How to identify the flame retardancy of fire-retardant Oxford fabric, share two methods with everyone.
On the one hand, it is necessary to look at the burning performance level of Oxford fabrics: it is judged from the burning rate of flame-retardant fabrics, which means that fabrics sorted according to flame-retardant classification are The prescribed method is to contact the fire for a certain period of time, then remove the fire, and detect the time when the flame-retardant fabric still has fire burning and the time when there is no flame burning, and the degree of burning of the flame-retardant fabric. The shorter the flame burning time and the flame-free burning time, and the lower the degree of burning, the better the flame retardancy of the flame retardant fabric; on the contrary, the fabric has poor flame retardancy.
Another method is to judge based on the oxygen index: resistance Oxygen is necessary for burning fabrics. The oxygen index is an expression of the oxygen required for fiber burning. Therefore, the flame retardancy of flame-retardant fabrics can be determined by detecting the oxygen index. The higher the oxygen index, the higher the oxygen concentration required to maintain combustion, that is, Represents the harder it is to burn: This index can be expressed by the volume percentage of oxygen required for the fabric sample to always maintain candle-like combustion in a nitrogen and oxygen mixed gas. If the oxygen index does not exceed 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 flammable fiber. It is a non-combustible fiber.
