Methods to judge the flame retardant performance of flame retardant fabric

Flame retardant, performance, method
The basis for judging the flame retardant performance of flame retardant fabrics is usually based on the flame retardant Use the burning rate of the cloth to judge. The flame-retardant fabric is exposed to the flame for a period of time according to the prescribed method, and then the flame is removed, and the time for the fabric to continue burning with flames and flameless burning is measured, as well as the degree of damage to the 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 of the fabric; on the contrary, it means the fabric has poor flame retardant performance.
The testing methods of flame retardant fabrics are diverse due to different principles, equipment and purposes. It is difficult to compare the test results of various test methods with each other, and the experimental results can only explain the combustion performance of the sample to a certain extent. The combustion experiment method is mainly used to test the combustion extent (carbonization area and damage length), afterburning time and smoldering time of the sample. Therefore, Europe and the United States have corresponding flame retardant testing standards, and the standards have detailed regulations. When customers purchase flame retardant fabrics, whether they meet European and American flame retardant standards is also a condition for judging the quality of the fabrics.
