A substance added or a treatment applied to a material in order to suppress, significantly reduce or delay the propagation of flame.
A the time of production of the fabric, a chemical application process is adopted by which flammability of fabric is reduced.
Flame retardant fabrics have been treated with a flame proofing compound. These fabrics retain this fire retardancy for a limited time. Typically, flameproofing chemicals are water soluble and painting, washing, etc negate the fire retardancy. Excessive humidity may also reduce the flame retardancy over time. These fabrics can be re-flameproofed.
A chemical applied to a fabric, or incorporated into the fiber at the time of production, which significantly reduces a fabric's flammability.
