The current fabric flame retardant performance tester is mainly composed of a box, an igniter, and a sample feeder. That is, each part is installed in the box to improve the safety of the tester when in use. The igniter ignites and burns the fabric, and the sample feeder is responsible for feeding the sample into the igniter. In this way, the flame retardant performance of the fabric can be tested through the tester.
