Flame-retardant fabrics are generally divided into two types, one is a post-treatment processed flame-retardant fabric, and the other is a natural flame-retardant fiber fabric. If it is a flame retardant effect, of course, the best is aramid flame retardant fabric, which has permanent flame retardant. If you want to choose the finishing flame retardant fabric, it is necessary to judge the flame retardant effect of the manufacturer's flame retardant technology.
The fabric woven from aramid flame retardant fiber has good dimensional stability and can be used for a long time at a temperature of 250 degrees Celsius, and its heat shrinkage rate is only 1%. The fiber softening temperature is 373 degrees Celsius, and it begins to decompose when it exceeds 400 degrees Celsius. When the fabric is decomposed, the cloth surface is thickened, the fiber is expanded, and the heat is transmitted from 900-1300 degrees Celsius outside the cloth surface without
