How to judge the flame retardant performance of fire-retardant Oxford fabric, we will introduce two methods to you.
On the one hand, it depends on the burning performance of Oxford cloth fabrics: from the flame retardant fabric To judge the burning rate, the flame-retardant finished fabric is in contact with the flame for a certain period of time according to the prescribed method, and then the flame is removed, and the time for the flame-retardant cloth to continue burning with fire and the time for burning without flame are measured, as well as the time for the flame-retardant cloth to continue burning. The extent of damage. 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 flame retardant fabric; otherwise, the flame retardant performance of the fabric is poor.
The other is judged by the oxygen index: flame retardant cloth will not burn Oxygen is required. The oxygen index is an expression of the oxygen required for fiber combustion. Therefore, the flame retardant performance of the flame retardant cloth can be determined by measuring the oxygen index. The higher the oxygen index, the higher the oxygen concentration required to maintain combustion, which means the more difficult it is to burn. : This index can be expressed by the small volume percentage of oxygen required for the sample to maintain candle-like combustion in a mixed gas of nitrogen and oxygen. 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.
