Different fire retardant fabrics have different levels of durability when exposed to heat andflame. Normally, fabrics that are manufactured to be fire resistant are more durable under such conditions than natural fibers that are simply treated with chemicals to make them fire resistant. Polyester, for example, can be manufactured so that fire resistant properties are built into the structure of the fibers themselves.

One of the reasons that manufactured fire resistant fabrics are considered to be more effective at retarding fire than topically treated fabrics may lose their ability to resist fire over the course of time. This is especially true for fabrics that are regularly laundered。

One of the most common uses of fire resistant fabric is in the suits that fire fighters wear. These suits are usually made of the most durable fire resistant fabrics that are available, including cutting-edge fabrics that have fire resistant propertied built into the molecular structure of the fibers. Not only do these fabrics have to resist fire, but it is also important that they don’t char and thin when they are exposed to heat and flames. Furthermore, it is important that these fabrics conduct as little heat as possible so as to protect the firefighter from the high temperatures of a fire.
