How to identify the fire retardant effect of 600D Oxford cloth? Don’t worry, the flame retardant Oxford cloth comes with a test report, safe and reliable! Let’s take a look at some methods to identify its flame retardancy.
One can look at its burning performance, which can be distinguished from the burning rate of flame-retardant Oxford fabric. It means that the Oxford cloth fabric that has been flame-retardant 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 time is measured, as well as the degree of damage to the Oxford cloth 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; on the contrary, the flame retardant performance is poor.
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 by measuring the oxygen index. The higher the oxygen index, the higher the oxygen index required to maintain combustion. The higher the oxygen concentration, 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 less 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 is 35 More than % are non-combustible fibers.
Flame retardant Oxford cloth specifications include: 210D, 300D, 420D, 600D, 900D, 1200D, 1680D Oxford cloth fabrics, etc., which have different flame retardant effects, such as (extinguished when removed from fire), extinguished in 5 seconds after leaving open flame, waterproof and flame retardant, etc. Consultation hotline: 400-8380917
