is usually significantly higher than ordinary polyester filament. When affected by high temperature or other external factors, its shrinkage rate is low, and it has good flame retardant properties, which can effectively prevent the spread of flames, reduce the speed and degree of combustion. Polyester itself has good chemical stability, and high strength and low shrinkage flame retardant polyester filament also inherits this characteristic.
