The flame-retardant properties of 7031 electrical polyester fiber nonwoven fabric are primarily achieved through the material's chemical composition and physical structure. Polyester fiber itself possesses a certain degree of flame retardancy, but this can be further enhanced by adding flame retardants. At high temperatures, flame retardants decompose and release flame-retardant gases, such as nitrogen or carbon dioxide. These gases dilute the concentration of flammable gases, inhibiting the spread of flames. Simultaneously, flame retardants promote the formation of a char layer, which isolates oxygen and heat, preventing the combustion reaction from continuing. The stability of the char layer is crucial for the flame-retardant effect; high-quality flame retardants can form a dense and resistant char layer.
