The flammability of flame-retardant Oxford fabrics is mainly judged from the ignitability, which is the high fire point. The low fire point indicates the difficulty of the fabric catching fire. The burning performance of the fabric is the flame retardancy.
On the other hand, it depends on the burning performance of the fabric: one is to judge from the burning rate of the fabric. It means that the fabric after flame retardant finishing is exposed to the flame for a certain period of time according to the prescribed method, and then the flame is removed, and the time for the fabric to continue burning with fire and the time for burning without flame is measured, as well as the degree of damage to the fabric. The shorter the flame burning time and the flameless burning time, and the lower the degree of damage, the better the flame retardant performance of the fabric; otherwise, the fabric has poor flame retardant performance.
The other is to judge by the oxygen index: fabrics require oxygen to burn. The oxygen index is an expression of the oxygen required for fiber burning. Therefore, the flame retardant performance of the fabric can be determined by measuring the oxygen index. The higher the oxygen index, the longer the combustion process will be maintained. The higher the oxygen concentration required, the more difficult it is to burn: this index can be expressed by the minimum volume percentage of oxygen required for the sample to maintain candle-like combustion in a nitrogen and oxygen mixed gas. If the oxygen index is less than 20%, it is a flammable fiber; if the oxygen index is between 20 and 26%, it is a flammable fiber; if the oxygen index is between 26 and 34%, it is a flame-retardant fiber; if the oxygen index is above 35%, it is a non-flammable fiber.
