Flame-retardant fabric 1. Tested in accordance with GB/T 8626, its combustion performance should meet the indicators specified in GB/T 8626 and no burning drippings are allowed to ignite the filter paper;
2. Tested in accordance with GB/T 8625, the average remaining length of each group of specimens is ≥375px (the remaining length of any specimen is >0), and the average peak flue gas temperature of each test is ≤200°C.
3. Tested according to GB/T 8627, the smoke density level (SDR) ≤ 75.
The quality of a flame-retardant fabric can be judged by the burning speed of the fabric. Contact the flame for a certain period of time according to the prescribed method, then stay away from the open flame, measure the time the fabric continues to burn, and the time the fabric is burned. The degree of damage and the fact that no harmful substances are produced to the human body and the environment while having good flame retardant properties indicate that the quality of this flame retardant Oxford cloth is very good. Flame-retardant fabrics automatically extinguish as soon as the fire source is removed, and the burning parts are quickly carbonized without melting, dripping or holes, reducing or avoiding burns and scalding, thus achieving the purpose of protection.
Good quality flame retardant Oxford cloth will be extinguished immediately after leaving the fire. It depends on the temperature and air flow (oxygen) of the fire at the time and the length of time it has been in this high temperature environment. If the oxygen index of textile materials is above 21% (the oxygen concentration in natural air is 21%), the textile product is self-extinguishing. According to the size of the extreme oxygen index, fabrics are usually divided into flammable (LOI less than 20%), flammable (LOI equal to 20%–26%), flame-retardant (LOI equal to 26%–34%) and non-combustible (LOI> 35%) four levels.
