How to identify the flame retardant performance of fire-retardant Oxford fabric
How to identify and judge the flame retardant performance of fire-retardant Oxford fabrics, we will introduce two methods to you.
On the one hand, it depends on the burning performance of Oxford cloth fabrics: judging from the burning rate of flame-retardant fabrics, that is, the fabrics that have been flame-retardant finished are in contact with the flame for a certain period of time according to the prescribed method, and then removed Flame, determine the time the flame-retardant cloth continues to burn with fire and the time without flame burning, as well as the degree of damage to the flame-retardant cloth. 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.
In the test of flame-retardant Oxford cloth, the oxygen index reached 33.6
Another One is to judge by the oxygen index: flame-retardant cloth requires oxygen to burn. The oxygen index is an expression of the oxygen required for fiber burning. Therefore, the flame-retardant performance of the flame-retardant cloth can be determined by measuring the oxygen index. The higher the oxygen index, the better. The higher the oxygen concentration required to maintain combustion, the more difficult it is to burn: this index can be expressed by the small volume percentage of oxygen required by 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.
