Fabric flammability is an important textile issue, especially for stage drapery that will be used in a public space such as a school, theatre or special event venue. In the United States, Federal regulations require that drapery fabrics used in such spaces be certified as flame or fire-retardant.
The U.S. Flammable Fabrics Act is an act that was passed in 1953 to regulate the manufacture of highly flammable clothing. [1] [2] It was enacted after years of rayon viscose fabrics being proven to be the primary cause of quick starting, high temperature fires as well as having the secondary effect of causing illnesses in factory workers.

The law requires fabric to pass a smouldering test. The test exposes fabrics and foams to burning cigarettes for 45 minutes. The test exposes fabrics and foams to burning cigarettes for 45 minutes. The ignition and char level are measured, with the goal being that the cigarette extinguishes without the fabric or foam igniting.
Flammability is the ease with which a combustible substance can be ignited, causing fire or combustion or even an explosion. The degree of difficulty required to cause the combustion of a substance is quantified through fire testing. Internationally, a variety of test protocols exist to quantify flammability.
Incorporating flame-resistant additives into polymers became a common and relatively cheap way to reduce the flammability of polymers, [6] while synthesizing intrinsically fire-resistant polymers has remained a more expensive alternative, although the properties of these polymers are usually more efficient at deterring combustion.
The fabric is composed of very stable polymers that do not react with other substances, and therefore, self-extinguishes when exposed to fire. The fabric does not melt or drip – which ensures that the fabric will not stick to skin and or intensify injury. [2] In addition to being flame resistant, Defender M is also lightweight and breathable.
FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing). "FR" stands for "flame retardant", and does not denote that the material complies with the standard UL94V-0 unless testing is performed to UL 94, Vertical Flame testing in Section 8 at a compliant lab. The ...
Marko (UNE EN 11612) is a registered trademark for a group of flame retardant fabrics used in the manufacture of protective clothing for industrial sectors. It was developed in 1997 and marketed as a mark of quality protection. The fabric is a combination of modacrylic and cotton fibres.
