There are many burning test methods for flame-retardant Oxford fabrics. It is difficult to compare the test results of various test methods with each other. The experimental results can only explain the quality of the sample’s burning performance to a certain extent. The combustion experiment method is mainly used to test the combustion extent (charring area and damage length), afterburning time and smoldering time of the sample. According to the relative position of the sample and the flame, it can be divided into vertical method, tilt method and horizontal method.
Flame-retardant Oxford fabric
China currently mainly uses GB/T 5455～1997 for testing the flame-retardant properties of clothing. “Vertical method for testing the combustion properties of textiles”. The principle is to place a sample of a certain size vertically in a prescribed combustion test chamber and ignite it with a prescribed fire source for 12 seconds. After removing the fire source, measure the afterburning time and smoldering time of the sample. After the smoldering stops, press Determine the length of damage using prescribed methods. This method can be used for the flame retardant properties of clothing fabrics, decorative fabrics, tent fabrics, etc.; the 45° tilt method is suitable for aircraft interior decoration fabrics; the horizontal method is suitable for carpets and other matting fabrics and automobile interior fabrics.
Oxygen index test
The oxygen index method of flame-retardant Oxford fabric is to clamp the sample. Put it vertically into a transparent combustion tube. There is an upward moving oxygen and nitrogen flow in the tube. Light the sample end, then observe the combustion phenomenon, and compare its continuous burning time or burning distance with the specified limit: through a series of tests in different concentrations In this kind of experiment, the lowest oxygen concentration can be measured, and the oxygen index method is more suitable for process experiments.
