Evaluating the flammability of fabrics is mainly considered from two aspects: on the one hand, the level of ignition point, which indicates the difficulty of ignition of fabrics. ; On the other hand is the flame retardancy of the fabric.
The method to evaluate the flammability of fabrics: First, evaluate based on the burning rate of the fabric, that is, measure the degree of damage after the fabric is in contact with the flame for a specified period of time. ; The other is judged by the oxygen index. The oxygen index is an expression of the oxygen concentration required when the fabric is re-burned. The flammability of the fabric is judged by determining the level of the oxygen index.
Testing methods for the performance of flame-retardant fabrics: There are various combustion test methods, and it is difficult to compare the test results of various test methods with each other. The experimental results can only To a certain extent, it explains the advantages and disadvantages of fabric burning performance. Our country currently mainly uses GB/T5455-1997 “Vertical Method for Textile Combustion Performance Testing” to test the flame retardancy of fabrics.
The flame-retardant fabrics produced by City Textile comply with European standards EN11611/EN11612, American standards NFPA2112 and Chinese national standards GB8965.1, etc. Multiple flame retardant standards.
