The burning rate of flame-retardant Oxford fabric is used to identify it. It means that the Oxford fabric after flame retardant treatment 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 continuous fire burning and non-flame burning is measured, as well as the degree of damage to the Oxford fabric. . The shorter the flaming burning time and the flameless burning time, and the lower the degree of damage, the better the flame retardant performance, and vice versa.
That means 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. Indicators: The oxygen index is lower than 20%, which is a flammable fiber; the oxygen index is between 20 and 26%, which is a flammable fiber; the oxygen index is between 26 and 34%, which is a flame-retardant fiber; the oxygen index above 35% is a non-flammable fiber .
It can also be judged by the oxygen index: combustion requires oxygen. The oxygen index is an expression of the oxygen required for fiber burning. Therefore, the flame retardant performance of Oxford fabrics can be determined based on the oxygen index. The higher the oxygen index, the higher the oxygen index required to maintain combustion. The higher the oxygen concentration.
What are the specifications of Oxford cloth? Such as 1680D, 1200D, 900D, 600D, 420D, 300D, 210D, 150D and other Oxford cloth. Function classification of Oxford cloth: fire-retardant cloth, waterproof Oxford cloth, PVC Oxford cloth, PU Oxford cloth, camouflage Oxford cloth, fluorescent Oxford cloth, Printed Oxford cloth, composite Oxford cloth, etc.
