Inherently FR Clothing Fabrics
Inherently FR fabrics are made by knitting or weaving fibers made from materials that are flame resistant in their own right. These inherent fibers are synthetic materials engineered to have their own flame resistant properties—many will not ignite at all when exposed to flame in an environment with normal levels of oxygen present. Inherent fabrics typically offer higher Thermal Protective Performance scores than treated fabrics, meaning they can protect wearers from higher temperatures. They also tend to be lighter in weight.
