Inherently flame-resistant (FR) fabrics are specially engineered textiles made from fibers that are naturally non-flammable. Unlike chemically treated fabrics, these fibers have built-in flame resistance that does not wash out or wear off over time. This ensures permanent protection without compromising comfort or durability.
Commonly made from aramid, modacrylic, or other high-performance fibers, inherently FR fabrics are widely used in industrial safety wear, firefighting gear, military uniforms, and electrical protective clothing due to their ability to self-extinguish and resist melting or dripping when exposed to flames.
