Fire retardant fabrics have received close attention from countries around the world. In particular, there are strict requirements on the performance, standards and environmental protection of fire-resistant and flame-retardant textiles. There are two methods commonly used in my country to evaluate the performance of flame retardant fabrics.
Method 1: The fire-proof and flame-retardant Oxford cloth that has undergone special fire-proof and flame-retardant technology is in contact with the flame according to the prescribed method. Within the prescribed time, the shorter the flame burning time and the flameless burning time, the greater the degree of damage. If it is low, it means that the flame retardant performance of the fabric is better. At the same time, if the flame retardant performance is good and there are no harmful substances to the human body and the environment, it means that the quality of the flame retardant fabric is better. On the contrary, the longer the burning time, the greater the degree of damage. , it means that the flame retardant performance is not good, and the generation of harmful substances means that the quality of the flame retardant cloth is extremely poor.

Method 2: It is judged by the extreme oxygen index (LOI) of Oxford cloth burning. Theoretically, if the oxygen index of textile materials is above 21% (the oxygen concentration in natural air is 21%), the textile product will be self-extinguishing. According to the size of the extreme oxygen index, fabrics are usually divided into flammable (LOI less than 20%), combustible (LOI equal to 20%–26%), flame-retardant (LOI equal to 26%–34%) and non-combustible (LOI> 35%) four levels.

The above four levels are tested The flame retardant performance is that the flame retardant function weakens and the flammability increases from large to small in order of extreme oxygen index. The above two methods are the more common standards for judging the flame retardant performance of fire-retardant Oxford cloth. Customers can customize Oxford cloth with different flame retardant effects according to their own needs.
